When you can’t Get Over it; Get UNDER It! XPM78-01 Möbius Progress Update Nov. 10-13, 2020

As you read this week’s Progress Update below you will understand what I am referencing in this week’s title as to how we solved the most recent challenge in the building of XPM78-01 Möbius by going under rather than over the problem.  Unfortunately on Friday (did it matter that it was the 13th?)  we were hit by a much different and much more challenging problem which there is just no getting over, around or under, when several workers at Naval Yachts tested positive and there was no choice but to shut the whole company for the next 17 days and do all the contact tracing and testing of all those employees who have been in direct contact.  If all goes well Naval, and certainly Christine and I, hope to reopen on November 30th.  I’m sure you join us in wishing everyone involved the very best wishes and that there are no serious health consequences for any of us here.

To be clear and not cause any undue concern on your part, as good fortune would have it, neither Christine or myself have had any direct contact with any of these workers for the past two weeks.  Furthermore, we have always been very self disciplined with our precautions of wearing masks any time there is any possibility of being in a place with others or where others have been recently such as the elevators in our apartment.  We are both quite naturally introverts and previous single handed sailors so it has been relatively easy for us to keep to ourselves and staying as much as possible.  And we are both quite fit and healthy, especially for two sixty somethings so I am pleased to let you know that we both feel very fit, healthy and happy and are doing everything we can to stay that way.

This may be as my kids used to say “TMI Dad!!”, as in Too Much Information to share, but the value of these kinds of blogs come in large part through their openness, transparency and honesty so I felt the need to share this brief insight into what is going on here and why there will not be much progress to report on for the remainder of this month of November.  Hopefully all will go well and Naval will reopen on Nov. 30th with all of us healthy so we can hit the ground running and get Möbius finished and launched ASAP.

Now back to our regular programming as I think they used to say on radio and TV, as I do have several fun and exciting things to update you on from aboard the good ship Möbius for the week that was November10th through 13th.

I think it is quite true that laughter is the best medicine so let me start by sharing this fun cartoon, courtesy of the appropriately named Bizarrow Comics who focuses on such topics as Pirates, Cowboys, Snowmen, Doctors, well you get the idea.

Mobius Dick cartoon image This was one of their Daily Comics this past week and it must have been making the rounds on the internet as several of you sent this to us right about the same time Christine and I were both seeing it.  Thanks Matt et al!

How appropriate and fun for us right?

Getting Under Mr. Gee

Let’s move on to the reference in this week’s title to a problem that we were able to solve by going under rather than over it.  To put it in context, this was part of Hussein and I working on the alignment of the whole “propulsion” unit formed by Mr. Gee being bolted to the Nogva CPP Servo Gearbox which in turn is bolted to the big 65mm / 2.6” SS prop shaft which has the big bronze 1 meter / 39.4” four bladed CPP prop on its far end.

That is a long description that is hard to track and I have received quite a few questions and comments about both the Nogva CPP (Controllable Pitch Propeller) and this whole alignment process so for those interested, let me break it down and provide more details.

Nogva CPP my simple dim hand sketch

Here is my very rough sketch from over a year ago when we were figuring out the exact dimensions for installing the aluminium Nogva Prop Log which is the “pipe” you see over on the far Left here. 
I’m hoping that this will give you the big picture view that helps to show how this Propulsion System is one solid mass from the front of the Gardner in Blue on the far Right, through the Nogva Servo Gearbox in Brown in the middle with the two flanges connecting to the Fwd/Right end of the prop shaft and over through the Prop Log, out through the end of the skeg where the CPP propeller in Green sits.

Nogva CPP my hand sketch This is the drawing above with some of the many dimensions I was pulling off of the actual installation at the time so I could double check that my 3D model of all this was exactly the same dimensions as the real deal.

No need for you to pay any attention to all these dimensions but I thought that this front to back view might be helpful for those trying to visualise this whole setup and see the relationships between all the individual parts.
Gardner & Nogva mounts screen shotNext up, let’s take a look at the six anti-vibration “feet” or mounts where Mr. Gee and the Nogva CPP are attached to the 25mm/1” thick engine beds running the full length of both sides of the Engine Room. 
I have never had enough time to create a full 3D model of Mr. Gee so you will have to use your imagination in the blank space to the Left of the Red Nogva Servo Gearbox, but hopefully this quick render of my Fusion 360 model will help you see how these six feet connect the whole Propulsion System to the Hull.
Front   Rear Gardner mounting brackets screen grabI initially created this 3D model when I was designing these custom brackets that bolt to Mr. Gee’ thick cast AL crankcase and create the eXtremely strong and rigid attachment points for the vertical threaded adjustment rods on each foot/mount.  Front mount is on the Left, Rear on the Right and both of these feet/mounts are the same anti-vibration models with thick rubber isolation blocks inside.
Engine isolation mounts image 1This is what those Front & Rear anti-vibration mounts look like and of course Mr. Gee requires the MMXL version!
PXL_20201112_065937889Back in the real world inside the Engine Room, this is Mr. Gee’s Front Port/Left foot after we have lifted the whole Propulsion System up with big chain hoists to drill the holes for the M16 Grade 8 bolts that will hold each mount solidly to the Engine Beds in precisely the right location Fore/Aft and Left/Right.
Nogva mounting bracket screen grabHere is a closer view of the mounting bracket I designed to be welded into the underside of the two Engine Beds and how these two different style of feet connect the Nogva CPP Servo Gearbox to the Engine Beds and Hull.  Also a good shot of the output flange on the Aft end which is what need to get so precisely aligned with the matching flange on the forward end of the Prop Shaft.
Volvo Penta motor mounts photo from Yach Boat Parts dot comHere is what these highly specialised feet/mounts on the Nogva look like in the manufacturers catalogue before I purchased them.  These start out being the same as any other feet/mounts by providing the rubber isolation that separates the upper body with the threaded rod from the metal base that bolts to the Engine Beds.  However if you look closely you will see that there are also two large diameter SS pins going side to side across the Base through the elongated oval shaped rubber isolation block.
PXL_20201112_083334231Here is a bit closer view one of those two Nogva feet in my hand to try and show you those two pins and the rubber isolation block.  Why are the Nogva mounts different than Mr. Gee’s some of you have asked.  Because in addition to providing the anti-vibration connection to the Engine Beds these also deal with the very significant THRUST forces which would otherwise be trying to push/pull the whole Propulsion System fore and aft as the propeller “bites” into the water and pushes the boat forward or reverse.
The Nogva Servo Gearbox is built to be mounted solidly to a hull with no anti-vibration mounts in large commercial vessels so it also has its own thrust bearing setup inside to fully deal with all these eXtreme Thrust forces.  However with one of our first principles being Comfort, the addition of these specialised thrust feet/mounts will help eliminate the transmission of vibration and noise to the hull and make for an eXtremely smooth and quiet boat when underway.

PXL_20201112_081122230This is what the real deal looks like as we were drilling the mounting bolt holes in the Engine Beds, hence all the AL chips.

Good shot of the custom Rear brackets bolted to Mr. Gee on the Left side and the underslung bracket for the Nogva feet/mounts over on the Right.
PXL_20201112_132637277Putting it all together, this shows you the whole Port/Left side of the Propulsion System with all three mounting brackets and their feet/mounts.

But hang on a minute …………………………………………

………………………… what the heck is that underneath Mr. Gee?!?!?!?!?!?

Let’s zoom in a bit closer to find out………………
PXL_20201112_132630050Aha!  So THAT is what this week’s title is referring to about “ When you can’t get Over it; Get Under it!”. 

So what was the problem that required raising the whole Propulsion up in the air and me spending all day Thursday up close and personal with Mr. Gee’s underbelly?

Well, as Murphy’s Law would have it, when Hussein drilled those two holes for the middle two feet on the Aft end of Mr. Gee, they turned out to be right on top of a 15mm thick vertical AL stringer running down the length of each Engine Bed.  Ugh!  This meant that while the threaded ends of the mounting bolts could go through there was no space for the washers and nuts underneath!!!  Grrrrrrrrr

Front   Rear Gardner mounting brackets screen grabGoing back to this render you can see that 15mm vertical stringer underneath the Front foot/mount where it was NOT a problem as the mounting bolts are further off centerline but if you follow that stringer Aft/Right you can see how it runs right through the centerline of the two bolts in the Aft Foot/Mount on Mr. Gee and hence this problem.

The solution?  A rectangular slot was going to need to be cut into the stringer where it was welded to the underside of the Engine Bed to create enough space for the thick washers and nuts to slide into.

PXL_20201112_132632913We tried to solve this problem by going Over the Engine Beds but as you can perhaps see, there wasn’t enough room to get in there with drills, Dremel tools, chisels and files.  We could have used a plasma gun but it would have spewed molten aluminium all over the Engine Room so that was a non-starter.

*someone* was going to need to go at this problem from the UNDER side.  As you may recall from seeing Hussein in some previous posts and down below, there as simply no way HE was going to fit in there, so guess who was elected???  No recount needed by the way!

With the Propulsion System firmly blocked up on all four corners I could pull out some of my Houdini moves and slither into this space with my headlamp and use various WMD, Weapons of Mass Deletion, to cut a rectangular slot in the vertical stringer under the four bolt holes.  I was one pooped Pirate when I finally got home to my Captain at the end of the day but it worked  as planned and there was now plenty of room for the nuts and washers for the bolts for these two middle feet/mounts to thread into.  Whew!

PXL_20201112_065648729Going back in time a bit, in order to lift the whole Propulsion System up in the air so I could get underneath to cut those four slots, Hussein, Nihat and I had rigged up these two lengths of square steel tubing that Nihat had welded large D-rings to the middle underside and spanned the big hatch in the Aft Deck. 
PXL_20201112_081117099We then hooked a large chain hoist onto each D-ring and connected their bottom hooks to straps around the front end of Mr. Gee and the built in lifting eye on the Nogva.

It all worked very well and also gave us a very safe and precise way just barely to take the weight off of the six feet/mounts so we could move them in their Goldilocks Just Right locations as we fully align the two flanges which is the next step in this process.


PXL_20201027_143240526This is the first part of the alignment challenge: get that male threaded end of the CPP Pitch Push/Pull rod coming out of the center of the Prop Shaft, PERFECTLY aligned with the female threaded Pitch Piston protruding out of the center of the output flange on the Nogva Servo Gearbox.

The prop shaft and pitch rod are fixed in position so they can’t move Up/Down or Left/Right, they both just rotate concentric with each other.  So the alignment has to happen by changing the angle of the Propulsion System.

PXL_20201027_141353695It is a slow and exacting process where we slide the feet/mounts to adjust the Left/Right position of the centre of the Nogva Pitch Piston/Flange and then adjust those big adjustment nuts on the vertical threaded rods on each of the six feet to change the angle of the Propulsion System and move the centre of the Pitch Piston/Flange Up/Down in the process.

It took several hours going back and forth from measuring and checking the Aft end here and then into the ER to tweak the six big adjustment nuts but as you can see here, we eventually hit the Goldilocks Jackpot and had the Push/Pull Pitch rod dead on center and ready to be threaded into the Pitch Piston.
PXL_20201027_150518040It was slow going turning the Pitch Piston with a wrench on those two flats so the bulb finally went on for me and I blocked the end of the wrench in position and then went outside and down to the Propeller and kept pressure pushing it forward while I rotated the bit 4 blade prop as if it were some eXtremely long bolt and that worked perfectly.
Nogva Pitch Control Rod   Flange dim dwg from Installation GuideThe last bit of precision is to get the length of that exposed threaded section of the Push/Pull rod above, to be precisely 7.5mm away from the aft end of the hex locknut as per the Nogva installation Manual you see here.  It can actually be between 5-10mm so I set it at the middle of this range at 7.5mm and torqued the locknut down to 100nm.

* for those curious, “Servo bevegelse 50mm” is Norwegian for “Servo Travel = 50mm”.  25mm on each side of “neutral” or Zero Pitch.

PXL_20201027_161424326With the Pitch Push/Pull rod all centred and locked in place I could now put on the two split halves of this Red Prop Flange and start the second phase of the alignment process.  This has two components to it; getting the mating flange surfaces precisely parallel to each other and also getting the two flanges equally perfectly aligned with each other axially. 
Nogva flange alignment dimsioned sketcch from installation manualThese two figures from the Nogva installation manual shows these two alignments very clearly and as you can see it needs to be eXtremely precise, no more than 0.05mm / .002”.  FYI, this is the thickness of THIN human hair.
PXL_20201028_093742501.MPThis will all be sounding very familiar if you were with me two weeks ago when Hussein and I when through the exact same process in order to find the precise location of the base of each foot/mount so we could mark out the location of the holes for their respective bolts.  This is a photo from that previous alignment and when we, hopefully, all get back to work on Nov. 30th we will do as Hussein is doing here and use thin feeler gauges to measure and ensure that the gap around the full circumference of where these two flanges mate, is exactly the same.  I.e., they are perfectly parallel.  To get there we go through the same adjustment procedure I outlined for getting the Pitch Push/Pull rod center aligned by sliding the feet Left/Right and/or turning the threaded adjustment nuts Up/Down.

I know this is not riveting stuff for almost any of you but this is such a critical part of having a smooth quiet Propulsion System that it gives me tremendous joy and satisfaction.  Fortunately it is also not a process you need to go through very often so well worth the investment in time now.


Nihat was the only member of Team Möbius on hand this four day week but he is one of our most relentless workers so he finished all his work on the Port/Left side of the hull and moved around the Bow to pick up where Uğur had left off last week.

PXL_20201111_132627390You can see the multi stage process quite well in this shot.  First the welds along each butt joint of the hull plates needs to be ground flat and flush such as you see running along Fore/Aft just below Nihat’s belt line.  Then any work marks on the surface of the plate need to be ground off which leaves a finish like the one on the far Left here.
PXL_20201111_132637944This nose on shot of the Bow shows the Start/End of this whole process with Nihat just getting started on the Left side of this photo (Stbd/Right side of the hull) which is in contrast with the surface finish on the opposite side that he has fully finished with a random orbital sander.
PXL_20201111_132646829Here is a shot looking straight onto that same finished surface.  The Waterline is about 200mm/8” above the weld at the bottom so that does not get fully ground down flush as this will all be covered wtih epoxy primer and International InterSleek 1100 foul release “Bottom Paint”, so we can use filler to get all the surfaces below the Waterline flat and smooth prior to painting these surfaces.

You Made this Bed; Now Lay in it!

PXL_20201113_115814966None of our interior crew was available this week but the big memory foam mattress has been cut to size and the cover sewn up for over a month now and it was going to be much easier to get it onboard before they put in all the glass windows around the Pilot House/Super Salon so I was able to get a strapping young worker from the boat next to us helm me wrestle the mattress aboard.

As is often the case with boat beds, their sides are no parallel and this was the case with the Right side here as it runs parallel with the side walls that curve in with the hull.  But Sinan our master upholsterer was able to quick cut the foam with his special electric knife and then resew the cut edge of the very nice mattress cover so it all fits in like a glove.
PXL_20201113_115827214 It was actually much easier than I thought it might be.  This is 30cm / 12” thick memory foam so we were able to bend it and flex it just enough to get it through the Entryway WT Door into the SuperSalon and then down that spiraling stairway into the Master Cabin in the background on the Left.

Captain Christine has not been able to be onboard for over a week so it will have to now wait until after Nov. 30th for her to come test it out.

When you get out of that Bed, Test out this Helm Chair!

PXL_20201113_122333580For similar reasons I wanted to get both our big Llebroc Helm Chairs aboard before the glass company arrives next week to install all the  SuperSalon glass windows and all the plexiglass windows around the whole upper SkyBridge.

PXL_20201113_122348521This is the LLebroc Tradewinds CX HB SERIES 2 Helm Chair now resting in its new home in front of the SkyBridge Helm Station.

We also moved the slightly different and just as cool Llebroc Bandera Series 2 Helm Chair into the Super Salon Helm Station but I didn’t get a chance to take any photos so you’ll have to wait till we get back onboard for me to show you that beauty.


PXL_20201113_080905556It felt very good for me to be finally moving things like these Helm Chairs onboard to their final resting place as it makes the Launching of Möbius feel that much closer and real.  I had the same feeling when I was also moving these three 18 litre/5 USG cans of hydraulic steering oil onboard on Friday.  This will soon be filling up our 55L hydraulic steering oil tank that feeds our whole Kobelt steering system and I’ll show you that as it happens.


Next up were these three cans with almost 60 liters / 15 USG or one of my favorite engine oils; Shell Rimula R4X 15W-40. 
PXL_20201113_081605823In addition to being a top quality engine oil I have found this to be one of the easiest brands to find most anywhere in the world as this is also commonly specified by the big diesel engine companies for use in tractors, trucks, cranes, etc. that are needed and used most everywhere.

I also moved all our anti-freeze onboard but didn’t get any photos, which I’m sure you are all so sad about. Not!!

And that’s all from your intrepid cub reporter here in Antalya Turkey for the week that was November 10 through 13th, 2020.  Hope you enjoyed this week’s abbreviated posting and I will be back with more next week.

Please do keep your questions and comments coming by typing them into the “Join the Discussion” box below.  They are eXtremely helpful and meaningful to both Christine and myself and MUCH appreciated.  Thanks!


Mr. GEE Gets a Standing Ovation; On ALL 4 Feet XPM78-01 Möbius Progress Update August 4-8, 2020

Last week was another 4 day work week due to Monday being the final day of the big 4 day long Eid al-Adha holiday here in Turkey and to exacerbate the impact on XPM78-01 Möbius the push at Naval Yachts to finish and launch two other boats continues so most of Team Möbius were reassigned to help out with those two projects.  However progress was made none the less as Hilmi, Selim, Christine and yours truly worked a full day yesterday (Saturday) so we turned it into a 5 day work week after all so I still have exciting progress to share with you in this week’s Show & Tell Progress Update so let’s just right into that.

Sparkies Keep the Flame Burning Aboard Möbius

Our one and only “Sparkie” aka Electrician Hilmi who is now ably assisted by the young and flinty (sorry couldn’t resist) Selim worked all four days this week and were also on the job all day Saturday with Christine and I so there has been lots of good progress on the many electrical jobs still needing to be completed.

IMG_20200806_165136Most of the wires and cables going into Möbius are already pulled but with literally miles of wiring in total even the remaining “little bit” is a lot.  Seen here, Selim is pulling some of the remaining cables coming up through the floor from the Basement into the Main Helm for all the controls, switches and electronics there.
IMG_20200806_165150Further back on the Aft Port side of the SuperSalon Hilmi and Selim took on one of the more challenging wire pulls with these cables that come up through the hollow in the window I-beams to get past the glass windows and up to the Upper Helm in the SkyBridge.
IMG_20200806_165206 A closer look peeking between some of these cables shows how these hollows in the massive 10mm / 3/8” thick aluminium I-Beams on either side of each window provide a just right channel for the cables to transit.

PGL sketch 67For those of you wondering why these I-Beams are so strong and thick, this quick render with all the outer plating removed shows how these Window I-Beams are part of each of the 23 full frames that make up the “skeleton” of the hull framing.  These frames are spaced 1 meter apart and are about 4-5 times what is required by classification standards for Open Ocean class boats.

Hull structure details AnnotatedThey need to be this thick and strong as they carry the full load from the superstructure of the Pilot House framing and transfer it down to the framing below. 
Bonus Points:  By using this I-Beam construction we also gained a built in wire chase every meter!

IMG_20200806_165305The cables exit the top of the I-Beam and feed into the Port side of this “doghouse” over top of the Entryway where the stairs take you from the Aft Deck down into the SuperSalon, and run up and then across to the Right side of this overhead electronics box and then ….
IMG_20200806_165246…….. feed into the Upper Helm through this AL penetration tube. 

After we are sure all the wires are in and everything has been tested and working, all these penetrations will be filled with special sealing compound to make them fully watertight.

IMG_20200807_182128Below the glass windows, the cables they are pulling here come up through these two removable panels that provide access to the Fuel Fill & Vent hoses on the Port hull beside the stairs going down to the Corridor.  There are cables for both AC and DC wiring at the Upper Helm as well as some N2K and ethernet wiring.

We refer to the cupboard partly visible in the very bottom Right corner as the “internet Alcove”.

IMG_20200806_095706Which which is the scene of more cable pulling this week, mostly consisting of the creamy white CAT-7 ethernet cables seen on the bottom Left.  The black box with all the antennae on the Left is our PepWave Max Transit Duo and black boxes on the Right rear corner are three of our Ethernet switches.

The White & Green box in the Left background is an outlier here as it is the main control or “brain box” for our In-Floor Heating system.

Cradlepoint-and-Peplink-routers from SeaBits SteveCourtesy of Steve Mitchel who singlehandedly runs the incredibly valuable marine electronics SeaBits blog, those of you wanting to do a deep dive into some of the latest and greatest routers for maximum cellular and WiFi connectivity should be sure to check out THIS Seabits article from Steve.  Christine and I are both huge fans of “Seabits Steve” as we refer to him almost daily as we anxiously await his latest posting to learn from.

FYI: We purchased our PepWave Max Transit quite awhile back so it is not the model behind this CAT 18 upgrade but still provides us with pretty awemazing connections to shoreside cellular signals and gives us a full WiFi bubble everywhere on Möbius.  The PepWave Max Transit series is built for use on busses, ferries and hence the “Transit” name so these are eXtremely robust and powerful routers which form the heart of our cellular/WiFi setup on Möbius.

IMG_20200806_095624At the bottom of the stairs in the Corridor where my “Clean room” workbench and office reside, Hilmi and Selim have mounted these two Furuno 711C AutoPilot FAP-7002 Processor Black Boxes.  The small Red unit Right of center is our ActiSense NGW-1 NMEA2000 Gateway and the little Blue box above is another Multi-Port 4 port box for N2K drop cables coming off the central N2K backbone.

IMG_20200807_141937Continuing our tour of the Port/Left side hull, if you look up to your Right as you go through the WT door at the end of the Corridor and enter the Workshop, you will see that Hilmi has now pretty much finished making all the connections for the N2K network cables including Multi-Port boxes such as the Blue/Purple one here on the far Left, Maretron Black Boxes for sensors from Maretron fuel & water tanks and other monitoring sensors. 
The two boxes on the far Right are the larger ActiSense EMU-1 box which puts the old analog data from Mr. Gee onto our N2K network so we can monitor and log things like temperature, pressure and levels of engine oil, water and CPP oil and RPM,

IMG_20200804_122153And finally for this week, if we go up front of the SuperSalon and down the stairs into the Master Cabin we find that Hilmi & Selim have been busy installing the indirect LED lights in the stair nosing and under each toe kick area.
IMG_20200804_122029Looks like this when standing on the stairs heading into the Master Cabin.
IMG_20200804_122142And like this up at the very front where the Vanity sink sits on the far Left and the full wall full of cabinets along the Port side of the hull.

All lights on Möbius are LED and all interior lights, direct and indirect are all on dimmers so the lighting can always be adjust to get it Just Right for any situation.

FYI; The colour of this indirect lighting looks very Green in all my photos which I think is due to them mixing with the big work lights illuminating all the rooms but they are all soft white in reality and have a very pleasing visual effect as well as a big safety factor.

Hydraulic Steering Tanks:

Rectangular Hydraulic Tank dim dwgUpon reading the manufacturer’s requirements and doing some math, a new main tank for the Kobelt hydraulic steering oil was required to meet their minimum 45L/12 USG capacity, so I fired up Autodesk’s Fusion 360 and came up with this design for a slightly oversize 53L / 14 USG tank that was the Goldilocks size and shape to fit just right overtop of the two Accu-Steer HPU400 steering pumps at the Aft end of the Workshop.
IMG_20200806_095433Uğur and Nihat were able to steal away from those other boats for a few hours on Thursday and Friday so I had the dimensioned drawings ready and waiting for them to quickly fabricate this rectangular tank and a small cylindrical header tank for the Kobelt manual hydraulic steering pump at the Main Helm.
IMG_20200806_140239I KISS’ed the design (Keep It Simple & Safe) to make it quick and easy to build and Nihat and Uğur are an excellent team and they had the tanks fabricated in no time.

These two “holey” inner plates we see Uğur welding here, provide baffles to reduce the free surface effect caused when any tank or a compartment is partially filled, the motion of the liquid due to the ship’s rolling and pitching motions would reduce the stability of the ship.

IMG_20200806_164658Nihat helping me do a quick test fit and determine the just right location for the tank and its mounts overtop of the two Kobelt Accu-Steer HPU400 hydraulic pumps and their respective hoses and valves underneath.
IMG_20200806_164706I was able to design this filler pipe to just fit into the cavity behind the AlucoBond wall panelling on the hinge side of the WT door where it will be easy to access but well out of the way as you walk in/out.
IMG_20200807_141841Uğur fabricated and welded these 15mm / 5/8” thick bosses or pads to add enough thickness for the pipe threads for the hydraulic fittings for the supply and return lines.
IMG_20200807_141859I added these two short pipes inside where the two supply fittings go to keep any dirt or debris that might sneak into the tank from getting out. 

There are also oil filters on the supply lines to keep the hydraulic oil meticulously clean so this is just some added protection for the extremely small tolerances of the hydraulic pumps and cylinders.
IMG_20200807_181833After a VERY thorough cleaning up of all the interior of the tank, Uğur could finish the tank by welding the top on. 
IMG_20200807_181844Those are slot welds he is laying down here which go through to the top edges of the baffle plates.
Round Hydraulic tank dim dwgKobelt requires a small header tank for their manual hydraulic steering pumps which is what we have at the Main Helm as an emergency backup should the double hydraulic AutoPilot systems ever both go down.  So I designed this very simple 1.5L tank that was just the right size and shape to fit out of the way underneath the Dashboard of the Main Helm.
IMG_20200807_094827Short length of 120mm OD aluminium pipe worked out just right.
IMG_20200807_141624Simple plate ends welded on to create the tank.
IMG_20200807_171209Minutes later, Uğur had it all welded up and ready for Cihan our Master Plumber to cut the NPT pipe threads in the supply and return pipes on the side.  The larger 50mm pipe on the top is to fill this tank and check fluid levels.

Both tanks now ready to be mounted next week.
IMG_20200806_130245One other small job they knocked off in a few minutes this week was welding these two hinges for the frame …..
IMG_20200806_130250…….. that holds the three solar panels on the front roof of the Pilot House.
IMG_20200805_100405This is how this front solar bank looks from the Foredeck when it is in the Passage Making mode.  (Aft panel removed here for welding the hinges you see above)
IMG_20200805_100508Using a short wooden support to show about how this Forward solar bank pivots on those aft hinges so the panels are horizontal or the optimal angle to keep them close to perpendicular to the sun.

But wait!   There’s more …………………….
IMG_20200805_100527Look what is at the Aft end of this wind tunnel formed by the bank of solar panels when they are propped up!  Yup, that’s a large mist eliminator grill that feeds directly into the big air plenum ……
MVIMG_20200710_182952 in the ceiling of the center of the SuperSalon with these five vent tubes which will have adjustable diffusers in them to control and direct the air flow.  As you can imagine, given the size of this “wind tunnel” formed when this bank of solar panels is propped up while we are anchored, even the slightest breeze will produce plenty of clean fresh air into the SuperSalon. 

But wait!  There’s more! ……………….
IMG_20200603_182826There are an additional five vents with diffusers up at the very front as well directly overtop of the Main Helm.  If you look closely (click to enlarge any photo) you will be able to see a series of slots cut into the overhang of the roof immediately in front of the center window where the negatively raked windows create a high pressure area which feeds fresh breezes into this forward set of air vents.

As I’ve pointe out previously, ventilation is such a critical factor for a comfortable and safe passage maker that we literally started designing the ventilation system and then built the boat around that.  This is the result and we will always be very well ventilated.
IMG_20200806_130755IMG_20200806_130812I received quite a few questions in the past asking for details on the solar panels we sourced directly from the manufacturer, Lightech Solar in China so here are shots of the labels with all those details for you. 

The front 3 panels are the 295 Pmax Watts and the other 11 panels are the 320 Pmax Watt panels.

Cables each have MC4 connectors which we will soon connect using MC4 in-line fuses.

IMG_20200804_152900One other bit of progress this week was that Orhan, our Teak specialist, finished building the three removable floor panels that go in the Master & Guest showers and the Master Bathroom/Head.

The bottom surfaces of these lift out floors will be fiberglass to reduce any mold forming in this wet area.
IMG_20200804_152921Similar to the way he does solid Teak decking on other yachts, Orhan cuts these grooves along the edges of the individual Teak boards and then fills these with Black Sikaflex caulking.
IMG_20200804_152853A task made MUCH faster and easier using this pneumatic powered caulking gun!
IMG_20200804_152847He was only able to get these first three grooves in one floor panel by end of the work day on Friday but once he has all the grooves caulked the whole panel will be sanded down flat and flush.  We don’t allow any teak or any other woods or paint or stainless on the exterior in order to minimize maintenance but we thought this little bit of nautical teak “decking” would work work well in our showers.

Mr. Gee’s Coats of Many Colours

As I’m about to show you, it was a bit of the “three steps forward, two steps back” waltz with Mr. Gee and myself this week but that’s still one step of forward progress right?

IMG_20200805_142235One of the steps forward was getting the massive cast aluminium oil “pan” or Sump all put together and installed on Mr. Gee.  In addition to being eXtremely strong and weighing in at a svelte 45kg / 100 Lbs (my best guess as I can just barely lift it by myself) this baby holds 30 Liters/ 8 USG of engine oil in this deep sump at the aft end of the Gardner 6LXB.
IMG_20200805_142231I had previously given this a very thorough cleaning with the sandblaster and then flushed, cleaned and painted it with silicone based aluminium heat paint.  Last step was to now reinstall the wire screens you see resting on the far end.
IMG_20200805_142238These wire mesh grates bolt to this grid and would catch any large particles that might somehow fall into the sump and prevent them from getting down into the oil in sump before it is pumped out through all the oil galleries in the engine.

Note the same kind of baffling here to reduce that Free Surface Effect mentioned in building the hydraulic tanks.
IMG_20200805_182101Next step forward was to wrestle the now fully assembled Sump off my workbench and in place underneath Mr. Gee. 

FYI: It is averaging about 38C/100F most days here now so I consider this “dance step” to be part of my weigh loss campaign to keep my girlish figure! Winking smile
IMG_20200805_185140Gardner specifies RTV High Temp silicone for this joint and it is my preferred gasket making compound so that’s what I used to seal this Oil Bump to Crankcase joint.

You can see the wire mesh grates installed inside and the oil pump pickup pipe extending down through a special spring loaded fitting on the upper Right.  The taped off holes are for the bronze pipes for pickups, dipstick tube, etc..
IMG_20200807_113559I used two hydraulic jacks underneath the Oil Sump to help me raise it slowly into place which is a bit tricky as there are ten studs and the oil pickup tube that all have to align just right but I soon had the Sump back where it belonged and Mr. Gee’s once again had his bottom end all covered up, so he was happy too.  42 bolts and studs later with some Loctite thread locker and the Oil Sump was all torqued up to just right tightness.
IMG_20200807_113550The “2 steps back” part of this week’s dance with Mr. Gee began when I took on repainting all of his cast aluminium parts.  Several months ago as you may remember seeing in previous posts, I had painted all these cast aluminium parts with some special high heat silicone paint that is basically aluminium powder suspended in clear liquid silicone. 

It seemed to work eXtremely well in terms of coverage and the look of “real aluminium”.  However I discovered too late that the aluminium is a bit too “real” and that even when fully cured the surface is raw aluminium dust so every time you touch it your fingers are covered wtih a light coating of the aluminium and the surfaces do not clean up well.
IMG_20200806_200234No problem he thought, just apply a good coat or two of clear epoxy and you will end up with a nice smooth, shiny, impervious outer “shell”.  In the time since though some areas had been banged up or had to be sanded down for mounts and other work so I needed to reapply another coat of this aluminium paint.

No problem right?  The clear coat had worked well going on top of the aluminium paint so you would think that doing the reverse, putting the aluminium paint on top of some of the clear should be no problem right?


Soon after applying the new coat of aluminium silicone paint, this began to happen!  For some reason the new coat of aluminium silicone paint reacted where the clear epoxy was.  Yikes!  Talk about two steps back!
IMG_20200805_132359No going back now so I resigned myself to the laborious task of immediately  removing most of the paint on these very uneven surfaces and repainting them all over again.  The paint was fresh enough that I found I could blast much of it off using a very high pressure compressed air nozzle which got me about a third of the way and then I had to resort to other weapons of mass reduction such as wire wheels, grinding disks and LOTS of hand sanding.

Oh, and did I happen to mention that is was a 40C/104F day?

So back to my weight loss regime and two days later I had masked off the upper cast iron cylinder block and heads and shot poor Mr. Gee with another full coat of aluminium silicone paint.

IMG_20200807_1135593 steps forward in that it looked pretty good.as you see here.  But 2 steps back on closer inspection!

If you click to enlarge and zoom in on the far Left side here you will see that Mr. Gee has some rather wrinkly skin.  Seems that I didn’t do quite as good a job of removing ALL that clear coat. 
IMG_20200807_170640However I was out of time now and so hopefully Mr. Gee and the Gardner Gods will forgive me for this less than ideal paint job and I proceeded to finish the whole paint job.
IMG_20200807_165726I needed to put on a second coat of the Burgundy epoxy paint on the upper cast iron cylinder block and heads so I removed all the masking I had put on them while doing the aluminium paint dance and then masked off all the bottom aluminium parts and gave the previous Burgundy paint a light hand sanding.
IMG_20200807_165750Fortunately this dance went very well as it was now working with familiar all epoxy paints and soon had Mr. Gee’ fully fitted with his new Burgundy coat.
IMG_20200808_175905I still needed to do something about that new coat of “raw aluminium” paint or else Mr. Gee was not going to stay looking too dapper for too long so I turned to a clear coat I had lots of good experience with, AlexSeal Premium Topcoat 501 Clear and did some extensive experimentation by applying coats to some test pieces I had sprayed with the aluminium silicone paint. 
IMG_20200808_175912Enough with the 2 steps backwards!

This final clear coat of Clear Premium Topcoat 501 over top of both the Burgundy epoxy and the aluminium silicone paints worked GREAT, matching my experience using AlexSeal for almost 20 years now.  Live and learn, Go with what you know!
IMG_20200808_180012I also prepped these other aluminium parts such as the intake manifold, coolant water header tank and many other bits and bobs by sandblasting, priming and then painting them all with the aluminium silicone paint so they were all ready for their final coat of clear AlexSeal in one final Last Dance for this week.
IMG_20200808_175941I wanted to do as much clear coating as possible so I also took the time to prep all these other parts, some cast aluminium such as the cooling water manifolds, thermostat housing AND ………….
IMG_20200808_175925These solid cast bronze beauties which are the two halves of Mr. Gee’s engine oil cooling heat exchanger.
IMG_20200808_175931Call me crazy, (and you’d right), but these start out as dull clunky Beasts and then after some thorough sand blasting and lots of wire wheeling, transform into some of the most Beautiful engine parts I’ve ever seen.

Oh, and I ran out of time this week so I did not even get to all the bronze and copper pipes and tubes which connect to these Bronze Beauties and other parts of Mr. Gee so you ain’t seen nothin’ yet!

Stay tuned for more of my dances with Mr. Gee and hopefully more steps forward than back in the weeks to come.
IMG_20200808_175953Oh, and for those of you still waiting for an explanation of that reference to “Mr. Gee’s standing ovation on all four feet”  check out this photo and several others above and see that the answer has been staring right at you…………

Yup, Mr. Gee is now standing on his very own on all four of his anti-vibration engine feet!  How else was he going to be able to dance with me???????
OK, till next week, this is your XPM78-01 Möbius cub reporter signing off with thanks for taking the time to join us for this week’s Show & Tell.  See you again next week I hope and PLEASE be encouraged to write your comments and questions in the “Join the Discussion” box below.


Independence Day Sparks & Fireworks Everywhere! XPM78-01 Möbius Progress Update June 29-July 4, 2020

Canadian Flag Canada Day fireworks photo Instagram photo by Victoria Allman • Jul 1, 2020

It would seem appropriate to say that this week’s XPM78-01 Möbius Progress Update is brought to you by the letter I as in Independence.  First, Christine and I want to send out our very best wishes to all our Canadian and American friends and family as they celebrate their respective July 1st Canada Day and July 4th Independence Day. 

All the more so given these extraordinary and challenging times all countries are facing right now.  Whatever your nationality, citizenship, residency or location right now we sincerely hope you are all finding ways to navigate this current storm and are staying strong, healthy and positive.

Thanks to Christine’s friend Victoria Allman for the fun Canadian fireworks flag image and to Tenor.com for the neat little GIF of the USA fireworks flag.

With each passing week, the progress that Team Möbius makes, while it  never seems to go fast enough, does move us closer and closer to our very own Independence Day when Möbius splashes at last and we return at last to a life afloat and at sea which is THE best form of independence which Christine and I have ever known.
Here at Naval Yachts, as June passed into July this past week, we saw a bit less progress than usual as several members of Team Möbius were pulled away to work on other boats in the shipyard.  However progress was made in every area that did get worked on so we still have lots to show you and let’s get on with that now.


IMG_20200703_183047Seems only appropriate to start of this week’s Progress Update with our very own “Sparkies” aka Electrical Team of Hilmi who is now has Selim working with him on wiring.  Hilmi was one of the team who was called away to work on other boats this week but for the three days he was working on Möbius with the added bonus of having Selim’s able hands to assist, good progress was made.

IMG_20200703_183056Down in the Basement here with the Main DC Distribution Panel which is continuing to fill up with cables large and small.  The astute will notice eight large cables coming out of the sealed battery compartments in the foreground here through that large oval penetration which will eventually be fully filled with special sealant to make it completely waterproof

This week they have been working on the BIG cables at the very heart of our Battery Based boat; the House Battery Banks and the cables which connect the 24 FireFly L15+ 4V @ 450Ah to the bus bar and shunts in that Main DC Panel on the Left here.  These Red/Positive and Black/Negative cables are eXtremely large at 120mm2 or “five aught” 5/0000 AWG size each which is about the size of a good sized thumb.

XPM 6S4P House BatteryThere are four individual 24 volt battery banks, each consisting of six 4 Volt @ 450Ah cells connected in Series, which is abbreviated as “6S”.  Thus their voltages are all added together to create a 24V @ 450Ah battery bank and then these four banks are wired in Parallel so their Amp Hours are all combined to create an overall House Battery Bank of 24V @ 1800Ah or 43.2 kilo Watts. 

XPM Electrical System w 4 Batt BanksHence the big cables to carry all those amps with as little voltage loss as possible.

I’ve put together these two schematics for those interested in some of the details of the House Battery Bank setup and the overall Electrical System on the Left here.
IMG_20200703_183750As per the reminder in this Victron Installation Guide for the three Victron BMV712 Smart Battery Monitors, it is very important that the lengths of each of the cables connecting the battery banks to the negative side shunt and the Positive Bus Bar be the same length.  This is something I see missed on many boats and it creates problems over time as the voltage drop will be different if the cable lengths are different and this leads to battery imbalance which can shorten their lifespan.
IMG_20200626_100458Last week, Selim & Hilmi connected all these battery cables to their respective terminals inside the Main DC Distribution Box as you can see here. 60mm x 20mm Positive Bus Bar running horizontally across the top and same size for the Negative Bus Bar on the  bottom.  High amperage T-Class fuses visible on the Positive Bus Bar, two Remote Battery Switches with their Yellow manual knobs visible in the background.
IMG_20200624_125335Barely visible in the photo above on the bottom Right end of the Negative Bus Bar, they have also mocked up the layout for the three Shunts that provide all the data to the BMV712 Smart Battery Monitors that tracks volts, amps, battery temperature and uses this information to calculate SoC State of Charge, Amps In/Out, etc.  The final installation will use properly sized copper bus bars for all the interconnections between the Shunts and the Negative Bus Bar.

IMG_20200703_184053With all the cables terminated on the Bus Bars, Hilmi & Selim have routed them down through that large oval penetration you can see in this and the photos above to take them inside the three WT battery compartments which are integral with the hull and sit on either side of the massive Keel Bar than runs like a spine from Bow to Stern.

This makes it easy for them to layout all six of these big cables to determine the length of the furthest connection/longest cable and then they can cut all of them to this same length.
IMG_20200704_131429I laid out the tools of the trade here and those tiny little Red wire cutters make quick work of cutting these huge cables cleanly in one go.  Then the Blue hydraulic swaging tool is used to crimp the copper lugs to the hundreds of strands of thin copper wires that make up each cable.
IMG_20200704_131347With the lugs fully crimped on each one gets an additional layer of shrink wrapped insulation which is lined with adhesive that melts with the heat used to shrink each tube and creates a permanently sealed cable connection.  There will be a T-Class fuse at each Positive Battery post so the Z shaped 30 x 5mm copper bars will attach to the battery post on one end and the fuse on the other and then the cable lug bolts to the other end of the fuse.
IMG_20200704_175705Time ran out for this week so this is where the cables are now and next week I’ll show you what it looks like once all the cables and fuses are attached.

Once all the batteries are connected to the Main DC panel, a rather exciting milestone will be looming on the horizon; Möbius will have power!
IMG_20200629_124008Moving back to the Aft end of the Workshop, they have also been working on the 24 volt power cables going to the two Accu-Steer HPU400 hydraulic steering pumps.
IMG_20200703_121311These are very powerful continuous run pumps that can draw up to 60 amps so they require some very large power cables to bring a steady supply of those amps all the way from the DC Distribution box up by the Day Tank.
IMG_20200703_182547Fairly straightforward job and Hilmi soon has it all buttoned up with the labels covered in clear heat-shrink which should help them last for decades.  As those of you who have done any amount of electrical work on your home, car or boat can attest, it is SUCH a big help to have every wire fully and clearly labelled so this is a very important “little detail”.


IMG_20200629_124039Cihan our super industrious Plumber was also in high demand this week but he was able to get a lot done in the two days he was working on Möbius.  Quite an exciting milestone as he was completing the installation of these two large Vetus Sea Water Strainers coming off of the big Intake Sea Chest in the front Starboard/Right corner of the Engine Room.
IMG_20200629_124109The pipes coming out of the Sea Chest are all thick walled aluminium which have those two huge PVC Blue handled Ball Valves mounted with flanges in between them and their entry into the bottom of each Strainer.  However, Cihan switched over to 316 Stainless for the outlets from the strainers which T into becoming the manifold. 
IMG_20200629_124056These SS Ball Valves in the foreground give you the reason for the switch to SS for the manifold so that the entire manifold is all 316 SS and there will be no problems with corrosion due to dissimilar metals.  You can manage SS to AL joints with isolators and anti corrosion paste but using all SS makes for my favorite kind of maintenance: NONE! Smile
IMG_20200629_124121Cihan had our talented machinist Yunus machine the Stainless Steel flanges that bolt to the composite bodies of the Strainers and once he had them in position, Cihan could tack the SS pipes in place.
IMG_20200630_115302Cihan works VERY quickly and I didn’t get back to the Engine Room in time to get a shot of all the SS nipples tacked to the body of the manifold but this is what they soon looked like when they were all fully welded in place and cleaned up.

IMG_20200630_115313These two large SS Ball Valves on the Left end of the manifold are for the Sea Water pump for the Gardner and our Fire Hose setup. 
IMG_20200630_115326These three smaller Ball Valves on the beginning end of the manifold supply sea water to the AirCon Chiller coolant pump, the Delfin Watermaker and the Aft Deck wash pump.
IMG_20200701_095016Looking into the ER from the entrance door this is what the whole Intake Sea Chest, Strainers and Manifold system looks like.

IMG_20200701_122835Looking straight down into the Engine Room from up atop the Aft Deck this birds-eye view makes it easy to see the layout of the whole Engine Room.

If you are wondering what that big gaping space is in front of the Red bundled up Nogva CPP Servo box is, that is Mr. Gee’s soon-to-be new home!

Bottom of this photo is the forward WT Bulkhead with the Guest Cabin on the other side.  Entry door into the ER just visible in the Upper Right corner and the Exit Sea Chest on the bottom Right.
IMG_20200701_122848And for a bit more orientation this the view looking forward at that big Hatch in the Aft Deck looking down into the Engine Room.  The ER Vent Box on the Left will double as one half of our Outdoor Galley and will have a SS sink set into its Turquoise marble countertop.  There is a near identical Vent Box on the Right side of the Hatch hidden from view by the Hatch Lid and this one will have more marble counter with the electric grill/BBQ set into it.

Spiral staircase up to the SkyBridge visible in the upper Right corner and the WT Entryway Door into the SuperSalon is visible behind the Left/Port Vent Box with the Galley on your Right as you go down those stairs.

Almost starting to look like home!


IMG_20200629_124514Speaking of Galley and looking like home, Captain Christine (and me too!) were excited to see this show up in the Galley this week.  Christine is a researcher par excellence and she spent a LOT of time researching all the equipment for our Goldilocks Just Right, Just for Us Galley and settled on this awemazing “smart” induction cooktop by Bosch, complete with that built in extraction fan system in the middle.
IMG_20200629_124700I will be able to show you more details as this gets installed but if you look closely inside that rectangular opening above my fingers (click to enlarge any photo) you can just  make out a very large “squirrel cage” variable speed fan which pulls all the air and small children or pets, through the two large slots in the AL vent you see in the photo above. 
This connects to a large 150mm/6” round duct in the cabinetry behind the cooktop which channels the air up to this second extraction fan mounted inside the Lower Wing box just aft of the top corners of the Galley and SuperSalon and puts all the extracted air out onto the Aft Deck.

IMG_20200630_144949For even more air extraction power when needed, there are two of these large axial fans feed by the Rosewood grill you see here in the Soffit Ceiling panels at the Aft end corners of the SuperSalon which help keep the breezes flowing from front to rear of the SuperSalon.
IMG_20200629_142548Below that extraction air grill Selim is finishing the Rosewood Nosings for the Entryway stairs.
IMG_20200629_142429In addition to looking AbFab these Nosings provide the Goldilocks just right amount of a lip for your feet to sense and prevent any slipping.  Additional Safety, one of our primary design principles for the XPM, comes from the indirect LED strip lighting that radiates from the underside of each nosing.
IMG_20200630_145020Looking straight up above the Entryway Stairs, Omur has finished the slightly tricky installation of this Rosewood Hatch Liner.  This Hatch sits to your Left when you are conning the boat from the Upper SkyBridge Helm station which is on the other side of the wall to the Right here.

The Black box is one of several alcoves for electronics.  This one will house things like a network switch, an N2K multi-port block and other components which feed the Upper Helm Station.
IMG_20200629_141836On the Galley side of these stairs there is a cavernous storage area which Selim is putting the finishing touches on here as he readies the Blum hinges for its door.
IMG_20200703_120613Moving into the Galley itself, can you guess what these two Ro$ewood beauties are for?
IMG_20200703_120619That was an easy one, they are two of the ten doors on the Galley countertop Garages.  Omur is now fitting the recessed invisible hinges.
IMG_20200703_121110I’ve used these type of hinges in many of my past cabinetmaking and jewellery boxes and they are the Goldilocks solution when you want an extremely rigid hinge that is completely hidden from view.
IMG_20200703_160304Having done all the hard work of mortising the slots for these invisible hinges when he was first building these Garages, it only takes minutes for Omur to screw each hinge into their respective slots.
IMG_20200703_182834Et Voila!  Nothing but Rosewood, glass (soon) and marble, not a hinge to be seen.


IMG_20200701_182633Fortunately both Selim and Omur were working onboard Möbius the whole week so they made great progress on cabinetry throughout the boat so let’s go check out what they were working on in the Master Cabin.

Any guess why these boxes are eXciting for me to see arrive?
IMG_20200701_182645Yup!  Fresh off the plane from Austria, these are all the undermount drawer slides for all the many drawers we have on Möbius.  Like the hinges you saw above these full extension drawer slides have zero sag even when drawers filled with heavy items are pulled all the way out.  They also become invisible once they are installed as they mount on the underside of the drawers.  These slides also have Blum’s “Servo Drive” which push them into your fingers with an initial push and then soft close when you push and let go.
IMG_20200701_182653Being that our home is very “mobile” we will also have positive mechanically locking latches on every drawer and door but these Blum slides also use these nifty locks to keep all the drawers securely closed.

OK OK, so I’ll stop obsessing but trust me, you’ll be impressed too when you try out Blum hardware.
IMG_20200701_182535More beautiful Blum goodness here in the Master Head/Bathroom “medicine cabinets”. 

Now you see ‘em…………………….

IMG_20200701_182518…………………. now you don’t!

Are you sensing a theme here?

IMG_20200703_160217One last bit of hardware happiness for you with a feature that may be new to many of you.  These Blum hinges also have a very handy soft close feature that is now adjustable.  See that little black button just above my thumb?  That allows you to set the little soft close spring on that lever to the Left of my thumb to be either Off or On.  With two or more hinges on any door this gives you a full range of degrees of “anti-slam” soft closing by turning on any number of soft close hinges for that door.

OK, enough for today’s tour through Hodgins Hardware Heaven.

IMG_20200704_101454Omur and Selim were busy installing these latch catches on the bottoms of these drawers in the Master Cabin.
IMG_20200701_182427Which will soon be installed in these four spaces in the Bureau of Drawers on the Stbd/Right side of the Master Cabin.
IMG_20200701_182504With the sloping hull sides behind this Bureau the two lower rows get a bit narrow so these will have down opening doors rather than drawers.  All these drawer and door fronts will be covered with Green leather panels to set them off nicely from the solid Rosewood edging.
IMG_20200701_182357Forward of the Bureau of Drawers is this bank of tall cabinets.  As throughout the rest of the boat, the Blue Horizon Line or BHL Handhold wraps around the room and all the vertical surfaces below this “horizon” are Rosewood and all above are Green/Gray leather.

The two Upper cupboards on the Right are Wardrobes for hanging clothes and the third one with the Vigo sink in it will soon have the Bosch Washer inside.  The last upper cupboard is sized for a matching dryer if there should ever be the desire to have one but we have always preferred to use Mother Nature as our clothes dryer since we were children and continue to do so.


Main Helm layout by YesimUpstairs from the Master Cabin, Omur and Selim also made some more exciting progress as they worked on the cabinetry for the Main Helm so let’s go up there now.

Yesim’s quick render above helps to show the overall layout with the two 19” touch and daylight readable monitors in the middle, the angled “dwarf wall” on the right of where the Llebroc Helm Chair will be and the two triangular “handkerchief” storage areas on either side.


And here is what the real world version looked like at the start of this week.
IMG_20200629_113750Selim gave me a hand to test fit this first mock up of the Zig-Zag dashboard we think will work really well. 
IMG_20200629_113817It has this narrow “kick-up” where the monitor mounting board will hinge.
IMG_20200629_113933So that the base of these monitors will set down at an angle like this.
IMG_20200629_180554I am going to KISS or Keep it Simple & Safe by panel mounting the two monitors into a Black leather covered mounting panel that will be hinged at the bottom edge so we can change the angle to eliminate any reflections as well as swing it down anytime we need to access any of the connections on the back.
IMG_20200629_112845Of which there are plenty for these eXtremely high spec monitors that we can hardly wait to start using.
IMG_20200629_113857As you can see here, all those cables will be fully hidden and kept out of any UV coming through the front windows and yet be low enough that they don’t block any of your line of sight when standing or sitting in the Helm Chair as their top edge is kept very low.  We also tested this setup and angles for any reflections in the surrounding glass and were able to eliminate them by this placement.
MVIMG_20200703_094842Omur had my little sketch of the Monitor mounting panel above turned into reality and all corners radiused, sanded and taken over to the Upholstery Shop.
IMG_20200703_162334Where the Black leather was stretched over and glued in place.
MVIMG_20200703_162508Ready to be trimmed and then have the monitors mounted inside.
IMG_20200701_182759Back onboard, Omur had the Zig-Zag dashboard all glued up and test fitted with its SS piano hinge.
IMG_20200701_182753Which makes it easy to unlatch and lift up to access wiring and the manual hydraulic steering pump underneath.
IMG_20200701_182740For any longer term maintenance of more likely trying out new Helm configurations, the whole dashboard can be swung up completely out of the way and exposing the whole back side where the electronics and wiring will be.
IMG_20200702_114421With the Monitor mounting panel in place on its hinges you can start to get a feel for the whole Helm.

IMG_20200629_124902Another example of all our work at modeling and designing this critical Helm space is this little angled wall on your Right as you sit in the Helm Chair.  Plenty of space inside for cabling and electronic goodies.
IMG_20200629_141303Which cleans up rather nicely when you snap the top into place.
IMG_20200630_143224Alas though, that beautiful top was not to last for long.
IMG_20200702_095127Sadly and feeling almost sacrilegious in doing so, Omur soon had that beautiful Rosewood top panel cut out for all the switch boards which fill most of this surface.
IMG_20200702_114732As you can see here.
IMG_20200701_183535This is for another boat that Naval is building but will give you an idea of what the switch panel will look like that fills those two lower cut-out in the photos above.
IMG_20200630_143221And now the real fun begins laying out all the components to be installed on the Dashboard.  Fortunately Christine had taken charge of this layout and had it all mapped out for the major components you see here. 
Working to the Left from the bottom Right corner; Kobelt Throttle & CPP Pitch controller with round Pitch Gauges hidden behind, Furuno NFU Jog Lever, Furuno 711C AutoPilot head.  Top Right corner is the ACR 360 degree Pan/Tilt searchlight joystick.  Not seen here but to the Left of the ACR joystick will be the Bow Thruster Joystick and the Maxwell Anchor Windlass controller.

IMG_20200630_144255Thanks to all of Christine’s planning and drawings, this “meeting of the minds” with Yusuf the lead Sparkie in the foreground, Hilmi in the back and the man in black, Hakan our Master 2D cabinetry CAD man on the Right all went well.
IMG_20200630_143216And we soon had the basic layout in place.
IMG_20200703_095120Omur and I spent a few minutes doing the exact layout to get the size and location of each cut-out just right and he soon had those all cut, sanded and the Dashboard headed over to the Upholstery Shop on Friday to receive its Black Leather covering to match the Monitor Panel.

Mr. Gee:

Last but never least, while I didn’t get much time to work on him directly I spent a lot of time this past week finishing the designing of the six mounting brackets for the anti-vibration mounts for Mr. Gee and his partner in propulsion, the Nogva CPP Controllable Pitch Propeller Servo Gearbox. 

Gardner & Nogva mounts screen shotIf you have not yet seen last week’s Progress Update you may want to go back to it now for a more detailed coverage of those mounts and brackets and this is the basic layout of the Port/Left side mounts on the sloping 25mm / 1” thick AL beds welded into the Hull.  Two forward mounts are for the Front & Rear of Mr. Gee and then an underhanging bracket for the mounts on the Red Nogva CPP Servo Gearbox.  Stbd side is the same.

IMG_20200629_105639Once I had the design fully modeled and triple checked for accuracy and fit, I printed out a set of drawings for Uğur to start cutting the 25mm/1” thick AL plate these mounts are all made from and he soon had this pile of gleaming aluminium parts on the bench.
IMG_20200701_094929Being so thick, you need to have very deep V shaped grooves where the plates join and will be welded so as to get full penetration of the weld and basically end up with a single piece of aluminium.
IMG_20200701_143430This is the Right Rear mount on Mr. Gee and they need to fit quite precisely so Uğur and I spent several hours going back and forth fitting each plate that bolts to Mr. Gee.
IMG_20200701_143255I extended this Front Left plate aft about 300mm/12” in order to provide a mount for the Jabsco Sea Water impeller pump so it required a bit more work to cut in all the notches to have it clear all the bosses on the solid aluminium cylinder block of Mr. Gee.
IMG_20200701_164955My workshop/Office and Mr. Gee are all up on the first floor of the shipyard and it didn’t seem to be worth it to drag a welder up there so Uğur and I made lots of trips up and down while tacking up each mounting bracket down on the shop floor below Möbius and then bringing it upstairs to test fit and measure alignment on Mr. Gee.

This is the Rear Right mount and it is now fitting just right.
IMG_20200701_165239Left Rear mount is a mirror image of the Right side and we soon had it all tacked, aligned and ready to be welded.
IMG_20200702_100512Moving on to the Left Front mount with the extended base plate for the Jabsco pump we positioned each piece to the lines we had scribed into the aluminium while they were clamped in alignment to Mr. Gee upstairs.

on the Left here is the original Gardner mount which I was going to reuse but it had stress cracks in the corners, one of which you can see on its far Left corner where I ground it out to weld.  However these are cast aluminium and the new welds just cracked soon after being applied due to the different expansion rates between the cast AL and the AL welding rod.  Hence the decision to design and build all new brackets.
IMG_20200702_103859Uğur and I have worked well together since we began this build over two years ago and we continue to enjoy doing so and soon had that Front Left mount all tacked up and fitted.

IMG_20200702_103849If you are wondering what the big holes are for, the PTO Power Take Off on Mr. Gee which is that cylinder you see to the Left of the mount, will soon have a drive shaft coming off of it to turn the Jabsco impeller pump and hence the holes for this shaft to fit through  If you look again at the original Gardner front mount in the previous photo you will see that it has the same hole in it as Gardner used this PTO to drive their alternators.
IMG_20200702_103904Here is the shaft’s view through those holes to the PTO.
IMG_20200702_103600The Front Right mount is much simpler and this is one of the anti-vibration mounts that we are using to check heights and fit before welding.
IMG_20200702_124327All four mounting brackets all tacked and ready to be fully welded into single solid motor mounts.
IMG_20200702_143914As usual, it is all in the prep work and the actual welding goes very quickly.
IMG_20200703_121427Uğur was only available for three days this week but by Friday he had all the mounts welded and ready for me to clean them up, do the final fitting and filing and paint them.
IMG_20200702_182826Here is a good example of how those big V grooves allow the first weld to fully penetrate these thick plates.
IMG_20200702_182814Then the second pass fills in that U shaped groove from the first weld and leaves you with a flat and solid top weld.
IMG_20200702_183550Same routine for the Front mounting brackets.  L-bar on the Right one still in place to hold that vertical piece perpendicular while being welded.
IMG_20200703_164427By Friday noon, a justly happy and proud Uğur could pose with this Rear Right mount all done and in place on Mr. Gee.
IMG_20200703_182419All four mounting brackets all welded up and I think even Mr. Gardner would approve.  I then spent Saturday morning cleaning them up, putting good radii on all the edges, chamfering all the bolt holes, etc. and had them all ready to be painted.
IMG_20200704_175359I sprayed them with the same silicone based “liquid aluminium” paint to match what I used on Mr. Gee himself.
IMG_20200704_175421And this was the final result.

Tomorrow (Monday) I’ll get busy bolting the to Mr. Gee and he will be all the more a “real boy” as per last week’s Jiminy Cricket reference and able to stand on his own four feet!
And before I seem to blink twice, another month zooms by and we are already a week into July!  How is THAT possible??

In any case, hope you enjoyed this week’s Show & Tell and that all our Canadian and American friends enjoyed a safe and well distanced Independence Day.

Thanks for joining and be sure to leave your comments and questions in the “Join the Discussion” box below.

See you next weekend.



Yes, We’ve Lost our Marbles AND Now we have MUCH More! XPM78-01 Möbius Weekly Progress Update June 22-26, 2020

Summer has definately arrived here in Antalya Turkey and it has been a glorious week both weather and progress wise on XPM78-01 Möbius at Naval Yachts.  Our daytime highs are now all in the low to mid 30’s (85-95F), the huge outdoor pool at our apartment is filled and open and we have a lovely breeze blowing through our 9th story apartment pretty much all the time.

You’ll need to scroll way down if you really need to know what this week’s title reference to marbles is all about but for now let’s jump right into this week’s Show & Tell of all the progress Team Möbius has made this past week of June 22-26, 2020.


Master Plumber Cihan, sporting his new post-Covid haircut was his usual productive self this past week so let’s catch up wtih some of his work next.

IMG_20200624_164653He spent some of his time crammed into this very busy Aft Stbd/Right corner of the Basement where a LOT of his previous work installing all the many hoses for Fuel, Potable, Grey and Black Water meet up. 

IMG_20200624_125216Exiting Sea Chest in the middle foreground in the above photo where this Medusa like collection of clear hoses now attached to the Flute style manifold. 

Here is a better view of all the hoses underneath of Cihan in the first photo above.  Black two no the Right are Fuel Fill & Vent lines, flanked by two large White hoses for the Grey Water tank below.

White hose going into the side of the Sea Chest is for emptying Black Water Tank.  Large Grey PVC pipe up on the ceiling are Extraction Vent Ducts for the Battery Compartments and the Basement.
IMG_20200625_094803White tank just visible on the Right above and here on the Left, is a 150L / 40USG emergency fresh water tank that is completely independent of all the 7100L / 1875UG of Fresh water in the integral hull water tanks.

Cihan has this tank plumbed to be filled from the main Fresh Water manifold on the output of the 150LPH / 40GPH Delfin Watermaker as is the case for ALL our built in fresh water tanks that are built integral to the aluminium hull framing and hold a total of 7100L / 1875 USG.

The tank is then plumbed to a second Cold water only faucet on the Galley Sink which sits directly above this aft Stbd Basement corner.
IMG_20200625_124941Back in the Workshop Cihan was busy installing this SS sink in the Workbench on the Aft Port/Left side.
IMG_20200625_124944Wherever possible we use PEX tubing and fittings like these for all our water lines as it is SO superior to anything else.  Easy to work with and route, continuous lengths with no joint or connections, push-on fittings which in my experience almost never leak and all plastic construction so no corrosion issues.
IMG_20200626_095851Sink now sealed into the Workbench with Blue PEX tubing all ready for installing the Cold water lines.  Faucet installed and ready for connections.
IMG_20200626_095856Drain lines installed, Hot & Cold SS lines ready for their connections.
IMG_20200626_095930Here is where this Sink is located back near the air compressor and the sides of the HazMat locker.
IMG_20200626_170039More PEX goodness with these simple manifolds built from Push-On PEX valves and T’s.
IMG_20200626_170045Following the Blue/Cold PEX tube and the Red, now sheathed in Black EPDM insulation foam, you can see how easy PEX tubing is to route.
IMG_20200626_170057The H&C PEX lines continue forward to this tray where they turn 90 degrees to run across the ceiling overtop of the walkway in the front of the Workshop to the WT Door into the Corridor.
IMG_20200626_170111The go through this penetration at the top of the ER Enclosure on their way to that vertical penetration you see in the background where they will go up to the other SS Sink in the Outdoor Galley inside the Port/Left Vent Box.
Aft Deck Vent Boxes Galley labeledLabeled layout of the Outdoor Galley to help visualize this area.

Primary purpose of these two Vent Boxes on the Aft Deck is to provide ducting and Mist Eliminators for the Supply & Extraction Air for the Engine Room and Workshop but we also used these as the foundations for the Outdoor Galley.
IMG_20200626_140708Adding all the hoses for the sink water and drain along with the drain for the Mist Eliminator requires some new access holes be cut into the Sink compartment on that Port Vent Box. 
Cihan is at least as highly skilled in aluminum work making all our brackets and access ports so he made short work of cutting in the new access ports for these water lines going In/Out of the Upper Front compartment of this Port Vent Box.

IMG_20200626_172943This allows him to bring the Hot & Cold PEX lines up to the faucet on the Sink that fits into this compartment.  Each PEX line has its own Push-On shut off valve on each end and the hoses from the faucet will connect to these.
IMG_20200626_172924Not to be left out, this small Blue drain pipe from the Mist Eliminators in the ER Intake Air vent will cross over through that round penetration on the Left and ………
IMG_20200626_172952 …….. join up with the Hot & Cold PEX lines over here under the Outdoor Galley sink going down into the Engine Room which you saw up in the photos above.
Port Vent   Sink Box labelledThe interior of this Port Vent Boxes is divided up into four compartments and it gets a bit busy in here with all the various bits and bobs of plumbing, ducting, sinks, etc. so I thought this labeled shot of the Upper Aft compartment of the Port Vent Box might help keep things straight.
IMG_20200626_184225Switching from water to hydraulic fluid/oil, Cihan did a great job of running the 28m/60’ of hydraulic hose it required to get from the Accu-Steer pumps at the very aft end of the boat up to this area below the dashboard of our Main Helm where they connect to this Kobelt manual hydraulic steering pump.

The Black Block in the background upper Right corner is for the connection to the small header tank that mounts up inside the Helm Station upper Right corner.

IMG_20200622_180124This manual steering pump has a traditional steering wheel which we can slide onto the SS shaft you see here just in case we should ever experience complete loss of ……
IMG_20200622_180500……. our doubly redundant Accu-Steer HPU400 powered hydraulic steering pumps which Cihan has also pretty much finished plumbing.

Aluminium Work:

IMG_20200619_183918Let’s start with the first Quiz Question for you;

Can you guess what these new aluminium pieces that Nihat and Uğur are working on will become?
IMG_20200622_103720We will soon have these aluminium stairs to get In/Out of the Basement!  Up to now we just had a set of makeshift wooden stairs left over from another job which worked well enough but these new aluminium ones will be much steadier and easier to get in and out.
IMG_20200622_133939Uğur soon has them all welded and cleaned up and bolted in place up at the top.  He also added some nylon “shoes” on the bottom to keep them quiet where they sit on top of the Battery Compartment lid.
IMG_20200622_150501Everyone on Team Möbius gave them a quick test and thumbs up all around.
IMG_20200622_175806Seen from directly up above you can see how they sit.  Normally there will be an aluminium hinged lid with a gas assist strut and the finished flooring on top so you won’t even know this hatch is there but a quick pull will open up the lid and let you safely climb in and out of the cavernous Basement whenever needed.
IMG_20200626_141051With the stairs all done they quickly moved on to the next aluminum item on the To Do list.  Any guess what this 25mm thick AL plate they have just brought over is about to become?
IMG_20200626_165736Uğur starts cutting out the different shapes which might give you some clues but this is a tough one to guess at I think.
Gardner & Nogva mounts screen shotThese are the mounting brackets for the six anti vibration mounts, two on either side of the front and two on the rear of the Gardner engine which is not shown here and will be on the Left.  Then two for Left/Right side of the Red Nogva CPP Servo box. 

This is a quick screen grab from the Fusion 360 3D model I created while designing each of the six mounting brackets.  Just showing three Port/Left side mounts and brackets here.

The two sloped 25mm / 1” thick Beds you see top and bottom run lengthwise down each side of the Engine Room as part of the hull and the six flexible motor mounts will connect to each individual mounting bracket bolted to the Gardner and the Nogva CPP.
Front   Rear Gardner mounting brackets screen grab

Zooming to show the Front Gardner bracket on the upper Left which bolts to the front side of the Gardner and then the Rear Gardner mount on the Right.
Front Gardner mounting bracket screen grabLooking at the other side of the Front Gardner bracket to show the added extension to the Bed for the flexible motor mount to bolt to and the additional 25mm vertical gussets I’ve added below to ensure this is rock solid.
Nogva mounting bracket screen grabAt the aft end the flexible mount for the Nogva serves double duty being both a mount to share the load of the overall Gardner/Nogva solid assembly as well as being a thrust bearing to deal with the fore and aft forces transmitted by the propeller shaft as it drives the boat forward and reverse.

As shown here, this bracket needed to be designed to fit below the Beds to provide a solid Base Plate for the mount to bolt to.
IMG_20200626_165807My hand will help give you a sense of size and scale of these pieces, this one being the vertical gusset for the rear Nogva mounting bracket.
IMG_20200626_184508As you can see in the model, I’ve kept the shapes all very simple geometry so Uğur had all the individual pieces cut in a few hours on Friday afternoon.

Mr. Gee:

Mr. Gee Fuel Injection pump unpacked on workbenchDesigning all these mounting brackets took up most of my waking hours this past week as the tolerances are pretty tight and I had to get them all just right so I didn’t get any time to work on Mr. Gee himself BUT I can give you a sneak peek at this beauty which I unboxed for the first time since it arrived direct from Gardner Marine Diesels. 

I’ll leave you to ponder just what this strange looking contraption is and tell you all about it next week.


IMG_20200622_101211Our lead Sparkie/Electrician Hilmi was as busy as ever this week too.  Seen here and below he has added four more of the little Black LED dimmer controls ……..
IMG_20200622_101227………….. inside the lighting junction box in the Upper center here inside the Guest Cabin.
IMG_20200622_175826Down in the Basement inside the Main DC Distribution Box he has mocked up this layout for the three Shunts that connect to the three Victron BMV712 Smart Battery Monitors which are so critical to a Battery Based Boat.

Now that the layout is finalised Hilmi can now replace the two copper tie strips with full size 50 x 10mm copper bars to provide the necessary ampacity for the 900 Amps from Bank A & B and the total 1800 Amps connecting to the Main Negative Bus Bar at the bottom.

XPM Electrical System w 4 Batt BanksWith thanks to several of you who pointed out typos this is the basic schematic of the overall Electrical System on XPM78-01 Möbius where you can see how these three Shunts connect.
IMG_20200626_100447Hilmi spent quite a bit of time this past week installing all these Red/Pos & Black/Neg cables coming in/out of the Main DC Distribution Box where they connect to either the Lower Negative or Upper Positive copper Bus Bars or to one of the many rotary switches.
IMG_20200626_100508As with the other Distribution Boxes this Main one in the Basement is quickly filling up with all the individual cables, switches, fuses, circuit breakers and remote relays.
IMG_20200623_094812The last and perhaps most exciting jobs that Hilmi worked on this week is all the indirect LED lighting strips that go into the toe kicks underneath all the cabinetry and some up along the Blue Horizon Line BHL Handholds throughout the boat.
IMG_20200623_110936The colours are way off due to the influence of the overhead work lights but you can imagine how great this will look at night and how much of a safety factor this will be whenever we are walking around on night passages with these all fully dimmed.

Every light on the boat is LED and all the interior lights are on full dimmers so we can have the Goldilocks just right brightness at all times.


Moving on to interior cabinetry let’s work our way from front to back starting with the Master Cabin.

IMG_20200622_101545As you may recall from past weekly posts Omur & Selim had finished the Rosewood Hatch Liners and this week they got round to installing them into the inner aluminium hatch frames.

This is one of the matched pairs over our Bed and you can see the one in the Shower & Head in the background.
Master Cabin rosewood hatch liner installedHere’s what it looks like when finished.
IMG_20200624_124559Same routine for this one overtop of the center Vanity sink at the very front of the Master Cabin against the front WT Bulkhead.
Master Cabin rosewood vent grillsAnother part you’ve seen being built in past weeks, these Ro$ewood vent grills are now in place on these two steps up to the landing on the Port/Left side of the Master Bed.  These two grills supply air to the AirCon/Heating Air Handler under that sits inside the cabinet on the Upper Left here.


IMG_20200624_164012Moving all the way back to the Guest Cabin these “hairs” can mean just one thing; the Guest Shower is getting glassed in.  Same method as they did in the Master Cabin Shower, the interior marine plywood walls first receive this first layer of fiberglass mesh and resin to fully seal and tie together the walls, ceiling and floor.
IMG_20200624_164030This creates the foundation for the next step which is to cover all these surfaces with thin 3mm thick sheets of fiberglass they have laid up in a mold in the Composite Shop with one surface being smooth shiny White gelcoat that becomes the interior finish.  Then corner joints are filled and sanded to a nice radius and the whole thing polished to a glass smooth finish.

We much prefer this built in place method rather than building the whole shower as in a mold in the workshop and then bringing that onto the boat as a large single piece.  Doing so requires that you put these shower and bathroom units in while the hull is being built and before the decks go on which in our case would have been almost 2 years ago.  Doing it this way, we can build them in place at this much later stage of the overall build when all the metalworking and other major construction dust is finished.


IMG_20200622_180333Up, up, up we go to the ceiling of the SuperSalon which Omur & Selim mostly completed this week.  These outer ceiling panels that form the Soffit that runs around the whole outer perimeter of the SuperSalon are now all finished and snapped into their FastMount fittings on the Black Soffit grids.
IMG_20200622_103607All of the ceilings above the Main Helm station at the very front of the SuperSalon are finished in Black leather to help reduce glare and reflections when we are on night passages so you peer thought the protective plastic covering which has a blue tint to it, you can make out that the forward three ceiling panels over the Main Helm itself and this Soffit Ceiling Panel are all Black leather.  The next row of ceiling panels extending over to the Left will also be Black Leather and then they all switch to White for the rest of the way back.
IMG_20200622_134548Omur came up with this nice L shaped edge treatment of the Soffit panels which adds a nice touch to the overall ceiling we think. 
IMG_20200623_132404The White sockets in the phot above are the female FastMounts where the matching male components here on the Left in this Soffit ceiling panels click into.  It is a very slick system that holds the ceiling panels very solidly and quietly in place and yet can be popped out in seconds anything you need to access what’s behind them.
IMG_20200623_132336The two aft most Soffit Ceiling panels have these Rosewood grills set into them for the eXtraction behind them to pull all the fresh air through from the front of the SuperSalon and out to the Aft Deck.
IMG_20200623_132322I wasn’t fast enough to get a phot before they upholstered these Soffit panels with their White leather and then covered them with protective blue tinted plastic but you can use a bit of imagination to see how these two aft corners will look when fully finished.

This grill is on the rear Port/Left corner with the Entryway Door out onto the Aft Deck just visible in the Upper Left.
IMG_20200626_165539Our lead upholsterer is eXtremely good and fast and here are a couple of sequenced photos I grabbed to show how he covers all those Ceiling panels. 

Hole in the middle is precut for the LED light that will be installed here and the holes around the outer edges are predrilled for all the FastMount pins to thread into.

IMG_20200626_165549The upside down White epoxy covered marine plywood ceiling panel is placed on top of upside down White Leather and the four corners are folded and fastened with SS staples using a very sweet little pneumatic staple gun.
IMG_20200626_165709Then pop! pop! Pop! before you can blink each edge is folded, stretched tightly around the edge and stapled in place.
IMG_20200626_165611Pop! Pop! Pop! Pop! Pop! Pop!

Rinse and repeat and one more panel is ready to be taken out to Möbius and snapped into the awaiting ceiling grid.
IMG_20200623_095136Selim has finished installing the Rosewood Stair Risers leading up to the Entryway Door.
IMG_20200624_100122Galley on the Left that we’ll be seeing much more of a bit later and the reversed stairs leading down to the Guest Cabin, Ship’s Office and WT Door into the Workshop on the Right.
IMG_20200623_095157Up in the “doghouse” over the Entryway Door, the Solid Rosewood trim piece is glued into place.  The WT doorframe is all nicely brushed aluminium and provides a lovely contrast to the polished Rosewood trim.
IMG_20200623_094750Forward of the door in the Doghouse the Rosewood Hatch Liner is now in place.

Black corner box visible at the bottom here is one of several “alcoves” we have built into the interior that will house electronics such as network switches and hubs, NUC computers, N2K Multi-Port blocks, routers and so on.  I’ll show you more of these as they are installed.
IMG_20200623_094755Stepping a bit further Aft on the deck will give you a better perspective on this Doghouse on the inside of the Entryway Door and how that Black corner block fits in.

For orientation, the Upper SkyBridge Helm is on the Left side of the Doghouse wall.

Inside, the Galley is on the Right, Main Helm Station at the far forward end of the SuperSalon.
IMG_20200625_183341Speaking of the Main Helm Station, the two triangular Rosewood ‘Handkerchief” lids on either side of the Helm area are now installed.
IMG_20200625_183348Flip up lids reveal a LOT of storage space underneath with removable bottoms to access cables and such inside.
IMG_20200625_183429Same setup on the opposite Starboard side of the Main Helm above the stairs leading down into the Master Cabin.  We think these two storage areas will provide easy access to things like binoculars, notebooks, charging stations, laptops, pens & pencils, and the like.
Main Helm layoutThis quick render by Yesim several months ago will give you an idea of how the Main Helm area forms the front of the SuperSalon.
IMG_20200625_183441Taking a step back in the real world, if you can mentally block out all those cables with a nice Black leather covered dashboard angling up to the base of the center window with two side by side daylight readable 20” touch screen monitors, you can visualize what this Main Helm Station will look like.
Main Helm side wall top glued upAnd Omur now has the removable “lid” for that sloped Helm Wall all glued up and it is now up in the Finishing Shop getting its many coats of PU varnish all rubbed to a satin gloss so that should be in place for me to show you next week.


Every week seems to have things that excite us but this week was all the more so true with what you can read in the other posting about getting Möbius officially registered and flagged in Jersey.  AND we also saw another new milestone in our Galley that we are eXcited to show you now.

IMG_20200623_132600Of course I’ll need to keep you guessing for a bit longer so here’s your first clue about the eXcitement that’s been cooking up in our Galley this week.

These special tools were involved.

Oh, and your second clue is in this week’s title.

IMG_20200623_132637More tools of the trade involved here; a diamond saw.

How about if I add the final clue that you are looking right at it?

IMG_20200622_173339As are Omur and Selim in this photo as they unpack the first few slabs from their wooden crates in the background.

Yup, time to start cutting and fitting the awemazing slabs of this Turquoise marble our fabulous Interior Designer Yesim found for us. 
IMG_20200622_173344Yesim has been mostly working from home the past few months as her job works very well for that but she came in a few days this week to help organise and oversee the beginning of the marble work.
IMG_20200622_173754The majority of the marble is in the Galley and these are most of the slabs laid out in approximate position of the countertops.  Omur in the bottom Right is kneeling about where the induction cooktop will sit, Selim in the bottom Left corner is where the “peninsula” sits alongside the walkway as you come down the stairs from the Aft Deck.

Yesim is where the L-shaped settee will be.

IMG_20200623_132645The biggest cut-out by far is for our big double SS sink so that was the first order of business which the diamond blade you saw in the clue above made quick work of.

IMG_20200623_132904The slabs arrived from the quarry cut to widths and with some edges already having their bullnose edge ground and polished but the smaller details are now being done here in house.
IMG_20200623_132813The first batch of stone that arrived had some cracks and other defects so Yesim worked with the stone company who were great about it and sent us pretty much an entire new order so we have lots of these beautiful marble slabs of all sizes to chose from and find the Goldilocks just right combination of grain and colour to match together.
IMG_20200623_133045Selim & Omur have been working for the past month at cutting out these white templates in place atop the Galley cabinets to get the sizes, cut-outs and radius corners all just right and now our Marble Guy is using these to cut and trim each piece, do the cut-outs and radius the edges.
IMG_20200624_095530He does as much work as he can down on the shop floor to keep the marble dust down there and here is is doing the final shaping of the large radius on this corner and the smaller one on the Left.
IMG_20200624_095930Pretty soon though, they were able to gingerly carry the biggest single piece with the sink cut-out in it, up to the Galley and set it in place for the first test fit. 

The fit is a bit tricky as there are so many elements already in place that the marble has to fit in just perfect such as along all the edges of the Rosewood Garages like the long one you see here.

But the templates worked as they should and this first piece of marble fit Perfect!

IMG_20200624_124125As did this second piece that creates the countertop behind the L-shaped settee that will be on the far Left.

Christine and I are super happy with our decision to stop the Garage on this leg short to give us that nice big open portion of countertop on the end.  Will make it easier for passing things back and forth from the Galley to the Settee and for the food chopper to work just out of the way of the head Chef.

IMG_20200624_164147Work proceeded very quickly and Selim is busy checking that the underlying surface for the last piece is all perfectly flat and level before it is set in place.
IMG_20200624_165056Here’s that final piece of marble with the far corner now cut out as well as the rectangular hole cut in the opposite corner where some of the wires come up into the Garage for light switches.
IMG_20200625_094326Omur stays on top of everything throughout the whole process, here making sure that this last countertop is perfectly level and on the same plane as all the other countertops.
IMG_20200625_094508With the OK from Omur it is fastened down with adhesive and clamped in place so it doesn’t move while the put the awaiting Garage in place on top and pull the light switch wires through the chase inside the Garage.
MVIMG_20200625_155715With the wires pulled through the switch opening they can apply the adhesive to the Garage and clamp it into its final position like this.
IMG_20200625_155740Being sure that this big mitred corner is also just right and clamped into its final position.
IMG_20200625_155612Difficult to get it all into one shot but this will give you a bit better sense of what the whole Galley layout looks like with all the marble countertops and Garages now nestled into their new homes.
IMG_20200625_094543As you’ve been seeing all along I have a “thing” for well radiused corners on ALL edges which Omur knows well and so this is how it all comes together with the various levels and layers of Rosewood and Turquoise marble. 

Difficult and eXpen$ive  to execute? 

In the eXtreme! 

But views like this show the lifelong dividends this will return.

IMG_20200625_183123Test fitting the big deep double SS sinks which also fit in just right.  Christine tried this out on her weekly Friday visit and is delighted with the placement of these sinks which we debated for weeks.

Induction cooktop will soon be fitting into that open rectangle on the Right.
IMG_20200625_183102One last shot as I close out the week.  This shot will help you imagine the overall size and scale of things and how each area fits together.  L-shaped settee in the bottom Left and steps leading up to the Entryway door to the Aft Deck which you know well by now, on the far Right.
I will let all these photos speak for themselves and wish you adieux until next weekend when I’ll be back with the next progress update.

Hope you are enjoying following along as much as I’m enjoying taking you along. 

And even though I am woefully tardy in answering the past 2 weeks of comments, PLEASE do add your questions and comments in the “Join the Discussion” box below.  I WILL answer them and I do thank you for your patience when it takes me longer than I would like.


Floor to Ceiling Progress on XPM78-01 Möbius Progress Update June 15-19, 2020

We are eXtremely grateful to be continuing to enjoy both wonderful summer weather and full work weeks here in Antalya and at Naval Yachts this past week.  As per the title of this week’s progress update Team Möbius has been working on everything from floors to ceilings as you will soon see in this week’s update.

It is Saturday June 20th as I sit here writing this and we are under an unusual lockdown for the weekend where everyone other than students are asked to not go out between the hours of 9am and 4pm while all the students are busy writing their annual exams.  We’re not sure of the exact story but apparently the concern is that it has been typical in the past that lots of students and their families like to celebrate once the exams are over, which we can all relate to, and so they are trying to reduce this and people’s exposure for this weekend and next when there are more exams. 

IMG_20200620_134827[3]However for Christine and myself this is hardly any hardship and we welcome and applaud Turkey’s continued vigilance and caution to help keep their already low numbers to stay that way.  The apartment complex we live in has three 12 story buildings with only two apartments on each floor so it is not very densely populated.  I’ve just snapped the photo on the Left from our 9th floor balcony and as you can see the swimming pool opened for the season last week so we now have that to enjoy as well. 
Otherwise we are busy as usual working from home on all the “administrative” aspects of building a new boat so Christine has just successfully gotten Möbius officially registered and flagged and I’m focusing on designing and modeling the mounting system for Mr. Gee and the Nogva CPP propulsion system inside the Engine Room so that Uğur and Nihat can start building those on Monday morning.

So with that as a brief introduction please join me for a tour of all the progress that Team Möbius has made this past week.


IMG_20200617_183849We’ll start this week’s Show & Tell up in the Forepeak where Uğur and Nihat have been busy putting in the framing for the flooring in there.  Framing is a bit complex in terms of shape but simply made by welding lengths of aluminium L-bar around the perimeter of where the composite grate flooring will sit.

Standing at the Aft end of the Forepeak looking towards the Bow.  Exit Sea Chest on the Right, Chain Bin on the Left.
IMG_20200617_183906Standing in the front looking Aft at the WT Bulkhead with the Master Cabin on the other side. 
IMG_20200618_175028Nihat and Uğur are a great team and in no time flat they have all the L-bar framing welded in place, cut the composite grating cut to size and set into their frames.

The added step on the upper Left protects the large PVC ball valves that control the Black and Grey water exiting to either the shoreside pump-out or the Exit Sea Chest seen here in the bottom Left corner.

Black Water tank in the Upper Right corner, DC and AC cables crossing the WT Bulkhead in the cable tray up top and miscellaneous plumbing runs for Black, Grey and Potable (fresh) water below.
IMG_20200619_100404Climbing up onto the Foredeck and looking back down into the Forepeak to get this overall shot of the whole floor inside the Forepeak.  They also put in the little step in the lower Right corner which serves double duty to both protect the wiring in the cable tray underneath and provide a final step as you climb out which Captain Christine tested out yesterday and is VERY pleased to have.

The Forepeak is where we will store most of our ground tackle such as shore lines, fenders and the like so when we are anchoring or docking we access this area quite a lot and being able to get in and out quickly and safely was a top priority as we designed it and it is already eXceeding those design goals.
IMG_20200619_100420Looking at the Starboard/Right side you can see another way in which we have built in an easy and safe design for getting in and out by welding 40mm/ 1.5” pipe to the edges of all the longitudinal stringers in the Forepeak to create a build in ladder or set of steps to clamber in and out with great handholds the whole way.

Now having the additional grated first step at the bottom and that little one at the top you can just  see in the bottom Right corner here has really worked out well. 

When the stringers were first being CNC cut, we had all the little moon shaped cut-outs done create super secure hand holds everywhere and these also give us hundreds of perfect spots to hand lines, clip on fenders and tie things to.  This is going to be a fabulous space to work in and such a joy to have so much storage space compared to any other boat we have had.

IMG_20200618_175337While they were working up in the Bow and Anchor Deck area they also polished off another To Do list item by welding in the slats on the two fold up Dolphin Seats.
MVIMG_20200618_175341Uğur ran the testing program and gave it full marks as did Captain Christine when she came for her weekly Owners Inspection on Friday.  We will probably sew up some cushions that can be tied onto these for even more comfort and we can already imagine the joy of having these seats live up to their name as we watch our frequent Dolphin visitors frolic in our bow wave as they always love to do.
IMG_20200619_100506Moving back to the Port/Left Aft Deck they also quickly installed the last of the three eXtremely robust fairleads into the Rub Rails.  These are super helpful to run shorelines though and take them over to the huge Lewmar 65EST winch in the center of the Aft Deck. 
IMG_20200619_100513However most often we will use these two fairleads with Dyneema soft shackles tied to turning blocks for our Tender Davit Arch system.  More on that as we get to building it.


Making the transition from their aluminium work up at the Bow, Uğur and Nihat joined forces with Cihan the plumber down in the Engine Room to finish installing the two bit sea water Strainers on the large Intake Sea Chest.

IMG_20200619_173139Last week they had finished welding in the dual 70mm / 2.75” ID aluminium pipes coming off the Sea Chest with flanges for Cihan to now start mounting these two Vetus strainers.
IMG_20200619_173151Next week they will build and install the common manifold that both SW Strainers will T into and will run parallel above the long AL pipe closest to the ER wall. 
You can see the side outlet on the Right Strainer where the AL pipe connecting it to the manifold will attach.  Same flange comes out of the bottom Strainer towards the wall where it will T into the manifold.

IMG_20200619_174549Standing in the entry door towards the Front Stbd corner of the ER provides this perspective of how this all fits together. 

Mr. Gee will soon be mounted to the 25mm/1” thick Engine Beds running on either side of the equally thick center Keel Bar that runs the full length of the boat.

ER exhaust duct just visible in the Upper center with the curved Duct for the exiting air vent from the Workshop on the Left of it.

The two big PVC ball valves enable us to switch from a Sea Strainer that clogs to a new clean one with one simple 90 turn of one of those Blue handles.  Strong, Simple, Safe & Efficient, the priorities we design, build and sail by.


IMG_20200619_095751Cihan spent most of his time again this week putting in all the hydraulic plumbing for the Kobelt Steering system.
Kobelt steering hydraulic schematic 0093-Pi_RevAThis schematic from Kobelt in one of my former home towns, Burnaby/Vancouver British Columbia will let you see how all the Kobelt steering components are interconnected. 
All quite simple but takes some time and ingenuity to figure out how best to route and run all these big hydraulic hoses throughout the boat and Cihan is a wizard at doing all this.

IMG_20200618_182838Looking down the Stbd side steering cylinder where it connects to the solid AL Tiller Arm you can see what the reality of the schematic above looks like in reality.  These lines are the ones you see in the center of the schematic where the lines connect to #5 Safety & Bypass Valve.
IMG_20200617_095119Cihan has been getting his exercise going back and forth between Möbius and the swaging machine in the workshop as he makes all the high pressure hydraulic hoses like these with all their different end fittings.
IMG_20200618_182532Sitting atop the center Keel Bar Looking up at the underside of the Upper Rudder Shelf to get this overview of how the hoses connect to the cylinders and that #5 Safety & Bypass valve.
IMG_20200616_192525Up above on top of that shelf Cihan has just about finished installing the hydraulic hoses for the two Accu-Steer HPU400 24Volt steering pumps. 

#11 AutoFill Valve on the far wall with the Blue Hydraulic Oil Tank on the Right.
IMG_20200617_102957Four of the 500Bar/ 7250Psi ball valves mounted on the bracket Cihan has installed on the Aft Transom wall.  These will be normally open like this but allow us to switch either cylinder out of the system if there was a leak and still maintain full steering capability.
IMG_20200618_182518One of the big jobs Cihan took on this week was routing these three hydraulic hoses from the very Aft end of the Workshop here all the way up to the manual hydraulic steering pump in the Main Helm station.

He started by exiting the center Steering Pump area to take the hoses over to the Port/Left hull under the HazMat locker you see above.
IMG_20200618_182643Then they come up along the side of the HazMat locker on the far Left and start making their way along the upper Ceiling box……..
IMG_20200618_182650………. along the lower cable tray on the Port side of the Workshop towards the WT Door out of the Workshop into the Corridor beside the Guest Cabin.

BTW, that cable tray is for the N2K and Ethernet data cables so having these share a tray with the hydraulic hoses is no problem.

IMG_20200617_095227Through the penetration in the Frame into the area behind my Office Desk wall.
IMG_20200618_100426Down the side decks behind the Fridge & Freezer cabinets in the SuperSalon.
IMG_20200618_181957And finally ending up here in the Main Helm.

And why are there hydraulic steering hoses going up here you ask?
IMG_20200618_100050  This should give you a clue to the answer.
IMG_20200618_182033As will this aluminium bracket that Uğur & Nihat have fabricated and are starting to install inside the Main Helm.
IMG_20200619_142830Exactly!  This is the Kobelt Manual hydraulic steering pump that is one of many levels of backup we have for our steering system.
IMG_20200619_184026In the unlikely event that both Kobelt steering cylinders and both Accu-Steer pumps should all fail then we can insert a steering wheel onto the SS shaft of this pump at the Main Helm and steer the boat the good old fashioned way.

Another one of these systems that we hope to never need to use but we SWAN Sleep Well At Night knowing it is there just in case.


Our ever busy Sparkie aka Electrician aka Hilmi, had another productive week so let’s see if we can find him.

IMG_20200618_100118First sign of Hilmi’s work we find over on the forward Stbd side of the SuperSalon in this Junction box that he has reopened to install four of the 11 LED Dimmer Controls.
IMG_20200618_100350three dimmer controllers mounted on the top and one on the lower Left corner.  All interior lights are LED and are on dimmable for use while on night watches, including the interior LED lights in the ceilings and the indirect lighting in the toe kicks and BHL handrails that run throughout the boat.
IMG_20200616_172209Hilmi & Yusuf found some of this new style of LED strip lights so we tested them out and REALLY like them! 
IMG_20200620_161245Difficult to capture but what is new and different is the continuous round strip of translucent silicone that runs along the thin edge.  If you look close or click to enlarge you can see the two round translucent silicone edges facing each other here.
IMG_20200616_172214This was as dark as I could make the Master Cabin but you can see what we like so much about this new style where the light is a perfectly even strip of soft diffused light along the entire length.  No spot dots of lights as in other LED strip lights so they provide a very even and very soft light.
IMG_20200620_160924Being all silicone construction, these strips are eXtremely flexible as you can see here.  This also makes mounting them very easy as we can simply press fit these pliable strips into the grooves that have been cut into the upper edge of all the Rosewood hand rails and toe kicks around all the cabinetry.  Similar grooves run under the edge of the nosing on all the stair treads which bath all the stairs in very soft safe light at night.
IMG_20200620_161416Very easy to cut these to any length you want with a utility knife and then solder the +/- 24V wires to the two little copper dots you can see on the inside of the bottom Right end here.
IMG_20200616_172232Terrible colour with all our work lights on but hopefully you get the idea of how diffuse the light is inside the BHL Blue Horizon Line Handholds on the Left here where we have temporarily pressed a short LED strip in the upper groove.
IMG_20200617_125217Hilmi was also busy down in the Basement this week filling up this Aft Battery Bank compartment with the last six FireFly L15+ Carbon Foam batteries.

The Grey PVC pipe is the extraction vent for all these battery compartments which are integral to the bottom of the hull.
IMG_20200615_124557This thick walled composite catchment tray goes in first and fits between the L-bar frames welded to the compartment floors which sit atop the upper edge of the central Keel Bar.
IMG_20200615_165039Then the six batteries can be easily lowered into the catchment tray.  Each L15+ FireFly Carbon Foam battery “only” weighs 43kg/94lbs which is relatively light compared to many of these large Traction style batteries so a single person can move them around quite easily.
IMG_20200616_124529In the Main DC Distribution Box in the background above, Hilmi has started to install the three shunts for the Victron BMV712 Smart Battery Monitors and this is the design I’ve given him to install these shunts onto the solid copper Negative Bus Bars.

Shunts A & B monitor each of the two 900Ah @ 24V battery banks and then Shunt C monitors their combined 1800Ah capacity.

IMG_20200616_095104On the opposite side of the Main DC Box is this AC Shore Power & Transfer Box which Hilmi  has now fully wired with the switches for the two shore power inlets, fore & aft and the 120V inverter selector switches.

Having all four voltages; 12 & 24V DC and 120 & 220V AC onboard provides us with complete flexibility but does require careful installation and management to do well.


IMG_20200617_125430Having lost Omer who was our lead cabinetmaker for the Guest Cabin, Office, Head/Shower, Corridor and Ships/Wayne’s Office there has not been too much progress there of late but fortunately he had completed almost all of the work in there before he left to work for another shipbuilder. 

But Omur and Selim did manage to finish the marine plywood walls, floor and ceiling in this Guest Shower so it is now all ready for the Composite/GRP Team to come in and cover all this with a seamless epoxy and fiberglass surfaces.
IMG_20200617_125439Red/Blue Hot/Cold PEX lines ready for the installation of the Shower Towers and the floor is framed to provide access to the tank access port on the Left and the Shower drain on the Right.

A removable solid teak floor will set atop this with water draining off all sides onto the sloped composite floor and out to the Grey Water tank or Sea Chest.


IMG_20200615_165304Up front in the Master Cabin you can see how the Heads and Showers are finished.  Shower in the foreground and Head/Toilet in the background with all their walls, floor and ceiling already glassed in. 

Wood template is being prepped here to go to the glass shop where they will cut a piece of 15mm/ 5/8” thick clear glass that will form a separation between the Shower and the Head areas.
IMG_20200619_100035The Rosewood Hatch Liner has now been installed inside the inner AL frame of this big 700mm / 28” overhead hatch that brings in LOTS of light and fresh air. 

As you can see in the photo above, the glass partition helps to bring in both light and fresh air to both the Shower and the Head areas.
IMG_20200619_095951Frames are all clamped in place.
IMG_20200619_100330And look like this from up on the Foredeck. 

The groove around the outer perimeter provide the space for the inner leg of the rubber hatch seal system which wraps around the 8mm thick AL edge of the inner hatch frame.
IMG_20200619_100335Looking down the side of one of these hatches you can see how the inner and outer AL frames create a gutter to trap water and drain it out through one of the two holes in their bottom which you can see in the middle here.

SuperSalon CEILINGS:

IMG_20200617_095257Most of Omur and Selim’s time this week was spent working on the ceilings in the SuperSalon.
IMG_20200617_125040Each of these 10mm/ 3/8” thick plywood panels will be covered in White leather and use FastMount fasteners to snap in place to the Black ceiling grid.

IMG_20200616_192940The two sets of 5 circular holes seen here are where the air diffusers will be installed that bring fresh air into the Main Helm up front and the Lounge, Dinette and Galley aft.
IMG_20200617_140652For those not familiar with it, the FastMounts are a fabulous product out of NZ that create super easy snap in/snap out panels which we are using for all the ceiling and wall panels throughout the boat.

Two part system with these Male halves mounted to the inner surface of each ceiling panel.

IMG_20200617_140731IMG_20200617_140732With a matching Female socket threaded into the Black ceiling grid above.

Just as quick and easy to install as they are to snap in/out and give complete access to what is behind them.

IMG_20200617_183629Almost all the ceiling panels in place, just a few at the very Aft end which they finished installing on Friday.

Smaller Soffit panels down each side are also removable and finished in White leather.
IMG_20200617_183712They have trimmed the corners around the Plinth where you walk through the Entry Door from the Aft Deck with these generous 50mm / 2” radiused corner moldings.
IMG_20200618_113644Which made a quick trip to and from Naval’s Upholstery Shop to get their matching White Leather applied.
IMG_20200619_095833Doesn’t take too much imagination now to see how the ceilings will look once all these panels are also covered in their White leather with the contrasting Black epoxy in the adjoining spaces between each panel.

Have I mentioned that we are LOVING the way the whole look and feel of the interior is now coming into view?

IMG_20200618_181719These three ceiling panels over the Main Helm also just returned from the Upholstery Shop covered with their Black Leather and quickly snapped in place. 
The three panels behind these will also be covered in Black Leather to further reduce light reflections at the Main Helm on night passages.

MVIMG_20200616_193002Selim finished off the upper stair before week’s end so they are now all framed and insulated and ready for their Rosewood Risers and trim.
IMG_20200615_103923And to finish things off in the SuperSalon for this week, Omur has started to fit the sloped top of the angled Stbd/Right side of the Main Helm.
IMG_20200615_103937This will be hinged at the top to provide easy access to the electronics and storage areas inside.

Mr. Gee Gets His Head(s) Screwed on Tight!

Not to be left out I was able to give Mr. Gee our Gardner 6LXB main/single engine a bit more TLC this past week.

IMG_20200615_120914If you were with us last week you saw me install the two fully rebuilt cast iron cylinder heads onto the Cylinder Block and this week I was able to get put in all the nuts and fully torque both of Mr. Gee’s heads down nice and tight.
IMG_20200615_121241Most of the nuts on Gardner engines do not use any washers but I do use the appropriate strength thread locker on all of them for that wee bit more assurance that they won’t ever come lose yet can be easily removed if needed.
IMG_20200615_123302Having two individual heads side by side, you need to first clamp a straight edge along the edge of both to ensure that the exhaust/intake manifold sealing surfaces are fully aligned before tightening the Heads to the Cylinder Block.
IMG_20200615_175003With both heads fully torqued down it was time to install the new valve train.  Push rods go in first and connect the valve lifters sitting atop their cam lobes on the camshaft down below.
IMG_20200615_175016Next up are the Valve Rocker Arms which transfer the Up/Down movement from the Pushrods over to the Intake and Exhaust Valves on the opposite side.

The Gardner 6LXB has three shafts that run down the center of each head with two Rocker Arms hinged on each.  You can see one of these shafts lying at an angle at the far end here.  The shaft in the center is on its way to slide through the two Rocker Arms in the foreground.
IMG_20200615_175423Here is how that looks from the other end with that first shaft now in place supporting the two Rocker Arms.
IMG_20200615_175411Looks like this closer up. 

Spring in between to keep each Rocker Arm up against their outer thrust surfaces.
IMG_20200615_183928All these little soldiers all in place and ready for the initial valve clearance adjustment. 

Easy to see how simple this age old valve arrangement works with the Up/Down movement of the Push Rods down the Right side being transferred by the Rocker Arm in the center to Open/Close each Valve on the Left.
IMG_20200615_184319One additional and rare feature for the valves are these two shiny Aluminium levers which when rotated push up on the underside of each Intake Valve to hold them open and not allow any compression in the cylinders and are therefore called Compression Release Levers.

Why would you want to do that you might ask?  Several reasons but the two most important to me are;

1.  With no 15:1 compression to resist, this enables me to easily turn the engine over by hand for doing adjustments or to build up a bit of oil pressure before starting to name but two examples.

2.  But THE best and most important reason is that this also makes it possible for me to HAND START this engine! 

Hand crank starting used to be a very common feature on early cars, trucks and tractors of which I have restored quite a few so I know first hand.  And some of you may recall seeing scenes in movies or documentaries of people starting their Model T or other cars in the early 1900’s by turning a crank they inserted up front.  In smaller gasoline engines the compression was small enough that you didn’t need a compression relief system but in larger engines and especially diesel engines which have much higher compression ratios the resistance from the internal compression was too high to turn by hand so they had this kind of compression release system which enables a well fed highly intentioned person to get the engine spinning over fast enough to then flip the compression back on and Umph Umph Umph each cylinder fired and you were off to the races.

Seriously folks, I am NOT joking with you or pulling your leg about this. 

OLD Gardner Hand Start Illustration Plate 10Need more proof, well check out this illustration of what will soon be Mr. Gee’s Hand Starting system!  indeed this is a VERY serious safety feature for Christine and I in our single engine boat. 

In fact when I first told Christine about this ability to hand start a Gardner before we found and bought Mr. Gee, her words were “You had me at Hand Crank Start.  I want a Gardner on MY boat!”  and the rest as you are seeing is history.
Old Hand Crank model 1More proof?  OK, here is a photo of the Gardner Hand Start system “in the wild” courtesy Michael at Gardner Marine Diesel.

While we of course carry a full compliment of spare parts such as bearings and brushes for our massive 24V Gardner starter there is still always the outside chance of a catastrophic failure of any starter which I could not repair at sea or some complete loss of DC power which would render us quite literally “dead in the water”.  So having this ability to hand start Mr. Gee if we needed to is an eXtremely big deal and could be a life saving feature so we count this as one of our top safety items onboard XPM78-01 Möbius.

I’ll leave it at that for now and go into more details once I start restoring and installing the Gardner hand start system on Mr. Gee so stay tuned for that riveting entertainment to come.

And with that I’ll sign off for this week and go enjoy the rest of this wonderful summer evening with my Beautiful Bride aka Captain Christine.  A very big and sincere thanks to YOU for joining us and congratulations if you made it this far!  I know I am seriously “brevity challenged” but you know where the Page Down key is on your keyboard or how to swipe down to get here quickly if need be.

See you again same time, same place next week.



NOW THIS is EXHAUSTING! XPM78-01 Möbius Progress Update June 08-12, 2020

Another full 5 day work week, well six really as some work is being done today (Saturday) as well so lots accomplished and lots to show you in this week’s Möbius Progress Update so let’s just jump right into the Show & Tell.


IMG_20200612_094649If I give you the clue that this week’s title is in reference to one of the last big ticket bits of kit that we need to complete the building of XPM78-01 Möbius, can you guess what 66kg/146lb worth of mechanical goodness is inside this latest crate to arrive at Naval Yachts this week?
IMG_20200612_100607Does it help you guess if I remove all the outer shrink wrap?
IMG_20200612_101335OK, I’ll give it away with this shot of pure boat jewelry.

Yup, our exhaust system finally arrived from Halyard in the UK.  I only say finally because I first met with Oliver from Halyard’s HQ in the UK back in October of last year so it has taken us eight months of working very closely together to come up with the Goldilocks Just Right exhaust system for XPM78-01 Möbius.  Oliver and his whole team of engineers and designers have been excellent for Yigit and I to work hand in hand with making all the right compromises, decisions and trade-offs which are always a part of designing any system due to the large number of variables and conditions we strive to meet. 
Halyard exhaust system isometric from HalyardHere is a quick sketch from Halyard showing all the components they built for us in Green which arrived this week in the crate you see above.

The flexible 76mm/3” ID exhaust connection to Mr. Gee is shown in Black in the bottom Right and then following from there here are the components:

*  SS 76mm/3” ID Vertical “dry” riser

*  SS 76mm/3” ID Horizontal “dry” riser

*  SS 127mm/5” Spray Head or Wet Elbow connected with silicone hoses on both ends

*  Halyard GRP Silencer/Separator

Halyard exhaust system renderingOne of Yiğit’s renderings provides another perspective where you can see the 2D outline of Mr. Gee to see where the Halyard exhaust system connects to his Red exhaust manifold on the Aft end of the engine.
Halyard Exhaust 3This is an example of one of many models as we tried out different options and layouts, this one being the vertical position of the Halyard Combi Silencer/Separator that mounts in the Forward Port/Left corner of the Engine Room up against the vertical intake air duct shown in Purple here.
Change to 45 degree outletAnother part of the evolution of the design we worked out with Oliver and his team was to change the exhaust gas outlet on the Combi to be at a downward 45 degree angle for a better routing of this hose down and across the WT Bulkhead to where it exits the Engine Room Enclosure.
combi_silencer_003This early render of the Engine Room Enclosure and the Stbd side of the Workshop shows how the rubber exhaust hose coming out of the Combi goes down and out the Stbd ER wall and then passes under the Orange Day Tank on its way out the angled aluminium exhaust pipe through the hull about 300mm/12” above the Waterline.  Gardner engine is shown here as the Blue box just to give its basic volume, ER Intake Air Duct in Purple on the Front Port corner of the ER and the Cyan coloured cylinders on the Stbd side of Mr. Gee are the two Seawater Strainers from the Intake Sea Chest in the Stbd corner of the ER.
Halyard Sprayhead wet exhaust colour illustrationThis is arguably the most important component in any and certainly our wet exhaust system, the SS Spray Head or “mixing elbow” which is what I had in my hand in the give away clue up above and to my eyes Halyard’s execution of this is pure boat “porn” or jewelry as we sometimes refer to such works of art and engineering.  Looking at Halyard’s cutaway illustration here shows how the still dry exhaust gas only enters the elbow on the far Left and then has sea water pumped through the smaller ID hose on the top where it is then injected into the exhaust gasses flowing out the large rubber exhaust hose on the Right.  This water serves two critical functions as it both quiets the exhaust gas sounds and cools the gasses down so low that they can easily now be routed through certified rubber exhaust hoses which are much easier to work with and place compared to hot SS exhaust pipes.

The small angled fitting on the Right is an exhaust gas temperature monitor that notifies us and set off an alarm if the temperature ever rises which would mostly be due to a reduction or stoppage of the sea water coming in.  If the wet exhaust sea water should ever stop, usually due to the sea water impeller pump or drive belt failing, the temperatures inside the “wet” side of the exhaust system would immediately soar and start causing all sorts of severe damage to the rubber hoses and the Combi itself.  And yes, this is another place where I can say “Ask me how I know?!”.  So in addition to this wet exhaust gas temperature sender which will put that data onto the N2K and Maretron monitoring system, I also always install at least one temperature alarm sensor on the outer surface of the rubber exhaust hose just aft of this internal sensor for both redundancy and possibly an earlier warning of an increase in the wet exhaust gas temperatures.

IMG_20200612_101340Here is the real deal and if I hold it at this angle looking into the end where the wet exhaust gas plus water exits you can see now the water is very evenly injected into the exhaust gasses through all those semi-circular holes around the circumference.  The way this works is that there are actually two SS pipes here, the large 127mm/5” outer pipe I have in my hand and then the smaller inside pipe we are peering into here.  This creates a space or jacket between the inner and outer walls of these two pipes.  The sea water, enters through that small SS pipe in the upper Left side, fills and flows through this space or jacket between the two pipes and is then forced through all those semi-circular holes much like the spray head on your garden hose or shower. 

Cheaper systems just have the sea water enter directly from the sea water hose but this does a very poor job of mixing the water with the gasses so while not easy or cheap to execute this double walled injection system that Halyard has made works eXtremely well and reduces both noise and temperatures of our wet exhaust system very effectively and efficiently.

For those of you who might want to do a deeper dive into marine diesel engine exhaust systems THIS TONY’s TIPS article from Seaboard Marine will give you a very good overview of the various types and how they work.

halyard Combi Silencer-Separator catalog 2D labelledThis 2D drawing from Halyard’s catalogue shows the Side In/Top Out style we are using, with the noted change that our outlet is angled down 45 degrees.

IMG_20200612_101502The Combi Silencer/Separator was shipped upside down as you see here so that is the nice thick GRP base plate that I’ve got my hand on is up on top here but will give you an idea of its size and shape which you’ve been seeing in the renderings above as well.

For those not familiar with these Combination Silencer/Separators they are very simple in operation and eXtremely efficient.  The now wet exhaust gasses + seawater coming out of the Spray Head enter the Combi Silencer/Separator through the 127mm/5” ID angled side inlet pipe “A” in the drawing below, where it expands inside the large cylindrical GRP chamber.  From there, the seawater is separated out as it flows out the bottom pipe at “C” which in our case connects to a rubber hose going directly into the Exit Sea Chest that sits right below the Combi while the now cooled and silenced exhaust gasses exit through the upper Outlet “B” and are then routed over to the exhaust pipe exit from the hull via rubber exhaust hose.

I went with this Combined style of wet exhaust for many reasons, the two biggest by far being that this style requires no “Lift” of the sea water which the more common Lift Muffler design has which creates much lower power robbing back pressure for Mr. Gee and in a Good/Better/Best rating, these Combi styles are the Best as they have the highest degree of quieting of the various different wet exhaust styles.

You’ll be seeing lots more of all this as the installation starts in the next week or so.


Uğur and Nihat are still working on other boats so no progress this week on their aluminium related work but the ever productive Cihan had another very successful week as he continued with his installation of the Kobelt Steering system so let’s go catch on with that next.

Mobius Steering SystemThis simplified schematic of our Kobelt Steering system which Christine created shows how the major components are connected together electrically
Kobelt steering hydraulic schematic 0093-Pi_RevAand now Cihan is working on all their hydraulic connections as shown in this schematic we developed with Kobelt.  You can see the two 7080 cylinders connected to the Tiller Arm at the top Left and the two HPU400 hydraulic pumps below them.

IMG_20200605_100108If you have not yet seen last week’s update you can go back to that to see the initial work that led to this point with the physical mounting of the two big Kobelt 7080 hydraulic cylinders and they are now both connected to this massive Tiller Arm which we was CNC machined out of a single block of AL which is also now fully installed onto the Rudder Shaft you can see poking out the top here.  Now it was time for our Master Plumber Cihan to start connecting all the hydraulics together.
IMG_20200609_154459These eXtremely robust base mounts for the outer articulated ends of each cylinder have now been fully welded in place and the cylinders are loosely connected for now while Cihan works his hydraulic magic to connect everything together starting with the hoses at each end of each 7080 cylinder.
IMG_20200609_154357Up above on top of the Aft Workbench which runs the full width of the Aft end of the Workshop along the entire Transom Wall on the far Left, the two Accu-Steer HPU400 24V continuous running pumps are mounted and ready for their hydraulic and electrical connections.
IMG_20200611_094403Cihan has mounted the horizontal AL bracket to the Aft Transom Wall and has bolted four of the high pressure ball valves to this so they are now all ready ……
IMG_20200611_141734….. for their hoses to be connected.

IMG_20200611_095015All the hydraulic hoses are 1SN DN13 rated for 160Bar/2320PSI
IMG_20200611_094900With the neccessary ends swaged on in house.

IMG_20200609_154420In the center of the schematic above is this Safety & By-pass valve which Cihan has bolted to a this small bracket to put it close to the Tiller Arm on the Left and make for the shortest overall hydraulic hose lengths.
IMG_20200611_170036Some more simple L-bar brackets welded to the underside of the Aft Workbench to hold and organise all the various hydraulic hoses he has made up.
IMG_20200612_095044As per the hydraulic schematic above the hydraulics for each cylinder are interconnected to provide the maximum flexibility of our steering where just one pump and on cylinder exceeds the steering requirements in any conditions and can do so using either the high speed or low speed option.  However to add more power and flexibility we also have the ability bring both pumps and both cylinders online at the same time. 
This gives us the option to double the speed and halve the time it takes to move the rudder from lock to lock which is a total of 90 degrees as our Rudder can turn up to 45 degrees to either side.

Cihan was clever enough to fabricate two 4-way connectors to help organise all these hose connections and you can see one of these 4-way junctions just to the Left of his elbow.  If you look closely or click to enlarge, you can see that the second 4-way connectors sets atop the first one.

IMG_20200612_095029Here he is a bit further into the installation and viewed from the side so you can see how he has stacked the two 4-way connectors atop each other.  The Yellow plastic blocks are clamps which safely hold all the hoses in position with no chafing or movement once they are all clamped down.
IMG_20200611_182111Two pairs of those hoses need to connect to the two Accu-Steer HPU400 AutoPilot pumps and you can see these coming up from below to connect to their respective high pressure 150 Bar ball valves that we saw Cihan had mounted up above.

And that pretty much finishes off the initial installation of the hydraulic hoses for the Accu-Steer pumps and Kobelt cylinders.  Next up are the long hoses that need to go all the way up to the Main Helm where the manual hydraulic steering pump where our Emergency Steering Wheel can be connected if ever needed.  More on that next week.


MVIMG_20200612_164246Hydraulics are not the only type of connections being made aboard the Good Ship Möbius this past week as Hilmi, seen in the background here, continues his relentless work installing the nautical miles of electrical wire, cables and now network cables.  As you can see by the large coils in front of the Workshop WT door he is now pulling some of the very long runs of cable and so “Mr. Swiss Army Knife” Mummy has been lending his very skilled helping hand.

For the most part Black cables are 120 and 220V AC and Grey are 12 and 24V DC.
IMG_20200608_100004Last weekend Hilmi finished wiring the Forward DC Distribution Box in the Forepeak which feeds all the high amp 24 Volt consumers up there such as the Maxwell VWC4000 Windlass, Lewmar 55EST Evo kedging winch, Vetus 2024DE Bow Thruster.  Plexiglass safety shield now installed and job well done Hilmi!
IMG_20200608_095651Down in the Basement where the Main DC Distribution Box is located Hilmi has also been busy connecting the large 24V DC cables to the Positive and Negative solid Copper Bus Bars and now starting to add things like the shunts for the Victron BMV712 Smart Battery monitor.

Two of the three shunts you can see bolted to the Negative Bus Bar on the Right with their two large 120mm2/AWG 5/0000 Black cables attached that go down to each of the four 24V @ 450Ah Battery Banks located directly below in their aluminium compartments which are integral to the hull.

Victron BMV712S Shunts   MPPT connections illustration by CKCaptain Christine whipped up this spiffy illustrated schematic that shows how these three shunts are all interconnected along with the data connections for monitoring all five of the Victron MultiPlus Inverter/Chargers, three 220V and two 120V.
IMG_20200608_095706Close up shot of one of those BMV712 Smart Shunts so you can see the additional connections that come off of each shunt and go up to their BMV712 gauge heads up in the Main Helm.  There are three of these BMV712 Smart Battery Monitors and their respective shunts; two for monitoring the two 24V @ 900Ah Battery Groups A and B and then a third to monitor the whole House Battery Bank which is 24V @ 1800Ah. 
Such detailed monitoring is critical to our existence because Möbius is a completely DC or “Battery Based” Boat whereby all of our four electrical voltages, 12 & 24V DC and 120 & 220V AC, originates from our 24 Volt House Battery Bank.  So we make battery and electrical system monitoring a top priority and it all starts by our monitoring the 24 the FireFly L15+ Carbon Foam batteries which makeup our huge House Battery Bank.

IMG_20200608_095739The latest addition to our Victron Blue Wall down in the Basement is one of two 70Amp Victron Orion 24V to 12V DC to DC converters which are the source for all our 12 Volt consumers that include some electronics and some pumps that are only available in 12 volt models.  Our primary voltages are 24V DC and 220V AC but we have both 12 volt and 120 volt outlets positioned where needed throughout the boat so that any voltage you want is readily available.  We really like the options and flexibility this affords us so that we don’t need to replace any of our existing equipment and purchase new items no matter what voltage they require.  Also nice for all our family and friends when they are visiting us so that they too can plug in any of the electrical bits and bobs they want to use.
IMG_20200608_095745Stepping back a bit to show you this Orion’s new home.
IMG_20200609_122517This spool of cable showed up onboard Möbius this past week and it isn’t like any of the other cables onboard so far so any guesses as to what this is for?
IMG_20200609_122522Yup, this is our CAT7 cable that we will be using for all our Ethernet based data. 
MOBIUS Ethernet Network Diagram-2-iMacAnd as this schematic which Captain Christine put together will help you see just some of our Ethernet cables, we do have a LOT of data to move throughout the boat.  So yes, you are reading that label correctly, this is 305m/1000ft of CAT7 cable! 

Most of you are probably familiar with and using CAT5 or CAT6 Ethernet cable which still works just fine but we try where we can to “future proof” Möbius and this is one example. 

CAT6 7 8 comparison tableWhat’s the difference you ask? 
This chart shows some of the difference and yes, there is now CAT8 cable which we might have used but could not get delivered to us here in time.  The differences that matter to us are that we can have little to no loss with long runs and most importantly CAT7 has significantly more and better shielding so we get less “noise” and interference with our data transmissions if they happen to be near such interference from other devices.  We have routed all our data cables in their own cable trays and kept these well distanced from the other cable trays carrying AC and DC wires but the added shielding of CAT7 should eliminate any last bit of noise that might try to sneak aboard.

CAT6 CAT6a CAT7 cable photosCAT7 is quite different internally with the added shielding and you need to use special connectors that have the connections for the shielding in place so you can’t use standard RJ45 connectors.  But Christine was able to source all the CAT7 male and female end connectors we needed with lots of spares along with the new crimping tool so we can make up our own CAT7 cables as needed for future expansion. 
Best thing is that the CAT7 connectors still have the exact same form factor as RJ45 so they snap into our RJ45 based wall plates to replace the old ones.

IMG_20200610_100141Let the CAT7 cable running begin! 

Here is some coming out of the ceiling above the Corridor outside the Guest Cabin.
IMG_20200612_164235More overtop the Ships/Wayne’s Office
IMG_20200610_125702More in these bookshelves……..
IMG_20200610_125716More in this little “Internet Alcove” by the stairs……
IMG_20200611_142245More in the Workshop ………………………

Well, you get the idea, more CAT7 EVERYWHERE!

Stay tuned for much more in next week’s update.  Let’s move on to something else quite electrifying to me …… Ro$ewood cabinetry.


MVIMG_20200610_173205Next door in the Cabinetry Shop Omur is now busy making up more vents for the Extraction Fans in the SuperSalon.
IMG_20200610_173431Which soon emerge looking like this and ready for cleanup and machining the outer frames to size.

IMG_20200610_100346Then they head up to the Finishing Shop to receive their 5 coats of PU Poly Urethane varnish which transforms them into beauties like these two down in the Master Cabin.
IMG_20200610_100330These are two of the many more ventilation grates that Omur has been busy making for the various air Intake/Return and Output/Supply vents for Hot & Cold AirCon, Air Handlers, Extraction Fans and so on.
IMG_20200610_100317These two are destined for the air supply to the Air Handler located inside,,,,,,,,
IMG_20200610_100401……. the cabinetry on the Port side of the Master Cabin bed.  One Rosewood grill on each of the two stair risers, the upper one of which we see here.


IMG_20200612_164442Upstairs in the SuperSalon continues to live up to its name more and more with the passing of each week and here we find Selim starting to fit the Rosewood risers for the stairs leading up to the WT Entry/Exit door from SuperSalon to the Aft Dec.
IMG_20200611_182340Earlier in the week they had installed the foundations for the stair treads by leveling and gluing them to the AL stairs.
IMG_20200612_121728Selim added the spacers for the stair risers we saw him installing above.
IMG_20200611_130554Climbing up those stairs and turning around to look back inside the SuperSalon we spot another new addition this week.  Can you see it?
IMG_20200611_130544Good eyes!  This little box in the top front corner of the Plinth overtop the stairs will soon house a bunch of the electronics that feed the Upper Helm Station in the SkyBridge which is on the Stbd/Right side of this Plinth and photo.  All the surfaces in here will have snap in place FastMounted leather covered panels including one that will go over that rectangular opening you see here to make it easy to access items such as some network switches, N2K multi-port blocks, second boat computer and all the cables and wires that feed through ………………..
IMG_20200609_122505………. this penetration at the very top Right corner heading into the Upper FlyBridge Helm Station on the Right.
IMG_20200611_095133Back down inside the SuperSalon Selim has been busy all week doing the final leveling of the rigid foam board below the floors so that it is all flush and level for the 12mm / 1/2” marine plywood floors.  Once these are all leveled they will then route all the U-shaped grooves that will hold the 15mm / 5/8” PEX tubing for the In-Floor Heating system.

And if you peek through that big hatch in the floor you can see the Main DC Distribution Box that Hilmi has been working on down in the Basement.
IMG_20200610_173149Back to the Cabinetry Shop to catch up with the Hatch Liners Omur and Selim have been working on for the past few weeks. 
IMG_20200610_173145These two are soon headed for the Finishing Shop before going to their final destination inside the AL Hatch frames in the Master Cabin.
MVIMG_20200609_122444Progress continues in the Galley as well with the gluing up of the infamous BHL or Blue Horizon Line Handhold that wraps around the marble countertops which are out at the waterjet CNC cuter right now.
IMG_20200608_161535And they have now finished putting in all the Black Ceiling Grid components so it is now all ready for them to install the FastMount sockets that the ceiling panels snap into so please join us again next week to see that.

Mr. GEE!

IMG_20200611_170819Easy for most of you to guess what we’ve left for the last section of this week’s Möbius Progress Update but can you guess what these studs are all getting cleaned up and ready for?
IMG_20200611_183815eXactly!  Mr. Gee is ready to have his head(s) bolted on once I got ALL these different studs all fully cleaned up, threads redone and threaded into the cast iron Cylinder Block.
IMG_20200612_185102Studs all torqued down into the Cylinder Block, Head gaskets in place and rubber O-ring water jacket seals pressed in place.
IMG_20200612_185108Cylinder Heads all rebuilt with new valves, valve guides and reground Head to Block surface so time for the Front Head to “Fly” into place.
IMG_20200612_185554All those studs make it easy to line up the head just right and start lowering it in place.
IMG_20200612_190354Front Head in place so time for the Aft Head to join it.
IMG_20200612_190621Et Voila!  Mr. Gee grows closer and closer to a working engine and ready for his next 50+ years of uninterrupted service as XMP-78 Möbius’ source of propulsion.
IMG_20200612_190716Front head already has its compression release shaft in place with its aluminium handle poking out between the two heads so time to install the one in the Aft Head.  These levers allow you to hold the exhaust valves open so there is no compression in those three cylinders and makes it easy to turn the engine over and even, are you ready for it ………………. HAND START the engine!  Lots more on that whole story and installation in the coming weeks so I’ll leave it at that for now.
IMG_20200613_141612Just for show I put the sand blasted AL Valve Covers in place just in time for inspection by the Captain.
IMG_20200613_141603Several years ago when I was first Waynesplaining to Christine that we would be able to hand start Mr. Gee, she smiled even more than she is here, held her hand up to quiet me and said “You had me at Hand Cranked, I want a Gardner in my boat.” She is getting closer and closer to getting that wish.

Yiğit’s Presence Lingers On

IMG_20200607_215007Last week we had to say goodbye to our Project Manager Yigit as he headed off for his compulsory stint in the Turkish Navy and so before he left Antalya we had him over for dinner on Sunday for one more chance to spend some time with this eXtraordinarily talented young man who is also our dear friend. 
IMG_20200607_215105Ruby and Barney love “Uncle Yigit” even more than we do it seems as he has been our dog sitter for many weeks over the past 2+ years so it was a chance for all of us to squeeze in a bit more time together.
Being the sweet and thoughtful man he is, two days later a package showed up at our door with a surprise gift from Yigit inside that is just so Yigit and so perfect.

His and Hers Captains Caps!  So we just had to head into Naval Yachts on Saturday to take some photos to send to him, so Yigit, thanks and these are for you…………

IMG_20200613_133748In front of the Main Helm
IMG_20200613_134245  Up on the Foredeck
IMG_20200613_134028And testing out the “Dolphin Seats” at the Bow.

Thank you SO much Yigit!  Your presence and talents are missed more and more every day by everyone on Team Möbius and most of all by Wayne & Christine.

Well, that’s a wrap for the week that was June 8 to 12, 2020 so I’ll just add my thanks to all of you for joining us here for this week’s update and for joining us on this grand adventure.  Hope you’ll be back again next week and PLEASE let me know what’s working and what’s NOT with these posts as well as any and all questions and suggestions you have along the way.
