New Arrivals = Mount Up! XPM78-01 Möbius Progress Update 02-06, 2020

This will be a much shorter blog post than usual (lucky you!) as it was just a one day work week at Naval Yachts this week with them being closed from Nov. 3-10.  However, as usual there was still some very exciting new developments and new arrivals this past week that both Christine and I are anxious to share with you.  The theme this week seemed to be about “mounting” new items that have just been delivered such as mounts for pumps & alternators, mounting computers and mounting/installing glass walls and doors in the showers.  Without further drivel from me, please grab a comfy chair and a good beverage and come along for this week’s Show & Tell here in Möbius.World.

SHOWERS:  Works of Art & Engineering

I’ve been showing you for many months the progress in building the Heads and Showers in the Guest and Master Cabins and our extensive use of glass in both.  This week all these glass panels were delivered to Naval Yachts so we can finally show you what the real thing looks like although you will have to wait for another week or two to see them fully installed aboard.
03For those that are new here or don’t remember, here is a quick rendering of the Master Cabin from the perspective standing in the Entryway door looking forward towards the Bow.  Note the two glass plate walls that form the corner of the Shower in the background of this render.
01Switching locations, here is what it looks like when standing front and center in the Master Cabin looking Aft with the etched glass Shower wall corner in the foreground on the Right.
Sherry working on shower glass imagesWe are SO grateful to be surrounded by so many talented family and friends who very generously and excitedly want to apply their many talents to features inside of Möbius.  Here is one of the best examples; our dear friend Sherry Cooper in her AbFab apartment in downtown Vancouver B.C. working with us on the graphic designs to be etched into those glass corner wall panels.
shine_on_c._sherry_cooperI have known Sherry and her husband Rick since we were teaching High School together on the Canadian jet fighter base in Baden Baden Germany in 1980-84 and to say that Sherry is talented is about as big of an understatement as I know how to make.

To find out more about Sherry and see what I meant check out her other works HERE and HERE as well as her Instagram page HERE.
Christine and I worked with Sherry to describe as best we could what we wanted to achiever with these etched patterns which was things such as a marine/nautical theme, a taste of First Nation people’s art from the British Columbia area we know and love and to have all this captured in a somewhat abstract and ethereal way.

This is what Sherry came up with and we think the nailed it!  A perfect example of our favorite Goldilocks; just right, just for us type of result.
Etched Glass paterns from Sherry Cooper and Hakan vector fileThe sketches above are relatively small hand sketches and we needed to transmogrify these into much larger sizes and be in a CAD/CNC format for the etching work to be done.  Hakan, one of our former Team Möbius members took on this task and created these two Vector based files in AutoCAD which we then sent to the glass etching company.
Shower Glass Wall etchingThe etching company used these vector files to CNC cut these shapes into white peel & stick vinyl which they then attached to the two glass panels and sent us this photo on WhatsApp to make sure this was what we wanted and then they went ahead and did the etching.
PXL_20201104_113555520Here are the finished panels that were just delivered with all the other glass panels stacked on top and set onto a table below Möbius for now as they await being carried onboard to be installed.
PXL_20201104_113618020To give you a bit better idea of what these etched panels actually look like, I slid the glass stacked on top off to the side a bit to shoot this for you and give you a bit better sense of the real thing.

Thank you SO much Sherry!  We LOVE what you’ve done and we can’t wait for you and Rick to come join us and take over the Master Cabin so you can shower within your own “walls of art”.
PXL_20201028_071112613Back in the Guest Cabin we are keeping it a bit simpler with “just” a plain glass door for the Guest Shower that you can see in the stack of glass above and will also soon be installed.

Boat Computer #2

PXL_20201108_070015617We need plenty of computer muscle to power all the sophisticated navigation software, equipment, monitoring and multiple monitors we have onboard the Good Ship Möbius and so Christine has been busy researching, specifying, ordering and building our two Boat Computers.  She finished our primary PC a few months ago and this week the 2nd Boat Computer arrived from the US.
PXL_20201108_070001169This is a Kingdel fanless mini PC which Christine finally tracked down on Amazon US and had shipped over to us here in Antalya.

How fast is this new little guy?  Well, Captain Christine, who is normally an Apple Gal I might add, said “It boots up faster than you can say Windows 10”

Our newest family member will live in the overhead space above the main Entryway beside the SkyBridge helm station which is what it will primarily power.

For our fellow Geeks and Geekettes out there, below is a peek inside and the basic specs:

  • CPU: Intel 10th Generation i7-10510U, 4 Cores, 8 Threads; Comet Lake; 8MB Cache, Base Frequency: 1.8GHz; Max. Turbo Frequency: 4.9GHz.
  • 16GB DDR4 2666MHz RAM,
  • 512GB M.2 2280 SSD;
  • Intel 82574L Gigabit Ethernet LAN;
  • Dual Band 2.4/5GHz Wireless Network Card.
  • Integrated Intel UHD Graphics, 4K: HD, 4096×2304@24Hz; DP, 4096×2304@60Hz;
  • Gigabit LAN Port, HD Port, DP, 4 USB 3.0.
  • Fanless, Smart Design, Full Metal Case, Silent Working, High Speed CPU & SSD, 2 Years Warranty.
  • Pre loaded with Window 10 Pro, complete with full license key for reinstalling.


  • PXL_20201108_070153148
  • This is Christine’s temporary techno test bench in our apartment where she has both Boat Computers hooked up to load up all the software and start configuring them all.

PXL_20201108_070158096Boat Computer #1 is seen here underneath the table as it has a larger “desktop” size which provides much more space for multiple fans to keep things cool, more expansion board spaces and other advantages we wanted.  It is “only’ an i7 9th generation processor but can run all six of our big monitors and will be our main “go to” computer when we are onboard.
PXL_20201108_070115140.MPI thought this shot might give you a better perspective on the size differences although the Mini PC I am holding in the foreground appears larger than it really is due to being so much closer to you in this shot.

Synology NASFor those wondering, the black box on top is our Synology NAS or Network Access Storage.  You can slide different hard drives and SSD’s into this box and right now we “only” have two 4TB hard drives in there but easily expandable and we just took note of two Western Digital drives that are 16TB each for just $200 so we will see if we need more storage and add as we do.

We use all this storage volume on our NAS to hold everything from our huge vaults of music and movies for our onboard entertainment and on them more serious side this also holds multiple sets of electronic charts for the whole world, satellite images, all our manuals for all our onboard equipment, all our software both personal productivity software such as MS Office and all our navigation software such as TimeZero, Coastal Explorer,

Why not just keep all this in the cloud?  We do this too, but this NAS gives us direct access to everything without any internet connections at all.  So this creates what you can think of as own personal “onboard cloud”.

Mounting Jabsco Sea Water Pump
Keel cooler like on LTY

For the Gardner engine cooling, I had wanted to install a keel cooler which is made by cutting lengths of aluminium pipe in half lengthwise and welding these to the outside of the hull with U-turns on the ends to create a continuous loop.  The two In/Out ends are then welded through the hull and the engine coolant (anti-freeze + water mix) is circulated through this loop and transfers its heat out into the passing sea water.  Super efficient, no extra pumps or moving parts required and I had this on our previous boat that worked great.
Heat exchanger closed cooling sytem illustrationHowever, for a variety of reasons Naval switched to a heat exchanger style which works like this.  Sea water is drawn in through the Sea Chest and strainers by an engine driven sea water pump which then circulates the cool sea water through a variety of heat exchangers for the engine coolant, engine oil, transmission/CPP oil and finally goes to the wet exhaust to cool it and then the sea water goes out through the exiting sea chest back into the ocean.  These heat exchanger style works fine and is on thousands of boats, just more complex and more moving parts as you can see.
Bowman heat exchanger external viewAfter some research we chose to go with a Bowman heat exchanger which are one of the world’s largest heat exchanger manufacturers based in the UK and they are beautifully made bits of kit to be sure.
Heat exchanger how it works internal illustrationHere is a generic illustration showing how a heat exchanger works and it could not be more basic; cold sea water enters the large cylinder (Shell Inlet) and flows around all the smaller tubes inside picking up their heat and then exits out the other end (Shell Outlet).  The liquid to be cooled enters the Tube Inlet and runs through all the small diameter rods or tubes that are surrounded y the colder sea water and then exits out the Tube Outlet having given up most of its heat.
Bowman titanium inner tube heat exchangerThat inner “Tube Stack” as it is called is made out of Titanium in ours and you can see that it is simply a bunch of small diameter tubes which are bundled together and have liquid going into one end of each tube and then out the other.
Heat exchanger internal tubes photoI didn’t want to take our Bowman’s apart but here is a similar model that will let you see how the Tube Stack fits inside the larger diameter heat exchanger body where the sea water flows.
Heat exchanger style illustrationSorry, not the greatest quality but best I could find in a pinch here late tonight but this should show you the basic layout and how the various liquids flow through a heat exchanger system.

Jabsco 6400-1051 sea water pumpAs you can see this is all simple enough but it does require the addition of a sea water pump to pull in the sea water through the Intake Sea Chest in the Engine Room and then pump it out through all the various heat exchangers and then finally provide the sea water that is injected into the wet exhaust elbow to cool the exhaust gasses.

I chose this Jabsco 1 1/4” bronze pedestal base sea water pump as I have had these in previous boats and know them and their maintenance quite well.  I like to “go with what I know” you know!
 PXL_20201102_121900903The next bit of “complexity” is that we now need to mount this Jabsco sea water pump and figure out a way to have Mr. Gee drive it.  Cihan has his hands more than full so I have taken on building this mounting system for the Jabsco pump.
PXL_20201102_121907066The Gardner 6LXB often had sea water pumps mounted on them so there is this very solid flat “pad” up at the very front Stbd/Right side of the massive cast aluminium crankcase with three good size mounting studs so that’s where I’ve designed a mounting system to be.
PXL_20201104_133928567Here is the top mounting bracket I came up with all ready to bolt onto that “pad” in the photo above.  Not quite up to Gardner standards perhaps but I assure you it will last as long as Mr. Gee will, aka forever!
PXL_20201104_134454292Difficult to photograph for you but this is what the test fit assembled mount looks like.  The thick AL plate at the top is what is bolted to that pad you saw above which then has the tall thick vertical AL mounting bar bolted to it at the top and an L-bar bracket for the bottom support where I used three bolts on the Sump (oil pan) to hold the bottom of the mounting bar.

The Jabsco sea water pump will bolt about half way along the length of the mounting bar and will be driven by a timing belt type of rubber belt off the Gardner’s crankshaft which you can see off to the mid right side of this photo.

Here is a different view from up above.

The big cast bronze housing is the engine oil heat exchanger which just clears the AL top plate of the upper mounting plate.

The large round cast AL item on the bottom Left with the copper tube snaking upward here is Mr. Gee’s coolant water pump that is internally driven off the camshaft.
PXL_20201104_134527744For the curious and observant of you, the large diameter black disc resting on the crankshaft is the chainwheel for Mr. Gee’s hand start cranking system which I will show you more of later.
OK, that’s it for this week folks.  Sorry it is so short and that we get a much longer work week this week and have more to show you in the next Möbius.World Progress Update Show & Tell.  Christine and I have had a VERY busy weekend and all day today (Monday) helping out two other couples who may become future new XPM owners.  One couple via a lengthy video call (thanks Andrew & Lili) and the other couple who are long time circumnavigating sailors who are here in Turkey for the winter and drove over to spend the weekend with us here in Antalya to meet the people at Naval Yachts and get a full tour of the Free Zone and Möbius.  We had a great time with Wade & Diane who have such a similar history as Christine and myself and we have just said goodbye for now as they head back to their boat which is about a 3 hour drive West along the coast to Alanya.  Great to meet up with you Wade & Diane and look forward to more such visits.

And thanks to all of YOU who chose to join us here on the Möbius.World blog every week.  We really appreciate having you along for the ride and for all your questions and comments that you write in the “Join the Discussion” box below.  Please keep them coming, we prize them highly.


Miss Möbius Tries to Runaway from Home! Progress Update XPM78-01 Möbius Aug 10-15, 2020

Our first full 5 day work week for Team Möbius in a long time plus another full day for Hilmi and I yesterday (Saturday) so much more to share with you for this week’s Progress Update report.  Several new jobs began this week, new aluminium arrived, Mr. Gee got some much needed TLC and then we did have the “runaway” incident as per this week’s title. 

AND, compliments of Captain Christine there is a bonus surprise video embedded along the way below! 

So grab your favorite beverage and strap yourself into your comfy chair and let’s jump right into this week’s Show & Tell here at Naval Yachts.

Miss Möbius Tries to Runaway from Home!

IMG_20200812_135929Our little girl “Miss Möbius” has been growing up quickly over the past two years and based on her behavior this week I’m thinking that “boat years” must be like “dog years” as she seems to have become a teenager.  How else to explain that earlier this week she tried to make a run for the sea and run away from home?!?

Or maybe, like her owners, she just got frustrated by the ever changing Launch Date? 

Or maybe her big Nose Cone sniffed the smell of the sea blowing through the shipyard with the big winds we had on Monday and decided to make a run for it? 

IMG_20200812_134923Whatever the reason she somehow had managed to conspire with her new best friend, 56 Wheeled Wanda, the second biggest boat mover in the Free Zone, to come pick her up and they were headed out the door when Captain Christine caught wind of their plan and tried to block them from leaving.
IMG_20200812_135121Alas, the barn doors were wide open and there was no stopping them and they were off and running for the sea.

OK, OK, just kidding. 

IMG_20200811_133746The real reason is that a big new refit and stretch job on a 36 meter/120 ft yacht is arriving at Naval on Tuesday and they need the entire length of the bay Möbius has been in so they needed to move us out and over to the opposite side of the shipyard.
IMG_20200811_133800We’ve been storing all the major equipment yet to be installed down on the floor underneath Möbius so that all had to be moved first.
IMG_20200812_100209Everyone pitched in and the forklift helped out and it was soon all clear below.
IMG_20200812_114233Uğur and Nihat put in four longer supports that went all the way up to the rub rails so they could cut off the shorter ones to give room for …………..
IMG_20200812_120057………..  52 Wheeled Wanda to slid her two rails full of hydraulic jack stands all the way under the anxiously awaiting Miss Möbius.
IMG_20200812_121342Each dual set of wheels have one set of hydraulic cylinders that can turn them to a very steep angle that allows them to move the boat sideways.
IMG_20200812_135132Every other set of axels have their own hydraulic drive motors built into their hub to power the wheels forward or back.  The two side rails are locked together using the big cross tie rails you can see here.
IMG_20200812_134934The whole boat mover is completely self contained and this single diesel motor powers a very large hydraulic pump pushing high pressure hydraulic fluid down all those steel lines you see extending down the upper area of the side rails.
IMG_20200812_140751And all this is run by a radio remote control unit that you can see hanging from the neck of Wanda’s operator standing on the left of Nihat here.

IMG_20200812_160134And just like that, the whole bay is now empty and ready to be VERY fully filled up with the new 36 meter job to take its place this coming week.
IMG_20200812_142020We couldn’t stop Miss Möbius entirely but we were able to thwart her escape and redirect her back into the shipyard two bays over and what should be her new home until it really is time to have Wanda help us take the fully finished Möbius to the sea!

Now the moving process is reversed and the steel stands are moved back in place under the length of the central Keel Bar to support Miss Möbius so that Wanda can set her down and leave.
IMG_20200812_155358The side stands are welded back in place and the concrete floor is drilled for long steel pins and lag bolts to keep her upright.

And we can say “Bye Bye, See you soon” to Wanda until we need her again on Launch Day.
IMG_20200812_155934Möbius’ new “bay mate” is “Twinity”, a 20 meter/ 65 ft catamaran who’s height and width make Möbius look positively diminutive but she’s the Just Right size for us.
MVIMG_20200812_161808For some perspective and sense of scale I shot this photo looking the length of the shipyard from one floor up in my Workshop.  Möbius used to be in the empty bay on the very far Right here and now sits in the background by the big bay doors.  the other ship tented in plastic in the foreground is “Caledonia” an all steel sailboat that should have her launch date next month sometime.
IMG_20200813_100357Up on Möbius for the first time in her new home, we hope that she is a bit more content with her big nose cone as close to the doors as possible so she can keep enjoying those fresh breezes blowing in from the launch harbour a few block away.  And hopefully no more than a few months away!!!!

But Wait!!!!            There’s more!!!!

We have heard all your many requests to have more video content of this whole process and so Captain Christine has been spending a lot of time in the past month getting up to speed on some new video editing software she really likes and she will be using this to create some more video for us to post here with all the “spare time” she has between the 7 day work weeks we are both logging to try to get Möbius finished and launched.

We both did our best to shoot some video of Moving Möbius and so here is a time lapse video Christine just put together.  Hope you enjoy it.

Antennae Arch

IMG_20200811_165635New aluminium arrivals mean new jobs so can you guess what this pile of pipe is for?

Two new jobs actually, first as you’re about to see is building the new “mini arch” or Antennae Arch that sets atop of the Main Arch to provide a “roll bar” kind of protection around the 2m/6.5’ open array Furuno FAR1523 Radar antennae and also provide all the real estate for the myriad of different antennae, GPS, weather station, satellite compass, search light, etc..
IMG_20200814_170152With all the various roles I’ve taken on for the build in the past few months, time is in limited supply so I just created this quick hand sketch of the design I came up with for the new Antennae Arch and the critical placement of each bit of kit that mounts on it. 

Antennae Arch list of equipmentI’m not sure how legible this will be (click to enlarge) but here is the list of each numbered item on the Antennae Arch.

Designing this Antennae Arch and the placement of each item is perhaps one of the best examples of how much compromise is a big part of design in that almost every one of these items has its own quite strict set of requirements for placement relative to how high it is, how much above/below its neighbors, how close to centerline, etc.  Of course most of them would like to be an “only child” and be the highest of them all with no one else nearby so you quickly realise that you just have to prioritise each item’s requirements and then do a triage type process of putting each item in the best position possible. 

Christine and I spent two days putting our heads together to come up with this eventual layout and I’m sure it could be improved upon even further but we think this is at least good enough for now and we will see how it all works in the real world once we launch and start using all this equipment and we can make changes from there.  We’ve had a list for what we call “Rev 2” and “Rev 3” with the changes or improvements we would like to make in the coming years so we’ll just add these to those lists.

IMG_20200813_093940Once they had Möbius moved Nihat and Uğur dove right into that pile of pipes and elbows and started to build the Antennae Arch. 
IMG_20200813_094015The elbows needed to be altered a bit as the angle of the corner of the arch is greater than 90 degrees so that’s what Nihat is up to here.
IMG_20200813_132807The ends of each pipe and elbow are bevelled to create a deep V for maximum penetration of the weld and then tacked in place.
IMG_20200813_132818The first of the dual mini arches that will be built to match the Main Arch they will be welded to the top of.
IMG_20200813_171018Like this.  We are using this ladder type construction in several places on Möbius; the Main Arch as you have seen for a long time and now this mini-arch that goes on top and soon you will see this same construction on the second new job that some of this new aluminium pipe is for, but I’ll keep that for next week.

IMG_20200814_101355We went back and forth on whether to just have the interconnecting ladder pipes all the way across the top or to put in a solid plate and decided that the plate was best as it creates a well protected wire chase to run all the many  wires and co-ax cables from all the antennae and other equipment.
IMG_20200814_121831Uğur has framed in the bottom for two plates that will be bolted and sealed in place to help protect the wiring further.
IMG_20200814_163823And here is the completed Antennae Arch.
IMG_20200814_170133Yusuf on the far Left, Nihat and Uğur and I then put our heads together to work out the details of all the different mounts that need to be created for each item on the Antennae Arch.
IMG_20200814_185903With so many different antennae and items to be mounted on this Arch, the numbering of each item was very helpful to keep them all straight and provide an easy shorthand for what was what.  This is where we finished up on Friday so I will show you the whole antennae farm next week.

Nogva CPP Propeller Blades

While everyone else was busy prepping to move Möbius I took on the other job that needed to be done before the move which was to reassemble the Nogva CPP propeller blades. 
Nogva CPP removal hole in rudderYou may recall from previous posts many months ago that we removed the CPP (Controllable Pitch Propeller) blades and hub when we were cutting the hole in the Rudder that enables us to remove the whole prop shaft without having to remove the Rudder.
Nogva CPP hub disassembledNow the whole CPP propeller hub & blades needed to be reassembled now which is a fairly straightforward process as these CPP mechanisms are eXtremely simple but they are also very high precision fit and have critical rubber O-ring seals that need to be put in place just right.
Nogva prop blades removedEach of the four prop blades are a single piece CNC milled from a solid billet of special bronze alloy which weigh about 20kg/45 lbs so they are a bit unwieldly to handle and get them to slide into the high tolerance fit into the hub.
IMG_20200811_151915Like this.
IMG_20200811_151935Uğur helped me in the beginning until he had to go look after moving Möbius so we thoroughly cleaned each part, put on a lots of new grease.
IMG_20200811_151946Fortunately, there were two excellent student interns working at Naval this past month, Omer on the Left and Alp on the Right, and they were eager to learn about how CPP props work so they joined in and helped wrestle each very slippery and heavy prop blade into position.
IMG_20200811_163533If you look closely in the photos above (click to enlarge any photo) you can see that each prop blade fits into a slot in the hub so they can’t fall out and will stay in place once they have been fully slid into place.  Then the hub end can be slid in place to capture the other half of each blade and this is then torqued down with some thread locker on each of the 8 bolts.
IMG_20200811_163521And Voila!  Miss Möbius has her CPP prop all good to go.
IMG_20200811_163546Viewed from the forward side looking aft you can see how there prop shaft itself is fully enclosed within the outer aluminium collar with the holes in it which thus prevents any errant ropes or fishing nets from wrapping around the prop shaft.  The holes are where the water injected into the far forward end of the prop shaft exits back to the sea and keeps the prop shaft fully protected by fresh seawater inside the prop shaft log tube.

Kobelt Hydraulic Steering Oil Tanks

IMG_20200810_181444Last week we covered Uğur and Nihat building the two header tanks for the hydraulic oil supply to the Kobelt steering pumps.

This is the larger of the two tanks which I designed to hold about 52L/14 USG of oil to keep these two Accu-Steer HPU400 auto pilot pumps well fed and I was able to design it to fit just perfectly into the space above these pumps.
IMG_20200810_181449This is a combination sight gauge and thermometer that makes it quick and easy to check the temperature and level of the hydraulic oil inside.
IMG_20200810_181505And we recessed this filler pipe and vent cap into the wall on the hinge side of the Watertight door from the Swim Platform into the Workshop so it is easy to access but not in your way as you walk in and out.
IMG_20200810_181858This is the small little 1.5 liter header tank on the Left that keeps the bronze Kobelt manual steering pump on the Right full of hydraulic oil.
IMG_20200815_104543I was able to design this tank to fit nicely into the space underneath of the Main Helm Dashboard which hinges up out of the way for access and Cihan soon had this tank all mounted and plumbed into the Kobelt hydraulic system.


IMG_20200813_095718Speaking of our head Plumber Cihan, he was back on Team Möbius this week thankfully and was busy installing several other systems on Möbius including the equipment for the shower on the Swim Platform.
IMG_20200813_095712Christine had picked up this very high quality bronze mixing valve at Ikea and Cihan soon had fabricated a bracket and mounted it up above the top of the Haz Mat locker where it will be super easy to access when needed yet well protected from the elements when not in use. 
IMG_20200813_095709Next week he will finish plumbing the Red/Blue Hot/Cold PEX water lines and the hand held shower wand.  The large White wrapped hose is the supply for the Fire Hose that will also live here inside the Haz Mat locker.
IMG_20200810_181640These long delayed Whale Gulper 220 Grey Water pumps finally arrived so Cihan was busy installing one of them in the Forepeak and one in the Basement where they will be used to pump out the contents of the Grey Water tanks to the exiting Sea Chests. 
NOTE:  In practice we don’t use these very much as we almost always let the Grey Water from showers and sink drains go straight back to sea but when we do use the GW tanks in a marina for example, these pumps let us empty them next time we are out at sea.

IMG_20200810_181717Cihan also had time this past week to finish plumbing both of the VacuFlush toilets.  This one is in the Guest Head and is now fully plumbed for the Fresh Water flushing water and supply water for the Bidet as well as the exiting Black Water.
IMG_20200810_182053Ditto for this one in the Master Cabin Head. 

These are both quite exciting milestones for Christine and me as they represent a new stage of the build as we move into such finishing work.
IMG_20200811_133017And just outside the Master Head the pièce de résistance of Cihan’s work this past week was the installation of this bit of beauty; our Vanity Sink at the very front end of our Master Cabin.
IMG_20200811_133025This unique sink is made from a solid clear glass casting which then has a iridescent coating of these beautiful blues.  The drain cap is still wrapped in its protective film so it is normally adding its glimmering polished stainless steel glow to the whole look.
IMG_20200811_133035And we think this faucet we found is equally unique and the perfect Goldilocks match for the sink it supplies.

There is a matching rectangular version of this sink and faucet in the Main Head/Bathroom where the all White walls create a complimentary yet different look.  Can’t wait to see and share that with you in the next week or so once the Corian countertop is installed in the Head.


IMG_20200810_182044Back on the other side of the Vanity Sink the White gelcoat cabinetry is also getting closer to being finished.  Bottom doors are now mounted on the Blum hinges and the countertop awaits the Corian that we hope will arrive in the next week or so. 

The removable Teak floors for this Head and Shower as well as the Guest Shower are being finished up as well so I hope to be able to show you them being installed next week.
IMG_20200811_130604Moving Aft to show you the recent progress in the Corridor which connects to the Guest Cabin off to the Left outside of this photo and then through the WT door into the Workshop and Engine Room in the upper Left background.

The area on the Port/Left Hull on the far Right of this photo will be my Office and “clean room” workbench which now has this gorgeous hunk of Turkish quarried Turquoise marble now in place.  We ended up with a double order of this fabulous marble so I decided to use some of it in place of the Corian countertop we had originally specified.  Should make an eXcellent working surface for me with plenty of storage drawers and cupboards above and below.

IMG_20200811_130627Seen from the other end just inside the WT Workshop door, you can see the large Aft Electrical panel full of circuit breakers for all four voltages; 12 & 24VDC and 120 & 230VAC is on the far Left side of the stairs leading up to the Galley and SuperSalon.  This electrical panel will eventually be enclosed with an large labelled front panel and a hinged Rosewood and glass door.
IMG_20200812_100651Upstairs looking Aft at the Galley, Omur has continued his relentless work to complete all the Rosewood cabinetry throughout Möbius. 
IMG_20200812_100712In front of the Galley our Dinette Settee is also nearing completion.  Next up will be building and installing the large table here.  That will be fun to show you as it moves in all three axis; Up/Down Z axis as well as fore/aft X axis and side to side Y axis as well as able to be rotated in any of these positions. 
Might sound excessive but it is “little details” like this which add so much joy to our lives when we are able to get things like table height and position just right, just for us as we use this table for everything from our main dining table, an office table for the two of us, a coffee table when relaxing and a bed when we have more guests than our cabins can sleep.

IMG_20200812_100704If you can see through the clutter of the work going on here you can see how this forward end of the SuperSalon is also starting to take shape.  The large Rosewood slotted panel on the far Left will be hinged inside the opening behind it where the 50” SmarTV mounts. 
Helm Chair goes in the center of the Main Helm where all those wires are being tamed and then the stairs down the Master Cabin on the far Right.


IMG_20200815_104713As you can see, Hilmi has also been making good progress with his electrical work at the Main Helm.  This week he and Selim have been busy wiring up the switch panel on the angled wall above the Forward Electrical Panel as well as the various controls mounted in the Dashboard of the Main Helm.
IMG_20200815_104701The Furuno 711C AutoPilot control head is under that Gray protective cover in the center of the Dashboard with the Jog Lever to its Right and then the dual Kobelt control levers for Throttle and CPP Pitch on the far Right with the round Prop Pitch gauge above.  Maxwell windlass control above the Jog Lever and the empty hole soon to be filled with the Vetus Bow Thruster joystick and the ACR Pan/Tilt searchlight in the upper Right corner.
MVIMG_20200815_155106Lifting up the hinged Dashboard reveals more of Hilmi’s work as he starts to connect all those items as well as filling the Grey wire chases with the many wires that need to traverse from one side of the Main Helm to the other.
IMG_20200815_155257This “handkerchief” triangular storage area is on the Port/Left side of the Main Helm with a matching on on the opposite side.  We intend to use this one for a central Charging Station for the growing list of wireless electrical items that need charging.  
IMG_20200815_155252The two black panels you see in the back of this storage area are blocks of fused 12 & 24 VDC connections using Anderson PowerPole connectors to give us a single standard for all our 12 & 24 volt connections.

The rectangular hole is for the 120 & 230VAC receptacles.

IMG_20200810_181936More progress inside and behind this Forward Electrical Panel on the Right side of the Main Helm with the addition of the white mounted shunt, one of three, which is required for measuring current amps in this panel.
IMG_20200812_100406Above the Fwd Electrical Panel Hilmi and Selim completed most of the wiring of the switchboards up on this angled top.
IMG_20200812_100412The underside of the lower switch board shows the ready access to all this wiring.
IMG_20200812_100432Top side shows the layout of all these switches.  They are divided into the upper12 switches that control the High Water evacuation system which we hope we never need to use but is in just the right place here at Command Central if we ever do need it.

The bottom set of switches are for the exterior lighting and the labels should make that all self explanatory.

The uppermost switch panel has all the switches for controlling the Kobelt steering and propulsion equipment.
MVIMG_20200812_180016To the untrained eye this may still look like a Medusa hairdoo but for those who have been following along and know wiring this is a “Beautiful Mess”!

IMG_20200812_180001Still in the early stages of wiring all these switches but Hilmi’s skills and attention to detail is already emerging on these two switch panels.
IMG_20200812_180051Always a Team effort so Omur installed this multi pin socket into the top of this Rosewood switch panel where the Kobelt WalkAbout handheld remote control plugs in.  A metal cap threads onto this socket when not in use.
IMG_20200812_180048For a much more finished look, rather than install this receptacle from the top we decided to have Omur recess it in from the bottom with this mortise. 
IMG_20200815_104451This will give you an early idea of how these three switch plates will look in the end.
IMG_20200812_114134And finishing up with this weeks electrical progress, the aft depth sounder has now been mounted inside the aluminium fairing block you saw Uğur making and welding in place a few weeks ago.  This is the Airmar 600 Watt 520-5PSD transducer which provides the raw data of the bottom below us to the Furuno BBDS1 Bottom Discriminating sounder which gives us detailed graphics of the contours and material below us.

IMG_20200811_131003Uğur and Nihat were also able to get to this small but important job of providing external access to the inside of this Port/Left side Vent Box on the Aft Deck.  The White plastic fitting below its mounting hole provides an easy to remove but fully sealed opening that I can reach through to ……
IMG_20200811_130956…… access this shut off air damper on the Air Supply into the Engine Room.  Normally this shut off is fully automated and controlled by an thermostatic switch that closes this damper when the engine is off or if there were to ever be a fire in the Engine Room.  However in case this electrically automated motor should fail, you can activate this damper manually.
IMG_20200811_131010Peering down the 3 meter rectangular supply air duct into the Engine room to show where this damper is bolted to the top.

Same damper setup is on the opposite side Vent Box for shutting off the Exhaust Air extraction vent.

Putting Humpty Dumpty (aka Mr. Gee) Back Together Again!

Another exciting milestone this week was that I finally started to put all of Mr. Gee’s bits and bobs back together again.  After many months of doing all the prep work of cleaning, replacing, rebuilding, painting , etc. I was finally able to start actually assembling all those parts and putting Mr. Gee back together again in his better than factory new condition.

I know this is not of interest to many of you so feel free to skip ahead to the end while I take the others on a quick tour of Mr. Gee’s transition.

IMG_20200810_200741As you can see Mr. Gee is now all painted in his final colours of Burgundy Red for all the cast iron parts and silicone based aluminium paint for all the cast aluminium parts.
IMG_20200810_163411This past week I was able to tackle the next metal parts; all the copper and bronze pipework which transports all of Mr. Gee’s  the coolant water and oil to where it needs to go.

As you can perhaps tell from this photo I started by using paint removing gel and then sandblasting all these parts thoroughly to remove the almost 50 years of accumulated paint, grease, oil and dirt.
IMG_20200810_163403I considered going with the quite nice matt lustre left from the fine sandblasting sand but after some experimentation I decided that a brighter look left from wire wheeling the copper and brass, which you can see the beginnings of here, was more in keeping with the finished look I thought most befitting of Mr. Gee and Möbius’ Engine Room.
IMG_20200810_163356So I brought out my full compliment of WMD’s, Weapons of Mass Denuding, including wire wheels of various sizes in my angle grinder, benchtop grinder and Dremel tool and spent several days and knights bringing all these copper pipes and their bronze end fittings to an even bright lustre. 
IMG_20200810_200838Keeping this beautiful bright look was the next challenge as copper, brass and bronze all tend to oxidize quite quickly and loose this look.
IMG_20200810_200758So I cleaned them all up with acetone to remove all the leftover grime from wire wheeling and my fingerprints, hung them all from poles spanning the ceiling of the paint booth I had created and sprayed them with 2 separate coasts of clear AlexSeal polyurethane which I have had great success with for many years.
IMG_20200810_200803The photos fail to capture how great this clear coat worked but I am eXtremely pleased with both the look and how well protected these surfaces all are now and for the next few decades.
IMG_20200810_200830If you were here last week you might remember that I had given Mr. Gee himself two coats of the same clear polyurethane so he too is now very nicely all plastic coated. 
IMG_20200812_185451While much of this is just cosmetic there is a very real pragmatic benefit I’ve found with having such surfaces on my engines and mechanical parts which is that I can see any leaks or even loosening nuts SO much sooner and these surfaces are all SO much easier to keep clean so I was quite willing to put in all this extra time, effort and expense. 
IMG_20200812_185458Plus, quite frankly, Mr. Gee and me are worth it! Winking smile
IMG_20200813_110640A few weeks ago I had found the time to clean and paint Mr. Gee’s massive, almost 150 Kg flywheel so I had Uğur lift it up to my Workshop using the forklift
IMG_20200813_110647Where I could then use my handy dandy 2 ton hydraulic lift to finally install the flywheel on the end of the crankshaft.
IMG_20200813_211015Which in turn let me bolt the outer flywheel housing onto Mr. Gee.

IMG_20200813_123649Next week we will move Mr. Gee onto the Aft Deck of Möbius where I can then bolt the Nogva CPP Gearbox to the SAE1 flywheel housing to complete the full propulsion package.  You can see the SAE14 flange I have now bolted to the flywheel and each of those inner semi cylindrical cogs will mate with the rubber drive ring on the Nogva Gearbox.

IMG_20200813_211010When I was cleaning and painting the flywheel I masked off the six sets of markings on the outer circumference of the flywheel and now you can see why. 
This little window on the top of the flywheel housing allows me to precisely set Mr. Gee to TDC (Top Dead Center) for each cylinder which you need to do to set the exact timing of the open/close of the valves and the timing and advance of the fuel injection.

IMG_20200814_163043Now the fun begins as I carefully remove all the masking taped areas and started installing things like the two cast aluminium valve covers, upper cast aluminium water manifolds on each cylinder head and the single manifold on the bottom of the cylinder block.
IMG_20200814_182853Followed by the Intake and Exhaust manifolds on this same Starboard/Right side of Mr. Gee.
IMG_20200815_180259Test fitting the dual thermostat housing on the end of the front water manifold and the coolant header tank.
IMG_20200815_180237Next week I hope to start populating this Port/Left side with all its gear including the whole fuel pump and injection system which mounts to those two circular clamps you see here. 
BTW, for those who would find it interesting, this is Mr. Gee’s “service side” where you do most of the day to day work when starting and maintaining him as this is where things like the decompression levers, fuel priming levers, water pump, fuel pump, oil dipstick, temperature and pressure gauges for oil and coolant, etc.  Hence this is the side where I located the door into the Engine room and have the most access on this side as you will soon see when we mount Mr. Gee into his new home and Engine Room.

If you made it this far I hope you took my advise to get a good beverage and comfy seat or you stopped along the way to do so.  I really do appreciate you taking the time to follow along and join Christine and I on this latest adventure and we both look forward to getting your feedback with the questions and comments you put in the “Join the Discussion” box below.

See you again next week I hope.


We are Floored! XPM78-01 Möbius Progress Update July 27-31, 2020

It is Monday August 3rd here in Antalya Turkey and everyone is enjoying the last of this big four day Kurban Bayrami Holiday weekend.  Tomorrow is also our anniversary so Christine and I decided to join in and take a much needed break from boat building so we rented a car and drove East along the coast to the lovely town of Alanya for two nights away.  It has been a fabulous break and we are now back and I’ll do my best to get this week’s XPM78-01 Möbius Progress Update off to you at last with apologies for the delay. 

This will be a shorter update due to both having only four working days last week and also due to the launch of the GreeNaval 60 hybrid boat “Mega-Guard”.  This was a long overdue milestone for both Naval Yachts and Mario the owner as this build began a few months before Möbius so this launch has been three years in the making and it was all hands on deck at Naval Yachts to splash Mega-Guard this past Wednesday.  I’ve got some photos of that big event as well as this weekly update on the progress aboard Möbius so let’s jump right in.

Mega-Guard Splashes!

GN60_T9134_Snow_WhiteThe GreeNaval 60 or GN60 is an all aluminium 60’/18.25m diesel electric hybrid yacht which has 2x 370 HP Volvo Penta diesel engines and 2x 150 kW electric motors. GN60, which offers 16knot cruise speed with diesel option can achieve 11,5knot cruise speed with electric motors.  This GN60 brochure will give you more photos and details if you are interested in learning more about the GN60.
IMG_20200729_111429Getting her first full shot of sunshine on her bow as Mega-Guard emerges from the Naval Yachts shipyard this past Wednesday.  She is setting atop one of three such boat moving machines that are on call within the Antalya Free Zone and as you can see this one can take much longer and larger boats onto its all hydraulic controlled bed.
IMG_20200729_111209Looking out of my first floor Workshop/Office inside the shipyard this is the view from the other end as the boat mover starts the several block trip over to the launching equipment at the launching basin within the Free Zone.
IMG_20200729_123459While the boat mover goes slowly it takes less than 30 minutes to make the trip from Naval Yachts to the launching basin.
B0FA5251-563C-464B-8113-9E4AF6BDDF1FNext, the big Blue Travel Lift straddles the boat mover and lifts the GN60 up within its slings and moves her over to the launching basin.

7245D915-5BFC-482A-8A45-F806DD9576E6And what do you know?  She floats!

DA31BFBF-0EFE-40E2-A185-3B9F3441AC3AMega-Guard is all the more special being the new prototype and test bed for Praxis Automation Technology based in the Netherlands.  Praxis technology is usually found in very large shipping and other commercial vessels but they are now offering equipment for smaller boats in the 18-40m and recreational range so they wanted to have this real world testing and demonstration laboratory and she leaves Antalya on Thursday bound for Rotterdam and then on to Praxis HQ in Leiderdorp NL.  We wish Mario and Praxis our very best and hope to be anchored with them in the near future.

We Are Floored!

IMG_20200727_100210This week’s title is in reference to the multiple places inside Möbius where the flooring has begun to be laid.  The majority of the interior flooring will be interlocking planks of industrial vinyl flooring made by the big Turkish company Ado and you can see a sample of the White/Silver “Aperta 2010” colour we’ve chosen HERE on the Ado website.

One of the key features that makes this vinyl flooring the Goldilocks just right flooring for XPM78-01 Möbius is that it has a significant amount of texture on the top surface which I’d describe as similar in appearance and texture to that of well weathered wood.  This a critical safety factor for us to ensure that even when walking with wet bare feet there is no slippage.
ADO_SPC_LayersThis LVT or Luxury Vinyl Tile as Ado refers to it is primarily aimed at very high traffic scenarios such as airports, shopping malls and the like and it is also 100% waterproof, fireproof and extremely quiet when walked upon. 

It is also specifically designed and engineered to be used overtop of In-Floor heating systems such as the ones we have installed in Möbius.
IMG_20200727_182532The Flooring team chose this area in the Head/Bathroom of the Guest Cabin to begin to cut and fit the individual planks of LVT and are just getting started but this will give you a good idea of how these interlocking “click-lock” planks are laid down. 

In order to access the integral fuel and water tanks below all our floors, there are aluminium tank access plates bolted down throughout such as the one you can see here in the middle of the photo partly obscured by the Rosewood sink cabinet.  The flooring overtop each of these hatches will be removable and will be secured by a special SS twist lock device to ensure that these access squares can not fly out in the unlikely event of a full roll over.
IMG_20200728_094347Directly across from the Head is the Guest Shower and it is having its all composite based flooring installed which is the same material as all the walls and ceiling so everything is fully bonded and sealed.

Same style of lift out section to get at the tank access lids below the shower floor.

The aluminum suction tool in the foreground is how we lift out flooring hatches, wall panels and the like and works eXtremely well.  No unsightly handles required, simple, quick and easy to use.
IMG_20200728_094404Once the flooring was fully cured the pre-installed drain was routed out for the SS drain fitting to be installed flush with the floor which slopes down to this point.
IMG_20200729_124941The finished floor in both showers will be made of inlaid Teak as this has that just right amount of underfoot non-skid texture and is naturally waterproof.  These are two of the three sections of flooring for the Guest and Main showers and there will be a third matching one for the adjoining Head/Bathroom floor in the Master Cabin.
IMG_20200729_095435Same construction technique as is used for installing all teak decks on yachts, each individual Teak plank is cut, fit and glued to a template underneath and then once the whole panel is laid up, the template is removed and the teak panel is attached to a composite/fiberglass panel underneath.
IMG_20200729_095439The grooves between each Teak plank allow for expansion and flex and will be filled with a Black rubber like waterproof filler and then the whole panel is sanded flat. 
IMG_20200729_153507These are the two floor panels for the Master Cabin.  The longer one in the foreground will become the floor in the Master Cabin Head and the one in the back will be the floor in the Master Shower.

You will be able to see this in great detail in the upcoming Weekly Progress Updates as these floor panels are built and installed so say tuned for more.

Finishing the Corridor:

IMG_20200727_150015Just outside the Guest Head Omur has been busy deftly applying the finishing touches to the cabinetry in the Corridor area.  This is a very busy area where you make your way down the stairs from the SuperSalon above to get to either the Guest Cabin or the Workshop & Engine Room.

This past week Omur finished installing the “hockey stick” shaped Rosewood BHL or Blue Horizon Line which provides a safe, secure and eXtremely Beautiful handrail when you are transiting these stairs.
IMG_20200727_150046Biscuits are used to join the Rosewood sections of the BHL Handrail to the wall panels to ensure they are up for several decades of hand traffic.

The ubiquitous aquamarine epoxy strip spans the space between the upper and lower halves of the BHL.
IMG_20200728_175628And with a bit of ingenious clamping techniques Omur soon has the bottom section glued in place.
IMG_20200729_100008I’ve peeled back a bit of the protective cardboard and tape coverings to show you how the two halves of the BHL Handhold terminate up at the top of the stairs.
MVIMG_20200729_152724Omur has also been finishing off the cabinetry on the opposite side of the stairs where the tall Electrical Panel sits part way down the stairs and then my long skinny Office desk and storage area runs along the Port/Left side of the Hull.
IMG_20200730_135227Here is what the Corridor area looks like viewed from the stairs looking aft through the WT Bulkhead door into the Workshop.
IMG_20200729_152658Seen through that WT Workshop door you can just make out the Blue/Green leather covered Corridor wall panels on the Right side and the Office desktop and drawers on the Left.

If you have your orientation down you will know that the Guest shower is behind the foreground wall on the Right and the Guest Head is behind the wall after that.


IMG_20200727_105443Up those stairs and on the Right is the Galley and over in the finishing shop they are finishing all the Rosewood fronts for the many drawers in the Galley, some of which you see here.
IMG_20200727_105428More here ……………………
IMG_20200728_154515…… and more here.

Yes we have a LOT of drawers in the Galley and can’t wait to start filling them with food, plates, utensils and our extensive collection of kitchen tools.
IMG_20200729_100036Once they are all hand rubbed and polished, all these drawer fronts are brought onboard Möbius to be installed.
IMG_20200730_105853Which is what Omur is busy doing here to some of the drawers under the side “peninsula” of the Galley.
IMG_20200730_105941And pretty soon they all look like this bank of drawers on the opposite peninsula behind the Dinette Settee.

Temporary Blue painters tape handles for now and just wait till you see what these look like when their permanent SS latches are installed.


IMG_20200727_094741As always, the handiwork of  Hilmi and Selim can be found throughout the boat as our two Sparkies aka Electricians, continue to install the wiring and start connecting all the various electrical components together.

This is the inside of the control panel of the 40k BTU Webasto BlueCool V50 chiller.  Hilmi has removed the outer cover to make the internal connections to the boats wiring.
IMG_20200728_094148A few steps away inside the Engine Room Enclosure, the helpfully tall Selim is busy pulling wires into the ER through the penetrations you can see (click to enlarge) up near the ceiling and then securing each wire to the cable trays mounted on the Alucobond covered ER walls.
IMG_20200728_094206Those cable trays continue to run forward behind the exit manifold on this Sea Chest at the front Port end of the ER.
IMG_20200727_105125Meanwhile, Hilmi has been busy running more cables across the Front of the ER for things like the High Water pump out valves, Grey Water pumps and various tank level monitors.

FYI, Hilmi is sitting where the front end of Mr. Gee our Gardner 6LXB engine will soon call home.
IMG_20200727_100149Right here.  The two inner facing Engine Bed extensions are where the front engine feet or motor mounts will set and be bolted in place.

Engine Room Hatch Hinges:

MVIMG_20200730_111419Uğur and Nihat didn’t get much time to work on Möbius again this week as they were busy getting Mega-Guard finished and launched but they did get time to make some progress with things such as these hinges for the big Engine Room Hatch which forms almost the entire ceiling of the ER.
IMG_20200730_111424These hinges are one of the latest examples of the overarching KISS or Keep It Safe & Simple approach we try to use throughout XPM78-01 Möbius.  Uğur is very handy on the metal lathe so he quickly turned out these three hinges by drilling out three lengths of sold aluminium round bar to accept the 10mm / 3/8” SS pin he machined. 

After leveling this big ER Hatch with the surrounding deck and centering the Hatch in its frame Uğur tacks the ER Hatch in place and welds on the three parts of each hinge to the Deck and Hatch.
IMG_20200730_135350Removing the tack welds the door swings open easily and is locked in the open position using pin locks to the Vent Box on the Right here.

For those wondering why this ER Hatch is so huge, we designed it such that the complete propulsion package, the Gardner 6LXB mated to the Nogva CPP Servo Gearbox, can be lowered in/out of the ER as one single large assembly.

That won’t happen very often but WILL happen often is that I can open up this big ER Hatch whenever I am down working in the ER and have all that fresh air and natural light pouring in which will make working in there all the more of a treat.

SkyBridge Solar Panels:

IMG_20200727_145808However the most exciting bit of progress Nihat and Uğur made the past week was this!

If you were with us last week you will remember that we had lowered the roof frame over the SkyBridge to its  hunkered down position that we will use for going up canals with low bridges or when leaving the boat in locations during hurricane seasons.  Part of the reason for lowering the roof was to make it easier to install the eight 340 Watt Solar Panels which also form the waterproof roof.
IMG_20200727_181727I chose to use Sikaflex 292i which is their strongest industrial adhesive to bond the aluminium frames of each panel to the rectangular aluminium tubing that the SkyBridge Roof frame is built from.
IMG_20200727_181507Prep is always the key to a long lasting bond so all the AL surfaces were cleaned first with a wire wheel and then wiped down with Sikaflex thinner.
IMG_20200727_181700Then an even bead of 292i is laid down.
IMG_20200727_181935and each Solar Panel is then carefully set in place. 
IMG_20200727_182017We used a laser level and straight edges to ensure that each panel when in just the right position before being pressed tightly down to squeeze out the Sikaflex on all sides.  The tops and side of each panel were also bonded to each other using 292i to create a very well sealed and fully waterproof roof.
IMG_20200727_181523Using this eXtremely strong adhesive eliminates the need for any mechanical fasteners and made for a very fast installation and met with Uğur ‘s satisfaction as you can see.

In addition to these eight roof top panels, there are three more in a hinged frame on the front and three more on a sliding frame aft for a total of 14 panels with a combined total output of 4.4kWP
I did manage to make a bit more progress on Mr. Gee but I’ll keep you waiting and save that for next week’s Progress Update.

Thanks for joining us and special thanks to all those who add their comments, questions and suggestions in the “Join the Discussion” box below and I hope more of you will do the same and add to the richness of this blog.

This coming week will also be shortened down to just four days but hopefully we will have most of Team Möbius back working with us now that Mega-Guard is launched.  See again then.


TRANSFORMING BEASTS INTO BEAUTIES! Progress Update on XPM78-01 Möbius–July 20-25, 2020

A very full work week here in Antalya Turkey at Naval Yachts with no holidays this week but a BIG four day holiday weekend coming up next week.  Weather continues to be sunny and summery with daytime temps in the 34-38C / 93-100F but humidity seems lower on what is now our third summer here and with a beautiful big pool right outside our front door we are enjoying the weather AND the progress on XPM78-01 Möbius.  So let’s jump right into this week’s Show & Tell so you can see for yourself.

SuperSalon In-Floor Heating PEX Installed:

One of the last big jobs on the ToDo list for the SuperSalon which is to install all the loops of PEX tubing for the In-Floor heating system.  The Master and Guest Cabins already have all their PEX lines installed to the SuperSalon was the last on the list and this week’s first Beast to be transformed into a Beauty.

IMG_20200722_183142Being central to the whole boat, the SuperSalon area gets the most about of daily traffic so we waited till now to take on this job as it requires removing all the marine plywood flooring in order to get at the rigid foam underneath and cut all the U-shaped channels for the 15mm PEX tubing to snap into.  Not too much of a Beauty just yet, but watch …..
IMG_20200722_181655Knowing they would all need to be removed, Omur and Selim had just put in a few screws when they installed all the plywood flooring so it didn’t take Omur too long to remove all the plywood.
IMG_20200723_175352Before he left to go serve his military time, Yigit and I created these layout drawings for the circuitous routing of the continuous 15mm / 5/8” PEX tubing.  It takes a bit of planning to ensure the radiant heat is being distributed in the right amounts for each different part of the Helm, Galley, Lounge, Dinette and Entryway and maintain the 120mm/4.7” minimum bending radius.
IMG_20200723_095404Omur transferred the layout to the foam and quickly cut all the U-shaped grooves in the foam with a small handheld router.
IMG_20200723_132118Next step also goes quickly which is to press aluminium foil tape to line the inside of the grooves to help reflect the heat upwards into the plywood and eventually out the finished vinyl flooring.
IMG_20200723_161801Like this.  The area in the foreground is where our two reclining Eames lounge chairs will go so the PEX tubes are places a bit closer together for slightly more heat in this area on colder Antarctic nights. 

Hmmmm, so Wayne, that would be compared to all the WARM Antarctic nights?? Winking smile
IMG_20200723_175200Here is the PEX layout in the Galley with the Red PEX tubes now press fitted into their foil lined grooves and ready for their plywood floors to be reinstalled.
IMG_20200723_175152Looking to Port/Left side of the boat where the two large Refrigerators sit you can see where the PEX tubes enter and leave the SuperSalon.  Where the PEX tubes pass under this cabinet they are additionally insulated with slip on EPDM sleeves and then the space of the drawer above further ensures that no heat travels upwards to the bottom of the eXtremely well insulated Vitrifrigo fridge box.
IMG_20200723_175225Behind the Fridge cabinet the PEX tubes make a large radius bend down through the AL penetration in the floor at the top of this photo, where they go down into the Basement and connect to their circulation pump on the In-Floor heating manifold.

Next week the support brackets for these two PEX tubes will be added and the EPDM insulation tubes will slip over each tube from where they enter this area behind the Fridge Cabinet at the bottom of this photo.
IMG_20200723_175348Hakan lent a hand to Omur and they soon had all the 12mm / 1/2” plywood screwed securely to the White epoxy covered foundations.

The darker square in the upper Right floor area is the solid foundation for mounting the Main Helm Chair pedestal.

IMG_20200724_094459Feels great to see the SuperSalon reach this new degree of completion.

Still very much like me “a diamond in the rough” but to my eyes at least the multi coloured “Beast” that you saw in the first photo above has definately been transformed from Beast to Beauty and there are more to show you later as well.
IMG_20200724_153643Not to to give away too much, here is a sneak peek at a few planks of the 5mm thick click-lock that we are using for the finish flooring throughout XPM78-01 Möbius. 

This vinyl plank flooring is made by the huge Turkish flooring company Ado and you can see a sample HERE.

This flooring is used in places such airports and other high traffic areas so it is eXtremely durable and 100% waterproof.  We have also tested it for a Goldilocks just right about of wood grain like texture to make it very non-slip even with wet feet and it is specifically made for In-Floor heating.

IMG_20200724_172932Here in the Guest Head/Bathroom is the first plank of flooring to be cut and will give you a bit better sense of the nice contrast between the dark swirling grain of the Rosewood and the subtle Silver Gray “grain” of the Ado vinyl flooring.

Stay tuned for much more about this vinyl flooring as they starting installing it throughout Möbius.

Leather Ceiling Panels & Window Mullions, Doors & Drawers

The overall SuperSalon is getting more and more Super and more and more complete.  A bit difficult to see through their blue tinted plastic covering the Black and White leather clad Ceiling panels are all back from the Upholstery Shop and have been snapped into their FastMount clips which really adds to the finished look in here.

MVIMG_20200720_094728Hilmi and Selim finish putting in the crimped on connectors for all the LED lights in the Ceiling Panels.
IMG_20200724_174119Down the staircase in the Corridor Omur has started installing the drawers and doors in my long “clean room” workbench & office.
IMG_20200724_174110Lots more Blum hardware of course which you have already heard me gushing about how well they work with their soft open/close and fully hidden features which I REALLY like.  As you can see with the drawer sitting on top of my workbench, these drawers are quite shallow due to the steeply sloping hull sides behind the wall grid so the Blum drawer slides in the cardboard box are short but full extension models and you can see how these drawer slides mount completely out of sight on the bottoms of the drawers.
IMG_20200720_190034Upstairs and just back from Sinan in the Upholstery Shop are these Window Mullion Covers so Omur has been busy getting them installed. 

FastMount clips require a bit too much depth here so we are using strips of 3M Dual Lock tape which are very thin snap together strips that hold things together with no slippage.

This relatively new dual lock style fastener works similar to but MUCH better than the older “hook & loop” or Velcro.  It has 4-10 times the gripping power and it has two other differences that are the big deal to me.  The first is that that I never have much success getting the old cloth based hook & loop/Velcro to stay attached to the surface it is mounted on.  Dual Lock is all plastic so its self-adhesive backing or the adhesive you apply keeps it there all the time.

duallock_mushroomhead_graphic_small Second bit difference for me is that Dual Lock uses tiny plastic “mushrooms” which interlock as per this illustration so there is no slippage or “wiggle” and unlike Velcro, both sides are the same so any piece can mate with any other piece.
IMG_20200721_100158ACCESS to all systems, wiring, plumbing is a top priority for me and in several of these Window Pillars we are using the space inside the thick aluminium I-frames as a wire chase so I needed these leather Window Mullions to be solidly attached and yet still easy to remove.  Dual Lock is the Goldilocks solution and I had Omur also use it to hold down the Rosewood Window Sills here as well.
IMG_20200724_173049Pardon all the construction clutter but this shot will give you an idea of how the Black and White Mullions finish off the windows quite nicely.
IMG_20200721_183444More finished work happening here in the Aft Starboard corner of the SuperSalon and the staircase down to the Corridor leading to the Guest Cabin and Workshop.  Ömür’s grain matching handiwork prominently on display here where the three doors are now mounted into this wall.
IMG_20200721_133650The top two doors are Fast Mounted so they snap In/Out on the rare occasions when I need access to the hoses exiting the Fuel Fill & Vent boxes behind them.
IMG_20200721_183434Whereas the door on the bottom is hinged as this is Christine’s “Internet Alcove” where several of our internet related items will reside such as routers, hubs, switches, access points, etc.
IMG_20200725_141510Similarly great to see examples of things starting to be finished are these Ro$ewood panels up at the Main Helm Station of the SuperSalon.  Our 50” monitor mounts on the hinged panel on the Left here and the panel below the Main Helm itself is a snap In/Out panel to provide access to the hundreds of wires behind it.

And yet another Beauty emerges.

Galley Goodness!

IMG_20200722_100133More of Ömür’s grain matching goodness on display in the Galley as he starts mounting the fronts on all the drawers in the Galley Cabinetry.   Good example here of the “diversity” theme we are pursuing throughout the boat and here evidenced by the diversity of drawer shapes and sizes.
IMG_20200722_100146The only door in the Galley cabinets is this one on the Right which provides easy access to both the voluminous cupboard spaces inside as well as access to the systems, hoses and cables behind these cabinets.
MVIMG_20200722_183242Not quite done but definately getting closer and closer and yet another Beauty in the making.
IMG_20200725_142504Up next?

Installing these bits of SS jewelry aka positive Door & Drawer latches.

Taming the Electrical Beast:

Main Helm Panels

With an overall electrical system that includes 12V & 24V DC, 120V and 220V AC, more than 200 circuit breakers and uncountable miles of wires and cables of ever imaginable size, we certainly could have created a true Electrical Best onboard XPM78-01 Möbius.  Happily though, we are transforming this Beast into a Beauty with great organization, installation, labeling and routing.  Let’s go check out some recent examples of this electrical  transmogrification.

IMG_20200720_121956Starting up here at the Main Helm in “Beast Mode” are some of the cables coming up from the Basement below through two aluminium penetrations in the floor behind the rectangular opening below the Helm Station.
IMG_20200720_174948The Beast rears its ugly head again nearby with this pile of coils of wires destined to the switch panels in the angled wall to the Right of the Main Helm.
IMG_20200721_133704For those unfamiliar with such dragons, it might appear that the situation is getting worse not better as this Medusa like tangle of Red & Black wires now appears out of the jungle as Hilmi and Selim strip away the outer insulation from these 24V switch wires.
IMG_20200721_095759Rather than a whip and a chair, Selim’s taming tools of choice here are adhesive lined heat shrink and a heat gun which he uses to both seal and strengthen the mounting location of each cable where they will be zip tied to their holders as well as having their heat shrink labels firmly attached.
IMG_20200721_183536Not fully domesticated yet, but the tamed beauty begins to shine through here as these wires await their turn to be connected to their respective switches on the Rosewood panel that snaps into place here.
IMG_20200721_183542And more organization emerges down below as  these cables are routed and zip tied to their cable trays below the Main Helm.
IMG_20200725_141510Ahhhh, that’s better!  Not quite finished of course but if you compare this shot to the ones at the beginning I think you too will see that the beast is indeed being tamed.

Corridor Electrical Panel

IMG_20200721_095605Back in the Aft Stairwell at the Corridor Electrical Panel these may all be DIN certified circuit breakers but as you can see they too are more Medusa like monsters laying in wait of an innocent little Sparkie to come along.
MVIMG_20200721_095615Taming this Beast requires a slightly different set of weapons such as this hinged metal frame.
IMG_20200721_133258Omur joins forces with Selim and Hilmi and mounts the hinged steel frame,
IMG_20200720_121913inside the tall cabinet he has previously built and installed on the Right side as you descend the Aft Stairwell leading down the the Corridor, Guest Cabin and WT Door into the Workshop.
IMG_20200722_100048Hilmi takes his crack at the taming and has these three DIN Rails with 36 of the 24V DC Circuit Breakers.
With the cage, errrr I mean door, closed the front side shows a much tamer side.
IMG_20200722_182647Reopening the door, things are definately being put under strict control as Hilmi starts connecting each of the Red & Black wires from the Circuit Breakers in the door to their respective Gray DIN Junction Blocks that you may recall seeing him wire a few weeks ago.
IMG_20200722_182620Peeking up under the bottoms of these Circuit Breakers reveals a very well tamed collection of these 24V wires now all labelled and neatly tucked into their horizontal running Gray chases with their removable tops now snapped in place.
IMG_20200722_182747Doing my part to assist with the taming of these Electrical Beasts I’ve created coloured and labeled lists of each circuit onboard Möbius and printed this one with the 24V CB’s …….
IMG_20200723_095236…….. for Hilmi to use and check off as he methodically tames and wires each circuit.
IMG_20200723_131626Continuing to calm the Beast, Hilmi soon has the lower horizontal DIN Rail full of 12 Volt Circuit Breakers, mounted, wired, labelled and tucked into bed.

Down at the bottom he has now installed the three vertical DIN Rails.  Two on the Right hold 36 of the 220 Volt CB’s and the one on the Left has 18 of the 120 Volt CB’s.
IMG_20200724_094309Definately MUCH tamer panel now!
IMG_20200724_094402A numbered place for every AC wire up here and ……….
IMG_20200724_094419………  every wire numbered and placed.
IMG_20200724_094547Same well tamed set of 120V and 220V AC Circuit Breakers.
IMG_20200723_131654Still a bit Beast-like down here.
IMG_20200725_101124But it doesn’t take Hilmi too long to have these whipped into shape as well and the Beauty emerges here ………
IMG_20200725_101136……. here ………………….
IMG_20200725_101151.……. here ………………….
IMG_20200725_101227…… and here.

Well done Hilmi, Selim and Omur, you have definately transformed the Electrical Beast into a thing of Beauty.

Workshop Distribution Box

MVIMG_20200722_181941Ahhh but aboard Möbius the job of the Electrical Beast Tamers is still not done and so they take on the next challenge back on the Starboard/Right side of the Aft Workshop with yet another Medusa like mess of big cables surrounding the Aft DC Distribution Box.
IMG_20200723_131755As usual it looks worse before it looks better but your eyes can now probably see the method to the madness here as Selim and Hilmi wrestle these Red, Black and Yellow 120 mm2 snakes into their allotted spots, cut them to length and label each one.
IMG_20200723_131825With the big guys all labelled and fed through their WT cable glands the beauty of well organized and clearly labelled cables begins to emerge from the previous chaos.
MVIMG_20200724_174223Breaking out some additional taming tools such as this hydraulic terminal swaging tool that crimps the outer barrel of each zinc coated copper terminal log so tightly around the hundreds of tiny copper strands of each 120 mm2 cable that they all fuse together to form a single solid copper joint.
IMG_20200724_122421And so the taming trend continues down below as they start attaching each cable to their allocated position on the Upper Positive and Lower Negative Bus Bars.
IMG_20200723_131834These Bus Bars are definitely up for the job being made from two solid Copper flat bars measuring 10mm thick X 40mm wide which are bolted together and attached to the frame of the box with ceramic insulators.
IMG_20200724_153524For the Positive circuits where the Bus Bar is the source of their electrical energy, these beefy T-Class fuses are used for OCP, Over Current Protection of these cables.
IMG_20200724_172735Like this.
IMG_20200724_172751Down to one last Red/Positive 120 mm2 snake to tame.

IMG_20200725_100636We leave the final power connections disconnected for safety for now but the former Beast in the Workshop has now been fully converted into this Beauty.
IMG_20200725_100818So our two Electrical Beast Tamers can close the door on this Aft DC Distribution Box and take a well deserved break.

Transforming Beasts in the Engine Room Too!

IMG_20200720_121736Everyone on Team Möbius is a very skilled Beast Tamer and that certainly includes the dynamic duo of Uğur and Nihat who wrestle daily with different  Aluminium beasts.  This week they took on the installing the 127mm / 5” OD aluminium pipes that carry the exhaust gasses out of the Halyard Combi Silencer/Separator out the Starboard side of the Engine Room enclosure wall and out through the Stbd side of the hull.
combi_silencer_003This quick and dirty rendering sliding through the ER helps show the Halyard Combi up in the top Port/Left corner of the ER and how the 127mm rubber exhaust hose will snake its way down through the Stbd/Right side of the ER and then underneath the bottom of the Yellow Day Tank and out the side of the hull.
Halyard Combi labeled in ERHere’s my best attempt to show how this will be routed inside the Engine Room.

Brown line will be the 127mm / 5” rubber exhaust hose.
IMG_20200724_095321And here is how it looks when peering down from the Aft Deck.
IMG_20200721_133131As you can see from these photos this Halyard Combi really is a big fiberglass Beast!  The first part of the taming of this Beast was to build a good solid shelf to hold it solidly in the right place.
IMG_20200721_183329And this Beast has been tamed!

Halyard Combi In-Out labeled The Combi separates the wet exhaust gas & water entering from the Gardner engine and the sea water runs directly out the large pipe in the bottom and into the large angled pipe you can see here on the Exiting Sea Chest.  Exhaust gasses exit out the down angled pipe at the top of the Combi where the 127mm exhaust hose will carry it over to the wall of the Engine Room Enclosure on the opposite Right side.

IMG_20200720_121630To get that nasty exhaust gas beast out, Nihat and Uğur have welded this 127mm AL pipe through the ER wall just above the Intake Sea Chest.
IMG_20200720_121543On the other side of the ER wall that 127mm pipe on the Left exits just below the bottom of the Day Tank above.  Note too that they have already moved on to the next part of the taming which involves the matching 127mm AL pipe going out through the hull plates on the far Right here.
IMG_20200720_094117And a better shot of the exiting Exhaust Pipe here.
IMG_20200720_094048Which looks like this from the outside.
IMG_20200720_094032Close up shot from the outside.
IMG_20200721_100253For reference, I marked the position of the Waterline on the hull at three different loads. 
The upper WL will never likely happen as this is just for our computer based roll testing when every tank on the boat is fully filled.  The “Avg Load” WL is when we start a passage and have all Fuel tanks Full and about 10% in the Water tanks.  The bottom “Light Load” WL will be typical of End Passage when the reverse is true; Fuel tanks are down to about 10% for safety and Water tanks are Full to help make up for the loss of Fuel weight.

IMG_20200720_190408For those interested, here is where those same three Waterlines come to on the aft Transom.
IMG_20200724_172819Back in the ER, Nihat cleaned up the Engine Bed extensions that Uğur welded in last week.
IMG_20200725_100903These Engine Beds need to be perfectly flat and level so they are ready to receive the anti-vibration motor mounts or “engine feet” where Mr. Gee will soon be attached!
IMG_20200725_100937And while he was at it Nihat also transformed these Aft brackets where the anti-vibration mounts for the Nogva CPP Gearbox will be bolted.  On less Beast, one more Beauty aboard XPM78-01 Möbius!

Plumbing Beauties Too!

IMG_20200720_173214Cihan’s plumbing skills are in very high demand on several boats still but when he was able to he too tamed several other Medusa like Beasts on Möbius.  First up was putting in this horizontal tray across the front wall of the ER and then transforming all these snakey hoses into a well organised assembly firmly attached to the ER WT Bulkhead.
IMG_20200721_133855He routed some of these hoses over to the Port/Left side wall of the ER.
IMG_20200722_095642so he can connect them to this Piccolo like exit manifold he had built last week.and attached to the Exiting Sea Chest in the forward Port/Left corner of the ER.

Large upward angled pipe on the Sea Chest is where the water from the Halyard Combi exits out of the boat.
IMG_20200722_182945Clear hoses from some of the Aft Bilge pumps now all connected.
IMG_20200724_095358Soon followed by connecting these larger White hoses coming from the two High Water extraction intakes on either side of the center running Keel Bar and the bottom Left hose is from the sink in the Outdoor Galley above.

Another Beast is tamed and transformed into another Beauty on the Good Ship Möbius.  Thanks Cihan!

Oh No!  The Roof Came Down!

Not all “Beasts” are down below as Uğur proved when he slayed one up in the SkyBridge.  He did a stellar job of taming a real nasty beast that had emerged where the frames for the glass “eyebrow” windows surround the coaming walls of the SkyBridge.

IMG_20200722_183035This particular beast has been laying in wait for several months now but Uğur was able to masterfully use his MIG welding gun to transform this into a true Beauty.
IMG_20200722_183049He then continued to blast out the remaining removable posts that set atop the glass window frames where the removable acrylic windows will slide In/Out as needed.
And then the REAL fun began when the roof came down!

You may have seen this before but if not, here is a quick little animation showing how the SkyBridge roof folds down into what we call “Canal/Hunkered Down Mode” where the Air Draft, distance above the WL is drastically reduced for going through Canals or “hunkering down” when we have the boat out of the water in a Hurricane/Cyclone zone.

Uğur is getting ready to mount the 8 Solar Panels up on top of the SkyBridge Roof faming and also start fabricating the “mini Radar Arch” where most of our many antennae, GPS, FLIR camera, etc. will be mounted and so having the roof lowered down would make it much easier to tame all these Beasts.

IMG_20200723_160129We will soon have a proper mechanical system that will enable just Christine and I to lower and raise the SkyBridge roof but for now we did it the quick and dirty way with a temporary line we belayed from the Sampson Post at the Bow and a couple of extra bodies.
IMG_20200724_094806This is one of the temporary hinge arm braces that we put in to provide the forward hinge point of the roof.  The Aft hinge is integral to the Roof and Arch.
IMG_20200723_160516Works very well and literally only takes a few minutes.  When finished the roof will rest on the framing surrounding the SkyBridge and hold itself up but for safety now we just put some temporary wood braces down to the Aft Deck.
Here is how it looked in real time:

MVIMG_20200723_162800This is what it looks like when viewed from the Boat with the roof down. 

Sure looks a lot smaller!

IMG_20200723_175647Standing on the Aft Deck looking forward down the Port/Left side you can see how the Arch rests in the hunkered down position.  Also a good shot of approximately what the Port Paravane A-Frame will look like when deployed.

IMG_20200724_094933Looking Aft from the front area of the SkyBridge you can see how the roof rests on the Window Frames underneath.  The eight rectangular frames of the roof will soon be filled with eight 340W Solar Panels.
IMG_20200724_094958We have designed this so we can still control the boat from up in the now open air part of the SkyBridge when that is the best spot to be.
IMG_20200723_175004Nihat took advantage of the roof being down to take on a quite literal Beast of a job;
IMG_20200724_095232drilling out the big holes where the cables travel Up/Down to the overhead Arch for Radar and all the many other electronics up there.
IMG_20200725_101437All these cables will be fully protected by this Hinge assembly when the Arch is raised and locked in its normal fully up position.

Mr. GEE’s Gets His Own Coat of Many Colours

Having taken on so many new responsibilities for XPM78-01 Möbius I once again didn’t get much time this week to give Mr. Gee more of the TLC he needs but I went in yesterday, Saturday here, and got in a full day with no interruptions and made some good progress transforming some of Mr. Gee’s Beasts into Beauties. 

IMG_20200718_154901You may recall from last week that I wasn’t happy with the colour of the special heat paint that I had used on Mr. Gee’s cast iron parts such as the big cylinder block and the heads. 

I wasn’t able to find any pre-mixed paint that matched the Burgundy colour I wanted to I got some Red and Blue epoxy do DIY the Goldilocks colour I wanted.
IMG_20200718_141314After much experimentation I settled on a 10 parts Red to 1 Part Blue.

IMG_20200718_155042And mixed them together thoroughly to create my own batch of epoxy engine paint that was just right.

IMG_20200720_162720This is what Mr. Gee now looks like sporting his custom paint job.  The colours don’t come out quite right in these photos so it looks more like chocolate than red wine here I think due to the coloration of the overhead work lights.

IMG_20200720_162724However when viewed in natural light he looks like the proper British gentleman he is and I’m quite pleased with the end result.
IMG_20200720_162730I shot this gaggle of various parts that I will soon be bolting onto Mr. Gee.
IMG_20200725_135914I did the painting earlier in the week so now that it was fully hardened I spent yesterday staring to fit the larger parts such as the upper cast aluminium Intake Manifold and the lower cast iron Exhaust Manifold.
MVIMG_20200725_185014Added on the 90 degree Exhaust Elbow and the newly fabricated SS flex pipe that is where the rest of the SS Halyard dry stack pipes will be attached to carry the hot exhaust gasses over to the Halyard Combi we’ve seen being installed above.
IMG_20200725_185041One final look for this week, looking from the front down the Stbd/Right side of Mr. Gee which will help you see the nice contrast between his Burgundy cast iron parts and all his other cast aluminium parts.

One more Beauty that will soon be onboard XPM78-01 Möbius and moves us one step closer to Launch!
Whew!  Another full, busy and productive week here with Team Möbius.  hope you enjoyed this latest Show & Tell and PLEASE be sure to tell ME what you think by putting your comments and questions in the “Join the Discussion” box below.

Hope to see you here again next week.


Oh Mr. Gee; You are SUCH a Smmoooooth Operator! XPM78-01 Möbius Progress Update June 6-10, 2020

Naval Yachts is a beehive of activity this past week with a big push for launching two other boats in the shipyard.  One particularly exciting one for Naval is the the first GreeNaval boat to be launched, their GN60 all aluminium 18m/60ft hybrid electric powerboat whose build began about three years ago just before Möbius.  The second boat is a complete refit inside and out of an all steel 16m/54ft sailboat originally built in the 1980’s.  Unfortunately this means that most of Team Möbius members have been called on to work on these two boats as they are both due to launch by the end of this month but hopefully they will return soon and progress can resume on our already long delayed launch.

However the remaining Team Möbius members are literally working overtime and weekends so progress on XPM78-01 Möbius is still being made so I have lots for this week’s Show & Tell progress update so let’s jump right into all that.


IMG_20200706_093954Our Lead Sparkie aka Electrician Hilmi had Selim assisting him with pulling some more cables and wires such as these huge cables which connect the 24 FireFly Carbon Foam L15+ batteries to the Main DC Distribution Box seen here and where you may recall they left off last week.
XPM 6S4P House BatteryThe overall House Battery system is shown here and consists of four individual “battery banks” formed by connecting six of the 4V @ 450Ah FireFly Carbon Foam batteries together in Series, Positive to Neg, which is abbreviated as 6S in electro-speak. 
MVIMG_20200706_125454And here is what 6S looks like in reality when six 4V @ 450Ah FireFly batteries are connected in Series. 

* NOTE: If you look closely at this photo (click to enlarge) each of these FireFly L15+ batteries are actually TWO 2V cells inside of one case.  This is a very smart way to do things because by simply changing how those black covered copper bars are connected, each cell can be either 2V @ 900Ah OR 4V @ 450Ah, your choice.  We are choosing to configure each L15+ as you see here so I will always refer to each L15+ as a 4V @ 450Ah battery .

** TINY TECH TALK (feel free to skip over if not interested)

Series vs Parallel connections:

Each of these four 6S banks are subsequently  connected in Parallel, Positive to Positive, Neg to Neg, abbreviated as 4P so the total House Battery is 6S4P:

  • 6S = 4V x 6 = 24Volts @ 450Ah
  • 6S4P = 4 x 450Ah = 1800Ah @ 24V

When connecting batteries in Series the VOLTS of each battery are added together while the amps stay the same so each 6S bank is

  • 6 x 4V cells = 24V @ 450Ah.

As per the House Battery schematic above, the four 6S banks are then connected together in Parallel or 4P where the AMPS are now cumulative and the Volts stay the same so the total House Bank is abbreviated 6S4P and totals 4 x 450Ah = 1800Ah @ 24V.  Volts x Amps = Watts so that equates to 43.2kW aka a LOT!

Protecting Wires vs Consumers:

Fuses and circuit breakers can be used for two very different purposes depending on WHERE in the circuit they are installed.  if they are installed at the very beginning of the power SOURCE such as a battery or inverter, then they are protecting the WIRE from what is known as Overcurrent Protection.  If the fuse is instead installed close to where the consumer or appliance is connected then they are protecting the Consumer/Appliance.  It is possible to have one Fuse/Circuit breaker do both by installing it at the very beginning of the circuit aka power source but this means that the amps would need to be the SAME for both the total amps carried by the wire AND the total amps required by the consumer.  Therefore  this only works in the case where the whole circuit is serving just one individual consumer so that the amperage rating of the fuse matches both the limits for protecting the wire and protecting the consumer.

IMG_20200706_152526Putting all that theory into practice, let’s take a look at the case of fuses used for Overcurrent Protection of the batteries and their cables.  In this photo you can see that Hilmi and Selim have installed these large T-class fuses directly to the Positive output of this 6S bank using a thick copper flat bar. 

The batteries are the very beginning of the circuit so these fuses are being used for Overcurrent Protection of each Red 120mm2 / 5/0 AWG cable.  If as is often done when wiring batteries, no fuse is used and the Red cable is connected direct to the Positive battery post then there would be NO protection of that cable as it makes it way from the battery to the Positive Bus Bar inside the Main DC Distribution Panel. 
With the potential of 24V @ 450Ah a short circuit on this positive battery cable would be VERY bad and a fire all but guaranteed.  Hence we use Overcurrent Protection on all our wires and cables. 

This adds a degree of expense and complexity but when Safety is involved all other factors take a back seat.


IMG_20200707_100821Back in the Workshop looking up at the ceiling right behind the end of the Engine Room Enclosure, we find another job that Hilmi and Selim completed this week by connecting the 24V power cables to the big Lewmar EVO65 winch up on the Aft Deck.  This winch will get quite a workout as it is how we lift the Tender off and on the Aft Deck and we’ll cover that more in the coming weeks as the Davit Arch gets built.

IMG_20200707_100805As you can see, the motor and gearbox assembly tuck up nicely in this space which will be even more protected with the AlucoBond ceiling panels are put in place.


IMG_20200709_181958On the Starboard/Right side opposite the Winch Hilmi has mounted this Junction box to house some of the connections of the wiring in the Workshop for some of the 24V consumers such as the Maretron Black Boxes and Workshop lights.

Every wire labelled at both ends of course.
IMG_20200709_181954Zooming out a bit to get the bigger picture you can see how this newest junction box sets nicely up in the boxed corners that wrap all the way around the perimeter of the Workshop and how well that beautify big overhead hatch brings in all the light and fresh air.  The large rectangular AL bracket will soon have the DC Distribution Panel mounted to it and all those large Red/Black/Yellow/Green cables will go in their to connect up to the Positive and Neg bus bars, circuit breakers and fuses.
IMG_20200707_111642Speaking of which, that DC Distribution Panel for the Workshop showed up this week so we now have all three of these Distribution Panels, two of which you’ve seen in previous weeks with one up in the Forepeak and the Main one down in the Basement.
IMG_20200707_111716All the cable glands have been pre-installed for all those cables you saw in the photo above and keeps each cable both securely mounted with a waterproof connection.  You will be seeing more of this panel as it gets mounted inside the Workshop and Hilmi starts connecting all the cables, wires, fuses and circuit breakers.
IMG_20200709_182005Panning to the Left to this area above the Fuel Manifolds, these are some of the Maretron BB’s and one of the bluish multi-port N2K blocks on the far Right where the N2K backbone connects with the larger Blue cables such as the one visible on the far Right.  The small white wires are coming from the various Maretron sensors for things like temperature, pressure, fuel flow, WIF Water in Fuel, etc..


IMG_20200710_134843Making a nice transition from electrical to aluminium “hotworks”, I finished up the design for this fairing block for the Aft Depth and Bottom Discriminating sounder and Uğur transformed it to solid 30mm thick aluminium in literally minutes.

The Black plastic transducer I’m holding is a Furuno 520-5PSD Bottom Discriminating Sounder which connects to a dedicated Furuno BBDS1 Black Box and then
BBDS screen shot 1sends the data and graphics like this out via Ethernet  cable to our boat computers and the TimeZero navigation software.  These sounders are most commonly used by commercial fishermen but having all this detailed information about the contours and materials below us is eXtremely valuable to us for checking out the best anchorage spots.
While very powerful, these BD transducers are very sensitive so they need to be well protected where they are exposed on the bottom of our hull from debris and possible groundings.  Strangely enough bubbles are the biggest “enemy” in terms of getting maximum performance from this and any depth transducer as they interrupt the pulsed sonar signals being sent and received by the transducer. 

IMG_20200710_151111This boat-like shape helps accomplish all these tasks; protects the transducer and smooths out the water flowing over the bottom surface of the transducer.

IMG_20200710_151105Equally critical is having the bottom surface of the transducer being parallel with the waterline so that the sonar signals are pointing straight down so we tacked the front end to the place on the hull we had strategically chosen and then used the laser level to get the bottom surface eXactly parallel with the “ground”.
IMG_20200710_151118Even though we had chosen a spot on the hull that was relatively flat there was still a good sized gap at the Aft end where the bottom plates start their sweeping curves up into the prop tunnel.
IMG_20200710_170514However it only took Uğur minutes to quickly cut some small triangular shapes of 5mm AL plate to fill that gap and then start laying down the first passes of weld to make this all integral to the hull.

Uğur will lay down at least one more bead of weld and then we will grind the block to an even more hydrodynamic shape and finish it up with epoxy fairing putty when we are prepping the bottom for the epoxy primer preceding application of the silicone base InterSleek 1100SR Foul Release bottom paint we are going to use.

IMG_20200710_170521One additional detail we designed in for an extra bit of safety with anything that is a penetration of the hull is that I had Uğur weld in a matching boat shaped piece of 5mm thick plate to the top of this 30mm thick boat shaped block before he tacked the whole block to the hull where it touches on the far Left/Forward end.  Click to enlarge this or any photo to see this 5mm plate and then the thicker 10mm hull plate above it.

Mr. Gee Mounting System

Gardner & Nogva mounts screen shotIn last week’s Update I outlined the design I came up with for mounting the Gardner and the Nogva to the beds in the Engine room using large anti-vibration mounting “feet”.  This week I finished up those design and construction drawings and Uğur got busy the brackets for Mr. Gee’s four “feet” and the two for his best buddy the Red Nogva CPP Servo Gearbox.

For the front Gardner mounts we need to extend or widen the inside of the Engine Beds a bit where the motor mount feet attach and for the Nogva feet we need to add an underhanging mounting bracket to the beds on both sides.

IMG_20200706_121354To help with your orientation in the real world, here is a shot standing up on the Aft Deck looking straight down into the Engine Room.  The two long parallel Mounting Beds you see in the rendering above are what you see here running from top to bottom in this photo.  Stern is at the top here so that is the Aft end of the Engine Room Enclosure at the top of this photo and out of sight at the bottom is the WT Bulkhead with the Guest Cabin on the other side.  Two large transverse Frames # 18 & 19 rare what you see spanning across between the two beds. 
IMG_20200706_124609Inside the ER looking Aft I’ve been busy laying out the exact locations for the mounts.  Getting the location of these engine and CPP mounts eXactly correct is eXtremely critical to the overall performance of the propulsion system so even though I’ve modeled every component very precisely in Fusion 360 3D modeler, I double, triple check all the numbers and geometry using independent hand sketches and pulling off real world measurements with tape measures, laser levels and machinist squares and then transferring this all to the aluminium with labels and lines on the masking tape I’ve put down along the beds.

The red flange halves up at the top are the zero reference or base plane that I have used for all my models and measurements as this 2 part flange is where the prop shaft connects to the output flange shaft of the Nogva CPP Gearbox.  When it comes time to align these mating flanges we have to get them to be less than 0.002”/0.05mm.  For reference a human hair is about 0.07mm in diameter so we don’t have much room for error when it comes time to align the Engine/Gearbox with the propeller flange.

IMG_20200707_101506Uğur has cut all the 25mm / 1” thick AL plates to size and prepped them for full penetration welds with the large 45 degree chamfers to form a deep V gulley for his MIG welding passes.
IMG_20200706_164722I really enjoy working so closely with Uğur and with all the modeling, measuring and marking done and all the plates cut and prepped time now for Uğur to start tacking them in place.

For orientation, the Door into the ER in the upper Left corner and the angled walls of the ER point to the Stern which is on the far Left.
IMG_20200706_181959The aft most mount for the Nogva Gearbox required this stringer be cut away where the mounting bracket plates will be and to provide enough room for the MIG gun to access.  New stringer plate will be welded back in again after the mounts are all done.
IMG_20200707_101546At the opposite front end, the supports for the bed extension required these slots be cut in the stringer under the 25mm thick Mounting Beds.
IMG_20200707_112605With all the interfering stringers cut away and slotted, Uğur could start tacking in the mounting plates starting with this vertical brace for the Stbd/Right Nogva Gearbox undermount and get it perfectly lined up with the reference lines I’ve marked on the bed surfaces.
IMG_20200707_122929He soon has both vertical braces tacked in place.
IMG_20200707_122936and then tacks in the horizontal base mounting plate.  My hand will give you a sense of size and scale.  Mr. Gee weighs in as a svelte 1400kg/3100lbs and the Nogva CPP adds about another 250kg/550lbs so these mounts need to stand up to several decades of support for over 17-1800kg / 3750-4000lbs of vibrating propulsion goodness so I am over engineering these beyond even my usual eXtremes. 

BTW, Mass is also a big help in reducing vibration and noise so there is that added benefit as well.

IMG_20200707_155825At the front end of the beds this Stbd/Right side bed extension is also now all tacked up and perfectly leveled ready for one last check with the laser level and straight edges before final welding begins.
IMG_20200707_155902Soon all four mounts, none needed for the two in the middle, are all tacked up, checked and ready for welding.
IMG_20200709_162002Front Bed eXtensions fully welded ready to be ground flat and flush.
IMG_20200709_182107As are the rear two undermounts with the stringer plates now added back in.
IMG_20200709_182553And here is a Birds-eye view looking down through the big ER Hatch on the Aft Deck.
IMG_20200709_174037Meanwhile, one floor up in the “Fitting Room” in my Workshop, I’ve been busy getting Mr. Gee’s new mounting brackets which we finished building last week, all fitted and installed on Mr. Gee himself as we prep for the big day of lowering him into his new home in the ER onboard Möbius.

These are the Aft two mounts that sit in the middle of the ER Beds.  The huge flywheel is also being prepped to mount to those six bolts on the end of the Crankshaft.

IMG_20200709_175325Seen from the front side and with the anti-vibration “feet” in place, this is what the finished Aft Mounts look like.
IMG_20200709_175339Front Right mounting bracket and foot test fit and good for final torqueing.
IMG_20200709_174104On the Front Left mounting bracket I have incorporated this extended base plate where I will soon be mounting the big Jabsco sea water impeller pump that provides all the cool seawater to flow through the heat exchangers for the engine coolant, engine oil and Nogva Gearbox oil before exiting out via the wet exhaust system and back into the seal. 
IMG_20200709_174112In the photo above, the PTO or Power Take Off drive can be seen on the far Left here and then viewed through the two holes in the vertical mount brackets.  I’ll be making up a SS drive shaft that will attach to that PTO end and go through those two holes in the mount and then be attached to the shaft of the Jabsco pump.  Should make for a very robust and reliable drive setup for this critical pump.


IMG_20200707_124453Mr. Gee’s feet were not the only thing I’ve been massaging this week, I also finally made the time to finish prepping the purposely “obese” flywheel option that Michael at Gardner Marine Diesel kindly provided for us.  This mass helps to further even out the legendary eXtreme smoothness of all low revving Gardner 6LXB engines and make Mr. Gee a real smooth operator to quote Sade Adu’s great song.
IMG_20200707_124456Many months ago I had sent this flywheel out to the CNC Machine shop next door to have that recess with the 8 M-12 threaded holes machined and now I needed to remove these no longer needed bolts and bearings that are used for mounting a traditional Gardner gearbox.
IMG_20200707_155939The outer circumference of the Flywheel also serves a critical function by having these precise marks that are used for setting the timing of the fuel injection pump.  There are three sets of these precision marks and this one is for setting the injection timing of #1 cylinder.  I have filled these stamped in marks with fluorescent Green paint to help make them easier to see through the timing window in the outer aluminium Flywheel bell housing.
IMG_20200709_155312I sanded these areas down to leave the Green paint just filling up the letters and masked them off before spraying on the primer and topcoats.
IMG_20200707_184950As always, all the time in painting comes from the prep work so after months of that it only took a few minutes to spray on the first coat of primer.
IMG_20200708_183520Followed the next day by the final topcoat of aluminium paint. 

A bit eXcessive for an item that will never see the light of day?  Perhaps, but with our last boat having been all steel and Neil Young’s refrain of “Rust never sleeps” echoing in my head, I try to do anything I can to prevent rust happening ANYWHERE on my beloved new boat Möbius!  Call me crazy if you like, you’d be in the majority, but I’m a very happy and rust free nutcase!

IMG_20200707_165905My anti-rust fetish had me take the time to sand blast the six anti-vibration feet so I could paint them while I had my spray gun out and the aluminium silicone paint mixed up,
IMG_20200707_184944And shot them at the same time I was shooting the Flywheel so they are now all ready for installation.
IMG_20200709_155320Final step was to insert this aluminium SAE14 Centamax 1600 drive plate into that recess I pointed out earlier and torque down the eight hardened M-12 bolts.
CentaMax 1600 rubber insertWhen it is time to connect the Gardner to the Nogva Gearbox, this rubber flex drive which is bolted to the input shaft of the Nogva, will slide snugly into all those matching U shaped grooves in the AL drive plate that is now bolted to Mr. Gee’s Flywheel.  This is one more very significant component helping to make Mr. Gee such an eXtremely smooooooooth operator.

This is Exhausting!

IMG_20200708_184928The last bit of TLC for Mr. Gee was getting these stainless steel flexible exhaust bellows machined and welded so we can start installing the Halyard exhaust system.  These SS woven mesh connectors work really well by absorbing any vibration or movement between the Gardner engine and the dry stack SS pipes running up and over the Gardner on their way to the Halyard Combi Silencer/Separator.

The round SS flange faces up and this is where the first vertical dry stack Halyard pipe attaches.
IMG_20200708_184950And the bottom square flange bolts to Mr. Gee’s exhaust manifold.  You will be seeing much more of this once we start installing the Halyard exhaust system later this month.

Why Drop Your Drawers When You Can SLlllllliiiiiiiiide Them Instead?

IMG_20200706_140238We kept dancing to Sade’s Smooth Operator song throughout the week and that certainly included all the work that Omur and Selim were doing in the Main Cabin and the Galley.

IMG_20200706_094259Omur continued installing all the beautiful Rosewood drawers in the Master Bed Platform with their super smooth operating Blum drawer slides.

IMG_20200706_125054As you may notice, our Chippies aka Cabinetmakers, went a bit overboard last year when they started building the first drawers for XPM78-01 Möbius and made EVERY surface out of Ro$ewood so my pocketbook and I needed to reign them in a bit and use the very nicely contrasting Beech for the insides and undersides and unseeable surfaces of all the rest of the drawers and drawers they subsequently made.

But as you are seeing here in the Master Cabin, all the drawers in the King Bed Platform are Rosewood throughout.
IMG_20200706_125130All the other drawers and doors in the Master Cabin and throughout the rest of the boat have this very lovely contrast of colour and grain between the dark swirling Rosewood and the honey coloured Beech.  Thee upper four drawers in this Bureau of Drawers beside the Master Bed Platform show this well. 

The upper four are slide out drawers whereas the bottom four where the hull curves in and makes them narrower have fold down doors.  The outer faces will soon receive their Gray/Green leather covered fronts.

IMG_20200706_125143I covered these AbFab Blum bottom mounted drawer slides ad nauseum last week so I’ll leave you to go check that out if you’d like and just point out that this is a good shot at the underside of one of the Bureau drawers to show how these slides and their cushioned auto-close mounts work.
IMG_20200706_140215and here is an interior shot of one of the sliders in one of the bed platform drawers.
IMG_20200706_164425Looking rearward to the stairs leading up to the SuperSalon, these are the six drawers along the Starboard/Right side of the Master Bed Platform.
IMG_20200707_114243And these are the five drawers on the forward facing end of the Bed Platform.
IMG_20200706_182249Last 2 drawers in the Master Cabin are the two Omur in front of Omur located underneath the Vanity Sink at the very front end of this Cabin. 
IMG_20200709_101019Omur soon has both drawers all mounted as well s the door on the Medicine Cabinet above the sink.
IMG_20200709_101103The Rosewood doors along that Starboard side open up into very large storage shelves with hanging lockers and the Washing Machine behind what will soon be mounted Green/Gray leather covered drawers above the BHL Handhold.
IMG_20200709_101124Difficult to fit it all into one photo but this shot standing in front of the Vanity sink provides this perspective looking down those doors on the far Left and along the Bureau of Drawers and the Bed Platform on your way to the hanging locker on the Left just before you start up the stairs to the SuperSalon.
IMG_20200710_182648Speaking of which this view looking straight down those stairs from the SuperSalon lets us see that Omur has also now installed all the solid Rosewood nosing on each of these stair treads.
IMG_20200707_123205The solid Rosewood nosing and intake air grills for each of the stair treads came back from the Finishing Shop with their multiple coats of PU varnish all rubbed out to a beautiful matt sheen.
IMG_20200708_101626Omur soon had these all fully installed and awaiting the installation of the final flooring which will be planks of click-lock high end vinyl.


IMG_20200710_130839Upstairs Omur and Selim continued to make good progress installing the Main Helm Station which we saw them begin the previous week.  The hinged Dashboard is now back from the Upholstery Shop along with the mounting panel for the two 19” touch screens and the cut-outs for the switch panels are in the angled wall on the Right side of the Helm Chair.
IMG_20200708_132504I was finally able to get a photo of Sinan our Mater Upholsterer standing beside the latest round of ceiling panels for Möbius as well as the three Black Leather covered Dashboard pieces.
IMG_20200710_182735This is the basic layout that Captain Christine has come up with and is now in place.  Kobelt Throttle/Pitch control levers bottom Right, Furuno Jog Lever to its Left and then the Gray cover is hiding the Furuno 711C AutoPilot Head.

Above the Jog Lever is the Maxwell Windlass Chain Up/Down switch with the round Kobelt Pitch Angle gauge to its Right and the ACR Pan/Tilt Searchlight control in the Upper Right corner.  The empty hole beside is waiting to be filled by the Vetus Bow Thruster Joystick that has not yet arrived.

IMG_20200710_182757The hole on the far Left corner will have a smooth radius ring on it and will allow the Standard Horizon RAM4 VHF mic cord to coil up in the space below.

Vertically mounted on the Right wall is the Nogva Clutch & PTO control switches and the empty rectangular cut-outs will soon have the switch board mounted to control all the exterior flood/search lights and the High Water Bilge controls system.
Kobelt 7176 Walk About RemoteUp on top of the Right side angled wall, that Black Kobelt panel is the Kobelt control station to give control to either the Main or the Flybridge Helms OR give control to this Kobelt 7176 WalkAbout Controller which we are eXtremely eXcited to try out soon.  This is a corded remote control which can plug into a receptacle here at the Main Helm or up in the SkyBridge Helm and the 10m/33ft cord then allows us to “walk about” almost from stem to stern with this remote.  It is eXtremely multi-functional as the two levers on the sides control the Pitch of the prop and Throttle of the Gardner and then up on top we can control the rudder, the bow thruster and the CPP Clutch.  With this in hand we can pretty much control the whole boat while standing anywhere on the boat from the very aft end of the Swim Platform to up on the Bow.
MVIMG_20200710_182952In addition to giving you an overview of the whole front end of the SuperSalon and the Main Helm, all those wires hanging down from the ceiling indicate that Hilmi and Selim have been here putting in all the power cables for the LED lights overhead.
IMG_20200710_182741Most of all though, Christine and I are already fantasizing about sitting in our super comfy Llebroc Helm Chair up here and gazing out through these 360 degrees of windows as we head out towards our next great destination. 

Come on Team Möbius, we are counting on you to get us there ASAP!

SuperSalon gets Superer!

IMG_20200708_133223It is a hard area to photograph well but the “doghouse” overtop of the Entryway from the Aft Deck into the SuperSalon is shaping up very nicely thanks to Ömür’s hard work.

This shot is looking straight up while standing on the Entryway Stairs.  Omur now has the very nicely done Rosewood Hatch liner installed and Sinan has finished the first of the intricate snap in White leather covered ceiling panels on the Right here.  More to follow soon.

IMG_20200708_133238Here is a different perspective on that same area looking in through the Entryway door on the Aft Deck.  The Black Corner Box running across the upper ceiling area will have a snap In/Out panel to give us access to the various electronic gadgets that will live inside.

The SkyBridge is on the other side of the far right side here and …….
IMG_20200708_133251…… if I now climb up to the SkyBridge you can see this same Hatch liner from up here and get better oriented.
IMG_20200708_133259Walking a few steps forward in the SkyBridge and looking back at this same Hatch you can see where the SkyBridge Helm Chair will set in that space to the Left of the Hatch.  We have oriented this Hatch lid like this to make it easy for us to pass things back and forth from the Galley and the SkyBridge and to make it easy for us to talk back and forth when we are in these two areas.


IMG_20200708_132310Can you guess where these three little drawers are bound for?
IMG_20200710_093451Well, I guess the heading of this section makes that easy to guess that they go HERE on the “peninsula” in the Galley that runs parallel with the walkway as you come down the stairs from the Entryway door.

One of the main themes Christine and I prioritized as we worked through the design of XPM78-01 Möbius is what we refer to as “Diversity” by which we mean having a lot of different options for different aspects and areas onboard.  in the case of the Galley that means a lot of diversity of size and shapes of drawers and doors so have a look around and see how this design diversity is manifesting itself in the Galley.

BTW, the tall skinny area in the middle of this set of different sized drawers will also be a pull out “drawer” that has no sides and just a series of shelves to store things like spices and condiments and utensils that you can easily access from the side.

IMG_20200710_093502Drawer Diversity continues over here on this set of drawers on the Window side of the Galley countertops forward of the double sink.
IMG_20200710_093508And yet more different sizes and shapes of drawers here on the other “peninsula” running along the back of the Dining Settee on the other side.
IMG_20200709_101254A bit difficult to see through all the construction but you can see how all the Garages atop the Turquoise marble countertops are also different sizes and depths for yet more diversity of our storage.  Our hope is that having all these different options will allow us to optimize all these storage areas and enable us to find the Goldilocks just right spot for everything we want to store in our Galley.
IMG_20200708_183744Also eXciting for us to see the big double sink be permanently set into the marble countertop.  And yes we heard all your questions and recommendations for a undermounted sink instead and we may well agree with you for the next boat, but we are very happy with this top mount and thing it will work well for us.

IMG_20200709_100759The large main faucet has a removable spray head with a very effective magnetic holder to keep it in place when not being used.  The smaller faucet on the far Right is just for cold drinking water which comes from its own 150 Liter tank that is completely independent of all other water tanks for an extra bit of safety should it ever happen that all six of our integral water tanks should be somehow contaminated. 
Highly unlikely as they are all filled from our 150L / 40 USG per hour Delfin Watermaker, but just in case ………………

Whew!  Even when shorthanded the rest of Team Möbius still makes great progress and we get closer and closer to Launch Date!

Oh, and one last bit or eXciting news, look what we just received!

Certificate of British Registry in Jersey for Möbius address blurred outHoly Pinocchio!

It is NOT a Fake News lie that XPM78-01 Möbius is now a “real boy” as she is fully and officially registered in Jersey and the British Ship Registry! 

I realise that this might seem like “just a piece of paper” to many but to us this is such a big milestone that makes our dreamboat seem all the more real and tantalizingly close.

Thanks as always for joining us on this grand adventure and PLEASE add your questions, comments and suggestions in the “Join the Discussion” box below.

Till next week, same time, same Bat station this is your cub reporter Wayne and Christine’s Loving Owners Representative signing off.


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

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.
