Let the Chips Fly!!  XPM78-01 Möbius Progress Update Dec. 9-14, 2019

Let the Chips Fly!! XPM78-01 Möbius Progress Update Dec. 9-14, 2019

Another busy week here at Naval Yachts for all of Team Möbius as we ramp up for the final push to launch as early in the new year as possible.  It remains a labour of love for Christine and I but it certainly is all consuming of our time and attention.  This week saw progress in everything from CNC machining the new Tiller Arm now that the Rudder is pretty much finished and ready for installing in the hull to finishing the installation of the prop shaft tube into the hull, plumbing for the in-floor heating system, wiring and of course lots of cabinetry work.  It will take me awhile to get through it all for you so grab a beverage and a comfy seat and let’s go aboard Möbius and check it all out.

TILLER ARM

 IMG_20191209_133245Most of our work with Aluminium to date has been with large plates which are CNC cut to shape and pieced together to form the hull and superstructure.  However as you can see in this photo this hunk of aluminium beauty ain’t no plate! 


IMG_20191209_134155If I tell you that this 152 x 255 x 275mm (6” x 10” x 11”) and 30kg/66lbs block of solid aluminium is just one half of the part, can you guess what this is going to be?


That 150mm/6” long 25.4mm/1” precision ground threaded pin is specially hardened steel to easily withstand the eXtreme forces which can be exerted on it where the Heim Joint ends of the cylinders attach to the Tiller Arm body.  I ordered these and 2 spares from McMaster Carr and brought back with me from our recent trip to Florida.


Tiller Arm bodyA bit of a no brainer given the title of this section I guess!!  A Tiller Arm.

These two quick screen grabs show the design I came up with using Autodesk Fusion 360 which I must say is my all time favorite design and drawing software of all time and in my case that is a LONG time!


You can see how the right side is the second half I mentioned and those four large bolts clamp the Tiller Arm to the 127mm/5” Rudder Post with the 20mm key that goes in the slot on the left side main body.

Tiller Arm w cylinders Turning on some hidden components you can see how the two Kobelt 7080 bi directional hydraulic cylinders with a bore of 76mm/3” ID and stroke of 305mm/12” provide plenty of torque as they push/pull the Tiller Arm which in turn rotates our big rudder up to 45 degrees to each side.


eXcessively massive, time consuming and expensive?  Of course, this is an XPM! and the steering system is arguably the most important system on a passage maker so I’m delighted with such eXcess.


Each cylinder is connected to its own dedicated Kobelt/Accu-Steer HPU400 Hydraulic Power Unit.  Dennis and I worked extensively with the great engineers at Kobelt to come up with this eXtremely robust steering system.  We have designed it such that just one cylinder and one pump significantly exceed the steering requirements to safely steer the boat in even the most severe conditions. 


There will be controls at each Helm station to allow us to select either Steering A or Steering B and our SOP Standard Operating Procedures will be to alternate using A and B for a week or so to ensure both systems are fully operable and being used equally.  At any time for situations such as close quarter maneuvering we can have both pumps and both cylinders working at the same time which cuts our lock to lock rudder time in half.

In the unlikely event that both pumps and cylinders were to fail we then have a Kobelt 7005 manual hydraulic steering pump with wheel at the Main Helm.  And if all of that were to somehow fail we then have an emergency tiller which can manually control the rudder.

tasot_buildingBack to real time photos, the CNC machining is all happening in a building 2 blocks over from Naval Yachts here in the Antalya Free Zone at Tasot Waterjet Cutting Technology
IMG_20191211_154521_MPThey have a small warehouse filled with some of the most advanced metal cutting machines of every description and having the literally next door is one of the great advantages of building here in the Free Zone.

IMG_20191209_133729Here is the whole gang responsible for transforming my design into a very real aluminium Tiller Arm.  From right to left, Yigit our XPM Project Manager,  Hamdi Uysal CNC machinist, Ufuk Bekci Tasot Owner and Tuncay Mutlu Production Engineer

IMG_20191211_153809IMG_20191211_153803One half done, now on to the Tiller Arm Body.
IMG_20191213_111224With one side of the main Tiller Arm body finished, roughing out the second side begins.  Easy to see why this is called “subtractive manufacturing”.  3D printing is the opposite “additive manufacturing”.
Here is a short little video I’ve put together to show you what this looks like in action.

I was too busy on Friday to get back to see the finished Tiller Arm body so I’ll show you that in next week’s update.


IMG_20191120_121849Meanwhile back at Naval Yachts, the Rudder is all finished and patiently waiting to be installed as Nihat and Uğur ae busy getting the 10mm thick walled 200mm ID Rudder Tube tacked in place as they prepare to insert the finished Rudder. 
Rudder Prop ghosted viewChoosing a few relevant layers in the 3D model and using “ghost” mode this quick render will help you see how the various pars such as Rudder, Prop, steering cylinders and Tiller Arm fit together.  This is in the aft end of the Workshop with the door out to the Swim Platform in the upper left.

.

IMG_20191210_142908In reality mode here is the Rudder Post Tube now tacked in place and just sticking up above the Rudder Shelf.  Same Workshop to Swim Platform door on the upper left.  Next week when the Rudder Post Tube is fully welded in place you’ll see the Rudder post sticking up through this tube with the Jefa self aligning needle bearings top and bottom and the Tiller Arm on top.
IMG_20191210_142945Looking underneath the Rudder Shelf reveals the 25mm/1” thick AL brackets which tie the Rudder Post Tube to the stringers, frames and prop tunnel of the hull and make this all one integral hull assembly.
IMG_20191210_142926Limber Holes or ”Mouse Holes” in the corners where these tube braces will be welded to the hull plates ensures that any water which finds its way in here can easily flow to the lowest point and be removed by the bilge pump and not trapped in these compartments.

PROP SHAFT & LOG MOUNTING

IMG_20191210_102551You may recall from an update a few weeks ago that the machined Aluminium tube, the one with the holes in it here, which the Nogva CPP prop shaft runs inside of, had been fitted into the larger aluminium prop tube that is part of the hull which you can see running up to the top left corner here.

See something new though?

What’s that Orange stuff in that little stubby bit of pipe?
IMG_20191209_173634_MPAnd what might this bit of kit be that is on the floor just below the prop shaft tubes?
IMG_20191209_173935And what are they mixing up here?
IMG_20191209_173919Some of you will recognize this quite universally used Chockfast Orange which is a special 2 part compound which is pumped in fill voids between two parts and rather permanently fasten them together once it hardens.
IMG_20191209_173853After being thoroughly mixed with the hardener the syrupy Chockfast Orange is poured into the red tank you see in the photos above, the lid is bolted down and the tank is filled with compressed air.


IMG_20191209_173910Then a tube connects the bottom of the tank to the filler tube which is temporarily welded to the hole in the top of the hull’s prop shaft tube and the Chockfast flows into the 12mm/ 1/2’” space between the outside of the Nogva Prop Log tube and the larger inside diameter of the Hull’s larger welded in prop tube.
IMG_20191209_174036Up inside the Engine Room, the other end of the prop tubes which have been precisely locked into position with this clamping jig and a tube has been inserted into the pipe that has been temporarily installed where the two tubes have been sealed off to stop the Chockfast from leaking out.
IMG_20191209_174045A few minutes later the Chockfast has filled the entire void between the two tubes and exits out the tube.  Several cupful’s are collected to make sure any entrapped air escapes and then the valve on the Chockfast tank is turned off and we leave this to fully cure in the next 48 hours.  Once fully hardened the two tubes become essentially a single part and provides plenty of space for water to surround the spinning prop shaft at its center. 
IMG_20191213_171521With the Chockfast fully hardened the prop shaft was fitted again to double check the position of this red flange which will soon be bolted to the output flange of the Nogva CPP gearbox.

Where the prop shaft exits the prop log tube there will be a “dripless” seal that fits over the end of the prop tube and seals against the spinning prop shaft to keep all water where it belongs; in the sea and outside the boat! 
IMG_20191213_171525A close up view of the threaded push/pull Pitch rod which runs inside of the prop shaft.  This rod threads into the Nogva gear box and is moved fore and aft by the Pitch Control lever at each Helm.  As the rod moves fore/aft the four prop blades rotate in synch and changes the pitch to anything from neutral, forward or reverse and as more pitch is added the speed of the boat increases.  All a very simple and mechanical system which gives us the ultimate prop, one that is perfectly pitched for any condition.
IMG_20191210_102551At the propeller end of the prop tube, water exits out these holes drilled around the circumference of the machined end of the Nogva prop tube.

Next week the Cutlass Bearing which supports this aft end of the prop shaft will be press fit into place and the CPP prop and shaft assembly can be carefully slid in place for checking of the final fit as we prep for installing the Nogva CPP Servo gearbox.
ELECTRICK GRILL
IMG_20191212_161620One of the many items in that big crate you saw arriving from Florida last week was our Kenyan “Frontier” 220V electric grill that is part of our Outdoor Galley on the Aft Deck.  We no sooner took the box out of the crate than Nihat and Uğur whisked it away and cut in the opening for the grill in the Starboard/Right Vent Box.
IMG_20191212_161620Deciding to go all electric for this BBQ was part of our ability too make Möbius be a single fuel, all diesel boat.  The other big part of this was going with an internal diesel engine in our Tender and I’ll have more for you on all of that in the coming weeks.


All the top surfaces of these two Vent Boxes on the Aft Deck will be countertops, probably using some of the left over turquoise granite from the Galley countertops.  There will be a SS sink in the open space you see here in front of the grill.


IMG_20191212_104050Speaking of electrical, I only managed to catch a few shots of Hilmi and Okan’s progress with some of the wiring this week.  Okan was busy in the Basement prepping these cable trays to be mounted on the ceiling which will be used to support those huge 120 mm2 / 5/0000 AWG red and black cables.

PLUMBING

IMG_20191211_124838Cihan was also a busy boy this past week installing plumbing pieces for several different systems.

He has masterfully crafted these two manifolds for some of the Cold and Hot water systems for moving water from one of the six tanks to another as needed to adjust ballast as fuel is removed and others for getting water from the watermaker you saw last week, to each of these tanks.
IMG_20191211_124851He has done a beautiful job of insulating all of these to increase efficiency of the DHW Domestic Hot Water lines and also keep the Cold water lines from absorbing ambient heat in the Workshop when we are in hotter tropical climates.
IMG_20191213_122907Moving forward to the Basement, more of Cihan’s fine work this week was getting the dedicated Galley Water tank in place.  This is probably more “eXcess” as we can hold as much as 7100L/1875USG of potable fresh water in our six integral tanks in the hull and we have the 190L/hr / 50USG/hr Delfin watermaker.
However as you’ve read previously and often, we always design with our “Readiness for the Unexpected” in mind and this additional 200L/55 USG polypropylene Potable Water tank is one example.  We will treat this similar to the Day Tank for our diesel fuel by keeping it full at all times and it will be plumbed to an independent faucet at the Galley sink.

IMG_20191213_122942Wonder what that shiny item sitting atop the Water tank is?  Yet another bit of kit out of that crate from Florida, this is the manifolds for the three in-floor heating zones.  To my eyes it is a beautiful work of art in its own right and is almost a shame it is down in the Basement where not too many eyes will see it.  The top 3 red towers are flow meters which you adjust with the white knobs on the bottom.
IMG_20191213_171857After some discussion, Yigit, Cihan and I decided this would be the best location for these manifolds, secure against the WT Bulkhead with the Guest Cabin on the other side. 
Supply of hot water enters on the top right and goes out to each of the 3 in-floor zones from the bottom of the Red upper manifold and then returns through the three fittings under the White knobs and back to the Domestic Hot Water system on the bottom right.  Ball valves on all lines coming in and out and temperature gauges on both supply and return so I can monitor the difference.


IMG_20191213_123033Each zone has one of these 3 speed 1/25HP pumps on the supply side to keep the water circulating through the 15mm PEX lines embedded in the floors.
IMG_20191213_123002In the foreground on the left is a Watts mixing valve plumbed into the floor heating water system to help manage the lower temperature water needed for in-floor heating which wants to run between 30-500C/85-1200 F.

In the background is the Azel I-Link three zone Pump Controller which is controlled by individual temperature sensors embedded in each cabin floor.

I’ll have more to show you as Cihan progresses with the installation.

CABINETRY WORK:

IMG_20191209_121805_MPMy Beautiful Bride, aka Captain Christine is at the shipyard most days now and here she is going over the details for the cabinetry and fixtures in this Guest Cabin Head/Bathroom. 
IMG_20191210_172835Standing in the Guest Shower for this shot you can see that Omer has been practicing his cabinetmaking craft very well in this Head.  With the Guest Cabin serving as her Office the majority of the time and with this Head being so close to the SuperSalon entrance and the aft Workshop, it will likely get more use than the Head in our Master Cabin so worth making sure it has the Goldilocks touch of being “just right, just for us”.
IMG_20191211_103715Christine spent a LOT of time searching for this just right sink and finally found one and had it shipped to me in Cannes when I was helping out Naval at the boat show there back in October and I brought it back on the plane with me.

Raised platform in the back is where the VacuFlush toilet will rest at the Goldilocks height.
IMG_20191211_174158Up in the SuperSalon Omur and Selim continue to make great progress.  Here Omur is putting in the perimeter framing for the rigid foam insulation on each stair tread leading down into our Master Cabin.
IMG_20191211_174152All the floors have 40mm/1.6” thick rigid foam board which the 15mm PEX tubing is embedded into and then some of that light weight poplar 10mm marine plywood covers that and the edges of the plywood attach to these epoxy coated solid wood frames.
IMG_20191213_110030Opposite the stairs where Omur and Selim are working you can see how this white framing also provides the perfectly level foundation for all the cabinetry to mount to.
IMG_20191213_171747By week’s end the wall boards were being fitted and will give you, and us, a better sense of how this room will look. 


The large opening on the far right is for a 50” high def monitor which will serve double duty as both our primary entertainment screen for displaying movies, photos, web browsing, etc.  However it is also on a 3 axis mount which enables us to pull it out and rotate it forward where it is perfectly aligned for viewing charts and boat data from the Main Helm chair when underway.

The large vertical openings on the far left will soon house two Vitrifrigo 130L/35USG fridges with doors opening from the center.  The center cabinet is for two of Vitrifrigo’ s band new DRW70  70L/19 USG slide out drawer freezers which can double as fridges with a simple change of their thermostats.

IMG_20191213_110344Over in the Cabinetry Shop I happened to catch Omer as he was gluing up one of the Galley drawers and shot this sequence of shots for those of you who have been asking how the wood “biscuits” I’ve been mentioning work to align and strengthen the glued up wood joints.

You can see 2 biscuits with freshly applied glue on the right….
IMG_20191213_110413One of the drawer sides which has a matching grove for the biscuit is slid in place.
IMG_20191213_110553Same thing for the opposite side.
IMG_20191213_110713Two biscuits and some glue for the final drawer side.
IMG_20191213_110720_MPThanks to the ingenious biscuit power tool which cuts all these grooves everything lines up just right.  The biscuits are made from highly compressed wood fibres so as they soak up the glue they expand and make the joint even tighter and stronger.
IMG_20191213_110317Rinse and Repeat the process and this collection of glued up drawer carcases starts to form.  Once the glue dries plywood drawer bottoms slide into place and are glued and screwed in position to create very stable drawers which slide in and out on their ball bearing self closing slides with just a touch.

POWER!!


IMG_20191209_105220Remember that crate we build and filled with all sorts of parts and equipment that we were sourcing out of the US and arrived last Friday?  Uğur helped me open it up and unpack it all this week.
IMG_20191209_105352Literally hundreds of items inside from Milwaukee cordless tools for me to premium Belgium made pots and pans for Christine and then LOTS of parts for Möbius and they all made it on their flights from Miami to Antalya just fine.
IMG_20191209_115452Two of Möbius’ items whose arrival  we are most excited about are these two bright red beauties from Electrodyne.  I have been working closely with the fabulous people at Electrodyne Inc. for well over a year to have them build these eXtremely heavy duty 250A 24V alternators for us which combined will put out almost 14kW.  So when I say that we don’t have a generator onboard I guess that’s not entirely true?!

** WARNING:  mini Tech Talk Ahead!  Skip over if not interested

I’d known Electrodyne alternators since I was working as a HD construction mechanic in my youth and Electrodyne alternators were the ultimate choice for large construction and mining diggers, railroads, trucks, busses, emergency vehicles where they often ran 24/7 for weeks or months.  They are literally built like tanks and each one weighs 40kg/90 lbs! 

I’d initially worked with Pete Zinck until he retired early this year and turned things over to his Production Manager Dale Gould and who could not have been more helpful and responsive to my many Emails and requests.

What you are seeing in the photo above are two identical Electrodyne G250-24 models which are de-rated down to 250Amps @ 27.5V @ 3750RPM which would give each one a maximum output of almost 7kW (6.875) for a combined output of almost 14kW.  However I will make the serpentine pulley ratios such that their max speed will be about 3200-3400 RPM for even longer life.  Dale stripped these down for safer, and slightly lighter shipping and I have not had time to mount the HD steel wiring boxes which house all the wire connections you see here for the six large external direct AC output cables which then run over to the external rectifiers and regulators which I will mount outside the Engine Room with thermostatically controlled fans to ensure they are always running nice and cool and at maximum efficiency.  I’ll cover all that in the coming weeks as I get these alternators installed on Mr. Gee our Gardner 6LXB and wired into the electrical system.

I had a list of key features I wanted for our dual XPM alternators running off our single main engine and I knew that it was going to be a challenge to find a company that would build these so with my long past experiences with their alternators I turned to Electrodyne and sure enough they were able to built in all the features I wanted,   In addition to being rock solid, high output and lasting “forever”, perhaps the most significant features that I wanted were that they be brushless and I wanted them to have everything other than the rotating stator to be external.  No built in regulators and no rectifiers.  Why go to such extremes?   In a work; HEAT, which is the largest factor in shortening an alternators output and lifespan. Rectifiers can produce more than half the total heat within an alternator so by removing these and going with industrial grade 3 phase bridge rectifiers I can reduce the internal head of the alternator by more than half AND control the heat of the rectifier bridges outside the ER and with their own fans.   This also creates an alternator with only one moving part, the spinning rotor so MUCH better airflow through the alternator stator windings and rotor.  The Goldilocks alternator for an XPM; consistent high output with low heat and low maintenance. 

I will cover these Electrodyne beauties in much more detail in future posts here once I get them all assembled and installed but suffice it to say that I am VERY excited about getting these Electrodyne alternators installed and tested.  Equally as exciting are the WakeSpeed 500 Advanced Regulators that were also in this same crate of equipment we unpacked this week and will be controlling and managing our two mighty Electrodyne alternators. 

If this stuff interests you as much as it does me then please stay tuned and be sure to subscribe to the blog so you don’t miss any of the new articles as they go live.

OK, now back to our regular programming.

Mr. Gee Gets Naked!

Captain Christine is now working at the Naval Shipyard with me most days now as we make the final push to finish this build and bet Möbius and ourselves back were we belong; ON THE WATER!!

IMG_20191207_141759_MPAmongst her many jobs Christine has literally rolled up her sleeves, donned her HD latex gloves and become Mr. Gee’s personal degreaser!  Our Gardner 6LXB serial # is 196071 which means he emerged out of the Gardner and Sons building in Patricroft in Manchester England in February 1975 and was in constant use powering a tugboat in the Thames river everyday thereafter. 
After 45 years of such use we are giving Mr. Gee a serious bath to start his second life as our main engine in Möbius.  To do so we have removed every single part, nut, bolt and cotter pin and have now removed pretty much every bit of grease and guck that has accumulated over his glorious 45 year past.


IMG_20191207_163006With all the other duties I’ve unexpectedly taken on here along with the regular demands of building a new boat I’ve not been able to get as much time as I had expected to attend to Mr. Gee’s needs but I am contributing more of late and managed to get this massive chrome molly (chromium molybdenum steel) crankshaft all cleaned up and returned to its original shiny self.
20132710_10155688267755572_903598832_oThis is Michael Harrison, the CEO of Gardner Marine Diesel Engines who continues to keep the Gardner name alive and very well.  Michael was also the one who found Mr. Gee for us after a very long search for this completely original unrestored marine version 6LXB.


The Gardner 6LXB, and most Gardner engines for that matter are built with four primary building blocks:

  • Cast Aluminium Oil Pan
  • Cast aluminium Crankcase
  • Cast Iron Cylinder Block with pressed in dry liners
  • Dual cast iron heads

IMG_20191212_110343After one of several strip downs, I had reassembled all these major castings and had the exterior thoroughly sandblasted and then put on several coats of high temp silicone based primer. 

Now stripped down naked once again and ready for the bath of his lifetime, Hakan helped me drag the bare cast aluminium crankcase outside.
IMG_20191211_150746Armed with some super HD degreaser, lots of wire brushes and our newly acquired Bosch pressure washer, it was bath time!
IMG_20191212_110927I had spent the previous 3 days scrubbing every nook and cranny with the degreaser and wire brushes so this final pressure wash took us back down to virgin raw aluminium throughout.  I also wanted to be sure to blast out every oil gallery and hole to remove not only the old grease and grime but also any new particles that had climbed aboard during the sandblasting.
IMG_20191212_125617And here is the result, a VERY clean Mr. Gee!
IMG_20191212_125629This is the front end of the crankcase which will soon be filed with lots of sprockets and an eXtremely large double roller timing chain that drives everything from the camshaft to the PTO for one of those Electrodyne alternators to the water pump and fuel pump.
Whew!!  It is now late on Sunday night and I’m exhausted and so are you probably if you’ve made it this far! 

Thanks so much for joining us, makes this adventure all the more exciting and rewarding to know you’re out there and along for the ride.

Do please add your comments, questions and suggestions in the “Join the Discussion” box below.  Even though I am WOEFULLY behind in responding to those of you who have done so in the past 3 weeks.  Rest assured I DO read them all and think about all you say and I will respond to each one in the next few days so thanks for your patience.

Cables, Crates & Counters XPM78-01 Möbius Progress Update Dec. 1-6, 2019

Cables, Crates & Counters XPM78-01 Möbius Progress Update Dec. 1-6, 2019

Wow!  Surely my calendar is fooling me; December already?  Another year winding down to a close?  Where does the time go??!?   I’ve long been fascinated by the dichotomy of how our sense of time past works where the same amount of time can seem to simultaneously much longer and much shorter.  In the case of Möbius it seems like both yesterday and a lifetime ago when we first started this crazy idea of switching from sail to power for our future voyaging.  Then we dove head first into the deep end of the crazy pool by deciding to design and build it from scratch and started this wild adventure we are now on. 

Here are just a few examples of the kind of mental dichotomy that fascinates me; Last month we passed our two year anniversary of being here in Antalya, 612 days ago (April 6, 2018) the first shipment of aluminium CNC cut plate arrived and construction of the hull began and in a few days (Dec. 19, 2018) it will have been one year since we signed on with with Naval Yachts to build the fully finished boat with them and have it be the first “prototype” of their new line of  eXtreme eXploration Passage Maker XPM boats.  How is it possible that SO much has happened in SO little time? 

Well, not to waste any more time, I will ponder and wonder that question for a long time to come but for now let’s get on with catching up on all the progress Team Möbius has made this past week of December 2-6, 2019.

WIRING

IMG_20191129_124242Let’s start this week’s update with the electrical wiring.  The cables referenced in this week’s title include these four black and red eXtreme beauties which carry the eXtremely high amp 24 volt current from the 1350A @24V house battery bank to the fore and aft DC distribution panels. 
IMG_20191202_120822As per their labeling, each of these cables is 120 mm2 which would equate to about half way between the American Wire Gauge or AWG of about 4.5/0000.
IMG_20191129_123825By any measure these are huge and we are doubling these, two positive and two negative so that each pair carries half the amps. 
IMG_20191129_103948Why such eXtreme sizes?  In short, Electrical efficiency such that we keep the voltage loss occurring on these long cable runs as low as possible, meaning that as much of the current that leaves the batteries arrives at the consumers on the other end.  Our standard maximum voltage drop for all DC circuits is < 3% and for the main supply cables such as these, we keep it under 2% and hence the large cable size.
IMG_20191202_164648Last week Hilmi ran the four cables from the Basement up to the Forepeak using the cable trays you see in the photos above and this week he ran the other set of cables up from the basement and along the cable trays under the side deck space flanking the SuperSalon you are seeing here and running back to the Aft DC Distribution Panel in the Workshop.
IMG_20191205_122401Down in the Basement where the House Battery Banks are located we find this growing collection of different cables which now includes the four 120 mm2 Red/Black cables. 
We had ordered the negative cable in Yellow which is the preferred new ABYC standard to help differentiate the DC negative from Black AC wires but this large size cable is difficult to find and the Yellow jacketed version wasn’t available for several months so we went with Black and will add extra labels along each cable run to maintain clarity.  Not that anyone would likely confuse these huge cables for anything but high amp DC, but you can never be too careful when it comes to all things electric.


IMG_20191206_132153The two House Battery Bank bays which as you can see here are integral parts of the framing of the hull straddling the 25mm / 1” thick Keel Bar which is what the floors of these two bays are setting upon.
IMG_20191206_132157Nihat has been welding in the side framing which will hold the composite containment boxes in place and bolting these floors to the hull.  Even though all our batteries are fully sealed AGM type batteries with no actual fluid in them, we are building composite containment boxes to add an eXtra layer of safety to cover any possibility of a leak in one of the batteries. 
The L-bar frames hold the base of the batteries in place and then there will be a separate frame that wraps around the tops of the batteries and clamps them down to the hull so they can not move even in the unlikely event of a full 360 degree roll.

ALUMINIUM WORK

IMG_20191203_105804_MPUğur and Nihat continued their work on fabricating the framing for the glass and acrylic windows up in the SkyBridge. 
IMG_20191202_171625They have all the L-bar tacked in place that will provide the frames for gluing in the lower glass “eyebrow” windows and then started to weld in the flat bar on top to create the window ledges for the upper removable acrylic sheet windows.


Note the large vent seen in the foreground here.  This will have a large mist elimination grill in front of it before all the fresh breezes flow down into overhead diffusers in the SuperSalon. 


IMG_20191202_171642The front three 380W solar panels attach to a frame which sets just inside the upper angled edge of the space in front of this vent opening and hinges along the upper edge of the vent frame. 
IMG_20191202_120407This hinged frame of solar panels allows us to lower its front edge down onto the aluminium roof panel and seal off this space when we are on passages and then unclip it and raise it to its horizontal position which creates a huge wind tunnel to capture all the breezes coming from the bow when we are at anchor and funnel them all to this big vent and down into the SuperSalon.
IMG_20191203_104233The flat bar window sills were slot welded to the tops of the L-Bar glass window frames and then ground flush and invisible.  The angled support you see on the far right here is the articulated support post that is put in place when the roof needs to be folded down into either Cyclone or Canal mode.  Most of the time it is removed and stored in Workshop.
IMG_20191202_120330The front four support posts for the roof are attached with these bolt on flanges so they can be removed prior to folding down the roof.
IMG_20191202_120322Same bolt on flanges are mounted vertically where these four posts attach to the the roof frame.

CABINETRY WORK

Both of the Cabinetry teams continued to make great progress on their respective cabinetry work for the Galley and the Guest Cabin areas so let’s go check in with them.

PANO_20191206_131844.vrThe spacious SuperSalon is difficult to capture well with photos but perhaps these two panorama shots will help.  This one shot standing in very front where the Helm Chair will be looking Aft.

Click to enlarge any photo.
PANO_20191206_132007.vrShot standing on the stairs up to the Aft Deck looking forward.  Obviously very distorted views but when combined with the regular photos I hope it helps you visualise this truly Super space.
IMG_20191205_103007_MPSwitching back to normal photo mode AND sparing no expense we have brought Chef Christine aboard to inspect her rapidly evolving Galley.
IMG_20191205_103301Testing out a simulated pot stirring position where the induction cook top will soon be installed, the Chef seems to approve.
IMG_20191203_140449Omur and Selim spent much of the week painstakingly fitting the Gull Wing door Garages into the Galley cabinets.
IMG_20191203_150326With mitred corners and being recessed into the countertops requires very exacting dimensions along all three X,Y and Z axis in order for it all to work and for these Garages to be able to slide into their final position.
IMG_20191204_182738And when they do, it looks abfab!

For those wondering, the Garages are “floating” above the countertops to allow for the 20mm/ 3/4” thick granite countertops.
IMG_20191206_160607_MPeXacting is what Naval’s Cabinetmakers eXcel at and here is another example as Omur (left) and Selim try out different sheets from the flitches of Rosewood we’ve purchased. 
IMG_20191206_160553_MPWhen the thin sheets are sliced off the solid slab of Rosewood they are laid together in in the sequence as they come off so each sheet is different but matched with the one before and after. 
IMG_20191206_160546Omur has brought a series of these sheets onboard and is now trying out each one to find the Goldilocks match with the sheet on the right which forms the back of the dining settee.
IMG_20191206_131725Selim and Omur also fitted the armrest end of the dining Settee.
IMG_20191206_131753_MPThe top will be padded and upholstered and there will be a  door in the Rosewood outer side to provide access to one of the electrical panels that will be housed inside.

LOTS of storage space below and behind the seats as you can see.
IMG_20191206_131800Opposite the Settee on the far right here, Selim has removed the top of the cabinet for the two side by side freezer drawers and taken it back to the Cabinetry Workshop.
IMG_20191206_104306Once he has these solid edges attached and trimmed flush, he will take it over to the big veneer press and apply the veneer sheets he and Omur have so carefully chosen.
IMG_20191206_160959Over on the other side of the Cabinetry Workshop, Omer, perfectly framed by this cut out in the wall panel that goes on the outboard side of the stairs leading down into the Master Cabin, has been making great progress on the complex little cabinet for the sink in the Guest Head/Bathroom.

Master Cabin HeadWe’ve made quite a few changes to this early rendering of the Guest Head and my apologies for not having an updated render to show you but if you do a mirror flip of this render in your head (sorry) you’ll be close to the new layout.
IMG_20191206_104206Omer is demonstrating how the countertop with the sink setting atop the right end will appear to float above the cabinet below and if your mental gymnastics worked well, the image in your head should augment the reality you’re seeing here.
IMG_20191205_143622Earlier in the week it looked like this with the sink area on the left and the L-shaped that runs down the side of the Head and then wraps around to create a handy shelf behind the VacuFlush toilet similar to what you can see in the original render above.
IMG_20191205_143635A good example of how the solid Rosewood is glued up to create the large radius corners and the sink surround edges.
IMG_20191206_132652Which soon looks like this as Omer turns his attention to the veneer he has chosen for the wrap around countertops.
IMG_20191205_143717He has also fabricated these two large radius corner posts for the cabinet below the sink.
IMG_20191206_104119Which he is gluing up here.
IMG_20191206_104132Closeup of those large radius corner posts now glued with reinforcing biscuits into the completed under sink cabinet.
IMG_20191206_160818Here is how the countertop and sink cabinet will fit together. 

Mr. Geeeeee gets a Beautiful New Mechanic!

IMG_20191202_121020_MPMr. Gee as we affectionately call our mighty Gardner 6LXB engine has also been getting some much needed time and attention the past few weeks so let’s catch you up on that.  Since she returned from her short sojourn in Spain two weeks ago, Captain Christine has added new title to her already long list by becoming Mr. Gee’s new mechanic!  With Commodore Barney thankfully supervising very closely.
IMG_20191207_141759_MPCurrently Mr. Gee more closely resembles Humpty Dumpty as he is all in pieces again after being put together briefly for a complete sandblasting of all his external parts.  Now we are busy cleaning up all the internal parts which have accumulated over the 50 years of his previous life in powering a tugboat on the Thames River in England.
IMG_20191205_144346Christine has these valve lifter assemblies all cleaned up and ready for their new life as the heartbeat in Möbius.
IMG_20191019_103815Looking back a few weeks, this is what Mr. Gee looked like after giving him a very thorough sandblasting and several coats of high temperature silicone based primer.

Ruby the Wonderdog on the left and Barney the Yorkshire Terror always on duty supervising every step of the way.
IMG_20191019_121649Loosing his head, two cast iron ones in fact, each of which must weigh at least 70kg/150lbs, next up for removal is the cast iron cylinder block sitting on top here.  I had previously removed the old cylinder liners and had new ones pressed in and machined to finished size so they are all ready for their equally new pistons and rings.


One of the great things about these Gardner engines and what makes them surprisingly viable for reuse is that while complete engines are no longer being manufactured almost every part is still being made and available from Gardner Marine Diesel which carries on the Gardner name and heartbeat.  So with the exception of the primary castings such as the cylinder block, crankcase, and crankshaft I was able to buy every other part new from pistons and rings, to every bearing, every gasket, fuel injectors, etc.  Once Christine and I have him fully scrubbed clean we begin to put Humpty Dumpty back together again and bring Mr. Gee back to his original glory or better.


IMG_20191206_164537I have Mr. Gee fully disassembled for about the fourth and hopefully final time since I first picked him up in England two years ago.  Here he is stripped down to just his all cast aluminium crankcase. 
Next week I’ll take him outside for a thorough de-greasing and pressure washing to flush out every nook and cranny to get rid of all the accumulated oil sludge and the sandblasting sand that has crept inside.


IMG_20191207_141748Yesterday I tackled the truly massive crankshaft by scrubbing every surface and all the internal oil galleries with degreasing liquid and LOTS of paper towels.  Old on the right, partially cleaned on the left.
IMG_20191207_163006About 3/4 clean now before getting a good pressure wash and some new fibre discs in the torsional damper on the left end. 

Visible below the crankshaft is the Cast Iron cylinder block with its new liners and ready for its equally thorough cleaning and prep for reassembly.
IMG_20191206_170223Old meets new! 

The shiny new aluminium ring I’m holding in front of Mr. Gee’s massive marine flywheel is the outer Centamax ring that transfers Mr. Gee’s rotational torque of the spinning flywheel to the Nogva CPP input shaft.
IMG_20191014_161048Easy to see how simple this Centamax flex coupling is with the outer aluminium ring’s fingers fitting tightly into the matching grooves in the thick rubber disc bolted to the Nogva’s input shaft.  The grey cast aluminum housing on the left is off Mr. Gee and mates perfectly to the the matching SAE bolt pattern on the red Nogva servo box.
IMG_20191206_170129Fortunately for me, the Society of Automotive Engineers or SAE began creating standards for things such as threads and bolt hole patterns back in 1905 and are still being used to this day quite universally and ubiquitously in the manufacturing world globally.   Gardner and Sons Ltd. was founded in 1868 and began building engines in 1895 and so they were amongst the very first to adopt SAE standards for their engines.
IMG_20191206_170140Sound boring?  Well not to me!  Our union of old and new provides a great example of why such standards matter an enable me to simply bolt our almost 50 year old Gardner 6LXB engine to our brand new Nogva CPP using in this case the SAE14 bolt hole pattern to fasten the new Nogva/Centamax ring to the Gardner’s flywheel.
Gardner Marine Diesel EnginesMichael Harrison now runs Gardner Marine Diesel after his Dad retired after working for Gardner and Sons Ltd for most of his working life and then started Gardner Marine Diesel when he bought the entire inventory and much of the machinery when Gardner and Sons closed shop in the early 1990’s.
IMG_20191206_170113Michael not only found Mr. Gee for us when he was being removed from that tugboat so they could upgrade the tug to the more powerful 8LXB for the tugs newly upgraded job requirements, but he also found this original solid steel marine flywheel “blank”. 
Next week this flywheel will be machined with the SAE14 bolt pattern on this outer face so I can bolt the Nogva/Centamax ring to it prior to mating the Gardner with the Nogva and lifting them into their new home in Möbius’ Engine Room for the first time.  Just a wee bit eXcited about that and so stay tuned for more in the coming Weekly Progress Updates.

But WAIT!  There’s more!

NEW ARRIVALS @ Naval Yachts

IMG_20191113_141331Remember that crate Christine & I built when we were back in Florida last month?
IMG_20191114_230148IMG_20191115_092408and then filled with the many, many, many parts which we had been ordering and sending to our Florida addresses?
IMG_20191115_000635IMG_20191115_161428And then trucked down to Miami to have it air freighted over to Naval Yachts?

IMG_20191207_120152Well, it showed up here on Friday!  We’ll have great fun unpacking it and showing you all the contents next week.

But WAIT there’s even mooooooooooore!!!

IMG_20191206_133203_MPLook what else showed up on Friday!!

Can you guess what’s inside THIS crate and why our brilliant interior designer Yesim is almost as excited as we are about it?
IMG_20191206_133153This should help you guess?
IMG_20191206_135842Do Hakan and Yesim help you get your guesses warmer?
IMG_20191206_133211Or a peek inside perhaps?
IMG_20191206_140450Good Guess!!  It is our eXquisite Galley countertops which have all be cut from this slab of Turquoise granite at Stoneline.
IMG_20191206_135918It arrived at the end of the day on Friday so we only had time for a quick inspection and we’ll show you much more as it gets installed in the coming weeks.
IMG_20191206_135847But we were able to see the bullnose rounded edges and some of the other details and can’t wait to inspect it fully tomorrow.
and I promise it is the LAST time for this week but ……………………………………

WAIT!  There is just ONE more HUGEY thing to show you………………………………

Christine and I regard ourselves as two of the most fortunate people on the planet because we are surrounded by the most awemazing friends who, in addition to being very good friends, also have talents you just wouldn’t believe.  One of dearest friends and most talented artists we know is pictured below, the one and only Sherry Cooper. 

Sherry working on shower glass imagesSherry and I first met back in 1981 when she and her husband Rick arrived in Baden Baden Germany where I was living at the time.  I was a High School teacher for the Canadian Air Force jet fighter base there and Rick joined us from his English teaching gig in Vancouver BC.  In addition to teaching there for the next three years we all traveled extensively throughout Europe, Africa and beyond and our friendship continued to grow ever since.

And I am I telling you this because??


03 - CopyBecause Sherry agreed to put her incredible artistic talents to work and design the patterns for those two plate glass walls that form the corner of our Master Cabin shower that you may recall seeing in some of the early renderings of the Master Cabin.

Plain clear glass just wouldn’t fit with the eXtreme beauty aboard Möbius now would it?  Plus, unlike me, Christine has a modicum of privacy and wasn’t thrilled by the idea of being on such a well lit stage when she was showering.  So we came up with the idea of having the glass etched with some fun and beautiful pattern.  But where would we find such a pattern? 

Ha!  Easy peasy as some of my Canadian friends might say, we mentioned it to Sherry on one of our visits and she delighted us by jumping at the chance to be so involved with the creation of our new home.  Several meetings and lots of Emails later we evolved the idea of having a theme that would involve some of the art and imagery of the Aboriginal Peoples of Möbius’ Home Port of Victoria BC.  The term “Aboriginal” refers to the first inhabitants of Canada, and includes First Nations, Inuit, and Métis peoples. This term came into popular usage in Canadian contexts after 1982, when Section 35 of the Canadian Constitution defined the term as such. 

Then we asked Sherry if it might be possible to incorporate some pictures we so vividly recalled from her prodigious photography work of some otherworldly reflective waters where she and Rick have their boat near Gambier Island?  Of course she said!


My apologies to you Sherry for this amateurish picture of your pictures, but really people, can you believe that these are untouched photos Sherry took when she spotted these patterns being reflected in the water as Rick was docking their boat??!!!


So what did Sherry come up with?

Check out what we awoke to find in our Email inbox this morning!

We will now be having one of these images etched into each of the two plate glass shower walls and can’t wait to show you the results when they are done and installed in the Master Cabin.

You are AWEMAZING Sherry!  Thanks and just let us know when you are flying over to come see your work on display inside Möbius!

OK, as promised that is finally it for this week’s update.  See what I mean about that conundrum of time?  How could so much happen in so little time?  But it did and I have the photos above to prove it!

Black Water & Clear Glass–XPM78-01 Progress Nov. 25-29, 2019

Black Water & Clear Glass–XPM78-01 Progress Nov. 25-29, 2019

It has been Thanksgiving week for all our American friends and family back in the USA and while Christine and I are far away and Canadian Thanksgiving was over a month ago, we will take any opportunity to remind ourselves just how many things we have to be thankful for.  Working on XPM78-01 Möbius this past week here at Naval Yachts has been filled with many such reminders that I’ll show you in this Progress Update.  What I am personally most thankful for thought is that my Beautiful Bride and Captain Christine is now finally back in my arms after spending a week in Spain where she was doing some boat and pet sitting for some very dear friends who have their boat enjoying a lovely little marina for the winter in Sant Carles de la Ràpita which is about 3 hours drive SW of Barcelona.

But I”m sure you are much more interested in all those many other things we have to be thankful for this pas week onboard Möbius so let’s go check all those out.

CABINETRY:

I’ll let Cabinetry work take the lead this week for a change which is easy to do given all the progress those two teams made this past week.

IMG_20191128_144921Some of you have been asking how all those mesmerizing swirling grain patterns in the Rosewood are all so beautifully aligned and flow across the different cabinetry components and this shows you one way this is done. 

IMG_20191127_141811Omer has picked out a series of matching slices of Rosewood from the stack you see above, carefully aligned them into this series and temporarily taped them together.
IMG_20191127_142111Next he lays one of the long vertical pieces for the doors and walls in the Guest Shower and Head/Toilet area on top of these strips and uses the edge to guide his razor knife to crosscut the piece of veneer a bit larger than the board it will soon be glued to.  After a short trip to the big heated veneer press, the board is ready for its solid wood edges and further machining.
IMG_20191128_103618In a case such as this piece, the bottom side has Rosewood veneer and the top surface has Beech laminated to them and then the edges and corners are machined with their respective radius, dados/grooves, and rabbets.
IMG_20191128_165843The result? 

This kind of matching grain patterns flowing horizontally across multiple pieces and around corners. 

In case you don’t recognize it, this is the Guest Shower you are looking into with the Guest Cabin to the left and the WT door into the Workshop/ER on the far right.  The shower door itself will be all glass in this case.
IMG_20191125_101506_MPStanding in the Shower and looking across the entryway to the Guest Cabin is another example of the matching grain patterns on this outer wall of the Guest Head in the corridor leading up the stairs to the SuperSalon.
IMG_20191125_101430From the same spot just rotating counter clockwise to Port/Left side of the hull a bit you can see how my “clean workbench” and Office area is shaping up with lots of storage areas above and below the workbench.

Dual Fridge cabinet with more examples of the matching Rosewood is at the top of the stairs.
IMG_20191126_144456This is what you’ll see coming down those stairs from the SuperSalon looking aft into the Workshop/Engine Room with the Workbench/Office along the hull on the right and Shower/Head on the left.  The cut outs in the upper half of each wall are where the padded light gray leather panels will go with the Blue Horizon line and handhold separating the upper leather and the lower Rosewood.
Corridor workbench   StairsThis is a rendered approximation of what this Workbench/Office area will look like when finished.
IMG_20191126_102311For one final perspective I scrambled up the stairs into the SuperSalon and put the camera down on floor level looking Aft to catch this view of the Fridge cabinet on the right and the inside peninsula cabinet of the Galley on the left.  You can see my workbench/Office area in the distant background between the stairs and the Fridge cabinet.
IMG_20191125_102758Next door to the shipyard is Naval’s Cabinetry workshop and over there we find Omur and Selim continuing to make good progress on the smaller cabinets which run along the back edge of all the countertops.  I refer to these as the “Garages”.
MOBIUS_SALOON_RENDER (6)This render looking over the Galley to the Stbd/Right side windows lets you see how these Garages are mounted on top of the rear edges of all the marble countertops.
MOBIUS_SALOON_RENDER (4) - CopyThis bird’s eye view shows how there are four banks of these Garages surrounding the Galley providing a lot of super convenient storage at your fingertips.  Note that the depth of these Garages are all different to provide different amounts of countertop area in front of them and different sizes to each Garage that can be maximized for their contents.
IMG_20191129_125407One of the keys to make these Garages super efficient is to make access super quick and easy and so we have created these “gull wing doors” work like this with the top and front surfaces being made into a single piece that hinges at the back and latches at the bottom.  There are small gas assist cylinders inside so you just lift the latch and the door swing up and out of the way.
I’m quite a car buff and part of the inspiration for this door design comes from one of my all time favorite cars, the 1956 Mercedes Gull Wing 300SL Roadster.  I couldn’t ever afford this model but at one time I had two of the sister 190SL’s I brought back with me from living in Germany in the 80’s.
IMG_20191125_102805My grizzled hand and the spray can provide a sense of scale of this set of Garages which go along the the countertop that runs athwartships/side to side, with the dining settee behind and the Stbd/Right windows on the right end.

IMG_20191128_103514This is the long bank of Garages running along the Stbd/Right side with their back edges up against the window glass.
IMG_20191128_143834_MPSelim putting the solid Rosewood edges on one of the Gull Wing Doors with the bank of Garages in front that run along the windows on the aft end of the Galley.
IMG_20191128_144851Omur has three of the four banks of Garages laid out on this platform as they will be placed in the Galley so he can cut the very complex set of angles for the mitered ends where two banks intersect.  The bank on the floor on the far right fits into the spot where Omur is standing. 
The bottom corner here is where the Aft on the left and Stbd Side windows on the right meet and the short bank of on the right side of the platform is the one with the dining settee behind (to the right) of it.


IMG_20191128_144043Looking from the other side now that Omur has this corner miter roughed in you can see how the bank of Garages will connect to each other.  The short bank on the left is again the one with the settee behind it on the far left side.


Once all these banks of Garages have been fully fitted into the boat they will come back here to have all the Rosewood veneer applied to their outer surfaces and have all their solid edges machined with their radius corners.


PLUMBING:


IMG_20191125_101248Cihan continues his progress with things like getting the Day Tank fitted on the Stbd/Right side of the Engine Room Enclosure so he can now start running all the diesel fuel lines going in and out of this Day Tank.


He has also been running more lines along the sides of the hull such as the Chiller lines wrapped in black EPDM insulation on the bottom here, clear water lines above them and then hot and cold supply lines running up vertically on the far right where they then run across the ceiling over to the other side.

IMG_20191125_101256As each new section of plumbing is installed it is checked for leaks with compressed air and this pressure gauge.  Doing this testing at steps along the installation process is more time consuming but makes it much easier to find any leaks that might show up rather than waiting till the whole circuit is installed and having to track down any leaks along the whole run.
IMG_20191129_155422In the Forepeak up at the other end of the boat Cihan was busy installing the second Black Water (sewage) Holding tank with the VacuFlush Vacuum Generators underneath.


These Dometic BW Holding tanks are a very complete BW Holding Tank system with the diaphragm pump on the right for pumping BW over to the exiting Sea Chest barely visible on the far right end of the tank by the black/red wires and a second independent exit for a shore side pump out connection in the center with the white/green sanitation hose connected.  Well designed with all hoses coming in/out of the top only so there are not any hoses that retain sewage when not being used.  The black cylinder on the far top edge is a vent line filter and the round disc to the right of this is a vacuum release valve which prevents high volume shore side pump out stations from collapsing the tank sides with too high a vacuum inside the tank.  And on the left middle those wires are for three float gauges that connect to green/amber/red lights for empty/mid/full indicators.  We will also install a digital tank level sensor using Maretron submersible pressure sensors that put the precise tank level information onto the NMEA2000 network so we can see and display that data on any monitor throughout the boat or on our phones and tablets.


IMG_20191129_124058These 150L/40 USG holding tanks can weigh up to 160kg/350 lbs so they need to be very well supported and you can see how Cihan has welded in T-bars under the reinforced bottom stringers molded into these Dometic BW tanks.


These T-bars are further strengthened with the AL plate he welded in to mount these two diaphragm low water Bilge pumps.  And the space under the BW holding tank provides a nicely sheltered home for the VacuFlush Vacuum Generator.


WIRING:

IMG_20191126_144200While it may look like Hilmi is laying down on the job he and Okan are actually hard at work putting in this DC junction box for lighting up in the SuperSalon and forward Master Cabin.  This is located on the right side of the stairs going down into the Master Cabin where the 43” monitor will later be installed.
IMG_20191127_141249Just roughed in here but you can already see that Hilmi does very neat and well detailed wiring of all our electrical systems and is now taking full advantage of all those cable trays he installed a few months ago.
IMG_20191129_104022Looking aft from that Junction box you can see one of the many benefits of this design with all this volume running down both sides of the SuperSalon where the side decks run overtop.  These volumes provide unprecedented space that makes installation and future maintenance a breeze as well as providing areas for mounting equipment we want to keep out of the way such as the AC Chiller Air Handlers.
IMG_20191129_123829More of Hilmi’s handiwork is seen here along the Stbd/Right hull in the Master Cabin where he has now installed the four massive Red/Black cables that bring all the 24V DC current up to the Forepeak to run things such as the Bow Thruster, Windlass and Kedging Winch.
IMG_20191129_103948Each of these cables are120 mm2 / 4/0000 to ensure less than 2.5% voltage drop from the batteries.
IMG_20191129_123825For those wondering, these high amperage cables are purposely twisted to help reduce the magnetic fields that are created around each cable whenever current is flowing. 
Fig 7 & 8 Minimizing EMI with twisted cablesThe direction of these circular magnetic fields is in one direction for the red positive cable and the opposite direction for the current flowing the other way in the black negative cables so twisting them slightly like you see here helps cancel the magnetic field out. 

Why do we care? 

Magnetic fields can negatively affect things like compasses and more so interfere with current flowing in other nearby wires so as you can see we also keep these high amp DC cables in their own cable trays mounted as far away from other wires such as AC lines and then we keep data carrying cables even further away and over on the opposite side of the boat wherever possible.

ALUMINIUM WORK:

Uğur and Nihat are relentless in their pursuit of completing more and more of the seemingly endless list of aluminium work to be done and this week was no exception as they finished dialing in the prop tube and started working on the aluminium framing for the glass surrounding the SkyBridge coamings.  Let’s go check it out.

IMG_20191126_101956Using all the measurement tools available from low tech string lines and tape measures to laser levels and dial indicators, the prop tube was brought into full alignment in preparation for being permanently attached to the hull. 

Here Uğur is getting a line representing the centerline of the rudder post precisely positioned so measurements can be taken from that to other parts of the CPP propeller, prop shaft and keel.
IMG_20191126_102048Nihat is sitting directly above Uğur inside the very aft end of the Workshop adjusting the position of this centerline extending down through the hole where the rudder post bearings will mount.
IMG_20191127_105135Using these reference lines they were then able to move the inner Nogva CPP prop log tube with precise and tiny increments by tightening and loosening these four screws to move the tube up/down and left/right until it was in just the right position and then do the same at the other end inside the Engine Room where this tube and the prop shaft enter.


The vertical pipe on top is where the epoxy like ChockFast liquid will be pumped into the space inside between the two tubes and once it is fully filled will be left to harden and lock the whole assembly into one solid component for the prop shaft to run inside.  Now we wait for the ChockFast to arrive for the next stage.


IMG_20191126_130825Next up they started to remount the workbenches and shelves that run the full length of both sides of the Workshop.  Just the lower shelf has been installed on the right to give more room for Cihan to finish plumbing the Day Tank, Chiller pipes and other lines on this side.

But you can see how the Workbench and shelves will look the same on the opposite side.
IMG_20191126_102130Moving up to the WT door leading into the Workshop from the Guest Cabin area to get this shot looking aft to give a better sense of just how much shelf and workbench area these provide.
PH Vent Tunnel under solar panelsThe big new job they started this week though was putting in the AL framing for the clear glass “eyebrow” that runs around all four sides of the SkyBridge.  This raises the height of these partial walls or coamings from about knee level to almost waist level for greater safety but without affecting the 360 degree views when looking out.
IMG_20191127_140534_MPAt the four corners up front there will be tubular supports to both support the forward end of the SkyBridge roof as well as provide frames for the acrylic sheet windows. 
IMG_20191127_161057_MPFirst job was to tack the lower socket portion of these pipes in place atop the flat tops of the front AL coaming.
IMG_20191127_161109The framing for the glass panels which will be glued in place with industrial glass adhesive similar to what is used in building high rise glass sided buildings, is fabricated from L-bar so that was tacked in place next.
IMG_20191129_104146_MPIt is important that the top surface of the glass frames are perfectly level and on the same plane as this will also be the surface that supports the roof when it is lowered down into “cyclone” or “canal” mode and the laser level makes that very easy.
IMG_20191129_104125They are a well oiled team and they quickly worked their way around the whole perimeter tacking the L-bar in place. 

More to follow next week so stay tuned!

  But WAIT!  There’s more!

Several surprise guests showed up and added to the things we have to be thankful for.


IMG_20191129_112516First was this crate which Yigit is busy removing the top from.

Any guesses as to what’s inside????
IMG_20191129_112809Some of you will know immediately when you see this and for those not familiar these three white tubes are the membranes for our watermaker.
IMG_20191129_113703Underneath is this beauty, the heart and soul of the watermaker containing most of the other components such as the high pressure water pump, the pre filters and the gauges for low and high pressure as well as salinity and product water (pure H2O) flow rate.
IMG_20191129_113735Back side has the insulated high pressure lines carrying the seawater into and out of the high pressure pump and you can se one of the filter housings on the left end.
IMG_20191129_113822Not too heavy so quite easy to bring all the components up the stairs and into the Workshop.
IMG_20191129_155225The watermaker will actually go directly opposite of here but as you saw earlier, that workbench isn’t installed yet so we set all the components on this side just to check out the fit on the workbench.


The 3 membrane tubes will mount up on the wall behind the WM and on the far right is the remotely mounted low pressure feed pump which brings sea water out of the Sea Chest into the High Pressure pump. 

Hard to see but the main control station box is wrapped up on the far left side.

I was delighted to be able to source this watermaker from a Turkish Company just north of us as one of my very best friends and fellow liveaboard cruiser had great experience with the watermaker he got from them last year for his boat.  The key thing with Watermakers for me is that ALL the components be “generic” off the shelf items rather than proprietary ones as this makes it so much easier to find replacement parts anywhere in the world as needed over the years.  Fortunately Watermakers have gone this way and everything from pumps to membranes to switches and gauges are all industry standard items that can be found almost anywhere.

For those interested in some of the technical details, this is a Delfin “Maxi 4500” and some of its specs are:

  • Ceramic piston high pressure pump
  • Powder coated aluminium frame
  • 316L SS high pressure control valve
  • 316L SS by-pass valve
  • 316L SS low and high pressure gauge
  • Fresh water flow meter
  • Sea water flow meter
  • Low pressure switch
  • TFC membranes
  • FRP membrane housing
  • 316 SS high pressure fittings
  • 25&5 micron pre-filter
  • Manual fresh water flush
  • Operation time indicator
  • Automatic salinity monitoring and bad product rejection
  • Feed pump

The pumps are all 220V AC and the membranes are standard 2.5” x 40” size which produce 190 L/50 USG per hour.

It was also important to me that our watermaker be all manual rather than all automated.  We are eXtremely dependent upon our watermaker for both potable/drinking water as well as all our domestic water and water we will need to produce during passages to use as ballast to replace the weight of the fuel as it is used.  This added to the challenge of finding the just right watermaker because the trend has long been to make these more and more fully automated where you just “set it and forget it”.  No thanks, I’d much rather start up and shut down our watermaker each time so I know for sure how it is working and can adjust it for optimum output and operation as sea temperature and salinity change and require different settings.

But WAIT!  There’s still MORE!

Hilmi, our electrical whiz, came and asked me to come off the boat with him to check out the new pallet of equipment that had just arrived.

IMG_20191129_160516Which turned out to be THIS pallet full of beautiful blue Victron boxes!

I will go over this in MUCH more detail in the coming weeks but at the risk of causing some serious drooling by some of you, I’ll just leave you with the following photos of what’s inside some of these boxes………….

Go BIG and Go Home! XPM78-01 Möbius Progress Update Nov. 18-22, 2019

Go BIG and Go Home! XPM78-01 Möbius Progress Update Nov. 18-22, 2019

Finally catching up with some of the backlog after my 3 week trip back to Florida, BC and California and able to bring you up to date as of Nov. 22nd, 2019 on the continued progress in building our XPM78-01 eXtreme eXpedition Passage Maker aka Möbius at Naval Yachts here in the Antalya Free Zone in south central Turkey.

Lots to show you find a comfy seat and a good beverage and let’s take a tour through all the work Team Möbius accomplished during the week of Nov. 18-22, 2019

RUDDER:

By far the most exciting work this past week has been the test fitting of the Rudder and the CPP or Controllable Pitch Propeller system.

IMG_20191118_102357Contrary to the popular saying “Go Big or go home” we’ve decided to do both with this beautiful big prop that will take us to wherever we want home to be that day.  Four blades as you can see with an OD of 1m/40”.


Show is always better than tell so check out this quick little video with Uğur showing how the pitch changes as the four blades rotate in unison.

I will cover the CPP system in much more detail in the coming weeks but it is a very simple system and one that is used in workboats worldwide for decades although not something that is too well known in the North American and recreational boating markets for some reason.  As you see in the video the blades can pivot on their bases inside the hub and this rotation is caused by a simple small diameter 12mm/ 1/2” push/pull rod that moves fore and aft sliding inside the prop shaft.  This push/pull rod extends out of the prop shaft inside the boat and is threaded into the center of the flange on the CPP servo gear box which uses hydraulic pressure to push/pull the rod as you move a simple lever in the Helm station.

Why you might ask?  Well, simple explanation for now, from your equally simple author, is that a fixed pitch prop which is what most of us would be most familiar with, is pitched to be just right at one RPM and one set of conditions.  At this point the prop is at maximum efficiency and is probably a little bit more efficient than an equivalent CPP system.  BUT, at any other speed of the boat or the prop and in any other conditions, the CPP can change the pitch to be just right all the time.  This allows us to dial in the perfect pitch and hence perfect engine loading and fuel burn at any speed we want to maintain in most any conditions.  Maximum efficiency translates directly into maximum fuel economy and maximum engine life so you can start to understand the appeal and why we went this route.  And without getting into the details, contrary to what most would think and I did too initially, if you are building a new boat the cost of a CPP vs a fixed pitch prop is about the same.

One last fun fact for you about our CPP system is that the gearbox is also simplified because it is only providing the 3:1 gear reduction and there is no need for any forward/reverse gearing or shifting.  Huh???  Say what???

Simple really, while there is a clutch that we can switch on/off to engage/disengage the engine from the prop shaft, most of the time we don’t bother.  Instead, the prop is spinning pretty much anytime the engine is running and neutral is established by setting the pitch to zero.  Think a knife on edge cutting through the water.  When you want to move forward you move the CPP Pitch lever in the Helm forward and the pitch now changes as the lever moves the push/pull rod and the boat moves forward.  The further you push the Pitch lever the faster the boat moves as the thrust builds with the increased pitch.  Pull the lever back to the straight up and down (typical) position just as you would do on a traditional throttle lever and you are back at neutral.  Continue to pull the lever back and the boat moves aft.

This gentle feathering of moving forward and aft rather than the “clunk” of shifting between Neutral/Fwd/Reverse on a traditional transmission and fixed prop adds to both the ease of close quarter maneuvering and the life of the propulsion system.   As you can tell we are REALLY looking forward to trying out CPP system out once we launch and we’ll bring you along for those rides too.  Now, back to work

IMG_20191118_105539Appropriately pleased with himself Uğur now has the partly finished rudder slid into place inside the hull and set into its position so we can double check all the many dimensions that are part of getting the overall propulsion and steering systems just right.
IMG_20191118_105653_MPThis is the first CPP system Nihat or Uğur have installed, (mine too!) so it was a very fun experience getting all these components test fitted in place.
IMG_20191118_110013This is what things look like On the other end of the prop shaft inside the Engine Room.  You can now clearly see that threaded push/pull rod as it exits the 65mm/ 2.6” diameter prop shaft.  Changing the pitch is as simple as moving this rod forward and aft.
IMG_20191122_150441Once we had assured ourselves that all the dimensions and clearances were spot on, the CPP prop and shaft assembly were slid out and set aside for the next big operation which is affixing the CPP prop log perfectly centered within the prop shaft tube of the hull.

It might look like a crime scene but the tape is just there to prevent anyone from walking into or disturbing the lines and lasers used to set and align these two tubes concentric with each other.


IMG_20191122_123436The large machined cylindrical end with the holes in it is the aft end of the Nogva supplied prop log tube which then extends about 2m/7ft up inside the outer prop tube welded into the hull.  The goal now is to get these two tubes perfectly aligned with each other and then a special epoxy liquid will be pumped into that vertical pipe you see here and fill up all the space between the two tubes. 
Once hardened the two tubes become one and we only get one chance at this so we are taking time to check everything multiple times and get everything lined up before pumping the ChockFast into the void inside.


IMG_20191122_122619At the other end inside the Engine Room, Uğur has tacked in place this aluminium ring and using four short bolts, similar as to what you see in the photo above, these screws are turned to bear against the inside prop log tube and move it up/down/left/right to position it just right.


The clear tube taped to the bulkhead is where the ChockFast will exit the inner void as it is pumped all the way up and we’ll know that the whole space is filled and can be left to harden.


IMG_20191122_123423This close up shot lets you see all the way through the machined Nogva prop log tube to the Engine Room.
IMG_20191122_120446There are a lot of interrelated dimensions and measurements we need to take to ensure that not only is the prop shaft properly aligned within the tubes but that it is also alighted with the center of the Rudder Shaft and that the CPP prop is also aligned with and spaced away from the leading edge of the Rudder blade and the trailing edge of the of the Skeg plate. 


Here, Yusef is double checking the line marking the center of the prop shaft with the vertical centerline of the Rudder shaft, both of which have been set and checked using the ubiquitous laser level.


Be sure to stay tuned to this channel for next week’s episode of “As the Prop Turns”.

PLUMBING:

IMG_20191118_102601I covered much of Cihan’s work on the plumbing in the previous weekly update but here we find him installing all the valves on the diesel Day Tank.  The Day Tank is on its side here with the bottom facing us and you can see the round sump that has been welded in to provide an out of the way spot for any water or dirt to accumulate and then be easily checked and drawn off into a small container by opening the ball valve.
IMG_20191118_102731The other ball valve near the middle here is the main take off for both our two diesel consumers; Mr. Gee our might Gardner 6LXB main engine and our Kabola diesel fired water heater.

The elbow at the top will feed a sight tube that goes up this outside corner of the tank and gives us an always accurate, always there fuel gauge.


Cihan is attaching the bottom access port for annual inspections and cleanouts if needed.


IMG_20191118_103036Completing out Day Tank tour today up on top we find three valves controlling the input and outputs to the tank and the bosses on the far right for fuel gauges, one a submersible Maretron pressure sender and the other a mechanical Tank Tender type gauge.

CABINETRY WORK:

I was particularly delighted this week to see more progress on “my” Office and “Clean Workbench” space. 

Corridor Head Shower Guest Cabin Layout labelledFor orientation, this cutaway rendering shows the layout of the Aft Cabin on the right, Head & Shower to the Left and then my workbench and office space on the far Left up against the Port hull.


The Corridor connects the stairs coming down from the SuperSalon and takes you to either the Guest Cabin on the left or straight through the WT door into the Workshop and Engine Room.


Corridor workbench   StairsThis more realistic rendering, with the Guest Shower removed for clarity, shows what a great little office this will be for me or others to take advantage of.
IMG_20191118_103224And here is what the real thing is looking like so far.  Overhead storage cupboards, plenty of drawers under the workbench and a large opening in the center for the swivel out chair.  WT door into the Workshop/Engine Room is on the left.
IMG_20191118_103217Swiveling to the right to show the forward end of this Corridor area, the wall for the Head is not yet in place so you can see the large cupboards flanking the stairs as they wind up to the SuperSalon level.  These two cabinets alongside the stairs will be primarily AC and DC electrical distribution panels with switches, circuit breakers and such for the aft area of the boat.
IMG_20191120_122715Stepping just inside the WT Door into the Workshop/ER area and looking forward gives a good sense of just how large the Port side Office area is going to be. 

Not that I am at all excited about this.
IMG_20191118_103541On my way up those stairs to the SuperSalon as I came to the new cabinet for the 2 Fridges, I just had to try out these super cool, not that I’m biased, hand holds that run throughout the whole interior and will have an illuminated “Blue Horizon Line” on the inside surface.
IMG_20191118_103626_MPStanding in the Galley looking across to the Port/Left side you can see how this Fridge cabinet begins where the stairs end and then transform nicely into the two drawer Freezers that are tucked into the big space under the side decks of the hull.


This was partly inspired by one of our dear friends, Sue, when she commented a while back that she really liked the whole SuperSalon layout but wanted to know where she would be able to put her Martini glass when in the lounge chairs that sit on the far right area in this photo???

The top of the Freezer cabinet is your answer Sue and we can’t wait for you to come try it out in person.


IMG_20191118_104322I haven’t hand time to do any video tours lately so until I do, I’ll spin around the SuperSalon with some still shots to give you a better sense of the overall layout and relative sizes.

Standing in the forward Starboard/Right corner of the SS looking aft and to Port provides this view of the Freezers on the right, Fridges and under drawers on the left and then the stairs up to the Aft Deck or down to the Guest Cabin.  Corner of the Dining Settee in the bottom left.
IMG_20191118_104330Moving over to the middle of the SS about where the Helm chair will be lets us look directly aft and see how the whole Dinning area, Galley and Fridge/Freezer cabinets look.  Now imagine this with sparkling blue tropical waters and some palm trees on the nearby uninhabited island visible out all that 360 degrees of glass.

IMG_20191118_104335Standing in the same spot but looking over to the Stbd/Right side a bit gives a sense of how spacious the Dining Settee will be.  Stairs leading down to the Master Cabin on the far left.
IMG_20191118_110845Continuing to swivel left and now looking forward this is an early mock-up of the Main Helm area and you can see through to the Master Cabin below.  The blue is rigid foam insulation ready to be routed for the PEX heated flooring tubing to go in.
IMG_20191122_123254Moving Aft and climbing up the stairs to the Aft Deck lets me give you this slightly aerial view of the whole SuperSalon.  As I hope you may be starting to see, calling this the Super Salon was an obvious call.
IMG_20191122_113637Now let’s take a walk over to the Cabinetry Shop to catch up with the team over there and see what they’ve been working on this week.

Yeşim and Ömer are discussing details of this latest example of the gorgeous grain of the Rosewood.  Can you guess where this panel will go?
Entry to Guest Cabin Head ShowerFull marks to all of you who guessed this wall on the inside of the Corridor we were looking at earlier opposite my Office/Workbench.  Entrance into the Guest Cabin in the center with the Head on the left and Shower on the right and then the WT door leading into the Workshop/ER on the far right.
IMG_20191122_113717Here is that wall panel now right side up as Ömer shows us how he proposes to create the corner door frame for one of our “Swiss Doors” which close into a door jamb on both sides.  In this case this one door can close in the Head or the whole entrance into the Guest Cabin.
IMG_20191122_114003Close up of two parts of the glued up door jambs ready for machining and laminating.
IMG_20191122_115638Over on the other side of the shop, we stop to discuss the above countertop storage which we refer to as the “Galley Garages”, with Ömür on the left, Yeşim middle and Selim.
MOBIUS_SALOON_RENDER (1)This render of the Galley in the upper left area will give you a better visual idea of what these Galley Garages will look like and how much storage space they will provide.  With 360 degree glass we don’t have any cupboards above countertop height so this was a way to have both lots of storage in the Galley and maintain those great views all around.
IMG_20191122_115645_MPThis is the prototype that Ömür has whipped up and we are going over with him.  The doors to the Galley Garages are a single piece made by joining the top surface and the angled surface you see here together into one piece.  The hinges go on the back side and there are small gas assist cylinders inside so as soon as you press the latch the doors swim up out of your way letting you see and reach all the way to the back without bending over.


You will soon see how this all works next week as Omur and team build these cabinets so stay tuned.


IMG_20191122_113526I’ll finish for this week with one last bit of Ömür’s craftsmanship, these beautifully executed grills which will be all around the SuperSalon directing the ventilation air, both hot and cold, into the room along the windows.  This is a quick prototype Omur put together for us to test out with air flow and looks.  We think we will make the final ones a bit wider and narrow the slats to increase the air flow and reduce the noise of the air flowing through them.

What do you think?

OK, that gets you up to date as of Nov. 22nd, 2019 with where we are at on the Good Ship Möbius.  Thanks for your patience in me getting these last two updates posted.  I don’t have any travel plans other than traveling off on Möbius early in the new year so I should be able to get back to timely weekly updates.

Great to have you along for the ride and please send in any and all questions, comments or suggestions in the “Join the Discussion” box below.

Thanks!

Slow & Steady: Progress Update XPM78-01 Oct 28-Nov 15, 2019

Slow & Steady: Progress Update XPM78-01 Oct 28-Nov 15, 2019

With apologies for taking so long to do so here finally is the long overdue weekly update for all you patient followers.

As you might recall from the last post, I flew to Florida to meet up with my Beautiful Bride Captain Christine who had been there for almost 6 seeks looking after a myriad of things from ordering boat parts, to updating her 100 Ton Captains license to being Gramma to our Grandson Liam.  I was there to help introduce Baris and Dincer, the brother owners of Naval Yachts to the US and the huge Ft. Lauderdale International Boat show known as FLIBS.  And then I had hundreds of boat parts to order, have shipped to us in Florida, make and crate it all up to be air freighted over to Naval and somewhere in there fly up to BC to see family and friends there, down to LA to have our CanAm (I’m Canadian, Christine’s American) with our similarly CanAm family and Granddaughters.

I had naively hoped to be able to find the time to keep up with these weekly updates while I was away for the past three weeks on a truly whirlwind tour of the US and Canada, but I came up against one of the only finite resources we have; time.  Still only 24 hours in each day, trust me I checked, and while I didn’t sleep too many of those 24 hours while away, there just wasn’t enough time left over after days and nights filled with time with friends, family and most of all grandkids on top of keeping up with Project Goldilocks both back at Naval Yachts and on a daily basis stateside ordering, shipping and packing literally hundreds of pieces and kilos of equipment and supplies to take back to Antalya.

I know, I know, ……….. excuses, excuses.  But let me plead my case just a wee bit by showing you just a few of the reasons why my time just got away from me:

IMG_20191107_164337Pausing long enough to take in another gorgeous Vancouver sunset with dear friends.

Well, you get the idea.  All just excuses I know, but you might admit some pretty darn cute and great ones and I wouldn’t have it any other way.
But let’s get back to boat building shall we?!!!!!

As you may have noticed in the title, I’m going to cover TWO weeks of progress for you here, spanning October 28th through November 15th, 2019 so hang on to your hats, grab a tasty beverage and let’s go fly through Naval Yachts shipyard and see what Team Möbius has been up to.

PLUMBING:

Let’s start with Plumbing Progress for a change and check in with Cihan to see what he’s been up to.

WhatsApp Image 2019-11-02 at 8.29.26 PM (8)Down in the Basement he has now mounted and plumbed one of two 150L/40 USG black water holding tanks,  This one in the Basement is for the Guest Head and …..
IMG_20191118_102519…. this one waiting down on the shop floor will soon be mounted in the Forepeak to service the Master Cabin Head. 

These are complete systems with a super reliable Dometic diaphragm pump, odor filtered vent and all the built in fittings.

WhatsApp Image 2019-11-02 at 8.29.26 PM (4)Next to the BW Holding tank Cihan as also mounted the vacuum generator that is part of our beloved VacuFlush toilet systems.  We had these on our previous boat and worked flawlessly for the 14 years I had her and we really love how well they work.
IMG_20191122_122706_MPHere is how these two components sit in the Basement, up against the WT Bulkhead with the Guest Head immediately on the other side so very short pipe runs even though these VacuFlush systems are built to have very long runs with no problem.
WhatsApp Image 2019-11-02 at 8.29.26 PM (5)As we do with all the equipment, the Holding Tanks and Vacuum Generators are isolated from the boat by mounting systems that keep them clear of the floor as in this case and also allow us to create vibration absorbing soft mounts where needed such as on the Vacuum Generator to ensure no noises from the pumps can transmit through the hull and interior.
IMG-8143These two diaphragm bilge pumps are another example of how we keep all components isolated from the boat.


For those unfamiliar with VacuFlush it is a system very similar to the way the heads on airplanes work.  The Vacuum Generator creates a vacuum between itself and the underside of the toilet bowl and so when you step on the foot pedal beside the toilet everything in the bowl is instantly pulled through the sanitation hoses, through the VG and into the Holding tank.  The Holding tank then has its own diaphragm pump to extract the contents out to the Sea Chest or to a pump out connection on deck for shore side pump outs.


WhatsApp Image 2019-11-02 at 8.29.26 PM (10)This manifold is part of the plumbing for the pump out of both the Gray and Black Water systems.  Given our typical sailing style we don’t usually need to use shoreside pump out facilities and can discharge when miles off shore through our Sea Chests so this manifold allows us to select between Sea Chest and pump out for the BW.


WhatsApp Image 2019-11-02 at 8.29.26 PM (13)More of Cihan’s handiwork in the Basement on the various Bilge pump plumbing.  Larger 40mm/1.5” hose is for the high volume Bilge pump system and the smaller 25mm/1” clear hoses and those two diaphragm pumps are for slurping up any small amounts of water that might find its way into those “gutters” formed where the tank tops are curved down so they can be welded perpendicularly to the hull sides.  Makes for a very tidy, effective and efficient bilge system.
WhatsApp Image 2019-11-02 at 8.29.26 PM (15)And Cihan makes it all the neater with his careful routing of all these hoses through the “super highways” of cable trays running throughout the boat.

CABINETRY:

Our awesome Cabinetry team of Omur, Selim and Ömer have been keeping up their always impressive progress as they build the cabinetry for the Galley, SuperSalon, Guest Cabin and Office areas so let’s go see what they’ve been up to the past 2 weeks.


TFDX4700One of the newest cabinets to get started are the ones for the freezers and fridges.  A bit hard to see through the blizzard of clamps perhaps but this is the cabinet for the two 130L/35USG Vitrifrigo fridges which will slide snugly into the two large openings and with two storage drawers below.

Reefer box ideas mob_r_01Yesim provided this quick render so you can see how all four units will look along the Port side of the SuperSalon.  This is a much more efficient and pleasing design that what you may recall seeing in previous renders where we have moved the two freezer drawer cabinets forward and tucked them out into the large space under the side decks. 
Keeps everything nice and low and makes both the fridges and the freezers much easier to access when you open them.


TOPN8272 Here is the cabinet for the two drawer freezers being assembled in the Cabinetry shop.
IMG-8177This helps to see both the placement of these cabinets and the relative size of the two fridge units and drawers.
IMG-8176And these two freezer drawers.  You can see how far back this space extends under the side decks and we are taking maximum advantage of this voluminous area on both sides of the SuperSalon.  You’ll see more examples in the coming weeks as those cabinets go in.
WhatsApp Image 2019-11-02 at 8.28.59 PM (16)The cabinetmakers amongst you will appreciate this sectional shot of the back edge on one of the walls of the fridge cabinet showing how the exposed edges are all built with solid Rosewood for both longevity and nicely radiused corners throughout.  The marine plywood you see is that new sustainable and very light weight Poplar based product that is working out eXtremely well to dramatically reduce the weight of all the cabinetry and provide a super stable substrate for all the cabinets.

IMG-8173Standing with your back against the Fridge cabinets and looking across to the Starboard side we see that the dining settee is now all fitted in place.  Those two doors in the seat back provide access to that voluminous area under this side’s decks.
IMG-8175Standing forward near the Main Helm station and looking aft this shot provides a sense of scale and location for the dining settee relative to the Galley.
IMG-8178Not all of the action and progress is happening in the SuperSalon as Ömer and Okan continue to work on the cabinetry down in the Port side of the Guest Cabin area.

Okan is test fitting the tall cabinet as you do down the stairs to my Office area.  This and the cabinet that will soon fill the space to the right will be home to the Aft electrical distribution panel, circuit beakers, etc..
IMG-8179With that tall cabinet out of the way you get a better shot of the generous amount of “clean workbench” area I will have in this Office that flanks the corridor leading to the main Workshop and Engine room.  You can see this WT doorframe at the very top of this photo behind Ömer’s back.
WhatsApp Image 2019-11-02 at 8.28.27 PMNever too many drawers and storage on a workbench or office right?  Plus there is another whole set up above.  The large opening below the center of the desktop provides space for a swivel out seat when I’m working here.

ALUMINIUM WORKS:


Last but never least for this week’s Progress Update let’s see what Uğur and Nihat have been up to with several aluminium projects onboard.

FAES2225Nihat made quick work of fabricating and then mounting the circular chain locker.
GTMU5923Uğur laid down a nice MIG weld inside and outside the seam.
ETWW0201They welded in the slightly dished towards the center (for drainage)  bottom plate and the Chain Bin was ready to head to its new home in the Forepeak.

Could almost be mistaken for a work of art don’t you think?
IMG-8184Nihat and Uğur made a series of brackets to attach the Chain Bin to the frames in the Forepeak,
IMG-8183Leaving plenty of space for me to be able to climb in there to clean things out in the future.
IMG-8181Looking underneath shows the solid framing to support the significant weight of 100-150m/330-500ft of 13mm/ 1/2” Schedule 4 chain.

The Chain Bin is completely self draining and that pipe exiting the center of the bottom will lead over to the exiting Sea Chest on the left.

DXNL0068Another new project involved these disks of aluminium and rubber.  Can you guess what these are for?
AAJO0520Getting any warmer with this upside down view?
95BA4FFD-9333-4B94-B4D7-70F973766720How about if I let Yigit show you the completed prototype?
34235c67-ea3d-4dd9-a18c-4fb118085ffdCorrect!  These are the adjustable lids for every circular vent penetration in the deck.  XPM boats are self righting and so all sources of water entry must be able to be shut off either manually or automatically. 
d4940d82-e0d6-4dbd-b6fb-abe65b709f97Most of these adjustable vent lids are located inside the Dorade Boxes on the Foredeck which you can see in this render.  The flexible cowls can be rotated 360 degrees and they catch any breeze and direct that fresh air down into the Dorade Box area below and any water that might come in drains out through slots all along the bottom edge of the Dorade Box and the deck.
321e7f31-91ad-4d51-89a9-74062b1b1e0bThe fresh air flows down into the interior through the Vent pipe when these adjustable lids are well up above the top of the pipe and in almost all situations this ensures great ventilation in almost any weather or sea conditions as the water is kept out.  However if conditions were really severe or for any other reason you wanted to close off these vents you just reach up from inside the boat and turn the threaded rod to bring the lids down and sealed tight against the top of the vent pipe. 

Another good example of the KISS approach we take wherever possible.
WhatsApp Image 2019-11-02 at 8.28.09 PM (2)Uğur, Okan and Nihat were also busy finishing the Paravane A-Frame booms so they erected some scaffolding to get up to the top of the 7m long Paravane booms to fit and weld the hinge assemblies.
WhatsApp Image 2019-11-02 at 8.28.09 PM (6)This is the hinge half at the end of the angled pipe of the A-Frame assembly which
WhatsApp Image 2019-11-02 at 8.28.09 PM (8)…… mates with this swivel that attaches to the beefy Rub Rails.
IMG_20191120_121849In the midst of all this they also found time to complete the building of the rudder which also now looks to me like artwork as it gleams in the sunlight streaming into the shipyard.
062cb647-740f-494c-9bc9-cd9f2270dcccPrior to being assembled and welded the Rudder Post spent some time in the machine shop having the hole for the Emergency Steering Tiller machined through the top and
726049cf-64ca-4078-8ae1-e7ffe73b3837…. the keyway slot milled out for the Tiller Arm to attach to once mounted in the boat.
IMG_20191120_121901The Rudder Blade still needs some finish work on the welds and then the whole blade assembly will be primed, faired and sanded very smooth prior to being eventually covered with foul release paint along with all the other parts of the hull below the Water Line.  For now though it is all ready to be fitted into the hull with its pair of self aligning bearings.

Whew!  I’m tired just writing about all that work. 

Again my apologies for keeping you all waiting and I’ll now go write up the Weekly Progress for this past week so that you are all caught up with the work of Team Möbius.

Our time away visiting friends and family and getting in some much needed Gramma and Grampa time was priceless and we are also happy to be back here and bear down on getting Möbius ready for Launch as soon as we can make that happen.

Thanks for choosing to spend some of your time joining us on this adventure and PLEASE do add any and all comments and questions in the “Join the Discussion” box below.

See you again next week.

-Wayne

PS.  Special thanks to Yigit and Uğur for taking most of these pictures for me while I was away.  Thanks guys!





Steering towards Launching: Weekly XPM78-01 Progress Update–Oct. 21-25, 2019

Steering towards Launching: Weekly XPM78-01 Progress Update–Oct. 21-25, 2019

Well, it is almost Sunday midnight here in Antalya and I’m just getting started on this Weekly Update post after a VERY busy week at Naval Yachts as we all ramp up towards that tiny light at the end of the tunnel known as Launching the first XPM78 aka Möbius.  My apologies in advance then if this week’s update appears a bit rushed but I wanted to be sure to get it posted before I fly out on Tuesday to finally rejoin my Beautiful Bride Christine in Ft. Lauderdale where we’ll be attending FLIBS, the Fort Lauderdale International Boat Show along with Baris and Dincer, the owners of Naval Yachts and most important of all being there for our grandson Liam’s 4th birthday on Oct. 30th.

Without any further ado let’s dive in for a quick swim through all the various jobs that Team Möbius were busy with this past week.

ALUMINIUM TEAM:

IMG_20191021_143749Starting with the always busy Dynamic Duo Uğur and Nihat, our tireless Aluminium team, they finished up the Bow Mast with the addition of the four connectors to the Bow Pulpit railings.
IMG_20191021_143734These ensure that the Bow Mast is well supported and rigid as it can take the brunt of strong winds and waves and we want to be sure that all those antennae, lights and other components mounted on top of this Mast are well supported.
IMG_20191021_143727There is a support above and below the hinge and the are bolted to the Bow Pulpit with these flanges so that the Mast can be folded down when we leave the boat for extended times in areas during cyclone season as well as making it easier to work on the lights and antennae atop the Mast.

The supports and hinges are now all roughed in and will be cleaned up later along with the rest of the Bow Pulpit, decks, etc..
IMG_20191024_171811With the Bow looked after they moved aft to install the hefty hinge plates for the Port side Paravane A-Frames. 
IMG_20191025_094638After marking them out and making sure they matched the ones on the Starboard side, Uğur used the plasma cutter to make quick work out of putting the rectangular slots for each hinge arm to go through the top and bottom of the 10mm/ 3/8” thick Rub Rails.
IMG_20191025_094621The 50mm/2” thick Hinge arm can then be inserted into this slot and tacked in place ready to be welded top and bottom to the Rub Rails.
IMG_20191025_122149The other half of the hinge has been tacked together and is test fitted to the bottom hinge arm to check for alignment prior to fitting the mating aluminium pipes of the A-Frame itself.
IMG_20191025_122159The space on either end of the top toggles makes it easier to install the large 7m/23ft tall A-Frames whenever we have them removed and then insert AL disks that are machined to fill up the space on either side for a nice sliding fit.
Milling rudder post 1Over in the Machine Shop they have the 130mm/5” diameter aluminium rudder post set up in the milling machine to cut the tapered sides where it sits inside the tapered profile of the rudder blade.
IMG_20191024_092907Yigit (left), Uğur (middle), Okan (Ugur’s younger brother) and I spent some time fitting the rudder post into the blade and working out the details for welding these components prior to putting on the outer skin on each side.
IMG_20191024_092918You can see how the rudder post fits into the internal frames and how it tapers from top to bottom.
IMG_20191024_150220These two shots will give you a sense of the size and shapes of these two parts of the Rudder assembly.
IMG_20191024_150235Steering is easily THE most important system on these boats so as you can see we go to eXtreme lengths to make sure the Rudder has an eXtremely high SWAN factor so we can “Sleep Well At Night” knowing it will steer us out of any conditions without breaking a sweat.

GUEST CABIN CABINETRY:

IMG_20191021_143946Omer is a one man army as he marches through building all the cabinetry for the Aft Guest Cabin area.  You may recall their little “Wayne’s Surprise” from last week’s Update and here is a closeup of these two clever shelves which mount on the back wall of the Pullman Berth.
IMG_20191022_111326Here is the lower of these two handy mini shelves which anyone sleeping up here can put things like your watch, alarm clock, pens, books, etc. before they tuck in for a blissful night’s sleep.

You can also see the outer frame for the fold down mattress in this shot as they test fit the Pullman Berth cabinet into the rest of the furniture in this Aft Cabin.
IMG_20191021_144332The rear panel of the Pullman cabinet is removable as you see here to allow for quick and easy access to the wire trays and plumbing behind if it is ever needed. 
We make sure that ALL such infrastructure is either left exposed in areas like the Basement, Workshop and Forepeak and that any cabinetry which covers these is easily removable.  Being the ones who have to do ALL the maintenance on this boat we go to great lengths to make it a joy to work on rather than a chore as is the case with most boats.


IMG_20191022_111339Stepping back gives you a view of how all these components fit together with Christine’s Office desk with overhead bookshelves on the far right, pull out sofa bed on the bottom, Library shelves on the upper left and the Pullman upper center.
Corridor Workbench

Just outside the Guest Cabin & Office is the Corridor at the bottom of the stairs down from the SuperSalon and the Head/Toilet is behind the door on the right.  The workbench up against the side of the Port/Left hull on the left here will be my little office and clean area for working on things like electronics, 3D printing and such that is best done here rather than in the Workshop.
IMG_20191024_121713  Standing up at the top of the stairs looking aft you can see how this Corridor connects to the WT door leading into the Workshop.  The area to the left of that door is starting to be roughed in for the Guest Shower that will go here.
IMG_20191022_111445Hakan (left) and Omer are laying out the exact location for the wall grid that will go up along the side of the hull on the right.
IMG_20191024_121718That hull is a busy area with all the plumbing and wiring runs going through here so the grids ensure that the wall panels are spaced well away from this and provide a super sturdy foundation for the removable wall panels to snap into using FastMount clips.  More on those details to come as this area is installed.

GALLEY CABINETRY:

IMG_20191024_141120Upstairs in the Galley, …………………. Hey!  Wait a minute.  What do we have in that far cabinet??
IMG_20191024_141127Aha!!  Those darn CE inspectors show up when and where you least expect it!


Actually this is young George who is here at Naval Yachts for a week with his parents who are about to become the proud new owners of XPM78-02 and so George wasted no time checking out the quality of the workmanship so he can assist the crew when they start building HIS new boat.

IMG_20191024_142801His beautiful and +6ft tall Mom Uschi got his quick assessment which was two thumbs up so all is going VERY well with the build.

IMG_20191024_093719

Meanwhile, over in the Cabinetry shop, Omur and Selim are busier than ever building the next set of cabinetry for the twin fridge and freezers.  Omur is a true Master at creating patterns with the grain that are works of art and when doing this with veneer he carefully cuts each piece, tapes the razor cut joints on the exterior surfaces and then lays these onto the lightweight marine plywood and puts them in the heated veneer press.
IMG_20191025_122512Working with these gorgeous Rosewood veneers requires tremendous craftsmanship and is all done by hand with these simple tools.
IMG_20191025_122704Each piece of veneer is carefully chosen to have just the right grain pattern for the size of the panel it will form and then cut to rough size with a razor sharp knife.
IMG_20191025_122618Omur prepares a batch of panels for the veneer press and carefully stacks all the pieces in order to keep their orientation straight.  These are two end panels for the cabinet that will hold the pair of 130L fridges and are now ready to head over to the veneer press.
IMG_20191025_122648On the next workbench over there are these carefully stacked pieces that will soon emerge as some of the 22 different sized drawers in the Galley.

EXCITING NEW THINGS SEEN IN PASSING:

IMG_20191024_165455Last bit of excitement this week was seeing this.
IMG_20191024_165516We can’t have a Weekly Progress Update without a quiz so any guess what Yigit is doing here?
IMG_20191024_165525Probably an easy one for many of you, this is a test run on the groves which are cut into the 50mm/2” thick rigid foam board on all the floors where the red PEX tubing which carries the hot water for the in-floor heating.  We’ll show you this when the installation begins onboard Möbius but you can see how this works. 
Once all the PEX is nestled into these grooves and sitting just below the top surface of the insulation foam, a layer of 10mm / 3/8” marine plywood goes down and then the finished flooring, which will be some very cool new vinyl planking, is set on top.  Much more on all that in the coming weeks.


IMG_20191024_141339More exciting new things seen in passing this past week was watching Cihan (left) and Yigit bring this 200L Black Water holding tank system aboard and down into the Basement.  There are two of these Black Water holding tank systems, this one going into the Basement is for the Guest Head and the other one goes into the Forepeak for the Head in the Master Cabin.  You can now see what that hatch in the floor of the SuperSalon is as large as it is!
IMG_20191026_094928Last but DEFINATELY not least for the excitement this week, we finally have all the interior materials chosen and what you’re seeing here is the three colours of leather that will go on the wall panels, some of the drawer and door fronts and the ceiling panels.


The stone you may recall from several months ago when we found this fabulous slab of rare green/gold marble and it now has these three colours of leather to compliment it.

Top white leather will go on the ceiling panels, the middle Grey/Green will go on the walls and the bottom Black will go on the ceiling above the Main Helm area to further reduce any reflections and glare on the windows when on night passages.

OK, it is WAY past my bedtime now and I have another super busy day ahead of me tomorrow, my last day here before I fly to Florida, so I’ll sign off for now right after thanking you for making it through another weekly update on the progress of Team Möbius.  Please do add your comments and questions in the “Join the Discussion” box below and I’ll be back next week to show you what has happened while I’m away.
