INFECTED with PROGRESS: XPM78-01 Möbius Progress Update March 30-April 03, 2020

I am VERY pleased to be able to report that everyone on Team Möbius including Christine and myself are all doing well and managing to stay safe, fit and healthy.  As per the title the only thing we are “infected” with is enthusiasm and progress.  We certainly hope this will continue although the numbers of cases and deaths in Turkey while still relatively low compared to most other countries, have continued to climb. There is a general “stay home, stay healthy” recommendation for all and requirement for some, face masks are now required in grocery stores and the like and more and more cities, including Antalya where we are, have been closed for travel in or out.  Hopefully the escalation of these defensive restrictions and regulations which will outpace the virus and be effective in flattening the curves.

On the good news front, I was delighted to end my two weeks of self isolation after our trip to London last month and rejoin the rest of Team Möbius back at Naval Yachts on Monday.  I have made several changes though such as moving my office into my Workshop so that I can now spend 98% of my time still quite isolated and well distanced and I now only go aboard Möbius when everyone else is off the boat on their tea, coffee and lunch breaks.  This has been working well and I have been able to get back to photographing all the progress so let’s jump right in and show you what’s been happening this past week.

I think I will organise this weekly update by starting at the front of the boat and working my way aft so let’s go up to the Bow.


IMG_20200330_130620If you read last week’s Update you recall seeing that Uğur and Nihat were getting ready to mount the Maxwell VWC 4000 windlass and this is the final location they have marked out.  The long line is the centerline of the anchor chain as it comes back off the shank of the 115 kg/242 lb Rocna anchor though that side mounted bow roller chute.  The circle is the main body of the windlass gypsy and capstan and the small holes are where the studs from the Windlass body go down through the 15mm/ 5/8” AL deck plate and are secured from below to the 24V motor and gear assembly.
IMG_20200330_130711Down inside the Forepeak looking up at the spot where the Windlass will mount you can see the extensive 10mm / 3/8” stringers underneath that 15mm deck plate.
IMG_20200330_130656Some of you were asking about our Chain Bin so here is a better shot of that.  Having a relatively small and round area for the chain to pile up in helps keep the chain from “castling” very much and falling over on top of itself which prevents the chain from becoming tangled and difficult to put out.

The Chain Bin itself is about 70cm / 28” in diameter and about 1.5m / 60” tall with a drain in the bottom which exits out through the side of the hull just above the waterline.
IMG_20200330_130702 I had put in a similar drain in the chain locker of our previous boat and it worked extremely well to automatically drain any water and muck right back out and a good rinse from the washdown hose every once in awhile kept it clean and pretty much odorless.

There will also be a clear plastic “gaiter” fastened around the top of the Chain Bin and the bottom of the deck to contain any water and muck that might want to fly off the chain and mess up the Forepeak.

IMG_20200330_130834Just aft of the Chain Bin I can show you this detail of these two built in SS Quick Connect fittings on the aft end of the Anchor Deck.  One connects to the Fresh Water wash down pump and the other to its Salt Water sister which makes cleaning up the chain as it comes aboard very easy as well as keeping the whole Foredeck nice and clean.

The White PVC pipe is the Compressed Air line that runs the entire length of the boat for pneumatic tools, blowing things up and cleaning.  The larger clear hose is one of the vent lines for the large water tanks below the Master Cabin sole.

IMG_20200330_154631Uğur and Nihat were also able to finish up one of the two Fresh Air manifolds that go up in the ceiling of the SuperSalon.  This is the forwardmost one that sits overtop of the Main Helm and then a second one is about 2 meters aft of that in the center of the SuperSalon.
IMG_20200330_154645Looking on the other side these 5 vent tubes set well above the bottom of this air plenum or manifold and have manually activated vent lids which can be pulled down tight to seal off each vent entirely if things get really rough and we want to shut off the air flow entirely and keep any errant water out.
IMG_20200330_154635Looking up inside one of the vents you can see the simple cross knob that you can easily turn by hand to move the lid with its rubber seal up/down as needed.  Keep it Safe and Simple or KISS it right?


IMG_20200330_124431Moving Aft into the Master Cabin, Selim and Şevki have been continuing installing the ceiling grid and snap in panels.  This is standing beside the Shower on the Right looking towards the Aft Port/Left corner of the Master Cabin.

Bed on the far Left with all its drawers underneath and the dropped ceiling above. 
IMG_20200330_124444Some of the leather covered snap in wall panels on the Right have been remove while Cihan is putting in the black ducting behind the wall grid for the AirCon/Hot Air to flow from the Air Handler underneath inside the narrow floor you can see in the photo above up to …………………..
IMG_20200330_124439…….. this beautiful Rosewood vented air box up on the ceiling.
Main Cab black roofTurning a bit to Starboard you can see the stairs leading up to the SuperSalon are ready for their treads to go in and Christine’s Bosch Washing machine, with WiFi no less, is setting atop the bed frame ready to be installed in its forward cabinet soon.

For those wondering, they have painted the ceiling grid Black to create a nice contrast to the narrow space between each of the White leather covered ceiling panels when they are snapped into their FastMount fittings in each of those small holes.
Main Cab black roof 2Spinning around 180 to look forward you can see they have done the same to the rest of the ceiling grid up front. 

Master Shower in the Left foreground with its adjoining Head/Bathroom behind.
IMG_20200330_125145The rough ceiling panels have now been fitted and snapped into place in that forwardmost area with the Bathroom/Head on the Left, Vanity sink area in the center and the Wardrobe cabinetry along the wall on the Right.  The washing machine will be installed in one of these upper cabinets.
IMG_20200330_125151Zooming in on this nice bit of detail where three of the ceiling panels meet up on the small corner around the Bureau of Drawers that is on the far Right.


IMG_20200330_124520The Master Shower/Bathroom continues to get fully glassed in.Shower is in the Left foreground and the corner walls here will be etched glass.  Shower seat on the bottom Left with the Bathroom countertop extending all the way to the far wall with the toilet mounted on the raised floor platform to the Right. 

There will be a clear glass half wall inserted in that slot between the Shower seat and the Sink cabinet on the Right which will separate these two compartments and keep the Bathroom dry.
IMG_20200330_124605The two upper “Medicine cabinets” as I grew up calling them have been clamped in place ready to be glassed in.

There are removable backs inside these cabinets to provide easy access to the plumbing behind the wall.

The hole in the ceiling is where fresh air flows in from the Dorade Vent above and you can just see the corner of the large hatch above the Shower and part of the Bathroom to bring in more fresh air and LOTS of natural light.

IMG_20200330_124927VacuFlush toilet mounts to this black flange on this raised platform and the rectangle in front is to provide access to the water tank access port underneath. 

The Shower and Head will each have lift out Teak covered floor plates so all the water drains off their edges into the seamless floor pans below and out the drains into the Gray Water pumps.
IMG_20200330_124615Just outside the Head/Bathroom door frame on the Left is the Vanity Sink with its own upper cabinet on the wall and another big hatch above.


IMG_20200330_124131Omur and Selim made lots of progress in the SuperSalon and Main Helm areas this past week.  Looking towards the Bow and down the spiraled stairs you can see all the drawers on the side of the Bed in the Master Cabin below.

Arm of the Settee in the bottom of this photo and Main Helm above.
IMG_20200330_123815_MPStanding in the opposite corner at the bottom of the other stairs coming down from the Aft Deck gives a better sense of the overall layout of the Galley on the Right, Helm up front and double Fridges cabinet on the Left.

Hatch into the Basement in the center.
IMG_20200330_123913A good glimpse at some of the craftsmanship details of this Port/Left corner of the Helm area.  Our ubiquitous BHL Blue Horizon Line continues winding its way through the boat.
IMG_20200330_123933Peering down inside this triangular cupboard gives you an idea of just how cavernous and deep this space is thanks to the dropped ceiling overtop the head of the Master Bed below.  There will be a Black leather covered lift up triangular door on top here to reduce any glare in the negatively raked window glass at night.
IMG_20200330_123936This center area of the Helm will have a sloped dashboard panel with two 19” touchscreen daylight readable monitors set in behind it just in front of this center window.
IMG_20200330_123942On the Right side of the center Helm Chair this sloped wall provides more area for Helm controls and switches.

Forward electrical panel inside this area and Hilmi has started to fasten in some of the many cables coming up from the Basement.  Most of our 24V circuit breakers and some electric system monitoring gauges will be inside.
IMG_20200330_124125The far Starboard/Right side of the Helm has a matching triangular storage area.  This one isn’t quite as deep to provide plenty of headroom through the doorway below.
IMG_20200401_125932Can you guess what Omur and Selim are making up here?

Hint; they also go into the SuperSalon area hence my including them here.
IMG_20200402_154228Full marks if you were able to guess that these are the corner brackets to make the transition between the top of the window frames to the ceiling.
IMG_20200403_130149_MPThese will go all the way around the whole perimeter of the SuperSalon windows.
IMG_20200402_124732One detail some of you fellow DIY and Makers might appreciate is this thin phenolic based layer they laminate to the marine plywood surfaces to provide a perfectly smooth surface for paint and leather to be applied. 
IMG_20200402_124735Quick and easy to laminate onto the plywood surfaces and then trim the edges flush with a router bit.  Glue and paint stick tenaciously to this material without any raising of the grain of the plywood or need for multiple coats to fill the porous wood below.
IMG_20200331_125138Another detail I received several questions about is this thin acrylic sheet I have in my dirty little fingers here.  It starts out as a sheet of thin 2-3mm clear acrylic which we then had our aquamarine swirl photo printed onto the underside surface. 
IMG_20200331_125127Once back from the printer these are easily sawn into strips for the Blue Horizon Line which you can see stacked up in the background.

IMG_20200330_125725A heat gun softens the strips where they need to wrap around radiused corners and are easily glued into the recesses behind the Rosewood hand holds and other edges such as these winding around the Settee bottoms.


IMG_20200330_153938More of our 360 degrees of BHL snaking its way around the Galley cabinets just under what will soon be the aquamarine granite countertops.
IMG_20200330_130025Galley Garages are back from the Finishing Shop and being fit in place.
IMG_20200330_125748Foundation framing being completed so that the rigid foam floors can be put in place and the grooves for the In-Floor heating PEX tubing can be cut.
IMG_20200403_162504Once he had all the last of the floor frames adhered to the AL plates Selim got to work cutting and fitting all the rigid foam insulation.
IMG_20200403_182137He then cuts and fits the 10mm / 3/8” marine plywood flooring.
IMG_20200403_182147These are just dry fit for now as they need to come up for the installation of the In-Floor heating PEX tubing before they are finally glued and screwed to the frames.  The finish floor will be strips of some new “click locked” vinyl flooring that is now used in airports, shopping malls and other high traffic applications. 


Guest ceiling panel 3Down below in the Guest Cabin, Omer and Muhammed have been hard at work putting in the removable ceiling panels.
IMG_20200330_153823Same system as we saw earlier in the Master Cabin with the Black ceiling grid to provide some depth and contrast in the space between the White leather covered ceiling panels when they are snapped into place like these three overtop the bookshelves hiding behind their protective cardboard coverings.
IMG_20200402_124134_MPAnd these ones overtop the Pullman Berth and ….
IMG_20200401_101706…… Christine’s Office Desk with its own Bookshelves above.

Rosewood box on the Left of her desk provides some of the support for the Pullman when it is pulled down as well as being ………………
IMG_20200330_123708……………………… a removable cover giving access to the Air Handler inside that corner cupboard.
IMG_20200403_101410They have also been busy installing the sink cabinet and surround in the Guest Head with more of the BHL of course!
IMG_20200403_182007Ro$ewood countertop being attached.  Sink will be atop the counter on the far Right with storage cupboard below.
IMG_20200403_181929On the other side of the Bathroom wall Omer and Muhammed have been started work on the BHL and handrail leading up the stairs.

Boat Office (aka mine!) on the Left.
IMG_20200403_162723Carefully fitting and gluing the BHL strips into place.


IMG_20200403_182043On the opposite side of the photo above, behind Omer’s back we see some of Hilmi’s handiwork putting in the nautical miles of cables and wires. 

This is the Aft Electrical Panel which will be home to most of our AC DIN rail circuit breakers as well as some more 12 and 24V equipment.
IMG_20200330_124013This is the Forward Electrical Panel we say earlier on the Right side of the Main Helm which holds most of our 24V circuit breakers, switches and gauges.
IMG_20200330_124017As you can see Hilmi has most of these cables coming up from the Basement, zip tied to the bottom for strain relief and ready for connecting all these wires to their respective circuit breakers, switches, controllers and gauges.
IMG_20200330_125331Down in the Basement he has also been hard a work putting in more of the N2K network and Maretron monitoring system.
IMG_20200331_125546Another AL panel in the diagonally opposite corner of the Basement with more Maretron black boxes and one of the blue multi-port boxes on the N2K Backbone.
IMG_20200330_125629Looking up, we can see that the wire trays are starting to fill up with all the different cables and wires going in and out of the Basement which is purpose built to be Grand Central Station for all these systems.


IMG_20200330_123217Back in the Workshop, Cihan’s plumbing handiwork is evident with examples such as this set of ball valves for the sea water going in/out of the Sea Chests in the Engine Room.  These four are the sea water supply and return lines for the Delfin Watermaker’s low pressure Feed Pump and the Webasto Chiller’s circulation pump.
IMG_20200330_123214Above these ball valves are more lines for Domestic Hot & Cold Water, Chiller water and bilge pumps.
IMG_20200330_123312Looking forward alongside the Engine Room walls on the Left and the Day Tank in the upper Left corner you can start to see just how much work Cihan has been doing putting in all these hoses and ball valve manifolds for everything from fresh and salt water, Bilge and Gray water lines, fuel lines and compressed air.
IMG_20200330_123338Here for example are some of the many hoses going in/out of the Engine Room on the Left with the deep sump of the Day Tank above with its blue handled ball valve for easily draining off any water and dirt that collect there.
IMG_20200330_123400Up on top of the Day Tank Cihan is starting to plumb in the fuel lines to their respective ball valves across the top.


IMG_20200402_171748One of the more exciting new developments this past week was Uğur and Nihat’s work putting in the framework for this very cool composite grid that Yigit found for us.  This is normally used for walkways in high traffic industrial settings and marinas for example. 
IMG_20200402_171752It is about 35mm / 1.4” thick and comes in sheets about 1m x 4m long.  Easily cut with a circular saw or hand tools and impervious to everything from fuel to acid so should work really well for flooring in the Workshop, Engine Room and Forepeak.
IMG_20200402_154119So Uğur and Nihat got busy putting in a whole framework of L-bar for this flooring grid to attach to.  This is the floor alongside the Port/Left side of the Workshop/Engine Room with the WT door into the Guest Cabin/Office area at the far end.
IMG_20200403_181824_MPOn the Stbd/Right side Uğur tacks in the L-bar frames around those Sea Water ball valves we saw earlier.
IMG_20200403_101319Doesn’t take him long to get this all tacked up and all leveled as it extends all the way forward to under the Day Tank.
Workshop floor framingUsing this system we are able to keep the Workshop floor all on the same level by framing around the Prop Tunnel as you can see here.  There is a center workbench directly overtop the bulge of the Prop Tunnel with storage below so the large thick arched frame member does not impede walking around the aft end of the Workshop.


IMG_20200331_153819Nihat and Uğur were in top form this past week as they also put in this very special milestone; the installation of the Aft window frames and ……
IMG_20200331_153827……. Aft Entrance door from the Aft Deck into the SuperSalon.

These have been purposefully left out up to now to make it easier to bring all the cabinetry and large equipment in/out of the interior but with all that now done these last bits of the aluminium framing can go in.

IMG_20200331_153849If you look closely at the top of both vertical door frames above you can see these oval cut outs which enable us to use them as well protected chases for wires and cables running from up in the SkyBridge and down into the SuperSalon and Basement.
IMG_20200331_153902On the outside on the Aft Deck you can see how the window frames provide the same recesses for the 28mm / 1.1” tempered glass windows.
IMG_20200402_124216Once the welding was done and cool, Nihat started putting in the EPDM insulation on these new AL surfaces.
IMG_20200401_154557They were also able to cut these large holes in the Upper Aft corners of the SuperSalon which connect into the Upper Wing Vent Boxes that extend aft on both side of the Pilot House. 
IMG_20200401_154604There will be a large axial extraction fan inside each of these Vent boxes to pull air out of the Galley (shown here) and SuperSalon areas and keep a good flow of fresh air throughout this large living space.


But Wait!  There’s still more from the Dynamic Duo of Uğur and Nihat

IMG_20200330_130310Clearly “infected” with enthusiasm Nihat and Uğur also worked on lots of details on the two large Vent Boxes you’ve been seeing take place over the past month. 

This is one of the Extraction Fan boxes which Yigit cleverly designed.
IMG_20200330_130333A large axial fan will be mounted inside this box pushing air out the top 5 slots and the bottom is sloped so that any water that gets in here can quickly drain out those bottom slots.
IMG_20200330_131826Here is another extraction fan boxes of Yiğit’s same design and this one mounts on the Lower Wing Vent Box just outside the Aft Entrance Door. 
IMG_20200330_131819Inside, you can see 2 of the round air ducts coming up out of the Corridor and Guest head below with the same shut off lids we saw at the beginning of this post so that these vents can be completely closed and WT if things get really nasty outside.
IMG_20200330_130149Also in the Vent Boxes and something I received several questions about was these Mist Eliminators so I wanted to provide some more examples and explanation.
IMG_20200330_130343These flush mount on the inboard sides of the Vent Boxes and their specially designed set of fins inside cause the incoming salty air to give up most of its moisture and also break up any full hits of water that might splash up this high.
IMG_20200330_130139If you look closely inside (click to enlarge any photo) you can see the fin shapes and also the drain in the bottom that will have a drain hose attached to take the water back out to the deck.
IMG_20200330_130155Looking down deeper into the Port supply air Vent Box you can see the entryway duct heading down …..
IMG_20200330_123446_MP………….. into the Engine Room through this long AL duct which brings the cool dry outside air down to the floor of the ER to help maximize the natural flow of air as it warms and rises up to exit out the extraction vent up on the ceiling of the opposite side of the ER.


IMG_20200330_132103Finishing the tour at the very Aft end of the boat to show you this last bit of aluminium work Uğur and Nihat completed this week with the final welding of the prop shaft removal tunnel in the rudder.  A small but highly valued feature that makes it possible to remove the Prop Shaft without having to also remove the Rudder which is not a quick or easy thing to do.  Nice work boys!

Mr. Geeee!

Spending almost all my self imposed “shelter in place” time at the shipyard in my reorganised Workshop, one advantage is that I am now able to devote more time to Mr. Gee as we affectionately call our Gardner 6LXB main engine.

IMG_20200401_130247In previous weeks I had sandblasted, scrubbed, pressure washed and primed all the main aluminium castings and this week I was able to apply the top coats. 

He has cleaned up very nicely for a 50 year old guy don’t you think?

Brief Tech Talk:

IMG_20200401_130311[15]For those interested, I’m using a special high temp silicone based paint and the primer is rated for up to 600C/1112F and the top coat here is rated at 300C/572F which is way beyond any temps Mr. Gee should experience.  The topcoat you see going on here, is basically aluminium dust mixed into clear silicone.  Works great and looks like brand new aluminium which was my goal. 
IMG_20200401_130339I was originally going to leave all these castings in their natural “raw” sandblasted aluminium state but the nature of cast aluminium is that it is quite rough and porous which tends to retain oil and dirt.  So I decided to paint all these surfaces not only because I wanted Mr. Gee to look good, I also like to have light coloured and very smooth surfaces on my engines so that they are easy to keep clean and more importantly easy to spot any leaks right away.

I found that even when the aluminium top coats were fully cured, when you rubbed these surfaces with your fingers or a clean cloth, some of  the aluminium dust particles suspended in the silicone would come rub off, so I put on two coats of clear to create a smooth and impervious final finish.

LOTS of work as you might imagine, but well worth it and I am eXtremely happy with the end result both now and over the next few decades of Mr. Gee’s next life.

IMG_20200403_163135Various cast AL covers which bolt to the Crankcase also received their fresh new aluminium and clear coats. 
IMG_20200401_130318_MPThis first half of the flywheel housing will soon be bolted to the end of the crankcase above and then ……
IMG_20200401_130332……. has its other half here bolted on to complete the housing with the monstrous flywheel fully enclosed inside.

The SAE1 bolt pattern on this housing mates with the SAE1 pattern on the Nogva CPP Servo Gearbox to create a single solid propulsion unit that drives the 65mm/2.6” diameter Nogva prop shaft.
IMG_20200401_130303This is the “tiny” little cast aluminium oil sump/pan which I’d estimate weighs over 22kg / 50lbs by itself.  Ask me how I know!  It holds 27 Litres of oil.

All surfaces are fully finned to increase the cooling of the engine oil and then there is an additional dedicated engine oil heat exchanger that was the next focus of my attention this week.
IMG_20200402_182240This is the solid bronze engine oil cooler which runs along the side of the crankcase..  It is a heat exchanger style cooler with sea water pumped into it through the bronze 90 degree elbow in the Right foreground and out the arched pipe you can see on the far end and in the photo below.

Engine oil is pumped into the flanged fitting in the Left foreground ………
 IMG_20200402_182257………. which then exits out a similar fitting on the far end which has an external copper pipe that carries the cooled oil back into the oil sump.

There is a dedicated gear driven oil pump to move the oil through this cooler.

Keeping the engine oil at a consistent temperature is one of the keys to the eXtremely high efficiency these Gardner engines have, hence this dedicated oil cooler.
IMG_20200402_185409Didn’t take me too long to disassemble the oil cooler and you can now see how it works.  The hot engine oil flows through that cool looking crimped bronze tube in the middle here and the cool sea water is pumped through the two part square cast bronze tubes on either side.  Classic Gardner over engineering that I never get over. 

IMG_20200402_185424Not seen here, but there is a replaceable long thin strip of zinc anode that runs inside the full length of the cooler so that it rather erodes rather than the brass or bronze parts due to the natural galvanic corrosion that is a function of dissimilar metals immersed in electrolytic sea water.

I brought a new one back from our London trip last month when we visited Gardner Marine Diesels in Kent

One of Christine’s many birthday presents! Smile
IMG_20200402_184831This close up of one end lets you see how the sea water flows through the outer square area surrounding the round crimped brass tube in the middle which has the hot oil flowing through it.


IMG_20200402_154422Last but definately not least for this past week was this newest arrival.

Can you guess what’s inside?
While you ponder that, I want to be sure to give an eXtremely big XPM Möbius shoutout to the people who were so great to work with to make this happen:

Thanks to Rob Westermann who runs Artnautica EU over in Hindeloopen Netherlands along with with our XPM designer Dennis Harjamaa at Artnautica HQ over in Auckland New Zealand.  Rob has become a good friend of Christine and mine as well as Naval Yachts and it was only thanks to his extensive network within the marine industry and especially in the Netherlands that we were able to work out this Goldilocks water heating system with Kabola.  I’ve been a big Kabola fan since first encountering their super efficient diesel water heaters or boilers more than ten years ago so it brings me great joy to finally have this aboard our new home Möbius.

I also want to thank Othni and Roelof at TCN Techno Center Noord the Kabola distributor in Sneek NL who worked with me through all the technical detailing and engineering of our diesel fired hot water system.

And most recently, kudos to Hugo at Clion-Marine Eberca B.V. who was an ace at getting this shipment through to us in these challenging Corona virus times.  Fortunately air freight flights and the global supply chain still seem to be up and running in most parts of the world and I’m hopeful this will continue.  Fortunately we now have pretty much all the equipment we need for the build so shouldn’t need too much more but with boats there is ALWAYS something more you need it seems.

Thanks to all of you!

IMG_20200402_181433So as you might have guessed by now, this week’s New Arrival was our Kabola KB45 EcoLine Combi diesel fired water heater fresh off the plane at Antalya airport from where they are made in the Netherlands! 


These newer Kabola EcoLine models now have all digital controls and thermostat by Siemens and they average about 94% efficiency.  You can hold a white rag over the exhaust outlet and not catch a trace of soot and I’ve seen some of these being opened up for maintenance after 2+ years of steady operation with almost no soot in the burner itself at all.
IMG_20200402_181826We ordered the full Kabola exhaust system which helps to keep the exhaust almost silent when it exits out the hull and very low heat escapes through the double walled heat exchanging exit pipe.

The “Combi” version of these Kabola EcoLine boilers has two independent water circuits; one to help heat the Domestic Hot Water in the central Calorifier aka Hot Water Tank, and the second circuit to heat the interior air in the boat via the Webasto A-Series Air Handlers in each room.  Here is how that all works:

Webasto IsoTemp interior1.  One of the circuits in the Kabola boiler heats fluid circulating through one of the two heat exchanger coils inside the IsoTemp Calorifier (Hot Water tank) which is the source of all the DHW Domestic Hot Water that circulates throughout the boat to supply each sink and shower. 

This cutaway model at the Dusseldorf boat show lets you see inside a single heat exchanger coil model.

Our model of these Webasto Indel IsoTemp Calorifiers has a second heat exchanger coil inside that circulates some of the hot fresh water/antifreeze coolant from the Gardner engine so we get “free hot water” whenever Mr. Gee is running. 

And if you look closely in the cutaway model above, you can see that there is a third heating source in the center which is a traditional 230V electric coil.  Not being connected to shore power we would rarely use this but could prove useful sometimes.

Webasto A-Series BlueCool compact-air-handler-36000-btu-s-wbcl12090152.  The second circuit being heated by the Kabola KB45 boiler heats fluid going to any of the four fluid to air heat exchangers inside each of the Webasto Air Handlers or “Fan Coils”; one in each Cabin and one on each side of the SuperSalon.  When supplied with hot water these heat exchangers or Air Handlers, transfer the heat from the fluid to the air blowing through them and warm up the space this way. 

These are the same Air Handlers double as our Air Conditioners in hot climates simply by having the Chiller feed them chilled water instead of hot.  Single units, dual purposes, which we try to do with as many of our systems as possible.

Of course whenever we are in colder or Polar climates we will most often use our In-Floor heating system which runs through three independent zones; Master Cabin, Guest Cabin and SuperSalon.  The In-Floor heat also comes from the Domestic Hot Water circuit coming out of the Calorifier so we get to capitalize on that super efficient Webasto boiler to keep us nice and toasty no mater how cold it is outside.  The day I was born in Whitehorse in the Canadian Yukon it was minus 53 degrees out so I know what Cold is! 

BTW, at these temperatures you don’t really need to bother with Centigrade/Fahrenheit conversion as –40 C = –40F but if you want to be more precise, –53F = –47C which is more often known as simply k k k k K K K K K K KOLD!!!

OK, that wraps up the latest Möbius World Weekly Progress Update and I hope it helps provide some good reading and distraction for all of you who are similarly practicing some form of isolation as we all try to navigate our way through this most unexpected global storm.  All of us over here hope that all of you out there are finding ways to to keep yourself, your family and friends safe, healthy and happy throughout.





MÖBIUS will be all-PC, and we don’t mean politically correct

MÖBIUS will be all-PC, and we don’t mean politically correct

The first time I sailed across the Pacific was in 1975. This is a much younger me in Nuku Hiva in the Marquesas.

Generous Marquesans gifts

We navigated with a sextant and a chronometer that we kept in a velvet-lined box. Paper charts and pencil. The only pieces of electronics gear on that 44-foot sailboat were a Heathkit home-built digital depth sounder and a battery-operated multi-band short wave receiver. No radio, no refrigeration, and for entertainment, we usually read books by the light of a Coleman lantern.

My, how things have changed in 45 years.

While I’m really glad I got the opportunity to experience those early days of cruising, I have never longed to go back to the “good old days.”  Rather, most of my life I have been an early adopter of technology, from Loran to Sat-Nav, to GPS, to computer navigation, to iPads and navigation apps. So it just seemed right when Wayne was finding himself a bit overwhelmed with the work of ordering equipment and overseeing the build, and not finding enough time to work on our beloved Mr. Gee, that the job I could most likely help out with was in the area of electronics and networking. So I dove in to the deep end of the research pool and quickly found myself over my head. But, hey, I find it really exciting to learn new stuff, and that’s a huge part of what this building Möbius  is all about for us.

Over the next few weeks and months, I hope to write several blog posts covering my journey of learning and decisions we have made about our various networks, from NMEA 2000 to ethernet, to our Victron smart management system of our batteries, chargers and solar panels. Today, I’m going to start with our decision to go all-in on PCs.

Multifunction display chart plotters, or MFD’s have become the standard on most recreational boats. When I met Wayne, he had a single Raymarine E7 chart plotter on Learnativity, the boat we sold before starting this project. He had fitted that boat out 15 years before, upgrading the original electronics. Then he upgraded again many miles later when that plotter failed. Each time, it was rip out the old and stick in new hardware.

Today’s multifunction chart plotters show radar, AIS targets, depth, fish finder graphs, sonar, and night vision cameras. Some interact with the boat’s stereo system, can switch to internet browsing, and even take control of the boat’s drones! They are amazing, but essentially, they are closed black boxes that need to get sent back to the manufacturer for repairs.

As versatile as today’s MFD’s are, there is still much they cannot do. You cannot install any other software on them. At the very least, we knew that we wanted to have a pretty big and complex Maretron monitoring system on the boat, and we would need to run N2K View software. Plus, we wanted a permanent ship’s entertainment system with all our collection of photos, music and video on a Synology NAS hard drive system. We were going to need a ship’s computer anyway.

So then we started to look at the navigation equipment we wanted to use because that would, in part, drive our decision as to the navigation software we would use. Early on, we made the decision to go with Furuno for most of our electronics on the new boat. We started with what radar we wanted and Furuno won on that count, and their customer service is very good, their equipment extremely robust. So initially, we were looking at Furuno MFDs.

But one of the problems we faced was that we wanted lots of screens to see all those different systems all the time at two different helms. And given that we both wear glasses and are not getting any younger, we wanted decent-sized screens. Each MFD chart plotter has a powerful computer inside. These days most manufacturers also sell Black Box chart plotters allowing customers to connect them to their own monitors, but the Furuno TZT2BB while it has two Windows computers inside, only allows two monitors. And the 15” TZT2 MFDs we were looking at started at an MSRP of over $5000.00 each.

In the end the main reasons we decided to forego MFDs and go as a strictly PC boat were:

1. Cost

2. Upgradability

3. Versatility

Another thing we liked about Furuno was the fact that their navigation software that runs on Furuno MFDs is also available from Maxsea Nobeltec for PCs. Today, the program is called TimeZero, and while Furuno licenses the software for their MFDs, we can also run it on a Windows 10 computer. We considered OpenCpn, a free, open-source navigation application, but we read too many posts about people having the application crash, and it only will work with some radars, not all. When we investigated the TimeZero software, we were sold. The interface is beautiful and it works with Furuno radars. TimeZero comes in two version, Navigator and Professional, and while it’s not cheap, we decided to go with the Pro for all the extras, and we bought two licenses for just over $2000.00. Yeah, ouch.

Our first plan was to have our two computers be a permanent ship’s computer and then Wayne’s laptop would stand in for the second. It would give us redundancy, and we could do planning on the laptop.

Then I went on the forums and started to research computers. There is the Trawler Forum, the Cruisers and Sailing Forum, the Facebook Group TimeZero Navigation Software User’s Group, and the Furuno Community Forum. There are also lots of blogs we have mentioned previously as our favorites. I searched and read as much as I could, and of course, there was lots of disagreement.

Some folks are adamant that the ship should have a navigation computer with no other software on it, while others use theirs to navigate AND watch movies and check email, and they’ve been doing it for years.

Some swore by powerful machines, while others were happy to run OpenCPN on Raspberry Pi computers. Some said they would never trust a home-built, hack-job, while others said that nearly everything on their boats was DIY so they could fix it when it died. Some said you could buy a computer, but you’d save lots of money if you built it yourself.

When I talked to a Furuno rep about what specs they would like to see in a computer to best run TZ, I was told, “Our standard currently is an I7 CPU, 8/16 GB ram, gtx1060/1070, and a 250gb solid state HDD.”

In the end, I decided to do a bit of all of it. We will have two ship’s computers – in addition to our laptops. For the skybridge, we will buy a fanless industrial computer that will be kept pure as a ship’s computer and will run only TimeZero and N2K View. On the more powerful one at the main helm, we will not worry about contamination, and we’ll run whatever software we want. It will be our entertainment center as well. And this Apple fangirl decided I would build this Windows 10 box myself. While you can run TZ on older i7 processors, I didn’t want our system to lag while outputting to multiple monitors and running the graphics intensive charting software. So, I decided to spend the money on the 9th generation Intel processor in part because it can support up to 4 monitors, and that is what we have planned for the lower main helm: two 15” monitors at the helm, one 43” monitor to port and a 49” TV to starboard. TimeZero Pro only supports three “workspaces,” but we will want a permanent display for Maretron N2K View.

I really enjoyed the learning for the build process. I made heavy use of the website PC Parts Picker, and I started reading the forums where the gaming guys talk shop. I built this back in December 2019, and I decided to pay for a newly released processor so we could get some years out of it. When I opted for the “small form factor,” I thought it would be smaller than it is, but it doesn’t really matter. We have room on the boat for a full-size tower.

Here’s the parts list for my final build:

Intel Core i7-9700 Coffee Lake 8-Core 3.0 GHz (4.7 GHz Turbo) processor $349.99

Noctua NH-U12S – Premium CPU Cooler with NF-F12 120mm Fan   $59.95

Fractal Design Define Mini C MicroATX Mid Tower Case.  $79.99

Corsair Vengeance LPX 16 GB (2x8GB) DDR4 DRAM 3200MHz Memory kit  $74.99

MSI MPG Z390M Micro ATX Motherboard  $155.00

MSI Gaming GEForce GTX 1660 Ventus XS 6G OC Graphics Card  $227.99

Crucial P1 1TB M.2-2280 NVME Solid State Drive.  $99.00

Total price: $1281.89 

IMG 0207

As you can see in the photo above, I’m not sure how they get away with calling this a MicroATX Mid Tower. For someone who is used to laptops, this thing looks huge. And when I compare this to what you can buy that is similar in power and design, I’m not convinced I saved much money. But the big advantage I feel is that I learned so much, and as time goes on, I can easily increase the RAM if necessary, add a more powerful graphics card, or switch the built-in power supply from 110 to 24 volts. In the photo, you can see it is running on an AC converter since we are in Turkey with 240V and the computer currently runs on 110V.  The 24V power supply I looked at was $330, and since we don’t have the batteries hooked up yet, I went with AC for now so I could actually tell if my creation worked and start up the learning curve on Time Zero Pro. Perhaps I will pop for the other power supply in the future.


This Mid Tower computer will reside in the cabinet on the port side of the main helm behind the TV in the main salon. You can see that cavernous area on the far left of the photo above. The TV will be mounted on a swinging door that can be opened to access the air handler and the computer, as well as other networking bits and pieces.

Here’s the sort of computer we intend to buy for our second computer:

Fanless PC Industrial Mini PC Windows 10 Pro 16GB RAM / 512GB SSD Intel Whiskey Lake i7-8565u, TDP 15W8M Cache, up to 4.60 GHz, Quad Core 8 threads Desktop  Computer with HDMI/TPC/EDP Ports, M.2 WiFi, BT 4.0, 4K HD, RS232 / 485 COM, SATA 3.0 for 2.5 Inch HDD/SSD

Total price on Amazon: $917.00

Screen Shot 2020 03 08 at 6 23 18 PM

And the size is quite different! It has an 8th generation Intel Processor, so it will still support three monitors, but that does push the price up. At the moment, we only intend to have two monitors at the upper helm, but it is nice to know we will have room to grow. Screen Shot 2020 03 08 at 6 24 54 PM

Also, these are just basically Intel NUC computers, so I know they are expandable in terms of adding a larger SSD or more RAM.

This one will go into a cabinet that is just to port as you go down the steps into the main salon. Both computers will have dual LAN ports. Furuno is fussy about insisting that their hardware needs to be on its own isolated network. We will have a FAR 1523 radar, BBD-S1 bottom discriminating depth sounder, and the Axis camera encoder for our FLIR camera, as well as some exterior cameras on that network. All the wifi, additional cameras, Synology NAS, and other non-Furuno stuff will be on the other network.

For monitors, after a fair amount of research, we chose Litemax Navpixel marine displays. At first, I searched and searched for regular monitors, but since we only had room for two 19” displays at the lower helm, the choices were few. We didn’t really need the waterproof aspect, but I wanted them to be able to dim almost to black easily, preferably with a hard knob, and I wanted them sunlight readable, even for inside. We have so much glass in our salon, and our eyes aren’t getting any younger. By going direct to the supplier in Taiwan, we were able to get two 19” displays, two 24” displays, and one regular non-waterproof 43” monitor for about $8000.00 including shipping.

Screenshot 2020 03 08 19 11 19

This is a photo of one of the 24” monitors from Litemax. This is a full multi-touch,1920×1080,1000 nits sunlight readable, IP65 sunlight readable Marine Display.

One 19” TZT3 ChartPlotter sells for $8,495.00. To be fair, that includes the sounder, and we will have to buy the sounder module ($500) for our TimeZero software.

In addition to the TimeZero software, we will also have Rose Point Coastal Explorer software. We will have CS on our laptops for planning purposes, and for back-up in case we lose both of the ship’s computers. In addition, we have tablets and phones. For redundancy and back-up, we feel we are covered.

In the end, we won’t know until we get out there, but we’re both pretty happy with our decision to make Möbius an all-PC boat.

We will carry very few paper charts, just a few large area ocean charts, but we will have paper pilot charts. And in the event we lose all electricity, we both have sextants, a copy of the tables, and a nautical almanac on Kindle (with a tiny portable solar panel).

If I have to break out the sextant, I think it will be just like riding a bike.

Stay safe and healthy everyone. We’re on a long passage with this Pandemic, but as Wayne and I always say to each other when things blow up on us — This too shall pass.

Fair winds,


Update from the not so exclusive SIC Self Isolation Club!  Möbius XPM78-01 Weekly Update March 16-20, 2020

Update from the not so exclusive SIC Self Isolation Club! Möbius XPM78-01 Weekly Update March 16-20, 2020

Last Sunday, the 15th, upon our return from London for Christine’s B’day weekend we very willingly joined many of you I suspect as members of the Self Isolation Club or SIC as I’ve been calling it.  As my cousin Donna who is also a member of SIC in their home over in Doha pointed out, this is not a very exclusive club anymore unfortunately.  Christine and I are very grateful to be together through all this and to be in our wonderful apartment here in Antalya which so far seems to be one of the better spots to be in the world.  Antalya has an extremely large and modern medical infrastructure in part because this is a “medical tourism” destination and in part because Turkey has a very good medical infrastructure staffed by world class health professionals. 

While not being able to be at Naval Yachts and working on Möbius is a challenge, it is a very minor one compared to our challenges with being so far from our family, children and grandchildren who do not appear to be in as good a location in Florida, California and British Columbia.  Christine and I are both feeling very good, are fit and in good health and most appreciative of our situation.  We sincerely hope that all of you reading this are finding your ways to be safe, happy and healthy as we all weather this latest storm in our lives and remind ourselves, as we do when in severe storms on passages that “This too
shall pass”.

Here in Turkey closures of schools, restaurants and the like happened early this week and those who can are being encouraged to work from home.  However the rest of the work force continued to go to work this past week and we will have to wait and see what next week brings.  With thanks again to Yigit, Uğur and Hakan for sending me all their photos each day this week, I am also fortunate to be able to bring you this week’s Progress Update and as usual Team Möbius has been very productive so let’s go for a virtual tour of their hard work.

Mr. Gee Gardner 6LXB

IMG_20200310_185537Mr. Gee, which is what we call our Gardner 6LXB diesel engine, usually appears near the end of previous Weekly Progress Updates so let’s check in on him first this week.  Actually these photos are from the week previous when I had time to give all the large cast aluminium parts their first finish coats of high them aluminium paint.

The ribbed oil pan is in the bottom right, crankcase in the center and the two flywheel housings hanging in the background.
IMG_20200310_185542I had been thinking of just leaving the aluminium parts bare after sandblasting them thoroughly but I like a very clean engine and the cast aluminium can be a bit porous so I decided to cover all the aluminium with more aluminum in the form of powdered aluminium based paint. 
IMG_20200310_185551This is a silicone based paint that is specially formulated to withstand temps up to 300 C/ 572 F.  I’m very pleased with the results and next week when I can hopefully go back to Naval I will give these all one more coat of aluminium paint and then finish it off with a clear coat to seal it all fully.
IMG_20200310_185556This is the Port/Left side of the crankcase casting that is the “service side” of the Gardner as the factory photo below shows ……………
Gardner Marine 6LXB photo   data sheet………. how this is the side that has most of the engines parts that you access when servicing such as the fuel injection pump which is mounted with those two circular clamps you see above, fuel and oil filters, alternator, etc.

Click to enlarge if you’d like to read the basic technical specs on the Gardner 6LXB.
IMG_20200310_185608These two castings enclose the huge heavy flywheel and that flat surface on the Left one facing this photos is where it bolts to the aft end of the crankcase.  The housing on the Right has a SAE bolt pattern flange which matches the one on the Nogva CPP Controllable Pitch Propeller gearbox.

More on Mr. Gee as soon as my SIC membership expires and I can get back to work.
Fuel manifolds 3Even though he is one of the most efficient diesel engines ever to be mass produced, Mr. Gee needs a good steady supply of clean diesel fuel so we are building an extensive set of fuel filtering systems that include a pair of 2 stage Fleetguard filters, water separators, a fuel transfer and polishing system and a full Alfa Laval centrifuge that can convert even the dirtiest fuel into crystal clear diesel.
Fuel Tank manifoldsThis requires a series of manifolds and ball valves such as this pair in the Basement for transferring fuel from any one tank to any other.  Now we need about four more manifolds for the fuel transfer system, fuel polishing and Day Tank.
Fuel manifolds 1So the Machine Shop has been busy making these out of blocks of solid 75mm/3” square aluminium which they drill out and tap with NPT pipe threads for the SS ball valves.  You’ll see more of these as Cihan starts installing them in the Workshop.


.Day Tank hoses 3In the meantime though, Cihan is busy plumbing in all the fuel and water lines in the Workshop and Engine Room.  This is looking forward at the Day Tank on the Stbd/Right side of the Workshop with the ER wall on the Left.  You can see the water and fuel lines in the vertical trays on the Right and running across the ceiling and down to the ball valves atop the Day Tank.
Day Tank hosesThe area between the Day Tank and the Stbd hull is starting to be well populated as the various “highways” of support trays for fuel, water and electrical cables intersect.  The horizontal trays here are carrying electrical cables through the penetrations in the WT Bulkhead you can see at the far end. 

Vertical hoses are fuel and water hoses.
ER hoses penetration 2When all the hoses or cables are in, these penetrations are sealed to be fully watertight with a White special certified caulking compound you can see in this penetration under the workbench you see in the photo above.
Day Tank hoses 2Down below the Day Tank we can see more of Cihan’s handiwork with these water hoses which make the turn into the penetration through the ER Enclosure wall on the Left.
ER hoses penetration 7The clear hoses are bringing sea water from the intake Sea Chest in the ER back to the Watermaker low pressure Feed Pump and the Circulation Pump for the Webasto BlueCool Chiller.
workshop water manifoldThose water hoses run aft into these ball valves which direct sea water supply and return lines from the Watermaker Low Pressure Feed Pump and the AirCon Chiller Circulation Pump.
Watermaker LP pumpWith the ball valves installed Cihan mounts that SW Circulation Pump to the mount he has previously welded in place.
Watermaker LP pump mountsAs with all pumps and motors, this is mounted with these vulcanized vibration absorbing mounts.
Workshop deck wash pumpCihan also has both Deck Wash pumps mounted and plumbed.  This is the pump for the Sea Water Deck Wash with its clear filter covered with the white latex glove.  The Fresh Water Deck Wash pump is on the far Left of this shot.


Halyard Exhaust 4Yigit has been extremely busy managing all this work as well as designing and modeling all our systems and this past week we worked with the engineers at Halyard to finalise the design of our wet exhaust system and have them build and ship that to us ASAP.
Halyard Exhaust 2We have refined it a bit more but the earlier rendering below is close to the final design that Halyard is now starting to build.

Gardner engine is shown in the blue silhouette with the Red Nogva CPP gearbox in the bottom Right.  Exhaust gases exit vertically out of the Gardner and then run across the horizontal pipe to the blue mixing elbow where seawater is injected to cool and quiet as they collect in the large Silencer/separator on the Left.
Halyard Exhaust

Water is then separated and exits out the bottom into the Sea Chest while the cooled gases flow through the rubber S-shaped exhaust hose running down and out through the ER wall and over to the exhaust pipe exiting the hull above the WL

I will show more once we start installing the exhaust system.


Maretron Basement panelI don’t have too many pictures of Hilmi’s progress this week but we have been frequently connected via WhatsApp and he’s been continuing to install more and more of the Maretron BB’s Black Boxes and N2K cables.

For example, he and Cihan installed this new AL panel to mount the multiple Maretron BB’s in the Basement and is now busy wiring them up with their N2K cables and wiring from sensors for Bilge High Water and fuel tank levels.
Octo GXOne of the many networks on the boat is the one for all the Victron equipment which is the base of our AC and DC electrical systems.  Victron is another one of those tried and true solutions for us so we went all Victron for things like inverters, chargers, isolation transformer, MPPT solar panel controllers, DC-DC converters, etc..

Victron octogx system diagramThis is our Victron OctoGX, which we may swap out for the just released CerboGX and these both serve as a central communications device to bring all the inputs and outputs together and enable us to closely monitor all aspects of our electrical system. 

If you’re interested in more details, click HERE to see the new video from Victron that does a nice job of explaining the many functions of these devices.

Victron Cerbo GX Connections Overview diagramOn the XPM’s or any long range passage maker boat, this level of monitoring is critical as we literally live off of our electrical system and the consequences of losing any part of it can have eXtremely severe consequences for us.  So these comm centers put pool all the data from all the devices and allow us to know right away when anything changes.

In addition to the high dependency on the electrical system components, they also tend to be high initial cost items which we expect to work continuously for at least ten years so just as with human health, keeping our electrical system and all its many components all in top shape and catching any changes and problems early is key to long life spans for these devices.

DC strip outletsHilmi has also been installing other electric components such as these 12V and 24V DC distribution blocks.  We have these spread throughout the boat wherever we might want to power 12V and 24V devices. 
Round Anderson PowerPole panelIn addition to the 8 port model above, these also come in round 2 port models where fewer such DC connections are needed so we use a mix of both.

We tend to hide this inside cupboards and drawers or below countertops or desk tops to make cable management easier and keep them out of the way.
WindCamp 8 port 40A connectorThese blocks are very well made and require a single 12 of 24V DC power input which is then distributed to each of the Anderson Powerpole plug in sockets which are individually fused with an standard ATC blade fuse.  The block can handle up to 40 Amps which is more than enough for the various chargers, LED lights, fans, radios, and other DC powered devices.  Also super handy to have near my workbenches in the Workshop and my Boat’s Office.


Vent Box doors 3Uğur, standing, Nihat, kneeling, and Okan had a very busy week with their typically varied set of jobs such as continuing to install the many doors in the two Vent Boxes on the Aft Deck.  

This is the Stbd/Right side Vent Box which looks after all the Extraction air venting and ducting. 
Vent Box doors 2Door on the far Left and Right access storage areas.  Upper Middle frame is for the Extraction air from the Engine Room and Lower Middle frame is for the Extraction Air from the workshop, both with large axial fans built in.
Stbd Vent Box doors 2Both tops will soon have their AL plates welded on and a bit later these will be covered with some of the Aquamarine Marble countertop surfaces.  Taller countertop on the Left will be left as is and the electric BBQ Grille mounts into the lower counter surface on the Right.

The opposite Port Vent Box will be a single level marble countertop with a built in sink.  Should make for a great Outdoor Galley.
Steering pump bracketThey also whipped up this bracket for the Manual Hydraulic Steering Pump that will be installed inside the Main Helm.
Kobelt helm-pump-7012This will secure the Kobelt 7012 Helm Pump which is connected via hydraulic hoses to the Kobelt 7080 steering cylinders.  We will keep a traditional steering wheel stored nearby that can slide onto the 7012’s keyed shaft and enable us to steer the boat manually. 
Main Helm layoutHowever this wheel will rarely be in place as this is only a last resort backup steering in case either of other two independent 24V steering systems, AutoPilots and cylinders should ever fail completely.

The small gray hole in the center of this rough rendering of the Main Helm Area is where this steering wheel will be inserted if ever needed.


Front solar panels install 2However what stole the show excitement wise this week is this! 

The first three of our 14 solar panels are now being fitted.  These three 295W panels will be mounted to the frame you’ve seen being built in past weeks.  The frame is hinged on its aft end just in front of the center window of the SkyBridge giving it two modes:

1.  Locked down in about the position you see here when we are on passage.

Front Solar Bank Hinged 12.  Tilted up to be horizontal when at anchorage for both maximum solar gain AND to act as a giant wind funnel directing the breezes over the Bow to the big vertical vent Green Mist Eliminator grill you can see in this rough render.
Front solar panels install 3The three panels are fastened into the hinged AL frame.
Front solar panels install 5Once in place each panel butts up tight against each other to form a single continuous solar surface.
Front solar panels install 7Front two panels in place.
Front solar panels install 8and then there were three!

In addition to these three 295W hinged panels, there are 8 more 320W fixed panels atop the SkyBridge Roof and then three more 320W panels on the Aft Roof which cantilevers overtop the Outdoor Galley on the Aft Deck.

The combined output of all 14 panels gives us a theoretical total of 4405Wp.  We won’t know the actual output until we get out and can do some real world testing but being very conservative if we have the upper 8 panels working at 85% capacity and the three front and back working at 30% capacity a 5 hour solar day would generate about 13.6 kWh and a 7 hour solar day would generate about 19.1kWh
IMG_20200131_182106Each of our 14 solar panels have their own dedicated Victron 100/20 SmartSolar MPPT controller to maximize their output and give us the most control over losses from any shading of any one panel from nearby structures such as the SkyBridge Roof, Arch, Radar, etc.  If multiple solar panels are connected in series to a single MPPT controller then the shading of any one panel reduces the output of all the others as well.

Front solar panels install 9Here’s the “powerful” view from the SkyBridge.
Meanwhile down below all our “chippies” on the Cabinetmaking Teams have had another very productive week so let’s go check that out.


Master wallsŞevki and Selim continue to build out the Master Cabin.  All the Green/Gray leather wall panels on the Port/Left side are now snapped in place.
Master ceilingAll the ceiling panels are removable with FastMount clips holding them in place.  The ceiling grid has now been installed and they are installing the White FastMount female sockets you can see in the foreground and then two of the rough cut ceiling panels have been snapped in place behind.
Master ceiling 4View from the entrance into the Master Cabin looking forward to see that the rest of the rough cut ceiling panels have now been fitted and snapped in place.
Master washing machineHmmmmm, what do you think we are witnessing here?

Aha!  The Bosch Washing Machine has arrived and is now setting on the Master Bed frame awaiting installation in its cabinet on the front Stbd/Right side.
Bosch washing machineIt took quite some time but Buse persevered and was able to source a British version of this Bosch Washing machine Christine had picked out so that the engraved text is in English rather than Turkish.  (click to enlarge)

We are now quite used to the Turkish terms that are on the washing machine in our apartment for over 2 years now but still nice to have this all in English for our aging brains and others who might be using this. 

Thanks Buse!!

Oh, and yes, of course the washer has to have WiFi for my Gorgeous Geekette!

Master stair risersWe received this exciting photo on Friday as they put in the Rosewood stair risers for the first time.  This is the spiraling stairwell leading up from the Master Cabin to the SuperSalon which we will go look at next.
Before we leave the Master Cabin though let’s go look at what Faruk and Osma have been up to in the Master Head & Shower.

Master HeadThey picked up where the left off last week with filling all the joints between the fiberglass panels that form all the surfaces of the floor, ceiling and walls.  As you may recall from last week, they tape off each joint with two different layers of tape so they can put on two layers of grout to create a nicely radiused corner.

This past week they put in the 2nd layer with the final radiused corner and once dry they carefully wet sanded and polished the gel coat filled resin compound they use for the grout which creates a polished and seamless interior.
Master Head toilet shelfWith the joints all filled and sanded they could now install the lower sink cabinet and the base for the VacuFlush toilet you see on the Right with the patch of blue painters tape to protect the surface as they cut the hole for the toilet base.


Master stairs header 2Continuing up the stairs from the Master Cabin, Omur and Selim are now installing the rest of the Main Helm cabinetry with this section overtop of the Master Cabin door.  There will be a Black leather covered triangular lid atop the space to the right of Ömür’s hand which will lift up to access the surprisingly large storage space underneath.
Master stairs window sillThat allows Selim to start fitting the side panel which makes the corner transition from the panel above the door and caries on below the windowsill on the far Stbd/Right side of the stairway.
SS cabs 2Stepping back towards the centerline of the boat, let’s turn clockwise for a series of shots to see the layout of all the areas that make up the Super Salon.

Looking directly towards the Port/Left side of the SuperSalon shows the Main Helm on the far Left, Master Cabin stairs to the right of that, then the Dinette Settee and the front half of the Galley Cabinets on the Right.
SSalon seatsTurning to look at the Aft Port/Left corner of the SuperSalon shows the whole wrap around set of connected Galley cupboards.
Galley cab Blue Line 3Which you can see much better if I zoom in on the Galley at bit more.
SS cabsContinuing to turn clockwise you can see the stairs leading up to the Aft Deck in the background on the Right. 
The taller cabinet on the far Right side where the two 130L Vitrifrigo SS upright fridges will soon be installed and to the Right of that is the shorter more recessed cabinets where the twin Vitrifrigo 70L drawer Freezers will soon be parked.
Freezer TV w BHLRotating a bit more reveals the opening for the 50” SmarTV/monitor cabinet.
SSalon Helm areaOne more twist to the Right lets us see the Main Helm cabinetry.
SSalon stairsAnd one final twist to complete the full 360 photo tour we are back to the stairwell down to the Master Cabin with the Settee on the Right.
SSalon fwd viewHere’s a different perspective of the SuperSalon looking straight ahead at the Main Helm while standing at the base of the stairs down from the Aft Deck. 

The large open hatch in the center provides access into the huge Basement area which is under the entire area of the SuperSalon floor.
Galley GaragesOff to the far Right of the photo above here is a sneak peek at the first of the Galley Garages which sit atop the marble countertops and I look forward to showing you the rest of these Garages as they are installed next week.
Galley cab Blue Line 2And of course, the Blue Horizon Line or BHL you first saw being installed last week, continues to go in all around the circumference of the SuperSalon.

Whew!  Even though our 14 day self isolation prevented me from being there at all this week, I’m exhausted just taking you on this photo tour!  A big thanks again to Yigit, Yesim, Uğur, Hilmi and Hakan for keeping me so well connected to the build via WhatsApp text, video and photos all week and for providing me with all these photos so I can share it all with you.

With luck my membership in the Self Isolation Club hopefully expires next Sunday the 29th so I only have one more week until I can join Team Möbius at Naval Yachts.  But in any case I will be back with here next weekend to bring you the latest Weekly Progress Update of XPM78-01 Möbius.

We sincerely hope that all of you joining us here are finding your own ways to be safe, healthy and happy and that perhaps we can assist a wee bit with your entertainment during these crazy times.


Better Late than Never? Weekly Progress Update XPM78-01 Möbius May 9-15, 2020

Better Late than Never? Weekly Progress Update XPM78-01 Möbius May 9-15, 2020

Sorry to keep you waiting so long for last week’s Progress Update as it is already time for me to be posting this week’s!  I did manage to get one post up last weekend all about Captain Christine’s 2020 B’day Adventure so if you have not read that you might like to and it will help explain why I’m late getting this week’s update written and posted.

However just because we were away doesn’t mean that anyone else on Team Möbius at Naval Yachts were any less productive and perhaps even more so with no pesky owners to get in the way.  And thanks to Yigit, Hakan and Uğur all taking pictures throughout my absence I have LOTS for this week’s Möbius Show & Tell, so let’s dive right in. 


For no good reason I will go through the different teams in alphabetical order this week so let’s start wtih the Aluminium Works team of Uğur, Nihat and Okan,

IMG_20200309_101930Any guesses as to what Nihat is working on so happily?
IMG_20200309_101942Will it help to know that this is all 15mm/5/8” thick AL plate?
lewmar EST65 evo-els-series-electric-winchHow about if I give you a sneak peek at one of last week’s New Arrivals?

For those who might not recognize it, this is a Lewmar EST65 EVO ELS 24V self tailing electric winch.

And it needs a very solid home up on the bow deck, hence the 15mm plate
IMG_20200309_104145This is where it will go, right alongside the big Forepeak Hatch with a rectangular cut-out in the underlying Anchor Deck plate for access to the motor.

Crescent shaped gussets on the Left ……..
2Winch Box 1……….. will be welded inside to tie the sides of this housing into the underlying frames like this.
IMG_20200309_180320The 15mm top plate will be flush with the upper deck surface and tied into both decks and the Forepeak Hatch so this will provide the eXtremely strong and rigid base for the huge forces this winch needs to withstand.
IMG_20200310_093416Pretty quick job for Uğur to run the first pass of welds.
IMG_20200310_093529Climbing down into the Forepeak and looking up through that rectangular cut-out you can see how this winch housing has been welded on the inside with the additional gussets welded in as well.

This winch will be quite the workhorse for us with multiple uses such as helping to raise and lower the SkyBridge folding roof, pulling in shore lines when docking in high winds, emergency retrieval of the anchor if the Windlass fails and general use to handle large loads on lines at the Bow.

Aft Deck Vent BoxesWith the Bow Winch housing all built they moved Aft and started fabricating all the doors and mist eliminator frames in the two Vent Boxes on the Aft Deck which you can see in this rendering.

These vent boxes provide the waterproof ducting for all the air going in/out of the Engine Room and Workshop and have been carefully designed such that they cannot downflood with seawater during a 360 degree roll over.

IMG_20200312_102937This is the Port/Left side Vent Box which is for all the intake air. 

Stbd/Right side Vent box is for all extraction air.

The tops of these Vent Boxes will have marble countertops on them with a sink you can see here and a BBQ on the other side to create our outdoor Galley.
IMG_20200312_141757Nihat soon has the frame for this doorway tacked into the lower Port intake opening.  You can see the intake pipe on the inside lower Right corner in this and the photo above. 

This provides air for the Corridor and the Guest Shower so doesn’t need to be very large and we can use some of this area for storage if needed.
Port Vent Box doors 3Fitting the vented door.
Port Vent Box doorsOver on the Stbd/Right side Vent Box, Nihat gets busy fabricating the frames for the doors and Extraction Air vents.

The electric BBQ Grill will be mounted on that lower surface on the Right side and a marble countertop on the Left.

More to follow next week as they finish off these Vent Boxes on the Aft Deck.

MOBIUS Network Diagram-2

Christine has added “Network Engineer & Designer” to her long list of titles and this is the current version of her overall network diagram.

It may look a bit confusing but the colours make it easy to see the different network types and having this overview is very helpful to see all the interconnections.

As per the legend at the bottom Blue is for the NMEA 2000 or N2K network, Red is the Ethernet network and Black is for “other” such as communications networks such as VHF radios, AIS and other proprietary wiring for things like cellular and WiFi networks.

IMG_20200310_092853This week Hilmi was focussed on installing all the Maretron “Black Boxes” and the multi-port blocks for the N2K backbone.
Maretron N2K Builder diagram 2018.3

The N2K network is mostly used by our extensive Maretron monitoring system and as you can see in this diagram Christine has created with the very powerful Maretron N2K Builder app.
It is relatively straightforward conceptually with a continuous large blue “Backbone” cable that runs the length of the boat with all the Maretron devices and Black Boxes or BB, connected to it via T’s and Drop Cables.

IMG_20200311_145656Here in the Master Cabin for example, you can see how Hilmi has started to bring the Blue Backbone cable across the ceiling to bring it over from the Stbd to Port side.
IMG_20200311_123312Saying that we have an “eXtensive Maretron monitoring system” might be a wee bit of an understatement as this is just some of the Maretron N2K cables alone.

Here is what he is working on in the photo above which is in the cabinetry which is marked as “Master Cabin Stbd” in the Maretron diagram above if you want to follow along. 

The upper Maretron BB is a Switch Indicator Module or SIM100 which will soon have six Bilge High Water sensors attached to it and the lower BB is a Fluid Pressure Monitor or FPM100 which will soon have six tank level sensors connected to it.

The bottom block is a Multi-Port which is basically a series of T’s all put together in this one block.
IMG_20200311_145528Mounting the BB Black Boxes and Multi-Ports is very quick and easy but it takes a bit longer to do all the cabling, especially when you take the care and attention which Hilmi does to run every wire “just right”, support them throughout their length and label each one.

IMG_20200311_145552The Red/Black wires going into each BB have the tank or bilge water sensors on the other end and bring their individual outputs to the BB which is then connected via a Grey Drop Cable into the Multi-Port which in turn is plugged into the Blue Backbone cable to carry all this data back and forth through the system.
IMG_20200312_141657With that done, Hilmi moves over to the Port side of the Master Bed labeled “Master Stateroom Port” on the Maretron diagram above and installs two more Maretron BB’s. 
IMG_20200311_184054These are the same type BB’s as on the previous Stbd cupboard; one SIM100 for Bilge High Water sensors and one FPM100 for more tank level sensors and they start out like this …..
IMG_20200312_153038……. and then Hilmi works his magic and they are soon all wired up and look like this.
IMG_20200312_153525This is the home of our Aft Electrical Distribution Center which is starting to call Hilmi’s name as well so you will soon see him working his magic on these “plain” old AC and DC electrical wires and all their respective DIN rail circuit breakers so stay tuned for more from our Sparkies.


Continuing our alphabetic run through, let’s to check out what Omer and Muhammed have been up to in the Guest Cabin area.

IMG_20200309_102233Omer has turned his attention to the Guest Shower and is busy prepping the foundation for the ceiling panel.  Nice big hatch to bring in lots of light and fresh air when you are showering.

And remember that vent pipe you saw inside the Port Vent Box that Nihat was working on in the photos above?  Well here you see the other end of it where it will connect to the ceiling with a diffuser.
IMG_20200309_180833Ceiling installed and the back wall will be next.

Once these have all been covered with 10mm marine plywood the Fiberglass Team will come in and glass all the walls, ceiling and floor into a seamless and fully sealed space the same as you’ve been seeing them do in the Master Cabin Head & Shower.
IMG_20200309_180845As you’ve seen elsewhere, where there are access ports to the integral fuel and water tanks below the floors, there will be a removable floor panel to provide access to these ports on the rare occasions when you need to get into a tank area for things like annual inspections.
Guest Head 2Opposite the Shower is the Guest Head and Omer and Muhammed are now installing the Ro$ewood cabinetry that has just come back from the Finishing Shop gleaming with their fresh coats of hand rubbed PU varnish.

The sink sets atop the counter area on the far Right with the hole for the drain pipe visible here.
Guest Head 3But that is quickly covered up with cardboard covers and blue tape to keep those surfaces clean and protected with the build goes on around them.

Cihan will soon be in here installing all the plumbing for hot and cold water, drains and toilet.
Boat Office cubbies 3Outside of the Guest Shower & Head is “my” or the Ships Office and Corridor leading Aft to the Workshop on the Let here.  Omer and Muhammed are now installing the desk and drawers that span this whole 2.5m/8’ long length.
Boat Office cubbies 2Turning to look forward towards the stairs leading up to the SuperSalon and that Electrical Distribution Panel we saw earlier, you can see more drawers and “cubbies” on the Right side of the desk.


IMG_20200310_092848Moving forward into the Master Cabin we find Selim (Left) and Şevki busy working on the cabinetry in there.  This is looking Aft at the stairs coming down from the SuperSalon with the Bureau of Drawers on the Left, King bed in the middle (covered with tools) and the floor area on the far Right side of this photo.
IMG_20200309_180504They too have been installing the cabinetry that is now flowing out of the Finishing Room as you can see with that beautiful long Rosewood panel along this Port side of the bed. 

Wall panels are also now out of the Upholstery Shop and have been snapped in place with their FastMount clips.
IMG_20200309_102636This is what the back side of each panel looks like.  The Black male FastMounts press into the White female sockets you can see in the far wall grid.  This is a bit expensive but pays for itself many times over by providing very long lasting solidly mounted panels which don’t move or creak and yet clip out in seconds to provide access to systems behind.
IMG_20200309_180516The AirCon and Heating Air Handler will soon be installed in this bedside cabinet and the forward one will be more storage.  Spiraling stairs leading up to the bed provide spots for the intake air vents for the Air Handler.
IMG_20200311_145834We are particularly delighted with the way this “floating” bedside table has worked out and gives Christine (this is her side of the bed) the perfect spot to set her phone, Kindle, books etc. 

Note too the juxtaposition of those Blonde patches of the Rosewood grain!  And yes, still worth every one of the many thousands of pennies this costs.
IMG_20200311_145616Up overhead the ceiling grid is being installed quickly and it too will soon have lots of FastMount clips for the removable White leather ceiling panels to snap into.
IMG_20200311_145628_MPBacksides of all the Stbd/Right hull side cabinets are having their frames installed for the similarly removable panels on the back of each cabinet.
master cabin cupboar backs 2Stepping back into the Shower area to get this overall shot of just the forward section of cabinets and wardrobes that now have their back panels in place.

Bureau of Drawers on the Right, Vanity sink on the Left.


IMG_20200310_183234Faruk and Osma continued their eXcellent work in the Master Shower and Head.

They now have the one piece floor pan installed and the Shower seat has also been glassed in place.  Drain holes, bottom for the Shower and Top for the Head area are ready to be routed out for their respective SS drain plates.
IMG_20200310_092835As you’ve been seeing in previous weeks, they lay up all the individual pieces over in their Composite Shop using templates they have made up in the Shower & Head and then bring them back to be glassed in place. 

Here Osma is setting upper panel that goes above the glass wall in place after he lathered the back of it with some thickened resin.
IMG_20200312_141604When all the panels have been glassed in place all the corners and seams are taped off so they can be filled with thickened resin and gel coat colouring.  After the first round of filler has been carefully applied as it has here, the innermost brown tape is peeled off.  This leaves a wider area for the second and final round of filler to be applied with a nice radius.
IMG_20200311_145248Up above, Faruk trims the ceiling panel to be perfectly flush with the inside surfaces of the big 700mm/28” hatch which will flood both the Shower and the Head with lots of fresh air and light. 

Because the two corner walls of the Shower are glass, it will also bring all that beautiful natural light into the rest of the Master Cabin and really make Sherry’s artistic patterns etched into the glass even more stunning.
IMG_20200311_155313More Maretron sensors everywhere you look.  This cable is for the proximity sensor in each door and hatch to remind us if any hatch or door has not been fully closed before we head to sea.  Same idea as the lights on the dash of most cars that alert you if a door is not fully closed.

Hole in the background is for one of the LED ceiling lights.
IMG_20200311_155257Down on the floor, the one tank access port has been framed for its removable panel and the Head floor drain on the Left has been recessed for …………
IMG_20200311_155125……… its flush fitting SS drain grate.
IMG_20200311_155226The sink countertop and cabinet will soon be glassed into the lower area here with matching and mirrored Medicine cabinets above.  But you can see that there will be plenty of easy access to all the systems behind such as these water manifold ball valves.


The ever jovial Cihan has been his usual productive self of course so let’s go see some of his latest handiwork.

IMG_20200310_092944This is the Aft Stbd/Right side of the SuperSalon where the Galley cabinetry is about to be installed, but just before it arrives from the Finishing Shop Cihan has done a masterful job of squeezing in this 100mm/4” PVC ducting.  On the far Left side it goes through a waterproof penetration in the floor to extract air out of the Basement and then …..
IMG_20200312_153638……… on the far Right upper end is a T, closed off with blue tape here, where the exhaust from the induction cooktop vent enters. 

Looking closely on the far Right (click to enlarge any photo) you can see how this pipe continues straight aft and up into the Stbd Wing Box where a large axial extraction fan pulls all the air to the outside.
IMG_20200310_143037Directly forward from the PVC ducting Cihan has been working on the Stbd side Webasto Air Handler to change the output air duct from rectangular to round.
IMG_20200310_183101And then quickly has it fully installed on the insulate floor prior to the Dinette Settee being installed.
IMG_20200310_183356Directly across the SuperSalon just in front of the twin Freezer Drawer cabinet he has similarly mounted the Port side Air Handler.  As with all equipment, we use boded rubber flexible anti-vibration mounts which you can see an example of on the far Right mount here.  These help insure that none of the vibration or noise is transmitted to the hull or the room.  I’m a bit maniacal about having an eXtremely quiet boat interior so we are going to great expense and lengths to ensure that the XPM’s are going to be acoustic sanctuaries.  Can’t wait to do some testing with a sound meter while underway!
IMG_20200312_103113Remember those shots in the Guest Head up above?  Well here you can see that Cihan has been busy there too installing the SS threaded PPR elbows for hot and cold water PEX tubing up top and the drain pipe from the sink down to the Grey Water tank or Sea Chest below.
IMG_20200312_103023Continuing Aft to the forward end of the Stbd side of the Workshop where the diesel Day Tank resides, we find more of Cihan’s many skills on display.  He is eXtremely adept at building and installing all the many mounting plates and WT penetrations where he needs to run pipes and hoses.  In this case he has made up that oval tube you see in the center of this shot that provides the penetration in the ER wall on the Left for some water hoses he needs to run.
IMG_20200312_141348Peeking way in the back corner under the Day Tank you can see one of these penetrations already welded in place and filled with water hoses coming out of the Engine Room and the second penetration tube ready to be installed below for more.
IMG_20200312_153732A bit more aft along that same ER wall there is one more penetration now welded in place.  This one will soon have the six big cables from the two huge 6kW Electrodyne alternators coming through on their way the their external rectifiers what are mounted up on the Stbd hull side wall.  I’ll go into more of those details when we start installing those cables and alternators.


Finishing up our alphabetical cabin tour for this week with the always Super Salon, let’s go check out what Omur has been up to there.

IMG_20200310_183106The flow of cabinets coming out of the Finishing Shop continues into the SuperSalon as we see here with these freshly varnished Galley cabinets that are now being secured to their foundations.
IMG_20200310_183125Opposite angle of the Galley standing up in the doorway coming in from the Aft Deck.

Induction cooktop goes atop that unfinished plywood to on the Right here with the Speed Oven below.  A deep SS double sink will be installed in the marble countertops in the upper Right corner and the rest as you can see is all drawers. 

There is one more length of cabinet to go in the bottom corner of this photo.
IMG_20200311_145210A great shot of how beautiful the contrast is between the rich dark hues of the Rosewood and the bright inner Beech surfaces of all cabinets and drawers.
IMG_20200312_152931Dinette Settee going in next.

You can see that Air Handler we saw Cihan installing earlier inside the large opening so that I can easily access that cavernous space below the outer side decks.
SuperSalonThis wider angle gives a fuller view of the whole aft area of the SuperSalon and our Master Cabinetmaker Omur.  Settee on the far Left, Galley in the upper Left corner, stairs up to the Aft Deck in the background and the double Fridge cabinet on the Right.
Main Helm angled wallThe angled mini wall on the Stbd/Right side of the Main Helm is being mounted here and some of the cables coming up from the Basement into this Forward Electrical Panel are brought up for the final time.
Master stairs switchesYesim, our brilliant interior designer is pointing out the location of the light switches that are so conveniently positioned as you go up or down the stairs to the Master Cabin.
SSalon thermostatsSimilarly , the three digital thermostats are being mounted in this short wall at the top of the stairs where the Settee ends.  The two Black screens control the two Webasto AirCon/Heater Air Handlers and the White one controls the In-Floor heating in the SuperSalon.
Blue LineFinally, perhaps saving the most exciting new progress for last, most of you can probably guess what Yesim is showing us here?

Correct!  This is our infamous “Blue Line” as the team here tends to call it and what Christine and I refer to as our Blue Horizon Line.  For those of you who have not read about this previously, this is a design theme and feature we came up with that is based on our most typical situation of being anchored off some little island or on long passages where our world is surrounded by 360 degrees of a blue horizon line where the blues of the sea transition into the blues of the sky.

We decided to bring this outdoor feature indoors and have designed the interior spaces and materials such that everything below the Blue Horizon Line matches up with materials, textures and colours that are below the horizon such as wood, stone and the aqua marine blues and greens of the seas.  Everything above the Blue Horizon Line similarly match up wtih the colours and textures of the sky with softer materials and shades of white and grey.
Galley BlueLineOur interior Blue Horizon Line, let’s shorten that to BHL for now, is made up a an aqua marine swirl we created with Yesim and had printed on thin strips of clear acrylic.  It’s absolutely amazing the range of materials you can print things on these days and it is neither very difficult or expensive. 

Galley BlueLine 4As you’ve been seeing as the cabinetry has been built, we incorporated this BHL as the back surface of the smooth flowing continuous hand rails that flow around all the furniture and walls at about waist height.  With the cabinetry now coming out of the Finishing Shop Omur and team are now starting to glue these strips of BHL onto the back of all these recessed handholds.
Galley BlueLine 3This is the BHL as it flows around the Galley cabinets and just wait for a few weeks until they start installing the aquamarine marble countertops to see how this ends up bringing the outside in.
SSalon BlueLine 3Here is a look at a more fully finished BHL around the top of the cabinet for the two Freezer drawers.
SSalon BlueLine 2Zooming in a bit to show how this all comes together both visually and functionally as a continuous handhold for everyone no matter their height.

Lots more of this to show you in the coming weeks as more cabinets, walls and BHL are installed.


This week had a LOT of new arrivals as what we hope will be the last big shipment of equipment from the US has arrived here at Naval Yachts.  Too many items to show you all  of them but here are a few highlights to give you an idea.

IMG_20200309_111312As you can see the majority of our equipment comes from Defender Industries and I want to first give an eXtremely big shoutout to Wendy Pandolfe <> who has been absolutely awemazing to work with throughout the past year or more as we put together multiple sets of orders for hundreds of items from screws and fittings to our whole Furuno navigation system and pretty much everything in between.  Wendy is a fabulous problem solver with that great “can do” and “get ‘er done” attitude that is all too rare and is SO much appreciated. 

*** Just to be clear we have NO form of sponsorship or other relationship with Defender and simply and seriously recommend that you consider Defender for your next marine outfitting supplies and equipment.  I have put Wendy’s Email above and if you contact her just say Wayne & Christine sent you and I’m sure you will soon share our enthusiasm and appreciation.

IMG_20200309_104741Why would I be happy that my Beautiful Bride and Captain is kissing anything but ME??

That’s easy when the recipient of her affection is the #1 bit of kit on our boat that lets us Sleep Well At Night or SWAN as we call it. 

Meet our 110 Kilo ‘/ 242 Lb Rocna anchor.
We spend hundreds of nights at anchor every year on every kind of bottom,  through every kind of sea condition and weather and our lives very literally depend upon our anchor and chain to hold us in place.  One of THE worst feelings for anyone at anchor is to feel your boat dragging anchor which of course would most likely occur at O’Dark Thirty in the worst conditions and with a lee shore rapidly approaching you.  So we go to perhaps the most eXtreme lengths in over engineering and designing our complete anchoring system from anchor through chain and windlass.

Anchor selection borders on a religious argument amongst cruisers and the good news is that there have never been more great choices available.  Christine and I certainly spent a LOT of time discussing and researching which anchor to chose for Möbius and in the end decided to do as we have with many other critical components and gone with what has worked eXtremely well for us on  our previous boats and experiences. 

IMG_20200309_111320Both of us have had oversized Rocna anchors on our previous boats and boats we have delivered for others and in the thousands of sets we have done over more than ten years, we have never had our Rocna drag once. 

As with all my comments on this blog please be clear that I am NOT saying that this is the “best” anchor for you, simply that this is the anchor we are willing to bet our lives on and the Goldilocks choice that is just right, just for us.
maxwell-vwc4000-windlass-24v-only-12Almost as important as having the anchor solidly holding us to the bottom is being able to bring it and up to 100m/330ft of anchor chain all back aboard quickly and safely.  With several hundred kilos of anchor and chain to bring aboard this takes some equally robust equipment and again we have gone with what we know to work best for us and this Maxwell VWC 4000 windlass was also in this last shipment from Defender.
IMG_20200309_145626One of the most critical aspects of the windlass is that the “gypsy” matches the chain size and fits the chain like a glove.  Gypsy is the name for this wheel driven by the big 24V motor on the windlass that pulls the chain aboard.
IMG_20200309_145630Hence each Gypsy needs to be ordered to exactly match the specific chain link size you have.  In our case this is 13mm G40 DIN766 chain and as you can see the Maxwell Gypsy does indeed fit like a glove.  Whew!

IMG_20200309_115138With literally hundreds of individual items in this shipment alone, the next task was to go through every box and check them against the order invoices to make sure that everything had arrived, none of them were damaged and that they were all the correct models.  Hilmi and Yigit kindly pitched in to help unpack everything and Christine and I spent the rest of the day going through the lists and sorting everything into boxes and containers by family and type.
IMG_20200309_115135Here for example is one of three boxes of electrical system components that Hilmi will soon be installing throughout the boat.  The majority of these are for our primary 24 Volt DC system which is what the whole boat is based upon.  All our other electrical systems for 12V DC and 120V and 230V AC are built on top of our 24V 1350Ah House Battery Bank.
IMG_20200309_115145This is one of three boxes full of the components for our Maretron monitoring and N2K system you saw being installed above.  This box just has some of the N2K cables and the other boxes were filled with sensors and all the Black Box combiners.
IMG_20200309_115149Sorting through the many, many meters of Dyneema and rigging.  As with the anchor decision, we have used Dyneema line on our previous boats with great success so we have gone with all Dyneema for pretty much every line on the boat from Lifelines to Tender Lift tackle lines and Paravane rigging. 

I will be showing you much more of the details of our use of Dyneema as we install these systems as well as all the other gear that arrived in this week’s shipment.
And that’s the week that was March 9-15, 2020. 

As you may have read in my previous post all about it, Christine and I landed back in Antalya late Sunday night returning from our long weekend trip to London for her birthday to find a very different world than the one at the start of this week.  Upon landing we became willing members of the not so exclusive Self Isolation Club and our membership lasts through March 30th so we are not able to be back at Naval Yachts until then.  However thanks to all the efforts of the rest of Team Möbius and all the photos Yigit, Yesim, Uğur and Hakan so kindly send me every day, I will be back shortly with next week’s XPM78-01 Progress Update so stay tuned!

Spring has Sprung in more ways than One!  Progress Update XPM78-01 Möbius March 02-07, 2020

Spring has Sprung in more ways than One! Progress Update XPM78-01 Möbius March 02-07, 2020


As this photo attests the weather here in Antalya the past few weeks has been spectacular and very Spring like.  Last Sunday Christine and I took a break to go for a nice Sunday drive along what is apparently called the “Gulf of Antalya” which is a crescent shaped coastline that runs approximately East/West with the majority of the city of Antalya stretched in thin strip along this coastline for over 30km. 

IMG_20200301_145851We were not the only ones out enjoying this sunny Sunday and one of the parks we walked through had lots of colourful kites for sale with grinning children at the ends of balls of string  and their kites flying high above us.

I’m writing this a week later on another equally as brilliant of a sunny Sunday and hopefully I can get this posted in time to go out and enjoy it more.

The warmer and sunnier weather seems to have a Spring in the step of everyone else on Team Möbius as well and as a result there is lots of progress to show you so let’s get started.


Dorade Boxes ForedeckUğur, Nihat and Okan had a very productive week applying their significant skills with aluminium to several projects and one of the most gratifying to see was the completion of the four Dorade Vent boxes on the Forepeak. 
dorade box drawingThe simple concept of Dorade Box Vents have been used on boats for a very long time as they provide a way to bring fresh air inside the boat in rainy weather or high seas while keeping all the water OUT side where it belongs.

The work this week was to mount the new Vetus Cowls on the AL Dorade Boxes, finish installing the shut off lids in the Standpipes and then weld the Dorade Boxes to the ForeDeck.
IMG_20200302_102640_MPYou may recall previous posts showing the construction of the Dorade Boxes and here Nihat is creating the slots or “Scuppers” along the bottom edge that ensures any water that enters the Dorade Box flows out onto the deck and overboard.
IMG_20200302_102648Uğur then takes over to mount the White/Red silicone Cowls to the tops of each Dorade Vent.  The Cowls act as big air scoops to grab all the breezes blowing over the bow and direct them down into the Dorade Box and then down the Standpipe into the interior below.

Nice simple mounting system with these silicone Vetus cowls which use the Grey plastic threaded ring in the foreground which is bolted and sealed to the top of the Dorade Vent Box to provide the attachment for Grey threaded collar you see at the base of the Cowl.

A slight loosening of the collar allows the Cowl to be rotated to any angle you want or turned 180 degrees to face aft if there are larger waves bringing water onto the decks.
Dorade Vent Lid drawingBefore welding the Dorade Boxes to the Foredeck, they needed to finish installing these threaded Standpipe Storm Lids.  This drawing I created shows how these work by having a center threaded rod with a knob on the bottom you can turn by hand to lift or lower the round lid to open or completely seal off the Standpipe.
IMG_20200302_112827The Standpipes and the internal radial support were welded in place several months ago and so this week they worked on building these Lid assemblies.
IMG_20200305_172327For a bit of added sealing, there is a groove cut half way through the thick Black rubber gasket.
IMG_20200302_112748We applied our KISS approach and just used double SS nuts with Loctite to attach the AL Lids and Knobs to the threaded SS rods rather than welding them just in case they ever needed to be removed.
Vent Lids 1This is the end result with the Lid fully raised to let in the maximum amount of fresh air.
IMG_20200302_152243Or fully closed and sealed off.  The vast majority of the time we will leave these Lids fully open and only close them when heading into eXtremely severe seas when there might be the possibility of waves breaking over the bow and overwhelming the Dorade Boxes draining capacity.
The Vetus Cowls have the option to be fully removed and replaced with solid discs that would seal them off but this would still leave the Standpipes open so we took the “belts & suspenders” approach and added these adjustable lids to enable us to fully seal off these vents.


Looking up inside one of the Standpipes from inside the Master Cabin you can see it is easy to reach up and turn the knob.  This ability to close these Standpipes while you are INSIDE the boat was a big safety factor in our decision to go to the time and expense of adding this additional shut off capability. 
IMG_20200302_152334_MPAs with so many aspects of building the boat, all the time goes into the preparation leading up to the final installation so after several months of working on the various parts of these Dorade Boxes,
Dorade box weldingNihat and Uğur can at last weld them to the deck.
Dorade box welding 3A quick hit with the brass wire wheel cleans up the welds and work surfaces and the Dorade Boxes are all done.  We’ll leave the Cowls off until we Launch to keep them out of the way as work continues on the ForeDeck and Bow areas.
IMG_20200305_172308We used the same system of fully sealable lids on all the vent pipes coming into the interior in other places such as this plate which bolts to the ceiling above the Main Helm area.
Underside PH Vent under overhangThere is a large box or air plenum behind the Red slots in the Pilot House Roof overhang you see here
IMG_20200306_182215This plate, standing on its end here, then bolts to the ceiling to form the bottom surface with these five vent pipes to direct fresh air into the Main Helm area.
IMG_20200304_122640Work on Vent Boxes continued with Uğur and Nihat welding up these side covers which bolt in place on the inside vertical surfaces of ……
Wing Boxes ……. the two Extraction Air Wing Boxes on either side of the very Aft end of the Pilot House on the Aft Deck.  You can see one off to the Right of the spiral staircase and the other on the far Left. 
Vent box lid millingThe Vertical Milling machine made quick work of cutting all the slots and holes in these eXtraction vent cover plates and then …..
IMG_20200303_181750Uğur welded these boxes to the inside.  A large axial fan will bolt to the top surface you see on top here and when turned on this fan pulls air out of the extraction pipes inside the Wing Box which run into the Corridor, and Guest Head/Bathroom below.
IMG_20200304_122946Switching from venting to wiring, Uğur and Nihat also installed the penetrations through the Engine Room Enclosure walls for electrical cables to run through. 
IMG_20200304_122954The two in the upper Right in the photo above and center here, are for the AC wiring for lights and switches inside the ER.  Once the wiring is all run these will be filled with special watertight caulking to keep the ER and the Workshop fully separated and WT.
IMG_20200304_151225Diagonally opposite on the ER they welded in this similar penetration down on the aft Stbd/Right corner of the ER where all the high amp DC cables from the two 250A @ 28V alternators and carry up to 14kW over to the DC distribution box that will be mounted up above the Workbench on the Stbd/Right side of the hull walls.
Finishing up with AL work for this week;
IMG_20200304_175654Okan put the finishing touches to the hinged rack that will soon hold three of our 300Wp solar panels on the front roof area of the Pilot House.  More on that once we start mounting the solar panels.
Paravane winch plateUğur welded the plates for the Paravane rigging winches to the bottom of the hinged Arch.


IMG_20200305_153653Most of Hilmi’s work this week was not very visible as he raced ahead of the interior installation teams to put in the wiring for things like the 120V, 220V, 12V and 24V receptacles spread throughout the boat.

But this quick peek into the Aft Electrical Distribution box off the Corridor by the Guest Cabin will give you an idea of what he has been up to.
IMG_20200303_100510Hilmi has also been spending more and more time in the Workshop as he wires up the various system components which are mounted there. 

This is the control box for the Watermaker
IMG_20200305_153538Which is off to the Right here and some of the other AC & DC wires and cables leading to the area on the Left where the Workshop Distribution panel will mount.


IMG_20200305_153528Speaking of the Watermaker, Cihan was busy this past week doing more of the plumbing for it such as the foil covered high pressure lines you see here running from the Watermaker up to the four membranes on the ceiling.
IMG_20200306_144637_MPOn the far Right side of the WM, near the WT door from the Swim Platform, Cihan has now got most of the plumbing in place for the Webasto BlueCool AirCon unit which has been moved out of the way for now. 

To Red accumulator tank and the Supply/Return lines for the sea water cooling lines are in place and ready to be connected to the Chiller unit.
IMG_20200305_153411Always a good sign for me to see that little red hose in the background as that’s where Cihan will attach an air line to pressurize and test the plumbing for leaks.
IMG_20200302_102933And more good signs as we see the soapy solution being applied to the joints to see if there are any leaks.
IMG_20200302_151305The system is left pressured overnight to see if it all holds, which it did.
IMG_20200302_151335The IsoTherm Calorifier or Hot Water tank has most of its plumbing in place; Safety Valve bottom Right, Mixing Valve for In-Floor Heating lower Left, Mixing Valve for DHW upper Left.  Two more lines bringing hot water to/from the Gardner and the Kabola diesel boiler still to be added to the White capped off fittings.
IMG_20200302_102925Both pumps for the Domestic Water pressure fully plumbed and covered in protective bubble wrap.


IMG_20200304_123318Transitioning from Plumbing to Heads & Showers, the Composite Team has been busy glassing in the Master Head on the far Right and Shower on the Left.  They use flat sheets they make in house for the large flat areas on the walls and then build molds for things like this corner box section that makes the transition from the walls to the ceiling. 
Rectangular cut outs on the Right are where the large 2 mirrored door Medicine Cabinet will be mounted and provide access to systems behind the wall.

IMG_20200306_183308Areas such as this Shower Seat are first laid up in molds in the Composite Shop
IMG_20200304_150718and then brought onboard to be glued in place with resin.
IMG_20200304_150707Faruk on the Left and Osama are extremely skilled at this and everything fits just right.
IMG_20200305_172059Once they have the pieces affixed they start taping up the joints in preparation for filling them in.

Now they are busy building the molds for the large floor and ceiling pans and you should see those next week.


Master ceiling prepThis wider shot helps to show how things are shaping up in the Master Cabin with the Shower in the center area and the Head behind it. 
Wardrobes and bureau of drawers lining the Stbd/Right hull and the wall beside our bed on the far Left here.

IMG_20200305_172103Şevki and Selim are now staring to put the Port/Left hull wall back together
IMG_20200302_103406_MPAnd prepping the ceiling with mounting blocks for
IMG_20200303_182140…. the ceiling grids.  Weight reduction cut outs marked
IMG_20200304_123901….. and cut out……
Master ceiling cutouts…… and attached.
IMG_20200305_172140More excitement as some of the removable wall panels emerge from the Upholstery Shop!


IMG_20200303_100225The SuperSalon has been rather vacant of late with most of the cabinetry over in the Finishing Shop to be varnished.  This is looking aft towards where the Galley will be in the Aft Left corner, stairs up to the WT door in/out of the SuperSalon from the Aft Deck, double Fridges go in the cabinet on the far Right and open hatch into the Basement in the bottom Right corner.
IMG_20200302_103258But the tide is turning and finished cabinets are starting to flow onboard with their lustrous varnished surfaces all aglow.  Double opposing door Fridges in the background and double drawer style Freezers in the Foreground.
IMG_20200302_110102_MPWe, well OK me, is a bit maniacal about eXtremely well insulated Fridge and Freezer boxes so even though our Vitrifrigo units come with the latest and greatest insulation from the factory we are adding at least 50mm/2” more rigid foam insulation around all sides and the backs of all four units and 100mm/4” on the bottoms.

IMG_20200302_112540Omur has the Freezer cabinet upside down to put in the insulation in the bottom area before he mounts this to the floor in the background which has another 50mm/2” of insulation.
IMG_20200303_181950Up front the Main Helm has been getting its own insulation, this time for acoustics.
IMG_20200305_153718Header for the door into the Master Cabin is now fitted.
IMG_20200306_102456 As are details such as this transition piece where the upper rear corner of the Fridge cabinet meets up with the big thick SuperSalon glass windows.

Black conduit carries solar panel cables down from atop the SkyBridge roof to the Basement.
IMG_20200304_104412Over in the Cabinetry Shop, Omur is also routing out the openings for the hidden hinges such as the one you can see on the far Right here.
Garage hinge cuttingLaid down on its side for Omur to work on, this is the Galley Garage that sits atop the marble countertop.
IMG_20200304_104428 These are small versions of the hidden hinges we are using on the full size interior doors you saw last week and these smaller ones ensure the Galley Countertop Garage doors all open smooth as silk at a touch of your finger on the solid mechanical latches.


IMG_20200302_103302_MPLots of work on ceilings this week and Okan is bringing the freshly epoxy coated ceiling grids for the Guest Cabin and Ship’s Office aboard.

IMG_20200302_103232 Once the ceiling grids are in place in the Guest Cabin he won’t be able to do this so Okan is taking advantage of the last chance to pass the large ceiling grid panels down through what will soon be the Galley countertops.
IMG_20200302_112534Sure enough, a couple of hours later the ceiling grid is in place in the Guest Cabin below and no more access from up above here.
IMG_20200302_151735Omer, Muhammed and Okan soon have the ceiling grids all securely fastened and leveled in the Guest Cabin.
IMG_20200304_180037Omer is meticulous and detailed so he is going around and sealing any small areas between the ceiling grid and the mounts to the AL frames above and making sure they are fully insulated so there is no thermal transfer.
IMG_20200305_171948Next up, Omer turns his attention to installing the Ro$ewood door frame to the Guest Shower.
IMG_20200306_144506The floor in the Showers are raised to provide enough room for well sloped drains and the In-Floor heating PEX tubing so …..
IMG_20200305_172004…….. the bottom door sill is higher than the other doors.
Shower door frameOnce all the parts of the door frame fit, they are glued in place.
IMG_20200306_144518Hakan is conferring with Omer on some details with the Shower drains and you can see what a masterful job Omer has done with all the matching grain patterns which flow across all parts of the door frame.  The door itself will be plate glass for added light and openness in the Shower and when walking in/out of the Guest Cabin on the far Left.


Let’s go upstairs to the Finishing Shop for a peek at what our Polyurethane wizards are up to;

Beech shelvesWe can’t let the Rosewood steal the show every week and these Beech shelves are more than up to that task. 

Looks like a wizard of a different kind in the middle here?  What do you see?
Finishing Galley stairs cupboardThe Beech you can see on the inside of this Galley cupboard alongside the stairs up to the Aft Deck, has to my happy eyes, a beautiful contrast with the darker tones of the Rosewood and then also matches up nicely with the Blonde islands that naturally emerge within the Rosewood in many areas.
IMG_20200306_182851More of that creative contrast on display within this section of the Galley Countertop Garages.
IMG_20200306_183035Even though this back panel that the 50” SmarTV mounts to, setting on its side here, will rarely be seen by most it will bring great joy to my heart every time I see it and just knowing it is there.
IMG_20200306_182946This will soon be the top surface of the double Freezer cabinet but right now it is huddling in the back of the Finishing Shop with its brothers and sisters waiting to be carefully wrapped in bubble wrap while they await their final trip onto Möbius.

Mr. GEE our Gardner 6LXB Single Engine

IMG_20200302_163249_MPI was able to get away from all my other boat building duties a bit more this week and all day yesterday (Sat) and got some time to move Mr. Gee further along. 

This is a special cylinder honing tool I have had great success with in the past and I’m using it here to put the final just right 45 degree cross hatch pattern on all the cylinder walls.

If you look closely you can just make out the thin line where the new dry cylinder liner has been pressed into the cylinder black casting.  After pressing them in place they are precisely machine bored to original factory diameter which enables the block to be returned to same as new condition.
IMG_20200302_171757This cross hatching s a critical detail that ensures that not all the oil is scraped off by the piston rings on each stroke so that there is just the right amount of lubrication to reduce the friction and wear.
IMG_20200302_171742The process goes relatively quickly and I soon have all six cylinders in good as new condition.
IMG_20200307_143721_MPNext I turned my attention to the major cast aluminium components such as the massive crankcase in the foreground, the cast ribbed oil pan in the far Right background and several smaller cast covers on the Left. 

All these parts had all been sandblasted several months ago and I gave them a light coat of primer so I now gave all surfaces a thorough wet sanding to get them ready for final coat of primer.
IMG_20200307_143730I taped off all the openings and hung up the two big AL castings that form the flywheel housing on the aft end of the Gardner.

I am using a special ultra high temperature primer that is good for up to 600 degree C/1112 F which is WAY hotter than needed but works well to stick to the aluminium which is notoriously difficult.
IMG_20200307_164515A few hours later …….
IMG_20200307_164538once the fan had cleaned out the air ……
IMG_20200307_164609…… you wouldn’t know that these castings have been in service for almost 50 years and they were all ready for their final colour coating to bring them to better than new condition.

Stay tuned, much more of Mr. Gee’s renovation to come in the following weeks.


IMG_20200306_100016Ending as we have been doing with the New Arrivals here at Naval Yachts things were much slower than the past few weeks but no less exciting for me as this load of thick wall 150mm / 6” OD AL pipe arrived.

Any guesses what this will soon become?
IMG_20200306_100021Will it help you to show you that this is eXtremely robust pipe?

mobius_r25y99I’ll have much more details to show you in the coming weeks but this is for building the Davit system for bringing our Tender on/off the Aft Deck once Yigit has it fully developed in Rhino.
mobius_r25y9Until then these quick renderings, thanks to Yigit, will have to tide you over.

And that’s what’s all of us on Team Möbius have been up to this first week of March 2020 over here at Naval Yachts in Antalya.

We REALLY appreciate you coming along with us on this adventure and please add any and all comments, suggestions and questions in the “Join the Discussion” box below.



Leaping Forward:  Progress Update XPM78-01 Möbius Feb 24-28, 2020

Leaping Forward: Progress Update XPM78-01 Möbius Feb 24-28, 2020

Good thing 2020 is a Leap Year so we get an additional day to work on Möbius here at Naval Yachts as the time goes flying by and I can barely comprehend that it is already the end of February 2020.  However as you are about to see and read below, the progress is very believable and that’s all we can ask for as everyone leans in to push us ever closer to Launch Date. 

We get a lot of questions about “When will you launch?” which is quite understandable, we think about it too, and I finally have an answer for you; Thursday.  Not to be flip about it but the reality is that we don’t know the exact date when Möbius will be ready to dip her beautiful aluminium belly into the waters of the Med other than my second response which is; as soon as possible or ASAP.  I might even borrow and tag on one of my favorite quips, apparently from Albert Einstein “and not one bit sooner”, which he apparently said in reference to simplicity as in “Everything should be made as simple as possible but not (one bit) simpler.  We are all working towards the shared goal of building the best boat we can that will meet and exceed the clearly outlined fundamental principles which Christine and I have created based on our decades of full time sailing and live aboards.  This is further exasperated by the fact that this is very much a “version 1.0” boat of the XPM class so most things are completely new to all of us.  We are all working as hard and as efficiently as possible towards this mutual goal and so “Thursday” and ASAP, seems to be the best answer for the launch of our Goldilocks boat.

So let’s go see what Team Möbius has been up to this past week and you can decide how well it is going.


Let’s start this weekly update with our Aluminium Team of Uğur, Nihat and Okan now that they are back after almost a month away while Uğur was out with his badly broken thumb.

IMG_20200228_100024 I’m going to be mean and hold you in suspense for a wee bit longer about what exactly this three massive AL bars are for but the wait sill soon be over in the next week of two once they start installing these in the hull.  I can give you a hint that these will be very solidly welded into the hull and they will be in the Aft Deck area.
IMG_20200228_100029My hand will give you a better sense of their size and 50mm/2” thick mass.  All the sharp corners are about to be fully rounded over including the edges of the large hole in the top. 

Does that help you guess what these are? 

Stay tuned, answer coming soon.
IMG_20200227_181651Moving on to the next quiz, any guess as to what this new AL frame is for?
IMG_20200228_100001Here it is mostly completed now and ready to be lifted up onto the front of the roof of Pilot House.

Now you know right?
PH Vent Tunnel under solar panelsCorrect!  This is the frame that will hold the front three (in Blue) solar panels which fit overtop of the angled space in the front roof area of the Pilot House.
Front Solar Bank Hinged 2This frame or rack will be hinged on the aft end in front of the SkyBridge windows such that it can be raised when we are at anchor such that the solar panels are horizontal or whatever angle puts them perpendicular to the sun’s rays.
Front Solar Bank Hinged 3Then when we are heading out on passage, the whole solar panel folds down and locks into the angled recess in the PH roof.

As you may recall seeing last week, our solar panels have arrived so I will soon be able to show you photos of them being installed in this rack on Möbius.
PH Vent Tunnel with solar panels offIn our typical “Swiss Army Knife” strategy of making as many things as possible serve multiple purposes, when lifted up the hinged solar panels creates a fabulous wind tunnel to capture all the breezes blowing over our bow at anchor and direct them down through that bright Green frame you see at the end of the “wind tunnel” and then down into the SuperSalon below.

IMG_20200226_142439So while they were working on the PH roof, Uğur and Nihat also fabricated and installed the Green frame you see above.
Mist eliminator frame on floor 2The flanges of the L-bar frame will be used to mount the Mist Eliminator grills which remove most of the salt and humidity from the air flowing through and further increase the comfort of everyone inside.
Mist eliminator frameAnd here is the fully installed frame all ready to have the Mist Eliminator grills bolted in place. 

You can see how the fully EPDM insulated interior surfaces have been covered with AL foil cloth to increase the air flow down into the air plenum on the ceiling of the SuperSalon below.

The Red & Black cables will soon have their MC-4 connectors on their ends to attach to the outputs of the three Solar Panels and then run down into their individual MPPT controllers in the Basement.

Dorade Vent Lid drawingI received several questions about this drawing I showed last week of the vent shut off lids we have built into all the Dorade and other vents bringing fresh air into the interior of the boat so here are a few more pictures to better answer those questions.
IMG_20200225_151742Consistent with my opening Einstein quote about “as simple as possible but not any simpler” or as I usually refer to it KISS Keep It Safe & Simple, you can see how that applies to these simple yet effective vent shut offs. 
IMG_20200225_151753This is the simple to fabricate inner frame that holds the threaded rod in the center of the 100mm/4” ID vent pipes when it is welded in place. 

Not pictured but you can see in the drawing above, there will be a simple knob on the bottom of this threaded rod and a round plate on the top so to close these vents you just reach up inside and turn the knob to bring the rubber lined lid down and sealed against the vent pipe. 

Given the build in water shedding design of Dorade vents we will only need to do this in eXtremely severe seas when we think there might be a chance of a roll over.  Hopefully that ends up being NEVER!  But you also never know.
IMG_20200226_110552Jumping down below, Uğur and Nihat picked up on their work to install the Prop Shaft removal tube in the Rudder which just came back from the waterjet company next door who cut the complex angled hole for this pipe.
IMG_20200226_110523Here it is from the other side where the prop shaft would slice through when being removed

This is one of the many examples of us applying the lessons learned from decades of sailing the world.  When, never if, you need to remove your prop shaft it adds an appreciable amount of time and work if you need to first remove the rudder and then replace it when you’ve got the prop shaft back in.  Simple in theory, this hole through the Rudder nicely solves that problem by making the eliminating the need to remove the Rudder.  As is often the case though, executing on this simple solution is quite complex.


IMG_20200224_140749Hilmi has also been off sick the past few weeks and is till not back to 100% but he was able to get several important jobs done this past week.

Starting here with the wiring of the three 230V and then the ……..
IMG_20200227_131237……… two 120V Victron Multi-Plus Inverter/Chargers on the other side of our Victron Rack in the Basement.

IMG_20200224_140756We’ve always had great experience with Victron products on our previous boats so we are using them throughout Möbius. 

The high amperage carried by the 24V amp cables requires doubling up two 70mm2  cables and as you can see Victron provides for this with dual positive and negative bus bars inside each inverter charger.
IMG_20200224_182341We find that connections overall are particularly well thought out in Victron equipment.  All the AC and data wiring comes up through WT cable glands in the bottom of the cabinet and the slots for the larger DC cables are well insulated with nylon inserts all around.  This kind of attention to detail makes it so much easier to access in the future and to connect initially. 
IMG_20200224_140906Hilmi has a good selection of special tools for thigs such as this hydraulic cable lug swaging tool.  I have a similar one I carry onboard as well for whenever I need to make up new cables. 
IMG_20200224_140921Fully tined lugs on the ends of all the DC cables provide an eXcellent resistance free connection BUT only if you create a perfect connection between the copper wire of the cable and the inside of the lug.  These tools make that much easier and I have yet to have a bad connection inside lugs I’ve installed so we are aiming to continue that trend on Möbius.
IMG_20200224_155302We also need Hilmi at 100% because this is only one small collection of the many electrical devices that are piling up in our store room and a new shipment arrives on Monday!

Seen here are some of the many Maretron black boxes for monitoring systems throughout the boat, the FLIR night camera in the top Left and some of the OGM nav lights on the right.

Mr. GEE our Gardner 6LXB Single Engine

IMG_20200225_153738I wasn’t able to give Mr. Gee as much of my time as I would have liked this past week but he did get some TLC such as this newly machine flywheel which just returned from the neighboring machine shop.
IMG_20200225_153748The massive flywheel needed two modifications the first of which is machining the recess your see here with the 8 M14 threaded holes where the AL SAE14 flange I’m holding up will be bolted on.  This AL flange has a series of rounded “teeth” on its inner surface where the rubber flexible coupling slides into and transfers all the power from Mr. Gee’s crankshaft to the Nogva CPP Servo Gearbox and propeller.
IMG_20200225_153801They machined this inner recess such that the SAE14 AL flange is a slight press fit onto the flywheel to ensure both parts are eXactly concentric and spinning on center with no vibration.

The second job was to machine this outer recess on the outside edge of the flywheel.
IMG_20200225_154040This recess is needed so that the flywheel clears the inside of this aluminium housing that surrounds the flywheel and bolts to the Gardner engine block.
IMG_20200225_154047You can see the clearance that has been created for the inner edge of the flywheel housing and then there is a similar clearance underneath those threaded holes between my fingers.
IMG_20200228_133541I also started to ready the many aluminium parts that bolt to the outside of Mr. Gee such as this water manifold on the Starboard side of the block that I’m holding and the coolant overflow tank in the upper Right and the water manifold below my arm on the bottom Left.

All these parts will be sand blasted and many of them will be polished to a gleaming shine to help create the work of art and engineering that is Mr. Gee.
IMG_20200224_180348One of the many unique features of our Gardner 6LXB which makes it so incredibly strong and long lasting are these threaded through rods which extend from side to side at the bottom of the massive cast AL crankcase. 
IMG_20200224_172402Each pair of rods extend through each aluminium crankshaft bearing cap and creates an unbelievably strong and solid “bottom end” to this engine.  This degree of solidity eliminates any vibration or flexing of the crankshaft and provides a truly rock solid base for it to spin freely in for another fifty years.
IMG_20200224_134607One last part I worked on this past week was a new spacer for the camshaft.  This part establishes the just right amount of lengthwise play of the camshaft which is supposed to be .004-006” but over the many years of non stop spinning in his former life, this had grown to .009” when I tested it so I drew up this quick hand sketch for Yunus, which is Turkish for Dolphin BTW,  in our Machine Shop so he can make a new one.  I will show you that when I’m installing it next week or so.


IMG_20200224_111720Cihan our Master Plumber was busy as always throughout the boat  so let’s go see what he’s been up to this past week starting up on the anchor platform on the Bow where he is installing these two wash down outlets.
IMG_20200224_141040One is for Fresh water the other for Salt.
IMG_20200224_141102We first experienced these beautifully made SS and plastic quick connect fittings on a boat we were delivering a few years ago and were so impressed by how well they worked we tracked some down for our four deck wash fittings; these two at the Anchor Platform on the Bow and then two on the Aft Deck.
IMG_20200224_141111As you might know I am loathe to allow ANY penetrations of the deck plating but I’m happy to make an exception to these two in the Forepeak area.  As you can see they are very well sealed and even if/when they do leak many years from now the water would go straight down into the bilge area below.
IMG_20200226_181249At the very opposite end of the boat, Cihan was also hard at work installing the complex network of pipes, fittings, mixing valves and manifolds for the hot water system.  You are peeking underneath the Starboard/Right side workbench at the very aft end of the Workshop where the IsoTherm Calorifier/Hot Water Tank is located. 
IMG_20200226_181255This is one of two manifolds in the hot  water system which provides hot water for both our DHW Domestic Hot Water for sinks and showers as well as for our in-floor heating system that runs through all the interior floors on the boat.

I will have more of Cihan’s craftsmanship in the coming weeks as he completes this system.


IMG_20200226_105156Let’s go back up to the front of the boat and catch up with the new Composite Team who have been busy glassing all the walls, floor and ceiling of the Master Cabin Shower.  In the past few weeks you have seen them complete the initial glassing by applying a layer of fiberglass resign and cloth to all the plywood surfaces.  Next they cut out these 3mm/ 1/8” thick composite panels with White gelcoat outer surfaces.

IMG_20200227_104615The shapes are rather complex with no right angles anywhere to be found so they built templates inside the Shower and use these to cut each panel to match the shape of each area,
IMG_20200226_105208Then they apply a layer or thickened resin and press each panel into place with bars and clamps.and clean up any squeeze out.
IMG_20200227_130931It all goes quite quickly as the panels cover relatively large areas.  The two rectangles on top Right are where the two mirrored upper cabinets will mount and the two lower ones are for the lower cabinet with the sink on top.  The cut outs provide access to the plumbing and electrical systems behind.

The two etched glass shower wall panels will complete the corner closest to you.
IMG_20200227_182432The “Shower Tower” mounts on the diagonally angled wall on the Left and the seat with its own access door is on the Right with the grinder on top.


IMG_20200225_102018At the other end of the Master Cabin, Omur, Selim and Şevki are finishing up the cabinetry for the bed area.  All the White dots on the headboard and dropped ceiling are the female FastMount clips where each of the upholstered panels will snap in place.
IMG_20200227_182607Zooming out you can see more of these FastMount clips on the end and side walls now ready for their Ultra Leather upholstered panels.
Wall panels being upholsteredSpeaking of which, here is a sneak peek into the Upholstery Shop of some of the wall panels having their foam and Green/Gray Ultra Leather applied.  We’ll have much more of this to show you in the coming weeks.
IMG_20200225_182637Looking up above the dropped ceiling we can see that it has now been solidly attached to the overhead AL frames of the hull with three AL L-brackets and now White epoxy coated spacers are attached for the ceiling grid to mount to.
IMG_20200225_182646And off to the Starboard/Right side of the Dropped Ceiling the solid Rosewood header above the Master Cabin door has been fitted.


IMG_20200224_111254Moving up to the SuperSalon it has been pretty much gutted this week as all the cabinetry has been fully fitted and has been taken over to the Finishing Shop where about five coats of Polyurethane varnish are applied and rubbed out to a beautiful satin lustre.

IMG_20200224_111559With all the cabinets gone, Selim on the Left is now busy putting in all the pink rigid foam insulation as he preps the floor for cutting in all the U shaped grooves for the 15mm/ 5/8” PEX tubing for the in-floor heating.
Galley acoustic insulationAt the Aft end of the SuperSalon where the Galley is, Selim is also now able t install all the 4 layer acoustic insulation panels  in these White stepped inner surfaces that make the transition from the Galley countertops to the Guest Cabin below.
IMG_20200224_111426Up at the front of the SuperSalon, the Main Helm station is being completed with both wiring and cabinetry being installed.

The angled Helm Dashboard with two 20” monitors is in the center with a large triangular storage area on the Left and angled wall on the Right with the forward electrical panel below.
IMG_20200224_141813_MPBefore heading to the Finishing Shop the Cabinetry makes a stopover in the Cabinetry Shop so Omur and Selim can do the final sanding and preparation for final finishing.  Here Omur is cleaning up and sanding the inner surfaces of the opening where one of the two Fridges will eventually be installed.  All five surfaces of these Fridge and Freezer walls will be lined with 50mm / 2” of rigid foam to insulate their already highly insulated Vitrifrigo boxes.
IMG_20200224_182915Selim and Omur add some of the details to the SuperSalon cabinetry such as cutting in all the ventilation grooves into the back panel where the 50” SmarTV will mount.
IMG_20200225_102616These vents are needed to provide a ready source of fresh air for the Port/Left Air Handler that is housed in the area behind and to the Left of this TV panel as well as one of our House Computers which is behind this hinged TV panel.

The multi directional TV mount will sit flush inside the rectangular box in this panel so unfortunately you won’t see this work of art too often, but when we do ………………………….
IMG_20200226_181828_MPElsewhere in the Cabinetry Shop, Omur and Selim are also finishing up more details such as this door in the outside panel of the Galley Counter that runs alongside the stairs leading up to the Aft Deck entrance door.
IMG_20200227_131801Both the door and its outer frame are made of solid Rosewood so that’s what you see them fitting in these phots.
IMG_20200228_142300With all the grain fully matched of course!


Guest ceiling grid w OmerNever one to be outdone in the friendly competition between our two Cabinetry Teams, Omer has been hard at work finishing things up in the Guest Cabin.
IMG_20200227_130507His latest project has been installing the ceiling grid that provides the foundation for mounting all the ceiling panels, lights, ducts and hatch trim. 

The combination of 12mm/ 1/2” lightweight Poplar marine plywood and all the lightening cut outs keeps this grid very light yet very strong.
IMG_20200225_101903Down on the ground, Omer has also been installing the same 12mm marine plywood on the floors.

tank access portsThe aluminium plates are all access ports to enable us to access all the baffled areas in the four diesel fuel tanks underneath. 

Each of these access ports in all areas of the boat will have their own fully finished floor covers that can be lifted out if needed but will normally be largely invisible.  Each one of these removable floor panels have specially made SS threaded hold down hardware to prevent these hatches from coming loose in the unlikely event of a full roll over.
IMG_20200225_120720The floors of the Corridor outside the Guest Cabin get the same floor treatment.

BUT, can you spot the most exciting new development hiding in plain sight in this photo????
IMG_20200224_141412Hint, it was a multi team project and Omer is working on part of it here and …..
IMG_20200224_150347…….. here.
 IMG_20200224_181604That’s right!  The first of our shiny new WT Bofor doors is being installed!!

Nihat is threading the SS bolts through from the Workshop side of the Corridor with Omer helping on the other side.
IMG_20200224_181741Which looks like this when they are finished and it is closed.
IMG_20200224_182038_MPAnd like this when open with Uğur nicely framed as he cleans up some of the Sikaflex adhesive used to seal the door to the aluminium bulkhead.
IMG_20200224_181839This is the only WT door on the interior so it is powder coated White.  Bofor custom built this door to eXceed all requirements for strength and water tightness even if the boat were to be completely flooded on one side. 

The other two WT doors are external doors, the main entrance from the Aft Deck into the SuperSalon and the door into the Workshop from the Swim Platform and they also exceed all requirements several times and but are left in raw aluminum. 


cabinets awaiting finishingAs you can imagine things are really piling up in the Finishing Shop as all the cabinetry is taken off the boat and brought to them for the final preparation and then spraying of the PU varnish.
Freezer cabinent finishingJust the first coat on this Freezer cabinet but looking good already!
cupboard backs being finishedThe Ro$ewood doesn’t get all the attention as these Beech tops of the Dinette seats can attest.
Santos transition piece finishedand size doesn’t matter either as all parts large and small, such as this bit of transition trim where the Fridge cabinet meet up against the window glass.
IMG_20200225_122805Each piece spends quite a bit of time in various parts of the Finishing shop as they have to be carefully sanded down between each of the 5 coats to get all surfaces fully filled and flat for the final coat. 

This is the top of the Fridge cabinet after its 3rd coat.
IMG_20200225_122959Once they have all been fully finished and polished they are carefully bundled up in lots of bubble wrap as they await their final move to their new home inside Möbius.


Flooring gridsThis is the new arrival this week.

Can you guess what these are?
IMG_20200227_105809_MPHow about if I bring in the special testing model on Team Möbius?

IMG_20200227_105813This is a very cool product that Buse and Yigit were able to find and we will use this for the flooring in the Forepeak, Workshop and Engine Room.

It is a special cast resin based composite that is used for things like walkways in harsh industrial plants such as chemical production.  Also used on some high traffic walkways on bridges, marinas and parts.  Easy to cut to shape and able to support thousands of kilos/pounds so very rigid.
IMG_20200227_105838You will see much more of this as we start installing it and we are super eXcited about this great new solution for flooring in these critical work areas inside Möbius.  These allow us to still see all the way below and each floor panel will be removable for access as needed.
Whew!  Another busy week here at Naval Yachts and as I said at the beginning you can see that the progress continues unabated as we head for that Thursday Launch Date! Smile

Thanks for joining us again this week and please join the team by adding your questions and comments in the “Join the Discussion” box below.

See you here again next week I hope.
