Oh Captain, My Captain! XPM78-01 Möbius Progress Update 13-17 Jan. 2020

Oh Captain, My Captain! XPM78-01 Möbius Progress Update 13-17 Jan. 2020

This was a week full of wonderful gifts the first of which is that Möbius now has her one and only official Captain! 

Captain Christine hat   eps 2020Christine flew back to Florida last week in large part to finish here marathon of testing and certification with the USCG for her 100 Ton Captains License.  Christine first received her 100 Ton license a few years ago in her early twenties but things have changed a wee bit in the ensuing years and this USCG license now covers many, many more topics and at great depth so this was truly a marathon of new learning and studying for many months. 

After a full afternoon and evening of testing Christine passed every one of the individual qualifications with flying colours and was informed that she is now a fully certified USCG 100 Ton Captain with the “six pack” option as well which additionally entitles her to captain boats with up to six paid guests aboard.  We don’t have any plans to use that, but she had this designation previously when she used to run a chartering business in the Caribbean so she figured she might as well keep it and added that to her testing and certification.

So please join me in congratulating and welcoming Captain Christine aboard her newest boat, the Good Ship Möbius.  Way to go my Beautiful Bride!  I could not be more proud of you nor want to serve any other Captain at sea or in love and life.

And if you promise not to tell anyone, I’ll let you in on a little secret ……………………………………………………. I get to KISS that Beautiful Captain every night before we go to sleep so yes, the rumours are true, the little Möbius Cabin Boy is sleeping with the Captain!!   But don’t tell anyone OK???

But wait!!  There’s more!  

As if having a newly minted Captain wasn’t already enough fabulous news, we got more this week with the confirmation that three of our five children and two of our three grandkids now have their flights booked to come join us here in Antalya for American Spring Break in April!  Daughter Lia, husband Brian, son Skyler and granddaughters Brynn and Blair will be here for over a week in what has become a bit of a tradition of having a family get together during this time when teacher Brian and the kids are all off school.  Hard to tell just where Möbius will be or in what condition at that time but we will at least get to spend time sharing our new home with these dear family members as well as showing them this part of the world which we have come to love so dearly as well.  More to come on all that as it happen but now let’s get on to the other news of the week with what has been happening with the building of the first XPM here at Naval Yachts.


Just to mix things up a bit, I’ll start with the “New Arrivals” this past week.

IMG_20200116_114705Any guess what Yigit knows is all wrapped up in inside this pallet full of boxes?
IMG_20200116_115229Uğur lent a helping hand and was just as curious.  The unusual L shape of the two big boxes might give you some clues……………..
IMG_20200116_120037How about if I tell you each box contains one of the same thing and give you a peek inside this one to show you the colour of the Ultra Leather?
IMG_20200116_115950Heating up your clues with a glimpse inside the other box and its slightly different colour leather.  And some of you more boat savvy people might recognize the brand logo?
LLebroc Main Helm Chair exampleThat’s right!  How fitting that Möbius’ Captain’s Chairs should arrive this week just in time for Captain Christine to test out on her return next week.  I will hold off unboxing until she is here so will give you this example from the LLebroc company web site to give you a better idea of what the “Bandera Series 2” Captain’s Chair will look like.
LLebroc Trades CX HB Upper Helm Chair exampleWe went with this higher backed and more snug fitting Tradewinds CX HB model for the Upper Helm in the SkyBridge where the motion might be more pronounced due to being up higher above the waterline.  You can use your imagination to map the colours you see in the two examples above onto these chairs while you await the full unboxing with Captain Christine.
IMG_20200116_115756I did pull out one of the footrests which as you can see are up for the task of matching the eXtreme strength of the XPMs.  I’ll show you the even more robust air adjustable pedestals when we set them up.

I had put a Llebroc helm chair on our previous boat “Learnativity” and after sailing her largely single handed for the first ten years I literally lived in that chair 24/7 on the many ocean passages I made and LOVED this chair.  When Christine joined the crew in 2013 she was equally amazed at how great these chairs are to spend hours and hours in while being super comfy and super safe.  We have tried out many other makes and models but always kept coming back to Llebroc and so we decided to do as we have done with much of the equipment on Möbius and go with what we know.

OLYMPUS DIGITAL CAMERAAnother example of Llebroc helm chairs.  We met up with Nick Covey at the Llebroc booth at FLIBS the Fort Lauderdale International Boat Show last year and kept going back over the three days we were at the show and Nick could not have been more patient and expert in answering our non stop questions as we dug into all the details of their new chair construction, features, materials and options and then sat down with him and ordered up the two Goldilocks just right just for us chairs. 
Now we can’t wait to be sitting in them aboard Möbius so stay tuned as we get to installing them.

IMG_20200117_103915OK, on to the next new arrival and next quiz; what’s inside these two new wooden boxes that arrived this past week?
This one is a little more obvious with these two boxes being so clearly branded but for those not familiar this is the propulsion system for our Tender.  The XPM Tender, which is being designed and built here at Naval Yachts will be all aluminium, of course! with a hull length of about 5m/16.45’ and beam of about 2m.  It will have an inboard diesel engine powering a jet drive and that’s what’s in these two boxes.

IMG_20200117_104851Many of you will be familiar with the Yanmar name of marine engines and this is a 2 Litre 82kW/110HP four cylinder 4JH4-HTE model.  Most notably for me this is a rare model that has “old school” mechanical fuel injection rather than electronic common rail.  A “must have” for me for two reasons; I can maintain and repair it with tools and equipment I carry onboard and there are no electronic black box to be damaged by things such as lightning strikes.
IMG_20200117_104627It is turbo charged but I’m good with that based on my previous experiences and should be good for many thousands of hours of operation and serve us very well.  For those wondering why we chose such a powerful engine for our Tender it is largely because we intend to have our Tender be our emergency propulsion system in the highly unlikely event that Mr. Gee our Gardner 6LXB main engine should become completely incapacitated and I was unable to get it up and running.  Given that this is a Gardner, that is eXtremely unlikely but as you’ve read here many times we practice “Readiness for the Unexpected” in the design and build of XPM’s and especially our Möbius.  I will have lots of details on how we will make this work in future posts.
IMG_20200117_104617We bought this engine and jet drive as a complete package from Denpar Marine and Selim Yalcin has been outstanding to work with putting this all together with us.  It is a very complete package and about the only things we need to add is a water lift muffler and a starter battery.  This is the gauge cluster that comes with the Yanmar and all the other components from alternator to cables and filters are in the crate with the engine.

IMG_20200117_104224Castoldi Jet drives in Italy might be less well known to you as jet drives are not as common as outboards but they have been building jet drives, both as complete Jet Tenders as well as just the Jet Drives themselves for over 50 years since 1962.  They are one of the largest manufacturers of jet drives and we are eXtremely excited about how well this will power Möbius’ Tender.
Castoldi jet drive position on hull TD224DAAs per the DD in the model name, this is a Direct Drive which helps us with our focus on KISS Keep It Safe & Simple by having a direct connection through a short cardan shaft CV joints.  This section view Yigit created lets you see the whole assembly. 
Castoldi 224DDCastoldi designed this 224DD model to be specifically matched with and direct driven by this 110HP Yanmar which factored into our decision as well.
IMG_20200117_104231As drive systems go, this is a relatively simple and eXtremely tough setup.  The majority of the drive itself is all solid cast aluminium with the impeller and its housing being all stainless steel.
IMG_20200117_104224One other very nice feature is inside the bubble wrap on the right side of the crate here which is a solid aluminium mounting frame which will be welded directly into the AL hull of the Tender and ensures a perfect match for the AL body of the jet drive itself to bolt to.
Jet drive steering and control diagramJet drives are most popularly known for their use in recreational jet skis but they are also very commonly used in workboats and tug boats due to their phenomenal steering and 360 degree of thrust which enables them to “hold station” at any point no matter what the forces of currents or tides might be doing.  For us this figures well into our both our day to day use of the Tender making it very easy to maneuver as well as acting as a tow boat or tug boat if we ever need to help out other boats in distress or ourselves.

Then there is the playful side of our Tender when we are using it to explore our surroundings, take multi day trips up rivers and estuaries and most of all having fun with our grandkids and other family and friends.  Having no propeller makes this all MUCH safer and have extremely little draft so we can get into the shallowest of areas, swamps and sandy or coral strewn bays.

I look forward to showing you MUCH more about our Tender in upcoming posts but let’s get back to the progress Team Möbius made this week.


IMG_20200117_162347Let’s start with this handsome and fun loving guy, Cihan, our prolific plumber.  He’s getting ready to plan out the installation of our wash down system with both Fresh and Salt water pump  outlets on the Foredeck and Aft.  We’ll show you more of that next week as the installation gets underway.
IMG_20200113_121345Cihan also our master of mounts and he is getting ready to create a new set of mounts for these two Johnson Aqua Jet Uno Max 5 chamber diaphragm pumps with built in 2L accumulator tanks to eliminate any pulsing and have very even flow.  These provide all our house water pressure throughout the boat and we have two for redundancy.  If one goes out a simple flick of a switch brings the other one online.
IMG_20200117_130255_MPHere they are all mounted on their noise cancelling soft mounts and ready for plumbing and wiring.  Each pump produces about 20L/min/5.2GPM at about 2.8 bar/41 PSI and should keep us with all the fresh water pressure we ever need.
IMG_20200114_103348Cihan installing two more of these 24V Johnson Viking 16 diaphragm pumps on the WT Bulkhead in the Basement with the Master Cabin on the other side.

One of the running jokes on the Team is that for a boat with “no bilges” we sure have a lot of bilge pumps!  16 to be exact. 
IMG_20190117_144519[1]This is in reference to the characteristic of having all our floors being tank tops and hence other than under the engine there aren’t really any bilge areas. Rather we have “gutters” running down both sides of the hull where the tank tops angle down to join the hull at a 90 degree angle for maximum strength such as you can see in this example by the steps going up from the Corridor in the Guest Cabin area.

They will likely almost never see water but each one still needs its own bilge pump as they do not run through from Cabin to Cabin area.

IMG_20200113_174228This shot looking forward towards the bow from the aft end of the Master Cabin is a good example of Cihan’s plumbing prowess everywhere you look.  Hull sides now filling up with plumbing carrying everything from Fresh, Black and Gray water, fuel, vent lines, Bilge water, hot water and now the floors are filling up with their runs of the Red PEX tubing for the in-floor heating.  Finished wall partitions now going up for the Shower and Head in the upper Left.
IMG_20200113_121431Same story back in the Guest Cabin now that all its cabinetry has been taken back to the Cabinet shop on their way to the Finishing Department.
IMG_20200114_102627Some of that PEX tubing snaking its way through the Master Shower floor with manifolds for hot and cold water on the hull sides on the Right.  Vertical Black pipes in the Yellow collars are for the drains from the Shower and Head floors we saw a few weeks ago with the nifty “smart water sensor” in the little Yellow manifold just visible on the middle far Right which connects to a diaphragm pump in the Forepeak.
IMG_20200113_174416I got a few questions about how the in-floor heating PEX lines were fitting into the rigid foam board insulation with the 10mm / 3/8” marine plywood atop so I grabbed this close up to show how that looks.  You’ve previously seen how they used a hand router to easily create the U-shaped grooves in the foam, then lined those grooves with aluminium tape and pressed the PEX into place.  The plywood flooring goes atop all this and traps the PEX in the grooves so it can help transfer the heat to the vinyl finish floor. 
Simple to install and use and provides THE best heating of a home we know of.  My toes are tingling in anticipation already!

IMG_20200113_174557These are the Supply and Return PEX lines as they enter and leave the Master Cabin into the Basement where they connect to the little circulation pump and in-floor water manifold.
IMG_20200117_110601More of Cihan’s pump mounting.  This is one of the circulation pump for the Webasto BlueCool chiller.  This is located under the workbench on your Right as you enter the Workshop from the Swim Platform.
IMG_20200117_110557If you were wondering what that wood disc is in the photo above it is this mock up of the 75L/20USG IsoTherm Calorifier which is essentially our Hot Water Tank. 
IMG_20200117_110550The real unit has not yet arrived so we’ve been using this wood mock up to position it under the Stbd/Right side Workbench.

Chiller on the Workbench above, Watermaker in front, water pressure pumps in front of Calorifier and Day Tank at the far end.
IMG_20200116_141251Okan seen here along with Cihan and Nihat have fabricated this hanging mount setup to tuck the Calorifier nicely up out of the way and with no danger of any water reaching it from the shelf below.
IMG_20200113_121053Last but not least for this week, Cihan is also responsible for plumbing the Webasto Air Handlers which have either chilled or hot water piped to them with a large fan blowing air through the liquid to air heat exchanger, like the radiator in your car, which then flows through air ducts to warm up or cool down the room.

Yigit seems to have Cihan scratching his head as we work through the best locations for the two air handlers up here in the SuperSalon.

IMG_20200113_121046We decided the one on the Stbd/Right side will work best here in the big area created by the side decks outside those big picture windows.  This still allows me plenty of room to be able to get inside this area through this big opening behind the Dinette seat whenever I need to service or work on any of the plumbing or wiring running through this area.


IMG_20200113_174820There was a LOT of progress with the electrical systems onboard Möbius this week and Hilmi and his team were very busy.

Can you guess what this example of their work is?
IMG_20200113_174829Help if I show you where those Red & Black cables lead to next?
IMG_20200114_130731Correct!  These are the 6mm2 / 10 AWG cables connecting the 14 Solar Panels to the 14 MPPT SmartSolar controllers in the Basement.  The cables run through this welded in place penetration and will be sealed with special class rated watertight foam just before we launch.  Cables then run along the upper roof area as in the first photo and then down through the flexible conduit in the I-beam window mullions and down into the Basement.
PH Vent Tunnel under solar panelsThe cables in the photo above will soon plug into the three 320W panels that lay on that hinged frame atop the front roof area of the Pilot House in front of the SkyBridge.  When we are anchored, this Solar Panel filled frame will be raised to be horizontal using the hinge on the edge along the SkyBridge window glass to create a massive wind tunnel bringing fresh air through that large vent you see to the left of the wiring in the photo above.
IMG_20200114_161822Click to enlarge this (or any other) photo and see if you can find the hidden Hilmi?

On the Right you can see the Red & Black solar cables he is running down through the conduit in the window mullions and then down into the Basement.
IMG_20200115_102229Having 14 Solar Panels in three different banks up on top and all connected to their own MPPT controller results in seeing these Red & Black cables everywhere you looked this week.  Such as these ones laying on the Galley countertops by the stairs up to the Aft Deck.
IMG_20200115_102254And these ones over on the Starboard/Right side ……..
IMG_20200115_132606 ……….. and these ones coming down from the Arch into the ceiling of the Guest Cabin and running forward into the Basement.

IMG_20200116_120509This is the penetration tube through the ceiling where these Solar Cables exit out the bottom of the Arch tubes and then run along the White cable trays you can see in the background here. 
IMG_20200116_120616Peeking through the oval penetration tube before the cables went in, you can see the base of one of the Arch tubes above and the slot through which the cables run.

And of course EVERYTHING insulated with at least 50mm/2” of the ubiquitous Black EPDM foam.
IMG_20200116_121422Similar oval AL penetration tubes in the SuperSalon floor/Basement ceiling are filling up with all the cables which need to run In/Out of the Basement which is Grand Central for …..
XPM Electrical System …….  our Electrical System.
IMG_20200115_144919This is what Grand Central Electrical Station looked like early in the week as they ran the Solar Cables and started to build the “Blue Wall” that where most of the bright Blue Victron boxes will mount.
IMG_20200115_102200One of the primary reasons we designed the XPM78 with this cavernous Basement area which is 1.2m / 4’ high running under the entire area of the SuperSalon floor, is to provide plenty of room for mounting most of the Electrical System components. 
One of the great benefits of building in aluminium is that we can easily weld in walls such as this one they are building overtop of the two big House Battery Banks that you see Hilmi on the Right standing in.

IMG_20200116_120728And the flood of Victron Blue boxes begins!

Victron 120/240V Isolation Transformer on the Left for the rare occasions when we have shore power.
IMG_20200116_120935Two Victron MultiPlus 120V 3000W 70A Inverter/Chargers in front on the far Right

As you can see this open mounting system provides lots of room for spacing each of these high heat producing devices well apart from each other and providing plenty of air flow around all six sides of each box.
IMG_20200116_120821Here is a shot of two of the three big Victron MultiPlus 240V 5000W 120A Inverter/Chargers on the other side of the wall.

Each one of these devices has its own thermostatically controlled fan pulling air in from the bottom and out through those two slots on each side and same on the back.  The whole Basement is similarly ventilated with thermostatically controlled fans to ensure that all the Basement residents keep their cool which is eXtremely important as heat dramatically and negatively affects their performance and they will shut down all together if they get too hot as many other boat builders and owners have discovered the hard way.

More Blue Boxes will be moving into this neighborhood soon as will the central DC and AC Distribution Panels with their respective high amp switches, fuses and circuit breakers.

IMG_20200115_153320On the other side of the mounting wall above we are also using the WT Bulkhead just in front of it to weld in these five black rubber covered AL brackets for an additional mounting surface for all 14 of the Victron 100/20 SmartSolar MPPT controllers and their junction box.  With each Solar Panel having its own dedicated MPPT controller keeps each panel independent from the others to minimize the effects of shading on any one panel and maximise overall solar output.
IMG_20200115_144955A simple AL plate provides both some protection for some of the many bilge pump lines running behind it and a large open surface for easy mounting and future access to all the MPPT controllers and junction box.  This AL plate is not only the perfect surface for easy mounting it serves double duty as we often do by providing a giant heat sink for all the heat coming from the heat sinks in each MPPT controller.
IMG_20200116_180706A justifiably happy Hilmi with his handiwork surrounding him as he puts in all three of the 240V MultiPlus Inverter/Chargers on the Right and begins mounting the top row of the smaller SmartSolar MPPT Controllers on the plate on the Left.
IMG_20200118_12305912 of the 14 MPPT controllers now mounted with their accompanying cable trays ready to receive their respective Red & Black Solar Cables and then the cabling to connect the output from each MPPT controller to the central bus bars and circuits breakers in the junction box in the middle.
IMG_20200118_123112Maybe we will call this Blues Ville?  But trust me, I will be singing anything but the Blues when I’m working in this area over the years and have this glorious amount of space and easy access to every hose, wire and device. 
My fellow boat owners will appreciate just how rare and precious this is.  It also adds to very real benefits of faster installation time, reduced maintenance time and costs, better cooling, easy spotting of problems, leaks, etc.  What’s not to love?


IMG_20200114_102313The Alucobond Brothers, aka Yigit and Okan finished fitting the aluminium/composite AlucoBond sheets that cover all the EPDM foam insulation in the walls and ceilings of the Workshop and Engine Room.  Once they are all fitted they will be taken out while they finish putting in penetrations and other work in the ER & Workshop so they are using sprung in place plywood sticks to hold the ceiling panels in place for now.
IMG_20200114_103703As we showed last week, one of the great features of using AlucoBond is that you can put in a small V-shaped kerf on the back side and then bend the board along that line to create a vey smooth and strong bend of whatever angle you need.  So that is how they have bent this ceiling panel to wrap around the huge ER Hatch opening in the Aft Deck.  Makes for a very strong, safe and easy to clean surface throughout notoriously difficult to keep clean ER walls in most boats.


IMG_20200116_102750The Rudder received lots of TLC from the team this week as they installed it with its Jefa roller bearings and began the critical fitting of the Rudder Post and Tiller Arm up in the Workshop.
IMG_20200116_102812These hand cranked jacks supported the large heavy Rudder and enabled precise vertical adjustment of the position of the Rudder Post to the Tiller Arm and Steering gear.
IMG_20200116_102856Which is what is going on here with the humongous 127mm/5” solid AL Rudder Post now in position supported top and bottom by Jefa Self Aligning roller bearings which you saw a few weeks ago. 
The largest White flange here is the top of the Upper Jefa self aligning roller bearing where its lip sits atop the machined edge of the welded in Rudder Tube.  On top of that is a special White ball bearing ring Jefa provided to look after the vertical thrust forces.  Then the Black anodised AL collar will slide all the way down and be locked in place to the Rudder Post with the SS set screws you can see on its outer circumference. 

IMG_20200116_150043For the coup de grâce the solid CNC machined AL Tiller Arm is set in place on the Rudder Post and setting atop the Black collar to lock the whole assembly in place.

IMG_20200116_150449The two halves of the Tiller Arm are clamped in place with the SS key inside.

The two vertical pins are upside down here but they are where the Heim joints on the ends of the hydraulic Kobelt cylinders will attach.
IMG_20200116_110605Down on the bottom end where the Rudder Post fits into the Rudder Tube, there is a 6cm/2.5” thick Delrin bushing to provide a smooth slippery surface whenever forces want to push the rudder upwards.
Turning Delring rudder bushingA simple job for our in-house machine shop to turn from this big block of White Delrin.
Delrin rudder bushingAnd create this White Beauty to fit snuggly into the Rudder Tube.  There will be two large radius grooves cut into the outer circumference to provide a space for the special adhesive that will be pumped through small holes drilled through the 10mm / 3/8” thick AL walls of the Rudder Tube.

The lower Jefa roller bearing rests atop this Delfin bushing and is adhered to the Rudder Tube with the same method of pumped in adhesive which once set makes for a solid single assembly.
IMG_20200116_175354Now we need to be able to rotate that massive Rudder through its full 90 degrees of lock to lock travel so we unboxed one of the two 24V Kobelt Accu-Steer HPU400 Hydraulic Power Units and double checked all the geometry and dimensions for mounting them on a shelf above the top of the Rudder Post.  Lots more details on that as the installation happens next week.


Guest Cabin V2 Fwd Stbd cornerAs a reminder, here is how the Guest Cabin is laid out.  The couch pulls out to make a Queen bed and the Pullman Berth folds down from the upper Right area to make a good adult sized single bed.  Plenty of bookshelves and storage when Captain Christine is using this for her Office with her desk along the Aft wall on the far Right with plenty of storage areas built into its far end.

IMG_20200114_102332In spite of appearances to the contrary on board, the cabinetry for the Guest Cabin is coming along wonderfully with Omer over in Naval’s Cabinetry Shop next door so let’s go check in with Omer.
IMG_20200114_103814_MPHere is is working on the Desktop in Christine’s Office in the Guest Cabin.   The rectangular opening will provide access to the Webasto Air Handler that mounts inside a cabinet at the far end of Christine’s desk up against the Stbd/Right hull.
IMG_20200114_103826To keep this super solid and yet light he has built this with these boxed frames laminated from that same super lightweight marine plywood made from Poplar. Once both top and bottom are skinned with 16mm plywood this lightweight assembly becomes incredibly solid and stays perfectly flat.
IMG_20200114_103904_MPIn the foreground is the cabinet riser that sits atop the outboard end of Christine’s Desk and covers up that rectangular access hatch to the Air Handler which Omer is working on in the background.  Not something I should need to access very often but we put a high value on easy access so we design in features such as this.
IMG_20200115_102507Of course all the lower surfaces are coated with Ro$ewood and Omer is an true artisan and craftsman when it comes to creating works of art with his veneering skills.  This starts with him selecting the just right set of matching flitches of Rosewood veneer, cutting and matching the pieces together to create the most beautiful flow of the swirling grain and then taping these in place on the outer surface.
IMG_20200115_133044Once ready, the bottom surface is coated with thermal reacting glue and put into the heated veneer press to clamp the veneer to the underlying plywood and then back to his workbench as you see here for machining the solid wood edges and joinery.
IMG_20200117_110841Features such as grooves for the indirect LED floor lighting and my infamous Blue Horizon Line need are machined next with tools such as this small handheld router.
IMG_20200117_144118These are all parts which make up the settee in the Guest Cabin which pulls out into a Queen Bed.  The pull out end of the bed is on the far Left here and the interlocking slats which allow the bottom of the couch/bed to slide in and out are stacked on the Right. 

I have used this sliding “fingers” style in several beds I’ve made for my homes over the years and it works extremely well and lasts forever so seemed to be the just right choice for this multipurpose couch and bed onboard Möbius.


IMG_20200113_174458Back onboard XPM78-01 Omur and his team have gone on to the next stage for this room where they are now bringing all the cabinetry components back from the Finishing Shop with their expertly applied 5 coats of Poly Urethan varnish and being assembled and attached to their respective foundations on the floor, ceiling and walls.
03This early rendering of the Master Cabin will help you visualise this Master Cabin.  You are standing in the entryway door looking diagonally forward to the glass walled Shower in the far Port/Left side hull.
02Standing in the shower looking Aft along that same diagonal you see the raised King Bed with all its drawer storage underneath, closets and bureau of drawers on the Left and entry door in the far Left corner leading up the stairs to the SuperSalon.
IMG_20200114_103150Celal has just finished setting the hanging closet at the bottom of those stairs.
IMG_20200114_161643Omur and Selim now begin to put all the jig saw pieces together as they assemble all the other Master Cabin cabinetry.  They have the Bureau of Drawers in place on the far Right and are here working on the bottom of the closet cabinetry that goes in front of it.
IMG_20200115_102114_MPDoesn’t take them long to put the puzzle pieces back together but it is a bit tricky sliding this into place on its base.
IMG_20200115_132629But that too goes well as they fit the bottoms of the vertical dividers into their respective set of biscuits which have been inserted into the base of the closets.
IMG_20200115_144309_MPThe module for the stacked Washer & Dryer slides in next.
IMG_20200116_110054_MPHorizontal divider where the ubiquitous Rosewood handhold and Blue Horizon Line will attach is set into its slots.
IMG_20200116_110342Working his way counter clockwise around the room Omur preps the foundations for the Vanity Sink that sets up against the WT Bulkhead with the Forepeak locker on the other side.
IMG_20200116_121517Next set of puzzle pieces that make up the Vanity Sink base cabinet and upper Medicine Cabinet.
IMG_20200116_181000_MPBoth of those cabinets now in place and Omur is taping off the corner surfaces to protect them from the squeeze out of the sealant between them for any spills around the sink which rests atop that Ro$ewood surface.
Vanity Sink MasterCarcasses all in place now ready for their drawers and doors and …….

Turquoise oval sink ……… just to wet your appetite for what is to come this is the sink that will be mounted in there.  Just wait till you see what this looks like in contrast to all its Rosewood and leather surroundings!
IMG_20200117_173521On to the next set of cabinetry, the big Master Bed platform, flipped on its side here starts to go together.
IMG_20200118_104717Headboard rises all the way up to the ceiling where there will be a large overhead dropped ceiling box that you’ll see next week.  However you can already get a sense of how much storage space there is under the bed alone. 
IMG_20200118_104749Looking aft overtop the bed shows how some of the storage will be in large open spaces such as the Birch lined one on the Left and then much more in the twelve drawers which go into the Rosewood lined cabinets at the base of the bed facing the Shower and along the sides of the walkway past the bed on the Right.
LED floor lightingLeaving you with one of the thousands of little details of the interior and evidence of Hilmi’s handiwork, this is the 24V power wires for the indirect floor lighting from a continuous strip of LED lights set into a groove in the underside of the overhang of the cabinets from the toe kick frame.

And th-thh-thhhhhh That’s all for this week folks!

Hope you enjoyed this latest update on the building of the Good Ship Möbius aka XPM78-01.  We sure appreciate having you join us and we are particularly grateful for all the comments, suggestions and questions you send in so don’t be shy and please add your latest contributions in the “Join the Discussion” box below.

Captain Christine will be back on Thursday night so just four more sleeps for me to wait!  Not that I’m keeping track or anything.

Oh, and just to let you know in case it delays next week’s update post, we are going to fly to Dusseldorf for the huge “Das Boot” boat show there next weekend.  So if any of you happen to be attending this big event please do be in touch and we can try to meet up.

We decided to go partly as a treat to each other for a break from all the non-stop action here and also to pick up more parts and equipment for Möbius to bring back with us on the plane.  We get back on Monday afternoon so we’ll show you what new arrivals we have brought back with us and have Captain Christine unbox those Helm Chairs for you so do stay tuned for all that and more.

Off and Running!  First Week of New Year/Decade: XPM78-01 Möbius Weekly Update

Off and Running! First Week of New Year/Decade: XPM78-01 Möbius Weekly Update

First week of the year and we have 2020 off to a great start with all the progress on Möbius this week.  I just got back from taking Christine out to the airport this morning as she flies back to Florida to finish her 100 Ton Captains License testing and start her year off right with the gift of some Gramma time as well as seeing family and friends in the Fort Lauderdale area.  And of course she left with four empty suitcases to fill up with the latest flurry of parts and equipment to bring back with her when she returns on the 23rd.  She’s taken to calling herself Möbius’ Mule with all the bits of kit she has been transporting through airports the past two years.

IMG_20200111_121229We have been having spectacular Winter weather here in Antalya.  Crystal clear skies make for colder temps in the mornings and evenings, down to 1C/34F at 6am when we left to drive to the airport, but it was 15C/60F by noon with views of our surrounding mountains like this and full moonrises that have been magical.

With that prelude let’s go check up on Team Möbius at Naval Yachts this first week of 2020, Jan 6-10.


I will have the “Sparkies”, Hilmi and his electrical assistants start us off this week.

IMG_20200106_111139_MPYou may recall a similar shot last week as Nihat continued to work on getting the integral battery compartments ready for the 18 4V Carbon Foam batteries which will make up our 1350Ah @24V House Battery Bank which is the heart of the whole electric system on Möbius.

Here, Nihat is cutting in the openings where the huge 120mm2 / 4/000 AWG cables that connect the three individual 24V banks to the main DC bus bars and high amp distribution panel.  That Distribution Panel will set in the rectangle just above Nihat’s head on the left of this picture and I’ll show and explain more about that once that is being installed.

IMG_20200106_111715The in house composite fabrication department whipped up these two containment boxes for the two battery compartments and dropped them off in the Galley. 
The batteries fit snuggly into these boxes so we subsequently decided to cut them way down so they are only about 100mm/4” high to act as Battery Containment Trays rather than full height battery boxes.  We did this to increase the air circulation around all the batteries to be sure that we can keep the heat down if it were to build up with high rates of charge in tropical climates.  Even though the probability of these fully sealed Carbon Foam batteries ever allowing any of their internal fluids escape is eXtremely small, containment trays are an AYBC requirement and just a smart thing to do.

IMG_20200107_105110These Battery Containment Trays are a snug fit inside the frame on the Battery Compartment floors so their bottoms are held tightly in place and can’t move.  You can also see the slot for the connecting cables to pass through that Nihat was cutting in the opening photo.
IMG_20200108_104607_MPCelal is a new addition to Team Möbius and he has been busy helping Hilmi, barely visible behind, install the Victron MultiPlus inverter/chargers and route all that big 120mm2/ 4/000 red and black cables.  For a sense of size of those integral Battery Compartments, Celal is standing in the middle one and you saw Nihat comfortably working inside the forward one in the opening photo.
IMG_20200109_112101Not the most exciting shot but the arrival of all the cabling for our 14 solar panels arrived this week and that’s very exciting. 
You can click to enlarge if you’d like to see the specs on this cable which reads:

Photovoltaic Cable H12222-K 1 x 6 mm2 1kV 90C

IMG_20200111_111839This is cable specifically designed for transmitting all the Watts of power from each panel with minimum voltage loss and able to take sustained UV and marine exposures.

MC4 connectors are used to join each cable to the solar panel cables and we run on positive and one negative lead from each panel down to the Basement where it connects to its own MPPT controller, Victron’s SmartSolar 100/30 MPPT controller.
IMG_20200109_181012_MPHilmi was also busy up on the Forepeak putting in cable trays and running the pair of large 120mm2 / 4/000 Red & Black cables which supply over 700 Amps of 24 volt power to the Distribution Panel in the Forepeak.
IMG_20200111_112610_MPOver on the far left side you can see the other cables for 220V AC and will also go into the Distribution Panel that will be on the far Right.  It will supply power for everything from the Maxwell VWC 4000 Windlass, Lewmar 65EST winch, Vetus Bow Thruster, Black & Gray Water pumps, lights on the Bow Mast and others.


Cihan was busy as usual with the many different systems requiring his plumbing skills so let’s check up on his progress.


Up in the Master Cabin you may recall he had previously mounted these two S bends drains for the Shower and the Head/Bathroom floor that feed into the new Whale IC Gulper drain pump system. 
IMG_20200106_112840However upon testing it we found that the height of the floor was going to be a bit too close to the top of the S-bends and we were concerned it would sometimes not flow well as the boat moved.
IMG_20200106_174235So Cihan quickly swapped them out for these simple elbows and the automatic water sensor in that yellow manifold against the hull on the left worked perfect every time and would pump water out as fast as we could pour it in from the bucket.

There is a one way valve at the diaphragm pump that is in the Forepeak which is on the other side of the WT Bulkhead at the end of the Master Cabin on the far right of these photos and this valve seals off the drain lines you see here so there is no concern about noise or smell.

IMG_20200108_104814_MPDown in the Basement Cihan continued plumbing the in-floor heating system.  Hot Supply water manifold is up at the top and colder white/blue manifold below.  He has finished plumbing the main Supply/Return lines on the right and has them all insulated in black EPDM to reduce heat loss as the water flows to and from the in-floor heating system from the DHW Domestic Hot Water system.
IMG_20200108_104831Now he needs to mount the three 2 speed Circulation Pumps, one for each Zone/Cabin’s loops of PEX in-floor tubing.

Cihan had previously fabricated the mounts for each pump and bolted them to the vertical frames of this WT Bulkhead with the Guest Cabin on the other side.
IMG_20200109_112953_MPEach pump has its own Hot Water line from the Supply manifold so they were plumbed next.  Third Supply line going in here.
IMG_20200109_113019Some of you inquired about the PPR type plumbing being used for all our potable/drinking water onboard and so I grabbed this action shot of Cihan and Celal using the thermal welding tool to join the PPR pipe to its fitting on the right. 
IMG_20200109_113011The aluminium arm extending out of the welding tool has two fittings on the end, the one on the right side slides into the female end of the fitting and the other fitting goes over the male end of the pipe on the left.  Wait a few seconds while the PPR melts then pull the tool out and slide the pipe into the fitting.  Done! 
IMG_20200109_135114Very different than with PVC piping which uses liquid glue to melt/weld the joints but same idea of welding the plastic parts together and creates a permanent leak free joint.

Close to finished now and ready for the Supply/Return PEX lines to be run from here to and from each in-floor heating zone which we should see happening next week.
IMG_20200109_180644However, does this drawing that just showed up in the Master Cabin help you figure out what DID happen this week?

Maybe this close up of the drawing will help?

Aha!  The drawing is Yiğit’s latest work of coming up with the ideal routing of the continuous loop of 15mm / 5/8” PEX tubing which has to wind its way through all the floor areas while carefully snaking around the tank access lids and furniture foundations. 
There is also a minimum bending radius of 6X the PEX tube diameter so 6 x 15 = 90mm/3.5” so Yigit used a 180mm circle to layout all each of the bends where the PEX turns around and doubles back.

Adding to the challenge, you also want the beginning Supply end of the PEX loop, which is in the Upper Left corner of the drawing, to go through the areas where you want the most heat and you want to have more tubing per square cm in these areas which in this case is the floor of the Shower and Head/Bathroom in the Upper Right.  I had mapped out the basic routes but it was quite the Tetris or Rubik’s Cube like puzzle for Yigit to solve.  As you can see he did so brilliantly as usual.

IMG_20200110_144700Once he had the route all figured out Yigit then printed out the centerline of this route in full size sheets and Omur and Selim are now carefully laying them out and taping them accurately in place on the rigid foam board floors. 
IMG_20200110_160522With the paper route lines all taped in place they are ready to start cutting the U-shaped grooves in the rigid foam floor boards with a small handheld router.
IMG_20200110_160545The foam board chips created with the high speed router bit makes quite a mess so Selim follows the router with the vacuum which made for a very clean operation and easy to follow the line with the router.
IMG_20200111_112100Here is where they left off by end of the day Friday.  They will finish the routing next week and line the grooves with aluminium foil tape to increase the radiation of the heat upward into the 10mm/ 3/8” plywood floor which will attach to the white epoxy perimeter foundations.


IMG_20200106_111315However Selim and Omur where mostly busy this past week with an even more exciting bit of progress as they completed the vacuum bag gluing of the Rosewood veneer to the Galley Garages you saw last week.
IMG_20200109_142751Here is a stack of our Ro$ewood veneer awaiting their turn to be carefully selected and taped into matching grain patterns for the lower half of the wall panels and other cabinetry throughout the boat.
IMG_20200109_142801Costly and time consuming in the eXtreme?  You bet but in our eyes and souls at least the beauty is even more eXtreme and something we will be looking at for decades to come so an easy to make investment decision for Christine and me. 

See what you think as you see the completed results in the coming weeks.
IMG_20200106_111503As you saw last week, all three sides of these Galley Garages, including their doors are laminated at the same time inside the vacuum bags and then they carefully cut through all the slots around each door.
IMG_20200108_144240_MPWith the doors released they can apply the Beechwood veneer to all the inner surfaces and route around all the solid Rosewood edges and fit them to each of their respective Garage openings.
IMG_20200107_105825Which is what Selim is doing here as I enlist his help to give you a bit of a preview of what’s to come from the work of these master craftsmen. 

IMG_20200107_105710As they create works of art like this.
IMG_20200107_105838And this.

Just wait till you see these swirling waves of grain patterns pop when they come out of the Finishing spray booth!
IMG_20200107_105524A justifiably proud Omur and Selim finish the final fitting and sanding so they can send this all up to the Finishing Department.
It was impossible to capture this whole four sided assembly of all the Galley Garages so I shot this short video scan to share this beauty with you a bit better.  Rosewood in Rotation if you will ………………………


Corridor workbench   StairsNot to be outdone, Omer was equally as busy singlehandedly doing all the cabinetry in the Guest Cabin and Corridor Workbench areas so let’s go check that out.

Looking forward along the Port/Left hull side where my Office/Workbench resides and the Guest Head/Bathroom on the Right.

** Note: the shower that would normally be in the bottom Right corner has been removed to show this view.
Entry to Guest Cabin Head ShowerSitting on my Office Workbench looking straight into the Entryway to the Guest Cabin and the pull out couch on the far Starboard/Right side.  Stairs up to the SuperSalon on the Left, WT door into the Engine Room & Workshop on the Right.   On the Left corner of the Entryway is the Guest Head and Shower on the Right.
IMG_20200106_105954Back to reality, Omer has the double duty “Swiss Door” all fitted with its surrounding frame for the Guest Head/Bathroom.  Continuing the Blue Horizon Line theme that runs throughout all the interior spaces, the top half of this and all other vertical panels will have light Green/Gray leather covered removable panels set into them. 

If you look closely (click to enlarge any photo) and in the render above you can see where the leather panel will go on the wall to your Right as you go up the stairs to the SuperSalon.
IMG_20200107_110057Omer had taken that door back to his workbench in the Cabinetry Shop to finish the solid Rosewood edging and finish prepping this door to head over to the Finishing Department. 
IMG_20200107_110120You can see how these doors are made to be very solid yet very light with their foam filled cavity cores.
Guest Cabin 1This is an approximation of what the cabinetry inside the Guest Cabin.  Christine’s Office on the Right, Pullman Berth on the far Stbd/Right side hull, pull out couch/Queen bed below and L-shaped Bookshelf wrapping around the Left corner.
IMG_20200109_112726However here’s what it looks like right now!  Omer has been taking all the cabinetry back to his workbench to do the final preparation before he sends it up the boys in the Finishing Department.
IMG_20200108_105122Seen upside down, we are looking in from the end of that Bookshelf which will soon have a panel set into it where the Pullman Berth begins, Omer is finish sanding the solid Rosewood edging that runs around the perimeter.
IMG_20200107_143256Bookcase has now been flipped right side up and in the foreground you can see that Omer has started to build the dividers and shelves which turn this into a very functional bookcase.
IMG_20200107_143307These dividers and middle shelf have solid Rosewood outer edges with White interior surfaces.  A thin layer of phenolic has been laminated onto all these white surfaces to provide the just right surface for the White lacquer to form a perfect flat and smooth surface.


IMG_20200106_105856_MPSwitching from Rosewood to Aluminium now, Uğur, Okan and Nihat very busy making their typical great progress this past week which for them was mostly all about covering all the interior wall and ceiling surfaces in the Workshop and Engine Room with AlucoBond which you saw them starting to do last week.
IMG_20200106_112732One of the features of AlucoBond which makes it the ideal choice for all these removable wall and ceiling surfaces is that it can be easily bent to form smooth strong corners with a very safe radiused edge. 
IMG_20200106_112727If you look closely at the bend on the bottom right of the photo above you can see how a small kerf has been cut not quite all the way through the 5mm / 3/16” AlucoBond to allow them to hand form these bends.
IMG_20200107_104619Which is how they are building these corner transitions between the wall and ceiling panels in the workshop.  Stbd/Right side Workshop here.
IMG_20200109_113421Here is the Port/Left side looking from floor level by the WT door leading into the Corridor and Guest Cabin areas.  Facing Aft here along the AL workbenches.  HazMat locker on the far Right end.
IMG_20200109_113433Stepping forward a few steps to look across to the Aft Stbd corner and the WT door out to the Swim Platform.  Uğur is kneeling on the Rudder shelf and you can see the Rudder post tube on center behind him.
IMG_20200110_103339Stepped corner details just inside the Swim Platform door.
IMG_20200107_174012Webasto BlueCool V-Series chiller has been mounted to the built in AL shelving.
IMG_20200107_174021All equipment is mounted with appropriate types of vibration reduction soft mounts such as these.
IMG_20200110_160718Next up on the AlucoBond list is the Engine Room.
IMG_20200110_160738So Uğur and Nihat have installed the L-bar frames and they have started cutting panels to fasten to them.
Well, as you have seen the first week of 2020 has all of us on Team Möbius off to a good start as we all push ourselves for the final leg of this part of the adventure leading up to Launch Day!  That is still several months off but will be as soon as we can possibly make it.  Be sure to subscribe by putting your Email into the “Subscribe” box on the upper Left corner of every blog page so that you don’t miss any of these weekly updates and you can join us on this leg of the Project Goldilocks adventure.

New Year – New Boat–New Baby?  Progress Update XPM78-01 Möbius Dec 30-Jan 03, 2020

New Year – New Boat–New Baby? Progress Update XPM78-01 Möbius Dec 30-Jan 03, 2020

First and foremost Christine and I, along with everyone on Team Möbius here at Naval Yachts, we want to wish all of you a VERY Happy New Year and the hopes that 2020 will be the best circumnavigation of the sun for all of us.  It is shaping up to be a VERY good year for us as we all work relentlessly towards launching the very first XPM and our new home Möbius in the next few months. 

W&C New Years bow shot KissingWhile it does often remind me of that saying “when you are up to your neck in alligators, it is hard to remember you are there to drain the swamp”, this adventure continues to be an awemazing experience for us and very much remains a labour of love and combined work of art and engineering. 

And while we gladly chose to use a “pay it forward” approach to this blog and do our best to openly share all aspects of turning our vision into the reality of the very best Goldilocks just right, just for us boat, we REALLY appreciate the thousands of you who chose to subscribe and join us on this grand adventure.  It means a great deal to us and you add a huge value to the whole experience so a very heartfelt THANK YOU! going out to all of you as we get this new year and this new decade started.

Click to enlarge the photo to see the first of many New Year’s Eve kisses standing in front of our already beloved Möbius with some of the crates in front that are piling up as more and more new equipment arrives. 

When you are married to your best friend and your Captain who also happens to be the most Beautiful person you know, you take EVERY chance you get to kiss her!

IMG_20191229_175105Naval Yachts sent everyone home at noon on New Year’s Eve and reopened on Jan 2nd so we all enjoyed a 3.5 day work week.  Christine and I enjoyed the chance to have time together to engage in deeper discussions about the thousands of decisions needing to be made and new learning about such scintillating topics as NMEA 2000 network topologies so we spent much of our “time off” comfortably sitting in front of our large 50” monitor at home to have all our reference info easily displayed for both of us to see, point to and modify.  Different strokes for different folks right and being the crazy couple we are, this was great fun for us.

In the foreground you can see that Christine is getting lots of help from Commodore Barney aka the Yorkshire Terror and if you click to enlarge and look closely on the couch behind Christine’s back you can just make out Ruby the Wonderdog who is also supervising her work.

IMG_20200104_173229New Year’s Day dawned with clear blue skies and sun to light up the mountains which surround us and showed off their freshly snow covered tops.
IMG_20200104_173247Not what many people imagine when they think of Turkey but we love this country and even more so her people, food and sights.  We are very anxious to move aboard Möbius and get back to life at sea but we will also miss this special place that has been our home based for over two years and our Goldilocks location to built our Goldilocks boat; just right, just for us.
IMG_20200101_170448_MPWe did take a bit of time off on New Year’s Day to go for a long walk to some of our many favorite spots along the Med coastline that is only a few blocks away and a large newly constructed park along both sides of the new inlet they are putting in which will eventually have a large superyacht marina in the waters you can see here.
IMG_20200101_164245If we were to have any regrets it would only be that we don’t get or take enough time to enjoy our incredible surroundings every day.  This spot along a beachfront walk is at the very far West end of Antalya and only a few blocks from both our apartment and Naval Yachts in the Antalya Free Zone. 

In the background you can see how the city of Antalya stretches along the crescent coastline to that point you can see in the distance in the upper middle of this photo.

All very beautiful and fun BUT even we couldn’t top the news the next day that Naval Yachts had expanded VERY significantly with the arrival of the very first girl in the Dinc family for several generations.

Ida Dinc   Mom 01-02-2020Meet the newest member of the Dinc family; Okyanus Ida, born Jan 02, 2020 at 2.65kg.  Baby and Mom both doing great.  Dad Baris, we’re not so sure?! Smile

Welcome to this most awemazing world Okyanus Ida!  Oh the places you will go and the Love you will know.

Well, I certainly can’t top that but let’s get back to boat building shall we?


IMG_20200102_152757I’ll start with a brief update on what the Sparkies or electricians have been up to this week and see if you can guess what Hilmi, our electrician seen here driving the forklift, is moving up onto the front deck of Möbius?

Hint, they are VERY heavy!
IMG_20200103_104728Many of you will have guessed correctly that these are the two pallets full of our batteries.  I know many of you have been patiently awaiting my Tech Talk discussing our new battery choice and the details of our whole DC system and I’m afraid I need to test your patience a bit longer as I just have not had the time to finish that article, but it should be done and posted within the next week or so.
Untitled-1The not so well kept secret many of you have already figured out is that we changed the battery type we are using for both the 24V @ 1350Ah House Battery Banks and the Gardner Start Batteries from OPzV Gel type to Microcell Carbon Foam batteries by FireFly International.

XPM Electrical System

This graphic which you’ve seen in previous posts will give you the high level view of the overall Electrical System on XPM78-01 and I’ll be doing a much deeper dive into these components in future posts.
IMG_20200103_104603Back onboard, Nihat is working on the cross members for what we are calling “the Victron Wall” as it will soon have all the big blue Victron boxes mounted which include:

  • 3 Multi-Plus 5kW 220V Inverter 120A Chargers
  • 2 Multi-Plus 3kW 120V Inverter 70A Chargers
  • Isolation Transformer
  • Centaur 90-265V 50/60Hz “World” 24V @ 60A charger
  • 2 Orion DC-DC 24-12V @ 7A  converters
  • 14 100/30 MPPT Controllers

IMG_20200103_125012With apologies for the poor quality this photo of the sketch onboard will show you the basic layout for this wall and some of its components.  The main high amp DC circuit distribution panel will be in the middle flanked by the Victron components. 

The 14 MPPT Controllers will mount on the other side along with several other DC related equipment.
IMG_20200103_124553One of the many advantages of building wtih aluminium and having this cavernous Basement area under the whole SuperSalon floor is that we can put in these “walls” anywhere we like to create an enormous amount of surface area for mounting equipment. 

Having so much area means we can space the equipment out to make access eXtremely easy and in the case of heat producing components like these Victron units, keep them much better cooled. 

The whole Basement is also fully ventilated wtih both passive and active fan assisted ventilation which is separate from the same level of ventilation in the integral  Battery Boxes which you can see on the Right.

IMG_20200103_171724_MPJust about done, Hilmi  with his back to us helps hold in the flatbar cross member that will soon be home to some of the 14 MPPT controllers.


Cihan was moving too fast for me to catch up with this week I only caught him in this one shot to show you some of his latest handiwork with the plumbing on Möbius.  This shot is taken inside the Engine Room looking at the forward Starboard/Right corner. 


Here he is connecting one of the water supply hoses to fill the Starboard ER water tank.  Intake Sea Chest is right behind him and you can see the white perforated tray running across the WT Bulkhead which will soon fill up with more water hoses.

Nogva CPP Servo Gearbox in the bottom Right and Mr. Gee our Gardner 6LXB will soon be bolted in front.

Whale Gulper Grey IC box photoEvidence of Cihan’s work is also evident up in the Master and I think some of you will be quite interested to some of you how we are going to handle draining shower and floor in the Master Cabin so let’s take a look.  We are going to try out this relatively new Whale Gulper IC drain pump system.  With our floors sitting on top of all the integral fuel/water tanks it is challenging to be able to use gravity to drain the water from the floor of the shower and the Head and this Whale IC system is the perfect solution.

If you click to enlarge the photo (works on all photos BTW), you can see the diagrams showing how this works.

Whale Gulper Grey IC components photoThis model handles two drains by having each drain hose go straight into the round yellow 2 way manifold you see on the right.  Inside is a small electronic water sensor which is the IC Intelligent Control in the name and when it senses water it sends the signal to the Gulper diaphragm pump on the left to turn on and pump the water out of the manifold and into either the Grey Water holding tank or Sea Chest.  When there is no water in the manifold sensor it shuts the pump off.

IMG_20200103_125154Here is what the drain looks like mocked up on the floor in the Master Cabin Shower.  There is a matching one off to the Right just out of this picture which will drain the floor in the adjoining Head/Bathroom.  A hose will connect the Yellow manifold to the horizontal Grey fitting coming from the shower floor.

You can see the Yellow 2 way manifold hiding  in the center background and on the Left atop the White S trap is where the drain in the shower floor will be.  Floor height is raised in the Heads to provide enough drop to gravity feed the manifold.  The pump will mount on the other side of the WT Bulkhead in the Forepeak so the drain will be completely silent.

All very simple and automatic compared to the more common marine solution of having to turn on a pump manually or building in a shower sump box with a float switch and centrifugal pump which typically clogs very easily and requires frequent maintenance.  Music to my ears and one of the XPM theme songs; Low Maintenance!


IMG_20191230_163334Uğur, Okan and Nihat who is pictured here, continued where they left off last week putting in the grid for the removable Alucobond sheeting on the walls and ceilings of the Workshop and ER.  You can see the aluminium L-bars in the aft most end of the Workshop are now in place and ready to receive the Alucobond sheets.

Nihat is also putting in some of the last bits of EPDM insulation foam on the Aft Transom wall where Cihan will soon be installing the two shelves for the Accu-Steer HPU400 Steering Pumps to mount directly overtop of the Rudder Post and Tiller Arm Head which sit right about where Nihat’s knee is.

IMG_20191230_163338Rotating about 90 degrees to the Left looking at the Starboard/Right side of the hull we see that the L-bar mounts are in place and ready for the Alucobond. 

The Black/Yellow tool box and Blue bucket are setting atop the AL Workbench and cable trays on the ceiling and Port side wall are starting to fill up with electrical cable and plumbing.

IMG_20191230_125355Pardon the poor focus but this is the system we will use to fasten all the Alucobond panels to the L-bar.  Self drilling and tapping screws which have that special brass washer that is threaded on the outside circumference and the chrome cap is threaded on top.
IMG_20191230_125440Looks like this all assembled and makes for a nice finished look.

Whenever I want to remove one of these panels to access what’s behind I just twist off the caps and undo the screws.  KISS, Keep it Simple and Safe.



I tend to save the Cabinetry Team’s work for the end because otherwise their work with this Rosewood tends to steal the show and with doors like this make that quite easy to understand.

But now let’s go check in with Omer, Omur and Selim and see what’s new this week.
IMG_20191230_114509Omer is in charge of the cabinetry in the Guest Cabin, Head, Shower and Corridor Office and we find him working on that “Swiss Door” we showed you last week when he was fitting it into place in the door frames onboard Möbius.  Now he is trimming the solid edges with their radiused corners and rabbits/grooves for door seals.
Swiss Door exampleThere are French Doors, Dutch Doors, Pocket Doors and so we’ve come up with this Swiss Door moniker for the two doors we’ve designed into the boat, one in the Guest Cabin and another in the Main Cabin.  Both of ours are off the boat right now and this type of door is not well known but I was able to find this shot online that shows how they work.  A single door which swings shut on two different doorways.

We figured these doors are a bit like a multi purpose Swiss Army knife and hence Swiss Door! 

We had one on our former sailboat “Learnativity”, the source of a lot of ideas we are bringing with us onto Möbius.  They eliminate one or more doors so a big weight savings and cleans up areas on the boat where you might have multiple doors all competing for space and swing room.  More KISS

IMG_20191230_163507On Möbius here is what that door looks like looking out through the entranceway out of the Guest Cabin into the Corridor where my “Clean Workbench” office runs along the Port/Left hull.  Swiss Door on the Right now closing off the Head/Bathroom, Shower on the Left.  Door is hinged on the far side nearest the Corridor.
IMG_20191230_163636Stepping out into the Corridor and looking forward to the stairs that lead up to the SuperSalon shows that same Swiss Door with its hinges about where the blue tape is.  Your imagination shouldn’t have too much trouble seeing how it will swing open from here and shut against the door jamb in the foreground when our Guests would like some privacy or when Christine is working at her Office in there and wants to keep her pesky husband out!
IMG_20200103_125913Back in the Cabinetry shop these are some of those door frames and door jambs ready to be glued up and finished.
IMG_20200103_125919Laminated cores wrapped in Rosewood veneer and solid edges makes these both super strong and beautiful.  Not that I’m biased or anything.
Guest Cabin V2 Fwd Stbd cornerOmer also worked on finishing up the Pullman Berth inside the Guest Cabin and for orientation here is a rough rendering of what the Guest Cabin looks like with the Pullman Berth hinging out of the Upper Right side of the back wall which runs along the Starboard/Right hull.  It folds up to be out of the way as it is here and then easily folds down like Pullman Berths on trains and ships or a bit like a Murphy  bed in homes.
IMG_20200102_163107Here Omer is working on the single bed sized frame that folds down to make the Pullman Berth. 
IMG_20191231_114700_MPFlipped over to show how the mattress will be fit inside this frame and stay secure as it is folded up and down.
IMG_20191231_114712Before he glued it up, Omer took time to show this good example of how the biscuit joints work to create super strong glued joints.

But what are those five holes for???
IMG_20191231_114019Aha!  Yunus, our Stainless Steel guru has whipped up these SS hinges for the Pullman.
IMG_20191231_114058One mounted in the lower sides of the outer cabinet which the Pullman Berth frame sits inside of.

Vent grills on the top are where the cold/hot air will come into the Guest Cabin/Office.
IMG_20200103_105537With the Pullman bed frame all glued up and sanded, Omer added these strips of Beech to provide that thin gap running inside the corner between the strips and the frame sides.  This is where they will tuck the leather that wraps around the outer surfaces of the Pullman and are pulled tight.  More on that in coming weeks as the interior finishes begin to be added.


MOBIUS_SALOON_RENDER (1)Not to be outdone, Omur and Selim were also hard at work on the cabinetry for what we call the Galley Garages that set atop all the Turquoise granite countertops as you can see rendered here.

Dinette or Settee in the foreground with Galley behind on the Left side, entry door and stairs down from the Aft Deck on the far Right side blocked a bit by the tall twin fridge cabinets and Lounge on the far Right.

MOBIUS_SALOON_RENDER (4)This overhead shot puts the whole SuperSalon into perspective.  Stairs down from the Aft Deck and second set down to the Corridor and Guest Cabin in the bottom Right.  Continuing counter clockwise; Lounge area with Eames chairs, Main Helm chair center Left, stairs down to Master Cabin upper Left, Dinette/Settee, Galley in upper Right corner with Garages wrapping around all the countertops.

IMG_20191230_114618Omur checking the fit of the Garage doors on the Garages that run along the Stbd/Right side windows as prepares for laminating the Rosewood veneer to finish these off.
IMG_20191230_114647Same set of Garages seen from the back edges that will run along the 28 mm glass side Pilot House windows.  The cut-out where his hand is are where the vertical aluminium I-beam frames and window mullions set.
IMG_20191230_114731Selim has been busy similarly finishing off this set of Galley Garages that run along the seatback of the Dinette/Settee.  The glue bottle will help give you a sense of size and scale of the interior.
IMG_20191230_114740Same glue bottle inside this other set of Garages which run along the Aft windows to show how these interior volumes vary.

You can see how Selim and Omur have finished off all the solid Rosewood edging around each door frame and have carefully filled and sanded all the outer surfaces flat and smooth.  All this is in preparation for the final step of applying the carefully matched Rosewood veneer to all these exterior surfaces.
IMG_20200103_105739 If you check out the shapes of these Garages in the renderings above and notice the mitred corners where each set meet and make the 90 degree turn, you can appreciate how much of an Origami like puzzle it is to figure out the shape of the single piece of Rosewood veneer needed to wrap around all these exterior surfaces.

Here is on Garage’s veneer all carefully selected and taped together ready to be laminated to the cabinet behind.
IMG_20200103_172335But just how are they going to manage to glue this single sheet to all those surfaces keeping everything lined up and getting the veneer tightly squeezed against the cabinet surfaces?

Clues to the answer lie in the strips of black tubing you may have noticed in a few shots and this one on the left.  And you will also note how the open end of this cabinet has all been stuffed full of foam?
IMG_20200103_125851Hmmmm, more of that black tubing running around all the corners and edges ……….
IMG_20200102_113610More clues here with this vacuum gauge……
IMG_20200102_113601Which is part of this big vacuum pump and what you see in the background answers the riddle.

Yup, they are going to vacuum bag all the Garages and glue the Rosewood veneer on in a similar way in which the new high tech composite fiber such as Kevlar are being laminated in their molds.
IMG_20200103_172200Each cabinet takes it turn being wrapped up in this special vacuum forming plastic and you can now see the purpose of that black tubing……..
IMG_20200102_113441…………. and the foam is to keep the plastic sheeting tightly sealed as it goes around corners and the foam is to keep the plastic from being sucked inside any openings on the ends as they take the vacuum up to about 600mmHg. 
IMG_20200102_113355That’s a LOT of vacuum, and you can see evidence of that in this shot where the veneer spans one of those cut outs for the window mullions we saw earlier and notice how the veneer is being pulled down into the vacant space by the vacuum inside.
IMG_20200102_113333Hakan is helping Omur to monitor the progress and keep everything sealed as they pull down more and more vacuum on this largest of the four Garage cabinets and use the internal vacuum to apply huge amount of evenly distributed pressure on the veneer to adhere it perfectly flat against the inner core of the cabinets.
IMG_20200102_113427This shot looking down the full length of this cabinet the reflection helps show how well the vacuum pulls the veneer tight and flat against the underlying cabinet.
IMG_20200102_162832The fully vacuum bagged cabinets are left for at least 8 hours for the glue to fully set and then the vacuum is released and the plastic pulled off.

Now they can remove all the black plastic tubing and foam.
IMG_20200102_162911The overlapping veneer can now be easily trimmed off with a sharp knife and others are cleaned up with a hand router.
IMG_20200103_105606Like the caterpillar that finally emerges from his cocoon and becomes the most beautiful butterfly our Garages emerge from their plastic cocoon to reveal THIS beauty! 
IMG_20200103_105620I had to touch it to make sure it was real.
IMG_20200103_105642I could stare at this all day and this is the ROUGH out of the bag finish!
IMG_20200103_105824And just wait till you see what these Garages look like once they are all joined together in the Galley sporting their swirling Rosewood grain all matched up.  Omur showing us some of how that magic happens as he checks out the next pieced together sheet of matching Rosewood for the Garage which runs perpendicular to the long one on the ground to the left that we just watched emerge from its cocoon.
IMG_20200103_105845Selim helps to carefully position the veneer in just the right spot which is marked off on the tape to register with a matching mark on its Garage cabinet as it gets ready to be vacuum bagged.
IMG_20200103_125804A closeup of the long cabinet showing how the veneer and the solid edging match up.
IMG_20200103_125815Next step is to radius all these corners with a 5mm router bit for that “quilted” look I so like and has been done throughout all the cabinetry on Möbius.

But WAIT!  There’s MORE!!!!

IMG_20200103_105149Upstairs in the Finishing Shop, that team has started to apply the 5 coats of clear PU varnish to some of the cabinetry that has recently been finished so let’s finish off this week’s Progress Update with a peek in there.
IMG_20200103_105210These are some of the cabinets from my Clean Workbench/Office in the Corridor we saw earlier.  Check out how well the Rosewood contrasts with the inner Beech surfaces.
IMG_20200103_105225Only 2 of the 5 coats of PU and already looking awesome to my eye.
IMG_20200103_105241Here is the cabinet you may remember seeing a few weeks ago inside the Guest Cabin Head with the little White sink on top.
IMG_20200103_105249Some might say why bother to finish off areas like this bottom of my Office cabinet with the groove for the indirect LED floor lightning strips when only a mouse would be able to see it?


Because I know it’s there and it makes me VERY happy knowing it.
IMG_20200103_105158But I don’t think anyone will question why we are going to such lengths and expense to use Rosewood for all our interior when you see results like this starting to emerge.
IMG_20200103_105205_MPMother Nature is as close as I come to religion which is a big part of why I am so filled with profound joy when I’m out at sea.

IMHO, she outdoes even her awemazing self with examples like this.  Do your eyes and your soul a favor and click on this image, ideally on a very large and very good screen and join me as I just sit in awe as I stare at this perfectly flat surface that convincingly fools my eye into thinking it is a beautiful brown curtain being pulled back to reveal that creamy depth inside.

NOW you might understand why I refer to Möbius as a combined work of art and engineering.
I can’t top Mother Nature so I will leave you here as I go back to stare at her latest magic.

Thanks for joining us again this first week of 2020 and year of the launch of XPM78-01 Möbius.


Beauteous of Works of Art & Engineering: XPM78-01 Möbius: Progress Update Dec 16-21, 2019

Beauteous of Works of Art & Engineering: XPM78-01 Möbius: Progress Update Dec 16-21, 2019

Say it isn’t so?!!  We’re heading into the last week of the year?  How the heck did THAT happen so fast??

In my naïve youth I used to think that time would slow down as you got older and especially when you “retired” but I’ve never been busier in my life and time has never whizzed by faster.  I think that the reality is that time is one of the few constants in life and doesn’t care how old we are, how busy we are, how much we need to get done, it just ticks away like some rock solid metronome one second at a time.  Back in 2009 I recall a similar year end experience in what was then my second year of single handed sailing around the world in my former sailboat sv Learnativity, where I was recalling all the different experiences I had been through in the past two years and not being able to believe it was possible that ALL that could have happened in just two years.  Drove me crazy for a week as I was sure that somehow my “math” was wrong because it MUST have been more like fife years.  But nope, it was just two.  Over time, hehehe, I came up with the notion of Learning/Living Density or simply Experiential Density and that is perhaps the variable; same amount of seconds in the year, just varying amount of experiences, learning and living for each of us.  Whatever the case 2019 has been a year VERY densely packed full of awemazing experiences and learning for Christine and I and I would hope that is the case for all of you as well.  But enough philosophising and let’s get busy reviewing the density of experiences building Möbius this past week of December 16-21, 2019


IMG_20191120_121849As per part of the title there was some eXciting progress with on the Steering related equipment on XPM78-01 this week as well as many other systems and I’ll take you through all of those as well, however steering is perhaps THE most important system on any boat and especially on a power boat and eXceptionally so on an XPM given the eXtremely remote locations we and other eXtreme Passage Maker type boats tend to roam. 
IMG_20191120_121842On a sailboat if you were to lose all your steering such as having your rudder fall off then it is relatively easy to steer the boat using the sails.  Ask me how I know! 
IMG_20191120_121901However with no sails if we were to ever somehow loose ALL steering capability on Möbius about the only option we would have would be to use one or our drogues or other warps you can fashion from long knotted or weighted lines and drag them off the Swim Platform and change the direction of the boat by moving the attachment point from side to side. 
IMG_20191118_105539All that being a VERY Waynewinded way of saying that we take the Steering System on the XPM’s VERY seriously.  Uğur will help give you a better sense of size and scale of the rudder so you can see that it is both eXtremely strong and eXtremely big.

The other photos above show the rudder in various stages of construction and it is now all complete and ready to be installed so let’s go check out this week’s progress.
IMG_20190919_145617These are the pair of self aligning PETP roller bearings which I worked closely with Thor Christen Hermann. the Systems Designer at Jefa Rudder Bearings in Greve Denmark to get them just right.  Thor and everyone at Jefa was fabulous to work with and I can recommend them highly for any of your rudder related needs.

Jeffa rudder bearing Xsection diagram w rudder postIn the photo above the bearing on the left is the top bearing, lower on the right and the white ring in the middle is a thrust bearing to deal with any vertical forces and the black ring is anodized aluminium lock ring that is secured to the Rudder Post with locking setscrews.  This section view from Jefa clearly shows how these bearings are mounted inside the yellow coloured rudder tube which is an integral component welded into the hull’s framing.
IMG_20190919_145652A closer look at the lower bearing lets us see the black rollers for the 127mm/5’” aluminium Rudder post to smoothly glide on and down by my thumb you can see how the white inner race with these rollers inside, rotates inside the white spherical outer race which is fasted into the top and bottom of the Rudder Tube as seen above.

IMG_20191216_102927Next up, the 200mm/8” thick walled aluminium Rudder Tube is tacked in place after being precisely positioned with laser levels such that it is perfectly aligned in all directions and exactly on the centerline of the hull.

Let’s go see where those beautiful tendrils of smoke are coming from?

IMG_20191216_102634Aha!  Now that Uğur and Nihat have tacked the Rudder Tube into position and also tacked on the additional 25mm/1” thick support braces, everything can be fully welded into the hull.
IMG_20191216_154822This is one of the last major welding jobs to be completed and only leaves the installation of the Nogva CPP propeller and shaft to literally float our boat in the sense that she will be fully watertight.

Naval is using the latest Pulse MIG welders and in photos like this one you can actually see the pulses refracting the light which I thought was cool.
IMG_20191216_102705Good comparative shot of the tack welds and the fully finished welds around the circumference of the Rudder Post where it exits out the top of the curved 15mm/ 5/8” plate of the Prop Tunnel.
IMG_20191216_122508That same area now fully welded on the inside ….
IMG_20191216_154700… bottom of the Rudder Tube fully welded on the outside…..
IMG_20191216_154958 … and top of the Rudder Tube fully welded to the Rudder Shelf inside the very aft end of the Workshop area.  Door on the left puts you out on the Swim Platform.

Once everything cooled down the Jefa Rudder Bearings could be test fit into the Rudder Tube and we are looking up from under the boat to see the bottom Rudder Bearing here. 

Next step will be to pump a special adhesive through a hole drilled through the side of the Rudder Tube and out a hole in the other side to fill up the special groves in the outer white bearing race and solidly affix the outer bearing to the Rudder Tube.
OK, we’ve got a Rudder, we’ve got a Rudder Tube and Rudder Bearings, but how do we TURN the Rudder?

IMG_20191218_172918Oh right!  The Tiller Arm I designed and has now been fully machined and fresh off the table of the CNC milling machine over at Tasot.  If you’ve been following these weekly progress updates recently you’ll recall seeing this at huge block of aluminium being machined into the finished beauty you see here.
IMG_20191220_115855I walked over to Tasot a few days ago with my rolling cart and brought this work of art and engineering over to Naval to test fit it to the Rudder Post. 

Easy to see how these two halves will be clamped to the top of the Rudder Post with four long M16 bolts running through the four holes in the wings of the body of the Tiller Arm.
IMG_20191220_115926These hardened and precision ground 25mm/1” OD pins are a close sliding fit into the Tiller Arm.
IMG_20191220_115936Providing a super strong axis for the Heim joint ends of the two big Kobelt hydraulic steering cylinders we will see shortly below.  Locking nuts threaded onto the ends of these pins will hold them in place.
IMG_20191220_120741Back at Naval now for the first test fit.  I have implicit trust in 3D models and the precision of CNC machining but we didn’t take the Rudder over to Tasot while the Tiller Arm was being machined so it was a great feeling to set this half onto the Rudder Post and have it fit perfectly!
IMG_20191220_120655And of course the other half fit just right too.

Note the 18mm wide keyway cut into the top of the Rudder Post and in the photo above you can see the matching keyway cut into the Tiller Arm body.

The large through hole at the top of the Rudder Post is also part of the Steering System, the very end of the chain of redundancy and backups.  There is a 70mm/2 3/4” OD thick walled aluminium pipe that is 2m/6.5′ long that can be inserted into this hole in the top of the Rudder Post and be used as an Emergency Steering Tiller. 
At the other end of this Emergency There are attachment points for block and tackle lines to run from the end of this Tiller to the hull frames on each side which would be used to lock the Tiller pipe in any location and move it as needed to steer.  Obviously a bit of kit we hope to never use, though we will test on sea trials, but all part of the “belt and suspenders” approach we take for Steering and throughout the whole boat which enables us to be “Ready for the Unexpected”.


Continuing with this “knee bone connected to the thigh bone” and connecting the dots of the Steering System components, we now need to connect the Tiller Arm to the Kobelt hydraulic cylinders and that is what this next bit of Steering beauty is for.  The bronze part in my hand is technically referred to as a Heim joint which is a spherical ball and socket type of joint which transfers the force from the Steering Cylinder to the Tiller Arm.

IMG_20191220_121037Kobelt equipment is eXtremely robust with their two favorite materials being bronze and stainless steel which you will be seeing a LOT of in the coming weeks as we get all the Kobelt equipment installed.  With this Heim joint you can see how it is built to last for thousands of hours at sea with very little maintenance.  A quick squirt of grease in that Zerk fitting to ensure these spherical SS ball and bronze socket are well lubricated and don’t wear is about all that should be needed throughout the long lifetime of these critical joints.
OK, so now the Heim joint connects to ………???


This next example of the result when art meets engineering are these Kobelt 76mm/3” ID 7018 Hydraulic Steering Cylinders. 
IMG_20191220_121331The mounting base is where the cylinder is through bolted to thick pads on the Rudder Shelf you saw earlier.  This is another SS/Bronze spherical joint the same as the Heim joint at the other end just encapsulated in this cast bronze base and again a simple Zerk fitting to keep this joint well lubricated, friction free and long lasting.
IMG_20191220_121352And the Heim joint threads onto the other end of the SS shaft Steering Cylinder tom complete the Steering System’s connection to the Tiller Arm.
But wait!  What causes those big beefy hydraulic cylinders to move in and out you might ask, and I’m so glad you did.

IMG_20191219_142422Because I get to show you the final entry into this week’s Art & Engineering Beauty pageant, these Kobelt/Accu-Steer HPU400 Hydraulic Power Units.  The anodized blue assembly on the right end is the very powerful hydraulic pump and the white cylinder under my hand is the 24V motor that drives the pump.  There are two of these two speed pumps, one for each cylinder and we designed these with Kobelt engineers such that one pump and one cylinder exceed the steering requirements under the most severe conditions. 
IMG_20191219_142414Most of the time we will run them this way, one pump/one cylinder and alternate between the two every day or two when we are on multi week passages so we know they are both working and to keep them balanced for wear and use.  If conditions were severe we can chose to run both pumps and both cylinders at the same time for even more power.  In situations such as close quarter maneuvering such as docking in tight spaces, we can switch the pumps to their high speed and cut our 45 degree lock to lock time, 90 degrees total, in half.

Stay tuned for upcoming episodes where we are installing these pumps.

IMG_20191220_115034Some of which Cihan (right) and Okan already got started on this week as well.  They are busy making the two AL shelves to mount the two Accu-Steer HPU400 suspended above the Tiller Arm in the aft end of the Workshop.
IMG_20191220_115045The shelves have flat bar edges so that any spills of hydraulic oil over time are contained and easy to spot as well as easy to clean up.  The three L-bar pieces tacked in place are for the six SS and rubber isolation mounts that secure the HPU pumps in place and keep them running silently.  Next week you’ll see these shelves being mounted.

Whew!  And that only gets us through this week’s work on just the Steering System so let’s move on to the next area of progress; plumbing!


IMG_20191218_163822We’ll stay with the multi-talented team of Cihan and Okan as they work on more of their plumbing jobs down in the Basement.  While they were in the fabricating mood and tools they built this support rack for the Potable/Drinking Water tank. 
IMG_20191220_142101This poly tank is another example of the “Readiness for the Unexpected” approach in that it will hold 210L / 55 USG of fresh water that will be kept independent of the rest of the boat’s water tanks and domestic water systems.  It will be plumbed to an independent water pump and connected to a second faucet at the Galley sink.

IMG_20191220_142055The only potable water we allow onboard is what comes out of our 200L/52USG per hour watermaker, never any shore side water so we know the quality of the water is the highest, being essentially pure H2O.  However, there is always the chance, however remote, that the water in the six integral aluminium hull tanks could get contaminated or even more unlikely could escape.  So this tank with its own pump and filtration system will always be at the ready just in case the unexpected should happen.

The white unit on the right is the Vacuum Generator for the Guest Cabin VacuFlush toilet.

IMG_20191218_125119Above the VacuFlush Vacuum Generator is this manifold which controls the hot water flowing to the three zones of the in-floor heating in each Cabin.
IMG_20191217_163239Cihan has done his usual masterful job of installing these manifolds and picking up where we left off last week.  Domestic Hot Water DHW from the IsoTherm Calorifier flows into the red handled shiny SS upper Supply manifold and then out the three fittings with the red flow meters on top. 

Zone 1’s gray PVC/Red handle ball valve is dry fitted in the center to help determine the location of the circulation pump mounts which are the two aluminium L-bar pads on the right.  Zone 2’s pump will mount on the pads you can just see at the bottom right and more fully in the photo below.

IMG_20191217_163231After circulating through the 15mm PEX tubing embedded in the floors in each zone, the slightly cooler water flows into the bottom of the polished SS Return manifold  through the 3 SS threaded fittings below the 3 white flow control valves and returns the water back to the Calorifier via the black insulated PPR pipe with the blue handled SS ball valve.

There is a temperature gauge on both the Supply and Return lines to make it easy to see the temperature differential and performance of the system.  The vertical SS units on the left ends of each manifold are for draining/filling the system and for bleeding off any entrapped air.

IMG_20191216_122827These are the AL brackets which Cihan has come up with for mounting each of the three speed Zone Circulation Pumps to the bulkhead.
IMG_20191218_125142Here is the completed bracket test fitted to one of these pumps.  Longer bolts will be used with an additional nut on each end to keep the clamping of the pump’s sealing flange independent of the mounting nut.  Each one of these pump mounts will be bolted to those pads you saw in the photos above with rubber noise isolation separating the mounting bracket from the pads and keeping noise and vibration locked up in the Basement.


Well, let’s give Cihan and Okan a bit of a rest and move on to the ever busy Aluminium team of Nihat and Uğur.

IMG_20191217_162937After spending the weekend in the freezer to shrink, the orange coloured Cutlass bearing was pressed into the outboard end of the Nogva Prop Log Tube you saw being installed last week.  The groves in the upper half ensure that water flows freely out of the tube and provides a steady supply of clean water to lubricate the prop shaft. 
When rotating the prop shaft “floats” on a thin film of water so that the Cutlass Bearing material and the prop shaft only touch when the prop is not moving.

IMG_20191217_181519That all set the stage for the Nogva CPP Controllable Pitch Propeller to be test fit.  The smaller diameter end of the CPP prop hub at the bottom here is what fits inside the machined AL housing you see in the photo above.  The stepped flange slides in about half way 20mm/3/4” into the AL housing and acts as a rope guard when, never if, you happen to snag a lobster pot, fish net or other underwater debris.
IMG_20191217_181506At the opposite inboard end of the CPP Prop Shaft is the push/pull rod that runs inside the hollow prop shaft all the way from this threaded end to inside the bronze CPP prop hub.  As this rod is moved fore/aft by hydraulic pressure inside the Nogva CPP servo gearbox the bottom end of each of the four prop blades is rotated in synch to change the pitch from zero to full forward or full reverse.
IMG_20191118_102450Okan then gave the whole prop and shaft a thorough cleaning and a small army of men picked up the eXtremely heavy prop/shaft assembly and carefully slid it through the Cutlass Bearing until that stepped bronze end of the prop hub was the correct 20mm inside and attention can now turn to positioning the mounting brackets for the Nogva CPP Servo Gearbox inside the Engine Room and which we will pick up on in next week’s installment.


IMG_20191216_154850Speaking of the Engine Room, Nihat and Uğur were busy in there as well this week.  With that clue can you guess what they were working on based on this photo?
IMG_20191216_155737Full marks to those of you who guessed Sea Chests!  These are located at the very front end of the Engine Room with the larger Supply Sea Chest on the right and Exit on the left.  There will soon be two Vetus strainers flange mounted to the two pipes coming out of the Supply Sea Chest which will then both feed a sea water supply manifold for consumers such as the Water Maker, Gardner heat exchangers for cooling engine oil and coolant as well as the Nogva heat exchanger and then exiting into the wet exhaust system.

IMG_20191216_155848The 25mm/1” thick Engine/CPP beds are the flat sloped surfaces running top to bottom in this photo, water tanks on either side of them with their respective access ports bolted in place and SAE flanges around them for tank gauge senders and fill/supply lines.  Engine Room diaphragm Bilge Pumps can be seen on either side of the WT Bulkhead with the Guest Cabin/Office on the other side.

IMG_20191216_155803Not easy to get the MIG gun all the way down here but the welder did a great job of getting a full set of deeply penetrating welds around the circumference of this Supply Sea Chest.


IMG_20191219_120651Yet another exciting bit of progress was Nihat (left) and Uğur getting started on the frames for all the WT Doors!  They started with this door on the Port/Left side of the Swim Platform that provides access to the HazMat where we can safely store any Hazardous Materials such as diesel, paints, thinners, etc..
IMG_20191219_120701This one door they will build entirely in house here at Naval and the others will be high end WT fully certified WT doors from Bofor. 

Here they are fabricating and tacking in place the inner flanges for the HazMat door frame.
IMG_20191219_143013Which they complete very quickly,
IMG_20191220_141813With the exact sizes of the frame now set, they moved on to fabricating the HazMat door.
IMG_20191220_103140And had that knocked out just as quickly.  Next week they will fabricate and mount the hinges and seals.
IMG_20191220_104935Sliding over to the opposite Stbd/Right side of the Swim Platform they tacked the inner frame flange for the Bofor WT door.  These doors will be bolted in place with industrial adhesive in between to seal completely.

Bofor D0hg_exterior_duzeltilmisBofor is custom building all the WT doors for Möbius to our specifications but will look similar to this one.  To be fully WT certified there will be two dogs/locks at the top/bottom rather than one as you see here and our doors will be left unpainted AL to match the rest of the boat.

The WT off the Aft Deck into the SuperSalon will have a full length window whereas the one on into the Workshop and the one between the Guest Cabin/Workshop will have a single window like the example here.
IMG_20191220_104940With the mounting flange tacked in place, Nihat trims it to final opening size for the Bofor door frame to set into.
IMG_20191220_103945_MPCihan clowning it up to show how the door frame and flange look from inside the Workshop.  The Accu-Steer pumps and Tiller Arm you saw earlier in this post are sitting off to the right of this photo.
IMG_20191220_164221And before you know it the frame flange is fully welded in place and ready to have these corner welds cleaned up and radiused.


IMG_20191217_163100More beauty to be found inside of Möbius this week as always.  Omur, Selim and Omer often get to steal the show as their expertise and craftsmanship really shines as they work with the rich grain patterns of the Rosewood.  This corner where the lower Freezer cabinet meets the taller Fridge cabinet is but the latest of many examples of their attention to detail with things such as matching the grain patterns to perfection.
IMG_20191218_125018Stepping back a bit from that same intersection to show how the grain swirls forward onto the wall cabinet for the 50” monitor on the Port side of the SuperSalon and Main Helm.
IMG_20191218_124959A few more steps back to show how the wall has been recessed for that large monitor.  It will be on a HD swiveling mount which allows us to pull it all the way out of the cabinet, swivel it forward and aft and tilt it up down.  This enables us to use this screen for both entertainment viewing of movies and photos from either the Lounge chairs or the Settee for our “dinner and a movie” nights and then quickly reposition it for ideal viewing from the Helm Chair when underway.
IMG_20191218_124830Yet another example of Ömür’s creativity and craftsmanship are these little cut outs so you can easily slide your fingers round the back of the monitor to pull it out.

IMG_20191217_163804Over in the Cabinetry Workshop with his compact sold edge router in hand, Omer shows one of his latest examples of grain matching mastery on this panel that will soon go into the Guest Cabin.
IMG_20191220_141926Back aboard Möbius and down in the Master Cabin, Omur and Selim start a new job of fabricating the laminated Rosewood liners for the insides of each of the ten hatches we designed and built in house.
IMG_20191220_103429They use this special laminating material which as you can see is extremely flexible and can be easily shaped and formed however you wish.
IMG_20191220_142013Solid wood corner blocks are glued in place to provide the backing for the large radius corners of each hatch.
IMG_20191220_164348Then successive thin layers are glued up, let dry and the next layer applied.

We will pick up on this process next week as the laminations continue and then the solid Rosewood edges and veneer goes on to finish these beauties off.


IMG_20191217_172949The pace of ordering picks up as we get nearer the end of the build so there are more and more new arrivals showing up each week now and here are a few quick examples to leave you with.

Like these four bolts of leather for our interior walls and ceilings!

IMG_20191217_172955One bolt of black leather for the Helm Station surfaces and ceiling above to minimize reflections, one bolt of white leather for the removable ceiling panels and two bolts of this gray/green leather for the upper wall panels.  Can’t wait to see and be able to show you these as they get installed!
IMG_20191221_113340And then five cartons like this one from LiteMax in Taiwan.

Can you guess what’s inside?

Yup, our five sunlight readable monitors! 

Two 19” ones side by side at the Main Helm station, two 24” side by side up in the SkyBridge Helm and one 43” on the Starboard/Right side of the Main Helm Chair.


I think Captain Christine likes them.  As well she should as she spent months researching and tracking these down.  Our requirements are eXtreme as usual as we need monitors which are:

  1. Full Sunlight readability (1000 nits+) most new smartphones are about 200-280 nits
  2. Dimmable all the way to black for night watches using real front mounted buttons and knobs
  3. Multi-Touch enabled (PCAP)  same as your phone
  4. SXGA resolution 3840 x 2160 or better
  5. Waterproof & Ruggedized

Oh, and affordable too please! 

A tall order to say the least and Christine and I would like to give an eXtremely BIG shout out and thanks to Peter Hayden of mvTanglewood fame for all his help in the early stages of this search as a result of all his efforts in searching for monitors for his previous Nordhaven 62 and now the new N68 he is having built.  Peter had tracked down several of the companies who are the OEM Original Equipment Manufacturers for these kind of high end monitors for the marine industry.  If you are not familiar with Peter’s work on mvTanglewood and his constant flow of expertise on the Trawler Forum, do yourself a favor and go check this out ASAP.  Peter is an endless source of great ideas and expertise and writes outstanding explanations of his work and experiences.   A MUST read for Christine and I and we hope to share an anchorage with our two boats in the not too distant future.

This led us eventually to LiteMax in New Taipei City in Taiwan who make the monitors for airports, railways, stadiums, ATMs and the like and who were willing to make us the Goldilocks just right monitors for us.  It took several months of working with them to get these speced and built and then air freighted to us here in Antalya but they arrived his week and we could not be happier as you can see from my Captain’s face!

They only arrived on Friday and we had a busy Saturday with no time to do anything more than unbox one but we hope to get them setup and tested next week and will bring you more details then.  Just one of the literally thousands of decisions we make and problems we solve every week on this grand adventure of designing and building our just right new boat and home.

Thanks for joining us, please put your comments and questions in the “Join the Discussion” box below and we’ll see you here again next week.

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

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

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


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

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

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

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

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

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

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

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

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

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

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

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

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

IMG_20191209_133256This is the 5 axis CNC machine in the middle of machining the body of the clamp block.
IMG_20191209_133302Closer view of the Clamp Body with one side finished and ready to be flipped over to machine the other side.
IMG_20191211_153749Hamdi proudly showing the finished Clamp Body.
IMG_20191211_153809IMG_20191211_153803One half done, now on to the Tiller Arm Body.
IMG_20191213_111224With one side of the main Tiller Arm body finished, roughing out the second side begins.  Easy to see why this is called “subtractive manufacturing”.  3D printing is the opposite “additive manufacturing”.
Here is a short little video I’ve put together to show you what this looks like in action.

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

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


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


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

See something new though?

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

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

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

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

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

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


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

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

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

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

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

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


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

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

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

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

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

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


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

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

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

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

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

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

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

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

OK, now back to our regular programming.

Mr. Gee Gets Naked!

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

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

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

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

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

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

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

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

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


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

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

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

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


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

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

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

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

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

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

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

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

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


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

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

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

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

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

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


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

Why do we care? 

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


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

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

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

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

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

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

More to follow next week so stay tuned!

  But WAIT!  There’s more!

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

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

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

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

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

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

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

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

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

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

But WAIT!  There’s still MORE!

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

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

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

And so that’s the week that was Nov. 25 to 29, 2019 here on Project Goldilocks with Team Möbius.

Thanks SO much for taking the time to join us and PLEASE be encouraged to put your questions and suggestions into the “Join the Discussion” box below.
