This was a week full of wonderful gifts the first of which is that Möbius now has her one and only official Captain!
Christine 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.
Any guess what Yigit knows is all wrapped up in inside this pallet full of boxes? Uğur lent a helping hand and was just as curious. The unusual L shape of the two big boxes might give you some clues…………….. How 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? Heating 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? That’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. We 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. I 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.
Another 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.
OK, 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.
Many 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. It 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. We 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.
Castoldi 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. As 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 designed this 224DD model to be specifically matched with and direct driven by this 110HP Yanmar which factored into our decision as well. As 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. One 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 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.
Let’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. Cihan 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. Here 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. Cihan 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. 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.
This 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. Same 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. Some 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. I 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!
These 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. More 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. If 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. The 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. Okan 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. Last 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.
We 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.
There 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? Help if I show you where those Red & Black cables lead to next? Correct! 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. The 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. Click 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. Having 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. And these ones over on the Starboard/Right side …….. ……….. and these ones coming down from the Arch into the ceiling of the Guest Cabin and running forward into the Basement.
This 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. Peeking 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. Similar 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 ….. ……. our Electrical System. This 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. One 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.
And the flood of Victron Blue boxes begins!
Victron 120/240V Isolation Transformer on the Left for the rare occasions when we have shore power. Two 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. Here 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.
On 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. A 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. A 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. 12 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. Maybe 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?
WORKSHOP & ER PANELING:
The 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. As 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.
RUDDER & TILLER ARM:
The 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. These 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. Which 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.
For 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.
The 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. Down 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. A simple job for our in-house machine shop to turn from this big block of White Delrin. And 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. Now 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 CABINETRY:
As 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.
In 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. Here 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. To 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. In 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. Of 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. Once 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. Features 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. These 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.
MASTER CABIN CABINETRY:
Back 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. This 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. Standing 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. Celal has just finished setting the hanging closet at the bottom of those stairs. Omur 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. Doesn’t take them long to put the puzzle pieces back together but it is a bit tricky sliding this into place on its base. But 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. The module for the stacked Washer & Dryer slides in next. Horizontal divider where the ubiquitous Rosewood handhold and Blue Horizon Line will attach is set into its slots. Working 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. Next set of puzzle pieces that make up the Vanity Sink base cabinet and upper Medicine Cabinet. Both 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. Carcasses all in place now ready for their drawers and doors and …….
……… 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! On to the next set of cabinetry, the big Master Bed platform, flipped on its side here starts to go together. Headboard 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. Looking 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. Leaving 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.
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.
We 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.
You 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.
The 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.
These 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. Celal 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. Not 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
This 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. Hilmi 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. Over 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. However 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. So 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.
Down 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. Now 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. Each pump has its own Hot Water line from the Supply manifold so they were plumbed next. Third Supply line going in here. Some 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. The 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! Very 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. However, 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.
Once 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. With 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. The 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. Here 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.
GALLEY GARAGES & SUPERSALON CABINETRY:
However 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. Here 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. Costly 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. As 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. With 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. Which 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.
As they create works of art like this. And this.
Just wait till you see these swirling waves of grain patterns pop when they come out of the Finishing spray booth! A 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 ………………………
Not 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. Sitting 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. Back 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. Omer 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. You can see how these doors are made to be very solid yet very light with their foam filled cavity cores. This 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. However 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. Seen 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. Bookcase 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. These 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.
Switching 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. One 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. If 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. Which is how they are building these corner transitions between the wall and ceiling panels in the workshop. Stbd/Right side Workshop here. Here 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. Stepping 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. Stepped corner details just inside the Swim Platform door. Webasto BlueCool V-Series chiller has been mounted to the built in AL shelving. All equipment is mounted with appropriate types of vibration reduction soft mounts such as these. Next up on the AlucoBond list is the Engine Room. So 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.

I do apologise for taking longer than I’d like to respond to your comments I assure you that I’m reading every one as it comes in and will respond as quickly as the build allows.
Hope your first week of this first year of the new 2020 decade is off to an equally good start and see you here here next week.
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.
While 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!
Naval 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.
New 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. Not 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. We 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. If 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.
Meet 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?!
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?
I’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! Many 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. The 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.
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. Back 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
Centaur 90-265V 50/60Hz “World” 24V @ 60A charger
2 Orion DC-DC 24-12V @ 7A converters
14 100/30 MPPT Controllers
With 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. One 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.
Just 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.
Evidence 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.
This 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.
Here 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!
Uğur, 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.
Rotating 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. First two of the AlucoBond panels to be fitted along the Starboard/Right side of the ER and overtop the Day Tank. Sticks being used to hold the individual panels in place while they are being fitted. Sporting his fashionable New Year’s haircut, Uğur puts in the next panel Aft of the two above. Same story on the opposite Port/Left side looking Aft from the WT door from the Guest Cabin into the Workshop. The walls are next in the queue to have their Alucobond panels fitted. Pardon 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. Looks 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.
GUEST CABIN/OFFICE CABINETRY:
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. Omer 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. There 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
On 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. Stepping 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! Back in the Cabinetry shop these are some of those door frames and door jambs ready to be glued up and finished. Laminated cores wrapped in Rosewood veneer and solid edges makes these both super strong and beautiful. Not that I’m biased or anything. Omer 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. Here Omer is working on the single bed sized frame that folds down to make the Pullman Berth. Flipped over to show how the mattress will be fit inside this frame and stay secure as it is folded up and down. Before 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??? Aha! Yunus, our Stainless Steel guru has whipped up these SS hinges for the Pullman. One 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. With 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.
GALLEY COUNTERTOP GARAGES:
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.
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.
Omur 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. Same 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. Selim 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. Same 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. 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. But 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? Hmmmm, more of that black tubing running around all the corners and edges ………. More clues here with this vacuum gauge…… Which 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. Each cabinet takes it turn being wrapped up in this special vacuum forming plastic and you can now see the purpose of that black tubing…….. …………. 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. That’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. Hakan 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. This 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. The 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. The overlapping veneer can now be easily trimmed off with a sharp knife and others are cleaned up with a hand router. Like 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! I had to touch it to make sure it was real. I could stare at this all day and this is the ROUGH out of the bag finish! And 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. Selim 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. A closeup of the long cabinet showing how the veneer and the solid edging match up. Next 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!!!!
Upstairs 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. These 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. Only 2 of the 5 coats of PU and already looking awesome to my eye. Here is the cabinet you may remember seeing a few weeks ago inside the Guest Cabin Head with the little White sink on top. Some 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. But 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. Mother 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.
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
As 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. On 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! However 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. All 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. These 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.
In 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. A 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.
Next 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?
Aha! 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. This 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. Good 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. That same area now fully welded on the inside …. … bottom of the Rudder Tube fully welded on the outside….. … 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?
Oh 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. I 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. These hardened and precision ground 25mm/1” OD pins are a close sliding fit into the Tiller Arm. Providing 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. Back 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! And 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.
Kobelt 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. The 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. And 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.
Because 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. Most 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.
Some 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. The 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!
We’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. This 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.
The 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.
Above 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. Cihan 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.
After 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.
These are the AL brackets which Cihan has come up with for mounting each of the three speed Zone Circulation Pumps to the bulkhead. Here 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.
NOGVA CPP PROP & SHAFT
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.
After 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.
That 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. At 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. Okan 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.
Speaking 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? Full 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.
The 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.
Not 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.
Yet 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.. This 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. Which they complete very quickly, With the exact sizes of the frame now set, they moved on to fabricating the HazMat door. And had that knocked out just as quickly. Next week they will fabricate and mount the hinges and seals. Sliding 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 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. With the mounting flange tacked in place, Nihat trims it to final opening size for the Bofor door frame to set into. Cihan 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. And before you know it the frame flange is fully welded in place and ready to have these corner welds cleaned up and radiused.
More 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. Stepping 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. A 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. Yet 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.
Over 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. Back 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. They use this special laminating material which as you can see is extremely flexible and can be easily shaped and formed however you wish. Solid wood corner blocks are glued in place to provide the backing for the large radius corners of each hatch. Then 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.
NEW ARRIVALS THIS WEEK:
The 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!
One 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! And 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:
Full Sunlight readability (1000 nits+) most new smartphones are about 200-280 nits
Dimmable all the way to black for night watches using real front mounted buttons and knobs
Multi-Touch enabled (PCAP) same as your phone
SXGA resolution 3840 x 2160 or better
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.
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.
Most 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!
If 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.
A 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.
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.
Back 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. They 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.
Here 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
This is the 5 axis CNC machine in the middle of machining the body of the clamp block. Closer view of the Clamp Body with one side finished and ready to be flipped over to machine the other side. Hamdi proudly showing the finished Clamp Body. One half done, now on to the Tiller Arm Body. With 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.
Meanwhile 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. Choosing 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.
In 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. Looking 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. Limber Holes or ”Mouse Holes” in the corners where these tube braces will be welded to the hull plates ensures that any water which finds its way in here can easily flow to the lowest point and be removed by the bilge pump and not trapped in these compartments.
PROP SHAFT & LOG MOUNTING
You 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? And what might this bit of kit be that is on the floor just below the prop shaft tubes? And what are they mixing up here? Some 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. After 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.
Then 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. Up 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. A 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. With 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! A 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. At the propeller end of the prop tube, water exits out these holes drilled around the circumference of the machined end of the Nogva prop tube.
Next week the Cutlass Bearing which supports this aft end of the prop shaft will be press fit into place and the CPP prop and shaft assembly can be carefully slid in place for checking of the final fit as we prep for installing the Nogva CPP Servo gearbox. ELECTRICK GRILL One 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. Deciding 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.
Speaking 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.
Cihan 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. He 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. Moving 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.
Wonder 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. After 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.
Each 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. In 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.
My 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. Standing 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”. Christine 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. Up 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. All 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. Opposite 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. By 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.
Over 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…. One of the drawer sides which has a matching grove for the biscuit is slid in place. Same thing for the opposite side. Two biscuits and some glue for the final drawer side. Thanks 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. Rinse 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.
Remember 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. Literally 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. Two 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.

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!!
Amongst 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.
With 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. This 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
After 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. Armed with some super HD degreaser, lots of wire brushes and our newly acquired Bosch pressure washer, it was bath time! I 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. And here is the result, a VERY clean Mr. Gee! This 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.
Wow! Surely my calendar is fooling me; December already? Another year winding down to a close? Where does the time go??!? I’ve long been fascinated by the dichotomy of how our sense of time past works where the same amount of time can seem to simultaneously much longer and much shorter. In the case of Möbius it seems like both yesterday and a lifetime ago when we first started this crazy idea of switching from sail to power for our future voyaging. Then we dove head first into the deep end of the crazy pool by deciding to design and build it from scratch and started this wild adventure we are now on.
Here are just a few examples of the kind of mental dichotomy that fascinates me; Last month we passed our two year anniversary of being here in Antalya, 612 days ago (April 6, 2018) the first shipment of aluminium CNC cut plate arrived and construction of the hull began and in a few days (Dec. 19, 2018) it will have been one year since we signed on with with Naval Yachts to build the fully finished boat with them and have it be the first “prototype” of their new line of eXtreme eXploration Passage Maker XPM boats. How is it possible that SO much has happened in SO little time?
Well, not to waste any more time, I will ponder and wonder that question for a long time to come but for now let’s get on with catching up on all the progress Team Möbius has made this past week of December 2-6, 2019.
Let’s start this week’s update with the electrical wiring. The cables referenced in this week’s title include these four black and red eXtreme beauties which carry the eXtremely high amp 24 volt current from the 1350A @24V house battery bank to the fore and aft DC distribution panels. As per their labeling, each of these cables is 120 mm2 which would equate to about half way between the American Wire Gauge or AWG of about 4.5/0000. By any measure these are huge and we are doubling these, two positive and two negative so that each pair carries half the amps. Why such eXtreme sizes? In short, Electrical efficiency such that we keep the voltage loss occurring on these long cable runs as low as possible, meaning that as much of the current that leaves the batteries arrives at the consumers on the other end. Our standard maximum voltage drop for all DC circuits is < 3% and for the main supply cables such as these, we keep it under 2% and hence the large cable size. Last week Hilmi ran the four cables from the Basement up to the Forepeak using the cable trays you see in the photos above and this week he ran the other set of cables up from the basement and along the cable trays under the side deck space flanking the SuperSalon you are seeing here and running back to the Aft DC Distribution Panel in the Workshop. Down in the Basement where the House Battery Banks are located we find this growing collection of different cables which now includes the four 120 mm2 Red/Black cables. We had ordered the negative cable in Yellow which is the preferred new ABYC standard to help differentiate the DC negative from Black AC wires but this large size cable is difficult to find and the Yellow jacketed version wasn’t available for several months so we went with Black and will add extra labels along each cable run to maintain clarity. Not that anyone would likely confuse these huge cables for anything but high amp DC, but you can never be too careful when it comes to all things electric.
The two House Battery Bank bays which as you can see here are integral parts of the framing of the hull straddling the 25mm / 1” thick Keel Bar which is what the floors of these two bays are setting upon. Nihat has been welding in the side framing which will hold the composite containment boxes in place and bolting these floors to the hull. Even though all our batteries are fully sealed AGM type batteries with no actual fluid in them, we are building composite containment boxes to add an eXtra layer of safety to cover any possibility of a leak in one of the batteries. The L-bar frames hold the base of the batteries in place and then there will be a separate frame that wraps around the tops of the batteries and clamps them down to the hull so they can not move even in the unlikely event of a full 360 degree roll.
Uğur and Nihat continued their work on fabricating the framing for the glass and acrylic windows up in the SkyBridge. They have all the L-bar tacked in place that will provide the frames for gluing in the lower glass “eyebrow” windows and then started to weld in the flat bar on top to create the window ledges for the upper removable acrylic sheet windows.
Note the large vent seen in the foreground here. This will have a large mist elimination grill in front of it before all the fresh breezes flow down into overhead diffusers in the SuperSalon.
The front three 380W solar panels attach to a frame which sets just inside the upper angled edge of the space in front of this vent opening and hinges along the upper edge of the vent frame. This hinged frame of solar panels allows us to lower its front edge down onto the aluminium roof panel and seal off this space when we are on passages and then unclip it and raise it to its horizontal position which creates a huge wind tunnel to capture all the breezes coming from the bow when we are at anchor and funnel them all to this big vent and down into the SuperSalon. The flat bar window sills were slot welded to the tops of the L-Bar glass window frames and then ground flush and invisible. The angled support you see on the far right here is the articulated support post that is put in place when the roof needs to be folded down into either Cyclone or Canal mode. Most of the time it is removed and stored in Workshop. The front four support posts for the roof are attached with these bolt on flanges so they can be removed prior to folding down the roof. Same bolt on flanges are mounted vertically where these four posts attach to the the roof frame.
Both of the Cabinetry teams continued to make great progress on their respective cabinetry work for the Galley and the Guest Cabin areas so let’s go check in with them.
The spacious SuperSalon is difficult to capture well with photos but perhaps these two panorama shots will help. This one shot standing in very front where the Helm Chair will be looking Aft.
Click to enlarge any photo. Shot standing on the stairs up to the Aft Deck looking forward. Obviously very distorted views but when combined with the regular photos I hope it helps you visualise this truly Super space. Switching back to normal photo mode AND sparing no expense we have brought Chef Christine aboard to inspect her rapidly evolving Galley. Testing out a simulated pot stirring position where the induction cook top will soon be installed, the Chef seems to approve. Omur and Selim spent much of the week painstakingly fitting the Gull Wing door Garages into the Galley cabinets. With mitred corners and being recessed into the countertops requires very exacting dimensions along all three X,Y and Z axis in order for it all to work and for these Garages to be able to slide into their final position. And when they do, it looks abfab!
For those wondering, the Garages are “floating” above the countertops to allow for the 20mm/ 3/4” thick granite countertops. eXacting is what Naval’s Cabinetmakers eXcel at and here is another example as Omur (left) and Selim try out different sheets from the flitches of Rosewood we’ve purchased. When the thin sheets are sliced off the solid slab of Rosewood they are laid together in in the sequence as they come off so each sheet is different but matched with the one before and after. Omur has brought a series of these sheets onboard and is now trying out each one to find the Goldilocks match with the sheet on the right which forms the back of the dining settee. Selim and Omur also fitted the armrest end of the dining Settee. The top will be padded and upholstered and there will be a door in the Rosewood outer side to provide access to one of the electrical panels that will be housed inside.
LOTS of storage space below and behind the seats as you can see. Opposite the Settee on the far right here, Selim has removed the top of the cabinet for the two side by side freezer drawers and taken it back to the Cabinetry Workshop. Once he has these solid edges attached and trimmed flush, he will take it over to the big veneer press and apply the veneer sheets he and Omur have so carefully chosen. Over on the other side of the Cabinetry Workshop, Omer, perfectly framed by this cut out in the wall panel that goes on the outboard side of the stairs leading down into the Master Cabin, has been making great progress on the complex little cabinet for the sink in the Guest Head/Bathroom.
We’ve made quite a few changes to this early rendering of the Guest Head and my apologies for not having an updated render to show you but if you do a mirror flip of this render in your head (sorry) you’ll be close to the new layout. Omer is demonstrating how the countertop with the sink setting atop the right end will appear to float above the cabinet below and if your mental gymnastics worked well, the image in your head should augment the reality you’re seeing here. Earlier in the week it looked like this with the sink area on the left and the L-shaped that runs down the side of the Head and then wraps around to create a handy shelf behind the VacuFlush toilet similar to what you can see in the original render above. A good example of how the solid Rosewood is glued up to create the large radius corners and the sink surround edges. Which soon looks like this as Omer turns his attention to the veneer he has chosen for the wrap around countertops. He has also fabricated these two large radius corner posts for the cabinet below the sink. Which he is gluing up here. Closeup of those large radius corner posts now glued with reinforcing biscuits into the completed under sink cabinet. Here is how the countertop and sink cabinet will fit together.
Mr. Geeeeee gets a Beautiful New Mechanic!
Mr. Gee as we affectionately call our mighty Gardner 6LXB engine has also been getting some much needed time and attention the past few weeks so let’s catch you up on that. Since she returned from her short sojourn in Spain two weeks ago, Captain Christine has added new title to her already long list by becoming Mr. Gee’s new mechanic! With Commodore Barney thankfully supervising very closely. Currently Mr. Gee more closely resembles Humpty Dumpty as he is all in pieces again after being put together briefly for a complete sandblasting of all his external parts. Now we are busy cleaning up all the internal parts which have accumulated over the 50 years of his previous life in powering a tugboat on the Thames River in England. Christine has these valve lifter assemblies all cleaned up and ready for their new life as the heartbeat in Möbius. Looking back a few weeks, this is what Mr. Gee looked like after giving him a very thorough sandblasting and several coats of high temperature silicone based primer.
Ruby the Wonderdog on the left and Barney the Yorkshire Terror always on duty supervising every step of the way. Loosing his head, two cast iron ones in fact, each of which must weigh at least 70kg/150lbs, next up for removal is the cast iron cylinder block sitting on top here. I had previously removed the old cylinder liners and had new ones pressed in and machined to finished size so they are all ready for their equally new pistons and rings.
One of the great things about these Gardner engines and what makes them surprisingly viable for reuse is that while complete engines are no longer being manufactured almost every part is still being made and available from Gardner Marine Diesel which carries on the Gardner name and heartbeat. So with the exception of the primary castings such as the cylinder block, crankcase, and crankshaft I was able to buy every other part new from pistons and rings, to every bearing, every gasket, fuel injectors, etc. Once Christine and I have him fully scrubbed clean we begin to put Humpty Dumpty back together again and bring Mr. Gee back to his original glory or better.
I have Mr. Gee fully disassembled for about the fourth and hopefully final time since I first picked him up in England two years ago. Here he is stripped down to just his all cast aluminium crankcase. Next week I’ll take him outside for a thorough de-greasing and pressure washing to flush out every nook and cranny to get rid of all the accumulated oil sludge and the sandblasting sand that has crept inside.
Yesterday I tackled the truly massive crankshaft by scrubbing every surface and all the internal oil galleries with degreasing liquid and LOTS of paper towels. Old on the right, partially cleaned on the left. About 3/4 clean now before getting a good pressure wash and some new fibre discs in the torsional damper on the left end.
Visible below the crankshaft is the Cast Iron cylinder block with its new liners and ready for its equally thorough cleaning and prep for reassembly. Old meets new!
The shiny new aluminium ring I’m holding in front of Mr. Gee’s massive marine flywheel is the outer Centamax ring that transfers Mr. Gee’s rotational torque of the spinning flywheel to the Nogva CPP input shaft. Easy to see how simple this Centamax flex coupling is with the outer aluminium ring’s fingers fitting tightly into the matching grooves in the thick rubber disc bolted to the Nogva’s input shaft. The grey cast aluminum housing on the left is off Mr. Gee and mates perfectly to the the matching SAE bolt pattern on the red Nogva servo box. Fortunately for me, the Society of Automotive Engineers or SAE began creating standards for things such as threads and bolt hole patterns back in 1905 and are still being used to this day quite universally and ubiquitously in the manufacturing world globally. Gardner and Sons Ltd. was founded in 1868 and began building engines in 1895 and so they were amongst the very first to adopt SAE standards for their engines. Sound boring? Well not to me! Our union of old and new provides a great example of why such standards matter an enable me to simply bolt our almost 50 year old Gardner 6LXB engine to our brand new Nogva CPP using in this case the SAE14 bolt hole pattern to fasten the new Nogva/Centamax ring to the Gardner’s flywheel. Michael Harrison now runs Gardner Marine Diesel after his Dad retired after working for Gardner and Sons Ltd for most of his working life and then started Gardner Marine Diesel when he bought the entire inventory and much of the machinery when Gardner and Sons closed shop in the early 1990’s. Michael not only found Mr. Gee for us when he was being removed from that tugboat so they could upgrade the tug to the more powerful 8LXB for the tugs newly upgraded job requirements, but he also found this original solid steel marine flywheel “blank”. Next week this flywheel will be machined with the SAE14 bolt pattern on this outer face so I can bolt the Nogva/Centamax ring to it prior to mating the Gardner with the Nogva and lifting them into their new home in Möbius’ Engine Room for the first time. Just a wee bit eXcited about that and so stay tuned for more in the coming Weekly Progress Updates.
But WAIT! There’s more!
NEW ARRIVALS @ Naval Yachts
Remember that crate Christine & I built when we were back in Florida last month? and then filled with the many, many, many parts which we had been ordering and sending to our Florida addresses? And then trucked down to Miami to have it air freighted over to Naval Yachts?
Well, it showed up here on Friday! We’ll have great fun unpacking it and showing you all the contents next week.
But WAIT there’s even mooooooooooore!!!
Look what else showed up on Friday!!
Can you guess what’s inside THIS crate and why our brilliant interior designer Yesim is almost as excited as we are about it? This should help you guess? Do Hakan and Yesim help you get your guesses warmer? Or a peek inside perhaps? Good Guess!! It is our eXquisite Galley countertops which have all be cut from this slab of Turquoise granite at Stoneline. It arrived at the end of the day on Friday so we only had time for a quick inspection and we’ll show you much more as it gets installed in the coming weeks. But we were able to see the bullnose rounded edges and some of the other details and can’t wait to inspect it fully tomorrow. and I promise it is the LAST time for this week but ……………………………………
WAIT! There is just ONE more HUGEY thing to show you………………………………
Christine and I regard ourselves as two of the most fortunate people on the planet because we are surrounded by the most awemazing friends who, in addition to being very good friends, also have talents you just wouldn’t believe. One of dearest friends and most talented artists we know is pictured below, the one and only Sherry Cooper.
Sherry and I first met back in 1981 when she and her husband Rick arrived in Baden Baden Germany where I was living at the time. I was a High School teacher for the Canadian Air Force jet fighter base there and Rick joined us from his English teaching gig in Vancouver BC. In addition to teaching there for the next three years we all traveled extensively throughout Europe, Africa and beyond and our friendship continued to grow ever since.
And I am I telling you this because??
Because Sherry agreed to put her incredible artistic talents to work and design the patterns for those two plate glass walls that form the corner of our Master Cabin shower that you may recall seeing in some of the early renderings of the Master Cabin.
Plain clear glass just wouldn’t fit with the eXtreme beauty aboard Möbius now would it? Plus, unlike me, Christine has a modicum of privacy and wasn’t thrilled by the idea of being on such a well lit stage when she was showering. So we came up with the idea of having the glass etched with some fun and beautiful pattern. But where would we find such a pattern?
Ha! Easy peasy as some of my Canadian friends might say, we mentioned it to Sherry on one of our visits and she delighted us by jumping at the chance to be so involved with the creation of our new home. Several meetings and lots of Emails later we evolved the idea of having a theme that would involve some of the art and imagery of the Aboriginal Peoples of Möbius’ Home Port of Victoria BC. The term “Aboriginal” refers to the first inhabitants of Canada, and includes First Nations, Inuit, and Métis peoples. This term came into popular usage in Canadian contexts after 1982, when Section 35 of the Canadian Constitution defined the term as such.
Then we asked Sherry if it might be possible to incorporate some pictures we so vividly recalled from her prodigious photography work of some otherworldly reflective waters where she and Rick have their boat near Gambier Island? Of course she said!
My apologies to you Sherry for this amateurish picture of your pictures, but really people, can you believe that these are untouched photos Sherry took when she spotted these patterns being reflected in the water as Rick was docking their boat??!!!
So what did Sherry come up with?
Check out what we awoke to find in our Email inbox this morning!
We will now be having one of these images etched into each of the two plate glass shower walls and can’t wait to show you the results when they are done and installed in the Master Cabin.
You are AWEMAZING Sherry! Thanks and just let us know when you are flying over to come see your work on display inside Möbius!
OK, as promised that is finally it for this week’s update. See what I mean about that conundrum of time? How could so much happen in so little time? But it did and I have the photos above to prove it!
