Last Sunday, the 15th, upon our return from London for Christine’s B’day weekend we very willingly joined many of you I suspect as members of the Self Isolation Club or SIC as I’ve been calling it. As my cousin Donna who is also a member of SIC in their home over in Doha pointed out, this is not a very exclusive club anymore unfortunately. Christine and I are very grateful to be together through all this and to be in our wonderful apartment here in Antalya which so far seems to be one of the better spots to be in the world. Antalya has an extremely large and modern medical infrastructure in part because this is a “medical tourism” destination and in part because Turkey has a very good medical infrastructure staffed by world class health professionals.
While not being able to be at Naval Yachts and working on Möbius is a challenge, it is a very minor one compared to our challenges with being so far from our family, children and grandchildren who do not appear to be in as good a location in Florida, California and British Columbia. Christine and I are both feeling very good, are fit and in good health and most appreciative of our situation. We sincerely hope that all of you reading this are finding your ways to be safe, happy and healthy as we all weather this latest storm in our lives and remind ourselves, as we do when in severe storms on passages that “This too shall pass”.
Here in Turkey closures of schools, restaurants and the like happened early this week and those who can are being encouraged to work from home. However the rest of the work force continued to go to work this past week and we will have to wait and see what next week brings. With thanks again to Yigit, Uğur and Hakan for sending me all their photos each day this week, I am also fortunate to be able to bring you this week’s Progress Update and as usual Team Möbius has been very productive so let’s go for a virtual tour of their hard work.
Mr. Gee Gardner 6LXB
Mr. Gee, which is what we call our Gardner 6LXB diesel engine, usually appears near the end of previous Weekly Progress Updates so let’s check in on him first this week. Actually these photos are from the week previous when I had time to give all the large cast aluminium parts their first finish coats of high them aluminium paint.
The ribbed oil pan is in the bottom right, crankcase in the center and the two flywheel housings hanging in the background. I had been thinking of just leaving the aluminium parts bare after sandblasting them thoroughly but I like a very clean engine and the cast aluminium can be a bit porous so I decided to cover all the aluminium with more aluminum in the form of powdered aluminium based paint. This is a silicone based paint that is specially formulated to withstand temps up to 300 C/ 572 F. I’m very pleased with the results and next week when I can hopefully go back to Naval I will give these all one more coat of aluminium paint and then finish it off with a clear coat to seal it all fully. This is the Port/Left side of the crankcase casting that is the “service side” of the Gardner as the factory photo below shows …………… ………. how this is the side that has most of the engines parts that you access when servicing such as the fuel injection pump which is mounted with those two circular clamps you see above, fuel and oil filters, alternator, etc.
Click to enlarge if you’d like to read the basic technical specs on the Gardner 6LXB. These two castings enclose the huge heavy flywheel and that flat surface on the Left one facing this photos is where it bolts to the aft end of the crankcase. The housing on the Right has a SAE bolt pattern flange which matches the one on the Nogva CPP Controllable Pitch Propeller gearbox.
More on Mr. Gee as soon as my SIC membership expires and I can get back to work. Even though he is one of the most efficient diesel engines ever to be mass produced, Mr. Gee needs a good steady supply of clean diesel fuel so we are building an extensive set of fuel filtering systems that include a pair of 2 stage Fleetguard filters, water separators, a fuel transfer and polishing system and a full Alfa Laval centrifuge that can convert even the dirtiest fuel into crystal clear diesel. This requires a series of manifolds and ball valves such as this pair in the Basement for transferring fuel from any one tank to any other. Now we need about four more manifolds for the fuel transfer system, fuel polishing and Day Tank. So the Machine Shop has been busy making these out of blocks of solid 75mm/3” square aluminium which they drill out and tap with NPT pipe threads for the SS ball valves. You’ll see more of these as Cihan starts installing them in the Workshop.
.In the meantime though, Cihan is busy plumbing in all the fuel and water lines in the Workshop and Engine Room. This is looking forward at the Day Tank on the Stbd/Right side of the Workshop with the ER wall on the Left. You can see the water and fuel lines in the vertical trays on the Right and running across the ceiling and down to the ball valves atop the Day Tank. The area between the Day Tank and the Stbd hull is starting to be well populated as the various “highways” of support trays for fuel, water and electrical cables intersect. The horizontal trays here are carrying electrical cables through the penetrations in the WT Bulkhead you can see at the far end.
Vertical hoses are fuel and water hoses. When all the hoses or cables are in, these penetrations are sealed to be fully watertight with a White special certified caulking compound you can see in this penetration under the workbench you see in the photo above. Down below the Day Tank we can see more of Cihan’s handiwork with these water hoses which make the turn into the penetration through the ER Enclosure wall on the Left. The clear hoses are bringing sea water from the intake Sea Chest in the ER back to the Watermaker low pressure Feed Pump and the Circulation Pump for the Webasto BlueCool Chiller. Those water hoses run aft into these ball valves which direct sea water supply and return lines from the Watermaker Low Pressure Feed Pump and the AirCon Chiller Circulation Pump. With the ball valves installed Cihan mounts that SW Circulation Pump to the mount he has previously welded in place. As with all pumps and motors, this is mounted with these vulcanized vibration absorbing mounts. Cihan also has both Deck Wash pumps mounted and plumbed. This is the pump for the Sea Water Deck Wash with its clear filter covered with the white latex glove. The Fresh Water Deck Wash pump is on the far Left of this shot.
Yigit has been extremely busy managing all this work as well as designing and modeling all our systems and this past week we worked with the engineers at Halyard to finalise the design of our wet exhaust system and have them build and ship that to us ASAP. We have refined it a bit more but the earlier rendering below is close to the final design that Halyard is now starting to build.
Gardner engine is shown in the blue silhouette with the Red Nogva CPP gearbox in the bottom Right. Exhaust gases exit vertically out of the Gardner and then run across the horizontal pipe to the blue mixing elbow where seawater is injected to cool and quiet as they collect in the large Silencer/separator on the Left.
Water is then separated and exits out the bottom into the Sea Chest while the cooled gases flow through the rubber S-shaped exhaust hose running down and out through the ER wall and over to the exhaust pipe exiting the hull above the WL
I will show more once we start installing the exhaust system.
I don’t have too many pictures of Hilmi’s progress this week but we have been frequently connected via WhatsApp and he’s been continuing to install more and more of the Maretron BB’s Black Boxes and N2K cables.
For example, he and Cihan installed this new AL panel to mount the multiple Maretron BB’s in the Basement and is now busy wiring them up with their N2K cables and wiring from sensors for Bilge High Water and fuel tank levels. One of the many networks on the boat is the one for all the Victron equipment which is the base of our AC and DC electrical systems. Victron is another one of those tried and true solutions for us so we went all Victron for things like inverters, chargers, isolation transformer, MPPT solar panel controllers, DC-DC converters, etc..
This is our Victron OctoGX, which we may swap out for the just released CerboGX and these both serve as a central communications device to bring all the inputs and outputs together and enable us to closely monitor all aspects of our electrical system.
If you’re interested in more details, click HERE to see the new video from Victron that does a nice job of explaining the many functions of these devices.
On the XPM’s or any long range passage maker boat, this level of monitoring is critical as we literally live off of our electrical system and the consequences of losing any part of it can have eXtremely severe consequences for us. So these comm centers put pool all the data from all the devices and allow us to know right away when anything changes.
In addition to the high dependency on the electrical system components, they also tend to be high initial cost items which we expect to work continuously for at least ten years so just as with human health, keeping our electrical system and all its many components all in top shape and catching any changes and problems early is key to long life spans for these devices.
Hilmi has also been installing other electric components such as these 12V and 24V DC distribution blocks. We have these spread throughout the boat wherever we might want to power 12V and 24V devices. In addition to the 8 port model above, these also come in round 2 port models where fewer such DC connections are needed so we use a mix of both.
We tend to hide this inside cupboards and drawers or below countertops or desk tops to make cable management easier and keep them out of the way. These blocks are very well made and require a single 12 of 24V DC power input which is then distributed to each of the Anderson Powerpole plug in sockets which are individually fused with an standard ATC blade fuse. The block can handle up to 40 Amps which is more than enough for the various chargers, LED lights, fans, radios, and other DC powered devices. Also super handy to have near my workbenches in the Workshop and my Boat’s Office.
Uğur, standing, Nihat, kneeling, and Okan had a very busy week with their typically varied set of jobs such as continuing to install the many doors in the two Vent Boxes on the Aft Deck.
This is the Stbd/Right side Vent Box which looks after all the Extraction air venting and ducting. Door on the far Left and Right access storage areas. Upper Middle frame is for the Extraction air from the Engine Room and Lower Middle frame is for the Extraction Air from the workshop, both with large axial fans built in. Both tops will soon have their AL plates welded on and a bit later these will be covered with some of the Aquamarine Marble countertop surfaces. Taller countertop on the Left will be left as is and the electric BBQ Grille mounts into the lower counter surface on the Right.
The opposite Port Vent Box will be a single level marble countertop with a built in sink. Should make for a great Outdoor Galley. They also whipped up this bracket for the Manual Hydraulic Steering Pump that will be installed inside the Main Helm. This will secure the Kobelt 7012 Helm Pump which is connected via hydraulic hoses to the Kobelt 7080 steering cylinders. We will keep a traditional steering wheel stored nearby that can slide onto the 7012’s keyed shaft and enable us to steer the boat manually. However this wheel will rarely be in place as this is only a last resort backup steering in case either of other two independent 24V steering systems, AutoPilots and cylinders should ever fail completely.
The small gray hole in the center of this rough rendering of the Main Helm Area is where this steering wheel will be inserted if ever needed.
However what stole the show excitement wise this week is this!
The first three of our 14 solar panels are now being fitted. These three 295W panels will be mounted to the frame you’ve seen being built in past weeks. The frame is hinged on its aft end just in front of the center window of the SkyBridge giving it two modes:
1. Locked down in about the position you see here when we are on passage.
2. Tilted up to be horizontal when at anchorage for both maximum solar gain AND to act as a giant wind funnel directing the breezes over the Bow to the big vertical vent Green Mist Eliminator grill you can see in this rough render. The three panels are fastened into the hinged AL frame. Once in place each panel butts up tight against each other to form a single continuous solar surface. Front two panels in place. and then there were three!
In addition to these three 295W hinged panels, there are 8 more 320W fixed panels atop the SkyBridge Roof and then three more 320W panels on the Aft Roof which cantilevers overtop the Outdoor Galley on the Aft Deck.
The combined output of all 14 panels gives us a theoretical total of 4405Wp. We won’t know the actual output until we get out and can do some real world testing but being very conservative if we have the upper 8 panels working at 85% capacity and the three front and back working at 30% capacity a 5 hour solar day would generate about 13.6 kWh and a 7 hour solar day would generate about 19.1kWh Each of our 14 solar panels have their own dedicated Victron 100/20 SmartSolar MPPT controller to maximize their output and give us the most control over losses from any shading of any one panel from nearby structures such as the SkyBridge Roof, Arch, Radar, etc. If multiple solar panels are connected in series to a single MPPT controller then the shading of any one panel reduces the output of all the others as well.
Here’s the “powerful” view from the SkyBridge. Meanwhile down below all our “chippies” on the Cabinetmaking Teams have had another very productive week so let’s go check that out.
Şevki and Selim continue to build out the Master Cabin. All the Green/Gray leather wall panels on the Port/Left side are now snapped in place. All the ceiling panels are removable with FastMount clips holding them in place. The ceiling grid has now been installed and they are installing the White FastMount female sockets you can see in the foreground and then two of the rough cut ceiling panels have been snapped in place behind. View from the entrance into the Master Cabin looking forward to see that the rest of the rough cut ceiling panels have now been fitted and snapped in place. Hmmmmm, what do you think we are witnessing here?
Aha! The Bosch Washing Machine has arrived and is now setting on the Master Bed frame awaiting installation in its cabinet on the front Stbd/Right side. It took quite some time but Buse persevered and was able to source a British version of this Bosch Washing machine Christine had picked out so that the engraved text is in English rather than Turkish. (click to enlarge)
We are now quite used to the Turkish terms that are on the washing machine in our apartment for over 2 years now but still nice to have this all in English for our aging brains and others who might be using this.
Oh, and yes, of course the washer has to have WiFi for my Gorgeous Geekette!
We received this exciting photo on Friday as they put in the Rosewood stair risers for the first time. This is the spiraling stairwell leading up from the Master Cabin to the SuperSalon which we will go look at next. Before we leave the Master Cabin though let’s go look at what Faruk and Osma have been up to in the Master Head & Shower.
They picked up where the left off last week with filling all the joints between the fiberglass panels that form all the surfaces of the floor, ceiling and walls. As you may recall from last week, they tape off each joint with two different layers of tape so they can put on two layers of grout to create a nicely radiused corner.
This past week they put in the 2nd layer with the final radiused corner and once dry they carefully wet sanded and polished the gel coat filled resin compound they use for the grout which creates a polished and seamless interior. With the joints all filled and sanded they could now install the lower sink cabinet and the base for the VacuFlush toilet you see on the Right with the patch of blue painters tape to protect the surface as they cut the hole for the toilet base.
Continuing up the stairs from the Master Cabin, Omur and Selim are now installing the rest of the Main Helm cabinetry with this section overtop of the Master Cabin door. There will be a Black leather covered triangular lid atop the space to the right of Ömür’s hand which will lift up to access the surprisingly large storage space underneath. That allows Selim to start fitting the side panel which makes the corner transition from the panel above the door and caries on below the windowsill on the far Stbd/Right side of the stairway. Stepping back towards the centerline of the boat, let’s turn clockwise for a series of shots to see the layout of all the areas that make up the Super Salon.
Looking directly towards the Port/Left side of the SuperSalon shows the Main Helm on the far Left, Master Cabin stairs to the right of that, then the Dinette Settee and the front half of the Galley Cabinets on the Right. Turning to look at the Aft Port/Left corner of the SuperSalon shows the whole wrap around set of connected Galley cupboards. Which you can see much better if I zoom in on the Galley at bit more. Continuing to turn clockwise you can see the stairs leading up to the Aft Deck in the background on the Right. The taller cabinet on the far Right side where the two 130L Vitrifrigo SS upright fridges will soon be installed and to the Right of that is the shorter more recessed cabinets where the twin Vitrifrigo 70L drawer Freezers will soon be parked. Rotating a bit more reveals the opening for the 50” SmarTV/monitor cabinet. One more twist to the Right lets us see the Main Helm cabinetry. And one final twist to complete the full 360 photo tour we are back to the stairwell down to the Master Cabin with the Settee on the Right. Here’s a different perspective of the SuperSalon looking straight ahead at the Main Helm while standing at the base of the stairs down from the Aft Deck.
The large open hatch in the center provides access into the huge Basement area which is under the entire area of the SuperSalon floor. Off to the far Right of the photo above here is a sneak peek at the first of the Galley Garages which sit atop the marble countertops and I look forward to showing you the rest of these Garages as they are installed next week. And of course, the Blue Horizon Line or BHL you first saw being installed last week, continues to go in all around the circumference of the SuperSalon. More BHL running along the upper edge of the Settee. BHL on the Port side along the upper edges of the Fridge and Freezer cabinets. and starting to make its way around the Main Helm. Whew! Even though our 14 day self isolation prevented me from being there at all this week, I’m exhausted just taking you on this photo tour! A big thanks again to Yigit, Yesim, Uğur, Hilmi and Hakan for keeping me so well connected to the build via WhatsApp text, video and photos all week and for providing me with all these photos so I can share it all with you.
With luck my membership in the Self Isolation Club hopefully expires next Sunday the 29th so I only have one more week until I can join Team Möbius at Naval Yachts. But in any case I will be back with here next weekend to bring you the latest Weekly Progress Update of XPM78-01 Möbius.
We sincerely hope that all of you joining us here are finding your own ways to be safe, healthy and happy and that perhaps we can assist a wee bit with your entertainment during these crazy times.
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.
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.
If this stuff interests you as much as it does me then please stay tuned and be sure to subscribe to the blog so you don’t miss any of the new articles as they go live.
OK, now back to our regular programming.
Mr. Gee Gets Naked!
Captain Christine is now working at the Naval Shipyard with me most days now as we make the final push to finish this build and bet Möbius and ourselves back were we belong; ON THE WATER!!
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.
With apologies for taking so long to do so here finally is the long overdue weekly update for all you patient followers.
As you might recall from the last post, I flew to Florida to meet up with my Beautiful Bride Captain Christine who had been there for almost 6 seeks looking after a myriad of things from ordering boat parts, to updating her 100 Ton Captains license to being Gramma to our Grandson Liam. I was there to help introduce Baris and Dincer, the brother owners of Naval Yachts to the US and the huge Ft. Lauderdale International Boat show known as FLIBS. And then I had hundreds of boat parts to order, have shipped to us in Florida, make and crate it all up to be air freighted over to Naval and somewhere in there fly up to BC to see family and friends there, down to LA to have our CanAm (I’m Canadian, Christine’s American) with our similarly CanAm family and Granddaughters.
I had naively hoped to be able to find the time to keep up with these weekly updates while I was away for the past three weeks on a truly whirlwind tour of the US and Canada, but I came up against one of the only finite resources we have; time. Still only 24 hours in each day, trust me I checked, and while I didn’t sleep too many of those 24 hours while away, there just wasn’t enough time left over after days and nights filled with time with friends, family and most of all grandkids on top of keeping up with Project Goldilocks both back at Naval Yachts and on a daily basis stateside ordering, shipping and packing literally hundreds of pieces and kilos of equipment and supplies to take back to Antalya.
I know, I know, ……….. excuses, excuses. But let me plead my case just a wee bit by showing you just a few of the reasons why my time just got away from me:
Our now FOUR year old Grandson Liam
Three year old Granddaughter Blair
And Five year old Brynn
CanAm Thanksgiving dinner Building shipping crates Filling shipping crates Trucking crates to the shipper in time. All 392 kgs/864 lbs for this one crate alone.
Introducing Baris and Dincer to the USA and FLIBS (Ft. Lauderdale International Boat Show) for their first time.
Pausing long enough to take in another gorgeous Vancouver sunset with dear friends.
Well, you get the idea. All just excuses I know, but you might admit some pretty darn cute and great ones and I wouldn’t have it any other way. But let’s get back to boat building shall we?!!!!!
As you may have noticed in the title, I’m going to cover TWO weeks of progress for you here, spanning October 28th through November 15th, 2019 so hang on to your hats, grab a tasty beverage and let’s go fly through Naval Yachts shipyard and see what Team Möbius has been up to.
Let’s start with Plumbing Progress for a change and check in with Cihan to see what he’s been up to.
Down in the Basement he has now mounted and plumbed one of two 150L/40 USG black water holding tanks, This one in the Basement is for the Guest Head and ….. …. this one waiting down on the shop floor will soon be mounted in the Forepeak to service the Master Cabin Head.
These are complete systems with a super reliable Dometic diaphragm pump, odor filtered vent and all the built in fittings.
Next to the BW Holding tank Cihan as also mounted the vacuum generator that is part of our beloved VacuFlush toilet systems. We had these on our previous boat and worked flawlessly for the 14 years I had her and we really love how well they work. Here is how these two components sit in the Basement, up against the WT Bulkhead with the Guest Head immediately on the other side so very short pipe runs even though these VacuFlush systems are built to have very long runs with no problem. As we do with all the equipment, the Holding Tanks and Vacuum Generators are isolated from the boat by mounting systems that keep them clear of the floor as in this case and also allow us to create vibration absorbing soft mounts where needed such as on the Vacuum Generator to ensure no noises from the pumps can transmit through the hull and interior. These two diaphragm bilge pumps are another example of how we keep all components isolated from the boat.
For those unfamiliar with VacuFlush it is a system very similar to the way the heads on airplanes work. The Vacuum Generator creates a vacuum between itself and the underside of the toilet bowl and so when you step on the foot pedal beside the toilet everything in the bowl is instantly pulled through the sanitation hoses, through the VG and into the Holding tank. The Holding tank then has its own diaphragm pump to extract the contents out to the Sea Chest or to a pump out connection on deck for shore side pump outs.
This manifold is part of the plumbing for the pump out of both the Gray and Black Water systems. Given our typical sailing style we don’t usually need to use shoreside pump out facilities and can discharge when miles off shore through our Sea Chests so this manifold allows us to select between Sea Chest and pump out for the BW.
More of Cihan’s handiwork in the Basement on the various Bilge pump plumbing. Larger 40mm/1.5” hose is for the high volume Bilge pump system and the smaller 25mm/1” clear hoses and those two diaphragm pumps are for slurping up any small amounts of water that might find its way into those “gutters” formed where the tank tops are curved down so they can be welded perpendicularly to the hull sides. Makes for a very tidy, effective and efficient bilge system. And Cihan makes it all the neater with his careful routing of all these hoses through the “super highways” of cable trays running throughout the boat.
Our awesome Cabinetry team of Omur, Selim and Ömer have been keeping up their always impressive progress as they build the cabinetry for the Galley, SuperSalon, Guest Cabin and Office areas so let’s go see what they’ve been up to the past 2 weeks.
One of the newest cabinets to get started are the ones for the freezers and fridges. A bit hard to see through the blizzard of clamps perhaps but this is the cabinet for the two 130L/35USG Vitrifrigo fridges which will slide snugly into the two large openings and with two storage drawers below.
Yesim provided this quick render so you can see how all four units will look along the Port side of the SuperSalon. This is a much more efficient and pleasing design that what you may recall seeing in previous renders where we have moved the two freezer drawer cabinets forward and tucked them out into the large space under the side decks. Keeps everything nice and low and makes both the fridges and the freezers much easier to access when you open them.
Here is the cabinet for the two drawer freezers being assembled in the Cabinetry shop. This helps to see both the placement of these cabinets and the relative size of the two fridge units and drawers. And these two freezer drawers. You can see how far back this space extends under the side decks and we are taking maximum advantage of this voluminous area on both sides of the SuperSalon. You’ll see more examples in the coming weeks as those cabinets go in. The cabinetmakers amongst you will appreciate this sectional shot of the back edge on one of the walls of the fridge cabinet showing how the exposed edges are all built with solid Rosewood for both longevity and nicely radiused corners throughout. The marine plywood you see is that new sustainable and very light weight Poplar based product that is working out eXtremely well to dramatically reduce the weight of all the cabinetry and provide a super stable substrate for all the cabinets.
and of course Wayne’s infamous “Blue Horizon Line & Handhold continues throughout this and all other interior areas of the boat.
Standing with your back against the Fridge cabinets and looking across to the Starboard side we see that the dining settee is now all fitted in place. Those two doors in the seat back provide access to that voluminous area under this side’s decks. Standing forward near the Main Helm station and looking aft this shot provides a sense of scale and location for the dining settee relative to the Galley. Not all of the action and progress is happening in the SuperSalon as Ömer and Okan continue to work on the cabinetry down in the Port side of the Guest Cabin area.
Okan is test fitting the tall cabinet as you do down the stairs to my Office area. This and the cabinet that will soon fill the space to the right will be home to the Aft electrical distribution panel, circuit beakers, etc.. With that tall cabinet out of the way you get a better shot of the generous amount of “clean workbench” area I will have in this Office that flanks the corridor leading to the main Workshop and Engine room. You can see this WT doorframe at the very top of this photo behind Ömer’s back. Never too many drawers and storage on a workbench or office right? Plus there is another whole set up above. The large opening below the center of the desktop provides space for a swivel out seat when I’m working here.
Last but never least for this week’s Progress Update let’s see what Uğur and Nihat have been up to with several aluminium projects onboard.
Nihat made quick work of fabricating and then mounting the circular chain locker. Uğur laid down a nice MIG weld inside and outside the seam. They welded in the slightly dished towards the center (for drainage) bottom plate and the Chain Bin was ready to head to its new home in the Forepeak.
Could almost be mistaken for a work of art don’t you think? Nihat and Uğur made a series of brackets to attach the Chain Bin to the frames in the Forepeak, Leaving plenty of space for me to be able to climb in there to clean things out in the future. Looking underneath shows the solid framing to support the significant weight of 100-150m/330-500ft of 13mm/ 1/2” Schedule 4 chain.
The Chain Bin is completely self draining and that pipe exiting the center of the bottom will lead over to the exiting Sea Chest on the left.
Another new project involved these disks of aluminium and rubber. Can you guess what these are for? Getting any warmer with this upside down view? How about if I let Yigit show you the completed prototype? Correct! These are the adjustable lids for every circular vent penetration in the deck. XPM boats are self righting and so all sources of water entry must be able to be shut off either manually or automatically. Most of these adjustable vent lids are located inside the Dorade Boxes on the Foredeck which you can see in this render. The flexible cowls can be rotated 360 degrees and they catch any breeze and direct that fresh air down into the Dorade Box area below and any water that might come in drains out through slots all along the bottom edge of the Dorade Box and the deck. The fresh air flows down into the interior through the Vent pipe when these adjustable lids are well up above the top of the pipe and in almost all situations this ensures great ventilation in almost any weather or sea conditions as the water is kept out. However if conditions were really severe or for any other reason you wanted to close off these vents you just reach up from inside the boat and turn the threaded rod to bring the lids down and sealed tight against the top of the vent pipe.
Another good example of the KISS approach we take wherever possible. Uğur, Okan and Nihat were also busy finishing the Paravane A-Frame booms so they erected some scaffolding to get up to the top of the 7m long Paravane booms to fit and weld the hinge assemblies. This is the hinge half at the end of the angled pipe of the A-Frame assembly which …… mates with this swivel that attaches to the beefy Rub Rails. In the midst of all this they also found time to complete the building of the rudder which also now looks to me like artwork as it gleams in the sunlight streaming into the shipyard. Prior to being assembled and welded the Rudder Post spent some time in the machine shop having the hole for the Emergency Steering Tiller machined through the top and …. the keyway slot milled out for the Tiller Arm to attach to once mounted in the boat. The Rudder Blade still needs some finish work on the welds and then the whole blade assembly will be primed, faired and sanded very smooth prior to being eventually covered with foul release paint along with all the other parts of the hull below the Water Line. For now though it is all ready to be fitted into the hull with its pair of self aligning bearings.
Whew! I’m tired just writing about all that work.
Again my apologies for keeping you all waiting and I’ll now go write up the Weekly Progress for this past week so that you are all caught up with the work of Team Möbius.
Our time away visiting friends and family and getting in some much needed Gramma and Grampa time was priceless and we are also happy to be back here and bear down on getting Möbius ready for Launch as soon as we can make that happen.
Thanks for choosing to spend some of your time joining us on this adventure and PLEASE do add any and all comments and questions in the “Join the Discussion” box below.
See you again next week.
PS. Special thanks to Yigit and Uğur for taking most of these pictures for me while I was away. Thanks guys!
For this past week, work on our XPM78-01 at Naval Yachts was focussed on the Cabinetry in the Galley and Guest Cabin and aluminium work on the rudder, chain bin, Dolphin watching seats and more. Here is a Show & Tell summary so you can see for yourself.
Let’s begin with these beauties. Can you guess what this is? Will it help if I show you where it is going to go?
These are the eXtremely strong padeyes on each of the aft corners for attaching a drogue or perhaps a stern anchor line.
The hole has a 316 SS bushing pressed into it to reduce the wear from the shackle used to attach the drogue.
A drogue is one of the ways of helping control a boat in eXtremely large seas and is the opposite of a sea anchor as this illustration shows.
John over on the Attainable Adventures blog, which is a treasure trove of great information for blue water sailors, has this well done sketch showing the basic operation of a drogue and how it can help control a boat that is roaring down huge breaking waves by slowing it down and reducing the likelihood of the bow digging into the wave ahead at the bottom of the trough and pitch poling over itself. NOT a good thing or an experience we ever hope to have! But having this kind of emergency equipment aboard is one of the ways we implement our strategy of “readiness for the unexpected”. As you might guess from looking at that sketch, trying to slow down almost 45 tons of boat racing down mountainous waves in these kinds of conditions puts an unimaginable amount of force on these systems and requires an equally eXtreme attachment point to attach the boat to the drogue. Hence this design we came up with for the padeye we would use if we ever needed to deploy our drogue.
Peering inside the hull you can see the substantial amount of the padeye that sits inside and will be heavily welded to the frames on this aft corner of the hull. Standing back you can see how this fits into the Aft Deck and Swim Platform layout.
And this is the matching padeye on the other side.
AFT PORT SIDE STANCHIONS:
Uğur also finished off the last of the stanchions to be installed, these ones on the Aft Port side which will be removable as they only go in when the Tender is off the deck.
Uğur has had LOTS of practice with all the other stanchions and their pipe sockets which are welded through the beefy Rub Rails so he soon has these last three stanchion sockets welded into the Rub Rails……. …… and presses the black Delrin sleeves into each one. He has finished fabricating the stanchion posts and they are now test fitted into their respective sockets.
DOLPHIN WATCHING SEATS:
Moving up to the bow, Uğur ticked off another job there with the mounting of the two Dolphin watching seats on either side of the bow pulpit railings. We came up with this hinged arrangement so they can be easily flipped up and out of the way when anchoring. Like this. I am still sketching up different ways of securing the seats when they are folded up. Perhaps in this position where I would need to have a way to secure the hinged vertical leg. Which wouldn’t be neccessary in this position where the leg sits tight against the seat rail but it presents an unattractive safety hazard with the part sticking up above the top rail.
Or I may just use some quick release pins to be able to remove the leg entirely and then come up with a nearby spot to hold it.
Stay tuned to see what emerges as the solution and by all means send in your ideas too.
Omer continues to apply his craftsmanship to the Guest Cabin and has now finished the slide out couch/bed assembly and moved on to building the headboard of the bed and the bookshelf unit that wraps around the forward Starboard corner of the cabin.
He has fitted this little angled cupboard between the bed and Christine’s desk which will be handy for both Guests and Christine to use. It will have a door on it next. Next he test fit the back of the couch. The space below is to allow the large bottom cushion/mattress to slide all the way inside when it is folded up in couch mode and keep the depth of the bottom of the couch a good size. Then he installed the framing for the top shelf and there is similar framing hidden down at the bottom. The tape indicates that there will be removable access panels there so I can easily access the water manifolds and other systems that are back there if ever needed. The carefully laminated top surface goes in next and spans the whole distance from the desk over to the forward wall that is the WT Bulkhead with the Basement on the other side. Which will look like this. This recess is where the back cushion will fit partially inside and held in place with in couch mode. Half the thickness of the cushion will be inside this recess and have extending out.
With a matching arrangement on the other side. With the couch/bed all fitted in place Omer turned his attention to the L shaped bookshelf unit that wraps around the forward corner of the Cabin. It all starts out being very simple with the cutting of these top and bottom boards after they have been laminated with their Rosewood surfaces. Renderings are so useful in helping with that phantasmagoria I mentioned in the previous posting where the virtual reality blends with the real reality and for those of us doing this every day you see the finished whole all the time no mater if you are looking at a largely empty space or those two L shaped boards in the photo above or this rendering on the left. This helps to visualise both the relative size and shape of this bookshelf. This is the bottom side of the bookshelf with Rosewood on the top and bottom surfaces and then there will be a white shelf in between which you can see in the rendering above.
Not to be outdone Omur and Selim have been eXtremely busy working up in the Galley on the somewhat complex set of cabinets with over 18 drawers so let’s check that out next. Yigit is aboard frequently monitoring the progress and helping me keep the thousands of little details all straight. Yigit also looks after much of the ordering of all the materials and equipment from our many suppliers so his phone is his constant companion. The cabinet in the upper area is the six drawer unit that goes in where Yigit is standing.
Quick jump to the virtual world of renderings to refresh the layout of the overall Super Salon with the Galley in the upper right corner.
Selim on the far left is standing inside what will be the forward corner of the Galley cabinets as he and Omur start getting this cabinet perfectly aligned with the others and precisely leveled.
Notice how the white epoxy painted boards under the bases of each cabinet have been painstakingly leveled using all those little wood wedges. These foundation boards also raise the cabinets up to the same height as the 40mm/ 1.6” rigid foam insulation which will eventually cover the entire floor and have the PEX tubing running through it for the in-floor heating. Here we are looking down inside the cabinet that will have the double sink installed in the far right side. The cut out on the back is to provide me access to the quite large volume area that is underneath the side decks. In addition to all the tank vent and fill hoses you can see we will have other equipment in this area such as the air handlers for the AirCon system so having access all along this large volume area goes towards our goal of low and easy maintenance. Next piece of this jigsaw puzzle is the cabinet on the left here for the induction cooktop and Smart Oven (combo microwave, convection, grill ovens). Fits perfect! For those of you who have been following for some time this will now help you visualise and understand why there is that white-stepped connector framing between the upper corner of the Guest Cabin down below and this far end of the Galley where the stove and oven fit in.
The cupboard in the middle here is sized for a standard dishwasher or a two drawer dishwasher to slide into but we prefer hand washing so this will instead be filled with two large drawers for pots and pans and the like. Looking across that dishwasher cabinet to the “peninsula” cupboard opposite shows the 7 drawers it contains. The tall skinny one in the middle will be like a drawer with no sides and pull out to reveal a set of shelving racks to provide easy access from either side to containers of things like spices. Maybe something like this for example. OK, Galley cabinets are all in place, time to move on to the adjoining L-shaped settee and dining area so they get started putting down the foundation frames and shimming them to be on eXactly the same level as the other cabinetry.
This is about how this area will look when standing over on the far Port/Left side looking across. The table is on a pedestal which has some very cool hardware I found that allows it to move in all three axis: Z up/down, X fore/aft and Y left/right. This gives us total flexibility to have this table at just the right height and position to use as a dining table, coffee table or additional Queen Bed. But WAIT! There’s more!
Look what showed up late Friday evening as I was leaving the shipyard!
Without cheating by zooming in, can you guess what this sturdy crate contains?
It arrived via air freight direct from Vancouver if that helps?
Yup, all of the many components that make out our rock solid steering system along with the controls for the Gardner engine and the Nogva CPP servo gearbox. As per the label here this all comes from Kobelt which is based in one of my old home towns of Vancouver not far from where I did some of my teacher training at BCIT many decades ago. I worked closely with our designer Dennis and Lance and his team at Kobelt for over two years to design the Goldilocks just right steering for our XPM78-01 so you can imagine how happy I was to see this big beautiful crate full of steering goodness finally arrive.
Even though it was very late and Yigit and I were the only ones still in the yard, I just couldn’t resist taking a peek inside a few of the boxes so I’ll share two with you.
This is one of the pair of double acting 75mm/3” ID hydraulic cylinders that will move the rudder and steer the boat. Each one is sized to be able to fully steer the boat in all conditions so a double redundant system. And then check out one of the pair of Accu-Steer HPU400 hydraulic pumps which will provide all the hydraulic pressure to run those cylinders. These are massively strong and weigh in at 44kg/95 lbs each and are an integral part of what I’m sure is going to be an awemazing steering system in our XPM78-01 Möbius.
Much more to follow on the whole steering system in upcoming Weekly Updates as the installation begins and I will also be posting some Tech Talk articles where we can dive into all the details of the whole steering system design.
And th-th-th-that’s all for this week that was October 7 to 11 2019.
We really do enjoy sharing this whole adventure with you and want to thank all of you who take the time to read these. Special thanks to those of you who contribute comments and questions in the “Join the Discussion” box down below and hope that more of you will do the same.
