Mr. Gee is Cagey & Exhausting Progress Update XPM78-01 Möbius Jan 11-15, 2021

Another busy week for Team Möbius as we all focus on getting her finished and ready for her Splash Day first kiss with the sea, which we are now counting in weeks rather than months or years, so exciting times here at Naval Yachts to be sure.  As is often the case near the end of an eXtremely big project and certainly at the end of Project Goldilocks, most of the work is on all those “small jobs” chasing down all the loose ends from previous work installing all the systems, cabinetry, propulsion, etc.  And as most of you would know from your work on projects it is the last 5% of a job that seems to often take 50% of the time!  However, good progress is being made and I will take you on a whirlwind tour through all the little things that got done this week which add up to be an eXtremely BIG deal as it gets us another week closer to Launch Date.

So strap yourself in and hang on for this week’s Show & Tell tour of the Good Ship Möbius for the week that was January 11-15, 2021.

HELMS:

Llebroc Upper Helm ChairYou may recall from reading previous posts that we have been very busy finishing off lots of those “little jobs” to complete the Upper and Lower Helm Stations and that continued this week. 

This is the Llebroc Tradewinds CX High Back helm chair that will be our perch when piloting Möbius from the Upper SkyBridge Helm and Nihat and Uğur got that all mounted and through bolted this past week.
PXL_20210111_133056567We needed to wait until the TreadMaster had all be glued down to all the aluminium floors in the SkyBridge and then we could mark out the exact location of the 6 through bolts for the base of the pedestal.
PXL_20210111_152910361.MPDirectly below this Upper Helm Chair base is this area above the Galley so Nihat removed the 50mm/2”  EPDM insulation foam to expose the area where the supporting plates and through bolts would go.


FastMount standard ClipThis is a good example of why all the panels on the ceilings and many on the walls are made to be easily removable by using FastMount clips which are the White dots you can clearly see against the Black ceiling framing in the photo above.  Being able to remove any panel in a few seconds is an eXtreme time saver for such jobs.
PXL_20210111_152902953There can be a tremendous amount of force exerted on that base when a good sized adult is perched way up on top of the Helm Chair in rough seas so Nihat & Uğur installed some 20mm AL plate on the underside of the AL floor plates and then ran the through bolts from the pedestal base to sandwich the whole assembly and create an eXtremely solid pedestal for this Upper Helm Chair.
PXL_20210111_152922589.MPAs is so often the case with these “little” jobs, all the time and work is in the preparation and the actual installation goes very quickly.  So once they had all the prep work done with the support plates and drilling the holes it didn’t take them long to torque down these six 316SS C’sunk bolts and the Upper Helm Pedestal was all done and ready for the adjustable base plate and slider of the chair to fit over the top of the AL piston you see here.  This piston has a powerful gas lift cylinder inside that makes it easy to raise/lower the Helm Chair about 30cm/12”.
PXL_20210111_133149816In front of the Upper Helm Chair, this custom made Switch Panel for all our external lights finally arrived and fit like a glove in the opening below the Standard Horizon GX600 VHF-AIS.
PXL_20210111_102538061Hilmi had already installed all the wires so it did not take him long to get all these switches wired up.  We tested out all the lights and everything worked just as planned.
PXL_20210111_064947231Such as these Green Navigation Lights that Hilmi is checking out here on the Starboard/Right side of the SkyBridge coaming.
PXL_20210111_065005679Red Nav Light on the Port side working just as well.

BTW, a fun way to remember the Red/Green orientation is “There’s no Red Port Left”  (thanks for the correction Max!)

TreadMaster on these side decks is all ready to be glued down which they also completed this past week.

PXL_20210111_133120077Christine and I installed the two 24” touch monitors as you saw last week and there are a few more “little jobs” need to be looked after but this Upper Helm Station is nearing completion now which has been great to see.
PXL_20210111_133406608Similar story down below at the Main Helm where we also installed the two 19” touch monitors last week and this Helm is now also getting close to finished.
PXL_20201123_080219974.MPThis is the Llebroc Bandera Series 2 Helm Chair which, similar to the Upper Helm Chair, needs to have its pedestal mounted and through bolted in the floor.
PXL_20210112_093059795We needed to wait until Ramazan had finished installing all the Ado LVT vinyl flooring and then layout the location of the solid block floor that had been installed here for the through bolts to go through the 50mm/2” thick insulated and heated floor. 

Drilling and installing these through bolts is a bit tricky due to all the cable trays filled with electrical cables running underneath this floor in the Basement, but we lowered the cable trays and drilled all the holes with no problem after lots of careful measurement.

This is where we left off on Friday so Uğur and Nihat will pick up here when we all get to work Monday morning.
PXL_20210112_093041739Just behind the Main Helm Chair we had to do the same kind of layout and prep for through bolting this Zwaardvis Triton Deluxe adjustable pedestal for the Dinette Table.
PXL_20210112_093055787In addition to the Up/Down adjustment of the pedestal itself you can see here how the Zwaardvis T-System XY slider bolts on top and allows us to move the table fore/aft and left/right by 200mm/8” which enables us to put the Rosewood table in the Goldilocks just right position for eating/working, lounging of made down into a bed.  The little Black unit on top will be fastened to the underside of the table and you just pull that Black lever and the cable releases the “brake” while you slide the table in the XY axis you want and then release to lock the table in place. 

Very KISSS – Keep It Simple Smart & Safe!
PXL_20210111_153157483.MPBy Friday Faruk, Orkan and Ali had finished up the remaining “little jobs” with the TreadMaster non-slip surfaces.  Both Side Decks and the front platform in front of the hinged Solar Panel bank is now all completed.
PXL_20210111_153121429.MPAs is this small area around the Lewmar EST65 Warping/Kedging winch.

OTHER ELECTRICAL JOBS

PXL_20210111_153126683Our head Sparkie Hilmi had a busy week as well. 

He installed the Black Foot Switch for the Warping/Kedging winch above, so one more little job checked off the punch list.
PXL_20210111_102527822Finished wiring up all the components in the Upper Helm Station.  Kobelt WalkAbout remote control box in the upper Left corner, Nogva CPP clutch controls below it and Horn, Engine Stop & Start buttons on the bottom.

PXL_20210113_111533388Looking through the WT door off the Aft Deck and peering into the dark space above as you walk through into the SuperSalon, you might be able to make out the neat little alcove up above that Hilmi and Christine worked on this past week.
PXL_20210113_111509509Here is a closer view with the upholstered panel removed to show the components installed in this well protected space.  Far Left is the Axis M7104 Video Encoder that puts our non IP cameras onto the network,
PXL_20210113_111516129In the middle is one of several Planet Industrial 10/100TX Ethernet switches and the incredible Kingdel i9 9th gen mini computer that Christine put together to be our Boat Computer #2.

HOUSE BATTERY BANKS

PXL_20210115_130946525Yesterday (Friday 15th) Hilmi and I spent some time down in the Basement working to finish off the installation of the 24 FireFly Carbon Foam batteries which make up our 1800Ah 24V House Battery.
PXL_20210115_131014986.MPHilmi has all 24 batteries wired up in their 6S4P configuration where six 4V batteries are wired in Series to create four 24V @ 450Ah banks which in turn are wired in Parallel to create a single 24V @ 1800Ah House Battery which gives us a total capacity of 45kWh to power all the AC and DC circuits onboard.  While we can safely take these Carbon Foam batteries down to 20$ SOC State of Charge, we will typically not take them below about 50% SOC so as to maximize their cycle lifespan and still give us up to 900Ah or 21.6kWh to keep us safely and fully powered up at all times.
PXL_20210115_132643694Before we look after the last step of organizing and supporting all the cables, Hilmi, Ramazan and I worked on this very KISSS way of holding each of the 24 4Volt cells in solidly in place under all conditions.  Each 4V cell/battery weighs 43kg/95lbs and by wedging each battery in place using these composite foam pieces you see in these photos.
PXL_20210115_132707875Right beside Möbius, Naval is building a big fancy 20m catamaran out of very high tech composite materials and this foam board was all left over “scraps” that caught my curiosity so I tested out some samples and this stuff is awemazing! 

It is literally light as a feather and I can beat it with a sledge hammer and not put a dent in it!  I’ve tried soaking it in water, vinegar and acetone with no absorption or other affects so I had an Aha! moment and thought this was the Goldilocks solution for a KISSS battery hold down system you see here.
PXL_20210115_132654215Along the sides, while difficult to see here, a two stepped piece of composite foam snuggly wedges in place between the sides of each pair of batteries and the aluminium tank sides and the thicker upper stepped part holds the batteries down by the ledge along the outer edge of each battery case.
PXL_20210115_132650957Down the middle a T shaped piece of composite foam is wedged into the 40mm/1.6” air gap where the sides of the batteries meet.  If you look closely (click to enlarge any photo) at the foam piece on the far Left, you can see how the T cut out fits on top of the ledge on the Blue plastic battery case.  When the AL plate lids are bolted on top this will squeeze the batteries tight against the AL floor down at the 25mm ‘’/ 1’ thick Keel Bar

I’ll be back next week to show you how we have organized and tied down all these big 25mm2 / 4/0 cables and then bolt on the 6mm AL cover plates with gaskets to seal the whole battery compartment which is then vented with thermostatically controlled fans to keep the batteries cool and well vented.

LIFELINES!

PXL_20210114_133143233Christine has been working onboard Möbius every day for the past few weeks now and took on one of the larger jobs remaining; installing all our Dyneema Lifelines.  I’m not sure if she is holding on out of pride of her work here on the Aft Deck or to help keep her tired little body upright after a grueling week.

We are using Dyneema for all our lines and rigging as it just SO superior to standard lines and Stainless Steel twisted wire being stronger, safer, kinder to the hands, easy to inspect and monitor.  Christine is going to do a separate blog post here with all the details so I will leave you to read that when it goes up in a few days.


Being as pleased and proud of her as I am though, can’t resist just a few photos of her handiwork to whet your appetite for more.


PXL_20210113_114221872Simple eye splice where each Lifeline begins with this “Luggage Tag” style attachment to the 40mm/1.6” thick walled AL stanchion posts.
PXL_20210114_133300285The top Lifeline is 90cm / 36” above the deck and the bottom one is a custom Goldilocks Just Right height to help keep our stubby legged Barney the Yorkshire Terror onboard.
PXL_20210113_114244534Where the Dyneema Lifelines simply pass through a Stanchion these short lengths of 10mm / 3/8” AL pipe have been welded at the height of each of the 3 Lifelines.
PXL_20210114_133209301For Lifelines that we need to remove regularly, she splices a Pelican Hook on the other end with a simple endless loop around the end gate stanchion pipe.
PXL_20210114_133228050Along the length of each Lifeline, to provide adjustment and re-tensioning over time, Christine has spliced on two Black aluminium “donuts” and then lashed between the two with smaller diameter Dyneema.  This one is just temporary while we are testing out the layout but will give you an idea how this system works.

SuperSalon is Floored!

PXL_20210111_064335000Ramazan has quickly become a Master at installing the Ado LVT vinyl flooring we are covering all the floors in all three living compartments on Möbius.  For orientation of this photo I am standing about where the Main Helm chair is looking Aft at the stairs leading up to the Aft Deck.  Ramazan has about half of the Ado LVT vinyl planks installed on the Right side in front of the two door style 130L Fridges in the back and 2 70 liter drawer freezers in the foreground.  The bare plywood rectangular piece on Ramazan’s Left is the hinged hatch that lifts up to access the stairs down into the Basement under the whole SuperSalon floor.
PXL_20210111_064306051.MPHere is what it looks like from the opposite end, standing in that WT door off the Aft Deck looking forward to the Main Helm at the front of the SuperSalon.  Galley is partially visible on the far Right.
PXL_20210113_111549426.MPA few hours later and that Basement Hatch is almost fully covered and Ramazan did a fabulous job having it blend in almost invisibly to the rest of the floor.
PXL_20210112_125857110Main Helm and Dinette Table floors all laid down and I’ve started to lay out the locations for the pedestal bases of the Helm Chair and the Dinette pedestals.
PXL_20210112_125852600Flooring all done in the Galley now.
PXL_20210114_124241646With the LVT flooring all done in the Master Cabin and the SuperSalon, Ramazan transferred his attention to the Corridor and Guest Cabin area which will likely the the most time consuming as there are 10 tank access ports he needs to lay the flooring around.

Here in the Corridor that connects the stairs up at the top of the photo coming down from the SuperSalon, to the WT door into the Workshop which is where I’m standing to take this photo.  He pulled up the temporary plywood covering that has been covering this area so he could level off the tops of the Blue rigid foam board for the final marine plywood to go on next.  Easy to see how PEX tubing for the In-Floor heating is snaking through the foam and the aluminium tape helps reflect the heat upward through the plywood.
PXL_20210115_105407266.MPPlywood is now screwed in place to the wood frames underneath and Ramazan has started to lay down the Ado LVT vinyl planks.

Stay tuned for next week’s episode where he will likely finish off all the vinyl flooring.

Mr. Gee gets Cagey!


Mr. Gee cage   exhaust support modelYou may recall from last week’s Progress Update that I had designed this pipe rail or cage setup attached to the four motor mounts I had designed months ago and work continued on this week.
PXL_20210105_132404350Here is where we left off last Weekly Update with the front and rear rails or “staples” that Uğur and Nihat had installed.
PXL_20210111_063820393On Monday, Uğur and Nihat finished off the “cage” by bolting on the two lengthwise tie rods to complete this very rigid cage around Mr. Gee.  As with so many elements on Möbius this serves multiple purposes, one is to provide a safety element when we are doing our hourly engine room checks on a passage and a sudden lurch in the boat’s movement might cause you to loose your balance and reach out to grab one of the hot or moving parts of Mr. Gee.  Now this “cage” provides you with a safe cool hand hold all the way around.


PXL_20210111_063824172.MPSecond purpose of this pipe cage is to provide the frame for the four support rods that need to go up to support the dry stack components of the Halyard exhaust system.  These four “ears” or tabs have been welded on to provide the lower attachment point for those four SS support rods.
PXL_20210114_134024345Cihan and Mesut fabricated four of these SS support rods in no time by welding some SS slugs into the end of each SS pipe and threading it for the Heim joints that would go in each end.
PXL_20210114_134033887I am just test fitting the Heim joints here so the SS lock nuts are not yet in place but you can see how this simple setup creates a Goldilocks support rod that is of course all very KISSS Keep it Simple Smart & Strong.
PXL_20210115_101831712Here is what it looked like as we shut down yesterday.  Next week Cihan will install the front two supports but already the exhaust dry stack is eXtremely solid and I can barely make it move when I grab it and shake it for all I’m worth.
PXL_20210114_150011125Two other important “little” jobs Cihan and I worked on this past week were the mounting of the Morse cables to the Nogva CPP Pitch lever and the throttle lever on Mr. Gee, and the solenoid for the shutoff lever on Mr. Gee. 

I whipped up this little sketch on my new favorite drawing board; cardboard!  No work of art and rather embarrassing for a former Draughting/Drafting instructor but it works well to outline my basic ideas and communicate them with Cihan with no problems given my poor Turkish language skills.


PXL_20210114_143123672I just love working with Cihan and everyone on Team Möbius because it is such a collaborative relationship.  I did that initial sketch you see above and discuss the key parameters with Cihan and ask him to run with it and build whatever he thinks will work best and is easiest for him to build.  This is the modified design he came up with and fabricated in minutes out of some 10mm / 3/8” aluminium plate.
PXL_20210115_101941176The purplish colored Morse cable on top here transfers the mechanical movement from the Kobelt electronic Actuator box up above on the ER wall down to thee throttle lever on Mr. Gee to change his RPM and then the 24V solenoid underneath moves the engine shut off lever below.

A similar Morse cable comes down from the other side of the Kobelt Actuator to move the Pitch control lever on the Nogva CPP Servo Reduction gearbox but I failed to get some photos of that.
PXL_20210115_101947000Her is a better angle of the finished result of the Throttle cable on top and the Shut off solenoid below. 

  • Two more jobs checked off the list!
    PXL_20210115_101923504Another prime example of how these “little” jobs take a BIG amount of time was finishing off this very busy area around Mr. Gee’s oil filter.  The bronze block on the Left has four fittings in it, the top one I’ve installed one of the two direct oil pressure gauges and then the Black line below it takes the pressurized oil directly to the valves in the cylinder head.  The bottom two outlets I have just plugged off for now but will soon have an oil pressure alarm sensor installed.
    PXL_20210115_101848653On the Right side of the big cast Oil Filter canister is the Black oil pressure adjustment valve and then that beautiful bronze oil temperature thermometer and a 2nd oil pressure gauge on the far Right.  The reason for two oil pressure gauges is that the one on the Right measures the oil pressure when it is highest coming directly out of the oil pump inside the crankcase whereas the one on the far Left measures the oil pressure at the far end of the line just before it gets pumped back into the crankcase.  This setup allows me to instantly see the difference from start to finish of the oil pressure to the engine and enables me to quickly spot any problem long before it advances.
  • There are also digital equivalents in the form of temperature and pressure sensors that will put this data onto our N2K network where I can log it by the minute and have a full history of all these metrics being logged every second of every day.


And that’s a wrap for the week of January 11-15, 2021 people!  Thanks so much for getting through yet another one of Wayne’s rambling Weekly Progress Updates and in spite of my pathetically long response time to them, PLEASE do add your questions and comments in the “Join the Discussion” box below.

I hope to see you again next week.

There will be NO Slip Sliding Away on Möbius! XPM78-01 Möbius Weekly Progress Update Jan 4-8, 2021

And 2021 is off to rapid start as the first week of the year has already whipped by me in a flash.  Very busy times here as we all push to finish XPM78-01 Möbius and get her in the water by the new target Launch Date of February 12th!  Which BTW, is now only 33 calendar days and 25 working days from now.  Yikes!!

However, as we all learn over time, deadlines are good things to help us keep our eyes on the prize and get things done so as to ensure that there is no “Slip-Sliding Away” of our Launch Date!  Therefore, I am going to stick with using this fixed Launch Date to help keep the positive pressure on all of us on Team Möbius to “get ‘er done” and as my 4 year old granddaughter Blair says (with gusto!) “Let’s DO this!”

I’ll take that advise to heart with my introduction to this Weekly Progress Update and jump right into this week’s Show & Tell of what all happened aboard the Good Ship Möbius this past week of Jan 4-8, 2021

Non-Stick on the Bottom:


PXL_20210104_121016219

Continuing the very rewarding trend of late of hitting lots of different milestones of this build, work began this week on preparing the bottom of the hull for its foul release bottom paint.  First step was to clear out all the equipment and materials which had been accumulating underneath the hull on the shop floor.
PXL_20210104_121024683.MPIt helps to have a forklift of course so it didn’t take too long to move everything elsewhere at Naval Yachts and have a clear floor space under Möbius to work on.
PXL_20210105_064646565Next up was to get rid of the short little hull support posts and replace them with these longer steel tubes that connect just under the Rub Rails and slope down to the floor where they are secured into the concrete with long lag bolts.

You’ll note too that the upper part of the hull sides have now been covered in plastic to keep their freshly sanded surfaces clean.
PXL_20210104_111758312.MPThe two newest members of Team Möbius, Ali kneeling on the Right and Mehmet standing on the Left, get to work grinding down the welds below the waterline and removing the layer  of Aluminium Oxide Al2O3that has formed since these hull plates were first welded in place over two years ago. The automatic and rapid formation of Al2O3 is one of the big benefits of building hulls from Aluminium as it is a very had and durable protective layer that prevents any further oxidization or corrosion.  However Al2O3 is equally good at “protecting” the hull from paint, which is part of the reason why we are leaving all the exposed aluminium on Möbius unpainted. The one exception is below the waterline where we need to prevent marine growth from forming as this creates a lot of drag on the hull as it slides through the water.
PXL_20210105_072426269.MPSo you need to remove all the Al2O3 before the first coat of epoxy primer goes on.  This is the first round of removing the Al2O3 and then just before the first coat of primer is sprayed on, they will give it a light sanding with orbital sanders and a wipe down with Acetone to make sure the AL surfaces are completely clean and oxide free so the primer will bond well
PXL_20210105_074437093

The only item below the waterline that does not get painted is the big 1m OD beautiful Bronze Nogva CPP propeller, though later on, it too will get some special treatment to prevent fouling as even the slightest bit of grown or roughness on a propeller blade causes severe reduction in transferring power from the prop to the water.
PXL_20210105_074446979The special tube we cut through the Rudder can now be be filled in so Uğur tacked this elliptical AL plate to block off the hole for now.  Whenever we might need to pull out the prop shaft, this hole allows me to do so without having to remove the Rudder which can add a lot of time to the prop shaft Re & Re.  This will get covered with some epoxy filler and sanded flush with the surface of the Rudder plates as a super slippery Rudder also helps a lot to increase the efficiency of the Rudder and Steering overall.
PXL_20210104_132711290Another important part of the preparation for the bottom paint is taking off the upper edge of the “Boot Stripe” at the very top to make the transition from the bottom paint to the unpainted aluminium above.  This is made SO much easier now that we have laser levels to use rather than the laborious process of measuring every few feet as I’ve had to do in the past to establish what you hope is a level straight line.  In keeping with the “lean & mean” exterior esthetic, the Boot Stripe and the bottom paint will both be Black but the Boot Stripe will be glossy Black Polyurethane whereas the Bottom Paint will be the matt finish of the silicone based International InterSleek 1100SR


For those not so familiar with bottom paints, most boats use an Anti-Fouling type of paint which prevents micro organisms from growing on it by having various biocide chemicals such as copper, tin and now more modern toxins which try to prevent growth from forming.  This has been done for centuries with many old wooden boats having their bottoms sheathed with sheets of thin copper.
PXL_20210104_132630120Looking nice and straight to me!

Anti-Foul type bottom paint doesn’t last too long, 6 months to 2 years max, before it either wears off or looses all its anti fouling chemicals and you have to haul out, remove all the old and paint on new coats which is neither quick nor inexpensive, to say nothing of the environmental concerns.
PXL_20210104_132658391.MPInstead of “Anti” foul we are going to use international InterSleek 1100SR which is a Foul RELEASE type of solution which in the simplest terms is a coating of silicone fluoropolymer which is akin to the non-stick coating such as Teflon on frying pans.  When I was a young boy I was struck by the idea of “Better Living Through Chemistry” and my daughter Lia is an Organic Chemist so this more modern and much more effective different kind of chemistry that creates Foul Release paint was a no-brainer for me.
PXL_20210104_132600948.MPA little kick up at the stern end of the bottom paint to add a bit of flair!

When moving, nothing sticks to the hull but when we sit at anchor for weeks or months at a time, grown will still form on our InterSleek bottom BUT it all comes off with a simple wipe with a cloth or sponge so the amount of time and effort it will take us to “dive the bottom” and clean the hull will be drastically reduced from our previous boats even though Möbius has a much larger bottom surface.
PXL_20210105_121710267[3]Uğur looked after one more bit of preparation for the bottom painting by sculpting the Exhaust Exit pipe which is not far above the waterline and below the top of the Black Boot Stripe so it too will be painted.

PXL_20210105_121658997I will talk more about the Foul Release and InterSleek1100 paint as we start applying it in the coming weeks, so to finish up for now let me just add that Foul Release type bottom paints and InterSleek are not well known by most boat owners but it has been the norm for large commercial and military ships since the 90’s.  Based on their experience the InterSleek1100 should last for around 5 to 7+  years, so we are eXtremely anxious to see how it performs for us on Möbius.  Stay tuned for the next couple of years to find out! Winking smile

Non-Slip up on Top:

PXL_20210107_073546864.MPJust as important as keeping our bottom Non-Stick to prevent growth, we need to keep all our decks and floors up on top to be very Non-Skid to prevent us from slipping when walking around, often in bare wet feet and a energetically moving boat.

For all our decks and other exterior AL surfaces we are using what we think is the ultimate Non-Slip material called TreadMaster which has the tag line “The Original Anti Slip Deck Covering” which has lasted for more than 20 years for many of our friends. 

In previous weekly updates you’ve seen the Team covering all the Main Decks and stairs with Treadmaster and this week the finished off the last remaining items such as these AL stairs from the Aft Deck down into the Workshop.
PXL_20210107_073556384We will leave all the “Slip Sliding Away” to Simon & Garfunkel while we stay put safe with our feel solidly in place on our TreadMaster and that composite grid flooring down in the Workshop and ER thanks very much!
PXL_20210108_142941793We left what could be the most dangerous or at least slip-prone deck for last; these narrow slopped Side Decks that flank the SkyBridge.  Orkan was able to use all the left over TreadMaster from doing the Main Decks to cut out all these smaller “tiles” of TreadMaster to cover these Side Decks and here he has them all cut out and flipped over upside down ready for the AL Side Decks to be sanded and cleaned.
PXL_20210108_151342777Faruk and Ali could now get busy mixing up the West Systems epoxy adhesive and gluing each piece of TreadMaster into its final positions on the Side Deck surfaces and squeezing out the epoxy to every edge with the HD roller you see here in the foreground.
PXL_20210104_150729359

And in the words of Jean-Louis, Voilà c’est fini!!

TreadMaster is now all done and one more milestone achieved.  Well done Team Möbius!!

Much ADO about Non-Slip Inside Too!

PXL_20201231_064414784Last week you may recall seeing Ramazan finish installing the ADO vinyl LVT flooring in the Master Cabin and he has that now all finished.
PXL_20201231_064536530Keeping ourselves safe at sea requires that ALL our floors are very Non-Slippery and as you can perhaps make out in this photo, we chose these Ado LVT vinyl floor planks in large part due to the highly textured nature they have that is similar to old well worn woodgrain on patio or pool decks.
PXL_20210105_153101626His final job to finish the Master Cabin was the two stairs leading up to the Port/Left side of the bed and the removable access lid beside the Shower.  These are the only vinyl flooring that is glued down, the rest is all “floating” so it can expand and contract in different temperatures.  Here is is using some very heavy weights to keep these pieces flat and squished onto the underlying marine plywood while the adhesive dries overnight.
PXL_20210107_074118757Master Cabin flooring all finished, Ramazan moved onward and upward to the SuperSalon and moved everything off the floors in there and gave all the plywood base a thorough vacuuming and cleanup.
PXL_20210106_105852531First task for the SuperSalon floor was to install the wood framing and rigid insulation on the large hinged hatch that provides access down into the cavernous Basement that lies below the AL floor of the whole SuperSalon.
PXL_20210107_074041873After checking that each plywood floor panel was solidly screwed down, Ramazan stared to do his layout for the floor planks.
PXL_20210107_074157941Starting with this reference line for laying down each row of planks perfectly parallel to the centerline of the boat.
PXL_20210107_113745764.MPClick – Click, assemble one row of planks.

Click – Click, lock that row into the previous one laid down.

Screens, Screens and more Screens!


PXL_20210106_095311058Winding back the clock by a few days, another eXtremely big milestone for Christine and I happened this week and this photo should give plenty of clues as to what this was.

Can you guess what we are up to here?
PXL_20210106_095319924Hint.

It has something to do with these two unfilled spaces front and center at the Main Helm.
PXL_20210106_095328531That’s right!  Time to unbox and install all our beautiful big, sunlight readable, touch screen LiteMax helm monitors; two 19” here in the Main Helm and then two more 24” up on the SkyBridge Helm and then on each side of the Main Helm will be another 43” monitor on the Right and a 50” TV/Monitor on the Left.

After a LOT of research and some help from a fellow passage maker, Peter Hayden over on “Adventures of Tanglewood”  we finally tracked down the OEM manufacturer of most marine MFD’s and monitors and bought all five Helm monitors from LiteMax in New Taipei City, Taiwan. 
PXL_20210106_100430158The two 19” Main Helm monitors are LiteMax NavPixel Marine model NPD1968 and this link will give you all the technical details for those wishing to know more.  The specs that mattered most to us are that these are fully sunlight readable with 1600 nits (a good phone screen is about 300 nits), AOT touch, high shock & vibration resistance, IP65 waterproof and can be powered from 9-36V DC.
PXL_20210106_100538201Both monitors slide into this hinged plate above the Main Helm dashboard and allow us to tilt these monitors however we wish to have the best line of sight and least reflection.  Captain Christine is peeling off the protective plastic layer to check out the non-reflective screens below.
PXL_20210106_100646072Another feature we value highly is that these monitors have physical and easy to reach control knobs and buttons.  Always frustrating to try to figure out how to increase the brightness as daylight arrives and you’ve had the screens turned down close to black for night time viewing.
PXL_20210106_102735742Didn’t take us long to get the two 19” monitors mounted into the Main Helm and so we moved up to the SkyBridge where these two openings on the Upper Helm Station were begging to be filled.
PXL_20210106_111325846.MPFirst we removed the rear AL panel to give us access to the inside so we could tighten down the very well done mounting screw setup on these monitors.

We also put in a layer of thin EPDM foam rubber to fully seal each monitor into the AL Helm Station.
PXL_20210106_104706261.MPThey fit into their openings like a glove and as you can see the big opening we had designed into this AL Helm Station provided easy access all around each monitor to secure them tightly against each frame.
PXL_20210106_104713877These 24” monitors are LiteMax NavPixel model NPD2425 with similar specs as the one’s down below.  Plenty of connection port choices on the back including the power terminals on the far Left which will be connected to our 24V DC system and then via DVI-D to our onboard boat computers.
PXL_20210106_104643455As you might see reflected in the plastic protective covers, I took this shot with my camera at eye height when you are sitting in the SkyBridge Helm Chair so this will give you a good sense of the perspective you’ll have when conning the boat from up here with great visibility of the entire Bow and Anchor Deck up front.
IMG_0974When I wasn’t looking Captain Christine snapped this shot of me finishing up the installation under her watchful eye.

We are eXtremely excited to get these bad boys all powered up and connected to our boat computers but that will have to wait until next week so stay tuned for that.

POWER!

PXL_20210105_070759362Speaking of powering things up, whenever Mr. Gee is running we have up to 24kW of power from the two Electrodyne 250A @28V alternators he is spinning down in the Engine Room.  Here is a peek at the cabling that Hilmi completed this week which takes the AC output from the stator windings directly to the externally mounted Electrodyne Rectifiers over on the far Right side of the Workshop.
PXL_20210105_140040082.MPEach of these Electrodyne beautiful brutes has two individual alternators inside and so there are six cables coming out of each alternator to carry the 3 phase AC current.  So Hilmi  put his hydraulic lug press to good use crimping all 12 lugs onto each cable.
PXL_20210105_141320446That shot up above is of Big Red #2 which is driven by the PTO off the bottom Left of Mr. Gee which you can see a wee bit of in the very bottom Right of this photo.

On the Upper Left here, this is Big Red #1 which is mounted up above on this 40mm/ 1 5/8” AL plate I fabricated and bolted onto the pad on Mr. Gee’s cast aluminium crankcase just for this purpose.  This will be driven by a cogged “timing belt” setup which I am busy fabricating right now and I will show you more of next week.

Here though you can see the other six cables coming out of the Junction Box atop Big Red #1 on their way over and out of the ER to connect to the Rectifiers that are staying nice and cool out in the Workshop.

Mr. Gee Gets Cagey

Those with eXtremely sharp eyes and memory might notice a new addition to Mr. Gee this week?


Mr. Gee cage   exhaust support modelKeeping with our KISS or Keep It Simple Safe & Smart approach, I designed a dual purpose AL pipe “cage” to wrap around Mr. Gee to provide solid hand holds whenever you are near him while he’s running.  This then also creates the perfect base for the four support rods that go from the pipes of this cage up to the exhaust dry stack system up above which I will show you more of next week.

PXL_20210104_080045592I pulled off the 2D drawings from my Fusion 360 3D mode above, sent them over to Uğur on WhatsApp and he and Nihat got busy transforming these 2D drawings into 40mm AL pipe reality down on the shop floor.
PXL_20210104_080051729Same technique you’ve seen us use before, Uğur and Nihat create these large radius bends by cutting a series of slots on the inside of the curve in the 40mm thick wall AL pipe, bends them and then tacks them in place.
PXL_20210104_111702902.MPWe then test fit them in place on Mr. Gee and once tweaked into just the right fit Uğur welds the slots closed.
PXL_20210104_111706646As you might notice on the model rendering above, each “staple” shaped rail will be bolted to AL plates that span the motor mounts we fabricated here at Naval.
PXL_20210104_132736071.MP

Uğur could now weld on the 20mm / 3/4” thick base plates and weld all the bend slots closed.
PXL_20210105_064707202Nihat picks up with his angle grinder and quickly cleans up all the welds to create smooth soft curves.
PXL_20210105_132358340That gives Uğur time to go back into the ER and drill and tap all the threaded holes in the Engine Mount plates so the finished staples can be bolted in place.

Uğur and Nihat were only available Monday and Tuesday this week so this is where they left off and will pick up again tomorrow (Monday) morning to bolt in the longitudinal pipes and start fabricating the support rods that attach to the four AL tabs you can see they have now welded to the tops of each stable rails and will connect to the SS dry stack exhaust pipes you can see here.

We’ve Been Hosed!

PXL_20210104_081956996.MPOur eXtremely productive plumber Cihan was also with us for Monday and Tuesday and he made great progress plumbing in a lot of hoses and other items so let’s check that out.
PXL_20210104_081940739This is outside the Aft Stbd/Right corner of the Engine Room Enclosure with the plate removed that covers the far end where the prop shaft enters the ER and connects to the Nogva CPP Servo Reduction Gearbox via the Blue (purple looking here) dripless Tides Marine shaft seal. 
PXL_20210104_081947563.MPUp above and off to the far Right side of the prop shaft, you can just see the silver coloured AL heat exchanger with the bronze elbow which is what Cihan is now plumbing with this white hose.

This is the heat exchanger that cools down the fresh water/antifreeze mix that circulates through the inside of Mr. Gee and that is what this white hose carries to/from Mr. Gee and the heat exchanger.

If you look at the black composite end plate on this heat exchanger you can see that Cihan has already connected the hose that carries the cool sea water from the Sea Chest in the ER.
PXL_20210104_082003577Inside the ER on the Right side of Mr. Gee you can now see where two of the white sea hoses connect to Mr. Gee.  The top hose in this photo will carry fresh water coolant from the integrated water pump on Mr. Gee and the bottom hose carries sea water out of the long Bronze Engine Oil Heat Exchanger back to the Coolant Heat exchanger we saw in the  photos above.
PXL_20210105_131800135My apologies for not having time to draw up some better illustrations to explain how these heat exchangers all interconnect but for now this photo will show you two of the pumps in this system.  The round aluminium pump in the center of the photo above is the integral Garner centrifugal water pump which pumps fresh water/antifreeze coolant back from that silver AL heat exchanger we saw earlier.


PXL_20210105_131741168 The Bronze Jabsco pump on the Right is one that I am in the process of mounting and it is the impeller pump that pulls sea water from the ER Supply Sea Chest into the “IN” labelled port and then out of this pump into that bronze elbow with the Blue painters tape up above.  This sea water then runs the length of that Bronze Engine Oil Heat Exchanger bolted to the side of Mr. Gee and exits via the white hose you can see two photos up from here and goes down to that silver AL heat exchanger we saw at the beginning. 

The longer white hose in this photo carries Mr. Gee’s fresh coolant back to that silver AL Heat Exchanger.

Clear as mud to most of you and a pathetic job by this former mechanics teacher but best I can do for now folks.
PXL_20210105_071052003The other new addition this past week was Cihan’s installation of this Blue Beauty which is the big “sand” filter which removes most of the sea critters and debris from the salt water supply for the Delfin 200L/min watermaker.

This is not found in most boats and are normally used in large swimming pool installations, but I long ago discovered that these are the “secret” to extending the life of the other two sea water filters on the watermaker last for months rather than weeks.  This filter is filled with a special kind of sand known as Zeolite and it is the first line of defense to filter out the sea water being pumped out of the Sea Chest into the watermaker.
PXL_20210105_071100105There is a six way valve on top which you use to change between running the seat water through the filter and back flushing it in reverse once in a while to fully clean out all the debris that has been collected by the Zeolite sand.  Simple, easy and eXtremely effective.
PXL_20210105_071146113Super simple in design and to use and plumb with just three ports:  Top Right SS hose barb is where sea water is pumped into the filter by the low pressure high volume 24V pump connected to the Sea Chest.  Bottom Right is where the cleaned sea water exits and is pumped over to the two standard filters behind the watermaker.  Far Left with the SS elbow is where the dirty back flushed water exits and goes out the exiting sea chest in the ER.
PXL_20210105_144625975In the background on the wall behind the white watermaker housing on the bottom Right, you can see the three other WM filters; the pair on the Left are the Primary/Secondary sea water filters and the one off to the Right is a carbon filter to remove any harmful chemicals in the fresh water you use for back flushing the WM at the end of a run.
As usual of late I’ve got more photos to show you than I have time and dinner is once again waiting with my eXtremely patient and beautiful Bride on this Sunday evening so I’m going to call this a wrap for now and do my best to cover more next week.

Thanks for joining me on this first posting of 2021 and I hope it helps in some small way to get your new year off to a good start.  How about if YOU start your New Year off by adding your comments and questions in the “Join the Discussion” box below?  They are all true gifts to me and much appreciated!

See you next week.

Bye Bye 2020; Hello 2021 We are clearly floored! XPM78-01 Möbius Progress Update Dec. 28-31, 2020

Though I continue to shake my head in disbelief,  it does indeed appear (on Jan 2nd as I write this)  that this tumultuous and challenging year that was 2020 is rapidly ending and 2021 just as rapidly beginning. Actually, it is now Jan 2nd as I am writing this so as usual, Wayne is way behind!

As with many of you I suspect, seeing the end of 2020 is somewhat welcome as we look to put most of the severely challenging aspects we experienced in 2020 behind us.  However being the “terminal optimist” I am, my observation would be that the end of 2020 is all the more welcomed with exponentially increasing trend lines of positive progress that is happening around us as 2020 winds down.  This progress is both in the most important and macro view of the truly awemazing progress that has been made with more and more effective vaccines and testing for Covid-19 as well as in my much more micro perspective of finishing and launching XPM78-01 Möbius.  I think most of you might agree that ending the year with positive progress rapidly rising is certainly a welcome change from when it was all going the other direction,

One of the words I would personally chose to describe 2020 is “accelerant”.  My brilliant and beautiful daughter Lia is a very successful chemist and one of the many things I learned through her is that, as Wikipedia words it

Accelerants are substances that can bond, mix or disturb another substance and cause an increase in the speed of a natural, or artificial chemical process. Accelerants play a major role in chemistry—most chemical reactions can be hastened with an accelerant.

My point here being that I think that as we put 2020 in the rear view mirror and perhaps provides us with the 20/20 or better “vision” that hindsight most often does, we will see that 2020 was very much an accelerant for trends that were already happening prior to the beginning of 2020 and increased the speed and rate of change of these trends which were BOTH, positive and negative.While making sure to attention to and learn from those negative trends  I chose to focus on the positive trends which have been equally or great accelerated by the events of 2020 and which I will try to further in 2021 and beyond. 

Very selfishly, those trends include the accelerated rate at which Christine and I hope to finish the building of Möbius and start a whole new trend which we can also accelerate, that of returning to our life at sea as full time liveaboards as we pick up where we left of in “wandering, pondering and wondering the world one nautical smile at a time.”  You can be the judge of how well we do at this if you chose to continue to follow our adventures here on the Möbius.World blog as we make the transition from building to cruising.  Wish us luck, we’re going to need it!

OK, after yet another “brevity challenged” opening, let’s get to what you really came here for;  this week’s Progress Update Show & Tell for the 3.5 day week of December 28-31, 2020.  New Years is a VERY big deal here in Turkey and so everyone on Team Möbius and Naval Yachts was very anxious to finish up at 13:00 on Thursday and get the New Years festivities started.  It all worked out very well on the calendar as well as this gave all of us a 3.5 day weekend to celebrate the end of 2020 and ring in 2021.  As in many parts of the world there was no shortage of fireworks for Christine and I to enjoy from our 9th story apartment here in Antalya as we toasted this dual closing and opening of windows in our world.  We hope that however and wherever you were for New Year’s Eve 2020 that you too were able to celebrate this annual transition and that 2021 will turn out to be one of if not the best year we have ever had.

Why is Wayne Floored?

PXL_20201230_064314702Two very good reasons this last week of 2020 has me so floored and this is the first; Uğur and Nihat installed the grated floors in the Engine Room surrounding Mr. Gee!  This is the same very cool composite floor grating that you’ve seen us installing for the floors in the Forepeak and the Workshop.  eXtremely rigid, impervious to all chemicals, easy see-through to the bilge spaces below, easy to install and lift out when needed.
PXL_20201228_152119866Very simple aluminium L-bar framing to support these floor grates which Nihat and Uğur have perfected now and weld up in a jiffy.  This is the frame for the raised floor at the Aft end of the ER.
PXL_20201228_092247916.MPBy raising the floor here about  200mm/8” above the two side level floors flanking Mr. Gee, we were able to make this all one level floor across the whole width of the ER.
PXL_20201228_141405395In addition to the Safety factor when moving about in the ER during our hourly ER checks on passages and when I’m working in there, the grating also protects the hoses, solenoids, dipstick, etc. on the Nogva CPP Servo Gearbox and the two heat exchangers on either side of it.
PXL_20201230_063915903Then we dropped the two side floors down to be about 50mm/2” above the tank tops so as to give me the maximum amount of space on either side of Mr. Gee when I’m servicing and working on him.  This Port/Left side is the service side of the Gardner 6LXB where the majority of components are such as the fuel injection system, dipstick, on engine fuel & oil filters, throttle lever, etc. so it is wider and longer and relatively clear of other obstructions other than the sea water exit manifold that connects to the exiting Sea Chest in the top Left corner.
PXL_20201230_063920585.MPPurposely a bit busier on the opposite Starboard/Right side where the dual sea water intake strainers and the sea water supply manifold live and connect to the Supply Sea Chest partially visible in the upper Right corner here behind the 127mm/5” ID exhaust hose as it exits the ER and runs under the Day Tank to exit out the side of the hull.

The red hose is now ready for Cihan to install on the side of Mr. Gee where it will transport the engine coolant (water + antifreeze) out of the ER and through a heat exchanger loop inside the Webasto IsoTherm Calorifier/water heater tank where it gives up some of its heat to our DHW Domestic Hot Water system and reduces the need for the Kabola KB45 diesel boiler to provide our DHW whenever Mr. Gee is running.
PXL_20201230_063859528.MPI am very happy with the way this has all turned out and how much it adds to our priorities of Safety, Comfort and Low Maintenance inside the ER.  In the next week or so Uğur and Nihat will be fabricating and installing the Exhaust System supports which will add even more safety to working in here and I’m already excited about showing you that.

Master Cabin is Floored!

And what is the second reason I ended the year being so floored?

PXL_20201228_084920099.PORTRAITHmmm, it sure doesn’t look that it has to do with increasing the comfort of the big bed in the Master Cabin?


PXL_20201228_084916783.PORTRAITOh wait!  This is where Ramazan has put all the planks of LVT vinyl flooring for the past 2 days so that little ceramic heater in the upper right corner can bring the temperature of everything up 20+ degrees C / 68F where Ado, the manufacturer, recommends for installation.
PXL_20201228_141559667These LVT planks are installed as a “floating floor” so no adhesive is used so that the vinyl can expand and contract a bit without causing any buckling or warping.  As we will be taking Möbius through the full spectrum of temperatures from the poles of Antarctica and the Arctic down to the tropical heat on the Equator, we need to account for these kinds of conditions.


PXL_20201231_064552368Each plank “click locks” to the next plank on both sides and ends so the installation is relatively easy but quite time consuming on a boat where there are almost no square corners or parallel lines and so all the planks at the ends and sides of each room must all be carefully and accurately custom cut and fit.

Here is a good example of that where Ramazan had to carefully cut the LVT flooring to fit just right around this area just inside the door on the full height wardrobe as you enter the Master Cabin.
PXL_20201228_141607446Ramazan started by laying out the Centerline of the hull and using that to provide the lengthwise reference line for laying down all the LVT planks.  Then he worked from there putting down the LVT planks parallel to this Centerline and cutting the edges to fit just right up against the Rosewood wall panels.
PXL_20201230_064146447The blank plywood rectangle under the vacuum is one of the many places on the Master and Guest Cabin floors that need to be removable to allow you to get at the access ports to the water and fuel tanks below all the floors.  This one in the Master Cabin is the largest of all because it spans the corners of four individual water tanks which we located here for that reason.
PXL_20201231_064414784Hey!  I would have sworn that there used to be a removable access panel here?!?

Ramazan is quite the flooring expert having apparently laid down a lot of this LVT flooring and you can see this on display here where he has been able to make the joint where the ends of the LVT blanks butt together with almost no gap at all.


Double lifting suction cup toolOn the rare occasions when we need to remove these sections of the floor to inspect or clean out a fuel or water tank, we simply use one of my favorite tools, an industrial suction cup like this which you’ve seen us using to install the big 26mm thick laminated glass panels round the Pilot House a few weeks ago.
PYI Floor Anchor DetailsWe won’t get to installing these until a bit later but in anticipation of the inevitable questions about what happens to these removable floor panels in the unlikely event of a full roll over (lets hope!), we will be installing these SS floor anchors.  I’ve used these floor anchors from PYI before on previous boats and they not only work eXtremely well, they are more bits of kit on my “boat jewelry” list for being so beautifully designed and built.
PXL_20201231_064501056Flooring pretty much all done in the Master Cabin and here is a full length shot of the floor alongside the bed leading to the stairs up to the SuperSalon.

We are eXtremely pleased with how all the various colours, materials and textures have all come together.  Not bad for two very inexperienced interior designers don’t you think?

And the indirect dimmable LED string lighting really helps to not only increase the Safety factor throughout but also really uses the Silver/White colour we chose for these LVT planks to maximum advantage in reflecting and diffusing that light across the floors and around the edges.
PXL_20201231_064511045What better way to show you the flooring than by getting down on floor level?  Best I could do to try and show you the texture of these LVT planks which works eXtremely well as a non-skid surface even with bare wet feet.

BTW, the LED strip lights are just being test fit right now and will soon be installed into their grooves with some clear silicone to keep them fully hidden and well secured.

Fitting out Mr. Gee

PXL_20201231_092009785Cihan was able to return for two days this past week and he is always a treat for me to work with and is super productive.  Remember those red hoses that connect Mr. Gee’s hot water to the Calorifier you saw in the ER in the Flooring section above?  Cihan now has them all connected and starting to insulate them to keep the heat in the water and out of the ER.
PXL_20201231_091908765This is the front Stbd/Right side of Mr. Gee and we are tapping into his AL coolant manifold up on top of the cylinder head to return the coolant from the Calorifier.
PXL_20201231_091959338We then tapped into what was a drain plug fitting in this lower coolant manifold where the water comes out of Mr. Gee’s side mounted centrifugal water pump.
PXL_20201231_093903582Over on the opposite Port/Left front corner of Mr. Gee, Cihan now has the diesel fuel return line hose connected now.
PXL_20201222_152215524With Cihan being so busy on other jobs at Naval I’ve been busy lending a hand by fabricating some of the mounts he needs to complete jobs such as mounting one of the big Electrodyne 24V 250A  alternators on that same upper left corner of Mr. Gee you see in the photo above.


PXL_20201222_152230392KISS right?  Some 20mm/ 3/4” thick AL plate gives the neccessary strength and rigidity to support this hefty alternators that tip the scales at 33kg/73lbs each.  Ask me how I know?!
PXL_20201222_104857883Once I had the two plates all drilled for the four mounting studs on Mr. Gee and had worked out the precise location of the alternator so that its serpentine belt pulley would be aligned and on the same plane as the other three pulleys I could drill and tap this 40mm/1.6” thick mounting block.
PXL_20201230_113719726After test fitting this on the Electrodyne alternator the mounting block needed a bit of trimming to fully clear the body of the alternator when bolted in place but nothing that my super handy Milwaukee angle grinder could make short work of.
PXL_20201222_153045213Here is the final result with Big Red #1 now fully fitted onto Mr. Gee. 

I’ve lost track of how many times I had to lift all 33kg of this beautiful red beast up and down to get these mounts all worked out but I’m thankful for the workout that helps me keep my girlish figure I guess! Smile

Also pleased with the way this mount will work out position wise to give me good access for future maintenance and with being rock solid to carry on the Gardner tradition that Mr. Gee demands.
PXL_20201222_153052827[4]For those wondering, the six terminal studs on the sides of the junction boxes on each Electrodyne are where the AC current comes out of the two “Siamese twin” alternators inside each Electrodyne and then carry that 3 phase AC current over to the external Rectifiers mounted outside the ER over on the Stbd/Right side of the Workshop. 
PXL_20201222_153026382That AC current will be carried by those 12 Red cables, 6 from each Electrodyne, that you can see coiled up to the Right of the alternator and in some of the photos in the ER Flooring section above. 

Next up for me is to work on getting all the cogged belt pulleys mounted and aligned but that will have to wait till next week.

I Can See CLEARLY NOW!

PXL_20201125_143726657.MPSaving the “Clearly” part of this week’s title for this last part of our Show & Tell this week as this is another one of those big milestone events in the build for Christine and me.  It actually all started more than a month ago when this photo was taken.  Do you see the clues as to what this is all about?
PXL_20201125_143924192.MPDoes this closeup help you guess?
PXL_20201125_120008079.MPCorrect!  This was when the acrylic team from Hakan Glass was onboard back in November to build the hardboard templates for each of the 15 removable acrylic windows that will allow us to make the whole SkyBridge weatherproof!
PXL_20201129_115124003Let me backup a bit and show you the design that I worked out with the guys at Hakan Glass.  This test sample they made will help me show you how it all works. 

Four basic components …………………… 
PXL_20201129_1152268231.  The clear 8mm / 3/8” thick cast acrylic sheet that forms the tough windows.  Cast acrylic is more heat and scratch resistant than common Plexiglass which is usually extruded.  Acrylic has a tensile strength >10,000 lbs/sq inch and an impact resistance about 17 times greater than ordinary glass and under high impact, (cyclones anyone?)  it won’t shatter and if it does break it fractures into large, dull-edged pieces.

Acrylic is also eXtremely clear, half the weight of glass and resistant to most chemicals.

Clear, Safe, weatherproof, not easily scratched.

Low Maintenance – Check image
PXL_20201129_1152092642.  Aluminium anodized U-channel extrusions for the track frames that hold the acrylic sheets in place.  Note that the U-channel on the Left has its upper side cut down to be half as high as the regular one on the Right as that is key to how this system works as I’ll explain in a minute.

Being anodized AL these U-channel extrusions are easy to keep clean and never oxidise.

 PXL_20201223_1055357053.  Black EPDM rubber edge molding that keeps the sheets tightly in their frames so they don’t rattle or move.

PXL_20201129_1154504784.  To add some Secret Sauce to the mix let’s stir in two strips of these silicone magnetic seals that are typically used on glass shower doors.

Simple to use, Clear, Long lasting & Weathertight.

imageComfort + Low Maintenance – Check


PXL_20201129_115332914Now let’s put it all together to see the solution we’ve cooked up for Möbius’ SkyBridge.

Remember how we cut off half of the height of one side of the lower U-channel? That’s what you are seeing here.  With half the height of the inside wall of the bottom U-channel, you can push the acrylic sheet all the way up into the full sized upper U-channel which allows you to now push the bottom edge of the acrylic panel into the U-channel and then push it down and presto, you’re done!
My inspiration for this design comes from something most of you would likely know from putting bug screens in and out of the outside windows in your home.  You know the ones where you remove them by pushing the frame of the bug screen up into the top U-channel in the window frame and then pull the bottom out of the lower U-channel which it now clears. 

There is always great elegance to me in simplicity.


PXL_20201129_115614198PXL_20201129_115615688But what about where two acrylic sheets need to butt together on the long side stretches of the SkyBridge you ask? 

Aha!  Simple, just press a length of these silicone shower door strips onto each edge and their internal magnets snap the gap shut.
PXL_20201223_080352298Last step, with each acrylic panel installed just press the Black EPDM rubber edge molding firmly into the small space between the inside edge of the AL U-channel to lock the acrylic tightly in place.

PXL_20201129_115749566et voilà! 


PXL_20201225_092829292.MPYou’ve can now clearly see those beautiful views all around you from this premium vantage point high above the water while all the wind and rain stay outside and you are completely dry and comfy inside.
Wait …………………. What’s that you say?  You are now in the tropics and it is hot and humid?  You want those high up beautiful views more than ever but you also want some good breezes and fresh air? 

No problem.  Möbius has you covered.  Just lift out as many of those acrylic window panels as you’d like because every one of them is removable!
Double lifting suction cup tool  But how would you remove them you ask?

Ahhh, remember out little friend from the previous section on how we lift out the removable floor panels?  Yup, that same little fella works even better to grab onto those sleek smooth acrylic panels and quick lift up and out comes the panel to be stowed away while all those fresh tropical breezes flow through and keep you cool and smiling.

Well, you get the idea.


OK, now let me quickly flash through what the process looked as the talented boys from Hakan Glass cooked up this recipe of 4 simple ingredients I had put together:

PXL_20201113_122015789Start by cutting some of these 3m/10’ lengths of anodized AL U-channel in a table saw to take off 1/2 the height of the one edge for the bottom and some of the side frames.
PXL_20201123_071104967Glue the U-channel pieces to the tops and bottoms of the AL framed openings of the SkyBridge and its roof using clear industrial epoxy adhesive.
PXL_20201124_142542680.MPOnce all the lengths of U-channel have been affixed, tape off the joints where the U-Chanel joins with the frames of the SkyBridge on the inside and outside ….
PXL_20201124_142624795 ……. then apply a small cove of black Sikaflex 296 to completely seal these joints and add a nice visual accent to these edges.
PXL_20201125_115922255.MPCut and fit hardboard to create templates for each removable acrylic window panel.
PXL_20201125_115931904Cut and fit the two magnetic edge seals where two acrylic window panels meet to make sure that the size of the templates are just right when they are pushed Up/Down into place and the two aft corner panels are also pushed sideways into their vertical U-channels.
PXL_20201125_143934495.MPRinse and Repeat for all 15 window panels surrounding the SkyBridge and then take the templates back to the Hakan workshop to cut them all to size.
PXL_20201221_141347712Two weeks later, make Wayne’s day by bringing all 15 acrylic window panels to him on Möbius.
PXL_20201223_080125135.MPClean up all the edges of the acrylic panels and start fitting each numbered panel to its awaiting U-channel frames.
PXL_20201223_080139193Finish off the Black Sikaflex sealant and remove all the Blue painters tape.
PXL_20201223_080405387Let Wayne double check that the EPDM seals squeeze each acrylic window panel to his just right Goldilocks fit to help them seal and be rattle proof.

Sheesh!  Some Owners are SO fussy!
PXL_20201223_080552036Peel off all the protective plastic covering on the outside and ….
PXL_20201223_080632921 ……. inside of each acrylic panel.

Note the 10 year guarantee!
PXL_20201223_105201917.MPClean up the Sikaflex seals on the inside and clean off all the aluminium with solvent.
PXL_20201223_105351841Let Mr. Fussy get his kicks by checking out how slickly and strongly these magnetic strips old the vertical edge joints together and get tighter as the wind pushes against them.
PXL_20201223_105929636Sides and Aft end panels all in place now with their magnetic seals and Black edge trim.
PXL_20201223_110802698.MPFinish putting in the Black EPDM strips on the three front facing windows.
PXL_20201225_092829292.MPStand back and take a tour around the boat to admire this outstanding job!
PXL_20201225_103154314Crystal clear view out the Aft facing windows from the outside and …..
PXL_20201225_103245634 …… the inside.
PXL_20201225_103230551And all clear from the Upper Helm Captain!
PXL_20201223_083739660.MPAnd looks eXtremely sharp from the outside too!

Well done Hakan Glass!  Gold stars to you all with our thanks for such clearly outstanding work!
And that’s a wrap for the week, the month and the year that was 2020!

Happy New Year to one and all and we can’t wait to bring you the final episodes as all of us on Team Möbius renew our efforts to finish off Project Goldilocks and put this awemazing boat, and her Owners where they belong; IN THE WATER!!!

See you again next week as we get 2021 off to a rapid start!

What if Beauty & the Beast had a Love Child? XPM78-01 Möbius Progress Update 07-12, 2020

With Team Möbius back to work and augmented by additional sub-contractors the rate of progress was at an all time high this past week so there is a LOT to Show & Tell you about this week.  I will apologise in advance that this week’s Progress Update may be a bit rushed both because I have so much to cover and it is now already mid afternoon on Sunday here.  But before I jump right into all the progress updates, some other news from around the shipyard for you.

FINAL PLANS are SIGNED & SEALED!

Baris & Dincer signing Addendum v2-5The biggest news for Christine and I this week is that we finalized all the details for the final finishing of XPM78-01 Möbius with Naval Yachts and signed off on all the new addendum documents, which is what Baris (left) and Dincer, the founding brothers of Naval Yachts are smiling about here! 
With projects of this size and complexity and especially for such a unique first XPM series build, there are a LOT of changes and adjustments along the way and a LOT of equipment, materials and sub-contractors that needed to be ordered and it has taken all of us more hours than we would like to know, to sort out all these details and get them all formally documented.  So we were elated to have all four of us, Builders + Owners, sign off on this Friday afternoon.

Wayne Looses 1 old Titanium Screw and Gains 7 new ones!

Immediately after we all signed the new addendum on Friday, my elation transformed into something else when I spent several hours “under the knife” in the Dentist’s office!  Another reason why this blog post will be a bit rushed as I’m not quite up to full  speed again just yet. 
For those curious to know, the scorecard from that surgery is that Wayne is now:

MINUS:

  • one molar and
  • one titanium screw (one of more than a hundred I have from a nasty motorcycle accident back in 1997) but now plus 6 titanium implant

PLUS:

  • 7 titanium implant screws
  • some extra jawbone (grafts)
  • 29 stitches

dental-implants-massachusetts-nhI won’t bore you with any more details but given the somewhat technical nature of my posts and for those curious about dental implants, as I was, here is these 2 illustrations will give you the basic picture of what’s involved.

implant2Now it is just a waiting game to get the stitches removed in 10 days and then let the jawbone and implants merge for two months or so before I go back to have the ceramic (Zirconia) crowns put in and I can chew again!

Möbius gets a New Neighbor

PXL_20201202_073019553.MP

This actually happened two weeks ago so I’m a bit delinquent in posting this but we now have a new neighbor off of Möbius’ Stbd Aft corner. 
PXL_20201202_070022961.MPShe’s a Turkish flagged boat “Celeb” and is in the yard at Naval Yachts for some relatively minor work and some out-of-the-water winter storage.
PXL_20201202_073028119Once again, our friendly neighborhood 72 wheel Yellow boat mover was called in for this move and it all came off without a hitch as usual.
PXL_20201207_063306545There were more changes to the neighborhood a few blocks away from us over on the Free Zone side of the harbour where they are completely redoing the shoreside facilities to put in an all new humungous dry dock and other launching facilities.
PXL_20201207_063311854This work has been going on for quite a few months already with the removal of the existing concrete walls, the whole rail launch and TraveLift launch facilities and a whole lot of dirt to enlarge the water area.

That leaves the Free Zone with no launching facilities but fortunately just on the other side of this harbor in the background here, is Setur Marina and so the authorities can open up the gates and let the boat movers bring boats in/out of the marina and into the Free Zone. 

With Möbius’ launch date *hopefully* coming up early in the New Year it is likely that we may need to launch into Setur Marina rather than inside the Free Zone harbour.  Either way works fine as the emphasis for us is LAUNCH ASAP!!


PXL_20201207_063309337This pile driver has been running non-stop 24/7 for the past week putting in over 20 so far of these steel cylinders which I presume will be filled with concrete to form the underlying foundation for all the new concrete and dry-dock equipment to come.
OK, with this week’s episode of  “What’s New in the Neighborhood”, let’s get back to the shipyard and get you caught up on this past week’s progress on finishing XPM78-01 Möbius.

LITTLE JOBS = BIG DEAL:

As I did in last week’s posting, let me quickly run you through a set of several “little jobs” which got looked after this past week.  Some of you sent in comments noting that you liked the more rapid-fire sequences of work so I will repeat that here and please do let me know how well it is working or not by putting your comments in the “Join the Discussion” box at the bottom of every blog posting.

And as I noted last week these may be “little” in terms of amount of work, these jobs are all play very important roles themselves and perhaps most important of all are what define a FINISHED yacht!

PXL_20201207_065803494First good example of how these little jobs can be so important was the finishing of the door into the Engine Room.  Uğur and Nihat had fabricated and mounted this door many months ago but it needed to be fully insulated with fireproof EPDM insulation covered with the laminated aluminium/composite sandwich AlucoBond material you have seen being used to cover all the walls and ceilings of the Engine Room and Workshop.

They started by welding in these short lengths of aluminium L-bars for the AlucoBond to be fastened to.
PXL_20201207_074407324Then Nihat cut the 50mm / 2” thick EPDM foam insulation and fitted each piece into their compartments.
PXL_20201207_091641911.MPAlucoBond is then cut to size and screwed in place.
PXL_20201207_091651554.MPUğur than installs two of the same beautiful Bofor Dogs & Latches you saw him installing in the big AL hatches up on the main deck for the Forepeak and Engine Room.
PXL_20201208_075045601Then the door can be remounted on its hinges while it awaits the 26mm thick tempered glass window to be installed to complete this door.
PXL_20201208_082758414Next up for the same basic treatment was this hatch that goes into the floor in the SuperSalon to provide the only access to the cavernous Basement which sits under the entire SuperSalon floor.
PXL_20201208_085739733.MPSame 50mm EPDM foam is inserted into each of the little bays formed by the reinforcing AL stringers of this hatch, which is upside down here BTW.

Then Uğur spreads on a light coating of contact cement while ……….
PXL_20201208_085748314.MP……. Nihat cuts out the thick foil covered fireproof cloth that will cover and protect the EPDM insulation.
PXL_20201208_105411719With the foil cloth all glued down, Nihat finished off the edges with some AL foil tape and this hatch was then mounted to the awaiting piano hinge in the Salon floor opening into the Basement.
PXL_20201210_091317725The first of many “little” jobs in getting the below the waterline portion of the hull all prepped for the upcoming application of all the epoxy primer preceding spraying on the International InterSleek 1100SR Foul Release bottom paint we have decided to use.

Here Uğur has removed the propeller blades on the Vetus Bow Thruster and sanded all the internal AL surfaces.
PXL_20201208_094130489I was able to pull my weight a little bit this week as well by finishing off some similarly small but important jobs, as well as one quite BIG BEAUTIFUL BEASTLY job on Mr. Gee, our Gardner 6LXB engine.  More on that later.

The Black cone and disk up near the top Left here is the front end of the Chain based Hand Cranking system that I am now starting to mount.  I have pulled it far forward here in order to mount the cast AL coolant tank.

Below this tank on the Right is the secondary fuel filter and return line and in the weeks ahead you will be seeing much more of that flat rectangular Pad in the bottom Left where I will soon be mounting one of the Big Red Electrodyne alternators.
PXL_20201208_094136808A classic example of how Gardner leaves nothing to chance is this cast in place detail of how you need to use the correct type of anti-freeze and fill it to the correct level.
PXL_20201210_143328346Big Red #2 near the bottom Left with blue taped box, as I’ve taken to calling the second 250A @ 28V Electrodyne alternators is the much bigger job I worked on this past week and I’ll cover that in more detail a bit later in this post.  With this 2nd alternator now securely mounted to the side of Mr. Gee I was able to finish installing these beautiful copper oil lines that snake their way around Mr. Gee to carry his lifeblood engine oil to and from where it needs to go.


PXL_20201210_143324987Large AL unit taking up the center of of the photo above and aft end here, is the complete fuel pump and mechanical injection system.  The six vertical (5 Black 1 Red) levers you see in the photo above allow you to hand prime each of the 6 fuel injectors as well as shut off one injector at a time to check performance while running.

Burgundy cylinder in the top middle is the secondary oil filter housing with its copper oil lines bringing oil to/from this filter.
PXL_20201210_143238782A few more finishing touches on Mr. Gee’s Stbd/Right side such as the exiting salt water hose now connected to the rear of this gorgeous cast bronze engine oil cooler, and the vertical braided SS mesh exhaust connector in the upper Left here is now bolted to the aft end of the cast iron exhaust manifold.
PXL_20201210_143154653In the bottom middle of the photo above and up close here, the Black 24V Starter is now fully installed and connected.  Two Red cables as one is from the twin FireFly G31 starter batteries and the other cable can connect the starter to the massive House Battery Bank in case the starter batteries should ever not be working.

Beauty & the Beast’s Love Child?

Gardner 6LXB CLOSEUP alternator strap mount exploded diagram

Take note in the 2 photos above of how Gardner attaches the starter to the massive cast aluminium crankcase with that silver strap and you can see in this illustration from the 6LXB Parts Manual how they attached the standard Gardner alternator in the same way over on the opposite side.

PXL_20201130_091059790I wanted to mount Big Red #2, which is what I’ve come to call the second Electrodyne alternator, to the same place that Gardner used but would Big Red fit?  Only one way to find out; try it!  As did Gardner, I first made 2 shims from some AL 10mm plate to adjust the radius of the cast in place ribs to match Big Red’s 188mm / 7.4” outside diameter and bolted them in place as you can see here.
PXL_20201130_091053884Here is an uncluttered straight on shot of the mounting base for Big Red #2.  Fuel pump bowl in the upper Left corner, bottom of the cast AL injection pump running across the top and you can see the two “nubbins” where the hinge pin will slide through to hold the forked bolt that tightens the flat strap to cinch the alternator up tight.
PXL_20201127_132125627That forked bolt is part # 11/19/20 in the illustration above but with Big Red being a bit on the Beastly side of the girth scale the original forked bolt was too short so I whipped up this new larger and longer version out of some SS plate and threaded rod.
PXL_20201127_134248126.MPI fashioned the fork out of a small block of SS and tapped it for a M10 threaded rod and threaded the two together.  A SS nut to lock it in place and then for added safety and strength I thought it best to TIG weld the nut and threaded rod to the fork.
PXL_20201123_121423664I will give you that I can be given to some hyperbole and eXaggeration from time to time but I think you need to give me that it is no eXaggeration to suggest that “shoehorn fit” describes this situation?!!
PXL_20201123_121407320Each GE 250-24 Electrodyne alternator tips the scales at 40 kg/88 lbs and so again I will make my case that calling these Red Beauties Beasts is also no mere Hodgins Hyperbole!
PXL_20201125_125418339As you might imagine, I had to take Big Red #2 in and out quite a few times as I adjusted its position and tested out the strap mounting setup to get that all to work out and still  clear everything.  Fortunately and as I’ll explain in a bit, took advantage of the fact that I had to take these alternators apart so I was able to cut their weight down quite a bit which made all my test mounting a bit less muscle building.
PXL_20201130_090928226With the alternator temporarily held in place with some wood blocks I could test out the fit of this Black strap which is has a 10mm / 3/8” pin that slides through the bottom as you can see in the illustration above and the bottom of this photo. 

Up at the top you can see the nut on the end of the upper forked bolt what cinches the alternator tight up against the radiused ribs you saw earlier.

I am close here BUT the large copper wires that carry the AC current out of the alternator need to come through that hole in the case across from my fingers, so I need to nudge it forward a wee bit more so the strap clears the hole.
PXL_20201123_121426909Oh, and I also need to make sure that the length of this Jack Shaft with U-joints on each end that I am retrofitting to drive Big Red #2 from the Gardner PTO (Power Take Off) on the Left here.

(click to enlarge any photo)

Electrodyne E 250-24 specs   graphI’m getting ahead of myself a bit so let me stop and provide a quick overview of these Electrodyne E 250-24 alternators that I’ve chosen to use and mount on Mr. Gee which I think will help you see how they truly are the Goldilocks combination or “Love Child” of Beauty and the Beast. 
In addition to these basic specs my primary reasons for choosing these Electrodyne brutes include:

  • truly rugged “beastly” construction and weighing in at 40kg / 88 lbs each
  • Beautiful simplicity with only one moving part, the stator shaft and no moving electrical parts
  • More simplicity being Brushless with no brushes and no brush springs
  • One piece steel “double ended” housing with TWO alternators; one at each end.
  • Remote Rectifier which moves most of the performance robbing heat outside the ER
  • eXceptional life with 20,000 hours  between recommended servicing

PXL_20201124_135938081Here is what one looks like in real life.  The box on top is simply a junction box where the 6 (3 from each alternator)AC current carrying wires emerge from inside the alternator body and connect to six large cables that go to the remote rectifiers outside the ER in the Workshop.
I ordered these alternators directly from Electrodyne in Oklahoma almost 2 years ago and spent a LOT of time with Dale Gould who is the Operations Manager at Electrodyne and he has been truly fabulous to work with on every level from getting these beasts built to the specs we decided upon, getting them shipped to me (not as easy as it sounds) and even creating little how to videos to show me how to do the alterations I needed on my end.  Can’t thank Dale and his team enough nor recommend them more highly to you.

PXL_20201123_125232591In the interim, I ended up changing how and where I was going to mount these two beastly beauties on Mr. Gee and so I now needed change the location of these Junction Boxes from where I had originally asked Dale to position them.  Not a big deal and I always welcome any chance to get “up close and personal” with every bit of kit on Möbius as I’m also the guy that needs to maintain everything and keep us up an running at all times in all conditions.
PXL_20201124_134411083The aluminium Junction Boxes are bolted to the steel housing and to reposition them I needed to re-drill and tap (thread) four new holes for the new position. 

First step was to remove the two pressed on aluminium ROTORS which have all the permanent magnets embedded in them and rotate around a few millimeters away from the stationary Stator coils you see here.
PXL_20201124_134037297With the Non-Drive end Rotor off I could now remove the Rotor on the Drive end by pressing out it and its shaft from the internal hub and bearings inside the case.
PXL_20201124_134032959This close up of the inside of the AL Rotor let’s you see how all the permanent magnets such as the two I’m pointing at here, are embedded into the AL Rotor.
PXL_20201124_120154113I know this is riveting Show & Tell for so many of you, NOT! but the disassembly goes pretty quickly from here so I’ll speed through the process even faster for you from here.

Top Lid comes off the Junction Box enabling me to disconnect all the wires from their studs in the sides of the Junction Box body.
PXL_20201124_115044100Each set of Stator windings, one at each end, can now be unbolted and …….
PXL_20201123_135125891…… pulled off of their tight fit to the central hub inside the housing allowing me to now carefully pull the three large gauge solid copper wires and terminals out through the holes in the housing one at a time.
PXL_20201124_115805591One end Stator windings removed, ready to spin around and do the same to remove the Stator windings on the other end.

Removing 4 Allen head bolts, one seen in the bottom Right here, let’s me remove each Junction Box.
PXL_20201123_151212610Full dis-assembled now!

Possibly resembling Dr. Frankenstein’s workbench I am already LOVING my new Workshop and all 11 meters of workbenches!
PXL_20201124_084516773I marked the new location of the Junction Boxes with felt pen and so now it was a simple matter of lining up the 2 holes in the bottom of the Junction Box with the new holes in the housing and clamping them in position.  I could then use the 4 bolt holes in the Junction Box as a template to mark the corresponding center marks to drill into the housing.
PXL_20201124_105407408I had carefully taped off all access to the inside of the housing to prevent any metal chips or dust from getting inside and it was a bit tricky to drill the 4 holes into the housing at this angle but it worked out fine and I could then cut the 10-32 threads into the housing with my tap set.
PXL_20201124_112801551And now re-attach the Junction Box in its new permanent location on the housing with the 4 Allen head bolts you see here in each corner of the Junction Box.
PXL_20201124_120148496The trickiest part of the reassembly was fishing the thick stiff solid copper wires back through the hole in the Junction Box and housing as they just barely have enough room to fit through and the hole is behind the Stator windings, but it all went smoothly and I soon had all 6 Stator wires and both Field Wires all back in place and ready to connect to their awaiting studs in the sides of the Junction Box
PXL_20201205_072756095One done; one to go!

But I need to wait to mount the Junction Box on the lower Big Red #2 on the side of Mr. Gee as you saw above because I need to strap it in first and THEN I can bolt the Junction Box to the housing OVER TOP of the strap.
PXL_20201204_093851598As you can see, all my trial and fit had made a bit of a mess so I needed to put back some of the Beauty into these two Beasts with a good sanding and repainting.
PXL_20201204_093900588I just happened to have this short little Jack Shaft left over from another project and in a lovely stroke of synchronicity it worked out to be the Goldilocks solution to drive Big Red #2 from the gear driven PTO on Mr. Gee.  So it needed a matching paint job as well.
PXL_20201205_064102850.MPWith all the openings and AL rotors all plugged and masked off it didn’t take me long to shoot these with three coats of Red International “Perfection” epoxy. 
PXL_20201205_072756095Although it was not the ideal shade of Red, a bit on the orangey side ….
PXL_20201205_072804595…… they definately looked better than when I started and were now all ready to be installed onto Mr. Gee. 

Hopefully Dale and all his team at Electrodyne will like what he sees too.

Now let’s quickly get onto the mounting of Big Red #2!!

I will try to mount BR#1 next week so stay tuned for more scintillating story telling then! Smile
PXL_20201209_120140437By now I was getting pretty quick at mounting BR#2 to the side of Mr. Gee and I wanted to do one final test fit of the Junction Box to double check that everything really did clear.
PXL_20201209_120133890To my absolute joy and delight everything just barely cleared!  Click to enlarge this photo or any other and you can see how close some of those fits are.
PXL_20201210_143350130If you look closely you will see that there are a LOT of close fits! 
PXL_20201210_143415830I think this must be some polar opposite of Murphey’s Law where the stars align and every close fit actually cleared!

Fortunately for me, mounting Big Red #2 on that upper flat pad you saw earlier will be a breeze compared to this one and I hope to get that done next week and will show you the results.

CHAING STOPPER:

PXL_20201207_121636753Up at the Bow on the Anchor Deck, we needed to install this latest bit of boat jewellery; our gleaming solid SS Lewmar 13mm Chain Stopper!

It is a very simple system that can become eXtremely critical if your snubber line breaks in a big storm and you need to have a way to “for sure” hold your anchor chain to the boat no matter what.  Yes, ask me how I know!
PXL_20201207_120350060Uğur and I quickly sketched up the design we thought would work best to solidly bolt this Chain Stopper to the deck framing and he had it all fabricated out of 20mm / 3/4” AL plate and was welding it to the Anchor Deck plate.
PXL_20201207_132430429Simple arched platform that elevates the Chain Stopper to be at the correct height of the chain as it comes off the gypsy chainwheel on the Maxwell VWC 4000 windlass and then the Chain Stopper is through bolted with 4 M16 SS bolts and nuts.
PXL_20201207_134200667A bit of Blue Threadlocker to make sure these never come loose but are still easy enough to unbolt if ever needed.
PXL_20201207_151922644One more “little but important” job done and checked off the list.

ELECTRICAL WORK:

PXL_20201208_074929996.MPHilmi was a welcome addition back on Team Möbius this week and he was right into the same theme of completing many more of those little but important electrical jobs.

He started with this one; putting in the connections for Mr. Gee’s two G31 FireFly Carbon Foam starter batteries.


PXL_20201208_075003433First Hilmi mounted the Red Start Battery Shut Off Switch and ran the cables from there to the Battery Box locations.
PXL_20201209_071928930Each battery will be enclosed in it’s own dedicated plastic battery box and mounted at the very far end of the Stbd/Right side wing of the Workshop underneath the Day Tank and up against the WT Bulkhead there.

They go forward another 40cm/16” from here and their lids just clear the 127mm/5” rubber exhaust hose that runs overtop of them.

PXL_20201209_071914716Now time to tame all these electrical snakes slithering out of the Engine Room!
PXL_20201209_083259750One of the best features of our decision to put in a dedicated Engine Room enclosure is that we can keep this an “Engine only” Engine Room and locate almost everything else OUTSIDE the ER where they are much cooler, easier to access, less likely to be exposed in the case of fire and much easier to comply with all the ABYC and CE fire safety requirements. 

No batteries, no electronics, no fuel filters or tanks; nothing but Mr. Gee and his immediate systems such as heat exchangers and exhaust.

What wires we do need to bring inside the ER, mostly for the Electrodyne alternators, come through this one penetration under the floor of the same Stbd wing of the Workshop on the other side of this photo.
PXL_20201209_110130702Hilmi takes it all in stride as usual and he, Ramadan and Cihan soon have the new cable trays in place ……
…… PXL_20201210_143215673and start routing and fastening the cables in place alongside …….
PXL_20201210_143228988.MP…….  and then under Mr. Gee.

Cihan does EXHAUSTING WORK!

PXL_20201202_120607019Möbius’ Engine Room was a busy place this week as Cihan and Ramadan installed the Halyard Exhaust System which has been patiently waiting its turn down on the shop floor underneath Möbius for many months now.

As you might have noticed in some of the photos above, I had already installed the flexible SS woven mesh that bolts vertically to the aft end of Mr. Gee’s exhaust manifold.

So the fist part of the “dry” section of the Halyard Exhaust components to go in was the75mm/ 3” ID vertical SS riser you see here rising up here in the lower Right corner.

The two “wings” on this riser are where the two support rods will connect down to Mr. Gee to help stabilise them.
PXL_20201202_124011317My personal favorite bit of kit from Halyard is this beautifully crafted and polished SS water injection elbow which Cihan is assembling to its silicone bellows.
PXL_20201202_124021624Peering down for an inside view, you can see how the water jets are all distributed evenly around the inner circumference and make sure there is a very even spray and mixing of the seawater that is pumped through them with the exhaust gases exiting Mr. Gee. 

This is where the exhaust changes from dry to wet and where most of the noise and the heat is removed by the mixing of the seawater and the exhaust gases.
PXL_20201202_123902462Simple job now for Cihan to slide the soaped up silicone bellows to the awaiting downward angled 127mm / 5” pipe on the Halyard “Combi” Silencer/Separator that has previously been mounted on its dedicated shelf on the front ER WT Bulkhead wall.
PXL_20201202_142018661.MPAlmost a year ago now, Yigit and I had spent several months working with Oliver and his team of engineers at Halyard HQ in the UK to design this Goldilocks Exhaust System for XPM78-01 Möbius.  Together we exchanged countless 3D models that we were each creating and so it was wonderful to see this all fall into place like an accurately cut jig saw puzzle.
PXL_20201202_142009961.MPEven Cihan, who has installed countless exhaust systems in the many other yachts he has worked on was very impressed and asked “How did you DO that??!!”
PXL_20201202_143501699With everything dry fitted and checked Cihan and Ramadan could now tighten up all the connecting bolts and SS hose clamps.

Using plenty of Tef-Gel on all threads of course!
PXL_20201203_123545070All that remained to be done was install the three rubber hoses needed to complete this Goldilocks exhaust system.  Over on the far Left side is the Black 75mm/3” ID hose that quickly takes all the seawater in the bottom of the Silencer/Separator down to the dedicated AL pipe welded into the exiting Sea Chest and out to sea.

Next over to the Right is the White hose that delivers the fresh cold seawater up to the inlet pipe on that SS mixing elbow.

And then the large 127mm/5” ID Black hose transports the now cool and quiet exhaust gases from the Combi down and over to the AL pipe welded into the Stbd ER wall where it then connects to another short length of the same rubber exhaust hose and out the similarly welded in place AL exhaust exit pipe in the hull just above the WL.

DIVINE DINETTE TABLE & PEDESTAL SYSTEM:

Last I have time to cover in this week’s Show & Tell is yet another bit of boat jewellery and Rosewood; our Dinette Table!


PXL_20201207_092001988It was love at first sight for me about 2 years ago when I first spotted this Triton Deluxe 2-stage table pedestal at the Zwaardvis booth at the big METS Marine Trade conference every year (except this one of course) in Amsterdam.

This is the fully lowered position which lowers the surface of the table to be flush with the surrounding seats where it can then become an additional Queen bed on those rare occasions when we have more quests, or more likely more Grandkids aboard than can be accommodated in the 2 beds in the Guest Cabin.
PXL_20201207_091906231Simply rotate those 2 SS handles and the air assist gas cylinder inside pushes the pedestal up to proper eating/working table height.
PXL_20201207_091915319But WAIT!  There’s MORE!

Check out that Kissin’ Cousin from Zwaardvis sitting to the side of the Triton pedestal!


Triton X-move sliderThis is the Triton T-System X-Move slider which allows you to slide the table top 200mm / 8” in the X or Y, Fore/Aft or Left/Right direction
PXL_20201207_093536309by simply pulling this lever which mounts under the table.  In the normal “fixed” position that little rectangular rubber pad on the Right is pressed up against the underside of the table and locks the table in whatever position you want.  Pulling the hand pulls the rubber down allowing you to push/pull the table wherever you want and then release the lever to lock in that position.  Brilliant!
PXL_20201208_095454023Over in the Cabinetry shop Ramadan #2, our newest Cabinetmaker has been busy building the Dinette Table top I designed.  Very simple and sturdy, it has 50mm/2” thick solid Ro$ewood edges surrounding a Rosewood laminated plywood table top.
PXL_20201208_095510680Ramadan cut this hardboard template so we could try it in place in the Dinette on the Triton pedestal and slider and check out the clearances with the table in all its different X, Y and Z positions.
PXL_20201208_095520688Once we had it just right, he was able to laminate both sides of some 20mm/ 3/4” marine plywood …..

All ready to have the large radii shaped into all these solid edges, sanding, filling and varnishing and I will soon be able to show you this next bit of beautiful art work aboard the good ship Möbius.
Well as usual I have much more to show you but I’m pooped, swollen and hungry as it is now after 21:00 here in Antalya on Sunday night so I’m going to call it quits for tonight and be back with much more next week.

Thanks SO much for taking time to get this far and join us on this grand adventure.  As always we REALLY appreciate you adding any and all comments and questions in the “Join the Discussion” box below so don’t be bashful now!  Your feedback is invaluable and VERY much appreciated.

Hope to see you here again next week.

I can’t Handle it! Sealing Chain Bin has Treaded and Exhausted me like a Dog! Progress update XPM78-01 Möbius Nov 30-Dec 5, 2020

This week’s title is a bit of a riddle for you so see if you can figure out why I’ve strung together these words to summarise the progress on XPM78-01 Möbius this past week of Nov. 30th to Dec. 5th, 2020?  And Yikes!  someone please tell me that it is not already December and the end of 2020?!?!  While I’m sure that we are all going to be somewhat happy to see this wild ride during 2020 come to an end, I do still shake my head as to how it can be possible that another whole year has flown by?!!  So now looks like it won’t be till 2021 that XPM78-01 Möbius launches but trust me, it is all hands on deck in the most literal of ways with Team Möbius as we all recommit ourselves to “git ‘er dun” mode or as our 4 year old Granddaughter is fond of exclaiming; “Let’s DO this!!”

We are now hoping, emphasis on the hope part, to actually “Splash” or Launch her before the end of February now.  However, the actual Launch Date remains the same as I’ve always answered that question; “Thursday”!

I will apologise in advance that I’m going to rush through creating this week’s blog posting as it is already mid afternoon on Sunday and it has been a truly exhausting week, both literally and figuratively, which is a clue as to the riddle of the title I mentioned above.

But enough with all this preamble get yourself a favorite beverage and a comfy seat and let’s jump right into this week’s Möbius Show & Tell.

“Little Jobs that add up to be a BIG Deal!

As with most big projects, at this late stage of the build there are a LOT of different jobs getting done as we all pull together and work on the punch list of jobs remaining.  Some of these are quite small and continuations of jobs that I’ve covered here extensively in the past so rather than whole sections for each of these, let’s just blast through a few such “little jobs”, all of which add up to a BIG deal BTW.

PXL_20201130_090310442If you have had a chance to follow along over the past month or so you’ve seen the installation of these two etched glass walls that form the corner of the shower in our Master Cabin.  All thanks to the incredible talents of our dear friend Sherry and if you have not read the blogs in the past month where I’ve provided all the details and links to Sherry’s other art work, I can highly recommend taking the time to do so.

This week the glass installation contractors returned to finish the silicone seals around the perimeter of each glass panel and our Cabinetmaker “Ramazan” (pronounced Ram-a-Dan” in Turkish) installed the Ro$ewood trim board that run along the top and bottom exterior edges.


A bit hard to see in this photo (click to enlarge any photo) but I thought this backlit shot helped to show you Sherry’s etched artwork and just how truly “kewl” our Shower looks.


PXL_20201201_135916883Adding significantly we think, to the overall artistic feel and “pop” of our Master Cabin Shower and Head/Bathroom is this additional work of art & engineering, our blue hued solid tempered water glass VIGO vessel bathroom sink!


PXL_20201201_135928699Cihan was busy this week installing this Vigo sink and its very complimentary, we think, black faucet.

The oval shaped matching kissing cousin to this rectangular sink is just outside the door into the Head/Bathroom at our Vanity Sink area at the very front end of the Master Cabin.
PXL_20201201_134925135Captain Christine came into the shipyard earlier this week to work on completing the assembly of our LiteMax Durapixel 43” sunlight readable monitor that goes up in the forward Starboard/Right corner of the SuperSalon.  After a LOT of searching, we finally found LiteMax in , New Taipei City Taiwan and purchased all  5 of our big sunlight readable monitors from them and had them shipped to us here at Naval.
These 2 phots show how I simply attached each board to the aluminium back of the monitor with a SS machine screw that I epoxied in place.
PXL_20201201_134931161This 43” Durapixel model is part of their “Industrial Display” product line which are used for applications such as ATMs, airport displays, etc. and the metal case on the back of these was going to take up too much space for us so we ordered it with just these 3 circuit boards that are needed for the power supply, monitor control and all the various input/output plug ins.


PXL_20201202_120641887It was great to see Ramazan working on these templates that he will be using next week to cut out these counter surfaces that set atop each of the two Vent Boxes out on the Aft Deck to create our Outside Galley. 

This is the Vent Box/Countertop on the Port/Left side where the sink and faucet will live.
PXL_20201202_120629874.MPAnd this is the two tiered counters on the Stbd/Right side where our electric Kenyan BBQ/Grill will go.

Ramazan will use these templates to cut each countertop from the “left overs” of Turkish Turquoise Marble that we used to build all our Galley countertops.  We are totally “Gobsmacked” as my British friends might say by the looks of this Turquoise Turkish marble slab we found and were delighted that there was just enough left over to let us use them for these Outside Galley countertops.
PXL_20201202_120647195.MPThis shot taken from just outside the WT Entry door into the SuperSalon looking towards the Aft Stbd corner of the boat will give you a better sense of the size and scale of the Outdoor Galley.

The big “hole” between them is the big access hatch into the Engine Room below which will normally be closed with its all AL hatch door which you will be seeing a bit later here.
PXL_20201204_084607219.PORTRAITOn the Port/Left side just opposite the Galley, Ramazan was busy putting the finishing touches on the installation of our two Vitrifrigo 70 litre/18.5 USG drawer freezers.
PXL_20201204_084634506.PORTRAITThese are the latest models from Vitrifrigo and one of their very cool  features (sorry couldn’t help myself) is that you can configure them to be anything you want from slightly cooling vegetable storage fridge all the way down to a rock hard freezer at -20° C / -4° F. 

Making this change could not be simpler as all you do is change the temperature setting on the digital thermostat touch screen on the front of the drawer.

No space given up inside for the compressor as we ordered the models with remote mounted compressors and they are all down in the Basement below.
PXL_20201204_094057386

We are very impressed by the quality of Vitrifrigo products with examples such as these robust all SS drawer slides, the well done HD coiled cord to connect the sliding drawer to the door mounted thermostat and the beefy rubber self closing gaskets/seals to keep all the cold in and the heat out.

Once we launch and start using these we will be able to report on our overall electrical loads for our four fridge/freezers but we expect them to be very efficient.  In addition to the already very good insulation of these units themselves, we have also installed them in cabinets that have 50mm/2” of rigid foam insulation around all 4 sides and backs.


PXL_20201204_094111687Built in fan as you can see here to keep the air circulating and consistent throughout the whole freezer.

Having a total of 140L / 37USG of “freezer” space on top of 260L / 69 USG of refrigerator space is going to be true luxury for these two ex-singlehanded sailors who are used to MUCH smaller single top loader fridge/freezers where what you want is ALWAYS at the very bottom!
PXL_20201204_094214673Last but definately not least for our run through some of these “little” jobs, Nihat has now pretty much finished his HUGEY task of putting the final finished appearance on the seeming acres of all our exterior exposed bare aluminium surfaces. 
PXL_20201205_071026019These 2 photos are of his handiwork in the Upper Helm Station in the SkyBridge.
Llebroc Upper Helm ChairIt is currently all wrapped up in protective plastic right now but just out of view in those photos above is THIS beauty that is patiently waiting to be bolted into that Upper Helm Station! 

I had put a Llebroc Helm Chair in my previous sailboat Learnativity and as a full time single handed passage maker I quite literally lived in that chair for weeks at a time on long passages so I speak with some authority when I say that these are VERY comfy helm chairs!


I purchased that first Llebroc chair back in 2006 and they have had a LOT of improvements since so we were pretty sure we wanted to “go with what we know” but we just to make sure Christine and I went to every seat manufacturer at boat shows for over 2 years and tried out all of them.  We also did a number of deliveries on other boats all with different seats so we had extended opportunities to test out many other seats.  But, our bottoms and backs voted VERY clearly; Llebroc was the hands down Goldilocks Helm Chairs for us.


PXL_20201123_071233863.MPAnd this is the slightly different Llebroc Bandera Series 2 helm chair  we are about to install down in the Lower Helm Station.  It is a bit wider and a bit lower back so it is still super comfy but doesn’t get in the way of our 360 degree views outside the SuperSalon.
PXL_20201123_071306466When you are “conning the helm” for hours at a time you usually want to be sitting up nice and high so both chairs have over 18” of vertical “air lift” adjustment.  When you are sitting up high though your feet can’t touch the floor which becomes very uncomfortable quickly so both helm chairs have these robust foot rest platforms which can be folded up out of the way when you are sitting lower.
PXL_20201123_075451372These foot rests shipped separately from the chairs and it didn’t take me long to bolt them on with the supplied SS Allen head bolts. 

I am a bit fussy, OK, some say obsessive, about coating ALL threads and especially SS ones or ones where there are dissimilar metals involved, with a good coat of TefGel hence that little white jar in the foreground.  but trust me it is SO worth this extra step to have fasteners that come out as easily as they went in 20+ years ago. 

And yes, you can ask me how I know!
PXL_20201123_075515183Another great feature is that our Llebroc Helm Chairs are mounted on these Mariner 2 Sliders which  provide 210mm/8” of fore/aft travel on these AL rods.

All the framing and primary parts of the chairs, pedestals and swivels are solid cast aluminium so everything is eXtremely rigid and solid.
PXL_20201123_071609316However, for this aging sailor’s badly damaged spine, THIS Is my favorite feature, the manual pump adjusted Lumbar back support!  You have to use one of these to appreciate just how awemazing and once again, yes you can ask me how I know?!!
PXL_20201123_071245508.MPEven though it is just temporarily in place and there is much to be finished around it, this Helm Chair will be seeing a LOT of use by both of us as we get back to sailing the world from either our upper or lower helm stations.

HATCH SEALS:


PXL_20201202_120615989.MPOne of Ugur’s “little jobs” this past week was installing all the big thick EPDM rubber gaskets in all the three big all aluminium hatches on Möbius.  This is the biggest of the three hatches, the one overtop of the Engine Room. 
PXL_20201202_120619336Even though they only have one job, keeping these hatches completely watertight no matter what forces of sea water is crashing on deck and trying their bet to get through, these gaskets are eXtremely critical. 
PXL_20201202_091803759.MPOne of these hatches is this one up at the Bow sealing off the whole Forepeak area below and there will undoubtedly be times when we “bury the nose” into some huge wave so you can imagine the water pressure that these seals need to keep out.
PXL_20201202_091800963It took me a bit of time to run the calculations and scenarios needed to chose the Goldilocks “just right” Durometer hardness for these seals.  They need to be hard or stiff enough to seal well enough to keep out all that water pressure and yet they need to be soft enough to “squish” just the right amount when you close them and “dog” them down with their big beefy latches which I will show you in a bit below.
PXL_20201202_152743519To add to the challenge the width and thickness of each of these hatch gaskets/seals needed to be different to match their construction.  This EPDM gasket on the ER Hatch is 40mm / 1.6” wide by 25mm / 1” thick and this shot shows how Uğur has done a nice job of gluing this seal in place and holding it to bend around the short radius on each corner with some temporary blocks.  This way he could install each seal as one long piece with just one butt joint about half way along the length of the ER Hatch. 

All of these EPDM seals are firmly glued in place with Sikaflex industrial adhesive so they should serve us well for many, many years.

HATCH DOGS & HANDLES

                 ?? have you twigged to the riddle of this week’s title yet??

PXL_20201204_065314463Of course those EPDM hatch seals can be as fabulous as you like, they are not going to do much sealing if they are not eXtremely well dogged down when closed so that they get that Goldilocks Just Right pressure to squish the Just Right about to form the Just Right watertight seal.

And THAT is what these bits of boat jewelry are for!

This is one of 14 Bofor Dog Locks & Handles which Uğur spent much of his time installing this past week.
Bofor AL Dog Handles snipBofor is one of our favorite Turkish companies we have found while building Möbius and you may remember that name as we also turned to Bofor for all our WT Doors on Möbius.

BTW, the “Brass roller” indicated here is a typo and as you can see in the photos the roller is actually Black Delrin so no concerns about having Brass and Aluminium touching each other which is a corrosion No-No.
Bofor Dog Locks   Handles snip

This dimensioned drawing above and this illustrations below will give you a good idea of how these Dogs and Handles work and the quality of their construction.
PXL_20201204_065305848One example of the eXquisite quality of these Bofor products are the SS ball bearings that enable us to dog down these big hatches with tremendous clamping force and yet be smooth as butter when doing so.


PXL_20201204_094445650One of my other many “obsessions” besides prodigious use of TefGel is to not have very clear clean decks with no “toe-stubbers” allowed.  Hence our use of these flush mount Bofor Dogs.


PXL_20201204_133008815.MPIn addition to being very good looking, these flush mount Dogs are also super practical as we open them with the same winch handles we use for our winches using this rather universal “star pattern” SS fitting. 

Simple 1/4 turn to close or open.
PXL_20201204_094455478Here is how the four flush mount Dogs look on the Forepeak Hatch which Uğur has now completed and reinstalled on its hinges and dogged down to check for fit.
PXL_20201204_094508073.MPThis is what those four Dogs and their anodized aluminium Handles look like from the inside when the Forepeak Hatch is open for business.
PXL_20201204_084044648A bit closer look for those of you interested in a more detailed look at how these Dogs and Handles work.
PXL_20201203_122359063The Dogs on the ER Hatch are too high to reach so they only have the “Dog” portion and not the Handles but they operate the same way from up above using a winch handle.
PXL_20201204_064747782Simple though them may be, installing these Bofor Dogs & Handles takes great care and attention to mount them in just the right position. 

The process begins with Uğur carefully laying out the location of the through holes for the body of each one has just the right amount of purchase on the AL frames underneath for that Delrin roller to rotate on.
PXL_20201204_064837519The body of the Dog Lock is then inserted into the hole and the AL collar in the foreground is threaded onto it from the underside. 
PXL_20201203_150844878Down inside the Engine Room there was another bit of detail for Uğur to look after which was that the AlucoBond panelling inside the ER was in the way of the dogs.

This one at the far Aft end of the ER Hatch also needed to clear this clear water hose which is the drain from the six holes in the “gutter” around the full perimeter of the ER Hatch.  We can’t have water dripping on Mr. Gee when we open his hatch now can we??!!
PXL_20201204_130849432[3]But didn’t take Uğur too long to cut out the AlucoBond paneling where the Dogs need to be able to swing as they close to grab onto the AL frame you can see here.
PXL_20201204_135458687Last but not least was this vertical mounted Hatch/Door on the HazMat locker on the Aft Swim Platform.  We will often have some big following seas which can sometimes break and really “poop” the whole Swim Platform and Aft Deck so equally robust seals are needed here as well.

TREADMASTER!!

PXL_20201202_120729232The star of the show this past week in terms of exciting milestones for Christine and I to see when some of the newest members of Team Möbius started installing the TreadMaster that will cover any and all exterior aluminium plates where we walk. 

The decks are the most obvious but this same TreadMaster will go onto all stair treads, tops of hatches, around winches and the floors of the SkyBridge and the Tender.
PXL_20201204_084150015TreadMaster is made in the UK and has been a standard non-slip surface on boats since 1990.  It is quite a fascinating material as it is eXtremely soft and flexible as you can see here so it can perfectly follow most any surface.  Yet at the same time it is also eXtremely tough and we have been on boats with TreadMaster decks that are over 20 years old and still working well.
PXL_20201204_131556059.NIGHTI took this close up shot to show you how the non-skid works with all these sharp edged diamonds cut about half way through the 5mm thick Treadmaster material.
PXL_20201204_094337064Tools of the Trade for applying Treadmaster include lots of West Systems epoxy with colloidal filler to get just the right “peanut butter consistency”, some V-notched spreaders and a very skookum roller for squeezing out the epoxy to just the right thickness.
PXL_20201201_140811208Let run through a rapid-fire set of photos to show you the overall process we came up with for installing all our TreadMaster on Möbius.

First they glue down registration strips of thin plywood that are 20mm / 3/4” wide, the width of the gap we wanted between each piece of TreadMaster.

PXL_20201204_131641665Each corner of each sheet has a 30mm / 1.2” radius that is cut with a special cutter I made up out of a short length of 60mm SS pipe with a 90 degree section of the edge sharpened with my Dremel tool.  This made quick work out of the hundreds of corners that needed to be cut and kept them all the same.  These rounded corners prevent any lifting that a sharp 90 degree corner would likely experience and looks great to boot.

PXL_20201204_131308728Once each sheet is cut and dry-fitted, it is removed and the underlying AL deck plate is given a light sand with some 120-180 grit sandpaper to remove the oxidized layer that natural forms and protects raw aluminium surfaces.  This is a very desirable trait of aluminium that naturally protects all our AL surfaces but adhesive does not stick as well to the oxide layer so it needs to be removed to expose “fresh” clean AL for the adhesive epoxy to bond to.

Last bit of prep is to thoroughly clean the whole AL surface with clean cloths soaked in Acetone.


PXL_20201204_131658271Time to mix up the epoxy adhesive now!
West Systems epoxy pumps in cans west-system-301a-epoxy-resin-pump-set-1508338222-lWest Systems makes this very quick and easy with their pump system; One pump of Resin + one pump of Hardener and you are good to go!  Such a brilliant system!
PXL_20201204_131741076TreadMaster’s detailed installation instructions specify a “peanut butter” consistency and explicitly caution against one of ketchup, mayonnaise or yogurt.  To do so requires the addition of High Density 406 Colloidal Silicone filler mixed at a ratio of 1:1 by volume with the mixed epoxy.
PXL_20201204_131907113Thorough stirring produces the just right Peanut Butter, smooth and creamy, not “Chunky” thank you very much and it is ready to be applied to the shiny clean AL deck surface.
PXL_20201204_132025481The peanut butter can be applied to either the TreadMaster or the AL deck but we found that it worked best to apply to the cleaned AL surfaces because you could really force the epoxy to stick to the entire surface right up to the edges and know for sure there were not missed spots
PXL_20201204_132210992Now the V-notched spreaders come into play and provided an easy fool proof way of getting the just right thickness of the epoxy mix across the entire surface.
PXL_20201204_132244580.MPNow those fast glued registration guides come into play as the previously cut piece of TreadMaster now easily set into the just right position by simply pushing the piece up against the edges of these guides.
PXL_20201204_132247410The piece can then be quickly set in place by hand making sure that the edges in particular are all perfectly referenced against their respective guides.
PXL_20201204_132302202.MPNow that hefty multi roller tool comes into its own by allowing you to put your full weight onto it as you rapidly roll out from the center to each edge thereby ensuring that all the epoxy is firmly and evenly squished and …….
PXL_20201204_132349704 … that you get the same amount of squeeze-out around all the edges
PXL_20201204_132720324Any uneven amount of squeeze-out can be easily seen and fixed with some added thumb pressure.
PXL_20201204_132723690And then the ultimate tool, your finger, forms the just right coved surface on the epoxy as it makes the transition from the AL deck to the TreadMaster edge.
PXL_20201204_132731108.MPThe fast glued registration guides can be quickly popped off with light tap with a chisel and you can now go over the entire edge of the finished sheet.
PXL_20201204_084214993Rinse and Repeat 100 times and you’re all done!
PXL_20201204_084157027Orkan, who is also Naval’s “Teak Deck Guy” was in charge of doing all cutting each sheet of TreadMaster to their Goldilocks Just Right size with their appropriate radiused corners and here he has got the Stbd/Right side Deck all covered with dry-fitted TreadMaster.
PXL_20201205_081650598He was in with me on Saturday, along with Faruk and Ramazan to take advantage of this quieter and dust free time in the shipyard and here is cutting and fitting the sheets on the Port/Left side of the Aft Deck.
PXL_20201205_081758434.MPMeanwhile, Faruk on the Left and Ramazan teamed up to glue down all the Port side sheets on the Foredeck.
PXL_20201205_143159066As the winter darkness came on and it was quitting time on Saturday, Orkan had finished most of the Port side of the Aft Deck and we were all VERY pleased with how quickly and how well this whole process had worked.

Next week should see all the rest of the TreadMaster applied though it becomes slower as you do the smaller areas such as stair treads and such but I will show you all that next week.

CHAIN BIN FULLNESS

PXL_20201202_064235373Somehow amidst all that went on this week I was able to finish putting Big Red 1 & 2 together, our two 250A @ 28V Electrodyne alternators and get them all painted and ready to install  But I’ve promised several of you to cover them in quite a bit of detail so I’ll do that next week.  But I was also able to build and install the neat grid in the Chain Bin and put all 100m / 330 feet of our 13mm anchor chain so let me finish up with a quick overview of all that.
PXL_20201202_065218799I began by giving the Chain Bin a much needed thorough cleaning after sitting open down in the Forepeak for almost a year now, and then attaching a length of 1/2” Dyneema line to the D-ring welded to the bottom of the Chain Bin.
PXL_20201202_070855423This red Dyneema line runs up through the vertical AL pipe and out the 90 degree hawse pipe in the Maxwell VWC 4000 windlass where I spliced it into the bitter end of the 13mm anchor chain.  The purpose of this line is that if we ever got into a situation where we had to “cut and run” due to severe conditions mixed with an anchor that we can’t get up for some reason, then we would let out all our anchor chain and bring up this Dyneema tail onto the anchor deck where we could quickly cut it with a sharp knife.  No time in such situations to be undoing shackles or going down into the Chain Bin to do this.
PXL_20201202_103623605For some time now, I’d been mulling over the best way to keep as much separation between the galvanized anchor chain and the aluminium Chain Bin as they are a bit far apart on the Noble scale of metals which can cause some corrosion.  I had one of those fun Aha! moments when I realized that the composite grid material that we were using for the flooring in the ER, Forepeak and Workshop would be the Goldilocks solution!
PXL_20201202_103630049We had a bunch of scrap pieces left over from doing those floors so I traced out two half circles the diameter of the inside of the Chain Bin with my trusty Milwaukee “Hacksall” and soon had the two part, for ease of installation into the Chain Bin, all cut out.  I then thought that water and much might get trapped a bit inside all those square grids so out came my Milwaukee angle grinder with a nice thick grinding wheel and made a quick pass down the middle of each row of square grids. 


PXL_20201202_111442977et Voilà!  The Goldilocks Chain Bin bottom was born!
PXL_20201202_111959009.MPNow time to get back up on the Anchor Deck and thread all 100 meters of that colour depth coded 13mm anchor chain into its new home down below.
PXL_20201202_123126927And THIS folks, is the result and what 100 meters of perfectly cone shaped anchor chain looks like inside a Goldilocks Chain Bin!
OK, I’ve got lots more to Show & Tell but I’m exhausted and it is now 9pm and my personal chef par excellence, aka my Captain Christine, has been patiently keeping dinner warm so I’m going to end it here for this week and pick up where I left off.

Thanks for joining and as always, PLEASE add your questions and comments in the “Join the Discussion” box below.

Till next week,

New Arrivals = Mount Up! XPM78-01 Möbius Progress Update 02-06, 2020

New Arrivals = Mount Up! XPM78-01 Möbius Progress Update 02-06, 2020

This will be a much shorter blog post than usual (lucky you!) as it was just a one day work week at Naval Yachts this week with them being closed from Nov. 3-10.  However, as usual there was still some very exciting new developments and new arrivals this past week that both Christine and I are anxious to share with you.  The theme this week seemed to be about “mounting” new items that have just been delivered such as mounts for pumps & alternators, mounting computers and mounting/installing glass walls and doors in the showers.  Without further drivel from me, please grab a comfy chair and a good beverage and come along for this week’s Show & Tell here in Möbius.World.

SHOWERS:  Works of Art & Engineering

I’ve been showing you for many months the progress in building the Heads and Showers in the Guest and Master Cabins and our extensive use of glass in both.  This week all these glass panels were delivered to Naval Yachts so we can finally show you what the real thing looks like although you will have to wait for another week or two to see them fully installed aboard.
03For those that are new here or don’t remember, here is a quick rendering of the Master Cabin from the perspective standing in the Entryway door looking forward towards the Bow.  Note the two glass plate walls that form the corner of the Shower in the background of this render.
01Switching locations, here is what it looks like when standing front and center in the Master Cabin looking Aft with the etched glass Shower wall corner in the foreground on the Right.
Sherry working on shower glass imagesWe are SO grateful to be surrounded by so many talented family and friends who very generously and excitedly want to apply their many talents to features inside of Möbius.  Here is one of the best examples; our dear friend Sherry Cooper in her AbFab apartment in downtown Vancouver B.C. working with us on the graphic designs to be etched into those glass corner wall panels.
shine_on_c._sherry_cooperI have known Sherry and her husband Rick since we were teaching High School together on the Canadian jet fighter base in Baden Baden Germany in 1980-84 and to say that Sherry is talented is about as big of an understatement as I know how to make.

To find out more about Sherry and see what I meant check out her other works HERE and HERE as well as her Instagram page HERE.
Christine and I worked with Sherry to describe as best we could what we wanted to achiever with these etched patterns which was things such as a marine/nautical theme, a taste of First Nation people’s art from the British Columbia area we know and love and to have all this captured in a somewhat abstract and ethereal way.

This is what Sherry came up with and we think the nailed it!  A perfect example of our favorite Goldilocks; just right, just for us type of result.
Etched Glass paterns from Sherry Cooper and Hakan vector fileThe sketches above are relatively small hand sketches and we needed to transmogrify these into much larger sizes and be in a CAD/CNC format for the etching work to be done.  Hakan, one of our former Team Möbius members took on this task and created these two Vector based files in AutoCAD which we then sent to the glass etching company.
Shower Glass Wall etchingThe etching company used these vector files to CNC cut these shapes into white peel & stick vinyl which they then attached to the two glass panels and sent us this photo on WhatsApp to make sure this was what we wanted and then they went ahead and did the etching.
PXL_20201104_113555520Here are the finished panels that were just delivered with all the other glass panels stacked on top and set onto a table below Möbius for now as they await being carried onboard to be installed.
PXL_20201104_113618020To give you a bit better idea of what these etched panels actually look like, I slid the glass stacked on top off to the side a bit to shoot this for you and give you a bit better sense of the real thing.

Thank you SO much Sherry!  We LOVE what you’ve done and we can’t wait for you and Rick to come join us and take over the Master Cabin so you can shower within your own “walls of art”.
PXL_20201028_071112613Back in the Guest Cabin we are keeping it a bit simpler with “just” a plain glass door for the Guest Shower that you can see in the stack of glass above and will also soon be installed.

Boat Computer #2


PXL_20201108_070015617We need plenty of computer muscle to power all the sophisticated navigation software, equipment, monitoring and multiple monitors we have onboard the Good Ship Möbius and so Christine has been busy researching, specifying, ordering and building our two Boat Computers.  She finished our primary PC a few months ago and this week the 2nd Boat Computer arrived from the US.
PXL_20201108_070001169This is a Kingdel fanless mini PC which Christine finally tracked down on Amazon US and had shipped over to us here in Antalya.

How fast is this new little guy?  Well, Captain Christine, who is normally an Apple Gal I might add, said “It boots up faster than you can say Windows 10”

Our newest family member will live in the overhead space above the main Entryway beside the SkyBridge helm station which is what it will primarily power.

For our fellow Geeks and Geekettes out there, below is a peek inside and the basic specs:

  • CPU: Intel 10th Generation i7-10510U, 4 Cores, 8 Threads; Comet Lake; 8MB Cache, Base Frequency: 1.8GHz; Max. Turbo Frequency: 4.9GHz.
  • 16GB DDR4 2666MHz RAM,
  • 512GB M.2 2280 SSD;
  • Intel 82574L Gigabit Ethernet LAN;
  • Dual Band 2.4/5GHz Wireless Network Card.
  • Integrated Intel UHD Graphics, 4K: HD, 4096×2304@24Hz; DP, 4096×2304@60Hz;
  • Gigabit LAN Port, HD Port, DP, 4 USB 3.0.
  • Fanless, Smart Design, Full Metal Case, Silent Working, High Speed CPU & SSD, 2 Years Warranty.
  • Pre loaded with Window 10 Pro, complete with full license key for reinstalling.

PXL_20201105_080809030


  • PXL_20201108_070153148
  • This is Christine’s temporary techno test bench in our apartment where she has both Boat Computers hooked up to load up all the software and start configuring them all.


PXL_20201108_070158096Boat Computer #1 is seen here underneath the table as it has a larger “desktop” size which provides much more space for multiple fans to keep things cool, more expansion board spaces and other advantages we wanted.  It is “only’ an i7 9th generation processor but can run all six of our big monitors and will be our main “go to” computer when we are onboard.
PXL_20201108_070115140.MPI thought this shot might give you a better perspective on the size differences although the Mini PC I am holding in the foreground appears larger than it really is due to being so much closer to you in this shot.


Synology NASFor those wondering, the black box on top is our Synology NAS or Network Access Storage.  You can slide different hard drives and SSD’s into this box and right now we “only” have two 4TB hard drives in there but easily expandable and we just took note of two Western Digital drives that are 16TB each for just $200 so we will see if we need more storage and add as we do.

We use all this storage volume on our NAS to hold everything from our huge vaults of music and movies for our onboard entertainment and on them more serious side this also holds multiple sets of electronic charts for the whole world, satellite images, all our manuals for all our onboard equipment, all our software both personal productivity software such as MS Office and all our navigation software such as TimeZero, Coastal Explorer,

Why not just keep all this in the cloud?  We do this too, but this NAS gives us direct access to everything without any internet connections at all.  So this creates what you can think of as own personal “onboard cloud”.

Mounting Jabsco Sea Water Pump
Keel cooler like on LTY

For the Gardner engine cooling, I had wanted to install a keel cooler which is made by cutting lengths of aluminium pipe in half lengthwise and welding these to the outside of the hull with U-turns on the ends to create a continuous loop.  The two In/Out ends are then welded through the hull and the engine coolant (anti-freeze + water mix) is circulated through this loop and transfers its heat out into the passing sea water.  Super efficient, no extra pumps or moving parts required and I had this on our previous boat that worked great.
Heat exchanger closed cooling sytem illustrationHowever, for a variety of reasons Naval switched to a heat exchanger style which works like this.  Sea water is drawn in through the Sea Chest and strainers by an engine driven sea water pump which then circulates the cool sea water through a variety of heat exchangers for the engine coolant, engine oil, transmission/CPP oil and finally goes to the wet exhaust to cool it and then the sea water goes out through the exiting sea chest back into the ocean.  These heat exchanger style works fine and is on thousands of boats, just more complex and more moving parts as you can see.
Bowman heat exchanger external viewAfter some research we chose to go with a Bowman heat exchanger which are one of the world’s largest heat exchanger manufacturers based in the UK and they are beautifully made bits of kit to be sure.
Heat exchanger how it works internal illustrationHere is a generic illustration showing how a heat exchanger works and it could not be more basic; cold sea water enters the large cylinder (Shell Inlet) and flows around all the smaller tubes inside picking up their heat and then exits out the other end (Shell Outlet).  The liquid to be cooled enters the Tube Inlet and runs through all the small diameter rods or tubes that are surrounded y the colder sea water and then exits out the Tube Outlet having given up most of its heat.
Bowman titanium inner tube heat exchangerThat inner “Tube Stack” as it is called is made out of Titanium in ours and you can see that it is simply a bunch of small diameter tubes which are bundled together and have liquid going into one end of each tube and then out the other.
Heat exchanger internal tubes photoI didn’t want to take our Bowman’s apart but here is a similar model that will let you see how the Tube Stack fits inside the larger diameter heat exchanger body where the sea water flows.
Heat exchanger style illustrationSorry, not the greatest quality but best I could find in a pinch here late tonight but this should show you the basic layout and how the various liquids flow through a heat exchanger system.

Jabsco 6400-1051 sea water pumpAs you can see this is all simple enough but it does require the addition of a sea water pump to pull in the sea water through the Intake Sea Chest in the Engine Room and then pump it out through all the various heat exchangers and then finally provide the sea water that is injected into the wet exhaust elbow to cool the exhaust gasses.

I chose this Jabsco 1 1/4” bronze pedestal base sea water pump as I have had these in previous boats and know them and their maintenance quite well.  I like to “go with what I know” you know!
 PXL_20201102_121900903The next bit of “complexity” is that we now need to mount this Jabsco sea water pump and figure out a way to have Mr. Gee drive it.  Cihan has his hands more than full so I have taken on building this mounting system for the Jabsco pump.
PXL_20201102_121907066The Gardner 6LXB often had sea water pumps mounted on them so there is this very solid flat “pad” up at the very front Stbd/Right side of the massive cast aluminium crankcase with three good size mounting studs so that’s where I’ve designed a mounting system to be.
PXL_20201104_133928567Here is the top mounting bracket I came up with all ready to bolt onto that “pad” in the photo above.  Not quite up to Gardner standards perhaps but I assure you it will last as long as Mr. Gee will, aka forever!
PXL_20201104_134454292Difficult to photograph for you but this is what the test fit assembled mount looks like.  The thick AL plate at the top is what is bolted to that pad you saw above which then has the tall thick vertical AL mounting bar bolted to it at the top and an L-bar bracket for the bottom support where I used three bolts on the Sump (oil pan) to hold the bottom of the mounting bar.

The Jabsco sea water pump will bolt about half way along the length of the mounting bar and will be driven by a timing belt type of rubber belt off the Gardner’s crankshaft which you can see off to the mid right side of this photo.
PXL_20201104_134501847

Here is a different view from up above.

The big cast bronze housing is the engine oil heat exchanger which just clears the AL top plate of the upper mounting plate.

The large round cast AL item on the bottom Left with the copper tube snaking upward here is Mr. Gee’s coolant water pump that is internally driven off the camshaft.
PXL_20201104_134527744For the curious and observant of you, the large diameter black disc resting on the crankshaft is the chainwheel for Mr. Gee’s hand start cranking system which I will show you more of later.
OK, that’s it for this week folks.  Sorry it is so short and that we get a much longer work week this week and have more to show you in the next Möbius.World Progress Update Show & Tell.  Christine and I have had a VERY busy weekend and all day today (Monday) helping out two other couples who may become future new XPM owners.  One couple via a lengthy video call (thanks Andrew & Lili) and the other couple who are long time circumnavigating sailors who are here in Turkey for the winter and drove over to spend the weekend with us here in Antalya to meet the people at Naval Yachts and get a full tour of the Free Zone and Möbius.  We had a great time with Wade & Diane who have such a similar history as Christine and myself and we have just said goodbye for now as they head back to their boat which is about a 3 hour drive West along the coast to Alanya.  Great to meet up with you Wade & Diane and look forward to more such visits.

And thanks to all of YOU who chose to join us here on the Möbius.World blog every week.  We really appreciate having you along for the ride and for all your questions and comments that you write in the “Join the Discussion” box below.  Please keep them coming, we prize them highly.
