Moving is the theme for this week, and more next week all of which is a VERY good thing! Albeit eXtremely short trips, literally a couple of hundred yards each, they still represent movement both progress wise and boat wise so it is all good. When I left you last week we had just moved onto one of the many brand new concrete docks not far from the infamous “end wall” dock inside the Free Zone Harbour where we have tied up several times in the past few months since we splashed on Feb. 20th but they had another big cargo ship coming into the port here so all of us tied up on the end wall needed to move to other locations so the Big Guys could come and go. I’ll show you more of that in a moment.
The other even more eXciting moves, yes plural, are hopefullly happening this coming week. On Tuesday we will be moving Möbius out of the Free Zone harbour for the last time and taking her around the corner to Setur Marina where she will officially begin her life as XPM78-01 Möbius. Not sure how long we will be there, basically as long as it takes for Christine and I to get her fully seaworthy and ready to cut the dock lines and head out to sea. I will chronicle all of that here in future weekly Progress Updates so you will get to see what all is involved as it happens.
But WAIT! There’s MORE!!! What could possibly top having Möbius start her own life with us? Easy, because the other big “move” which I am even more eXcited about is that my Beautiful Bride, aka Captain Christine flies back into my arms on Thursday night! She’s been away in Florida having a whirlwind of a time with all her family and friends back there in the Fort Lauderdale area and especially enjoying her much needed Gramma time with our grandson Liam. So it’s been great for her to get away from this non-stop boat work, and even more so jettison out of “Wayne’s World” for two weeks but I miss her terribly and can’t wait to meet her coming out the exit doors at AYT, Antalya Intnl Airport on Thursday.
And as you can see, I’m not the only one who has been missing the Captain.
For those who may not have met them yet, Ruby the Wonderdog is the mass of Black curls on the Left and Barney, aka The Barnes, our Yorkshire Terror at her side. Other than the past 3 years while we’ve been dirt dwellers during the build of Möbius, both of these guys have spent all their lives on boats, and a fair number of planes, trains and automobiles. 14 years worth for Ruby and 9 for Barney so they have a LOT of miles under their paws and more to come soon.
So it is easy to see why “moving” is the theme this week and next and now let’s move on to Showing & Telling you more about all the moves and other progress here on the Good Ship Möbius during the week that was April 19-23, 2021.
As with most posts for the past two months, the primary activity aboard Möbius is the commissioning of all the many bits of kit that make up our many systems.
Not too eXciting to watch quite frankly but eXtremely important to do and get everything right, working and tested. Sometimes we do this virtually, with the technician from the manufacturer coming aboard via the internet and truly eXciting scenes like this one!
Ismail, our electrician, and I are talking with Alex from Victron who is in his office in Istanbul and we have him patched in via a shared desktop on my laptop on the Left which is in turn connected by ethernet cable to the Victron network aboard Möbius, and via WhatsApp on my smaller computer for text and voice.
Together we are able to run and test all the Victron equipment such as the 5 MultiPlus Inverter/Chargers, Isolation Transformer, MPPT controllers and so on. Took us about 5 hours but we were able to get everything configured and they are now all good to go.
Similar virtual commissioning going on with our Kabola KB45 diesel boiler, though it was not so cooperative and we still have more to do to finish the commissioning and testing so we can finally have hot water aboard!
Part of the remaining work with the Kabola is getting this Grundfos Alpha2 circulation pump installed, filled with antifreeze solution and bled. This circulates the hot water for one of the heat exchangers which transfer their heat to our domestic hot water.
Commissioning also often involves some good Houdini skills such as Ismail up on top is demonstrating as they try to get the Kabola lifted up and put into it AL frame bolted to the Workshop shelf it lives on.
Mr. Gee gits ‘er dun!
While he is ailing and I have not had a spare moment to investigate the cause of his sudden loss of oil pressure on the first sea trials a few weeks ago, Mr. Gee was able to power the move here within the Free Zone harbour with no problem.
This was Mr. Gee’s oil pressure at start-up, right around 30 PSI, which for a Gardner is not much below the 38 PSI he normally runs at, however as the oil warms up it drops down to around 20 PSI so there is definately something very wrong that I need to get to the bottom of as soon as we are over in Setur Marina and I can make the time to start digging into the source of the problem.
Unfortunately I am relatively certain that I know what the problem is and it is not good news nor a quick fix. But I will leave all that until I have time to find out for sure what’s going on which means a significant dismantling I’m sure. Stay tuned for more on all that starting next week.
New Neighbors and Neighborhood
You may recall seeing this birds eye view from the last move we did from Setur over to the Free Zone harbour and this aerial view of the Free Zone Harbour on the bottom Left and Setur Marina on the bottom Right will give you a bester sense of the move this week.
Last week were at position #1 on the End Dock Wall and this week we are now back over at position #2 where we were about a month ago.
Next week’s move has us going from #2 over to #3 in Setur although we don’t know just where we will be in Setur just yet.
We are Med Moored in our new home this week, which means there are lines off our Bow as you can see here, which extend out to a massive weight at the bottom of the harbour with all these lines firmly attached. On your way in, you pick up the float that is on the end of one of these lines and bring it aboard while you back down with your stern to the dock.
Like this. It takes a bit of getting used to this style of docking but the key advantage, at least to the marina, is that each boat only takes up its width on the dock rather than its length if you were to be side tied. So you can have a LOT more boats docked on any given length of dock. This is the norm in the Mediterranean and hence the name Med Mooring.
If you look closely at the bottom of this photo you will see how we are able to use our swim ladder for a passerelle or “gang plank” for getting on/off the boat. You can’t really see it but there are massive black rubber fenders or bumpers all along the edge of the concrete dock and that’s what the end of the now horizontal swim ladder rests on. Works well and makes getting on/off the boat quite quick and easy.
This is our new Starboard side neighbor, a brand new Bering 77 “Veronika” which just launched. There was some good press coverage of the launch that you can see HERE if you’re interested in knowing more.
If this boat looks vaguely familiar, there is a good reason for that as you saw this boat two weeks ago when I was showing you the “Launch Fest” going on here when the new 560 Ton TraveLift started working after more then 4 months with no launching capabilities here.
Based on hull length, Veronika is just one foot less than Möbius at 78 feet, however these shots are a great example of how length of any boat tells you so very little about the boat itself or provides any real comparison. This is a much more traditional “Trawler” and so you can perhaps understand why I hesitate when people ask me if an XPM such as our XPM78-01 Möbius is a Trawler?
For a quick comparison, Veronika’s basic measurements first followed by those of Möbius:
- Displacement: 165 metric tons vs Möbius’ 45
- Beam: 7.3m/24 ft vs 5.0m/16.4 ft
- Cruise Speed: 8 kts vs 10-11 kts
- Range: 4000nm vs 8000
- Accommodation: 6cabins, 6heads + up to 4crew vs Möbius 2cabins, 2 heads and no crew thanks very much.
Take a moment to study the differences between Möbius and Veronika and you will quickly see that other than being about the same length, they share almost nothing else in comparison.
You can find the whole set of specs on the Bering 77 HERE if you’d like to learn more and see more photos.
Just so we are clear, it is not a question of which one is “best”, they both are, just depends on your use cases and taste. There’s a boat out there for everyone and every use case. We are just SO eXcited that thanks to Dennis at Artnautica and everyone at Naval Yachts we now have our Goldilocks Just Right, Just for Us, boat!
And that’s a wrap for this past week folks. Lots of activity, just not much visual results to show you but hope you continue to enjoy coming along on this ride with us and that you will be back again for more next week.
In the meantime, please do leave any and all questions and comments in the “Join the Discussion” box below. While I am atrociously behind in responding to your most recent comments, they add a HUGE value to this blog and for Christine and myself and I am eXtremely appreciative of each one so thanks for that!
A VERY busy week here onboard the Good Ship Möbius as everyone on Team Möbius moves into the final stage of the build completing all the installations of equipment and beginning the commissioning of all these systems by their factory representatives and others. Due to a major reconstruction project of the harbour inside the Free Zone * which removed all the previous launching facilities, Naval needed to launch us quite a bit sooner than expected by transporting Möbius overland to the nearby Setur Marina. So in addition to the usual post launch commissioning of systems, we all continue to work our way through the Punch List of jobs needing to be completed in order to get Möbius into seaworthy condition to begin taking her out for sea trials. To say that we are all eXtremely busy would be the understatement of the year! But. for Christine and me, we are even more eXtremely eXcited to be back where we belong, home onboard a boat that floats.
* You can learn all about this huge and fascinating project by watching THIS VIDEO ANIMATION which does a great job of showing how the whole new harbour facility will work.
I hope you will accept my apologies in advance for another hurried weekly Möbius Update as I blast through as much of all the different jobs that we have all worked on this past week. So grab your favorite beverage and chair and join me for this week’s Show & Tell.
Let me start with a quick snapshot leading up to this adventure that began over 5 years ago.
After two years of intense collaborative design work with our AbFab Naval Architect Dennis at Artnautica Yacht Design, the building of XPM78-01 Möbius began at Naval Yachts on April 6, 2018.
1053 days of build time later, as most of you have likely seen in last week’s posting HERE, she finally left that temporary womb last Friday for a watery delivery into her permanent home with Mother Ocean last Saturday.
As I write this blog post from the SkyBridge of our beloved Möbius, we have just finished our first week afloat tied up to the concrete dock wall inside the Antalya Free Zone Harbour.
And I am VERY happy, though not surprised, to report that ALL the sea water has remained where it belongs OUTSIDE of Möbius and our bilges only hold the remnants of construction dust and debris.
Looking all the world to me like two tugs that escaped from a children’s animation story, these two almost new tugs are our most immediate neighbors.
Tied up less than a meter in front of Möbius’ Bow.
These two tugs have crew aboard 24/7 as they are responsible for bringing every cargo ship into and out of the commercial side of the Harbour such as this recent little visitor, the 180m 36k Ton Argo B, who left about 04:30 this morning after loading up with several thousand “Big Bags” of industrial dry goods.
These two tugs are also the Fire Boats for the Harbour. And last night, they surprised and delighted us by bringing over a home made pizza just out of their oven! Can’t think of a better example of why we LOVE living with these awemazing people of Turkey.
Tied up almost as closely to our Stern is this first of four Police boats which are being built by Ares Yachts here in the Free Zone for the government of Oman. These are a bit longer than us at about 26m but share many of the same basic attributes as our XPM-78 with all aluminum construction and built like the proverbial tank.
We even have the same jet propulsion system though in our case just with our Tender and a single not these massive twin jet drives driven by two equally massive MAN diesel engines.
One item that we do not share, YET! with these boats is that mount for a 50 cal machine gun. But rest assured that once I get my 3D printer setup one of my first projects will be to create a realistic enough looking plastic replica to produce a silhouette that will add to our “don’t mess with me!” look to any onlookers thinking of approaching us with mal intent!
I took this shot of our neighborhood early this morning after the Argo B had left and the tugs were back in front of us. The weather has been truly spectacular for the past two weeks with daytime highs reaching 24C/77F and gloriously sunny clear blue skies with very little wind. Not a bad place to spend our first week afloat.
For safety of such a new and incomplete boat, Christine and I are sleeping aboard each night and then going back to our apartment for breakfast and dinner and then we will move aboard full time once all the sea trials are done.
One of the projects I did not have enough time to show you last week was the completion of our rather unique “Sidewinder” anchor roller assembly that Dennis and I came up with so let me show that to you now.
I decided to make the two anchor rollers out of solid aluminium and didn’t take me long to design a 3D model of this in Autodesk Fusion 360 and create the 2D dimensioned drawings to machine them from.
Aluminium is a dream to work with and the in house machine shop has a very good sized lathe that was easily able to machine the two anchor rollers out of a single blank of 200mm/8” OD aluminium round stock.
I wanted to keep the anchor and the chain electrically isolated from the hull to reduce any corrosion problems and was able to do so with two details. One is this Black Delrin bushing which we press fit into each roller with a nice rolling fit for the 40mm/1.6” SS pin that each roller spins on.
The second isolating detail was to machine these Teflon discs that get separate the sides of the rollers from the inside cheeks of the anchor roller assembly welded into the hull. Then a large SS end cap bolts on either end of the SS pin on the outside.
Here is what that all looks like when assembled.
For safety and quiet when pounding into big seas we very specifically designed the whole roller assembly to exactly match the shape of this 125kg/275lb Rocna anchor by obtaining a 3D model from Rocna to design with. The way our design works is that those flared out bottom edges you see in the photo above have been designed such that they exactly match up with the inside of the flukes of the Rocna when pulled aboard and thus the Rocna becomes one with the hull and will not budge no matter what Mother Nature throws at us. This creates not only a very tough and strong anchor mounting setup but also one that does not make any noise due to movement between the anchor and the roller assembly which is so common on many other boats we have run.
So Nihat, Uğur and I spent quite a few hours with the anchor raised on a chain block that allowed us to get the position of the anchor just right and then layout the centers for each SS roller pin. Front pin and roller have been mounted here and we are laying out the location for the 2nd Aft roller.
Uğur and I came up with this idea of building an extended 40mm carbide hole saw so that he could drill both cheeks in one go and keep the two holes for the SS roller pin on the same centerline. We lucked out finding the head of a 40mm carbide hole saw with its shank broken off and Uğur TIG welded a 200mm/8” long piece of 13mm/ 1/2” OD rod to it that we could chuck in my Milwaukee drill. Worked like a charm!
With the rollers both installed we tested it all out with the 13mm / 1/2” chain and the Maxwell VWC4000 Windlass and did a bit of tweaking of the rollers final shape to capture the chain nicely so it stays aligned as the chain goes Out/In and doesn’t twist.
Did not take us long to get to the Goldilocks Just Right point
and “Rocky” was in his new home as solid as his name.
Uğur and Nihat both gave it their thumbs up and so we knew it was good to go!
Another job and details I did not have time to post last week prior to the launch was the finishing of the silicone based International InterSleek 1100SR Foul Release bottom paint and the zinc anodes so let me go back and show you that.
Once the super slick, slippery and shiny silicone InterSleek was fully dry the last few underwater details could be attended to such as mounting the Red plastic prop on the Vetus 220kgf 300mm/12” Extended Run Time Bow Thruster.
Which is capped off with its own Zinc to reduce any problems with corrosion due to the mix of dissimilar metals involved with its construction of Bronze, SS and AL.
In keeping with our Darth Vader, lean & mean look, we decided to make the 100mm/4” Boot Stripe that makes the transition between the top of the Black InterSleek and the bare AL hull, be gloss Black as well and we are eXtremely happy with the result that emerged as the masking tape came off to reveal the final look.
The final detail for the underwater portion of the hull was mounting the ten 125mm / 5” diameter Zinc anodes which keeps all the metal bits that are in contact with seawater all at the same potential voltage and eliminates the battery effect that would eat away at our precious Stainless Steel, AL and Bronze components.
Being near the bottom of the Noble scale of metals, Zinc is what will erode instead and makes it easy to replace the zincs every few years when they get too worn away.
We designed a very simple mounting system for the Zincs and Uğur had previously welded 80mm discs of 20mm / 3/4” thick AL to the hull with an M16 thread in the center for the SS M16 bolt that he is fastening this Zinc on the Rudder with.
To ensure a good electrical connection for many years between the Zinc and the AL mounting disc, we coated those surfaces and the bolt with dielectric grease and then I followed along after Uğur and covered the SS bolt heads with some clear silicone to make it all the easier to remove and replace these zincs in a couple of years. I usually do this while the boat is in the water using my Hookah or Snuba system so these little details all help to make that job go quick and easy.
With all these preparations of the below the waterline areas of the hull and everything removed from underneath, Möbius was ready for the arrival of “Big Bird” the yellow 72 wheel boat mover to arrive the next morning and carry her overland to the marina for launching.
TILLER ARM DETAILS:
Another few details that we needed to look after before Launch Day were for the all important steering system and the Tiller Arm in particular. Similar to the Bow Rollers, last year I had designed this typically over engineered Tiller Arm in Fusion 360 and had it CNC milled out of a single block of aluminum.
Here is a shot from almost a year ago when we first mounted the finished Tiller Arm to the 127mm / 5” OD solid AL Rudder Post.
And here is a more recent shot of what it looks like with the two double acting Kobelt hydraulic steering cylinders in place.
Such a massive Tiller Arm being powered by equally as beefy twin hydraulic cylinders, produces a LOT of force and so there needs to be some eXtremely strong and solid Tiller Arm Stops built in to stop the Tiller Arm when it goes hard over to each side. Fusion 360 to the rescue yet again to help me quickly design these Stops which Uğur and Nihat quickly fabricated and were ready to mount.
After carefully testing out the Just Right position for each stop, they were able to drill the four holes in the AL Rudder Shelf and bolt down one Stop in either side of the Tiller Arm body. The SS bolt and lock nut allow us to adjust the final Stop position of the Tiller Arm once we are in the water and have the steering all working.
I like to practice and live well by what I call “Readiness for the UneXpected” and in the case of our steering system that meant having multiple layers of fault tolerance for the Steering System. This starts with twin independent Kobelt 7080 hydraulic steering cylinders sized so that either one can fully steer the boat in the most adverse sea conditions.
Then two independent Kobelt Accu-Steer HPU400 24V hydraulic Power Pack pumps, two independent Furuno 711C AutoPilots plus two independent Furuno Jog Levers. This gives us eight levels of fault tolerance to go through.
And if ALL of that should uneXpectedly fail, then we have this Kobelt manual hydraulic Steering Pump ……………
……….. that we can slide this Emergency Steering wheel onto and steer the boat the “old fashioned” way.
And if ALL of that should somehow uneXpectedly fail we have THIS final layer of fault tolerance for our steering system; a completely independent and manual Emergency Tiller Arm.
Can’t get too much more KISSS or Keep It Simple Smart & Safe than this; a 2m/6.5ft length of 80mm thick walled AL pipe that slides through the 20mm/ 3/4” thick plate we see Uğur bolting to the Tiller Arm body and then the pipe slides through a matching hole bored through the top of the Rudder Post.
We attach a block and tackle setup on each side of the end of the Emergency Tiller which fasten to shackles mounted on stringers on the adjacent hull sides which allows us to move and lock the Rudder in any position we want.
Yes, I do know that it works and Yes, you can ask me how I know that!
Miscellaneous Work on Deck
Finishing up this blog post is between me and another very late dinner so I’m going to speed through a series of other jobs that got done this first week in the water.
Turkish Turquoise Marble countertops got installed atop both Vent Boxes on the Aft Deck to create our Outdoor Galley.
SS sink plumbed.
And installed in the Starboard/Right side Vent Box.
Plumbing connections all ready to connect to the sink; Red & Blue PEX lines with shut off valves for the Hot/Cold water to the sink faucet, Brass elbow for the sink’s drain and small Blue tube with the Black elbow to drain the water extracted by the Mist Eliminator grills in the Engine Room supply air duct.
Orhan with his home made adaptor for his pneumatic caulking gun ……..
……. to get into some hard to reach spots around the Pilot House windows like these.
Uğur prepping the nylon insert mounts for the Passarella on the Swim Platform and another on the Port side gate.
Ever the ingenious one on Team ,Uğur came up with this brilliant DIY solution for mounting our Fire Hose in the HazMat Locker; an empty plastic spool of MIG welder wire!
Which will rotate on this pipe mounted on the side of the HazMat Locker.
With the Black Fire Nozzle mounted alongside. Any wonder why I just love working with this guy who has been with us from the very first day of the build?!!!
More Uğur Goodness, on Saturday no less, as we designed and built this simple setup for propping the front 3 Solar Panels mounted on this hinged frame up in the horizontal position when we are on anchor.
This horizontal position not only helps out with solar power production but you can see the demister grill across the far end of what now becomes a giant wind tunnel to capture all the fresh breezes blowing over our bow at anchor and funnel them down into the SuperSalon.
Two SS pipes that are hinged to the bottom of the Solar Panel frame and will fit into these Black Delrin collars Uğur machined which were then glued down to the aluminium floor with a SS set screw to lock them in place.
When we are ready to convert to passage making mode and head out to sea, you simply lift the panels up a few inches and the two support rods slide aft as the panel is lowered down and locked into place.
Our Sparkie Hilmi always has a long list of electrical jobs that need his attention and this past week was certainly no exception. With almost 150 circuit breakers on XPM78-01 Möbius to safely look after all our 12 & 24 Volt DC circuits and our all our 120V & 240V AC circuits, it was quite the design challenge to figure out where and how to place all these.
We ended up with two primary circuit breaker panels; this one on the angled short wall on the Stbd/Right side of the Main Helm Station.
And this larger one in the Corridor at the bottom of the stairs leading down from the SuperSalon to the Guest Cabin, Ships Office and Workshop/Engine Room.
After months and months of preparation, Hilmi was finally able to bring it all together this past week by attaching these Black AL panel fronts with all the engraved labels onto the hinged access doors into each of these Circuit Breaker panels.
Next week the hinged glass doors are due to arrive which will finish off these critical component of the electrical system on Möbius.
The double paned 16mm thick glass window finally got installed in the Engine Room door this week which is a critical component to completely closing in the Engine Room in the case of a fire.
And the gas lift cylinders have now all been installed on the Glass Deck Hatches which I designed and Naval built in house. Now just need to finish installing the rubber edge seals and the AL hatch handles and the deck is totally watertight!
I can’t possibly do justice to explain the amount of work that Christine has done this past week alone on getting all our navigation and electronics in both Helm Stations all setup and working.
Nor can I articulate how much I LOVE my Captain!
What I can do though is to leave you with this shot from early this morning that does capture for me just how well we have succeeded in designing and building our new home with all of Team Möbius to meet the goal we set out over 5 years ago to blend in perfectly when in a commercial dock as apposed to a ‘yachty’ marina.
And with that I am going to hit the “Publish” button on this latest Möbius Weekly Progress Update and look forward to bringing you more Show & Tell of this coming week’s progress that begins first thing tomorrow morning.
One year ago, Christine and I returned from a brief trip over to the UK for her Birthday (March 15th) just as the whole Corona 19 pandemic was ramping up and caught us squarely in the vortex. Given our ages, let’s just say rapidly approaching 70, every day since we have been playing a kind of Russian Roulette by going into the shipyard to work on Möbius and so we are eXtremely eXcited that tomorrow morning at 11am we are going to get our Covid 19 vaccine shots!
Of course, this doesn’t put an end to anything really but sure will help with our upcoming travel plans, for which we shall be eternally grateful to this country we have called home for almost four years now and that love a wee bit more every day. Thank you Turkey for allowing these two salt water turkies to enjoy your beautiful country and people!
First and most importantly, let me send out a big Happy Valentine’s Day wish to all of you. I hope that you and those you love treat yourselves to an extra special Valentine’s Day Sunday. Christine and I have done our best to do the same though our Valentine Möbius seemed to get the majority of the TLC and attention as you’ll see below.
Before I begin this week’s Progress Update, a brief story (I promise!) that sums up our lives right now.
When I was about 8 years old, my never ending curiosity lead me to read about one of Zeno’s paradoxes that completely dumbfounded me and led to many sleepless nights trying to wrap my head around it. That paradox has been haunting me again as we get closer and closer to finishing and launching XPM78-01 Möbius so I thought you might enjoy the story. I suspect many of you know this particular paradox often referred to as Zeno’s Paradox of the Tortoise and Achilles and you too might have also found it undeniably true but equally hard to accept at first. My eight year old self read it as a simple question;
If you want to get from Point A to Point B and each step you take is exactly 1/2 the distance between you and Point B, how many steps will it take you to get there?
An infinite number of steps and you will never get all the way there! Think about it, you’ll see the paradox.
Ahhh, I see those smiles and nods of recognition and you already know why I feel like I am living that paradox every day! Step after step, progress being made as we inch closer and closer but it feels like we’ll never get there. We WILL of course and you can read all about various “solutions” or different takes on this paradox but it does nicely sum up how Christine and I are feeling at this point.
More to the point that YOU care about and why you are reading, let’s jump into this week’s Show & Tell of the many half steps that Team Möbius DID make this past week of Feb. 8-13, 2021 and did move us closer to the finish line. And my apologies in advance for likely rushing you through this week’s Show & Tell, but it has been a very long week and it is now late Sunday evening as I’m typing this up and my vivacious Valentine awaits as does our dinner so I hope you will pardon the rush job this week.
Silicone based Foul Release Bottom Paint
If you were not able to catch up to last week’s Progress Update post “The Captain & Mr. Gee get CRANKY!” it may help to go read that over before continuing as we picked up where we left off last week wtih the preparation for the application of the International InterSleek 1100SR Foul Release paint that will cover all the underwater aluminium surfaces and keep them clean and slick by not allowing any marine growth to stick.
By the end of last week, we left the bottom paint crew having finished applying all the coats of International Epoxy Primer to the freshly sanded bare AL hull surfaces and masking off the 100mm / 4” wide glossy Black Boot Strip that makes the transition between the top of the Black InterSleek and the bare aluminium hull sides above the WL.
With the top and bottom edges of this Boot Stripe all taped off with Blue Painter’s Tape, they did a quick sand of the areas that would be sprayed with the glossy Black International Perfection polyurethane paint.
It was just before 18:30 quitting time when they got to the quick and easy part of spraying on several coats of the Black Boot Stripe. It is getting lighter here as the days get longer but still needed the help of an LED work lamp to do the spraying.
They let that dry for 24 hours and then masked it off for the big job coming next; applying the InterSleek 737 “Pink” primer coats and then the Black InterSleek final coats.
For the application of the InterSleek primer and topcoats, Naval called in the Big Guns from neighboring industrial boat builder Damen as they have a whole team of people who do nothing but InterSleek on the bottoms of the many big ships that they build and launch each year.
Given its thick consistency, InterSleek requires the use of airless spray equipment so they wheeled this bad boy over under Möbius and we brought out all the cans of InterSleek 737 Pink which is a three part A+B+C mix.
Ilyas is the Manager of Damen’s InterSleek team and started mixing this 3 part mix of 737 primer.
As per its name, an airless sprayer does not use compressed air to atomize liquid finishes out the end of a spray gun. Instead it uses hydraulic principles to push liquid paint directly from a big intake pipe set into the can of 737 Pink you see here and then out a spray gun nozzle at the other end. That big black round cylinder at the top of the airless sprayer seen here wrapped in protective plastic, is a giant rubber diaphragm that pumps up and down and pumps the liquid paint out the thing black hose you can see exiting the photo on the far Right edge by the blue pail.
This is the actual spray gun at the other end of that black hose where the highly pressurized paint flows out the small nozzle on the upper Right and ……..
…….. onto the hull like this.
As a former Automotive and Autobody teacher and antique car/motorcycle restorer, I have done my fair share of traditional spray painting but this airless spraying is more like using a very well controlled fire hose!
Möbius is 24m / 78 feet long on each side and yet
…. it took Ilyas less than 15 minutes to spray on two thick coats on all that area!
And that included details such as the Rudder and prop shaft Skeg, and …..
…… the Bow Thruster Tunnel.
The 737 Pink primer was allowed to set up for 24 hours and then it was time for …….
…….. the final 3 topcoats of the Black silicone based InterSleek 1100 SR which is also a 3 part mix. All mixed up and ready to be hydraulically pumped to that big spray gun in Ilyas’ hand.
While Ilyas suited up his team mates were busy rolling the Black InterSleek 1100 on all the edges of things like the Rudder and CPP Prop Skeg.
Depth and sonar transducers……
….. and deep up inside all the 5 Sea Chest tubes.
InterSleek 1100SR all mixed up and suction pipe set inside so it is all systems GO!
Difficult to capture with the camera amongst all the fumes but that gun blasts out a cone of paint that is about 1m / 39” wide
And so once again Ilyas had the first coats of Black InterSleek all sprayed on in under 15 minutes!
It is a fascinating product which looks very wet even when it is fully dry 24 hours later and to the touch it feels “sticky” and it remains that way throughout its 5-8 year expected life. You know this feeling if you have ever handled soft silicone cooking mats or the like as that is just what is now covering all of Möbius’ bottom. Go ahead and try to stick to that you little marine munchkins!
A second coat was applied the next day and once that had dried it was time to reposition all the support stands so that the area underneath them could also receive the full silicone InterSleek treatment.
Uğur was masterful at this tricky task as he positioned a new steel stand to one side of the existing ones and then hammered in new wood wedges to take up the weight of the boat enough to remove the wedges on the other stand and take it out.
And you can see what I mean about this InterSleek stuff being slick!
With the old wedges and stand out of the way we reveal these bare AL patches whose turn it is now to get the full epoxy primer and InterSleek treatment.
These patches are carefully taped off with some special “super tape” that can manage to stick to silicone and then a roller can be used to apply the epoxy primer coats like this.
Once the epoxy primer coats were fully dry, the 737 Pink silicone primer was rolled on next.
BTW, you can see that special tape quite well here.
Finally, the last 2 coats of Black InterSleek are rolled on and our bottom is done!
The Black discs you see like this one are 25mm / 1” thick AL mounting pads with a blind threaded hole where a circular Zinc anode will eventually be attached before launch.
This is how the very aft end of the hull will look for its underwater portion.
Painting the Nogva CPP Propeller
We got mixed reviews and recommendations for using the same InterSleek 1100SR to keep the CPP propeller equally as clean and slick as the rest of the hull so we opted to go with a single purpose silicone paint propeller paint called “PellerClean” which the Japanese company SeaJet created. If you would like to know more about this product and how to apply it, Matt over on the “MJ Sailing” YouTube channel that he and Jessica maintain so well, has THIS full video on their application of PellerClean on their prop last year. If you are not already subscribed to Matt and Jessica’s MJ Sailing channel we can recommend it highly as it is one of our many favorites for great boat related content.
This propeller treatment wasn’t covered by our agreement with Naval Yachts so Christine and I looked after this application. Do I really need to answer the question about why I am so madly in love with my Valentine and perfect partner for my very imperfect self?!?
The application of these very specialized silicone paint systems is very exacting so we followed them to the letter and prepped all the bronze with a 80 grit wheel to give the upcoming PellerClean Primer a good bit of “bite”.
The 2 part yellow coloured PellerClean comes in premeasured cans which you simply stir together well for about 5 minutes and then brush on.
It is very thick with a consistency similar to mayonnaise so it is a bit challenging to get all the brush marks out in the first coat.
But with each of the successive 3 coats we were able to get it well evenly applied and then let dry for 24 hours.
The clear topcoats go on next and curiously these are a single part product and after my experience with it I suspect it is pretty much pure silicone.
Another late night at the yard for us so this is all shot in the dark with just the LED work lights which really skew the phot colors so it looks very greenish here whereas the real colour is closer to a bronzy yellow but the more important part is that this is goes on smooth and slick!
I finished the 2nd coat of clear PellerClean yesterday and I’ll see what it looks like in the morning and decide whether to add a final 3rd coat.
It was not cheap but a clean propeller and bottom makes SUCH a difference in terms of boat speed and amount of power it takes to propel the boat through the water. This was very evident to us on our previous 52 foot sailboat and so now with our XPM power boat, these super slick easy to keep clean surfaces will make a huge difference in our fuel economy and increase our speed through the water. Stay tuned for those data points once we launch and start logging real world measurements.
More “Big Little Jobs” this past week:
Apologies in advance again for blasting through this but thought you would enjoy seeing some of the “little jobs” that add up to Big things which got done this past week.
Our Super Sewer Sinan, whipped up this “skirt” that wraps around the round Anchor Chain Bin and seals the top to the Hawse Pipe where the Chain comes In/Out and keeps all the muck and mud from the anchor chain, inside the Chain Bin where it is easily rinsed out through the drain in the bottom.
I had originally thought about having Sinan put in a clear plastic window so we could see inside the Chain Bin to see how the chain was moving In/Out but instead we went with this KISSS Velcro slit which you can open up anytime and peer inside.
Sinan attached the Skirt to the outside of the top of the Chain Bin with snap fasteners so it is also quick and easy to do the Full Monty and take the whole skirt off (but you can keep your hat on!)
The cylindrical tops of these Tiller Rudder Stops were back from the machine shop with their M16 threads for the SS bolt and locking nut that provide adjustment so Uğur was able to finish welding these up and we will show you them being mounted next week.
Ramazan was busy much of this past week up in the Master Cabin and here is is fitting the FastMount fasteners for the access panel below the seat in the Master Shower. This provides full access for all the plumbing and water manifolds hidden away inside the base of the Shower Seat.
Which the Captain is particularly looking forward to and testing out here.
Just outside the Shower, Ramazan has now installed the mirrors on this cabinet above the Vanity Sink at the very forward end of the Master Cabin.
As well as these mirrors on the doors of the cabinets above the sink inside the Master Head/Bathroom.
Overhead dropped ceiling above our bed is reflected in the mirror here so you may need to look twice to figure out that this is the full length mirror that Ramazan is mounting to the inside of the Shower/Head door now laying on top of the bed.
From the outside looking in I find Ramzan up at the Main Helm taping off the Rosewood Window Sills as he installs all 21 of the HVAC air vents on all the SuperSalon windows.
We were able to track down these very well made rotating adjustable air diffusers that are made for use in many different makes of cars and trucks and are the Goldilocks solution for bringing the hot or cold air from our AC/Heating system into the SuperSalon.
Same as the ones you would be familiar with in your car, these rotate and can be closed shut as in the photo above or tilted open at different angles. This will give us full adjustment to the air coming in to direct it into the room or up onto the windows for some defroster like function.
The largest front and center window in front of the Main Helm gets 3 of these vents.
And all the other windows have 2 diffusers.
Captain Christine has jumped feet first into the deep end of the electronics systems on Möbius and had a very busy week working with things like our PepWave cellular/WiFi router which I will cover in another post focussed on all of our electronics.
We had just enough of this gorgeous Turkish Turquoise marble from our inside Galley to use in our Outdoor Galley countertops as well and that all got mounted this past week.
We didn’t have quite enough to do all the countertops in single slabs but we are SO in love with this marble that we created the tops out of several pieces.
The system I came up with started with 6mm AL plates that are through bolted to the Vent Boxes underneath and then the marble is permanently adhered to these AL plates with industrial SikaFlex.
This allows me to remove the whole countertop for future access by unbolting these AL plates and provided a super solid backing for all the marble pieces.
First slab with the cut-out for the SS sink all glued in and ready for the 2nd piece.
To be set into the SikaFlex much like how you would lay ceramic tiles.
This will give you a sense of how our Outside Galley is shaping up and next week the marble team will be in to finish sealing and polishing the tops and edges. I can smell the salmon cooking on the BBQ already!
Möbius Goes to the Dogs!
Saving a bit of the best for the last, our two dogs, 14 year old Ruby the Wonderdog in Black and 9 year old Barney The Yorkshire Terror were onboard for the first time with Captain Christine so they could check out what will soon be their new floating home too.
Like us, they have both spent most of their lives as boat dogs and so are awaiting the move onto their new boat/home as anxiously as we are.
Barney is a rather “excitable boy” who can sometimes get a wee bit too excited at the edges of our boats so the bottom Dyneema lifeline that Christine now has all finished is at a custom “Barney height” so he got to measure up to that.
And down in the Master Cabin we have what we refer to as The Barney Bed, where Mr. Actionallnightlong, will be able to sleep and practice is nightly training for the Olympics all by himself!
And THAT folks is going to have to be a wrap for tonight as I am Wayyyyyyyyy past my time limit and bedtime and dinner still awaits.
Thanks SO much for taking the time to join us here again this week and just because it is taking me much longer than I would like to answer them, PLEASE keep adding your questions and comments in the “Join the Discussion” box below.
See you here again next week as we take yet another of our infinite half steps forward.
The start of our marine based circumnavigation of this awemazing planet of ours will have to wait for a few more months but yesterday (Saturday Jan 23, 2021) marked the completion of my 68th circumnavigation of the sun and I’ve already got my 69th off to a great start.
I had a marvelous birthday yesterday by being able to do what I love most, build things with my hands, with the person I love most as well as receiving an overwhelming number of B’day best wishes from so many friends and family I am so fortunate to have in my life.
Christine and I spent the day at Naval Yachts working on our Tender and were delighted to be able to fully install our Castoldi 224 DD jet drive and Yanmar 4JH4 TE 110HP diesel inboard engine which was another great milestone for us to hit and she is now well enough done for us to load onto the Aft Deck of Möbius before we Launch. Just as we were finishing putting the Yanmar in place Dincer and Baris showed up with a delicious strawberry B’day cake which was a delightful surprise and made my day all the more special.
Team Möbius also hit several other major milestones this past week so grab your favorite beverage and comfy chair and let’s jump right into this week’s Progress Update Show & Tell.
PAINT MY BOTTOM!
Perhaps the biggest milestone this past week was the start of putting on our “bottom paint” which is the only paint there will be on Möbius as all other aluminium surfaces are being left in their beautiful Silver “raw” aluminium state for minimal maintenance and the “all business” work/commercial/military esthetic we want for the exterior of XPM78-01 Möbius.
However for the same low maintenance reasons, the situation is reversed for all the aluminium surfaces that are below the Waterline WL which will be painted with 5 coats of Epoxy Primers and then some top coasts of International InterSleek 1100SR which is a silicone based Foul Release type of Bottom Paint.
The final bit of preparation of the hull was done by Nihat who finished up with what should be the final bit of aluminium welding when he welded on the threaded attachment discs for the ten zinc anodes that will be bolted onto the hull after it is all painted.
These zinc discs are how we protect all the various dissimilar metals on Möbius which range from Stainless Steel, to Bronze to Aluminium and several others, from Galvanic Corrosion which is what occurs when two or more dissimilar metals are immersed in an electrolyte such as sea water.
Referred to as “sacrificial” anodes Zinc is one of the least “Noble” of metals and so it will ‘sacrifice’ itself by corroding first and thus protecting the other metals. As these Zincs wear away with corrosion they are easy to replace with new ones.
Zincs come in all shapes and sizes and we’ve decided to go with the more streamlined round disc shaped ones so Uğur quickly made up ten of these 80mm/” 3 diameter discs of 20mm / 3/4” thick AL and then welded them along the length of the hull.
This one will help protect the Rudder and its shaft.
BTW, the oval plate you see tacked in place near the leading edge of the Rudder is for the through hole in the Rudder which allows us to much more easily remove the prop shaft should that ever be neccessary by turning the Rudder hard over and letting the prop shaft slide through it so there is no need to remove the Rudder.
The tacked on plates covering this hole on either side allow the paint crew can cover this with Epoxy filler and create a smooth sleek shape to the Rudder for maximum performance.
Two more, one on either side, of the Keel and Prop Shaft Skeg and then six more matched pairs along the length of the hull up to just aft of the Bow Thruster tunnels at the Bow.
First order of business for the Paint Crew was to fully “tent” the bottom of the hull with plastic sheets. This is both to keep dust out from other work going on in the shipyard and keep in any overspray when they are spraying on the Bottom Paint.
The other reason for the tenting is to control the temperature and humidity of the hull which is done by this air heating system that is sealed onto the plastic tent sides.
We have been having a bit of a cold snap the past week here in Antalya with night time temps dipping down to 4C / 38F so we needed to bring the temperature of the AL hull up to < 15C / 60F for painting and filling. Getting warmer, just a few more degrees to go.
Plastic all taped down to the concrete floors to seal everything in/out and it was paint time!
Azad, standing on the Left is Naval’s Master Painter and Ali on the Right and Mehmet kneeling on the Left round out our Paint Crew who where meeting here to go over the painting application process.
You learn the hard way that it is not advisable to mix various different brands of paint so everything from the first coat of etching primer to the filler and the final InterSleek 100SR Topcoat is all from International Paints. I have had excellent success with International paint on our previous boat so I wanted to continue to “go with what you know” for critical things like Bottom Paint.
As you may recall, Ali and Mehmet had spent all last week sanding down all the AL hull surfaces to remove the AL oxide that naturally forms on raw AL and they gave it all a quick light sand, wiped it all down with acetone thinners and clean white rags and Möbius was ready to have her Bottom painted!
I prefer rolling on the primer rather than spraying as I think it improves the critical initial adhesion. All the welds will be filled and sanded so as to create a completely smooth surface for minimal resistance when slithering through the sea.
So these areas received the first coat of White InterPrime 820 which is a high performance, high build epoxy primer specifically formulated for underwater Al surfaces that will have epoxy filler applied on top.
Once all the welds and other areas that will have Epoxy filter applied were covered in the White 820 primer, Ali & Mehmet rolled on the Bronze coloured InterPrime 450 which is optimized for maximum water barrier and long term anticorrosive protection.
And in just a few hours they had all the AL underwater surfaces fully covered with their first coat of Epoxy primer.
Once they had all the AL covered with the initial coat of Epoxy primers, they could start mixing up the epoxy filler and smooth that onto all the welds to create smooth hydrodynamic surfaces for the water to flow over.
Mehmet and Ali have painted and filled a LOT of boats so they are eXtremely fast and efficient at applying this first coat of filler.
This first coat provides the majority of the filler needed to smooth out all the welds and then after it is fully hardened they will take their long boards and orbital sanders to smooth out all the surfaces and add any more filler needed to make each surface perfectly smooth. Having smooth flat and curved surfaces not only makes the hull much more slippery, it also makes it easiest for us to clean when we dive the boat every few months to wipe off any growth that has formed from sitting at anchor for long periods.
In this photo we can see two good examples of this such as the exit from the Bow Thruster tunnel and the nicely coved welds between the thick Keel Bar and the hull plates on the very bottom.
Clean water flow over the CPP propeller and the Rudder are two other eXtremely important areas so all the welds and transitions receive a good coating of filler so they can be sanded into smooth gentle curves for the final paint to go on top.
Be sure to join us here next week when the sanding, filling and primer continues.
With their work done outside the boat, Nihat and Uğur moved inside to build and install the Emergency Tiller. This is another one of those bits of kit that we hope never to use but are always glad to have just in case.
I designed the whole Tiller Arm to be eXtremely simple and eXtremely robust so you can see how the Tiller Arm itself has been machined from a single solid block of aluminium which clamps around the 127mm / 5” OD AL Rudder Shaft. We extended the top of the Rudder Shaft up above the Tiller Arm and milled a large 80mm / 3” hole in it for a 2.3m / 7.5ft thick walled AL pipe to slide into.
To help support this Emergency Tiller pipe, Uğur is bolting this 20mm / 3/4” thick AL plate to the front wings of the Tiller Arm
This provides plenty of leverage to the Emergency Tiller pipe so it can provide more than enough power to turn and hole the Rudder in position in even the most demanding of rough water conditions.
Almost finished here, just need to put some holes in those two AL tabs on the front of the Tiller pipe so that we can fasten two Dyneema block and tackle setups between the end of the Tiller and the side frames of the hull to keep the Rudder in whatever position needed and to be able to steer the boat smoothly by letting one block out and pulling the other in.
We will test it out on sea trials and then stow it hoping to never need to bring it out again, but it does help us SWAN or Sleep Well At Night knowing it is there.
Mr. Gee puts his Jackets On
Mr. Gee got some attention this past week as well when I found the time to install all of the insulation jackets covering all the SS dry stack pipes of his Halyard exhaust system. This is what his dry stack looks like when it is “naked” and with the aft two of the support braces installed.
And this is what it looks like as I started dressing him up with his class Gray insulation jackets.
As they did with the whole exhaust system, Oliver and his talented team at Halyard in the UK did a fabulous job building this set of jackets that wrap the entire dry stack portion of the eXhaust to keep the heat out of the Engine Room until it has the sea water injected into it and cool everything down as it enters that large White Silencer/Water Separator just visible on the far upper Left.
This is a stack of the little mini jackets that wrap around each connection joint of the three main jackets and ensure that no heat escapes out these joints.
The bulk of the insulation value comes from that White fluffy material you can see running the length of these inside surfaces and with a thin SS mesh sewn in to keep it all in place. Then thick canvas like material is sewn into each end of each jacket so that each joint is very tight and no air can flow in or out.
The outer jacket material is very soft and supple to your hand yet fully fireproof and adds another layer of insulation. Cords are sewn into packets along both outer edges so that you can cinch each jacket up tight where it wraps around the jacket underneath.
Double D-Rings on the center straps make it easy to wrap the jacket around the pipe and cinch them down tightly around the circumference of each pipe and pull the straps tight.
I started by wrapping the first long vertical jacket on the far Right here followed by the second short curved jacket that butts up to the vertical one around the elbow to make the transition to the long horizontal jacket I have partly fastened in place here.
With all three of the longer jackets all strapped down I now wrap one of these narrower jackets around each joint where the inner jackets meet to fully seal in all those joints. You can see the first narrow jacket fully cinched down around the end of the vertical jacket and the bottom of the elbow and I’m about to wrap the next one around the joint between the horizontal jacket and the elbow jacket.
Very much a KISSS Keep It Simple Safe & Smart system which I am very pleased with. Keeps most of the heat inside the exhaust system and out of the Engine Room, Safe to be around such hot components with little danger of grabbing or falling against such eXtremely hot parts and easy to remove to check or do maintenance. Well done Halyard!
CPP PITCH GAUGE SENDER
Hilmi also spent some time in the ER this past week installing this bronze Kobelt Pitch sensor on the Nogva CPP Gearbox.
Very similar to a Rudder angle sensor, the Bronze arm with the spacers taped onto will be connected to the lever on the Nogva that changes the Pitch of the CPP prop blades. This data is then sent out that Black cable and up to the CPP Pitch gauges at each Helm station as well as being put onto the boat data network that we can view on any screen from our phones and tablets up to the big boat monitors.
HOUSE BATTERY BANKS FINISHED
Hilmi and I also spent some time in the Basement and were able to finish the four House Battery Banks under the floors down there. Each bank consists of four FireFly Carbon Foam 4V @ 450Ah batteries wired in Series to create a 24V @ 450Ah bank. Each of these four banks are wired directly into the main DC High Amperage Distribution Panel above them.
The bottom six 4V batteries are Bank #1 located in the Aft most battery compartment which is under the floor and goes down to the very bottom of the hull along each side of the 25mm thick Keel Bar that runs the length of the boat. Each compartment is sealed in with 6mm AL floor plates and rubber gaskets.
Starting to tidy up all the wiring in Bank #2 at the bottom and #3 on top. Red/Black cables are the positive and negative cables each 250mm2 which is about 4/0 AWG size to ensure that we have no less than 2% voltage drop in any of these cables.
The Gray wires connect a variety of temperature sensors to each battery bank so we can monitor the temperature of each individual bank as well as the ambient temperature of the Battery Compartments which are vented in/out with thermostatically controlled fans. The temperature data is not only for our eyes but is also fed directly to the Victron BMV 712C Smart Shunt battery monitors which is in turn used to set the charging rates from any of the five MultiPlus Inverter/Chargers so that their battery charging is fully optimized.
Last to be worked on Bank #4 we are about to connect up the large cables and sensors gives you a less obscured view of the thick Copper positive cable take off with the T-Class fuse that the cable bolts to and the Victron battery temperature sensor under the bolt to the positive terminal of the battery.
Back up in Banks @ & 3 the cables are all now fully secured with zip ties and you can see the simple battery hold down system we came up with by cutting those shaped blocks of composite foam that wedge each battery firmly in place when the gasketed lid is bolted down.
After one last check of the BMV battery monitors and double checked all the connections, the penetration in the top center section atop all the battery compartments could be filled with special fireproof filler to fully seal the compartments and firmly hold each wire and cable in place.
Stepping back a bit to show you the lid being bolted down over Banks #2 & 3 and that now sealed penetration with all the big Red/Black cables coming out of the Battery Compartments and directly into the High Amp DC Distribution box on the upper Left. One of two 120V MultiPlus Inverter/Chargers seen on the Right, three more 240V MultiPlus’ are on the opposite side.
Möbius is now all powered up which is yet another big milestone for us.
SHOWER TEAK FLOORS ARE IN
Orkan and Ali finished building the three sections of Teak flooring for both Showers and moved them onto the boat this past week.
This is the Shower in the Guest Cabin showing off its beautiful new Teak floor. If you look closely (click to enlarge any photo) you can see how the edges are relieved with a 15mm/5/8” gap away from the walls which is here the water falls down to the shower pan below and then out the drain into the Grey Water tanks.
Each floor section is removable for cleaning and maintenance.
Same design up in the Master Head.
With a second floor panel in the connected Shower.
All coming together very nicely if I do say so myself and the combination of materials and colours are very pleasing to our eyes and seem to be able to keep up with those artfully etched glass walls.
Last bit of Teak is the permanently affixed panel that goes on top of the seat in the Master Shower to help keep you from slipping when sitting so Ali got right to work at that.
Ali and Orkan do all the Teak deck work at Naval so they too have LOTS of practice and make this all happen very quickly.
SUPERSALON SUPERING ALONG
Up in the SuperSalon, Nihat and Uğur finished mounting the Llebroc Main Helm Chair to the now finished Ado LVT vinyl floor.
In eXtreme sea conditions the forces on these pedestal bases can be high in the eXtreme so they are bolted through 60mm / 2.5” thick solid laminated blocking under the flooring and thru the Aluminium floors into 15mm thick AL reinforcement plates in the ceiling of the Basement.
I took this shot while briefly sitting in the fully mounted Helm Chair with the camera lens held at eye height to give you an idea of the view forward from the Main Helm. It is a bit cluttered up there on the Bow right now as Christine is finishing off all the Dyneema lifelines and Uğur is putting in the Dorade Cowls, but you can still see how much visibility we have when conning the boat from this Main Helm Station.
And here is one of the silicone cowls on the four Dorade boxes on the front deck. These ensure that we always have plenty of fresh air circulating in our Master Cabin even in rough breaking seas when we would not be able to have the hatches open. Ventilation on an XMP type of boat is critical for two of our four priorities; Comfort and Safety.
Each White/Red silicone cowl can also be rotated 360 degrees by just loosening that notched Gray ring at the base and then tightening it back down. Any water that gets into the cowl simply flows out those slots in the bottom of the AL Dorade Box and none can get down the 100mm / 4” AL vent pipes going down into the Master Cabin.
Uğur and I worked together to install the locking latches in the large hinged hatch in the SuperSalon that gives you access to the Basement below. Ramazon had finished laying down all the LVT vinyl flooring so we could now cut out the recesses for the two SS locking latches for lifting up and locking down this big hatch.
We were running a bit short handed so we had to call in this foreign help and he worked out so-so.
I just love my little Milwaukee 18V router and it made short work of routing out the recesses in the vinyl flooring and underlying plywood for the SS latches to fit into and be flush with the flooring.
It was a bit tricky as the recesses needed to be multiple depths for the different steps in the base of the SS latches as you can see here.
We cut out little cardboard temples you can see in these photos and used them mark out the floor and then I could carefully sneak the router up to those lines.
On the underside of the Hatch these SS levers turn to engage into slots on the frame and ensure that the hatch stays fully closed and could not fly open if we were to ever roll over.
TENDER is READY to GO ONBOARD Möbius
As I mentioned in the intro, Christine and I spent the day yesterday (Saturday Jan 23, 2021) at the shipyard as we wanted to get the Tender ready to be loaded onto the Aft Deck of Möbius just before the boat mover takes Möbius over to be launched. Uğur and Nihat had finished the hull last month and now we needed to get the jet drive installed and the Yanmar engine in place before lifting the Tender onto the Aft Deck.
Earlier in the week the Fenders we had ordered over a month ago showed up and are great to have so we can install them soon. It took a lot of searching but we finally found a Turkish company making these very industrial grade rubber fenders for bit Pilot Boats, Tugs and docks which were just what we were looking for.
If you look closely in the rendering above you can see how we have designed these fenders to wrap all around the upper edge of the hull which will enable us to easily rub up against rough docks and concrete walls as well as use the Tender as we intend to as a “tug” for moving Möbius around or helping out other boats.
Not sure when I will have time to install these but I’ll show you when it does happen.
I will likely install a row of these on the stern of Möbius as well so we would be able to similarly push up against a rough concrete wall with no damage or concerns.
We started by disassembling my hydraulic hoist up in my workshop at Naval and moved it down to the shipyard so we could use it to lift our Castoldi 224 DD jet drive and Yanmar 4JH4 TE 110HP diesel inboard engine into the Tender.
I designed the hinged lid on top of the Engine Bay in the Tender so it would go well over center when fully raised but we tied it on just to be safe as we had to lift the Tender up quite a bit to be able to get the jet drive in from underneath.
Always great to have a fully rigid and solid aluminium boat hull and so it was a piece of cake to wrap a length of webbing around the Swim Platform and attach the end of the hoist to this to life the whole aft end of the Tender off the floor. This hoist is just SO handy to have and I’ll be taking it with us when we go as it all comes apart and stores very small.
Equally handy and coming with us are these jack stands which I’ve had for probably 30+ years and worked just fine to prop the Tender up above the floor so we could slide the Castoldi jet drive home from underneath.
We had done a dry fit of the Jet Drive into the Tender when we were building the hull and then stored it, upside down here, it the wood crate it had been shipped in. Now it was time to flip him over and get him permanently installed and sealed into the hull.
”Are you SURE you know what you’re doing?!” asked the Captain which is not a new phrase from her as you might imagine.
Yet another super handy tool is my little car floor jack and it worked well to balance the Jet Drive on and then jack up into the Castoldi supplied AL frame that had been welded into the bottom of the hull.
We first did one last dry fit just to make doubly sure that all the holes I had drilled in the thick transom plate and the bottom flange in the hull and then lowered it back down to clean all the mating surfaces with Acetone.
Then squeezed on a good bead of Sikaflex 291i structural adhesive on all the mating surfaces.
Then slide it home one last time and insert the SS bolts
and torque them all down.
With the Jet Drive now all bolted in place we could now install the two cylinders on either side. Port/Left side is the cylinder that moves the jet nozzle and steers the boat.
Starboard/Right cylinder moves this bucket that sits overtop of the flow of water coming out of the jet and redirects in whatever direction you wish to go forward, reverse or sideways.
The whole installation went very smoothly and the Jet Drive was now fully in place.
Next up………….. unboxing and installing our four cylinder Yanmar 4JH4 TE 110HP diesel inboard engine that has never even been out of the box he shipped in.
After some initial concerns that the motor in our Tender would be three times more powerful than the Yanmar in her last 33’ Caliber sailboat, the Captain seems to be warming to the driving force in our Tender.
It took some work to find the model I wanted which s this one with all direct mechanical fuel injection rather than ECU controlled common rail but thanks to the super helpful Yanmar dealer at Denpar Marine here, this is just what I wanted.
I have used this same hoist to lift all of Mr. Gee’s 1200Kg / 2650 lbs many times during his full factory rebuild so lifting the mere 217Kg/ 478lb Yanmar was a piece of cake.
We rolled the Yanmar around to the Stbd side and then under the hull and it dropped right onto the 25mm / 1” thick AL engine beds welded into the hull.
The Yanmar has landed!
With so many other priorities on our plates this will be good enough for now to just have the Yanmar sitting on the Engine Beds and I’ll get back to bolting the motor mounts in properly later.
This engine and jet drive are a matched pair that Castoldi put together so it came as a very complete system that I am very pleased with.
This is a Direct Drive jet drive so there is a short cardon shaft (drive shaft) that connects the output shaft from the Yanmar to the input of the Castoldi which makes alignment and connection all very simple and this is all work that I can do after we launch and have the Tender on the Aft Deck of Möbius.
But for now, this closes the door on our Tender and she is now all ready for the crane to lift it onto the Aft Deck of Möbius just before the boat mover shows up to carry Möbius over to the harbour and LAUNCH!!!
Can’t let myself be distracted by that excitement yet as there is still SO MUCH to do before she is ready to launch but there is definitely light at the end of this looooooong and winding tunnel!
So do stay tuned for the big finale folks, it IS getting closer and closer and we would be delighted to take you along with us over the finish line! I’m sure that many of you are feeling like this journey would never end and we sincerely thank you for sticking with us and for all your contributions of questions and suggestions that have been so helpful along the way and PLEASE do keep them coming by typing them into the “Join the Discussion” box below and I look forward to seeing you here again next week.
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.
You 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.
We 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.
Directly 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.
This 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.
There 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.
As 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”.
In 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.
Hilmi 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.
Such as these Green Navigation Lights that Hilmi is checking out here on the Starboard/Right side of the SkyBridge coaming.
Red 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.
Christine 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.
Similar 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.
This 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.
We 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.
Just 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.
In 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!
By 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.
As is this small area around the Lewmar EST65 Warping/Kedging winch.
OTHER ELECTRICAL JOBS
Our 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.
Finished 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.
Std Horizon GX6000 VHF-AIS top center with the External Light Switch panel below which we saw earlier.
Right of the VHF is the Vetus Bow Thruster joystick and the Furuno NAVPilot 711C below it. Maxwell anchor windlass control upper Right with Kobelt 7170 Jog Lever below. Round gauge on far upper Right is the Pitch angle of the CPP propeller and hiding under the plastic is the Kobelt 6501 electronic control head for the Gardner Throttle and Nogva CPP Pitch adjustment levers.
Looking 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.
Here 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,
In 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
Yesterday (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.
Hilmi 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.
Before 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.
Right 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.
Along 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.
Down 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.
Christine 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.
Simple eye splice where each Lifeline begins with this “Luggage Tag” style attachment to the 40mm/1.6” thick walled AL stanchion posts.
The 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.
Where 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.
For 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.
Along 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!
Ramazan 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.
Here 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.
A 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.
Main 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.
Flooring all done in the Galley now.
With 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.
Plywood 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!
You 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.
Here is where we left off last Weekly Update with the front and rear rails or “staples” that Uğur and Nihat had installed.
On 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.
Second 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.
Cihan 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.
I 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.
Here 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.
Two 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.
I 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.
The 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.
Her 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!
Another 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.
On 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.
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:
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.
It 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.
Next 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.
The 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.
So 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
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.
The 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.
Another 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.
Looking 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.
Instead 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.
A 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.
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.
I 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!
Non-Slip up on Top:
Just 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.
We 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!
We 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.
Faruk 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.
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!
Last week you may recall seeing Ramazan finish installing the ADO vinyl LVT flooring in the Master Cabin and he has that now all finished.
Keeping 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.
His 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.
Master 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.
First 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.
After checking that each plywood floor panel was solidly screwed down, Ramazan stared to do his layout for the floor planks.
Starting with this reference line for laying down each row of planks perfectly parallel to the centerline of the boat.
Click – Click, assemble one row of planks.
Click – Click, lock that row into the previous one laid down.
Rinse and Repeat, with lots of careful scribing and fitting around all the radiused Rosewood toe kicks surrounding all the cabinetry.
Screens, Screens and more Screens!
Winding 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?
It has something to do with these two unfilled spaces front and center at the Main Helm.
That’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.
The 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.
Both 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.
Another 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.
Didn’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.
First 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.
They 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.
These 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.
As 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.
When 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.
Speaking 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.
Each 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.
That 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?
Keeping 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.
I 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.
Same 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.
We then test fit them in place on Mr. Gee and once tweaked into just the right fit Uğur welds the slots closed.
As 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.
Uğur could now weld on the 20mm / 3/4” thick base plates and weld all the bend slots closed.
Nihat picks up with his angle grinder and quickly cleans up all the welds to create smooth soft curves.
That 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!
Our 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.
This 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.
Up 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.
Inside 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.
My 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.
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.
The 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.
There 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.
Super 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.
In 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.
