I double checked the calendar and it is indeed just the beginning of May but it sure feels like summer here in Antalya today. We’ve been having fabulous weather all year actually with an eXtremely mild Winter season that saw very little rain and very mild temperatures. But Spring has been off the charts in terns of great temperatures, low humidity and no rain. Today, Sunday May 9th, is a real scorcher and as I sit and type this aboard Möbius at 14:00 the temperature is a toasty 34C / 93F with a little bit of wind and crystal clear skies. No complaints from any of the crew aboard the good ship Möbius, that’s for sure.
While the lack of visual progress to show you continues as we work our way through the final jobs remaining to fully configure and test all the many systems onboard XPM78-01 Möbius, the amount of work required to play this real world version of Whack-A-Mole is relentless and non stop. That combination conspired to prevent me from putting together an update for you last week and I thank all of you who wrote to ask if all was well and thank all of you for your patience. In this Progress Update I’m going to combine the past 2 weeks into this one, so please grab a comfy chair and beverage and join me for a Show & Tell of what’s been happening from April 26th through May 5th, 2021.
All Hands on Deck!
In addition to all the configuration and testing, there is also a long list of those “little jobs” that add up to be quite a large amount of work all together and we knocked off more of these the past 2 weeks as well and here are a few examples.
Here we find Captain Christine, ably abetted by our two four legged crewmembers, Barney (Left) and Ruby, finished whipping the Dyneema lifelines she had previously spliced in place and which are working out eXtremely well.
The Rosewood Dinette table came back from being refinished and is once again mounted to the vertically adjustable pedestal with the XY sliders that allow us to move the table 200mm / 8” fore/aft and side to side which enables us to always have the table in its Goldilocks position for any situation.
There had been some small depressions on the top surface of the table which while minor, were also very visible and took away from the otherwise superb finish on all the woodwork so the Finishing crew quickly refinished it and as you can see it is now flawless.
There are a LOT of valves, circuit breakers, hoses, electrical connections, etc. that number in the hundreds and so labeling everything is a must and makes it easy to know what’s what and how to operate all these systems. These 3 fuel manifolds provide a good example.
You may recall a few weeks ago that the two cleats on the Swim Step were upgraded from AL pipe to solid and the heat from welding those in required that the TreadMaster be removed and now it has been replaced.
The light Grey TreadMaster is also proving to be as good or better than we had hoped. The top priority is to provide a great non-skid surface in any conditions and the tight sharp diamond pattern of the TreadMaster eXcels in this department and locks even bare wet feet in place everywhere.
Second priority is to provide a more bare feet friendly surface especially when in hot sunny climates so that you don’t have to do your “walking over red hot coals” fire dance when you are on deck. While not comparable to the tropics, today’s high temperatures and intense direct overhead sunlight gives us a reasonable test and we are happy with the results.
For a baseline, as of a few minutes ago, 14:30 Sunday May 9th, here is the temperature on the fully shaded Aft Deck area which my trusty IR temperature gun clocked at 32.4C / 90F.
And out on the Stbd side decks that have been getting the most direct sun right now, the TreadMaster is at about 50.5C / 122.9F. Definately not cold, but I can stand in place on these decks without too much discomfort and when walking it is quite comfortable. As in life, everything is relative right and compared to our previous boats, with painted on non-skid on both fiberglass and steel decks, this is a HUGE improvement, so we’re happy with these results.
Love Thy Dock Neighbor!
You’ve seen in previous postings that we have some very interesting and varied dock neighbors here in the Antalya Free Zone with over 30 different boat builders producing a wild and wide range of boat sizes and purposes. Most of these boats are in a similar situation as we are, brand new being launched for the first time so that all the in-the-water testing and finishing can be done. Then once finished, they are off to their new home bases scattered around the world so boats are leaving and new ones arriving on almost a daily basis. Here are some recent examples of our recent neighbors:
On our Port side we have this 34m/112ft steel “Phi Phantom”. This is a support boat for a much larger superyacht so this is all function with huge flat decks and even larger bays below with that monster articulated crane to get all the “toys” off/on this boat and the superyacht. They also carry all the fuel, supplies, parts and maintenance crew.
These kinds of support boats are often called “over the horizon tenders” as that’s where they are to stay out of sight of the high paying passengers on the superyacht or a “phantom boat” such as this one that is to stay similarly ghost like or invisible to the superyacht it supports.
On our Starboard side we have this Bering 77 I showed you a bit in my last posting.
At 77 feet long overall, she is 1 ft shorter than Möbius but otherwise MUCH larger at more than twice our weight, much taller, much wider and quite a bit slower than Möbius (8 kts vs 11) but still a Goldilocks boat for the right owner and use case.
Down the dock a few more meters is this little fella who showed up last week and is the basis of my “Love thy neighbor” heading for this section.
Why you ask? Look a little closer at some of her deck hardware ………..
Like here for example.
Or zoom in a bit closer to read that red safety lock…..
The more you look, the more interesting it gets. For example, when those hatches in front of the two rocket launchers are opened up it reveals a relatively typical set of instruments, controls and a small bench seat for the operator.
Most of the time though and during testing, these hatches remain tightly closed and fully waterproof. So how do they operate the boat now and where is the Captain sitting?
Inside here! Turns out this is a fully autonomous vessel or unmanned drone and the real “Captain” is actually sitting …….
“ULAQ” is the first indigenous armed unmanned surface vessel (AUSV) developed in Turkey. It is being offered by Ares Shipyard and Meteksan Defence Systems to the Turkish Navy and you can read all about this fascinating research project HERE and HERE if you’d like to know more details.
Suffice it to say that we treat all our dock mates with great respect and kindness!
Get the Lead
Out no IN!
This was one of the more interesting things happening with our Bering 77 dock mates this past week.
Can you guess what they are up to and what’s in all those wood crates up on the dock?
Is this a Turkish version of a Swill Alps horn?
Nope, just an ingenious way of putting the lead ballast into the stern compartments of the Bering 77.
Here is what is inside all those crates, 1000 Kg of 5mm diameter lead balls like this.
One scoop at a time the little lead balls are poured into this funnel, run down the long black PVC pipe into the holds in the aft end and are then capped off with an aluminium plate that is bolted down overtop.
However, hands down, THE most exciting and interesting thing that happened on the docks this past week happened to us and Möbius.
Hmmmm, what do you think that crane truck is doing behind us?
And what is Captain Christine busy with and what are those weird shaped teak blocks on the Aft Deck?
Aha! That’s our Tender flying through the air!
and about to be lowered onto those Teak chocks on the Aft Deck.
……. and this.
And she fits like the proverbial glove and just as I had laid out in the 3D models; with the front Stbd fender just able to rub up against the vertical support bar coming up out of the Port Vent box……..
……… and the Aft Port corner of the fender right up against the doghouse over the stairs from the Swim Platform into the Workshop.
And there she is! Our Tender finally setting in her new home and Möbius is now fully equipped.
Sinan, our upholstery master made this tight fitting cover out of some waterproof Sunbrella fabric we had brought over from the US.
This shot provides a good perspective of how nicely everything fits and works together on the Aft Deck with the Tender onboard. Plenty of room in the Outside Galley and the entire Stbd side to walk back and forth the whole length of the boat.
Here’s what it all looks like viewed looking forward. Next up is fitting all the rigging to raise/lower the Davit Arch and the Tender within it but that should be a relatively straightforward job that can wait for now.
Oh, and we’ve settled on a name for Möbius’ new “baby” and she will be called “Mobli”. A lot of different parts to the story behind this including a reference to Mowgli in Kipling’s Jungle Book as well as being our sense that Mogli is the diminutive version of Möbius.
Welcome to our family Mogli! We can’t wait to start playing with you in the water and showing you the awemazing aquatic world that surrounds us.
Hope you enjoyed this combined 2 weeks worth of Show & Tell from all of us here on Team Möbius. We’ll be back with more next week as we inch closer and closer to leaving the Free Zone and returning to our lives sailing the world.
Not as much for this week’s Show & Tell as the Commissioning Phase is now underway which mostly involves setting up and testing all the many systems onboard which doesn’t yield much visual interest. It is not too much of a stretch to say that the systems on an eXtreme eXploration Passage Maker like XPM78-01 Möbius are similar to what a floating village would require. Given the eXtremely remote locations we favor we often have no support systems ashore or when on passage and so we need to be completely self sufficient with what we have onboard. For example we need to be able to do all of the following for an indefinite amount of time and be our own:
- Power Plant to generate all our electrical power; 12 & 24V DC and 120 & 240V AC
- Water Utility able to create and store all our own Domestic Fresh Water and Domestic Hot Water
- Sewage Treatment Plant able to pipe and store all Black Water (sewage)
- Grey Water Treatment Plant able to pipe and store (drainage from all showers & sinks)
- Telecom Utility looking after all our own cellular, WiFi and satellite communications.
- Weather Station maintaining up to date and highly accurate weather at all times is a BIG factor in keeping us safe, knowing where to be and more importantly where NOT to be at any given time and what anchorage is best for any given day’s weather.
- Navigation System allowing us to know in great detail what is all around us both above and below the waterline in order to plot our routes safely.
- Full Repair Shop. Christine and I are the only two people on board and so if something breaks or needs fixing or maintaining, as we often say “If these four hands don’t or can’t do it; it doesn’t get done. So we need both all the knowledge, skills and tools to fix every system and every piece of equipment onboard.
- Equipment & Supply Store. We need to carry any and all parts and supplies that are needed to service and maintain all these systems and again, if it isn’t onboard, it doesn’t exist in our world.
I could go on for some time but you get the idea. The Commissioning Phase we are now in is all about getting all the components in all those systems up and running and getting them all adjusted so they work correctly and together. So while there isn’t as much to show and tell you about this week, there is a LOT of things going on in this critical phase. So without any further delay, come along for this week’s update for the week of March 15-20, 2021.
One important announcement before we begin.
We had an eXtremely eXciting start to this week when Captain Christine began her next circumnavigation of the Sun. I won’t give away the number of her new circumnavigation, let’s just say that the two digits add up to Lucky 13! We are sleeping on the boat now so I was able to have her wake up to this little surprise on Monday morning.
Möbius on the Move!
For a boat that is still experiencing a number of “installation issues” that are preventing Möbius from being able to move under her own power, we have sure been doing a lot of moving!
I’ve grabbed this shot from Google Earth to help show our different locations over the past few weeks.
Position #1 is where we have spent the most time on the End Dock Wall. #2 is where we were sandwiched between the Green and Red/White boats on the Side Dock Wall and #3 is where we are now on the outside wall of Setur Marina.
As you may recall from last week’s post our first move was to be towed off Position #1 on the end wall of the harbour over to #2 on the side wall between the big Green Monster and the Red/White power cat.
This was our new view looking off our bow to the now empty end wall where we had been at position #1 for the past 2 weeks.
The reason for that move was because the little guy on the Right here was coming in to dock and get loaded up.
As you can see there was barely enough dock space for our two little Red tugs, let alone us or any other boats.
After loading that ship up he left and we were able to move back over to the end wall.
One of the small harbour tugs came and hip tied himself to our Port side and quickly moved us back to the end wall again.
That lasted until late afternoon on Thursday when we suddenly got the call that they needed to move us again because another long cargo ship was on its way in to dock on the end wall.
If you look closely at the photo above (click to enlarge any photo), you will see that a new Coast Guard boat was now in our previous spot #2 between the Green and Red/White boats and so the only option was for them to move us over to Setur Marina which is only a few hundred meters away.
With the help of the marina staff we Med Moored to this new dock #3 at the marina using two of the marina’s lines to our bow and then lines off both stern quarters to the dock.
This is where I am typing this post right now and while our stay is temporary, Christine and I have been enjoying this first sight of Möbius tugging at her dock lines with Mother Ocean just off our bow and calling our name eXtremely loudly!
Ramazan and I were able to get several of the remaining cabinetry jobs done in the Super Salon this past week. He pulled out this back wall behind the 43” monitor on the far Right/Stbd side of the Main Helm and cut the slots for the return air to the Stbd Air Handler.
It is a bit of a shame that this beautiful Ro$ewood panel will rarely be seen as it is hidden by the 43” monitor that is mounted here but it makes us smile every time we do. Simple and effective, these slots allow air to flow through them into the space behind where the Stbd side Air Handler lives and delivers either chilled air on AC or hot air in Heat mode to this side of the Salon.
While Ramazan putting in those slots, I lent a hand to work on mounting the Dinette table which is a job I have been longing to do for months now.
This is the air assist pedestal and the XY slider setup from Zwaardvis that I have shown you below and now it was finally time to mount the table to it.
This ingenious bit of hardware allows us to move the table 200mm/8” fore/aft and side to side enabling us to always have the Goldilocks Just Right position for the table.
To reference the mounting I lowered the pedestal to put the table in “Bed” position and then moved the X and Y sliders underneath to allow movement in all 4 axis.
I marked the slots on the feet of each slider with black pen as you can see here and I laid out two different positions; Passage Mode and Anchor Mode.
To allow me to move between these two modes I installed these threaded metal inserts which gives me metal M6 threads to fasten the table to the XY slider.
Fun Fact: I have had this set of threaded inserts for almost 40 years as I first used them when I was building bunk beds and other furniture before my 2 children were born!
I used a Forstner drill bit to carefully drill the flat bottom pilot holes and then you just install each metal insert with a hex socket to drive the external threads into the sides of the wooden holes.
Et Voila! 16 metal inserts with M6 threads in them all ready to accept the SS M6 bolts I will use to mount the table to the XY Slider and Pedestal.
You can see how this works now and I have also mounted the Black handle that unlocks the table and allows you to slide it wherever you want it to be.
Here is the final result, this being in Anchor Mode dinning table position.
From here you can move the table down and out in both directions to be in “Coffee Table” mode or all the way down into Bed mode or anywhere in between.
With so much more Commissioning work to be done I quickly covered it all in protective cardboard and painters tape for now.
As you can imagine, we can’t wait to remove all of these protective coverings throughout our beloved Möbius and convert from the current construction zone mode to Beautiful Living mode!
Pole Dancing Anyone?
Nihat was back onboard for a bit this week and he installed what should be the last of the aluminium components on the SkyBridge which is this 40mm/1/5” AL pipe that does 2 important jobs; a wire chase to bring some of the cables for GPS and cameras mounted on the Roof down into the Upper Helm Station and …..
……. a hand hold when standing and walking up in the open area of the SkyBridge.
This adds a 3rd pole onboard for the Captain to use in her Yoga Pole Dancing routines!
And that’s a wrap for this week and I need to get back to trouble shooting some of the gremlins that have been creeping up with our steering, throttle and CPP Pitch angle controls.
Thanks for taking the time to join in the journey and hope you’ll be back for more again next week.
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.
Not as much progress as we would have wanted to report this week as many of Team Möbius were MIA working on other boats at Naval Yachts and also prepping one of the boats beside us for its Owner’s visit tomorrow.
However, that didn’t stop the rest of us from making good progress and we achieved several big milestones that we are very eXcited to share with you now. So get a good beverage and comfy chair of your choice and come along for this week’s Möbius.World Show & Tell.
The Captain & Mr. Gee Get Cranky!
Several years ago, when I was answering some of Christine’s typically probing questions about why Mr. Gee our Gardner 6LXB was the Goldilocks Just Right, Just for us Choice for the main (and only) engine in XPM78-01 Möbius, Christine likes to say “You had me at Hand Cranked”.
This is in reference to me mentioning that one of the Gardner’s many eXtremely appealing features is that they could be fitted with this Chain Hand Crank option.
As you can see, this kind of “crankiness” makes my Captain eXtremely happy which makes me eXXtremely happy!
Very KISSS Keep It Simple Smart Safe as you can see with a rod running along the top of of the engine with handles at both ends with an Upper Chainwheel that transfers the crank’s rotation via a Chain down to a Lower Chainwheel keyed onto the engines crankshaft.
Michael and his team at Gardner Marine Diesel or GMD in Canterbury England were able to salvage all these parts off one of the many 6LXB’s they have in their inventory and sent them to me many months ago and I’ve been working on fitting them to Mr. Gee ever since.
You would think it would be a relatively quick and simple process to just clean and paint all these parts and install them on Mr. Gee …………………… but you’d be wrong!
One problem was that Mr. Gee is one of the later models of 6LXB and it had this quite different Hand Crank with just one handle on the front of the engine and a different crankshaft and Chainwheel setup down on the new style crankshaft.
Secondly, as you can see in this shot of the front support and Upper Chainwheel I’ve mounted onto Mr. Gee, there is no room up front for the Hand Crank handle, let alone enough room for me to get in there to crank it. So I needed to come up with a “Hybrid” Hand Crank setup that would allow me to marry the Old style with the Hand Crank Handle at the rear, to the new crankshaft end up front.
And just to put a particularly sharp point on this challenge, I also needed to drive the Jabsco Sea Water pump and one of our monster 250 Amp @24V Electrodyne alternators off the front of the crankshaft as well.
Let’s just say that the front of Mr. Gee became a very busy and challenging spot for me to sort out.
When I am doing this kind of problem solving and exploration of new design ideas I have evolved to using pieces of stiff cardboard I cut up from shipping boxes to capture the critical dimensions and sketch out my rough ideas.
It is a surprisingly efficient system as I get to reuse the many cardboard boxes all our hundreds of shipments come in and the stiffness of the cardboard makes is very easy to sketch on when I’m laying under or over an engine for example with my digital Vernier calipers or tape measure in hand and recording all the critical dimensions.
I then use Microsoft Office Lens utility on my Pixel4XL phone to digitize these sketches so I have a more permanent digital copy to keep and one I can print out if needed.
I don’t expect these to make much sense to anyone else but they work eXtremely well for me to record all these details and dimensions as I work my way through the different ways I come up with to solve a particular problem, create 3D models of them and ultimately machine or fabricate the parts I need and finally get them installed.
After much head scratching and sketching, eventually this layout emerged as a way that I could fit both the RED Chain based Hand Crank system and the GREEN cogged timing belt system for driving the Electrodyne “Big Red #1” in the upper Right here and the Jabsco sea water pump on the far Left.
I will show you the Green cogged timing belt drive system next week and show you the Red chain based Hand Crank system now.
With all the dimensions and my ideas roughed out on cardboard I then move over to Autodesk Fusion 360 to create a 3D model of all these parts where I can put my ideas to the test and see if they will actually work out. This is a quick screen grab of the model I came up with from the sketches you saw above.
I won’t bore you with all the details but for orientation Mr. Gee is mostly off the screen on the far Right and the Red disk is the Lower Chainwheel on Mr. Gee’s Crankshaft running horizontally across the bottom of the screen. On the front side of this is the cogged pulley driving the rubber timing belt that goes up to the cogged wheel on the Jabsco sea water pump.
* Note: I didn’t bother to model the actual chain and sprocket teeth so you will have to imagine that being wrapped around the Red Chainwheel.
The Green and Blue disks on either side of the Red Chainwheel are two of several flanged parts I needed to machine for my Hybrid Old/New Gardner Hand Crank system.
Oh, and did I mention that the Old Gardner Hand Crank system used a different pitch of chain than the New style?
So I had GMD send me the Upper and Lower Chainwheels from the New style that would fit nicely on the New style of Crankshaft that Mr. Gee has but the third Idler Chainwheel (part #37 in the Gardner illustration up above) had to the the Old style Chain as it is part of the cast aluminium bracket that supports the Old style cranking shaft.
FYI: Eventually I will design and machine a whole new Idler Chainwheel with the New style Chain pitch but for now I just mounted the Old Idler in my drill press and hand milled the teeth to get the New Chain to fit as you see here.
This is that Blue coloured Flange I pointed out AL in the rendering of the 3D Fusion 360 model above, which was quit easy to machine on a lathe out of solid aluminium round stock and then broach the keyway through the inner hole so it will be locked into the 3/8 x 3/8” key on the front end of the Crankshaft.
Now you can see how this newly machined AL Flange slides into the New style Lower Chainwheel which is now all sand blasted clean and painted Black.
All well and good but I’m sure that most of you are now asking “How the heck does this work to turn Mr. Gee’s Crankshaft Wayne?
That’s the job of the eXtra part you see here that rotates on a pin sticking out of the Chainwheel. This little part is the key to making the Hand Crank work and is called a “Ratcheting Pawl” part #3 in the Gardner Illustration above.
I don’t have a milling machine (yet!), but to badly reuse The Treasure of the Sierra Madre, (for those of you old enough to remember) “We don’t need no stinkin’ milling machine” right?
Nothing that a bit of ingenuity and my handy dandy 45 year old drill press and shiny new vice can’t handle. I machined a short shaft to just fit inside the hole of AL bushing and tightened that in the vice jaws.
This allowed me to slowly rotate the AL bushing into the 4 flute spiral milling cutter in my drill press so I could mill away the four recesses for the Pawl to fit into and ended up looking like this.
So to Hand Crank Mr. Gee you simply reach down and rotate the Pawl counter clockwise so it engages in one of the four recesses like this.
Now when Christine turns that Hand Crank Handle on the Aft end of Mr. Gee as you see her doing in the opening photo, the Upper Chainwheel rotates the Chain CCW, which transfers that force down to the Lower Chainwheel which the Pawl has now locked to the Crankshaft and around goes Mr. Gee!
This takes a good bit of muscle but with the compression relief levers keeping the intake valves open it isn’t too difficult to bring Mr. Gee’s massive flywheel up to speed and then you flip the compression levers back off and Mr. Gee chugs to life and begins to purrrrrr. Doesn’t get too much more KISSS or reliable than that!
Oh, and for those of you following all this, as Mr. Gee starts up you no longer need to turn the Hand Crank Handle and so the Pawl “ratchets” out of the recess back to this disengaged position such that the Chainwheel is now stationary while the AL Flange and Crankshaft spin together.
To finish putting this all together, I machined a groove into the AL bushing for this spring steel circlip to fit into which keeps the Chainwheel aligned and spinning on the AL bushing.
With the Lower Chainwheel assembled onto its new AL Flange, into the Engine Room I go and with a bit of TefGel 45 to help it slides just perfectly onto the keyed portion of the front end of the Crankshaft.
That modified Idler Chainwheel is in the upper Right here and it adjusts sideways in the slot you can see to the right of the Chain which you tighten down to keep the Chain Just Right Tight.
Not much space in here so a bit difficult to photograph but hopefully you can now see how the whole Chain driven Hand Crank system works.
And to come full circle, you now understand what put that great grin on my Beautiful Bride and Captain.
While we were cranking away on Mr. Gee, Hilmi and Ramazan were cranking away up in the SuperSalon so let’s go see what they have been up to this past week.
Ramazan has finished installing all the Ado LVT vinyl plank flooring and you may recall that Uğur, Nihat and I installed these two SS locking lift handles in the large hatch to access the Basement that is under the whole of the SuperSalon floor.
Most of Ramazan’s masterfully laid down flooring is covered in protective cardboard but you can see how nicely he has fit the edges around the hatch so they are barely visible.
But what’s that I see over on the far Left here?
Aha! Our 50” Samsung 4K SmarTV has arrived and will soon be mounted on a fully adjustable mounting system that fits into the recess in the now opened hinged and slotted Rosewood door.
But who’s that hiding behind that door?
Of course! Hilmi and Christine are busy finishing up all the wiring for AC, DC, Ethernet and N2K that runs inside the large space behind the TV.
This is also where our Boat Computer #1 will reside and Christine is anxious to start connecting it up and getting all our display screens up and running next week.
While she waits for Hilmi to finish the wiring behind the 50” TV, Christine fired up Boat Computer #2 and started setting things up in the SkyBridge Helm Station.
In the midst of all this, Sinan was back this week to start sewing up the Sunbrella covers like this one for that Upper Helm Station. He is also making a similar cover for the Upper Helm Chair and I will show you that next week.
Not a lot of progress on the Bottom Paint this week but they did get started on the 100mm / 4” Black Boot Stripe that makes the transition between the bare aluminium hull sides and the InterSleek 1100SR silicone Foul Release bottom paint which I have marked off for the painters here.
The International Epoxy primer has now been on longer than the maximum recoat time so they needed to do a light sanding so that the International Perfection Polyurethane paint will adhere well.
The laser level makes is SO must faster and easier to mark out perfectly straight and level lines for the masking tape to follow.
Next week the paint crew will hopefully be on site to spray on the Black Boot Stripe and then once it is dry they can mask it off and start applying the InterSleek Foul Release Bottom Paint. Hope to be able to show you all that next week as well.
All Donations Gratefully Received!
Why is THAT truck parking beside Möbius??
Yup! I’ve saved two of our bigger milestones for the end of this week’s Show & Tell. That’s a diesel fuel truck and Cihan is about to bring the very first drops of diesel fuel into our six integral fuel tanks!
It took a lot of time but I think we came up with an eXtremely effective design for both the Fuel Fills and Vents on Möbius.
With the fully sealed lid removed you have ready access to these three Fill Pipes on the Starboard/Right side and a matching set on the Port/Left side. These each connect to one of the six integral fuel tanks at the bottom of the hull with 40mm / 1 5/8” ID rubber fuel hose.
Just forward of the Fuel Fills, these inverted 40mm U pipes are similarly connected by that same size rubber fuel hose to the vents on each fuel tank. Together these both worked just perfect on this first fueling test with no foaming or “spit back”.
But mistakes can and will happen so we designed these Fuel Fill stations to have a large capacity spill tanks below the Fill Pipes so that any diesel that does overflow will simply run into this spill tank and drain back into the fuel tank. No mess, no fuss, no bother.
When the Fuel Fill cover is in place it completely seals off all the Fill Tubes from the outside air and from any sea water on decks. The Fuel Vent pipes have this slotted cover so they stay well vented and there is a drain pipe inside to remove any seawater that might make its way through the slots.
For this first load of diesel, we only took on enough fuel to do all the commissioning of diesel based equipment such as the Kabola KB45 boiler, all the fuel transfer pumps, Alfa Laval fuel centrifuge, fuel polishing system and Mr. Gee of course and then enough for the first set of sea trials.
Hence, we only took on a “measly” 2150 Liters / 567 USG out of the 14,600 Liters / 3860 USG that we will take on prior to our first passage. However, as per the intro, all donations are still very much welcomed!
X marks the Spot!
OK, are you ready for the final milestone that Christine and I just completed yesterday?
Does this help you guess what we are up to?
Helpful hint: It took place UP here.
That’s right! Time to apply these CNC cut vinyl letters and numbers to put the XPM78-01 markings big and bold on Möbius’ Bow.
All pretty simple to do. First mark off the top edge of the lettering with a straight edge and pencil.
Give the area a good cleaning with 3M Scotch Brite pads and water, rinse well and then sponge on a coat of clean water with lots of liquid dish soap in it so you can slide the lettering as needed to get it perfectly aligned.
Peel off the inside layer of the peel & stick lettering and press it onto the soapy wet hull and use your fingers and a plastic spreader to squeeze out all the water and get all the letters and numbers perfectly aligned and adhered to the hull.
Then carefully peel off the outer layer and go over each letter with lots of pressure on soapy fingers and plastic scrapers taking special care to ensure that all edges are tightly bonded to the hull and there are no bubbles or wrinkles.
Bring in some cheap labour if you must.
Take your time to go over each letter and number several times.
Then stand back to check out the proportions and placement.
And yes, we would be delighted to be mistaken for a military/coastguard ship in the unlikely event that anyone is considering approaching us with mal intent!
Now THAT is a Bow to be proud of!
And that’s a wrap for the week that was February 01-06, 2021.
Thank you all SO much for taking the time to join us here and we hope you will be back again next week. In the interim please be sure to put your questions and comments in the “Join the Discussion” box below.
As Launch Date looms larger and sooner the theme of checking off all the “little Big” jobs on the punch list continues although we still have a few “Big” jobs such as painting the bottom with foul release paint which continued as well this past week so without any further ado let’s jump right in to see all those jobs both little and BIG that Team Möbius looked after this week of January 25-30, 2021.
One of the “little Big” jobs that we completed this past week is getting the propeller shaft fully aligned with the output flange on the Nogva Gearbox and hence this week’s title.
In this photo the dark Burgundy is the Aft Output end of the Nogva Gearbox and the bright Red is the flange on the propeller shaft which continues through the Tides Marine shaft seal system and out of the boat through the large AL prop shaft tube which is hidden here by the Blue Tides Marine silicone bellows hose.
This dimensioned drawing of the complete Nogva CPP or controlled Pitch Propeller, shaft, seal and flange will help orient things a bit.
Here I have gone below the boat rotate the CPP prop back and forth while pushing it hard forward so that the two flanges meet. A few months back we had spent quite a bit of time getting this alignment close as we installed the anti-vibration mounts on the Gardner and the Nogva and you read about that HERE, so now it was time for the fine and final adjustment to get these two flanges perfectly aligned.
As you may recall from previous posts the two flanges need to be eXtremely closely aligned both concentrically as per the illustration on the Left and also laterally as shown on the Right. Maximum deviation we are allowed is up to 0.005mm / 0.002in (human hair is about 0.05mm diameter) and ideally we are going for zero.
Needing such perfection I called on my Perfect Partner, aka Captain Christine to assist and although she is prone to laying down on the job (sorry, couldn’t resist) she was a huge help and made this task go much faster.
We check the alignment by inserting a thin feeler gauge, which is the silver strip you see here, that is a tight sliding fit into the space between the faces of these two flanges and see what the gap is at 12, 3, 6 and 9 o’clock. Any difference in size of the gap at these locations tells us how far it is out either horizontally at 3 & 6 o’clock or vertically at 12 and 6.
Adding to the challenge the prop shaft needs to be supported in its perfectly centered position which my red hydraulic bottle jack is looking after.
Mr. Gee, our Gardner 6LXB is solidly bolted up to the Nogva Gearbox so they are essentially an eXtremely solid single unit that is supported by six anti-vibration mounts such as the Silver one you can see on the Stbd. side of the Nogva Gearbox on the far Right in this photo. You can see the large vertical threaded part of these mounts with the large supporting hex nut on the bottom and smaller locking nut on the top.
To align the flanges vertically I need to turn the large nuts at the very front of Mr. Gee or these back two on the Nogva, Up/Down to move the Nogva flange until the gap is zero all the way around.
The process then is for me to go around the four Front/Rear mounts and turn those big nuts Up/Down while Christine moved the feeler gauges around the circumference of the flanges and called out the differences in the gap to me.
With Christine laying down in the space behind the Aft end of the ER Enclosure overtop of the Tides Marine seal at the bottom, there wasn’t enough room to take a photo but this previous shot shows what she was doing as she reached in with the feeler gauges to check the gap and call out the differences to me. Doing this all by myself was very time consuming so now you see what I called in the Big Boss to help out!
It still took us almost 2 hours but in the end we got the gap down to zero such that both flanges were touching all the way around.
With these two flanges now fully aligned we could insert the 8 hardened Grade 8 bolts through both flanges and torque them down to 120NM and the alignment was done!
White grease is TefGel 45 to prevent any corrosion and ensure that these nuts are just as easy to undo after many years on the job when we need to remove the prop shaft or the Nogva/Gardner for some reason in the distant future.
Many of these “little Big” jobs are like dominos in that as getting one done lets you do the next. So with the flanges aligned and mounts all torqued down I could now finish installing the Tides Marine SureSeal system. This is an eXtremely critical bit of kit as this is responsible for keeping the prop shaft cutlass bearing lubricated with a flow of fresh sea water AND keeping that sea water OUT of the boat!
Here is what the real deal looks like now fully installed. The Blue silicone “Articulating hose” in the illustration above, is double clamped onto the Stern or Prop Shaft Tube at the bottom and onto the Black SureSeal housing at the top.
The way this works is that inside the SureSeal are two stationary rubber lip seals with the 65mm OD Prop Shaft rotating inside them that keeps the water sea water inside the Prop Shaft Tube from being able to get past and into the boat.
We keep a VERY close eye on that Blue silicone hose over the years as if it were to ever rupture we would have an eXtremely large volume of water flooding into the boat!
The Black ring at the top is the very handy holder for a second set of replacement lip seals which you can change out with the boat still in the water as you don’t have to remove the Prop Shaft to replace them; just pry the old ones forward, cut them off and slide the new ones into place.
Last part of installing the SureSeal system is to provide a pressurized flow of fresh sea water into the Prop Shaft Tube which travels down the tube and lubricates the Cutlass bearing which supports the Prop Shaft as it exits the boat.
One of the reasons I chose to locate the Silver Heat Exchanger you see in the Upper Right was to be able to tap into its drain plug on the salt water side and use this as the source of pressurized salt water for the SureSeal. Nice short hose run and Cihan had that all hooked up in no time. The second Red hose on the Left goes up along the Aft wall of the ER with a ball valve on the end of it so that I can check the salt water flow rate when we first start up and from time to time afterwards and ensure that there is at least 4L/min / 1USG/min when the engine is idling.
Both those little Big jobs checked off the list and this is what the finished result looks like when peering down into the space Christine has now vacated on the outside of the Aft wall of the ER. Silver Gardner Coolant Heat Exchanger bottom right, Tides Marine SureSeal middle Left and Red Prop Flange middle Right and the Red Nogva Gearbox Oil Heat Exchanger at the top.
To keep the ER air tight a 6mm AL plate is bolted with a gasket over top and covered wtih the same composite grid floor plates as the rest of the Workshop and ER.
Cihan checked off another Big little job by plumbing the Sea Water and Engine Coolant water lines up at the forward Starboard/Right corner of Mr. Gee and the ER. It is pretty busy up there so I’ve labelled some of this plumbing to help you make sense of it. Can be a bit confusing as there are three fluids running around here; Sea Water that comes in via the Sea Chest just visible on the far middle Right here and through the Strainer and Manifold on its way to the Jabsco Impeller Pump and then out of that Pump and into the Engine Oil Heat Exchanger where it runs Aft exiting out and into that Silver Sea Water Heat Exchanger you saw up above in the SureSeal installation sequence.
Hope you got all that because YES children that WILL be on the Test on Friday!
Driving Big Red #2
Over on the opposite Port/Left side of Mr. Gee I finally have the drive system for our second Electrodyne 250Ah @ 24V alternator all designed and the adapters all machined so time to get them all installed. You may recall this photo from THIS previous blog post about installing what I call Big Red #2 and how I intended to drive it from the PTO or Power Take Off on the Gardner using a Jack Shaft I had from a previous job.
This is a quick screen shot from my Fusion 360 design for the adapters at either end of the Red JackShaft. Green cylinder on the far Left is the Output shaft from the Gardner PTO, Purple is the AL adaptor to couple the Jackshaft to the PTO and at the far Right in Gold is the steel multi V-belt drive pulley that came with the Electrodyne which I will machine with four threaded holes to bolt the other end of the Red Jackshaft to.
Note: Jackshaft simplified here to just a rod with flanges at either end.
This is the PTO from the Gardner with that Purple aluminium adaptor in the rendering above now pushed onto the Green PTO Output shaft and secured with four round hex head through bolts.
The Red Flange on the front U-joint end of the JackShaft barely visible on the Right will bolt to that AL adaptor with four more M6 SS bolts.
This is the Aft end of the JackShaft where this U-joint will be similarly bolted to that steel 8V pulley on Big Red #2.
The day came to an end at this point yesterday so not quite finished but this shot will show you how the whole JackShaft will connect the power from the PTO back to Big Red #2. This monster Electrodyne alternator could absorb as much as 10HP at full 250 amps of output which the gear driven PTO can put out easily and this Cardan or Jack Shaft should be more than up to the task.
Stay tuned for more though folks on the final installation of Big Red #2 next week AND just wait till you see the sweet setup I’ve come up with to drive Big Red #1 using a cogged timing belt setup that is now almost done.
Well Sand My Bottom!
Also not quite done but work continued this past week on getting the bottom underwater portion of the hull all primed and filled in preparation for applying the silicone based Foul Release paint, International InterSleek 1100SR.
The Paint Crew finished applying all the epoxy filler to smooth out all the welds and create a sleek smooth surface for the InterSleek 1000SR Foul Release top coat to come.
You can see some of the filled welds around the Prop Tunnel above and
….. the filleted edges around the AL threaded mounting disk for the Zinc on the Rudder. The circle on the Right is the filled in through hole we put in the Rudder to make it possible to remove the Prop Shaft without having to drop the Rudder. Because we hope to not need to remove the Prop Shaft for many years this hole is filled in to provide a fully flush curved surface on the Rudder sides to maximize a smooth laminar flow of water over the Rudder.
Sanding the first coat of epoxy filler on the Keel and Prop Tunnel into smooth large radius coves.
….. and the Aft Depth Sounder transducer.
…. and one of the 5 Sea Chests.
By end of the week they had the last of the 5 coats of International epoxy primer rolled as you can see around the Bow Thruster Tunnel, another smaller Sea Chest intake and Zinc mounting disk up near the bow.
Final coat of epoxy primer being rolled on Aft and we’ll see the application of the InterSleek 1100SR next week.
Grand Dame of Dyneema!
Lest you should think that The Captain only lays down on the job, this will prove that she sometimes sits!
But Christine has become and expert Dyneema splicer after doing so many as she installs all the Lifelines around the Main Deck. This are the AL Stanchions with their Lifelines now in place on the Aft end of the Port/Left side. The Tender will come On/Off this side so these 3 LifeLines have Pelican Hooks that are easy to release so we can then pull up the Stanchions and roll up the whole setup and stow when the Tender is aboard.
Closer view of how these Pelican Hooks and Thimbles work.
You start to appreciate how Christine’s Dyneema splicing expertise has developed so quickly when you start to count up all the splices required for each LifeLine in the system we’ve come up with. On the far Right is an endless loop that wraps around the AL Stanchion through a small AL D-ring to keep it in place and a SS Thimble captured on the end. Last step of this will be to lash the loop around the SS Thimble closed so that when it is undone the Thimble can’t come out.
Looking down the LifeLines to the Left you can see another splice at the Left end of the Pelican Hook and then further Aft/Left two more around these Black anodized Donuts or Rings you can see further to the Left. Christine leaves a gap of about 80-100mm / 3-4” between these two rings and then wraps multiple lashings between them to tension the life lines. And of course each of these Rings require yet another splice!
Hilmi and Ramazan continued their work inside Möbius this past week and we also find more of Captain Christine’s fingerprints up here at the Main Helm where she and Hilmi have been working to install and connect Boat Computer #1 you see here on the Port/Left side of the Main Helm Chair.
Its ultimate home will be inside this space behind the 50” Monitor on the outside and this AC/Heating Air Handler inside.
This space is normally covered by this hinged Rosewood back with a recess for the adjustable mounting system for the 50” monitor that doubles as both our movie watching entertainment screen when on anchor and then one of 4 screens for boat data and navigation when underway.
Down in the Guest Cabin Ramazan is completing the last of the Ado LVT vinyl plank flooring.
While the smallest by surface area it has ELEVEN removeable sections above the bolt on tank access hatches below so this area is taking the most time.
Pull out Bed in the Upper Left and Christine’s Office desk on the Right.
Six of those removable floor sections all weighted down while the adhesive dries.
Removable floor sections?
What removable floor sections?
Ramzan then stepped up his game (sorry) by moving up to install the vinyl flooring on the steps leading up from the SuperSalon to the Aft Deck.
Another tricky and time consuming bit of detail as each step has one of these handrail posts he needs to go around.
Which, as you can see, he had no trouble doing eXtremely well!
And that’s a wrap for the week that was January 25-30, 2021. Yikes! The first month of 2021 gone already???
Well at least it puts us another week closer to LAUNCH so as with “being shafted” that is all a very good thing.
Thanks for joining us for yet another episode here at Möbius.World. REALLY appreciate and value you doing so and please feel encouraged to add your comments and questions in the “Join the Discussion” box below.
