Fire, Feet & Fans – XPM78-01 Möbius Progress Update Oct 26-31, 2020

This week’s Progress Update is like they used to say on Sesame Street “Brought to you by the letter F” as Team Möbius worked on installing the FIRE Suppression System, FANS for extracting air out of the boat and getting Mr. Gee and his new literal Mate the Nogva CPP Servo Gearbox all mounted on their six FEET as well as aligned with the CPP Prop Shaft.  Even though there was 1.5 days holiday in the middle of this week for the big Turkish Republic Day on Wednesday and Thursday, our Team was very productive and got lots done so grab a favorite beverage and chair and join me for this week’s Show & Tell of all this Fun work that got done.

FIRE SUPPRESSION SYSTEM:

Sea-Fire automated shut down systemIf you were with us last week you will recall seeing Cihan and Hilmi installing and wiring up the Sea-Fire Automated Fire Suppression System components.  This week Hilmi picked up with installing all the wires, making all the connections and testing the automated system out.  This is the “brains” of the Sea-Fire system with all the relays for the various shut downs and “firing” the fire extinguisher.

Maus Xtin Klein fire extinguiserInside all other parts of the boat we simply have very good manual fire extinguishers which are these cool new type from Maus

However in the Engine room we and the various ABYC/ISO/CE standards require a fully automated Fire Suppression SYSTEM.

In addition to looking after the automatic triggering of the release of the 3M Novec 1230 extinguishing agent this system must also shut down the engine, close all the vent dampers, turn off the venting fans and sound the alarm.  This can also all be triggered manually with a Morse pull cable.
PXL_20201027_145930332Hilmi and Uğur worked closely together as they needed to coordinate between Hilmi laying out the locations on the Port side wall of the Workshop where he wanted to mount the Sea-Fire control box and where he wanted Uğur to cut the slots in the Alucobond panels.  The other Bronze box is one of the Kobelt engine control boxes and Hilmi now has the cables pulled through the wall panel slots below where he will be mounting the Sea-Fire control box.
PXL_20201027_124621641He will install the Sea-Fire controller inside this waterproof plastic junction box to keep everything all tucked away and well protected but first he needed to drill all these holes for the cable glands.
PXL_20201027_151347357Here is that junction box with the Sea-Fire box inside now mounted to the wall.
PXL_20201027_151405050Now that the Alucobond wall panels were in place Uğur could install the mounting screws through them into the aluminium frames behind.

The row of Black and Violet boxes up above are part of the Maretron monitoring system and Uğur will later install the L shaped AlucoBond corners to protect them.
PXL_20201028_065858024With the cables all pulled thorough their WT glands and the labels attached, Hilmi could strip the cable cover off to release the individual wires and start making all the connections to the control box for the different shut down relays and other controls.
PXL_20201030_140916231The standards also require that there be a control and indicator lights at the Main Helm which is where this round version is headed.  For testing purposes we just used that short ethernet RJ45 cable.

This remote confirms that the Fire Suppression system is On and working properly before it will allow you to start the engine and also allows you to set off the whole system from here as well as silence the alarm.
PXL_20201027_065633605That round remote control head will soon be installed in the angled dashboard up at the Main Helm amongst these other controls. 

PXL_20201030_085348709Once Hilmi and I had it all tested and all was working fine, the Grey ethernet cable you can see plugged in here, goes up to the Main Helm dashboard where the round controller will be mounted a bit later.
PXL_20201030_085324958And that’s it!  Everything all buttoned up and ready for more testing.

LIGHTS!

PXL_20201026_065811907More lights went in this week including these beautiful beasts which are Hella LED flood lights. 

This one will be mounted to the front “mast'” or arch at the Bow to light up the waters directly in front of us and others will be mounted to light up the water along both sides and off the rear of the boat.
PXL_20201026_065822896These Hella Work Lights are a thing of pure beauty and joy to my heart and mind not only for their incredible candlepower but their Black bodies are ribbed cast aluminium and that bracket is all 316 stainless.  What’s not to love?!!
PXL_20201026_065925676We also have several of these Italian made Osculati Faro LED spot lights for when we want a more narrow beam to go greater distances.
PXL_20201026_065933082Similar to the Hella lights these ribbed bodies are also all cast aluminium with SS mounting hardware and epoxy sealed wiring to help them survive and thrive in the harsh marine environments and weather we will be subjecting everything to.
PXL_20201026_065756952More “Hella a light” was the arrival of these two LED lights on flexible stalks that will be mounted at each helm for when we need to read something up close.  These have both a bright white LED as well as a dimmer Red light to help retain our night vision when on passages.
PXL_20201027_065426457As exciting as all those other lights are to me, THESE are the ones that really make my day as these are my working lights inside my Workshop, Forepeak and Engine Room. 

PXL_20201026_100322036For me and I think most others, there is nothing that beats having GREAT lighting when you are working and these babies are truly amazing in how much bright white light they blast out into all the spaces where I work aboard.  All those lumens are augmented all the more as they bounces off all those White Alucobond surfaces on all the walls and ceilings such that the whole space is eXtremely well lit.  Just wait till we peel off all that protective plastic film and these surfaces are pure White Light!


PXL_20201027_065433983For those interested, here is a shot of the back of one of these LED work lights.  They would have thousands of great applications and are highly recommended by this worker.

TOWERS of SHOWERS!

PXL_20201028_070950901Cihan was his usual Productive Plumber self again this week and he has now has these gleaming Stainless Steel “shower towers” all plumbed and working.


Shower Tower illustration

This is a slightly different model than ours but it will help you visualize what they look like in action.  If I don’t come out of shower session with this then I must be doing something really wrong.  To say nothing of how much fun our GrandKids will have with it as there is a matching unit in the Guest Cabin Shower.
PXL_20201028_071112613Which looks like this.
PXL_20201028_071010439The new fittings he needed arrived this week so Cihan was also able to finish mounting these beautiful SS towel wormers that are another work of art and engineering to me.
PXL_20201028_071017954There are also two matching units of these towel warmers, one in the Guest Bathroom and one that will go on the far wall you see here in the Master Bathroom.  The four smaller holes you see here (click to enlarge) are for the SS mounting tubes and then the larger ones on the bottom are the threaded SS fittings where the PEX hot water lines emerge.
PXL_20201030_085650524These Turkish made beauties are just fabulous to work with and this square bodied tap to turn the hot water on/off is another good example of the “little things” that make all the difference with both their solid heft being solid SS as well as the squared off design which has them blend into the overall sculptured look and give no indication that they are also functioning taps.
PXL_20201030_085642430One step back to show you the whole towel warmer.
PXL_20201030_085628524And a few more steps back to show you the whole Shower and Bathroom space.  The etched glass walls that will form the corner of the Shower where I am standing to take this picture are due to arrive next week and just wait till you see how this space looks with them all installed and lit up!
PXL_20201030_085740296The Bio-Bidet 1000 on our VacuFlush toilets are now all installed along with their controls.  This controller is wireless and clips into a small plastic hanger on the side of the cabinet.
PXL_20201030_085747959Or you can run the basic functions with the SS control head you see on the aft left side of the seat and see that all is working well with the LED indicator lights on the Right.

I received a number of queries and comments about these bidet units so I will let the following pictures do all the talking to answer those.
PXL_20201030_085759966Human contact required to avoid any “surprises” when curious onlookers are checking things out.
PXL_20201030_085817233And you can study this better shot of the remote controller to figure out the rest.

Oh, and yes, there is a matching unit for all our guests in their cabin too.
PXL_20201030_085859290Elsewhere in the Master Cabin, Serkan has the templates for the two mirrors on these cabinet drawers temporarily attached to check that they are the just right size before they get sent off to the glass and mirror shop.
PXL_20201030_085953365And he is also making up similar templates for the other mirrors in our Master Cabin such as this one on the inside of the Cabin Entrance door.

eXhausting!

PXL_20201027_142912971Cihan also received the 127mm / 5” ID exhaust hose this week so he got starting installing the first short length underneath the Day Tank on the Starboard / Right side of the Workshop.
PXL_20201028_070555675This relatively short length hose, about 1.2m / 4 ft, connects to the AL pipe welded into the Engine Room wall on the far Left and carries the exhaust gasses over and out the same size AL pipe welded into the side of the hull.  These special rubber hoses are able to safely carry the exhaust gasses because they have all been well cooled by the sea water injected into the hot exhaust gas up at the top of the Engine Room.

eXtraction is eXhausting TOO!

PXL_20201030_133114227As you can see, it was all hands on deck quite literally as the boys got to installing all the extraction fans and dampeners inside the Vent Boxes on the Aft Deck.  This is the Stbd/Right side Vent Box where the large rectangular ducts coming up out of the Workshop and the Engine Room exit and there is an extraction fan for each one.
PXL_20201030_133125528This is the Vent Box on the Port/Left side where the opening on the upper Left goes all the way down to the floor of the Engine room and keeps Mr. Gee well fed with clean fresh air.  The slotted square on the bottom Right is for the extraction of air out of the Guest Cabin. 

The box on its side near the middle directly in front of the slotted opening is one of the demister or mist eliminator units which removes most of the salty humidity in the air before it heads down into the ER.  More on that in a moment.

PXL_20201030_133128748

Here is a close shot of the upside down box in the lower Right foreground above and this is an example of how the various extraction fans are attached to their outer facing mounting plates which bolt to the Vent Boxes.
PXL_20201031_084757981Like this.
PXL_20201030_133240074This is an upside down Dampener that Uğur is attaching to its mounting plate which then bolts to the Vent Boxes similar to the extraction fans.

These Dampeners are installed on both the Intake Supply Air going into the Engine Room as well as the Extracted Air being pulled out and they are normally in the closed position so that no salty air is getting into the ER when we are not running Mr. Gee which dramatically reduces the consequences of salty air in the ER most of the time.
PXL_20201031_084813580Here is what one of those Dampeners looks like when mounted into the Vent Box.  The Orange box on the far Left of the Dampener is the motorized automated controller that Open/Closes the Dampener plate.  And the White round cover you can just make out on the Left side of the Vent Box is to provide access to our hand if you ever need to manually Open/Close the Dampener.
PXL_20201031_084829913Over on the opposite side Vent Box, the Dampener is mounted vertically inside the long rectangular duct mentioned above that takes the fresh air down to the bottom of the Engine Room.  Dampener door is closed as you can see in this photo and as part of the start up procedure these dampeners are rotated open by their 24V electric motors and stay that way until just after we shut Mr. Gee down OR when the Sea-Fire system shuts everything down in the case of a fire.
PXL_20201031_084844279I’ve received quite a few questions about these Mist Eliminators or Demisters which remove most of the salty humidity from the air before it goes inside the ER so here are a few close up shots so you can see how these work. 
PXL_20201031_084849894This is the rear view and basically the way these work is that these black plastic vanes inside force the air to flow through a convoluted path where the water droplets condense out of the air. 
PXL_20201031_084900856Hard to capture on camera but these Black plastic vanes are very complex somewhat wave like shapes inside with equally complex surfaces.  These are all the result of years of research and testing apparently to perfect their ability to extract all that harmful salty water vapour which then runs out the little SS drain hole you can just make out in the bottom center of this photo.  There is then a plastic tube that takes this extracted water down to the Sea Chest in the ER and back out to sea where it belongs.

See what I mean?  eXhausting right?!!

PROPULSION SYSTEM ALIGNMENT:

PXL_20201028_095953948.MPLastly for this week let me show you a bit about the night shift I’ve been on this past week working with some expert motor and CPP propulsion system aligners from another shipyard next door.  Meet Emre on the Left, Hussein standing on the Right and that arm in the lower Right is ………….
PXL_20201028_100001344

…….. Hayretttin who is busy choosing the right 0.05mm feeler gauge as we are about to alight the output flange of the Nogva Servo Gearbox with the matching flange on the CPP Propeller Shaft.

Of course you have all met Mr. Gee, our Gardner 6LXB many times by now so he needs no introduction.
PXL_20201027_161449899I won’t go into too much detail on this whole alignment process as it is likely not of too much interest to most, but here is what we are working on.  The Red flange on the Right side here is attached as you can see to the forward end of the big 65mm OD propeller shaft going aft to the 4 bladed CPP propeller, and the matching Maroon painted flange that it is now butted up against is the flange on the Output shaft of the Nogva CPP Servo Gearbox.  The goal is to get the inner faces where these two flanges come together PERFECTLY lined up.
PXL_20201028_093742501.MPAfter several hours of wrangling the now solidly connected Mr. Gee and Nogva Servo Gearbox assembly into position such that the center of both of those flanges perfectly line up, we now need to use the threaded rods on the six different “feet”, or flexible mounts, four of which attach Mr. Gee to the 25mm thick Engine Beds and then two which similarly attach the Nogva Gearbox to those same Engine Beds. 

We use very thin 0.05mm / .002 inch feeler gauges to check 360 degrees around where these two flanges meet as this is the maximum allowable difference allowed.  Zero space between them is ideal which we pretty much achieved by nights end with ever smaller adjustments to these six mounting feet.
PXL_20201027_143240526Prior to all this, I had done that centering I mentioned above to get the Push/Pull Pitch rod with the male threaded end poking out of the center of the Prop Shaft on the Right, exactly lined up with the female threaded piston extending out of the Output Flange on the Nogva Gearbox on the Left. 
PXL_20201027_141349603There is a hydraulic pump inside the Servo Gearbox, hence the name, which pushes that piston forward and aft as you move the Pitch control lever at both helms.  This in turn moves that Pitch Control Push/Pull rod fore and aft which is what is translated into rotational movement inside the hub at the center of the CPP Propeller which thus rotates each of the four prop blades in synch with each other to vary the pitch of the prop from zero which would be like “neutral” no thrust to the boat fore or aft and then at our choosing either rotating the blades and thus increasing their pitch to push the boat either forward or reverse.


PXL_20201027_141353695Using a dial gauge I was able to move Mr. Gee + Nogva assembly to put the center of that output piston spot on the center of that threaded push/pull rod inside the prop shaft and then rotate the Nogva output flange to thread the rod into it. 


PXL_20201027_150518040There is a precise measurement of how far to thread that rod in so that the pitch rod is centered in its travel which is what you see here, and then I could tighten this lock nut to hold it in that position.

Once this was all done I could mount the two halves of that Red prop shaft flange and do the alignment I described above.
PXL_20201027_161439955Et voila!  A perfectly aligned Engine, Servo Gearbox and CPP prop shaft!

Now we take it all apart again after carefully marking the position of the mounting bolt holes in each of the six flexible feet as we need to lift the whole assembly up in the air to give us enough room to drill all those holes in the Engine Bed for those bolts.  Next week’s night shift will be doing this and then going through the whole alignment procedure one last time and then bolting the six feet down to their final positions.


I know this is riveting stuff so do stay tuned for all that excitement next week!

Hope this wasn’t all too boring and that you will consider joining us again next week.

Hot Water AND Hot Air, Oh my! Progress Update XPM78-01 Möbius Oct. 19-24, 2020

Whew!  What a week this has been.  A shortened work week for Christine and I as we traveled to Kapadokya, as it is correctly spelled in Turkish but Anglophones spell it Cappadocia, with two dear friends, Philip & Nancy who flew in from Switzerland and Australia for a fabulous albeit much too short visit with us.  However you spell it Kapadokya should be pronounced “firkin’’ AWEmazing”!! 

Captain Christine is busy making a special video just for all of you and will post that separately later today.

**UPDATE:  You can watch Christine’s beautiful video of our AWEmazing hot air balloon experience over the equally inspiring landscape of Kapadokya HERE NOW!

***  For more details and photos of our time in Cappadocia including her new video are now available in Christine’s blog post HERE.

But Wait There’s More!  She has also already added a great wide angle shot overlooking Kapadokya on our balloon ride and added this to the “slider” photos at the top of the Mobius.World blog so be sure to check that out too.

For now, I’ll just tease you with a few shots that I managed to grab as best I could with my mouth agape.

Meanwhile back at Naval Yachts Team Möbius put in a very full week and made lots of progress on many fronts so I’ve got lots for you in this week’s Show & Tell.  Grab your favorite beverage and reading spot and join me for this week’s dive into the building of mv Möbius.

Hot Air!

Hot Air Baloons Kapadokia WIDE 2It is going to steal the show anyway, so let me start with the “Hot Air” part of this week’s title as in our awemazing hot air balloon ride early Tuesday morning with Philip & Nancy.
Hot Air Baloons Kapadokia WIDEAs incredible as it may be, the biggest attraction of Kapadokya is the incredibly unique geography filled with what many call “fairy chimneys” which are tall, cone-shaped rock formations clustered in Monks Valley, Göreme and elsewhere.
My photos won’t hold a candle to Christine’s video so I would recommend you go watch her video HERE right NOW before you go any further to get a much better sense of this experience. 

No rush, it will only take a few minutes for you to watch,  I’ll wait till you come back ………………………..

……………… See what I mean? 

Say after me…………. firkin’’ AWEmazing!!

Now that you have a better sense of this incredible natural wonder of the world in Kapadokya, I encourage you to also click to enlarge the photos above and below so you can check out some of the geography of this region.  Kapadokya is a UNESCO World Heritage site and as they noteOther notables sites include Bronze Age homes carved into valley walls by troglodytes (cave dwellers) and later used as refuges by early Christians.”

Hot Air Baloons Kapadokia filling our balloonOur original reservation for a sunrise hot air balloon ride was for Monday but this was unfortunately cancelled when the aviation authority for the region issued a weather warning.  But we were up at 5am on Tuesday with fingers crossed as they started to luff our balloon and fill it with hot air from these two propane burners while we anxiously awaited word that we would be allowed to take off.
Hot Air Baloons Kapadokia Lift off with CK   Hakan SoloOur pilot Hakan, or “Hakan Solo” as Christine dubbed him as he is a huge Star Wars fan, was absolutely fabulous both as a person and as a encyclopedic knowledge of the area and as you saw in the video, a VERY skilled hot air balloon pilot. 
Hot Air Baloons Kapadokia Lift OffHakan received word on his VHF radio that the authorities had approved the balloons to fly and with a few more blasts of propane flames we had lift off!

As you may have noticed we were not the only hot air balloon lifting off and there were a total of 150 balloons in the air that morning.
Hot Air Baloons Kapadokia Lady in RedAnd as if our senses were not already on overload this “Lady in Red” was but one of about ten Brides and Grooms who were taking advantage of this very popular location for wedding photos.
Philip   NancyWe only had them for three days in Antalya and three in Kapadokya but the “density” of our experiences that we managed to pack into those few days was eXtreme and we now have even more memories of their visit with us.

Hot Water!

While we were away Team Möbius stayed in close contact with me via WhatsApp and the short video below is what Cihan sent me on Monday to share this significant milestone of the first hot water produced on Möbius and tested at the Vanity Sink in our Master Cabin.

PXL_20201023_150631206Taking a few steps back, this is where that Vanity Sink lives, front and center of our Master Cabin.  In spite of the rather rough surroundings this solid glass sink is already stealing a lot of attention as it lights up with that LED light above and even more so when you clear out the protective foam behind the sink and the LED strip light in the bottom of the cabinet causes those blues to become electrifying.

Can’t wait to show you the final result once the Master Cabin is fully completed and all the protective plastic, cardboard and painters tape comes off.  We can’t wait to see it ourselves!
PXL_20201021_070152125The ever productive Cihan had a very busy week and can you guess from this photo what his next project was?
PXL_20201021_084258608Correct!  He is mounting our two SS “Shower Towers”.  This one is in the Master Shower and mounts at a 45 degree angle in the corner on the far Left.
PXL_20201022_063821792And this one is in the Guest Cabin Shower.  In addition to their great looks in our eyes, one of the many reasons for choosing this “Shower Tower” style is that all the plumbing is contained within the unit itself rather than being hidden behind the shower walls.  The first photo above shows this quite well.

One of our five primary principles for our XPM is lowest possible maintenance so this factors into all our decisions and being able to easily remove this whole shower tower in the future provides me with great access to all the hoses, mixing valves, etc.  The only thing inside the walls are the continuous runs of PEX tubing for the hot and cold water lines.
PXL_20201022_105350625Back in the Workshop, Cihan was busy getting many other systems fired up for the first time including this Webasto IsoTemp 75L / 20USG Calorifier that holds all our DHW or Domestic Hot Water and he adjusted this mixing valve to set upper limit of the hot water coming out of this unit.
Webasto IsoTemp interiorThis cut-away demo unit shows how this IsoTemp unit has multiple sources to heat the water inside;

  1.   SS loop filled with heated water from our Kabola KB45 diesel boiler.
  2. A second (not shown) SS Loop connected to the engine coolant on Mr. Gee (Gardner 6LXB engine)
  3. 230V electric heating element (small U loop in the middle)
    PXL_20201022_102159668We expect to use the first option above, this Kabola KB45 as our primary source of heating our DHW as it is so quiet and efficient but we will take advantage of the “free” heat from Mr. Gee whenever he is running and then perhaps use the 230V heating element on the few occasions when we are plugged into Shore Power.
    PXL_20201022_102152199Hilmi was working on the KB45 this past week as well and he has now finished the electrical connections for the Kabola with the mounting of the white Siemens thermostat you see on the upper Left corner.
    PXL_20201022_102147973It is showing just 23C / 74F as this is the ambient temperature in the Workshop but we expect to fire up the Kabola in the next few weeks once we have some diesel in one tank and will show you that when we commission this unit.
    PXL_20201022_111544009Our DHW also flows through the In-Floor heating PEX lines so Cihan was checking for any leaks and also bleeding the air off of these manifolds in the Basement where the circulation pumps push hot water through the three independent loops of PEX tubing inside the floors of each of the three cabins; Guest, Master and SuperSalon.
    PXL_20201022_111553164These SS manifolds came as very complete units with build in temperature gauges on both the Upper Supply Manifold and lower Return Manifold as well as three RED flow meters along the top of the Supply manifold, three White flow adjusters on the bottom Return Manifold and bleed valves and drains on the ends of both manifolds.
    PXL_20201021_070723809Cihan is also testing all the various plumbing system for proper operation and checking for any leaks and had a problem with this diaphragm switch on the High Water extraction system under the floor on the Port/Left side of the Workshop so he has the floor grate out right now.
    PXL_20201023_150627895Back up front in the Master Shower & Head, Serkan has been busy with multiple jobs including gluing the Corian countertop in the Head/Bathroom.  They use this clamping system very often of cutting lengths of wood that they bend into place and use the force to push in this case from the ceiling down to the Corian countertop below. 

While they are at it, they used longer sticks to clamp and glue a composite water tank access hatch in the floor.

Let there be Light!

PXL_20201021_070639313.MPOur “Sparkie” aka Electrician Hilmi was as busy as ever this past week and very “illuminating” as he installed and connected most of the light switches onboard and Möbius now has her own interior lights on rather than all the industrial construction lights we’ve been using.

Apologies for the strange colour in this photo but Hilmi now has all our indirect LED strip lighting working such as these in the Corridor from the Engine Room to the stairs up to the SuperSalon with the Guest Cabin entrance on the middle Right.
PXL_20201021_070741154However the real eXciting illumination for me is that he has also been installing these super bright LED fixtures on the ceilings of the Workshop, Engine Room, Basement and Forepeak.

Check out THIS example along the Starboard/Right side of the Workshop and see how light and bright it is in there now with nothing but these three LED lights overhead.
PXL_20201021_070703669Even brighter over here on the Port/Left side of the Workshop overtop of my very long, and VERY messy, Workbench. 

I don’t expect too many of you to understand but this makes my little heart go all aflutter as I can now see so clearly what I’m doing as I work here. 

However, knowing what I’m doing is another matter all together!
PXL_20201023_103904195Same story inside the Engine Room as Hilmi mounts more of these eXtremely bright industrial LED light fixtures overhead of the Stbd side of the ER.
PXL_20201023_150053827I took a few photos when it was dark out just before leaving last night to show just how bright these working spaces are now.  This is peering down into the ER from up on the Aft Deck.
PXL_20201023_150526168And here is what it looks like at night peering through the ER entry door.  In addition to these overhead lights I will also be putting in some LED strip lights underneath the two lengthwise AL Engine Beds to light up the voluminous bilge area down there where of course everything seems to end up. 

Ask me how I know?!!
PXL_20201023_150714239More exciting milestones thanks to Hilmi such as having these three Victron BMV7122 Smart Battery Monitor Gauges lit up for the first time.  Next week I will get round to configuring them with all the right settings which only takes a few minutes.

We have 24 FireFly Carbon Foam L15+ 4 volt @ 450Ah cells which are wired 6S4P meaning that there are four sets of six cells wired in Series (6S) to create four 24V @ 450Ah groups.  Two sets are then wired in parallel to create Bank A and Bank B which are each 24V @ 900Ah and then these two Banks are paralleled to create the overall House Battery Bank of 24V @ 1800Ah


XPM 6S4P House BatteryHere is how that looks schematically.  Two of the three BMV’s thus report on the condition of Bank A and Bank B and the third monitors the total 1800Ah House Battery.
PXL_20201021_101716509Some smaller but no less important jobs Hilmi ticked off this week included this 120V + 230V waterproof connection underneath the Upper Helm Station on the SkyBridge.
Aft Deck Lewmar winch switchThis push button switch for the monster Lewmar 65 EST winch on the Aft Deck that will be most often used to raise/lower the Tender Davit Arch.  This switch is being mounted on the Aft side of the Starboard Vent Box which also houses the 230V Kenyon Frontier electric Grill/BBQ.
Cat7 cable in ceiling of WorkshopAnd running ethernet CAT7 cables in the ceiling of the Workshop.  We have ethernet cable running throughout the boat for all the networking and connections between all our many electronic gadgets which we depend upon so highly and this also helps “future proof” the boat for adding more later.

AlucoBond Goodness:

Of course all those LED lights are working so well because Nihat and Uğur spent several days this past week mounting all the White AlucoBond panels on the walls and ceilings of the Workshop and the Engine Room.

AlucoBond panel contruction illustrationThese AlucoBond panels are working out eXtremely well as they create a super tough White powder coated surface of the outer 0.5mm layer of aluminium with a 4mm thick mineral core which is all non-combustible to meet and exceed all fire regulations.
PXL_20201022_102112781.MPIn addition to the ceilings and walls of the ER and Workshop, they also installed the AlucoBond on the interior of the Doghouse where you enter the Workshop from the Aft Swim Platform. 

First they install the supporting framework for the AlucoBond panels using 30mm aluminium L-bar and flat AL plates welded to the frames and stringers of the hull and Doghouse framing.
PXL_20201023_070907940Then they use SS self tapping screws to secure each AlucoBond panel to the AL frames.
PXL_20201024_132815153The AlucoBond can be easily bent to create corners for places such as the panel around the Hatch in the forward end of the Doghouse.
PXL_20201024_132823383The AlucoBond is easy to work with using standard carbide tools such as jig saws, router bits and circular saws.

This makes creating cut-outs such as this one on the Left for the filler tube on the 55L / 14.5USG AL hydraulic oil tank for the Kobelt steering system.

Where edges of cut AlucoBond exist we cover them with U-shaped rubber edging which you can see if you click to enlarge this photo.
PXL_20201023_150441678Even before the protective film with all this Black & Red printing is removed you can see how well these White AlucoBond surfaces reflect the light from just these four LED lights in the ER.

Swim Platform Step& Storage Box

PXL_20201021_084210056Stepping over the high sill of the Watertight door from the Swim Platform into the Workshop was a bit of a nuisance so Uğur quickly solved that problem by fabricating this Step/Storage box.
PXL_20201021_084211309.MPAn eXtremely KISS design (Keep It Simple & Safe) so I didn’t bother firing up Fusion 360 to create a model and drawings for Uğur as there are basically just two pieces of 5mm AL plate; one welded into the Swim Platform and Stbd side Stair and the other for the hinged top that creates the Step Tread.
PXL_20201021_084816733A small strip along the back for the SS piano hinge to bolt to and a small U-channel on the far Right side to act as a gutter for water run off.

Then tack-tack-tack goes Uğur ’s MIG gun and the Step is all framed up.
PXL_20201021_151521227Bend a thin strip around the two outside edges of the hinged lid and mount the SS piano Hinge.
PXL_20201021_151539597We have enough of the EPDM edge trim we are using for the Deck Hatches to use here to make this Storage box fully waterproof as the Swim Platform is often quite wet when we are underway with following seas and such as well as regular rainy days.


Et Voila!!  We now have an eXtremely easy step In/Out of this doorway and a very handy Storage box on the Swim Platform for shower supplies, snorkel gear, etc.  Thanks Uğur!

Nogva CPP Enters the Scene

PXL_20201023_152045714Hmmmm……………

What are Cihan and Nihat up to after ours in the dark up on the Aft Deck with the ER Hatch wide open?
PXL_20201023_152636948And what is THIS dropping out of the sky into the beautifully bright Engine Room?
PXL_20201023_152939048Aha!  It is Mr. Nogva CPP Servo Gearbox coming in to join forces with Mr. Gee our Gardner 6LXB main engine.

With a CPP (Controllable Pitch Propeller) we don’t have a transmission per se as there is no forward/reverse gearing.
Nogva Prop   shaft illustrationInstead, by simply rotating the four propeller blades in synch we can smoothly change from “neutral” to Forward to Reverse and the push of a lever.
PXL_20201023_160200503The Nogva Servo Gearbox bolts directly to the massive aluminium flywheel housing on Mr. Gee as both have a standard SAE1 flanges and bolt patterns.
PXL_20201024_070718794so it was very quick and easy to bolt these two best buddies solidly together so that they form a single massive propulsion unit.
PXL_20201023_155234799Hussein works for a big shipyard next door where he specializes in engine/gearbox/prop shaft installation and alignment so he comes over when he gets off work at around 18:30 and he and I work on this installation and alignment.

He helped me get the Nogva dropped in place and bolted to Mr. Gee and then I stayed on a bit later into the evening to get everything all ready for the next and eXtremely important step.
PXL_20201023_160205191Getting the Nogva dropped in place and bolted up to Mr. Gee was very quick and easy, now comes the slower part of aligning the output flange of the Nogva Gearbox which you can see at the top of this photo.
PXL_20201024_132849603The prop shaft and flange are fixed in place vertically and athwartships (Left/Right) by the bearings which center it inside the AL prop log tube at the bottom.

So alignment involves moving the output flange to line up precisely with the matching flange that mounts on the forward end of the 65mm / 2.6” prop shaft.  I took this shot looking forward towards Mr. Gee to show that we are already reasonably close and now need to move the Gardner/Nogva buddies over to the Port/Left side a bit and down a bit.
PXL_20201024_132900596Here is a side shot to help show how these two flanges meet up.  Adjusting the angle and height of the Gardner/Nogva assembly is accomplished by adjusting the height of their respective “feet” or “flexible mounts”.
Click to enlarge this photo and you can see how the Noga foot/mount at the bottom center can be adjusted Up/Down by turning the two large nuts on the vertical threaded shaft of the mount/foot.  The similar rear foot on Mr. Gee can be partially seen in the very bottom Right corner of this photo.  More on all that in next week’s update.

Tides Marine dripless SureSeal assemblyFor the observant and curious wondering what that blue articulated hose with the little Red “hats” is, here’s your answer; it is the Tides Marine dripless SureSeal.
PXL_20201024_132834823The prop shaft has to pass through the aluminium shaft log tube and out through the aft end where the 4 bladed 1m diameter propeller sits so that puts a very large hole in the boat that needs to be dealt with and hence this seal between the prop shaft and the prop log tube.

The little Red “hats” as they are called are used to protect the SureSeal rubber lip seals from being damaged as you slide them onto the prop shaft.  These simply pull out and are split to remove from the shaft when done.


In next week’s Möbius Progress Update I will pick up from here which is where I left off late last night (Saturday here) so do stay tuned for the next episode of “As the Prop Shaft Turns”.

Go AND Whoa?! Progress Update XPM78-01 Möbius Oct. 12-16, 2020

Picking up where we left off last week I will use this same theme of “Go and Whoa” as we work on both systems that help us get going such as our Upper Helm Station for navigation while simultaneously working on our anchoring system to when we want to say “Whoa” and know Möbius will stay put.  Apologies in advance as I need to make this week’s update a bit of a rush job as we have some dear friends visiting us who have just flown in from Switzerland and Australia, which is quite a feat these days, and so Christine and I are taking a few days off to do some travels with them.  So without any further ado, let’s jump right into this week’s Show & Tell aboard Möbius and see what Team Möbius have been up with this past week.

Meet Rocky!

MVIMG_20201012_144130If you were with us last week you’ll recall seeing Christine and I paint our 13mm / 1/2” galvanized anchor chain with different colours at 10 meter / 33ft intervals as our way of counting how many meters of chain we are letting out for the depth of water we are anchoring in.  We then flaked the 110m/350ft of chain back onto its wood pallet and used the forklift to put it up on the foredeck ready to be fed down into the chain bin up front.  We will hold off doing so until we get the anchor itself properly mounted on the Port/Left side of the Bow so we’ll just leave the chain here for now.
PXL_20201014_082740608.MPMeet Rocky! 

I had installed a 70kg/155lb anchor on our previous 52ft/16m sailboat and we we eXtremely happy with how well it worked and we never dragged once so we decided to go with Rocna again on Möbius. 
Our anchoring or “Ground Tackle” system is one of the most critical of all for us as we anchor almost every night of the year and depend on our anchoring system to keep us solidly anchored to the bottom in ALL conditions.  I am not a fan of having multiple anchors at the bow as I want our “main” anchor to be the one that goes down every time. 


PXL_20201014_082745285.MPAs usual for us and the XPM Series we upsized our anchor a wee bit and had this 110Kg/242lb Rocna shipped over to us from Canada where they are made, at the end of last year.  Since then, Rocky has been hibernating underneath Möbius all wrapped in his shipping bubble wrap so it was fun to finally do the unveiling this week and welcome him aboard Möbius.
nav_12180__While Rocky is the only anchor we have at the Bow we do carry several other anchors for different purposes one of which is this all aluminium Fortress X125 31kg/70lb anchor at the Stern. 

NAV_12181__We will typically put this out as a Stern anchor to keep us in a fixed orientation under some conditions and perhaps used as a kedging anchor when (never if) we go aground and need to help pull us off.

As per this photo, Fortress anchors have many advantages being so light, easy to store when disassembled and works particularly well in soft muddy bottoms. 
Bow & Anchor renderNext step was to do some fine tuning up at the Bow to create the bespoke Anchor Rollers which Rocky will nestle into whenever he is off anchor duty on the sea floor below us.  This quick & dirty render hopefully shows how this rather unique Anchor Roller design we have come up works.
PXL_20201014_085404065.MP

If you look closely, you can see one of the key features we built into this design which is that the flared ends of the two side cheeks of the Anchor Roller brackets, made of 15mm/5/8” AL plate integrally welded in as part of the Bow framing, will match the angle of the flukes of the Rocna.  This way we can cinch Rocky’s flukes up tight against these cheeks when we head out on passages and he essentially becomes part of the hull.  No movement, no noise even when the Bow is bashing through large waves.


PXL_20201014_085425409.MPDuring the build we had left these two cheeks a bit oversize to do this fine tuning so I needed to be able to pull Rocky in the just right “cheeks to flukes” position so Uğur, Nihat and I rigged up this length of square steel tubing and lashed it to the Bow Pulpit rails and hung the chain block off the end to pull Rocky aboard.
PXL_20201014_092903547.MPThis setup was as my Dad might have said “The Bees Knees” as it allowed us to easily move Rocky up/down and push/pull him in/out as I tried out different positions with this rather tricky geometry to get the axis of the SS pins that will have two nylon rollers on them in just the right spot.
PXL_20201014_091158726.MPHere for example you can see that the angle of Rocky’s flukes are not quite matching up with the AL cheeks.
PXL_20201014_133919289.MPSo the rollers need to be repositioned slightly so the shank end of the anchor seen here, goes down to close that gap.
PXL_20201014_130841381.MPI also wanted to make sure that the forward most end of Rocky was a bit aft of the forwardmost part of Möbius which is at the Rub Rail of the Bow, so we marked off a line parallel with the flukes and Uğur trimmed about 15mm off the ends of the AL cheeks which allowed the anchor to move a bit aft.
PXL_20201014_133549593.MPWelcome to your new home Rocky!

I then mocked up some wooden rollers and pins and was able to move these around to find the just right Goldilocks position such that they would bring Rocky into this home position when cinched up tight up on deck.  I may add some hard rubber strips to the end surfaces of those cheeks to make sure everything stays completely silent and there  is no movement here even when we put this under eXtreme stress in big seas.

More to come as we machine and install these Anchor Rollers in the coming weeks.

ENGINE ROOM SYSTEMS:

Sea-Fire system schematicAlongside our Anchoring System at the very top of our critical systems list is the automated fire suppression system in the Engine Room.  Christine worked directly with Justin at Sea-Fire International in the UK and they designed the system you see here.
Sea-Fire NFD 550M spray head photoWhile we have extensive smoke/heat/fire/CO detection systems and manual Maus fire extinguishers located throughout every area of Möbius, the Engine Room requires a fully automated Fire Suppression System.  This both automatically activates the 3M Novec 1230TM extinguishing agent used in all Sea-Fire systems as well as shutting down Mr. Gee and all the fire dampers to completely seal off the ER so the Novec 1230 ** , which is stored as a liquid and discharged as a gas, can quickly and fully extinguish the fire. 
**  For those, like me, interested in such details, according to the 3M site “Novec 1230 fluid extinguishes a fire before it starts by rapidly removing heat. In a typical total flooding system, the fluid is stored as a liquid in cylinders pressurized with nitrogen. Automatic detection sensors trigger release when the fire is at the incipient stage, extinguishing it in mere seconds.  Novec 1230 fluid evaporates 50 times faster than water. In fact, you could soak a paperback book in a bath of Novec 1230 fluid and within a minute, pick it up and read where you left off.”

This Novec 1230 is a relatively recent development to replace previous types of gas based fire extinguishers which depleted the oxygen in the space and used other chemicals which were harmful and deadly for any humans who were in the space at the time.

The net result we care about with selecting this system is that any fire would be put out within seconds AND because it is a waterless fire suppression solution, it leaves no residue and is electrically non-conductive, the fire is extinguished without any harm to the engine, electrical devices and other equipment within the ER so that we should be able to fix up whatever problems led to this fire and then continue on our way.

PXL_20201016_121105751.MPCihan was back with us on Thursday and mounted the Sea-Fire NF 550AM bottle solidly to the AL framework of the ER.

If you look closely (click to enlarge any photo) you can see he has also mounted the Red mandatory manual activation cable off to the far Left with its handle on the outside of the ER beside the door.
PXL_20201016_084921743Cihan and Uğur also mounted the Kobelt Actuator to make sure it did not interfere with the Sea-Fire bottle and pull cable.  This Kobelt Actuator converts the electronic signals from the control levers at the Main and Upper Helm Stations into mechanical movement that moves two push/pull Morse cables; one that moves the throttle lever on Mr. Gee and the other moves the Pitch Control lever on the Nogva CPP Servo Gearbox.
PXL_20201016_084859661In the unlikely event that both electronic control systems at the Upper and Lower Helm Stations should fail, you can manually control the throttle and pitch using the two SS handles you see here with the Black knobs on the end. 

Redundancy (2 independent Helm Controllers) and manual backups as always!

VICTRON COMMISSIONING:

PXL_20201016_100344206.MPAfter the different systems on boats the size of XPM78-01 Möbius have been fully installed, they need to be set up and tested to be working properly by the manufacturer.  This is process is referred to as  “commissioning” and it was another exciting milestone for us this week when one of our most primary and critical systems, our extensive Victron electrical system was commissioned by Victron.

Yusuf rejoined us and he, Hilmi and myself spent several hours down in the Basement which is where our “Victron City” is located, with my laptop connected into the Victron network via the White ethernet cable via the little Blue/Black Victron MK3 to USB gateway you see atop my laptop.
PXL_20201016_101945890.MPBut where is the Victron person you may ask?  He is on the other end of the phone that Yusuf is talking with here while simultaneously be connected into my laptop via a remote desktop app so that he can take direct control of my laptop and then use the Victron Connect software to configure and test all our Victron equipment.  Ahhh, the wonders of modern technology.

Worked like a charm and was a very cool experience as the Victron expert updated all the firmware on each Victron device, set up all their parameters and configuration files and tested them.
PXL_20201016_105024472.MPThe internet connection way down in the Basement where the signals need to go through multiple walls of aluminium wasn’t the best for uploading all the firmware and configuration files but that was no problem as I simply moved my laptop up to the Aft Deck and ran a longer ethernet cable from the Basement.

Now that all the devices are setup we can remotely connect to them using the Victron Remote Management portal or VRM as well as via Bluetooth, WiFi and USB.
PXL_20201016_104019305.MPI was very impressed with how well this Victron remote management allowed us to do the full commissioning virtually.  Hard to show this in photos but one of the smart things Victron does is let’s you cause the LED lights on any bit of kit to blink so you can unambiguously identify the specific device you are working on or sending files to.

Welcome to the 21st Century Möbius!

GLASS at LAST!

PXL_20201013_091437521.MPWell we don’t’ have the glass for all our windows and hatches just yet BUT the reason this scene was very exciting for us to see this week is that what Nihat and Osman are doing here is making the plywood templates for each piece of glass on the boat.  This is the one for the Port Deck Hatch on the Aft Deck.

SKYBRIDGE HELM STATION:

MVIMG_20201012_111418Last week Uğur finished welding up this all aluminium Help Station and got it bolted into the stand up in the SkyBridge.
PXL_20201013_084347631.MPThis week Hilmi was able to install all the wiring
PXL_20201013_084353344.MPWhich come up through this penetration between the Helm Station and the Base below.
PXL_20201013_151604529This is most of the equipment prior to installation.
PXL_20201014_123316127.MPNow partially installed.
PXL_20201015_064042190.MPNow just waiting for the Engine Start/Stop switches to arrive.

We will hold off installing the two 24” touch screens until just before launching when things will be much cleaner onboard.
PXL_20201016_140322355.MPFor now, they are all hermetically sealed away as there is still a lot of aluminium and other dust flying around.
And th-tha-tha- That’s ALL Folks!  for this week’s XPM78-01 Möbius Progress Report. 

Sorry this one is a bit rushed and I’ll be back with more again next week.

See you then,

Wayne

Getting Ready to Stop and Go?! XPM78-01 Möbius Progress Update Oct. 5-10, 2020

The focus this week was on building the aluminium Console for the Upper Helm Station in the SkyBridge (the GO part of this week’s title), getting Mr. Gee his fuel supply, continuing to check off more electrical and interior jobs and prepare our anchor chain for anchoring (the Stop part of this week’s title). 

We were delighted to welcome back more members of Team Möbius as they return from the other boats they’ve been working on so let’s jump right into this week’s Show & Tell so you can see it all for yourself.

SkyBridge Helm Station

Upper Helm Console perspectiveHere is the design we came up with for the aluminium console that will hold all our navigation equipment for the Upper Helm Station in the SkyBridge.  Click to enlarge this (or any image) to see some of the items that will be installed in this console and I’ll put a list of all of these below.

Upper Helm Console layout center dimsAs shown in this layout drawing, the equipment that will be mounted in this console include:

  • 2 Side by Side 24″ LiteMax NavPixel Daylight Readable Touch Monitors
  • Furuno 711C Autopilot Control Head
  • Vetus Bow Thruster Joystick Model BPAJ
  • Maxwell VWC 4000 Windlass Up/Down Control
  • Kobelt Engine Throttle and CPP Pitch Controls
  • Kobelt Pitch Gauge
  • Standard Horizon GX6000 Fixed-Mount VHF Radio
  • Kobelt Control Switches & Remote Walkabout plug-in socket
  • SH SCU-30 Wireless Access Point
  • Exterior Lights switch panel
  • Engine Stop/Start buttons
  • Horn button

Upper Helm Console perspective RhinoAlthough the SkyBridge area is quite well protected by the solid roof above created by the aluminium frame for the 8 320W solar panels mounted on top, and the removable plexiglass windows which wrap 360 degrees around the whole SkyBridge, it will still be exposed to wind and rain at times so we needed to build a waterproof console to protect all these critical and eXpen$ive electronics.
We had been working on the design of this console for a long time and were very pleased to be able to enlist the help of Burak who had been our 3D modeler when we first started working with Naval 3 years ago, to work out the details and finalise this design.  One additional design element we needed to accomplish was that this whole console needed to be removable for two reasons.  First being that it needs to be removed when we convert the boat to “hunkered down/Canal mode” and lower the articulated roof.  And secondly Christine and I want to try out having this Upper Helm Station in different locations in the SkyBridge as we use the boat for the first year or so.  We think that its current location at the Aft end of the SkyBridge will work out best but we won’t know for sure till we can live with it in different scenarios and different positions.

IMG_20201006_134238Burak sent over all the 2D construction drawings last week and so Uğur jumped right in on Monday morning and spent most of this past week taking this console from start to finish by Friday.  Let’s follow along as he works.
IMG_20201006_163445It would have taken another week or more to send out all the AL plate to be CNC cut and I think Uğur enjoyed the chance to go back to some “old school” ways so he quickly laid out all the parts directly on the AL plate and cut out the pieces with the in-house bandsaw and a cutting disk on his angle grinder. 
IMG_20201007_102035As we have tried to do throughout the design and build of XPM78-01 Möbius, we KISS’ed (Keep It Simple & Safe) the design of this console so there are only 8 pieces in total and they are all made out of 5mm / 3/16” flat AL plate which are easily tacked in place.
IMG_20201007_095728To provide ready access for installing and maintaining all the electrical connections and components inside this console we made the whole back side a removable plate that will be bolted in place with a watertight gasket.
IMG_20201007_110249With a quick check that all the dimensions and angles were all correct, Uğur got to work doing all the finish welding.

BTW, for those who might wonder why all the photos of welding have these lines in them it is due to the MIG welders being the newer Pulse type and the camera freeze-frames these pulses.
IMG_20201008_093015With the welds cleaned up a bit Uğur laid out the various cut-outs for each item to be installed on the dashboard and then cut these out with a hole saw or cutting wheel.
IMG_20201008_162003We are still waiting for a few switches to arrive but we have all the primary components so Uğur and I did a quick check to make sure they all fit properly before continuing.
MVIMG_20201008_175448Next it was time to finalise the location of the console on top of the foundation built into the SkyBridge (and for Cihan our Master Plumber to get in this quick cameo!)  The two cushions on the Port/Left side allow someone to comfortably join the person on watch as well as a great spot to lie down for a nap up here.
IMG_20201009_093944After trying a few different spots we settled on this positioning with the same amount of overhang around the three sides.
Llebroc Upper Helm ChairThis is our Llebroc Helm Chair which will soon
IMG_20201009_175908…….. reside here, in the center of the space behind the dashboard.

IMG_20201009_093800This penetration on the inside provides a watertight pass through for all the cables.  Once all the cables have been installed and all systems checked that they are fully functional, this and all other penetrations throughout the boat are filled with certified “goo” to create a fully watertight seal.
IMG_20201009_093852Here is how the Upper Helm Station it looks from the back side. 
IMG_20201009_175928Holding the camera at about eye height here to check the sight lines which are great as you can easily see the whole forward end of the bow anchor area.
Kobelt 7176 Walk About RemoteWhenever we prefer to have an even better close up view of around the boat, we have one of these Kobelt 7176 “Walk-About” remote controllers at both Helms. 

With 10m / 33ft of cable, I’m not willing to trust wireless for this critical control, we can stand almost anywhere on the boat from the Swim Platform to the Bow, either side deck and from anywhere in either the Main or SkyBridge Helm areas and have all the controls literally at our fingertips when docking or take this remote controller to wherever we are sitting.

The two side levers control Throttle and Pitch and up on top are controls for Rudder, Bow Thruster, CPP Clutch and Horn.  Can’t wait to try all these out on our upcoming sea trials once we launch.


And Yes, Launch Date is still “Thursday”, just don’t ask which one! Smile


Plumbing Progress:

IMG_20201008_094241We finally have Cihan back full time again (we hope!) and he was his usual busy productive self all over Möbius.  Cihan and I started by working on the two heat exchangers …..
IMG_20201007_151751…….. that needed to be mounted in the very aft end of the Engine Room.
IMG_20201007_150606We built in this removable section of the flooring to provide full access to this important area where the prop shaft enters the boat.  The composite grid flooring lifts out and then this aluminium floor plate can be unbolted and removed as well.
IMG_20201007_151707Access is particularly important whenever I need to service the “dripless” Tides Marine SureSeal Drip Free Self-Aligning Shaft Seal that keeps all the water out of the joint where the prop shaft exits the log tube.
Tides Marine dripless SureSeal assemblyI will cover more details when we are installing this SureSeal but here is a quick overview of how it works.
IMG_20201007_151716Today though we wanted to access the very aft ends of the two Engine Beds on either side where we wanted to mount these two Bowman heat exchangers.  The red one on the far Port/Left side is for cooling the hydraulic oil in the Nogva CPP Gearbox and the Silver one on the far Stbd/Right side is for cooling the Gardner’s water/antifreeze engine coolant. 
Bowman Heat Exchanger cut away viewBoth of these heat exchangers have cool seawater being pumped through their outer shells while the oil is pumped through a round “stack” of CuNi (Copper/Nickle) tubes that you can see here in this cutaway illustration. 
Fun Fact:  Bowman is another one of the world leading industrial companies we have found here in Turkey and so it was fun to find that our Nogva Norwegian CPP system came with that Red Bowman Heat Exchanger.

IMG_20201008_094254My apologies for getting too busy to get too many photos of this installation of these two heat exchangers but the basic flow of the seawater is that it first enters the Left end of the Silver Heat Exchanger at the top of this photo, exits out the rear and then flows through the Gray (protective wrap) hose on the far Right here where it will enter the aft end of the Red Heat Exchanger at the bottom.  Inside the Engine Room, the seawater exits the front end of the Red Bowman Heat Exchanger through another rubber hose that goes up to the Halyard SS mixing elbow on the Gardner’s wet exhaust system and then exits the boat through the large Exit Sea Chest in the ER.  Much more to come on all that once we start installing the exhaust system in the next few weeks.
IMG_20201007_130735Another new plumbing addition that Cihan installed this past week is the small little circulation pump with the White faceplate you can see at the bottom middle of this photo of the underside of the Stbd/Right side Workbench in the Workshop.
IMG_20201007_130740These Jabsco/Xylem 24V “vario” pumps are very cool and very eXpen$ive but boy do they work well.  These are a relatively new pump generation that are super quite with minimal energy consumption, shaftless spherical motor and permanent magnet technology.
On Möbius we are using this D5 Vario 38/700B pump to keep hot water circulating through our DHW (Domestic Hot Water) loop that ensures that there is always hot water immediately available to every hot water tap and shower on the boat.  No more wasting time and water while you wait for hot water to come out of the sink faucet or shower nozzle!


IMG_20201007_130544Speaking of hot water, the Captain aka Christine, is eXtremely eXcited about Cihan installing two of these SS towel warmers; one in each cabin’s Head/Bathroom!

Christine has been wanting to have one of these for years and after a very long and winding road to find these Goldilocks just right versions, she will finally have one in our Master Cabin as will all our guests in their Bathroom.
Laris towel warmerYet another example of the Turkish manufacturers making eXtremely high quality products, Christine fell in lust for these “Laris” model SS towel warmers from Hamman Radiator.
IMG_20201007_145715The towel warmers attach to the walls with these very clever SS tubes which Cihan first attaches to the walls using an expanding bolt on the inside of each tube. 
IMG_20201007_145725

And then there are four round SS pegs on the back of the towel warmers which slide into these tubes and are locked in place with the little set screw you can see on the bottom here.

The two SS square fittings the bottom are the water valves to control the flow of hot water through the towel warmer. 


Laris towel warmer upper corner photoHere is what the finished mounting looks like.

Many won’t understand, but to my eye, all of this hardware and the towel racks themselves are just beautiful works of art and engineering that are part of our “boat jewelry” collection on Möbius.

Interior Progress:

IMG_20201009_175606Looking around our Master Head/Shower/Bathroom do your sharp eyes might spot a few other new additions?

One job Serkan just completed is the mounting of those two SS latches now installed on those bottom two cabinet doors underneath where the sink will mount.
IMG_20201006_152851And if you look very closely you will see that the White Corian countertop has arrived.  There will be a clear glass partition that extends up that slot between the shower seat and the ceiling and will be sealed to that vertical surface at the end of this countertop.
IMG_20201009_175617And what is this new addition that just showed up this week beside the VacuFlush toilet?
IMG_20201009_175623Aha!  That’s the wireless remote control panel for the BioBidet BB-1000 Supreme bidet seat.  It clips into a holder mounted on the cabinet so the curious can remove it and discover all the MANY functions available.   The same BioBidet is installed in the Guest Cabin as well BTW.


Surely you didn’t think I put the eXplorer in XPM for no reason did you?

IMG_20201009_175715More examples of how XPM78-01 Möbius is a true world eXplore can be seen in another new addition this week as Hilmi starts installing all our Vimar “Arké Metal” switches and plug ins.  We have designed Möbius to be a true “World Boat” and so she has both 120V 60Hz and 230V 50Hz AC plugs like these throughout the boat.
IMG_20201009_175805We also have wired CAT7 ethernet plugs spread throughout the boat for maximum internet speeds.  This one is tucked away below the “floating” shelf on Christine’s side of our King size bed.
IMG_20201009_175811And these are what the matching Vimar light switches look like.  Of course these will all look MUCH better once we remove all the protective plastic coverings and do a good cleanup prior to launch, but until then we are very glad to have all the interior surfaces covered up while construction continues.
IMG_20201009_175517And here is Hilmi installing a set of four of those Vimar switches for the LED lights around the stairwell leading down into the Master Cabin.
IMG_20201007_130452Serkan has also been busy in the Master cabin adding finishing touches such as these solid Ro$ewood handholds on the “Swiss” (as in Swiss Army Knife) door that is the door for both the entrance into the Master Cabin and the full length hanging locker as it is here.
IMG_20201007_130457He needed to radius both ends of these so that they cleared the door jambs when closed on the Entryway.  The upper panel will soon be covered with the same Green/Gray leather you see throughout the Master Cabin walls.

Aluminum Finishing:

IMG_20201010_151441Nihat also had a very productive week as he took on the eXtremely big job of finishing all the exterior aluminium surfaces.  We’ve settled on the “brushed” look that these 3M abrasive discs create when used with a random orbital sander such as this pneumatic one in the photo here.

Let us know what do you think of this look but we are very pleased with it.

Feeding Mr. Gee!

IMG_20201006_174218I managed to make more time for Mr. Gee again this week and focused on installing his “feeding” system to deliver the Goldilocks just right amount of scrupulously clean diesel fuel.

This is one of his six fuel injectors that have been refurbished to factory new condition by Michael and his crew at Gardner Marine Diesel at the Gardner “factory” in Kent England.  Injectors just don’t get much better or simpler than this.  NO electronics just a simple supply connection under the Red seal on the Right and a matching return connection on the Left.
IMG_20201006_174242Each injector slides into the tubular hole you can see underneath the tip of the injector here.
IMG_20201006_183919Then one of these lever arms is tightened down using the castellated nut just to the Left of the Red cap here.  This lever presses the angled end of the injector body into its matching seat inside the tubular hole in the cylinder head and forms a perfect seal to keep all those literally eXplosive forces inside the cylinder where they belong and where they then supply all the mighty “draft horsepower” and torque that Mr. Gee delivers to our propeller.
IMG_20201009_095258Now each of those injectors need an equally robust set of piping to deliver the diesel fuel to/from them so my next job was to clean up all these steel fuel lines and give them a couple of coats of shiny black epoxy. 

Can’t have any bare steel on Mr. Gee that would just rust now can we?!
IMG_20201010_182610Here is what those shiny Black steel fuel lines look like when they are connected to the bottom outlets on the Fuel Injection Pump and then go up to the injectors in the cylinder heads through the AL valve covers I have set in place here.

Again my apologies for being too busy installing all these fuel components to take more photos but I will take more this coming week and put them into next week’s Progress Update for you.

For now I hope this quick shot of where I left of yesterday (Sat. Oct. 10th) will do.

 

Yachts Play Games Bula Bula Right?!

IMG_20201010_124709Christine and I spent Saturday morning doing a job that believe it or not, we have long been looking forward to; painting the length marking strips on our 13mm / 1/2” galvanized HT anchor chain. 

The joy in this job is that it reminds us that in the not too distant future (we hope!) we will be using these marks to tell us how much anchor chain we have let out in the latest anchorage we have just arrived at.

We started by dragging all 300 meters / 328 feet of chain off the factory pallet onto the shop floor and arranging it in 10 meter long loops with paper underneath both ends where we would be spray painting the chain.
IMG_20201010_125720There are a LOT of different ways to mark an anchor chain and even more opinions about which is best but we have both anchored thousands of time in our marine lives and find that painting different colours onto the chain and then adding some matching coloured nylon zip ties is the Goldilocks just right method for us.
IMG_20201010_133147We paint a different colour combination each 10 meters / 33’ and to help us remember the distance of each colour we came up with the acronym YPGBR based on the colours of paint we have used this time.  As you might figure out from this photo, YPGBR  stands for Yellow-Pink-Green-Blue-Red which is the order of the colours we painted onto the chain every 10 meters. 

These are the odd numbered 10 meter marks starting with Yellow at the first 10m mark at the top here, then:

  • Pink @ 30m,
  • Green @ 50m,
  • Blue @ 70m
  • Red @ 90m
    IMG_20201010_133158At the other end of the loops we use a combination of the colours to mark the even starting lengths of;
  • Yellow/Pink @ 20 meters
  • Pink/Green @ 40m
  • Green/Blue @ 60m
  • Blue/Red @ 80m

Confusing right? 

Nope!  Easy for us to remember when the YPGBR acronym stands for is:

  • Yachts
  • Play
  • Games
  • Bula Bula**
  • Right?!!
    For those who might wonder, Bula is the Fijian greeting, always said with great Gusto, which we learned so well from all our years cruising in Fiji

Once the paint dried we flaked the chain back onto the pallet and it is now ready to be pulled aboard into its Chain Bin inside the Forepeak but that will have to wait for next week’s Progress Update here on Möbius.World.

Thanks as always for joining us and be sure to add your thoughts and ideas in the “Join the Discussion” box below.

Well Flip me Tender! XPM78-01 Möbius Progress Update Sept. 7-11, 2020

Another slow week aboard Möbius unfortunately with the combination of lack of staff to another boat ‘Caledonia” that launched on Friday and an unexpected 4 day week due to two workers testing positive to Corona 19.  Those two men who had both been working together on Caledonia have been quarantined but and the rest of that team were all tested so we are hoping that we can get back to work tomorrow, Monday here. 

However, Uğur and Nihat made great progress on the Tender and I got in some solid days working on Mr. Gee so I’ve got lots to show you and let’s jump right in to this week’s Show & Tell.

INTERIOR WORK:

Serkan our Hardware specialist, has continued with the installation of all the many latches and gas lifts on the cabinetry doors and drawers in all three cabins.  Below is a short little video that will do the best job of showing you how these work.

IMG_20200908_183718Now that we get to try these out we really like how our design has all worked out for these Galley Garages.  As you can see in the video above, even when you have messy fingers while cooking, a simple flick of your finger allows the door to fully open and move out of the way so you can grab whatever you need inside.
IMG_20200908_100836These gas filled lift cylinders snap into SS mounting balls which you screw to the inside of the cabinet and the door so while Serkan needed to spend a bit of time figuring out the exact placement of these mounts with the first door, it goes very quickly after that.

I thought the instructions on the plastic bags the cylinders come in would do the best to show you how this works.
IMG_20200908_100812

The Silver coloured one I’m holding here is a Lift cylinder so it compresses when you close it and is what is used on the Galley Garage doors.  The White one on the counter is a “drop” cylinder so it works in the opposite direction to slowly lower our fold down doors where you flip the latch open and then the gas cylinder slowly telescopes out to smoothly lower the door to its fully folded down position rather than free falling open.

NAVIGATION LIGHTS:

IMG_20200908_101351Exciting for Christine and I to see that we are now at the stage where our OGM Navigation Lights are getting mounted. 

Uğur and I came up with this simple design for the mounting bases that go on each side of the coaming around the SkyBridge for our Red/Green side nav lights.
navigation-light-positionFor those not familiar with COLREGS, the standards governing navigation lights for ships of all sizes, this graphic shows the nav light requirements for a power vessel a over 20m/65ft length.
IMG_20200910_093457For the Port/Starboard Red/Green lights must have a Horizontal View Angle of 112.5 degrees and >70 degrees Vertical so they must be mounted at an angle of 33.75° from the centerline of the vessel.
IMG_20200910_093452I’ve been using these OGM nav lights for 15 years with great success so sticking with what I know for Möbius.  The body is CNC milled out of a solid block of aluminium and then the 2 nautical mile LED sets behind a glass lens and the whole light assembly is “potted” in epoxy so there is nothing to come loose or leak.  KISS at its best!

Nav Lights on Main ArchUp on top of the Main Arch we have these 2 OGM lights, a Single White Steaming Light: Visible over a 225 degrees arc forward with the all around 360 degree White Anchor Light mounted above.

Yet to be installed at the end of the Aft Deck is one more OGM that is a Separate White stern light covering 135 degrees Aft.
IMG_20200910_093538Just up front and off to the Port side of Red/Port light is this GPS head which is dedicated to providing the satellite based GPS data to ………….
em-trak-A200 Class A AIS image………….  our em-trak Class A AIS transceiver that is mounted overtop of the Main Helm.  We like to have a lot of redundancy for our GPS data so this GPS head is one of five that we have all together onboard Möbius.

Given our speed and size we decided to upgrade the AIS Class B we have had on our previous boats to this Class A unit and the table below explains why. 

With Class A we get bumped up to high priority over other boats with Class B, increased power and range broadcasting at 12.5W vs 2W


AIS Class A vs B features chart from Digital YachtDynamic information is transmitted every 2 to 10 seconds while underway and every 3 minutes while at anchor vs every 30-180 seconds on Class B.

Not cheap, but one of our five principles for Möbius is Safety, so when it comes to Safety at Sea we don’t compromise.
Courtesy of Digital Yachts site here is a nice graphic (click to enlarge) and overview of AIS (Automatic Identification System).
How AIS works illustration from Digital Yachts

AIS is the mariner’s most significant development in navigation safety since the introduction of radar. The system was originally developed as a collision avoidance tool to enable commercial vessels to ‘see’ each other more clearly in all conditions and improve the helmsman’s information about his surrounding environment.
AIS does this by continuously transmitting a vessels identity, position, speed and course along with other relevant information to all other AIS equipped vessels within range. Combined with a shore station, this system also offers port authorities and maritime safety bodies the ability to manage maritime traffic and reduce the hazards of marine navigation. Due to the great safety benefits offered by AIS, this technology was made compulsory throughout the world in 2002 for all passenger ferries and vessels over 300 gross tonnes.


IMG_20200910_093916Nihat is one of our most efficient and hard working members of Team Möbius so while he was waiting for Uğur to lay down more of the finish welds on the Tender, he would move over a few feet to work on cleaning up the welds on the three part Davit Arch. 

Here Nihat is working on the long horizontal cross member of the Davit Arch and the thick plate you can see on the far Left in that photo has a matching plate on top of the vertical legs of the Arch. 
Tender Davit double pipe arch YigitMy thinking with this design is that it makes it much easier for us to dismantle the whole Davit and store it on deck when we want to transform Möbius into her “hunkered down” configuration for canals or in hurricane/cyclone conditions when we would also lower the SkyBridge roof.

Prepping for Propulsion:

IMG_20200908_183052I was able to spend much of this four day week inside the Engine Room on Möbius getting Mr. Gee ready to have his best buddy our Nogva CPP Servo Gearbox mated to him.  This is looking forward at Mr. Gee’s massive 100+Kg flywheel which now has the Nogva aluminium SAE14 frame bolted on. 

Each of those rounded “teeth” around the inner circumference will fit precisely with the matching grooves on the hard rubber Flexible Coupling which is bolted to the input shaft of the Nogva Gearbox.
Nogva SAE 14 Flexible Coupling to Gardner illustration Like this.  Makes for an eXtremely solid yet eXtremely quiet flexible coupling of the 180 Draft Horsepower coming out of Mr. Gee to the Nogva and on to the CPP propeller.
IMG_20200908_181317Turning around to get this shot of the SS Prop Shaft protruding out of the AL Prop Log Tube I needed to get the Prop Shaft perfectly centered in the Log Tube so I made up this little jig to do so.
IMG_20200908_183128Just a short bit of AL tubing machined so it snugly fits into the space between the Prop Shaft and the Log Tube like this.  The two halves of the Red Nogva flange you see in these photos will be bolted to the end of the Prop Shaft on the bottom Left here and then this flange must be very precisely aligned with the matching flange on the output of the CPP Gearbox.  I’ll show you all that in a week or so.

Mr. Gee Gets Dressed:

IMG_20200907_173655Remember that big 24V starter motor you saw being rebuilt and painted the past few weeks?  Well here is what it looks like when slid into place on Mr. Gee’s Aft Starboard side.
IMG_20200908_164502More Gardner ingenuity to make removing the starter so easily, it slides straight aft like an artillery shell into a cannon and you can rotate it to any position and then cinch it up tight with the silver band clamp you see here.  I’ve put the terminals on the bottom so the big cables will be well protected by the starter above and have a straight run out below.
IMG_20200908_164511It also felt great to finally get to fit this Bronze Beauty aka the Engine Oil Cooler, put in place just above the starter and below the Exhaust & Intake manifolds.

Seawater will be pumped into the 90 degree Bronze/Copper pipe at the far end and then out the curved copper pipe in the bottom center here.
IMG_20200907_173226Up at the Front Stbd/Right side of Mr. Gee is this centrifugal coolant/water pump that is driven by a gear off the timing chain inside the cast AL Crankcase on the Left. 
IMG_20200910_140356The Coolant/water is pumped out through the AL manifold on the Left here and into the two Burgundy Cast Iron Cylinder Blocks.
IMG_20200910_153834Surrounded my more Beauty, this time in the form of one of our two “tiny” Red 250Amp @24V Electrodyne alternators.  Time for me to start fitting these monsters to equally robust mounts I still need to finalise.  For this one I’m going to reuse the same method the original Gardner engines did by using strap mounts same as you just saw on the Starter above, to solidly attach the alternator to those three curved you can see are cast into the Crankcase. 
IMG_20200910_153848Then two straps wrap up and around the alternator body and are cinched down with a threaded stud.

As you can see, I also need to finish assembling the big Red Electrodyne Junction Box for all those White wires coming out of the alternator body on the Right.  The Junction Box is just sitting loose right now as I measure everything up prior to fitting this in place onto Mr. Gee’s side.

Flip my Tender!

IMG_20200908_095002Uğur picked up where we left off last week with some final checks on the critical positioning of the cast aluminium mounting frame which Castoldi supplies with their 244 Direct Drive Jet.
3123That cast AL Mounting Frame is shown in Blue in this render and the Grey plate on the right is a partial view of the 20mm / 3/4” thick AL plate Transom with what I’m calling the “Mickey Mouse cut-out” to create the whole opening in the boat where the Castoldi will bolt to.
Castoldi 224DDThis is what the whole Castoldi 224DD looks like with the Jet nozzle on the Left and if you look back and forth between this and the render above you will be able to see the mounting holes around the whole jet drive casting and how they will fit into the opening above.
IMG_20200908_100003Cast aluminum is often a different mixture of the alloys than aluminium plate and can be challenging to weld so we wanted to sure there would be no problems welding this cast AL Frame into the Tender’s Hull plates. 
IMG_20200908_100040Those three cross members spanning the Frame above are temporary so Uğur did a test weld on this one and a small scrap of 6mm AL plate and then we all took turns trying to break the weld with long levers.  Didn’t budge or crack so we are good to go.
IMG_20200908_111134Always a bit of hesitation when it comes to cutting holes in the bottom of our perfectly good boat and especially one THIS BIG!  But it was soon done and we’re ready to start installing the Frame.

But first, we decided to flip the hull 180 degrees to make working on the bottom so much easier so strap yourself in and I’ll do another rapid fire set of photos that many of you have said you’ve been enjoying to walk you through the whole flip.
IMG_20200908_112920Handy having a Forklift is rather handy!
IMG_20200908_113158One last check fit of the cast Frame into the opening in the Hull.

You can also see the outline of the Mickey Mouse cut out etched ty the waterjet cutter into the Transom.
IMG_20200908_121139We debated whether to have this Mickey Mouse cut out by the CNC waterjet when all the plates were being cut but we decided it would be better to leave it until now when we could double and triple check its position and get the jet drive in the exact right location. 

Aluminium is such a great material to work with and even at 20mm/ 3/4” thick, Uğur was able to make quick work of cutting out the majority with a jig saw while I kept the blade cooled with cutting oil spray.
IMG_20200908_163025Ta-DA!

I think even Walt would be proud don’t you? Smile
IMG_20200908_163039Frame tacked in place now ensuring that one of the most critical aspects is that the front edge of the Frame on the far Left here and thus the body of the Castoldi that fits into the Flange, are flush with the bottom plate of the Tender.
IMG_20200908_170237Seen from above it looks like this.
IMG_20200909_093541Frame now fully welded into the Hull and Transom.
IMG_20200909_094149Captain Christine arrives just in time for the start of the Big Flip!
IMG_20200909_094350Airborne now.
IMG_20200909_094839180 degrees, Half way there…..
IMG_20200909_102917140 and counting ……….
IMG_20200909_103032180!  We’re flipped.
IMG_20200909_115739Nihat wastes no time jumping in with his angle grinder to start cutting the deep V grooves so Uğur can get full penetration with his MIG gun as he follows soon behind with the first full length welds.
IMG_20200909_115753Like this.
IMG_20200910_093719MIG welder up and Uğur gets down to business!
IMG_20200909_120443Time for me to get busy as well as I need to remove a few bits and pieces from the fully assembled Castoldi still sitting inside its factory wooden box.

This is the forward leading edge of the Jet Drive where the water initially enters through the grates underneath the far Left of the cast AL body.
IMG_20200909_120451I need to remove this electric driven hydraulic pump which powers the Jet’s Steering nozzle and Jet Drive Bucket.

Input Flange where the jack shaft from the 110 HP Yanmar HTE will connect via a flexible coupling and jack shaft.
IMG_20200909_120505Propulsion direction Forward/Reverse/Sideways is accomplished by moving the big Bucket overtop of the jet’s nozzle which is done by moving the rod in this hydraulic cylinder on the Stbd/Right side.
IMG_20200909_120511That cylinder above connects to the Bucket like this.
IMG_20200909_123841I’m very impressed by the design and build of this Castoldi Jet Drive and it only takes me minutes to remove all these parts and have the Jet Drive stripped down and ready to be installed in the hull.
IMG_20200910_093731A well tuned MIG welder sounds like a very big buzzing honeybee and all the while I’ve been prepping the Castoldi, Uğur has had his MIG gun buzzing merrily away
IMG_20200910_093856…. as he lays down all those first long lengths of full welds and then goes over them all again with the second final bead.
IMG_20200910_165852Et Voila!

  • The bottom of the hull and the Castoldi Frame are all welded in place.
    IMG_20200910_171652We double check that the Frame is still properly aligned and that the heat from all the welding has not warped anything but all is well.

Time to cut out those temporary supports in the Cast AL Frame.
IMG_20200910_171916And Mickey is now ready to receive his Italian Bride!
IMG_20200910_172045Who has now also been flipped over 180 and ready to be lifted out of her box and into the Tender.
IMG_20200910_172733Forklift makes it all very easy and able to lower it slowly in place.
And unfortunately I have to leave you and the Castoldi hanging at this point as I was too busy helping Nihat get the Castoldi lowered in place and do all the measuring and checking of the fit to be able to take any more photos.  Sorry!!

But I’ll be back to pick up with all this next week so I’ll  leave you with this mini cliff hanger for now and hope that you’ll forgive me and join me again next week.

Thanks for joining the adventure and be sure to leave all your questions and comments in the “Join the Discussion” box below.

Let There Be LIGHT! Progress Update XPM78-01 Möbius Aug 31-Sept 05, 2020

Similar story this week as the past few; excellent results and exciting progress on Möbius wherever Naval craftsmen have worked, just not as many of them working as are needed to finish and launch Möbius as quickly as possible when they are assigned to work on other projects in the shipyard.  But forward progress towards the eventual Launch Date made none the less.

As I gathered all my photos from the past week together there seemed to be a theme of light than shone through many of them in different ways and hence this week’s title.  So let me go shine some light on all of these and jump right into this week’s Show & Tell and show you some of those eXcellent results and eXciting progress from this first week of September 2020.


INTERIOR PROGRESS

IMG_20200819_182436Lots of Light shining through in the interior such as this is one of very many LED light fixtures which are inserted into the removable ceiling panels in all the living spaces.  These are made by the big Italian lighting company BCM and we are using their BCM Charlotte 80 LED lights for most living areas.


IMG_20200819_182434

These are the newest generation LED lights which are significantly more efficient so their wasted heat is very small and the large heat sinks you may be familiar seeing on such LED fixtures are no longer required so these lights are much smaller and cooler, both literally and figuratively.


IMG_20200819_182603

Typical Italian craftsmanship and quality, they are easily set into the holes cut into the ceiling panels by folding the two spring loaded arms out of the way and then orienting the outer polished SS frame however you wish.

All our lights are LED so our overall energy consumption and heat generation is kept to an absolute minimum and all lights are on dimmer switches so we can easily have the Goldilocks Just Right lighting in every location and situation.


IMG_20200826_095519

Lights over larger living spaces such as these overtop of the Lounge on the Left and the Dinette on the Right are a Warm White, about 2700 – 3000K.


IMG_20200826_095538Whereas task lighting situations such as these in the Galley are a cooler  Neutral White of 4000-6000k.  We also have some up here in the SuperSalon that can be switched to a coloured Red/Blue light when we are on night passages and want to maintain our night vision.
IMG_20200831_161453Serkan, our interior hardware installer, continues to make his way throughout the interior installing all the positive locking latches and gas struts the many cabinet drawers and doors.
IMG_20200829_102823I’ve shown these to you before but I’m still madly in love with what are to me jewellery like SS lifting latches for all our drawers and cabinet doors.

Single finger lift like this to unlatch and then they are spring loaded so they automatically self latch when the Blum soft close feature of each drawer slide gently pulls the drawer closed.
IMG_20200831_145256Hakan ordered this range of telescoping gas spring struts so we could try them out and chose the ones that were just right for our Garage Doors and fold down cupboard fronts. 
IMG_20200901_094437In the case of these Galley Garage doors, when you lift the latch the gas springs automatically raise the doors to their fully open position and hold them there while you get at whatever you need inside.
IMG_20200902_095446Whereas for cupboard doors such as these lower two in my Corridor Office where the space behind is too shallow for a pull out drawer, the gas struts gently lower the door down when you unlatch them.
IMG_20200903_102446In the case of “regular” drawers such as these below Christine’s Office desk, no struts are needed because when you unlatch them the drawers slide out effortlessly on their Blum SS roller bearing drawer slides and then close automatically with the soft close feature when you give the drawer a gentle push to close.
IMG_20200831_101503The removable Teak floors inside the Heads and Showers have moved on to their next stage of completion with the Black joining compound now all sanded down to a flush surface and are now ready for their fiberglass bottoms to be applied.

ELECTRICAL PROGRESS:

Hilmi our one and only “Sparkie” or Electrician continues to make steady progress with all things electrical onboard Möbius which covers a LOT of different aspects from lights you see above to cabling, connections, circuit breakers, switches, controls and other electrical devices ……………

IMG_20200902_100721………. such as this UDST 800 Ultrasonic Depth/Temperature/Speed transducer in the Bow.  As you may recall seeing last week this transducer is installed inside an otherwise unused integral tank in the hull so that in the unlikely event that we somehow managed to scrape the whole transducer off the maximum amount of water we could take on would be small and self contained within this WT compartment.
IMG_20200902_100735Hilmi has now installed the N2K cable from the transducer up out of the WT compartment through this cable gland which keeps the tank fully watertight.
IMG_20200831_101954Up in one of the highest spots on Möbius, Hilmi has all these MC-4 connectors installed in SkyBridge roof for each of the eight 320kW solar panels that form the roof as well as the other six solar panels fore and aft of this.  In addition to a fully sealed twist lock connector, we use this model that contains a 15A fuse inside which can be easily replaced with a simple twist.
IMG_20200831_102003All the wiring in the SkyBridge roof is now installed in these two cable trays that run down each side of the center rectangular AL extrusion that forms the ridge of the roof and then travels down the inside of the Main Arch tubes to make their way down to their connections to the 14 Victron 100/20 SmartSolar MPPT controllers in the Basement.
IMG_20200902_122534One last bit of electrical detail for those interested are these Swiss made Belimo 24V vent air damper activators.  These connect to a set of louvers inside the Vent Box and Open/Close them as required.  They are normally closed until they are activated as part of the start up sequence for Mr. Gee, our main engine, and allow fresh air in through the Port side Vent Box and extract it back out through the Starboard side Vent.
IMG_20200902_122540The dampers are also part of the Automated Fire Extinguishing System which would immediately close off all these vents and shut down Mr. Gee so that the aerosol Fire Extinguishing gas stays trapped inside the Engine Room with no air able to enter or leave and the fire can be quickly extinguished.  This heat activated sensor adds an additional level of Safety if the FFE does not work by closing the louvers anytime it senses a temperature higher than 72C/160F.  There is also a manual crank that you can use to close/open the louvers at any time in case of an electrical failure.

Fire is probably the scariest thing aboard a boat so we take it VERY seriously and take no shortcuts to ensure that we are alerted as early as possible  to any rise in temperature, any smoke or gas or heat and can take action immediately as needed.

AFT SOLAR PANEL BANK:

Light of a different kind or at least purpose was also the focus this week as Uğur and Nihat, along with our student intern “Omer” from Istanbul Tech University, took time away from building the Tender to Möbius to build the racks and mount the three 320kW solar panels that mount on the cantilevered roof above the Aft Deck Galley.


Fwd Stbd SkyBridgeWe have 14 solar panels in total which are in Purple in this quick render.  3 on the angled & hinged frame overtop of the Pilot House, 8 which form the roof over the SkyBridge and 3 on the Aft Roof.

Total Solar Wp (peak watts) is about 4.5kWp and each panel is wired to its own Victron 100/20 MPPT controllers in the Basement.
IMG_20200901_170836As always we did our best to KISS or Keep It Safe & Simple, the design of these racks to mount the three Solar Panels.  Four lengths of 30mm / 1” aluminium L-bar with mitred corners.
IMG_20200903_165554It took Nihat minutes to cut, fit and weld these frames and then he and Omer tested them with the actual solar panels to make sure it all fit just right.
IMG_20200904_140747With the solar panels removed the three frames were easy to lift up onto the roof where they were tacked together with the center panel offset Aft to match the angled end of the roof and reduce shading from the Main Arch and Paravane A-Frames in front.
IMG_20200904_170545To make it easy to attach and remove the solar panels, these short lengths of 50mm/2” L-bar were welded to the roof and matched up with same size L-bar brackets around the edges of the Frames which can then be easily through bolted to the brackets on the roof.
IMG_20200904_170503This enables the solar panels to be through bolted to each Frame and L-bar bracket when they are standing up and their underside is easily accessed.  Then the assembled Panel + Frame assembly can be bolted to the roof brackets.


IMG_20200904_170609As you saw earlier, the + and – cables hard wired to each Solar Panel have a standard MC-4 twist lock connectors.  I had purchased the matching MC-4 connectors wtih built in 15A fuses and the crimping tools for these which Hilmi is using here to make quick work of installing these MC-4 connectors on each cable that will carry the output from each Solar Panel down to the Basement where they connect to their dedicated Victron 100/20 SmartSolar MPPT controllers.
IMG_20200904_183114Hilmi worked hand in hand with the Framing team to have them mount this cable tray to safely carry the six cables from the Solar Panels over to the cable penetration they welded into the roof.
IMG_20200904_183123Where the cables are then fed over through the penetration into the interior of the Pilot House where they get routed down into the bank of 14 MPPT controllers in the Basement in an uninterrupted run.
MVIMG_20200904_170529All three Solar Panels now bolted securely into their frames, wires routed on their underside and ready to be carefully laid down onto the awaiting brackets on the roof.
MVIMG_20200904_183035Like this!

All the other 11 Solar Panels have been fully mounted and connected to their MPPT controllers so these three now complete the Solar Panel installation and all 14 MPPT controllers have their indicator lights blinking away.

Well done Team!

TENDER BUILD CONTINUES


Tender JetDrive 009 overall render

Picking up where we left off last week, Uğur and Nihat make more swift progress on building the Tender to Möbius this week.  You seem to be enjoying the rapid fire series of photos as this Tender takes shape so I’ll do the same this week and run through a chronological series of photos so you can watch the Tender come to life.

IMG_20200831_163148Here is where the Tender was on Monday morning.  Hull plates all tacked in place along with some internal framing and the start of the offset center console.
IMG_20200831_101118Seats which double as fuel tanks wrap around the Bow on the Right and upper angled section of the Console in the Left foreground.  Floor framing and hull plates below.
IMG_20200831_101031Console on the Right, seat behind and “Engine Room” as Uğur likes to jokingly call it at the aft end.

IMG_20200901_121814Raised Bow pulpit shaping up.  We wanted to have a wide flat area on the bow to make it easy to board with the bow pressed against a dock of the transom of Möbius. 


See the Tender render above to see the whole upper perimeter will have a dense tough foam Fender about 250mm/ 10” wide attached which makes the flat at the Bow even wider and good for being a mini tugboat to push other boats or be the auxiliary power for Möbius in an emergency.


IMG_20200901_12330920mm/ 3/4” thick Transom plate tacked in place now. 

Note the etched lines with the “Mickey Mouse” ears which will be CNC cut out later.
3123In addition to this cut out in the transom, the cast aluminium frame in Blue here is supplied by Castoldi and will be welded into the bottom of the hull plates to create the opening where the Castoldi 224DD jet drive will slide in and be bolted in place.
Castoldi 224DDYou can see how the cast AL body of the Castoldi 224DD on the Right will fit into the frame in the bottom of the hull and how the thick vertical plate in the middle will through bolt to the Transom plate.
IMG_20200901_123359Partially wrapped in bubble wrap from the factory, this is what that cast AL frame looks like.

The three cross bars are temporary braces to keep the frame fully aligned while it is welded into the hull and then these will be cut out and the Castoldi jet drive slid in place and through bolted to this frame.

OK, quitting time on Friday so we will pick up from here in next week’s Progress Update.

Hope you enjoyed this rapid fire Tender Build sequence.

STARTING Mr. GEE – TWICE!

IMG_20200831_152406No not quite ready for his first real start up, but I did get time this week to finish rebuilding his 24V electric starter motor.

This is a new set of clutch plates which lock the starter gear to the motor shaft as it slides forward to engage with the big ring gear on the flywheel and spin Mr. Gee to start.
IMG_20200831_165653This is the working end of the starter; the bronze starter gear that engages with the ring gear on the flywheel.
IMG_20200831_200422A quick visit with the sandblaster and two coats of epoxy primer have the starter ready for its final paint job.
IMG_20200901_164031In shiny Black.
IMG_20200901_164047However the start of the starter show IMHO are these bits and bobs which have also been blasted, primed and finish coated with Black epoxy and will soon be assembled into the Hand Cranking starter for Mr. Gee.

Hand Crank lever is in the middle here.
IMG_20200901_164051This chain drive gear uses the lever at the top to engage with a slotted drive gear on the crankshaft such that when you turn the hand crank handle the crankshaft spins.  With the compression release holding all six intake valves open you can get the giant flywheel up to speed, flip the compression release levers off and Womp – WOmp – WOMP, Mr. Gee comes to life!
And I can’t wait to show all ye with so little faith, just how this works in the video I will shoot for the first start-up with both the electric and the hand crank start.

So don’t touch that dial!  Stay tuned here for the next episode of “As Mr. Gee Turns”

Thanks for joining us and see you again next week.
