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.
Lots 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.
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.
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.
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.
Whereas 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.
Serkan, 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.
I’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.
Hakan 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.
In 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.
Whereas 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.
In 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.
The 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.
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 ……………
………. 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.
Hilmi 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.
Up 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.
All 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.
One 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.
The 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.
We 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.
As 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.
It 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.
With 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.
To 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.
This 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.
As 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.
Hilmi 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.
Where 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.
All 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.
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
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.
Here 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.
Seats 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.
Console on the Right, seat behind and “Engine Room” as Uğur likes to jokingly call it at the aft end.
Uğur, checking out the visibility when seated at the Console. He gave it his thumbs up.
Raised 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.
20mm/ 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.
In 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.
You 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.
Partially 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.
20mm / .75” thick engine bed plates tacked up.
Pulling the two upper hull plates into position to create the Bow.
Upper Hull side plates being led Aft and tacked in place. Flat bar tacked below to set the curve of this joint.
Scrap bits of AL tacked across the hull plate joint to keep it flush while tacking both in place.
Working in Tandem, Nihat presses the two plates into alignment as Uğur moves along with his MIG gun tacking the two plates together.
All tacked up and ready to be fully welded once some of the internal frames are set in place.
Bow all tacked up.
Nihat cleans up the welds before the Bow is welded closed with the top plate.
Stepping back to see that the Tender is shaping up nicely.
Tack – Tack –Tack.
Bow is ready for welding.
Tack – Tack –Tack.
Sides and bulwark tops are all in place.
Integral floor framing added in next.
Starting to look like a boat!
Uğur spends the better part of a whole day laying down the final welds of all those tacked up plates.
Working on his Ninja Warrior Welder look, Uğur cleans up one of the Engine Beds he has welded up and is ready to be welded into the Hull.
Inside of Hull plates finish welded as is the lower strake and the frames for the floors and the sides of the Engine Bay.
Floor plates in the Bow seating area lay down quickly along with those leading along the walkway on the Port/Left side of the Tender.
Inner side plates now ready to be installed and the Console seat box is tacked up.
Captain Christine is called over for a test fit when she is piloting the Tender while seated at the Console.
The Captain is happy with both so the work can proceed!
Console and seat is emerging.
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!
No 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.
This is the working end of the starter; the bronze starter gear that engages with the ring gear on the flywheel.
A quick visit with the sandblaster and two coats of epoxy primer have the starter ready for its final paint job.
In shiny Black.
However 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.
This 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.
A full five day work week here for everyone but me it seems as I had mine cut down by almost 2 days while I looked after a hernia that I developed on my Left side last week. Nothing too serious, I had one on my Right side about 25 years ago and apparently my body wanted to keep all my internals symmetrical so time to fix the Left side this week.
WARNING: This week’s intro may be TMI as my children used to often say; “Too Much Information” Dad!, so you are welcome to skip down to the next section below if you prefer.
The medical system here in Turkey is absolutely awemazing, easily amongst the best anywhere in the world and so after a few visits for ultrasound and other testing they did the laparoscopic or “keyhole” type surgery on Monday morning and I was released Tuesday noon and was able to stop in to see how things were going on XPM78-01 Möbius before heading home to rest for the rest of the day.
They ended up needing to put in a 10cm x 25cm (4” x 10”) strip of hernia mesh material which was much larger than they had originally thought because they decided to cover both my Left and Right sides for a more “future proof” reinforcement.
This required three different entry points for the laparoscopes so I ended up with three neat little “bullet wound” looking spots across my lower abdomen which should be fun for future wild tales from Grampa Wayne in the future.
Hence the double meaning of “tender” for this week’s Progress Update as it applies to my condition this week and MUCH more importantly the beginning of the build of the Tender to mv Möbius!
Best of all however is that I’m feeling much less Tender every day and the Tender to Möbius is feeling more and more real by the day.
So let’s jump right into this week’s Show & Tell of the overall progress on XPM78-01 Möbius for this week of August 24 to 29, 2020.
TENDER to “my Möbius” (my = motor yacht)
First for some perspective, here are the basic details for the Tender:
- Length: 5 meters,
- Beam: 1.8 meters.
- Material: Aluminium 5083 series,H Series, H321.
- Powered by internal 110HP/81kW Yanmar 4JH4 HTE diesel engine with direct manual fuel injection
- Castoldi Jet Drive 224 DD (Direct Drive)
- Central steering station with sloped dash area large enough for small navigation equipment, display screen, switches, gauges, etc.
- Twin side by side seats at steering station.
- Additional seats for minimum of 2 other adults, ideally 4
- Built in lockers sufficient in number and size to hold typical items including life vests, fire extinguisher, spare plastic fuel jugs
- Diesel fuel tank integral with hull, 80-100 L capacity
- Equipped with full cover such that the Tender can be used as the boat’s life raft.
- Designed to withstand ocean going conditions with waves up to 4m and wind up to 8 beaufort.
- Engine and propeller system will be owner supplied, small likely 3 cylinder diesel with fixed prop.
- Tender will have large continuous “bumper” wrapping around both sides and bow sufficiently strong to allow using these Tender to push Möbius and other boats and resist abrasion from rough docks, rocks, etc.
- Foam collar will be adhered to a custom built recess in the hull for this foam bumper and have a wide flat section across the Bow for pushing.
- Build in support bars on both side of the flat Bow for safety when boarding from the Bow
- Swim Step overtop of extruding Jet Drive to fully protect the drive gear when backed into docks, rocks, etc.
Here is what those specs and use case look like when transformed into the final 3D model after many months of working with Yigit and Burak.
We also worked with the engineers at Yamaha and Castoldi who helped get the hull shape, dimensions and weight distribution just right.
The Castoldi Jet Drive 224 DD (Direct Drive) …….
…… is coupled to the Yanmar 110HP/81kW
Yanmar 4JH4 HTE diesel engine using a Cardan shaft and a Centaflex flexible coupling.
We think this combination will make for an eXtremely safe, fast, fun and dry ride!
You may recall seeing in last week’s Progress Update that all the CNC cut plate for building the Tender to my Möbius had arrived and first thing Monday morning Uğur started sending me pictures of he and Nihat tearing into that stack of aluminium and starting to assemble all those CNC cut jigsaw puzzle pieces.
Similar to the building of the Möbius herself, this process of assembling precisely cut, numbered and interlocking pieces to build an aluminium hull boat is very similar to assembling a jigsaw puzzle or plastic model airplane kit. As you can see if you look closely (click to enlarge any photo) the CNC cutter is programmed to leave tiny little “bridges” or tabs every so often along the through cuts so that the individual pieces stay part of the whole sheet of aluminium so they can be shipped/trucked very efficiently.
I received a lot of comments from last week’s posting of how much you enjoyed seeing the Davit go together so sequentially so I will do the same below with the Tender by quickly going through photos as the build progresses quickly with a bit of explanatory text along they way. Ready – Set – GO!
Nihat likes to start by wire wheeling all the surfaces to remove the aluminium oxide layer and provide a super clean surface to weld to.
Next he uses a cutting disk in an angle grinder to sever all the little tabs and remove each individually numbered piece from the sheet.
He sorts all the pieces into stacks of similar pieces such as this pallet with all the Deck/Flooring plates.
Thursday morning, Aug 27th, the real fun begins as they start the kit building process by laying the three bottom hull plates on the floor and tacking the vertical frames in place which starts to pull the hull plates into the exactly correct angles.
To shape the more complex curved bow, we used an Origami boat building technique which our Rhino 3D modeling software makes very easy. This process begins by creating a 3D model in Rhino (thanks Yigit and Burak!), and you refine the shape of the model using hydrodynamic testing to come up with the Goldilocks or Just Right shapes and angles for the use case the hull will operate within. Then Rhino3D has a “Flatten” function that creates the paths for curved CNC cuts.
In this photo you can see the first Starboard/Right side hull plate laying flat awaiting the Port/Left plate to join the party.
Captain Christine joins Omer & Uğur to get a sense of the shape and scale of our new Tender.
Aluminium bars are tacked in place to provide temporary attachment points for the chain tackle to pull the curved cuts into contact with each other.
This proceeds in stages, welding the plates where they touch as you work your way forward.
Uğur ‘s keen eye is constantly checking as he pulls the two halves together to ensure that everything stays perfectly aligned as he welds the seam to join the two plates into the finished bow.
To assist with keeping all these compound curves all aligned with each other they have also now tacked the two strake plates to the top outer edges of each hull plate. This strake helps the water flow both lengthwise and sideways to deflect the bow wave off to the side rather than up the hull and onto those of us aboard.
Similar process is used to now add the next row of hull side plates and pull them into alignment with the lower plates and strakes and tack them in place as the build continues.
View from the top makes it easy to see how this all comes together.
With the Bow end tacked in place Nihat and Uğur clamp the rest of these side hull plates into position and …………
………………… tack them along the whole length of the hull like this.
Looking at the stern from about the waterline level you can see the profile shape of the hull which is what a jet drive boat wants. Also makes for eXtremely small Draft so we can travel through very shallow waters with no damage to the coral and nature below or to the hull.
Integral fuel tank has three sections, one on each side which flow into the deeper compartment on center in front. The very front bow compartment will be for storage of things like anchor & chain.
Nihat starts adding in the frames inside each tank and tacking those in place.
First frame of the center console being fitted. This will have monitors on the upper sloped surface with controls and steering wheel below and double seat aft. There will also be an acrylic windshield extending above the top of the AL console for added wind and water protection for the pilot.
Port side console frame helps to fill in the overall shape and size of the console which is asymmetrically positioned to extend all the way over to the Starboard/Right side hull at the bottom of this photo and leave a walkway on the opposite Port/left side.
Uğur and Nihat are a great team so the Tender progresses quickly as Nihat tacks the pieces in place and Uğur follows behind doing all the finish welding.
Still lots of jigsaw puzzle pieces to be added!
Omur our student intern from Istanbul Technical Institute helps out by holding this upper coaming plate vertical for Nihat to smooth the curved edges from where they were attached to the CNC cut plat originally.
Console all tacked up as is the framing for the Floor/Deck plates fore and aft of the console and under the seat base.
Just for a test fit right now this inner side plate will wait for the internal welding to be completed before being slid into place and welded to the hull.
Burak kindly plotted some larger scale 2D drawings and shots of the model which Uğur has mounted on this board beside the Tender with Möbius looing on from behind.
25mm / 1” thick AL Engine Bed plates being test fit on either side of the “Engine Room” area aft.
Up near the Bow, Nihat has the one piece top deck plate ready for Uğur to weld in place. As with the main hull of Möbius slot welding is used to weld AL plate to the frames that are inaccessible underneath.
As we have been doing most weeks, we are working on Saturdays to try to make more progress so this is where the Tender build was at when we finished the day yesterday.
Did I mention that day time temps are running 34-38C / 93-100F? Add all the heat from the MIG welder and you have three VERY wet Tender Builders! Uğur takes a well deserved pause to survey the days work and let the air blow over him from one of two big squirrel cage fans we have setup to blow air across the Tender.
I hope you enjoyed this whirlwind tour of the past three days and this photo is how the Tender build looks at quitting time yesterday. Tune in again next week and I’ll walk you through the rest of the build of the Tender to my Möbius.
DAVIT ARCH BUILD:
Lest you think that the Tender was all that Nihat and Uğur worked on this past week, they also finished building the hinged Davit Arch that we will use to move the Tender On/Off Möbius’ Aft Deck.
This is the first test fitting of the three individual segments that make up the Davit Arch. Two vertical legs on each side which are bolted to the horizontal cross beam above.
One of the vertical legs on the Upper Left here and the upside down cross beam on the Right.
For added strength these additional 25mm/1” plates will span the connection between the horizontal beam and the short angled pipes that connect this to the vertical Arch legs.
Uğur quickly has them fully welded with multiple passes of his MIG gun.
The plate spanning the two braces will also provide two addition attachment points for the 6:1 blocks and Dyneema the Tender will be suspended from.
Now time to build the two Hinged Base assemblies where the bottom legs of the Davit Arch connect to the Aft Deck.
Two of these 25mm/1” thick base plates will attach to the Aft Deck and support the large Hinges. These two triangular vertical plated form the outer sides of the hinge with the 50mm/2” SS hinge pin fastened in between.
Due to the camber of the Aft Deck and the different offset from the boat’s centerline, the two hinges are at different heights above the deck.
These two very thick tubes are the third part of hinge and will be machined to slide between the two vertical triangular pieces above.
These tubes will be inserted into these large holes in the bottom of each Arch leg where they will captured between the two plates on the Base and rotate on the SS hinge pins that slide through all three parts of the hinge.
Stay tuned for mounting this to the Aft Deck and testing it out in the next week or two.
Mr. Gee Gets All Glossy
With my shortened week I didn’t get as much time to work on Mr. Gee but I was able to do some more painting and clear coating on Saturday including a good clear polyurethane coating of this aluminium beauty. This is the rarely seen back side of the massive fuel inject pumps and governor assembly that bolts to the Port/Left side of Mr. Gee.
Sorry for the poor lighting but this is the side you see and where all the action happens with the fuel injection system. The six vertical levers for example are what you pull to prime each cylinder and the high pressure injection pumps are located right behind them.
Burgundy part in the foreground is bolted to the flange above it and pumps engine oil through that massive solid Bronze oil cooler/heat exchanger on the other side of Mr. Gee that you’ve seen me rebuilding in previous postings.
These instructions are cast into the large aluminium Header Tank at the front of Mr. Gee which is like the plastic bottle on your car’s engine where you check and add anti-freeze/water.
I’ve painted these with matching Burgundy and next week I will polish off the tops of the letters to make them a bit easier to read and add a bit more class to Mr. Gee.
Same thing will happen to the instructions cast into this timing chain adjuster lever.
And these cover plates which bolt to the sides of the cylinder heads.
Mr. Gee’s Best Buddy; Nogva CPP
You might think that Captain Christine is “just” the Captain, she was also called up for our all hands on deck work schedule and spent two very hot days cleaning, sanding and masking the Nogva CPP Servo Gearbox that will soon be bolted to the back of Mr. Gee.
Mr. CPP may be small but he is mighty and provides the 2.95:1 gear reduction to Mr. Gee’s already slow spinning crankshaft.
With a CPP, Controllable Pitch Propeller, we don’t have a transmission per se as we go from forward to reverse by simply changing the pitch angle of the four prop blades.
It is called a Servo because it also houses the hydraulic controls that move the Pitch adjusting rod that runs down the center of the prop shaft where it connects to each prop bladed inside the hub of the prop and rotates the four prop blades in unison to whatever angle of pitch we want.
A VERY cool bit of kit BUT we can’t have his Nogva Red clashing with Mr. Gee’s Gardner Burgundy now can we?? So a new paint job was required and hence the big cleanup and sanding this week.
Uğur kindly helped move the Nogva to the far corner of the shipyard near where they are building the Tender so I could paint it there with the big shop doors open.
Nogva smartly provided a purpose built lifting eye that is centered on the weight of the CPP so we used that to suspend it from the forklift which made it real easy to paint with no supports in the way.
Christine had done a great job of cleaning and sanding as well as masking off all the rubber hoses, pressure and oil level gauges and al the instruction and labeling plates riveted to the case which made my job of painting him very quick and easy.
At least until THIS creepy single hander guy showed up!
Between us though, we soon had Mr. CPP ** resplendent in his matching Gardner Burgundy coat and ready to be lifted aboard Möbius and bolted up to the anxiously awaiting Mr. Gee next week.
** If anyone has a better suggestion for a name for Mr. Gee’s best buddy and our CPP, please add it below in a comment.
FRIDGE & FREEZER INSTALLATION
If you were with us last week you saw the initial fitting of the two 130L Door style Fridges in their Ro$ewood cabinets on the Left and the two 70L Drawer freezers on the Right.
Monday morning the refrigeration team returned to charge all the compressors with their respective refrigerant; Freezers with R290 and the two Fridges with R134A. The reason for the different gasses is that the Drawer Freezers are a brand new model from Vitrifrigo and they have changed to using R290 which is a friendlier and more efficient refrigerant than the much older R134A standard in most compressors. However it is not possible to mix the two or simply change refrigerant so we have to stay with using two different refrigerants. Not that big a deal just means I need to carry a supply of each onboard to use with my vacuum pump whenever a need to fix and recharge the compressors might happen in the future.
Down in the Basement, directly below the Fridge/Freezer cabinets the four 24V Danfoss/Secop compressors are now fully mounted and recharged. We ran them for a day and pulled them down to their lowest temperature settings and they all passed with flying colours. Christine and I can hardly wait to be filling these with provisions when we get ready for our Maiden passage.
SPARKS CONTINUE to FLY ABOARD Möbius
Hilmi our head “Sparkie” aka Electrician was about the only one left of Team Möbius to be working onboard this week but he was his usual busy self and persevered by powering through his still quite lengthy list of electrical jobs needing to be done before we can launch.
Interior Lighting is one of those lists and that is nearing completion as evidenced by all this bright “stars” above the SuperSalon. Each one is a fully dimmable LED so in addition to having eXtremely low amp draw they also allow us to fully control the amount of light in each space.
Each LED looks the same on the outside for esthetics but they are all different on the inside for their different purposes. Some such as these task lights in the Galley are bright White and higher Lumens so the Chef always has just the right lighting when working in the Galley. Other locations of warmer light and lower Lumens to best suit the activities there.
More exciting lighting up in the SkyBridge this week as Hilmi mounted and wired the LED light bars on the “ceiling” up there. Christine and I are still debating how best to finish off these surfaces of the undersides of the eight solar panels that form the roof/ceiling of the SkyBridge.
Our top priority is to keep a good cool air flow over the undersides of all the solar panels to remove the heat they generate as as heat reduces the efficiency and output of a solar panel to an eXtreme degree. However we also want this ceiling area to be attractive and in keeping with the style and esthetics of the rest of Möbius so we are pondering different ways to do this. For now however and to keep things moving forward as fast as possible we will leave this ceiling as is and go with the “industrial’ and fully functional look that is very much in keeping with the exterior of Möbius.
Hilmi has installed these 50mm/2” wire trays down both sides of the center “ridge” extrusion and is also using these to hold the MC4 solar connectors.
We took the KISS Keep It Safe & Simple and I believe more efficient approach to fusing each solar panel by using these MC4 solar twist lock connectors which also have 15A fuses inside them. No extra wiring, no fuse box, easy to access, what’s not to like?
Speaking of Industrial and Fully Functional, Hilmi finished off the installation of these goodies on the inside frame of the big AL hatch into the Forepeak.
The box on the far Left has the plug in for the hand held remote control for the Maxwell Windlass which is hiding under the cardboard box on the Left and this handheld remote will normally be in the holder on the Right.
The large Blue receptacle is where the Forward Shore Power Cord plugs in and the box on the far Right has the requisite RCCB or Residual Current Circuit Breaker.
The traditional marine “Twist & Lock” shore power plugs like this one used in North America are an abysmal design IMHO.
Quite frankly they “spark” great fear in me given how poor their electrical connections between the plug blades and the socket receptacles are. Poor connections create resistance which creates heat and leads to these plugs literally burning out on almost every boat I know. I strongly suspect these Twist & Lock shore power plugs cause more boat fires than we will ever know.
In any case they are forbidden on our boat and we instead use these CEE style plugs which have three round solid brass rods.
For marinas which only have the Twist Lock style we carry adapters like these to adapt our CEE Blue plugs to the Twist Lock style AND these say ON THE DOCK and not on our boat!
Our 220V @ 32A Shore Power cords plug into the boat at either this plug in inside the Forepeak …………..
…….. Or this one in the Aft end of the Workshop by the WT door from the Swim Platform.
These RCCP Residual Current Circuit Breakers or ELCI Equipment Leakage Circuit Interrupter are now required on all CE/ABYC compliant boats.
These are very important safety devices which provide whole boat protection similar to what the GFCI circuit breakers you have, or should have, on the 120/220V plugs in bathrooms and kitchens.
We are using Schneider for all our AC electrical equipment and this is the RCCB we are using which must be located immediately after the Shore Power entry into the boat, hence one in the Forepeak and one in the Workshop.
One last round of exciting work from our Sparkie Hilmi is the installation of the ultrasonic Depth/Speed/Temp “triducer”. This is our last, I hope, open hole (purposeful) on Möbius so we are now fully water tight. Yeah!!!
The Airmar UDST 800 is a relatively new technology for measuring Depth, speed through the water and sea temperature.
See video at the link above for a quick easy demo.
The eXtremely welcome innovation is that the speed sensor has no moving parts such as the paddlewheels we’ve had to use on all previous boats which last for just hours sometimes before they foul with marine growth and stop working.
By using an Ultrasonic sensor the UDST 800 has just a smooth glass surface in the water which will rarely foul and is easily cleaned ever few months with a quick wipe.
I chose the location for this forward depth transducer, we have a much more powerful and bottom discriminating sensor Aft, so that it would be inside this otherwise unused integral tank. If you peer down into the open access hatch (click to enlarge) you an see the AL pipe welded into the bottom hull plated and now the Black plastic outer housing is in place where the UDST 800 will be inserted from up here inside the Forepeak.
Why here? Well, if we should ever have a serious grounding of the bow or a collision that managed to clean off the flush transducer, however unlikely, it means that the most water we can take on is what would fill this relatively small WT compartment.
Close up of the plastic housing with its very clever self closing flapper valve which allows you to pull the transducer up and out while still in the water and it will close off the gusher of water wanting to pour in while you push the blanking plug in place while you clean or maintain the UDST 800 at your leisure inside the Forepeak.
We were very disappointed and saddened to find out while I was in the hospital that Omur, who has been our Lead Cabinetmaker for the entire interior build on Möbius the past two years, is no longer working at Naval. However his craftsmanship lives on and before he left he was able to finish off the matching Rosewood drawer and door fronts in the Galley such as this bank of drawers on the peninsula by the Entryway door.
Even surrounded by all the protective covering you can get a sense of the quality of Ömür’s work and how he prided himself in always being able to find the Goldilocks Just Right combination of matching grain patterns.
I have learned in my short life so far that it is the little things in life that often make the big differences and these beautiful solid SS latches is one of my favorite examples onboard Möbius.
Richard, one of our faithful followers, was instrumental in helping me track down the producer of these lovely latches that I had seen several years previous but could not find again.
Trying out a test mount in a scrap of plywood, you can see the nice big solid SS latch hook on the inside.
On the upper inside framing around each drawer the matching SS latch plate could not be simpler or easier to install like this.
Here is how they look when mounted in our drawers.
To operate you just hook your finger under the lower edge,
Gently lift up against the built in spring pressure to release the latch and the drawer slides out effortlessly on the SS ball bearing Blum drawer slides hidden away below the drawer bottom.
When you have gotten what you needed out of the drawer a gentle push slides the drawer back into its closed position with the automatic soft close feature of these Blum drawer slides and the drawer is again solidly latched in place. No forgetting to lock them before you head out to sea or some passing boat’s bow wave sets you rockin’ and the drawers all slide out.
More features we can’t wait to start living with aboard the Good Ship Möbius.
And with that, I shall bid you adieu for this week and go rest my still somewhat tender little body for the rest of this Sunday evening. I go back to the hospital tomorrow morning for a checkup and to remove the bandages and then I should be all good to go and be fully recharged and ready for the final push to finish Möbius and get her launched ASAP.
