Everything continues to heat up here at Naval Yachts with hot +40C summer days and lots more progress with the building of XPM78-01 Möbius. Onboard Möbius the Cabinetry team, Aluminium team and the Plumbing team continued from where we left off last week and in the Engineering/Design office lots of progress with Interior Design work, choosing materials and working out construction details and 2D drawings. Welcome aboard and let’s go check it all out.
Let’s start in up front with the work on the Head/Toilet and Shower in the Master Cabin with some quick renders from our awemazing Interior Designer Yesim. This is what you’ll see when standing beside the bed just after entering the Master Cabin. The two outer walls of the shower are solid glass and will be etched with an artistic pattern our talented and dear friend Sherry is busy designing for us. Cupboards for clothes, washer/dryer are on the Starboard/Right side which you’ve seen being built in previous posts and this week the Vanity Sink at the far end was completed.
Seen from above with the deck removed you can see a bit more detail such as the two big hatches above the Vanity and the Shower, the seat in the shower and the sink in the Head area. We are going with an open walk through into the shower with a clear glass panel going up from the sink counter to just below the hatch opening to allow air and light into both the Head and the Shower areas. Removing the door and the wall beside the Vanity sink gives us a better view of this whole space. There will be a “shower tower” diagonally mounted in the far corner of the shower and the seat will be done in either teak or rosewood. In the Head there is an iridescent blue/black countertop mounted sink to match the one in the Vanity with hers/his mirrored medicine cabinets in the side wall and the VacuFlush toilet/bidet on the far right. All the interior walls, ceiling and floor of this whole space will be built in place using fiberglass panels and hand laid cloth to make the whole unit fully sealed with no joints. Production boats and homes would make this as one piece in a mold and then lift it in place in the boat before the deck goes on. However as with all the interior cabinetry we wanted to bring all the interior components into the already welded up boat and fasten it all solidly to the aluminium frames and stringers.
Christine is busy hunting down some tiles to add a bit of colour and style to the interior and check out the sinks she found for here and in the Vanity. This rectangular one will go on the counter in the Head.
And this oval shaped one will go in the Vanity.
These are very unique sinks made from solid tempered glass that is about 20mm/ 3/4” thick with hand painted patterns on the outer surfaces with great depth and sparkle when seen from above. Matched up with our aquamarine colour scheme for things like the Horizon Line throughout the boat and 1seemed like the Goldilocks just right, just for us sinks. Back onboard this is about where we left off last week when Omur and Selim had the Vanity Sink cabinet roughed in place and the first wall of the Head/Bathroom positioned. This is where the oval glass sink above will be mounted. Matching cabinetry details throughout with these Horizon Line/Hand holds and well radiused edges on all the solid Rosewood. Back in the Cabinetry shop Ömür is putting together the medicine cabinet that will be mounted above the Vanity Sink. Dado/groove you see in the bottom edge for the LED indirect lighting. Ömür’s ever focused eye checking out the inner details before taking this onboard Möbius …… …… to fit it in place up against the Forepeak WT Bulkhead. The white epoxy painted grid in the background is affixed to the aluminium plate of the WT Bulkhead with epoxy painted wood blocks and provides the foundation for the cabinets such as this Medicine Cabinet to be screwed in place for now. With the Head wall removed you can see how the Vanity Sink cabinetry ties into the Starboard side cabinetry and how the overhead hatch will really light up this area. Yesim and Harken (middle) our gifted 2D cabinetry drawing wizard join Ömür and myself onboard to go over the many intricate details for this busy space with plumbing, wiring, cabinetry, doors, in floor heating, drains, water supply, fuel tank access and the list goes on. Every day is filled with hundreds of such details and decisions which keep all of us on our toes and at the top of our game. Here for example we are confirming the location of the hollow channel inside the door jamb in the foreground where the wiring will come down to the light switches below Harken’s elbow.
(for those wondering, my hand is the upper left to keep out the lens flare from the big hatch over the Shower.) With those details worked out for now Ömür screws the marine plywood backing that form the end wall of the Head. A similar construction will take place next week on the hull side walls and then all these plywood surfaces will be laminated with fiberglass sheets to form the continuous walls, floors and ceiling surfaces. Ömür and Selim move their attention to the aft Port corner of the Master Cabin and starts to attach more of those solid wood blocks to the aluminium plate behind the white acoustic foam insulation.
Next day when the adhesive has cured the grid framework can be screwed in place. Zooming in closer you can see how the grids are constructed with tongue and groove for the triangular braces and keeping this gridwork all eXtremely light yet strong. When the plywood panels are mounted on top of the grid it will create another layer of insulation of trapped air…… …….. that will sit atop the three layers of varying density acoustic insulation you can make out under my thumb. If you look closely (click to enlarge any photo) you can see the thin dark gray middle layer sandwiched between the black foam laying against the aluminium bulkhead plate and the thick white outer layer.
On the other side of the aluminium plate inside the Basement is yet another layer of 50mm / 2” thick EPDM foam. Can you tell I’m just a wee bit fussy about building eXtremely quite boats??!!
Just before we leave the Cabinetry team lets go back to the Cabinetry shop and meet the newest team member, Ömer. Spelled with an E and not to be confused with Ömür, we find him busy working on the first of the cabinets for the Aft Guest Cabin. This will be the bookcase above Christine’s Office desk. Just before he put on the final frame board I was able to get this close up to show how the biscuits work to align and reinforce the solid Rosewood attachments to the laminated cabinet sides. These biscuits ensure everything lines up just right and then Ömer can clamp them while the glue dries like you see in the first photo above. Similar technique being used here to attach the solid rosewood edging around the perimeter of the door for the Head. In this case you can see how the wood wedges apply added pressure to push the solid edging against the laminated foam cored door. Next day Ömer has all the clamps off Christine’s bookcase. The middle shelf goes in to finish off the bookcase cabinet. The edge of this middle shelf will be painted with white polyurethane for some contrast so it is made from Birch rather than Rosewood. Heading back to the shipyard floor beside Möbius Uğur is busy prepping the intake sea chest that will go into the Starboard side of the Engine Room. The angled bottom end of this 120mm / 5” diameter by 10mm / 3/8” wall pipe will be welded to the bottom hull plates and bring fresh sea water up to the hole you can see here. There are two of these holes where the inlet pipes he is fabricating here will take sea water over to two strainers mounted on their ends. You can see a top view of all this in the drawing on the left with the top flange of the Sea Chest on the far left and then the two strainers on the right. Once he has all the pieces of pipe tacked in place Uğur takes the assembly onboard and fits it in place in the forward Starboard corner of the Engine Room.
The flanged top will have a Lexan cover bolted to it and sits well above the waterline making it easy to see if anything gets sucked inside. There is a threaded plug and a quick connect compressed air fitting in this cover so you can use either a broom stick or compressed air to quickly flush out any such intruder.
For the technically inquisitive in the shot above that is the 25mm /1” Starboard engine bed plate sloping aft at the bottom and the Starboard water tank sitting under the two sea water inlet pipes. The large opening is one of the access ports and the round SAE5 flanges with the SS studs are where the supply/return lines attach along with Maretron and Hart system tank level gauges and temp gauges.
The bottom flanges of two Vetus strainers will be mounted on top of those vertical pipe stubs on the right above and these will then feed into a manifold that supplies fresh sea water to things like the engine heat exchangers, water maker, wet exhaust, fire hose, salt water wash down pump and other such consumers.
Two strainers are used for redundancy and each pipe has a large ball valve on it with one open at all times to supply sea water to its strainer and the other one ready to be opened in an instant if the other is clogged or needs to be cleaned out. The black knobs make it easy to remove the lids of these strainers with no tools and have clear tops for quick visual inspection on each tour of the Engine Room which we do about every 1-2 hours when underway on long passages as part of our watch routine.
Standing up on the Aft Deck looking down through the big hatch into the Engine Room lets you see how this intake Sea Chest and strainers in the lower left corner will be setup. An exiting Sea Chest will be installed in the same position over on the right side bottom corner. Both of these Sea Chest tubes are coming up through Gray Water tanks which are seldom used but can be used to hold water from the Aft Cabin shower, Workshop sink and Aft Deck Outdoor Galley sink.
You can see the ER door on the angled corner of the ER Enclosure in the top right of this photo, the two thick engine beds running from top to bottom flanked by Water Tanks on either side. In the upper center you can see the long oval foil shape of the keel running down either side of the 25mm thick keel bar that runs the entire length of the hull.
Behind Uğur, Nihat has been working on the Day Tank, laying on its side here, and has welded in the 20mm thick plate you see on the bottom. This thickness is needed for the pipe threads that will soon be drilled and tapped for a series of 3/4” SS ball valves for the fuel lines bringing fuel into this Day Tank such as the return lines from the Gardner and supply lines from the fuel pumps that transfer fuel from one of the six integral fuel tanks. There are also a series of SAE5 flanges for Maretron and Hart tank level gauges. On the bottom is a sump to contain any water or contaminants that might somehow make it all the way to the Day Tank which is at the very end of our fuel polishing and filtration system. There is also a ball valve at the top and bottom of this Day Tank with a clear length of hose between to provide visual confirmation of the fuel level in this critical supply tank.
Never a dull moment for Nihat so he also looked after cutting in the air vent penetrations in the Aft Deck that come up into the two big Vent Boxes. The one he is cutting here pulls fresh air out of the Workshop and the one aft/right of that will be for extracting air out of the Engine Room. Techie Note; the ER vent is quite a bit larger than what you can see marked out here as you want to have the exhaust venting be about 120% greater than the intake to allow for the expansion of the air as it warms up in the ER and more so to ensure that there is a slight vacuum in the ER as the air exits to be sure that any fumes and smells are pulled out. Many boats don’t have this setup and their ER’s are slightly pressurized which tends to drive fumes into other areas of the boat. and tend to have higher engine room temps which can be very problematic.
Another job on the 2DO list for Uğur and Nihat was these vertical ends of the window frames that run atop the Wing Boxes on either side of the Aft Deck area. Here you can see that they have tacked a length of vertical flat bar and capped it with a matching length of 30mm / 1 1/4” pipe. This provides both a protective caps for the end edge of the 25mm thick glass windows and the pipe adds a sturdy vertical handhold that is in addition to the horizontal one above. Cihan was too much of a moving target this week for me to catch too many pictures of him but he and his plumbers continued to be very busy throughout the boat laying down hoses and pipes for various water lines such as bilge, potable, Gray, Black and Chiller along with fuel hoses.
These are potable water lines he is securing to the white perforated AL cable/hose trays. We didn’t put some of the frame penetrations into the 3D model until after the cut files were sent off to the aluminium supplier and CNC cutter because we wanted to make some of the hose layout and routing decisions later in the build. Additional penetration holes therefore needed to be cut into the frames and stringers for these new hose and pipe runs. While having these holes already CNC cut when all the AL parts first arrived is very nice, it doesn’t take too long to cut through the 10mm / 3/8” aluminium frame plates when you have great carbide tipped hole says like this! Like little mouse trails it wasn’t hard to see where Cihan and his helper had been this week with remnants such as these as telltale evidence. And that’s the week that was August 5-9 here at Naval Yachts as XPM78-01 continues to transform from virtual 3D models and renderings into the beautiful reality of aluminium and Rosewood. Hope you enjoyed this week’s progress update and thanks so much for taking time out of your busy day to join us.
The very big Eid al-Adha holiday began here today and runs from August 11 to 14th so everyone at Naval Yachts gets a well deserved four day holiday and the yard reopens on Thursday so just a 2 day work week next. I will be using the time to keep making progress on system designs, parts and equipment order lists and designing a few things like hatch closing mechanisms, alternator and water pump belt drive systems for the Gardner and so on. I will also try to write and post some of the more technical outlines and explanations of the various major systems such as Electrical, Battery and Charging systems, engine systems such as exhaust and cooling and so on. Stay tuned for those if you are interesting in diving into those details with me.
For most of my life I have strived to “put myself in the way of Beauty” and as the work on Möbius starts to branch into multiple materials from the aluminium of the hull to the copper of the electrical wiring to the rosewood of the interior cabinetry I find myself in the envious position of being immersed in beauty thanks to all the skilled people working all these materials into what I often refer to as “collaborative works of art and engineering”. Beauty is a feeling that comes through all of our senses, not just sight and if you come along with me for this week’s progress update tour and I think you’ll agree.
I will start our tour with the latest aluminium work; finishing the Lids for our in-house designed and built hatches.
Last week saw the CNC cut 10mm / 3/8” thick plates being welded to their 8mm thick flat bar frames so this week Uğur and Nihat ground those welded surfaces flat and flush …. …. and then polished the outer edges to a beautiful lustre, and the stack of polished hatch lids grew higher. These polished edges were then protected with blue masking tape and Mehmet cleaned up the inside corners which will be filled and sealed later with a cove of epoxy. Then the corners of he bottom edges were machined with a 4mm radius to round over this edge and make it feel as beautiful as it looks. Last step will be the tricky one of welding the Hinge Arms to these Lids and we’ll show you that next week. Several of you asked to see the jig I mentioned last week that Uğur and Nihat fabricated and used to tack the Hinge Boxes to the deck and outer Hatch Frame such that the holes for the SS Hinge pins were precisely aligned with each other and this is it. The two tabs on the jig slight snugly into each hinge box and the SS hinge pins are slid in place.
Using this jig, Uğur presses each Hinge Box up tight against the underside of the deck and the outside of the Hatch Frame and slides the SS hinge pin through the jib and boxes. This holds them in perfect alignment as he then tacks them in place. Viewed from up on deck here is what the finished Hinge Box looks like as it waits to receive the Hinge Arms of the completed Lids in a few weeks.
Which will look like this when done. The lids will have 15mm tempered glass adhered to them and there are two 20mm ID drains in the bottom “gutters” of the outer Hatch Frame (red here) to quickly remove any water that makes it down between the Lid and Frame. Down in the Engine Room/Workshop one additional aluminium detail has been looked after with the tacking up of the hinges on the Engine Room door which completes the Engine Room Enclosure construction and can now be fully insulated and lined with Alucaboard as it waits for the installation of the sea chests and ultimately the massive Gardner 6LXB engine and Nogva CPP propulsion system. Speaking of Mr. G as we refer to our mighty Gardner engine, several of you have asked for an update on his status which will have to wait for a bit longer I’m afraid. All the other aspects of the build have been consuming all my time to date, but I can give you this sneak peek and confirm that I am now busy with completing the full restoration of Mr. G to better than new condition. Thanks for your patience and stay tuned for MUCH more in the coming weeks I promise. Sticking with metal but changing to copper as in wires and cables, Hilmi our electrical lead continues to string wires throughout the boat, the latest being these gray ones which indicate that they are AC power lines which in this shot are crossing the ceiling of the Workshop and heading for those white cable trays to take them forward…… ……. to these wire trays in the Basement.
The loop of black 50mm / 2 fuel hose on two of the Fuel Fill/Vents into one of the six fuel tanks is exciting to see as this means they are pressure testing the latest round of work on the tanks and fuel plumbing. Such as installing the lids on all the many access ports on each tank. Same is happening for all six water tanks. All these SS studs will either be ground down flush with the tops of the nuts or have acorn nuts threaded on their ends for safety where they will be walked on. All this metal work is truly beautiful to this beholder but the newest source of beauty is over in the cabinetry workshop here at Naval Yachts so let’s head over there to fully immerse ourselves in this week’s beauty bath.
I don’t think you need to be a cabinetmaker to appreciate the beauty of the swirling grain and colours of this Rosewood we are using for all the interior cabinetry. These are the first of MANY more panels to come out of the veneer press. The brown tape is used to hold each seam of veneer tightly together when they are being glued up. Each of the hundreds of pieces in this eXtremely large jig saw puzzle of cabinetry requires its own combination of veneer, solid rosewood and solid beech such as you can see in this piece that has just been glued up and is ready to have its edges trimmed and corners rounded prior to being machined for biscuits, dados, rabbets and other joints.
Adding plywood to the mix, here we see all four woods coming together for this corner where a solid beech inner block is faced on two sides with Rosewood veneer, one side with 10mm 3/8” thick solid Rosewood and the fourth side glued to the vertical sheet of marine plywood.
If you are not familiar with the term “biscuit joint” is a very strong and fast way to glue two pieces of wood together with a small oval “biscuit” made of compressed wood that tightly fits into matching grooves cut into the two joining pieces. In our case these joints are mostly used to keep two parts precisely aligned and edges flush as they are glued up and the whole assembly is then held together with other joints and ultimately fastened super solid to the aluminium and wood inner frames of the boat. One of the great joys I learned first hand while sailing our previous all steel sailboat for over 12 years was discovering how QUIET metal boats are. Unlike other hull building materials, steel and aluminium hulls don’t flex and move when at sea so there is not the typical cacophony of squeaking wood joints that is typically prevalent in non metal hulled boats. When you add all the 50mm / 2” thick EPDM foam insulation we have installed you end up with an eXtremely quiet boat. Subtle differences to some perhaps but this lack of such intrusive noises is a huge part of the beauty I feel when at sea in such boats. Here is another example of how some of the wooden jig saw puzzle pieces are joined, this being a half lap joint where two dados or slots are cut half way through each adjoining sheet and then slid together. A bit hard to envision at this point, but Omur our Head Cabinetmaker is putting together the inner framework that supports the king sized bed in the Master. The vertical sheet to the rear is one half of the large headboard which extends up to the ceiling. Lots of details have changed since this rendering but it will help you visualise what you see Omur putting together above. A few more details of the cabinetry craftsmanship is seen in this example of how every exposed edge of plywood has this kind of T insert to give the edge that 10mm thick solid Rosewood …. rather than typically just being veneered over.
This is eXtremely eXpensive in terms of both labour and wood but two big reasons we have gone this route. First is to prevent having any exposed veneer edges which over years of use would end up coming away and splintering.
Second being that I am insistent of not having ANY sharp 90 degree corners on our boat! They must ALL be rounded over as you can see in this quick sample board we made up. The vertical corner has about 20mm radius and the outer edges you can see on top here are about 5mm radius. Needless attention to detail some might say but for me, the feel of smooth rounded wood edges is part of the “emotional design” I am striving for and is a very significant factor in the Safe-Comfortable-Efficient trifecta of primary characteristics these XPM boats.
Carrying my insistence, obsession if you insist, with having rounded edges, I’ve come up with what I’m calling a “quilted” look where two edges join each other, even if they are glued such as this one. Another bit of attention to detail if you look REALLY closely (click to enlarge) is how the Rosewood veneer has been applied AFTER the solid Rosewood T edging has been glued and trimmed flush with the underlying plywood. The MUCH easier way to apply solid wood edging to veneered plywood can be seen in this illustration where you first apply the veneer to the plywood, trim it to size and then glue on the solid wood edging last, then trim and sand the two flush.
Works well enough but you tend to see the glue line and even the smallest gap or splintering between the veneer and the solid wood edging. If you look back at the photo of the “quilted” joint above you will see that by overlapping the veneer on top of the solid wood edging and then shaping the rounded corner, the grain of the veneer flows smoothly into that of the solid wood edging.
Again a MUCH more labour intensive detail but Naval’s cabinetmakers and I wouldn’t have it any other way and when you see the results once the final finish has been applied I think you too will agree it was all worth it. Continuing with corner details you saw the prelude to this last week as the solid Rosewood was being glued to the Beech block underneath and now this has been machined with a 50mm / 2” radius. Ends capped with Rosewood veneer as a small part of this will be seen as you will see as this bed frame is assembled, the 50mm corner will fit into these two hollow cored sides to the dropped ceiling box above the bed, as per the rendering above. Just dry fit here but it shows how the two 50mm corner pieces fit with the three sides of this frame. All those adjoining edges will be rounded over to create that “quilted” look before they are glued up with biscuits.
A few more details on weight saving for those still bearing with me, those three flat sides above may look like they are made of a single plank of solid Rosewood but they are in fact mostly hollow box frame sections that are very light and very stable. We deposit more weight saving dividends into our weight budget by using poplar cored marine plywood for all the cabinetry rather than Baltic birch marine plywood as it is considerably lighter, more dimensionally stable and has a flatter surface for veering.
Saving the best for last in this focus on cabinetry corners, here is a peek at how Omur and his crew are creating all solid wood large 100mm / 4” radius corners for all the vertical edges throughout the interior.
Veneer would have been SO much easier and cheaper but as you know from your home, these corners are high traffic areas that suffer a lot of wear and tear over the years and if these were done with veneer they would show this very visibly and with no real way to repair. Instead all corners and edges on Möbius are solid wood which will stand up to this wear and tear indefinitely and will be relatively easy to repair any damage back to like new for the very long life these XPM boats will surely have.
As you can make out here, three lengths of solid Rosewood have been cut with edged mitered at 30 degrees and biscuit glued together to form a 90 degree corner. Gluing the three boards has to be done in two steps as trying to clamp all 3 at the same time would not create perfect glue lines and then once all the glue is cured the outer surface is machined to the 100mm radius followed by copious amounts of elbow grease with a radiused sanding board.
Knowing what went into creating this corner will help you understand Omur’s hard earned look of exhausted pride as he holds up this first prototype of such corner construction that he and his team will now use for all the many other corners onboard XPM78-01 aka Möbius.
I may not be as exhausted but I am certainly just as proud and happy as Omur and his talented team of cabinetmakers are. And they are just getting warmed up so stay tuned for much more from all the talented people on Team Möbius as we continue to bring you these weekly progress updates.
Short but hopefully sweet video here is your video summary for this week. Will try to do more next week.
As always, thanks for following. Like, subscribe and most importantly add your comments, suggestions and questions in the “Join the Discussion” box below.
NOTE: I’m having trouble splitting this week’s update post into two so it will have to stay here as one big posting. So go get a comfy seat and a good beverage and I think you’ll enjoy this longer than usual posting. As you’ll see it has be a VERY busy and eventful week!
OK, back to our regular programming now………………………………
It was one of the longest and closest beauty pageants in history but the jury is finally in and the 2019 Miss Möbius World Wood has been crowned.
You saw some of the run up in last week’s post such as this photo of the final four veneer contestants in the Au Naturelle portion of the contest. And here are the four finalists, resplendent in the early morning Antalya sun sporting their solid Rosewood edging with their carefully applied coats of clear varnish buffed to a lovely matte lustre.
The two Siamese twins in the middle are Anzem commonly known as African Bengi and the two contestants on either side as well as the other set of twins angling for attention in the background, are all different cuts and types from the Pelesenk/Rosewood family which is often mistaken for Lignum Vitae. According to their application form and family tree (sorry) these three are all
“Tropical hardwoods known for their beautiful figuring and rich, dark red or purplish color streaked and variegated with black. A very hard, heavy and highly valued cabinet wood sustainably obtained from several tropical leguminous trees of the genera Dalbergia and Machærium Takes a high polish easily and used for expensive furniture and jewellery making. The Rosewood name is derived from aroma wood exudes as it is sawed.
By whatever name, and with apologies to William Shakespeare I think you might agree that these woods are a great example of how “A rose by any other name would smell as sweet.“ and look as beautiful as vividly on display in these photos.
So, without any further ado (not to be mistaken for adieu!), the winner of the Miss Möbius World Wood contest is ………………………………….
This beauty, known by her parents (aka lumberyard) as “Kisa” according to the label on the sample strip of veneer our awemazing interior designer Unzile had sent to us last week. Kisa is seen here rightfully showing off her beautifully random swirling streaks of a colours ranging from light brown through burgundy wine to black.
In this pose you can see her solid wood edging and radiused corner. This type of solid wood radiused corner will be used throughout the interior with varying radii from 25mm to 50mm depending on their use on cabinet edges, wall corners, etc..
We can’t wait to see how this will look in larger forms as the Xtremely talented Naval cabinetmakers start building the interior walls and cabinets so you will soon be seeing LOTS more of Kisa in the weeks and months to come.
Speaking of Beauties, I snapped this quick pic of my Beautiful Bride, aka Captain Christine, taking on the next daunting task of choosing all our other interior materials. We wanted to start with finding our Goldilocks “just right” wood first as Mother Nature has such a range of colours and we weren’t sure just which ones were going to call our name the loudest.
With Kisa being the winner we now know the colour pallet she brings aboard and so Christine is now moving on to the selection of materials and colours for the floor, ceiling and walls.
As many of you who have built or remodeled homes, floating or otherwise, know all too well, there is a mind boggling number and range of colours, textures and materials to chose from so this is a tall mountain to climb but a thoroughly fun part of our adventure.
With our wood now known the next material and colour for the interior decision hierarchy is the floors and we are fortunate enough to find ADO Floors right here in the Antalya Free Zone and almost beside Naval Yachts where we are building Möbius. The ADO Group is a 62 year old company now making some incredible “Luxury Vinyl” flooring which has proven to be a just right fit our priorities of Xtreme safety, comfort, durability and low maintenance. The flooring we are going to use is part of ADO’s “LAAG” series which is found not only in homes but also industrial buildings such as airports and shopping centers as it is simultaneously tough, non-flammable, anti-bacterial as well as being sound insulating and waterproof. Importantly for us this vinyl plank flooring also works well with our in floor hydronic heating so having checked all our “must have” boxes we have another winner this week!
Difficult to capture in a photo and with must one small piece, but the sample above is the one, “Aperta 2010” is calling our names the loudest and what we’re going with. In addition to its other great properties we also went with this because it has a significant 3D texture that I would best describe as being similar to the texture of the raised grain of aged wood siding on old buildings. Not sure how well that captures it but this texture provides the critical “grippiness” and non slip that we need on our floors when we can sometimes be walking about in bare, sometimes wet feet on a boat that is Rockin’ & Rollin’ in heavy seas or boisterous anchorages.
Cabinetry Wood: CHECK
Interior Flooring: CHECK
Walls, Upholstery, Ceilings? TBD
Before we leave this interior topic, some of you may be interested in knowing the overall concept and theme we have for our interior spaces. As you’ve seen and read the exterior will be all business, function first, raw unpainted aluminium, no paint, no wood no stainless and with a style and look that is “lean and mean”. More industrial bordering on military so as to present a “don’t mess with me” vibe to any onlookers with less than friendly and honourable intentions. On the outside we want to blend in an fit much more in a fishing port rather than a superyacht marina.
But on the inside we want to be transported to the opposite end of this spectrum to be bathed in natural light and fresh air and immersed in a world of carefully crafted cabinetry using woods and materials which radiate a feeling of warmth and beauty. Materials on the walls, upholstery and ceilings which provide the perfect backdrop for the artwork of friends, family and some rare special mementos we have picked up in our decades of travel around the world.
Having lived aboard our previous sailboats for decades, we are inextricably connected to Mother Nature and the environment we are anchored in which is usually an isolated “only boat in the bay” type anchorage in the latest Xtremely remote location we serendipitously find ourselves in and so we want to bring that with us and not be cut off from it when we step inside. Hence the 360 degrees of glass surrounding our entire Pilot House/SuperSalon which is our primary living space and all the huge hatches we’ve designed which you’ve been seeing installed in the past few weeks and will see a bit more of below.
I will tell more of the story behind our choosing Möbius as the name for our Goldilocks boat but for now I’ll encourage you to Xplore and play with these intriguing wonders of math, space and surfaces which have captured my imagination since I was a very young boy. You can start with this brief Möbius strip explanation or this 3D “Klein” vessel exploration where the little GIF animation to the left comes from.
One of the many fascinating features of a Möbius strip or Klein bottle which so boggled my little boy mind, which is still VERY active, is that they have no inside or outside, no boundaries, only one continuous surface and one continuous edge. Or as Ross Dawson captures it so well in this little graphic on the left; “The inside is the outside”.
If you are still with me after my all too typically “brief” lead ins, my point is that we are also going to adopt a Möbius theme to help us design our interior such that our “inside is the outside”. At the very top of our interior design triangle the theme we have come up to help create “the inside I the outside” is to replicate a similar orientation and colouration of the natural outside world. The floors will give us a feeling of the ground that is under our feet on remote beaches, walks on old docks and you can now see part of what led us to chose the vinyl floor sample above. Our lower vertical surfaces will be reminiscent of the trees, jungle and forests we see and wander through ashore with our use of the beautiful Miss Kisa Rosewood for all the cabinetry and lower wall surfaces. Then we are going to have a horizontal band at about countertop height which endlessly wraps itself around the whole interior to create an internal version of the aqua marine horizon we are accustomed to seeing all around us. Above the horizon there will either be views of the natural exterior vistas that surround us or lighter coloured leather and fabric covering the walls and higher cabinetry and makes the transition into the whites of the clouds above on the ceilings.
In short, floors that mimic sand and rough wood surfaces under our feet and a horizon below which are forests of beautiful wood and above which are open expanses of sky and clouds. Lucky for you and your eyes, I’ll leave it at that for now and return in future posts to give you more of the story behind the naming of our boat and the design of our interior.
The other bit of progress on our interior is these two sheets of a larger shipment which arrived this week. Can you guess what this is for?
This close up view (click to enlarge any photo) will help answer that. This is the first in the multi layered insulation of the interior bulkheads to keep them Xtremely well insulated both thermally and acoustically. As you can see here, this first layer already has 3 layers of its own with an inner 3mm layer of highly compressed EPDM sandwiched between the 17mm layer of white foam and the 6mm layer of black foam. The outer side of the black foam is covered with “peel & stick” industrial adhesive which will be used to attach the foam to the flat aluminium plate of the bulkhead “walls”.
Given the Xtreme nature of how these XPM boats will be used these additional aluminium fasteners are glued to the aluminium bulkheads prior to the foam sheets being pressed in place. Once the foam is in place one way lock washers are pressed overtop of the protruding portion of these aluminium “nails” to lock them in place. The walls will then be covered with a further layer of special acoustic plywood which is also constructed of multiple layers of wood and fibre and I’ll show you that in a future post.
In case you are wondering, this Xtra special acoustic and thermal insulation on this side of these WT bulkheads is over and above the already eXcessive 50mm/2” EPDM foam that is on the other side, Why go to such Xtra work and expense? This treatment is being used here to ensure that none of the noise and heat from the engine room is able to sneak into Christine’s Office/Guest Cabin. The WT bulkhead between our Master Cabin and the Forepeak will receive similar treatment to insulate it from the sounds of the anchor chain, windlass, etc..
Speaking of insulation, good old “Mummy” continues the seemingly endless task of applying the nautical miles of EPDM foam insulation that covers every internal aluminium surface and if you look closely here you’ll see him carrying yet another roll of EPDM up the steps to the Swim Platform on Möbius.
In addition to installing all the EPDM insulation Mummy has also been in charge of another long and tedious task; applying all that beautiful shiny aluminium foil cloth overtop the EPDM in places like the Basement as you see him doing here. Here is more of Mummy’s handiwork installing the EPDM insulation inside the “doghouse” where you step into the Workshop from the Swim Platform and you can also see that the overhead hatch is now all welded in place patiently awaiting Mummy to find the time to put in the EPDM around it. More EPDM seen here in our Master Cabin where Hilmi the electrician continues his work installing all the perforated AL wire trays that he will soon start filling up with many nautical miles of wire and cable.
At the other end of the beauty spectrum, some might say the more masculine end, you may also recall this depiction of the Fuel Supply and Return manifolds from last week’s progress update and we’ve now got an update on that as well. Here is the first phase of building the first of what will be many different manifolds for fuel and water. As per the drawing above this is machined from a single length of 70mm / 2.75” square solid aluminium that is bored out down its centerline to provide the common internal reservoir which feeds each of the six 316 SS full flow ball valves on the top and bottom, one for each integral fuel tank that forms the hull compartments below the tank tops you see here.
The same 3/4” ball valve on the right end of the manifold is where the main supply/return line lines connect and bring fuel to/from the Day Tank in the Workshop. All the rubber 20mm ID fuel hoses will connect to the ball valves using the blue/red JIC AN-12 fittings you see two of here. These components are as expensive as they look although building in house helps but we gladly spend our budget on mission critical systems on our boats and on a power boat the fuel system is definately mission critical.
If this were a water manifold, the supply/return valve and line would need to be larger to have enough flow for multiple lines being used simultaneously, but in these fuel return/supply manifolds allow us to select which of the six fuel tanks we are taking fuel from and which one we are returning to so there is never a situation where more than one tank is being used at the same time.
Many may feel that Kisa and her wooden sisters above are far more beautiful but as I like to remind people, beauty is a FEELING using any number of our senses not merely what we see so these Xtremely robust fuel manifolds are Xtremely beautiful to me and make us feel Xtremely warm and fuzzy knowing that they will never leak, are easy to use and ensure that our fuel is safely transported to all diesel consumers and tanks.
More fuel related progress, the Fuel Vent boxes are now all welded in place sporting their requisite hose barb outlets for the 50mm vent hoses to come. More hose barb pipes and some elbows all machined ready for welding into the tank tops for the other end of the hoses running from the Fuel Vent and Fill boxes into the fuel tanks underneath the Basement. Like this. Final Fuel related update for this week, these two threaded flanges are now all finished, insulated and foiled awaiting the JIC AN-12 fittings to be installed for the fuel hoses on either side of this WT Bulkhead in the Basement. Switching from Fuel to Water for a bit, another exciting milestone this week was the start of installing the Sea Chests into the hull. I’m a huge fan of using Sea Chests for bringing sea water into the boat for things like the supply for the watermaker, salt water wash down pumps and the wet exhaust on the Gardner. Rather than having individual sea cocks perforating the hull in every location these sea water consumers, a single large diameter Sea Chest pipe can be used to bring the sea water inside and act as a manifold for any number of outlets via a SS ball valve for each one.
HOWEVER, my top priority is keeping the sea OUT of our boat so cutting big holes into the hull BELOW the Waterline has my full attention and we go to great lengths to ensure that we keep the sea on the outside of the hull! Hence these special order Xtra thick aluminium pipes from which we will fabricate our Sea Chests. The one above is for the Intake Sea Chest in the Engine Room which is 120mm / 4.7” ID and the walls are 15mm / 5/8” thick. The pipe on the left here will be used for one of the lower volume Sea Chests and is 90mm / 3.5” ID. In addition to the Sea Chests for bringing salt water into the boat we will also have Sea Chests for taking Gray and Black water out. Both the Intake and Exit Sea Chests extend up well above the Waterline, about 30cm / 1’ so I can service them while the boat is in the water and each have a thick flange on top for a clear Lexan cover. Having a clear cover allows me to quickly inspect what’s going on inside and if needed I can either remove a small threaded plug in these covers large enough to allow me to stick a wood dowel “broom handle” or the like and push out anything that might be sucked up, or swims up and blocks the pipe.
Ask me how I know?!!
Here is the Intake Sea Chest being fitted in the forward Starboard corner of the Engine Room.
Once it is welded VERY securely into the 15mm thick bottom plate of the hull it will be fitted wtih offtake pipes leading into large dual water strainers which in turn feed into a manifold with take offs for the wet exhaust system, watermaker and aft deck wash pump. OK, we’ve seen the progress on wood, fuel and water so let’s finish up with fresh Air and Light. Uğur, Nihat and Sezgin continue with their work installing the ten big hatches which will bring in all the fresh air and natural light below decks while we are at anchor. Dorade boxes will look after the fresh air when we are underway and the hatches are closed but we spend the vast majority of our time over the course of a year at anchor so the hatches are critical importance.
The two large rectangular boxes you see flanking the large opening above the Engine Room will provide the air in and out of the Engine Room and Workshop as well as being used for our Outdoor Galley with BBQ, sink, counters, etc..
We are out on the forward area of the Aft Deck behind the Pilot House where there are stairs down into the SuperSalon or up to the SkyBridge. This is all overtop of the Guest Cabin and Christine’s Office and the hatch you see Uğur welding above is overtop the Guest Cabin shower.
The 450mm / 18” square one on the bottom of the photo on the left is overtop of Christine’s Office desk and the large 700mm / 28” one under the spiral SkyBridge stairs is overtop the Guest Cabin Queen bed.
Below all this action, the ever present Mehmet is prepping the big 10mm / 3/8” thick frames that go around the perimeter of the Engine Room enclosure and provide the sealing surfaces for the large hinged door that keeps the large opening into the Engine Room you can see two photos above, all watertight. With all that action happening on the Aft Deck and around that Engine Room hatch, the big hatch door has been moved up to the bow and is being cleaned up and prepped for its finish welding hinges and “dog” which are used to latch it tightly shut. Meanwhile, down on the shop floor below the slightly smaller Forepeak hatch door up on the Anchor Deck at the Bow is being fabricated. and seen here upside down ready for the stiffening grid and gasket flanges to be welded in place. Here’s the flip side of that Forepeak hatch which is what you’ll see when up on the Bow. I’ll finish up this very loooooooong weekly update post with this random shot of some of our fuel and water tank access port covers seemingly forlornly awaiting their turn to go aboard and be installed. But wait! There’s MORE!!!
Last night Christine and I had the huge privilege to attend the wedding celebration of one of our Team Möbius members Burak and his fabulous wife Melek. This is a few others other Naval Yachts people, all working with us as part of Team Möbius and joining in on this joyous night celebrating love, life and happiness. Congratulations Melek and Burak! Seeing you so happy makes us happy!!
