Transfer Time:  Wood, Water, Fuel & Air

Transfer Time: Wood, Water, Fuel & Air

We are all back after a wonderful week off for the big Eid-ul-Fitr or Ramazan Bayrami n Turkish which is the “Festival of the Breaking of the Fast” that occurs as soon as the new moon is sighted at the end of the month of fasting.  Well rested, well fed and filled with gratefulness and appreciation for all we have, progress ramped up quickly on the good ship Möbius on lots of different levels and materials.  The title is in reference to the theme of transfer which prevailed this week including transferring the completed Master Bed cabinetry to the finishing shop, transferring to prepping the Master Cabin to have all its cabinetry mounted, and then lots of work with other transfers such as Dorade Vents for transferring fresh air into the interior spaces and transferring water of all forms (Black, Gray, Potable, Sea) to and from their respective tanks.  Whew!  That’s a LOT of transferring and too many words so let’s jump right into the show and tell for this week of June 10-14, 2019.

IMG_20190613_154102Starting with the transfer of diesel fuel the Day Tank was back in the spotlight as it was completed and prepped for installation onboard.

Nihat on the right here and Uğur provide a good reference to the size of the Day Tank which holds a total of 667 L / 178 USG which is enough for about a day and a half at 10 knots.  We “polish” all the fuel going into the Day Tank using our Alfa Laval centrifuge which I’ll detail in a future post when we get to installing it.  This ensures that all the fuel going into the Day Tank is super clean and that we are assured to have enough fuel for at least a day and a half on passage.

IMG_20190612_142315Following the “belt & suspender” type of redundancy we insist upon for all critical systems, just to be sure the fuel has no dirt or water in it, we have the round drain pipe you see here as the lowest point in the tank to trap and hold any water or debris that may have somehow made its way into the Day Tank.  There will be a 3/4” SS ball valve on the bottom so I can easily pull and test a sample of fuel from here.

Peeking further inside you can see some of the baffle plates which prevent the fuel from “sloshing” from one side to the other as the boat moves.

The fuel goes through another series of multi stage fuel filters as the final steps in guaranteeing that nothing but clean fuel is being fed to Mr. Gee, our single main Gardner 6LXB engine upon which we are so dependent for propulsion.


There is this additional access port in the top just in case I ever need to access the inside of the fully baffled tank when it has lots of fuel in it.  Uğur is tapping the holes in the access port frames for the threaded studs that will hold the gasketed lid tightly in place.
IMG_20190612_142215With all the access ports and baffles all welded up the tank is closed up by welding in this last side.  You may recall seeing this type of slot welding when the hull was being built as this is how you are able to weld a plate where you have no access to the inside.
IMG_20190614_102029With the Day Tank fully prepped, Sezgin our Master Welder then gets the call to finish welding the slots and perimeter of this last side and then …….
IMG_20190613_102416……. lay down the finished continuous welds and fully seal up the drain sump and both access ports.
IMG_20190613_102430Looking down through the top access port down to the one on the bottom, you can see more of the baffles which minimize the weight transfer as the fuel moves about when there is lots of boat motion.

Next week Nihat and Uğur will wrestle this completed Day Tank into the Starboard/Left side wing of the Workshop and fasten it into its full time home up against the WT Bulkhead. 
IMG_20190610_182351Making sure we keep Mr. Gee VERY happy and running well we we also need to feed him cold clean air and that is what Uğur and Nihat are working on here in the Engine Room.  That long rectangular aluminium duct will carry fresh air from the Port/Left Vent Box up above on the Aft Deck down to the floor of the Engine Room.
Aft Deck Vent BoxesOutside looking at the Aft Deck this quick rendering shows how the two Vent Boxes provide additional height and a protected place for the mist eliminating vents that will be on the inside of each Vent Box.

These Vent Boxes will also serve as our outdoor Galley with a BBQ in that aft cut out of the far Vent Box and a sink in the nearest one.
Vent Box ductingThis isolated render of the Vent Boxes in Red and their respective below deck ducting in Purple will hopefully help you see how they direct air into and out of the ER as well as air into the Workshop and the Guest Cabin.

The tall purple duct on the left takes the intake air down to floor level in the ER while the smaller purple ducting on the far side pulls the hotter air out of the ER up and out through the upper demister grill outlined in Green.
IMG_20190611_085546Back to the real world, here is that tall intake duct you saw above as it extends up through the aft deck plates.  The vent box sitting in the top right corner will eventually be fitted overtop of this duct and the air will enter through a demister grill on the inside surface of the Vent Box.
IMG_20190612_103747Back down in the Engine Room looking up at the ceiling on the Starboard/Right upper forward corner we see where the hot ER air exits.  There will be 24V fans to assist with pulling the heated ER air out and creating a slight vacuum in the ER to make sure none of the fumes and heat are pushed out into the Workshop.

The large radius duct all the way forward penetrates the ER enclosure wall and feeds fresh air into the Stbd/Right wing of the Workshop.
Dorade Boxes ForedeckMr. Gee isn’t the only one who needs to be fed lots of clean fresh air, we do too!

When we are on passage and most often can’t have the hatches open we bring fresh air into our Master Cabin with these four Dorade Vents seen here on the Foredeck.

IMG_20190613_103618Dorade Vents are a very tried and true way of bringing fresh air into a ship while also keeping rain and sea water out.  Very simple principle, a tall vent pipe such as the three you see here (forth hiding behind orange welder) set up about 150mm / 6” above the deck and carry fresh air straight down into the cabin.
IMG_20190611_085524I’m determined to have a zero leak boat so I have a zero tolerance policy for any penetrations through the hull.  For example yes of course these vent pipes are welded to the deck top and bottom! 
IMG_20190613_103755These vent pipes are then fully covered by the Dorade Box which Uğur has mocked up a prototype of and is lowering in place here.
IMG_20190613_103746These aluminium Dorade Boxes will be welded to the deck with generous scuppers/slots all along the bottom edge to allow any water that gets in to quickly drain out of the box onto the deck and back overboard.
Image result for dorade boxThen a silicone cowl assembly like this will be mounted on the top aft surface of the Dorade Box to capture the fresh breezes coming over the bow and direct them down into the Dorade Box.  The cowl can be rotated 360 degrees and the mushroom cap you can see in the bottom cutaway section helps deflect rain/sea water out the vent slots around the base and any that makes it down into the Dorade Box below drains out through the scupper slots noted above.
Image result for dorade boxA side section looks like this when you put it all together.  No matter what the weather or sea conditions we get fresh air in and keep water out, just the way we like it!  If we want to really seal these off we just reach up into the vent pipe and turn that little black knob you see in the section above which lowers the mushroom cap and seals it off.  We will also have a bug screen atop the vent pipe to keep those guys out as well.

IMG_20190613_103108When weather and conditions permit though we prefer to have our beautiful big hatches open to let in even more fresh air and lots of light.  So our in house designed and built hatches got some finishing touches as well this week, having their Hinge Boxes all welded up inside where they join the inner deck plate surfaces and tie into the support stringers. 
IMG_20190613_103125Still looking up at this hatch frame we see one more example of how we make sure lots of fresh air gets in while keeping water out with this drain elbow that carries any water that collects in the gutter around the hatch frame out through a hose into an exiting sea chest.
IMG_20190614_102240Continuing with our transfer theme and moving to the Guest Cabin area you can see the black fuel hoses at the bottom of the Starboard/Right side of the hull.  Two of these hoses will carry the diesel from the integral tanks under all the floors to and from the Day Tank which will be mounted on the other side of the WT bulkhead on the far right of this photo.

As you can see the hull walls are starting to fill up with more hoses and electrical cables. 
IMG_20190614_102255Looking a bit like tentacles of some stowaway octopus these hoses are being fed through their respective through holes in the frames and through the welded in penetration collars where they pass through a WT Bulkhead.  Trays similar to the white wire trays you see above will be mounted horizontally to aluminium flat bars that are hiding under the vertical strips of black EPDM insulation you can see on the right but for now they are being routed throughout the length of the sides of the hull.
IMG_20190614_102419Each different type of fluid needs to transferred using a different type of hose specifically made and approved for each purpose.  In this case these clear 19mm / 3/4” ID hoses are for transferring any bilge water which might collect in the gutters running down each side of the hull where the tank top margin plates aka floor, intersect with the side hull plates.  With all integral tanks for fuel and water filling up all the area below the waterline the only place where we have a traditional bilge is below the main engine.
IMG_20190614_102854Moving forward into the Basement area you can see these clear bilge water hoses coming through up near the top of the WT Bulkhead, black fuel hoses on the bottom and the white/blue hose which is for transferring Gray Water from sinks and showers out of the integral tanks below the floors to either an Exit Sea Chest or a shoreside pump-out station.

The black & red pump is one of 18 Johnson SPX Power 16 diaphragm low level bilge pumps which we use to suck up any water that collects in those margin plate gutters along each side.  One of the many benefits of using diaphragm rather than the more common centrifugal bilge pumps is that diaphragm pumps can be located high and dry and they are also able to pull up all but the very last little bit of water.  This is a HUGE improvement and keeps the boat dry and odor free.

IMG_20190614_102528Another example of the specialised pipe and hoses showing up onboard is this white PPR tubing which we’ll be using for the main hot water loop that supplies hot water to all our sinks and showers.  This 25mm / 1” ID pipe will create what will essentially be a large hot water manifold that runs the length of the boat with a very small thermostatically controlled circulation pump which keeps the water at a set temperature.
IMG_20190614_103205Each length of PPR is fully wrapped with this EPDM foam insulation to keep that heat in and increase the efficiency of our overall water heating.  This is the same type of EPDM foam which we have at least 50mm / 2” of covering every interior aluminium surface to create our live in Thermos bottle. 

Our water is heated by a variety of sources, primarily from the Kabola diesel boiler and then supplemented by a heat exchanger off the Gardner main engine when it is running or from electrical coils when the solar panels have already fully charged the house bank batteries.
IMG_20190614_103123There will be T’s coming off this main hot water loop with short runs of equally well insulated 15mm PEX tubing carrying hot water to each individual sink and shower tap.

What all this does is provide near instant hot water to each sink and shower and eliminates the all too common waste of our highly valued fresh water from our watermaker when you turn on the hot water tap and wait and wait for it to get hot.
IMG_20190611_085150Hey!  What happened to our beautiful King bed??
IMG_20190531_144830When we last saw it just before we all left for the holidays it looked like this!

Oh!  More transferring you say?  Right, the bed all comes apart so it can be moved aboard through the available openings, got it!
IMG_20190612_162223Omur and Selim first finished off the base for the mattress with the two removable hatches to provide access to the two large storage areas not filled up with drawers.
IMG_20190612_162234We are loving the contrast between the light coloured Beech being used for these kinds of areas with the dark Rosewood everywhere else.
IMG_20190613_101900One last detail was to route in these slots to provide more ventilation below the mattress and now the whole bed is ready for the next exciting stage; applying the final finish!
IMG_20190612_162343But before we leave the Cabinetmaking shop one more detail I thought you’d enjoy seeing.  This is an example of how to reduce weight onboard.  These are not for Möbius but for another boat Naval is now finishing up and these are the interior doors. 
IMG_20190612_162348Frames are all made from laminations which ensure they are very rigid  and stay flat with no warping.  Extra thickness is provided where hinges and latch hardware will be mounted.  All the cavities have lengths of extremely rigid foam bars glued in place which weigh next to nothing.   Then the door skins are glued on both sides, the whole assembly trimmed to final size and off to the veneer press to have the final layer glued down.  Strong, stable, lightweight and beautiful, who could ask for more?
IMG_20190613_155739Hang on!  Who let Omur and Selim out of the Cabinet shop and into the Master Cabin on Möbius?? 
IMG_20190614_103008Oh right!  This is where wood meets metal.  They are meticulously putting in the wood foundations that all their cabinets will set on and be attached to.  Omur is measuring out the end of the bed unit you’ve seen previously and can see the outline of here. 
IMG_20190614_103040Behind him is this framing around the four access ports into the integral water tanks below all the floors.  These solid wood frames are all sealed with epoxy paint, carefully leveled with the wedges you see here and then glued down to the aluminium tank tops/floor plates with Sikaflex.
IMG_20190614_174702Once all these foundations are laid down all the cavities will be filled with 40mm / 1.6” rigid foamboard and then 10mm marine plywood will be laid down to create the substrate for the final vinyl flooring. 

Before the plywood goes down the foam will have all the grooves routed in place to create the continuous circuits for the 15mm PEX hot water tubing to be pressed into for the hydronic floor heating that will be in all the living spaces on Möbius.

Those with sharp eyes and good memory, I wish!, will note that the walls in the Master Cabin are also filling up.  I’ll cover them in more detail in future posts but the large 50mm / 2” clear tubes are the vents and fills for the water tanks, the smaller 19mm / 3/4” tubing is what you saw earlier for the low level bilge water and the long arced pipe with EPDM black foam insulation running horizontally half way up the wall is the one you saw earlier for the continuously hot water loop/manifold.

But wait!  There’s more!

IMG_20190613_102211Why is Aziz, Director of all Naval’s Interior work, smiling almost as much as me? 
IMG_20190613_102207Because we are both up in the Finishing Workshops looking at THIS!  The first coat of lacquer being applied to all the bed unit pieces. 
IMG_20190614_101541Words can’t begin to capture and articulate my excitement and joy in seeing this whole new stage of the build taking place so I’ll let the pictures do all the talking.
IMG_20190614_101615Here is a bit of a before and after shot with the drawer faces in the foreground being the bare Rosewood and the ones in the background having their first coat on.

IMG_20190614_101715We have decided to use this top quality acrylic lacquer from Sayerlack which is a Sherwin Williams line of finishes for commercial cabinetmaking shops.  Lots of reasons for the choice over the more traditional varnishes but one of the big differences is the ability to have a hand rubbed finish.  I have worked with acrylic lacquers for decades in my prior woodworking and antique car restoration days and it is hard to beat the beauty of a hand rubbed finish.  A HUGE amount of added labour but as I think you will soon agree when you see the final result it is SO well worth it.

IMG_20190614_101338This is just the first coat and BEFORE these other pieces of the Master bed unit have been sanded smooth prior to the next coat so just wait till you see them when they are fully finished and rubbed out.

Whew!  Obviously things quickly got up to speed as we all returned fat and happy after the big Bayrami  holiday week.

With such a wonderfully diverse spectrum of interests all of you reading this have it is a challenge to gauge the just right amount of detail to provide in these posts.  I tried to cover all this progress as quickly as I can but it is still quite long so if you’ve made it this far thanks for persevering.  Hope you enjoy it and please do let me know in the “Join the Discussion” box below what you thought and add any questions or ideas you have to add to the value for all of us here.



Drawer-ing to a Close

Drawer-ing to a Close

Progress for this last week of May 2019 was all about finishing the cabinetry for the King bed unit in our Master Cabin.  The focus was on completing the construction of all twelve drawers that make up the large high base, hence this week’s title, as well as finishing the dropped overhead ceiling of the headboard.  My brother Bruce and wife Lyla flew out early Friday morning and my cousin Donna and husband Jamie flew in a few hours later from Doha in Qatar so there are still no vacant rooms at the Hodgins Bed & Breakfast and we are enjoying getting all this extended time with friends and family as we share this fascinating part of the world and all the wonderful people, culture and food.

Right now though, let’s go to bed OK?

For those who might be new to these weekly progress updates on the building of our new home/boat motor vessel mv Möbius, Welcome, and here are some of the early renderings of what the whole bed unit and Master Cabin will look like when completed.  We’ve made a few changes as you’ll see in the real life construction pictures here but the overall layout remains the same.

02This is what the King bed and drawer unit will look like when you are standing near the front of the Master Cabin looking aft.  The two wardrobe doors on your left will end up being wood and upholstery rather than glass and all six slots at the end of the bed will be drawers but most else stays the same. 

You’ll note some steps to get up to the raised floor on the right/Port side of the bed to make it easy for Christine and Barney to get up and down from there and making the bed easier. 

01Stepping a bit further back and looking down the centerline of the boat you can see part of the Washer & Dryer cupboard doors on the left and the etched glass cornered walls of the shower on the right.
04Moving over to those steps and looking across the end of the bed towards the Starboard hull shows the large bureau of drawers with the 3D Möbius strip sculpture floating in the space above and the other full height wardrobe by the entrance door in the far right corner.
03Standing just inside that entrance door on the other side of the bed looking forward gives you a good look at that glass cornered shower with the adjoining toilet forward and the Vanity sink outside at the very front.
IMG_20190531_144927Jumping back into reality and forward to the end of the week here is what the real Rosewood bed unit looked like.  I will rewind the clock to Monday morning now (May 27) and we can watch the progress of getting to this point.
IMG_20190527_112654I am holding one side of the very slick drawer slide hardware we will be using for all the drawers throughout the boat.  These are the latest version soft close bottom mount drawer slides from Blum hardware, which makes the highest quality drawer slides I know of.  Once the drawers are in place it all becomes invisible and they glide open and close like silk.
IMG_20190527_112706The drawers sit on top of the left rail you can see with the little finger clip you can barely make out at the far end (click to enlarge any photo) and that light grey cylinder on the right is part of the incredibly smart open/close mechanism.  When you go to open the drawers there is a spring loaded resistance for the first 50mm/2’ or so before the magnetic latch releases and the drawer slides smoothly open as far as you like in a two stage extension.  Then a light push and they slide forward till the magnet catches it and slowly closes the rest of the way and holds it tightly closed.  Perfect setup to keep all the doors closed as the boat tilts and rolls at anchor.  We then have additional latches to mechanically lock the drawers closed whenever we are on passage and the boat’s movement an become more pronounced.  They’re expensive but they are SO worth it for the smile they put on our face every time we open or close them.
IMG_20190528_103959Moving on to the construction of the drawers themselves, this is a stack of some of the drawer carcass sides fresh out of the veneer press after their solid Rosewood edging had been glued in place.
IMG_20190528_103540Selim uses this random orbital sander to smooth and flatten the drawer sides while they are easy to get at before being glued together into a complete drawer carcass or box.
IMG_20190528_170212Upper solid edges of the four drawer sides are rounded over and then …..
IMG_20190529_101949…. each matched set of drawer sides are set in their respective drawer slots under the bed ready to be fitted and glued up.
IMG_20190528_170027With dados/grooves and biscuits cut for the corner joints and for the drawer bottoms to slide into, Omur checks that the diagonals are equal as the best way to ensure the drawers are being glued up exactly square while Selim stands ready to clean up any glue squeeze out before it dries.
IMG_20190528_170111Looking at the rounded top edges of the drawer shows how the back side is set a bit lower to allow air to easily move in and out as the drawer is opened and closed.
IMG_20190528_103617With the drawer sides all glued up and drying, attention turns to the individual drawer fronts, seen here with their solid Rosewood edging mitre glued in place.
IMG_20190530_103810Before taking them over to the veneer press Omur carefully fits each drawer front so they all have the same 3mm space around them using 3mm thick shims, two of which you can see sitting atop the bottom drawer here.

Glued up drawer boxes wait patiently on the left to receive their drawer bottoms and then have the front faces attached.
IMG_20190530_103826Using 3mm spacers he trims each drawer front to final size.  Our eyes are very good at noticing the slightest variation in such thin slots such as between each drawer front so this requires great care and attention to get them perfectly parallel and evenly spaced.
IMG_20190531_144907Once each drawer front has been trimmed to final size they head off to the veneer press to have both front and back covered in matching Rosewood and once dry every corner edge is rounded over with an 8mm radius and they are ready for their final fitting.
IMG_20190531_144911The drawer faces are taped in place so they don’t fall out as this is all part of the dry fitting before all these parts are finish sanded and ready to head off to the finishing shop where they will be varnished and buffed to a beautiful matte finish and then assembled onboard.
IMG_20190531_144901If you spotted this black strip in the photo above and wondered what it was for, this is a sample of the thin coloured strip that will form the “Horizon Line” I’ve described in previous posts which will flow horizontally throughout all the cabins in the boat.  This is just a sample for fitting purposes and the final strips will be a random swirling pattern of aqua marine blues and greens to simulate the water and waves which make up the horizon line that usually surrounds us around all 360 degrees of view when we are anchored in the remote locations we most often favor.
IMG_20190527_112738Lest the drawers get all the attention this week, Omur and Selim also spent time finishing the dropped ceiling that sits directly overtop the head of the bed.  We have dropped it down a bit further than in the renderings above but same basic layout. 
IMG_20190528_170243With the 15mm / 5/8” plywood bottom of the dropped ceiling box glued in place the Rosewood edges are all radiused and prepped……
IMG_20190529_125822 …… the ends are have their locator dowel pins installed and biscuit slots cut ready to be fitted into the headboard and vertical side posts…….
IMG_20190529_183033….. and temporary braces are clamped in place to do the final fitting of the dropped ceiling to headboard joints.
IMG_20190531_144822All this attention to detail will seem over the top to some perhaps but not to us when our eyes behold results like this! 

As your eyes naturally follow the grain patterns in each piece note how they have all been carefully chosen and aligned both vertically and horizontally to be a continuous matching flow of the original grain of the individual tree these were cut from.
IMG_20190530_183022We had a new four legged visitor at Naval Yachts this past week when Hakan our CAD Cabinetry detailer brought his super cute puppy “Sheila” to work with him.  This photo will also allow me to introduce one of the newest members to join Naval and Team Möbius.
Please meet Yesim who is our lead Interior Designer and master of 3DMax software which she uses to turn Christine and my visions into fully rendered masterpieces which Hakan can then use to create all the detailed joinery which in turn goes over to Omur and all the others in the Cabinetry shop for them to build things like the bed unit we’ve been featuring this week.
IMG_20190531_144952Speaking of Omur and Selim, no rest for them as they quickly moved from working on the bed to starting to create the panels for all the other cabinetry in the Master Cabin which you see in the renderings at the beginning of this post.

Hot off the veneer press they peel the veneering tape that holds each adjoining edge of veneer in place while it is being glued to the plywood panel.
IMG_20190531_144917Here are the first sets of veneered panels stacked up against the bed unit ready to be trimmed and cut to shape for things like the wardrobes and other cabinetry in the Master Cabin.

Those candle flame like parts of these panels are the matching portions of the natural grain at the transition between heartwood and sapwood of the Rosewood tree.

You will be seeing much more of this as we watch all this other cabinetry take shape.

IMG_20190527_162250Not likely too exciting to most of you but sure is to us as more and more materials and equipment start to arrive for the many systems that are about to be installed in Möbius. 

This pile is a small portion of the hoses that will be used to plumb the fresh and potable water systems.  The coils of blue and red hose are PEX 15mm tubing that will be used for all the hot and cold water runs to sinks, showers, toilets and bidets and also used for all the hydronic heated floor circuits that run through all the floors in each of the three cabins to keep us toasty warm and comfy in all the high latitude locations we want to explore.

IMG_20190527_162430Here is another pile of recent arrivals, this being some of the many diaphragm bilge pumps, domestic water pumps, ball valves, strainers, etc.
IMG_20190528_103753I will close out this week’s progress update with this shot of the Port side of the Master Cabin bed unit which really shows off the full spectrum of grain and colours in the beautiful Rosewood you will soon see throughout the interior of Möbius.  Go ahead, click to enlarge, you know you want to!

Eye of the beholder always applies of course and this makes my and Christine’s eyes sparkle with excited anticipation of being surrounded by this natural beauty every day we will be living aboard our newest floating home and magic carpet ride around the world.

This coming first week of June is a big national holiday following the end of this year’s Ramadan.  The month of daily fasting ends on Monday and Eid al-Fitr 2019 officially begins on Tuesday, June 4th so all of us on Team Möbius are all going to take advantage of this opportunity to get a few days of much needed R&R this week.  I may put together a post here if I have time as there are several topics I’m meaning to discuss and share and then I’ll get back to the next weekly progress update in about two weeks.

We hope you too are enjoying the start of summer here in the Northern hemisphere and that our southern hemisphere friends and family are staying warm and enjoying the change into winter down there as well.
