It is GREAT to be back together with Christine after our various trips to see family & friends in the US and Canada as well as each of us looking after some professional things with two author conferences for Christine in Florida and a keynote for me in Sao Paulo Brazil. Thanks to Dincer we were able to spend several hours on Saturday walking all through Möbius catching up with all the progress that our fabulous Team Mobius had made while we were gone and you saw all that in last week’s post. This week work continued up on top as window frames went into the Pilot House and the two “wings” that extend aft from it to the Aft Deck were welded up. Meanwhile down on the bottom the last of the hull plating started to go in place sheathing the framing for the keel and prop shaft skeg. Lots to show you so let’s start up top.
This quick render looking from the aft Starboard corner of the Aft Deck will help you see how this area will look when finished. Note how we have extended the thick glass of the side windows aft to create those two wings which along with the cantilevered roof creates a very well protected space when going in and out of the door over on the far left Port corner that leads down the stairs into the Super Salon and similarly protects you when going up the circular stairs on the Starboard corner taking you to the SkyBridge. The two large red boxes house the Engine Room vents which have been designed such that even in a full roll over there would be no down flooding of sea water. We have also shaped these to provide spots for the BBQ, deep sink and countertop as well as storage for wash down hoses.
Here is what the real thing looks like which gives you a good sense of how the Port wing protects that WT door into the SuperSalon.
These two aluminium wing boxes will be home to some additional ducting and fans providing lots of fresh air down into the Guest Cabin and Christine’s Office as well as waterproof spots for the wiring that goes up through the arch tubes for all the antennae, Radar, GPS and many other components that will be mounted on the top of the arch.
Looking at the window frames from the outside you can see how they get welded to the 10mm thick mullion bars to create these eXtremely stiff and strong H shape beams. Note too the wide surface area where the glass will be adhered to similar to the way many of the glass high rise buildings are constructed. This type of construction provides the assurance that these windows can easily handle gale force conditions and safely deal with direct hits from possible large side waves. These glass window areas are engineered to significantly exceed the strength and impact resistance of these areas if they were covered wtih aluminium plate.
While all this was happening up on top of the decks work began on this aft area on the bottom of the hull. A very critical and busy area of the hull with the rudder and the skeg that extends down from the prop tunnel. The Skeg is eXtremely strong as it is the lowest part of the boat and would be most likely to take the brunt of bottoming or striking something. You can see how it is shaped in section to be a carefully engineered foil shape to provide very clear water into the prop and also protect the prop, prop shaft and rudder.
All this is 25mm plate which is capped off with the 50mm / 2” thick shoe plate that tapers to a point just ahead of where the prop blades will be.
This shoe is what the boat will rest on when we are hauled out from time to time and also provides critical protection to the prop from anything we happen to run over such as logs or ice or lines in the water and will also be the first point of contact when, never if, we hit rocks or coral or bottom out.
Something very closely related to all the work you’ve just seen above.
Something we have been working on with a team in Norway for over a year now.
The big deal for us going with a Controllable Pitch Propeller system is that it allow us to dial the just right pitch for any speed and any sea conditions. This in turn lets us have the just right load on Mr. G, our Gardner 6LXB engine which keeps him VERY happy and very efficient. A CPP also gives us eXcellent control when maneuvering in close spaces, fuel docks, etc. as there is no shifting from forward to reverse, just feathering back and forth and being able to hold the boat in a fixed position in varying conditions. We’ll explain and show you more when we get to installing this in Möbius.
The other exciting progress is on the new shipyard being built for Naval Yachts a few blocks over from where we are now. If all goes as planned we should be moving in next month! Very exciting for all of us here.
Those are all full height sliding doors you are looking at here and if you look closely down the right side of the building you can see the office building section at the other end.
Dincer kindly took me on a tour of the buildings and this is now looking at the inside of those sliding. The bay you see here is the “small one” though only relative to the double wide bay to the left here which is where Möbius will soon be taking up residence.
Here is a look from the 2nd floor of the office building looking at that double bay and the yellow crane truck and people will give you a sense of scale for this fabulous new facility Naval Yachts will soon be occupying.
Möbius’ new home will be up against that white wall you see here with lots of space for another ship that will be on the right side of this bay with plenty of room between, in front and behind for machines and materials.
A deservedly proud Dincer showing me some of the the 2nd floor office spaces with large windows into the yard area. Gives you another sense of scale as the shop floor space you are seeing through the window here!
This is where all the work on fitting out and finishing Möbius will take place over the next 14 months or so.
Congratulations Dincer, Baris and everyone at Naval Yachts for this awemazing progress on your new facilities and on Möbius.
I have not had time to put together another video walkthrough for this past week but will work on doing it this week and have it for the next update. In the meantime, here is a short video collage of the work of the past week.
Thanks again for joining us and as always please be sure to add your questions and suggestions in the “Join the Discussion” box below.
Wonderful project. Great team work. Love the design and reading about this powerful monohull.
Is this vessel a family traveling adventure vessel or a light commercial vessel. Seems like the perfect size to pack eco tourist around or film crews doing near shore surveys. Lots of room for sea kayaks and bikes to pack around.
Would love to read the design brif.. I really like the shallow draft advantage, and long and long waterline. SHe would be ideal for working in Cook Inlet. We have lots of tide and sandy beaches to dry out oh. We also have a nasty steep chop that trashes many fishing vessel and crews when the wind is against the tide. Are you going to have stabilizers ? I have lots to read about this project. I hope that Dennis can design us a 65 for Alaskan waters.
Great job team, would love to help you guys any way I can. Wonderful insightful project. WOuld love to see some kind of backup electric drive, for slow speed quite photo surveys above and below the water. with rov’s.
Kind Regards,

Hi Carl, welcome aboard the good ship Möbius and glad you’re enjoying the ride so far.
To answer your questions, this first XPM78-1 aka Möbius will be the new boat and full time home for my wife Christine and myself. We are former single handed sailors before meeting up 5 years ago and becoming double handed at sea and at life and along the way decided we wanted to try the new adventures and challenges of voyaging under power rather than sail and so we spent the past 3 years working eXtremely closely with Dennis at Artnautica to design the Goldilocks “just right just for us” boat and Möbius is the result. Since teaming up with Naval Yachts here in the Antalya Free Zone they’ve decided to create a whole new series of boats under the XPM or eXtreme eXpedition Passage Maker boats and there will be three sizes in the XPM series, a 20m/65.6′, a 24m/78′, and a 30m/98.4′ Dennis will be doing the conceptual designs for these XPM boats and then Naval will do the detailed build plans and building in their new shipyard here which we hope to be moving into next month.
These XPM boats would make great research platforms and I won’t be surprised to see that being the focus of some of the next orders. As for us and Möbius you can read a detailed account of our design process in one of the first posts here called “Project Goldilocks: Mission Impossible or Just Right?”.
As you appreciate we worked quite hard on keeping the draft as small as possible as this opens up so many more options for us to get into bays and areas where other boats can’t go and adds a bit of a safety factor in terms of what we can go over without contact.
All the XPM’s are designed for active stabilisers to be installed if desired by the owners. They have all the framing and sealed coffer dams for these so installation will be a relatively quick and easy job. Traditional fin type active stabilisers from the likes of ABTrac and Niad can be installed but we favor stabilisers based on the Magnus effect such as the ones from DMS Holland’s MagnusMaster and Quantum’s MagLift as these fit better with the use case and design parameters of these XPM boats. They are all electric so no hydraulics involved and they rotate out of the way with almost no protrusion from the hull when not in use. Some of these Magnus Effect stabilisers have been installed on commercial ice breakers with a stout pipe roll bar built over them for added protection so they are very robust and stabilize very well. For Christine and myself on Möbius though we will not install any active stabilisers to begin with as we prefer to go with passive paravane stabilisers in keeping with our KISS approach. We are sailors so quite used to rigging and have designed our paravane setup to be very easy to launch and retrieve and we’ll run that for the first year and see how it works.
Given your location and implication of wanting to use your boat in ice you’d be interested to know that we have designed the XPM’s with this in mind as well. In addition to eXtremely thick hull plates and frames which are on close 1m centers, on the XPM78’s such as Möbius the bottom plates for the first 4m from the bow are 15mm thick and then 12mm thick all the way back to the swim platform. Then there is a 25mm thick keel bar that runs the entire length of the hull and up the full height of the bow so should be up for any ice infested waters you might encounter. We designed this in from the beginning as we plan to go on many high latitude trips on Möbius and she will also be eXcessively well insulted with EPDM on all interior hull surfaces to keep out the cold, or the heat in tropical climes. There will also be hot water based air handlers in all living areas as well as heated floors so we should be able to be both very safe and very warm and toasty when our GPS tells us we are in less than 10 degrees of latitude.
Möbius will not have any electric drive but Naval makes a whole line of electric and hybrid boats under their GreeNaval label so they are some of the premiere experts in designing and building boats with various kinds of electric drive which could be adapted to the XPM series for use cases such as what you site “… for slow speed quite photo surveys above and below the water with ROV’s”
Hope that answers your initial questions Carl and be glad to answer any more you have as the build progresses and you move forward with your new boat project. Thanks for joining us here and stay tuned for much more as Team Möbius continues to make great progress on the first XPM.
