The Jig is UP!

The Jig is UP!

This post covers the fist two weeks, April 2 – 13, 2018  with an overview of the very beginning of building the hull for our new 24m expedition Passagemaker named Möbius.  Before we can build the hull we need to build the jig that holds the hull as it is being built and that’s what I’ll do my best to summarise below.

**  For those of you who prefer or have less time I have compiled a video of these past two weeks and put it at the end of this post., so you can scroll down to the bottom to see those now if you’d prefer.  Please be forewarned though that I’m new to video and not had much time for editing so far so they are pretty rough but hopefully add to the text and pictures here to give you a better sense of this project.  I’ll work on my videography skills as time goes on and thanks for bearing with me.

PGL sketch 67This is what Möbius would look like naked.  That is if you stripped off all her outer skin by removing all her hull plates.  Easy enough to do in the 3D CAD model as shown here by simply turning off some layers and this lets us see her lovely “bones” in the form of all those transverse aluminium frames and the interlocking longitudinal stringers which provide the just right combination of maximum strength and rigidity and minimised weight.

With all the AL hull plates welded in place, which vary in thickness from 6mm at deck level and increase through 10, 12, 15 and 25mm as you move down towards the center keel the hull becomes about as bullet proof as possible.  Much more about the hull plating in future posts as the purpose of this post is to talk about the jig which is the first thing being built because it is the jig which will hold all those frames in just the right position as this skeleton of interlocking frames and stringers is assembled and the hull plates are welded on.

PGL sketch 67 - invertedGiven that the hull will initially be built upside down it will look more like this and it may help to keep this image in mind as you read through the rest of this post and see the jig being assembled in the coming days.  Note however that the Pilot House structure which sits up on top of the deck will be built separately off to one side and then lifted up onto the completed hull after it has been flipped right side up.

The purpose of this jig is to provide an accurate base upon which to erect and assemble the hundreds of CNC cut aluminium ** parts as they are assembled pretty much like a “big boys” Erector or Meccano set if you’re old enough to have such fond memories of building things with those kits like I do. Or you can think of it like those large 3D jig saw puzzles of things like dinosaurs and such.

** Yes, this is the right way to spell aluminium but I’ll often just refer to it’s elemental symbol of AL as aluminium is element 13 on the periodic table. It seems that Sir Humphry made a bit of a mess of naming this new element, at first spelling it aluminium (this was in 1807) then changing it to aluminum, and finally settling on aluminium in 1812.

Hull structure details AnnotatedThe internal framework consists of transverse FRAMES spaced about 1 meter apart and then longitudinal STRINGERS which fit into interlocking slots cut into the frames to tie it all together.

Different builders and welders have different preferences for building hulls and as is most common practice the experts on Team Möbius prefer to start building the hull upside down.  Reasons for this upside down beginning are many and include making it easier to accurately position all the vertical frames in just the right spot along the 25mm center keel bar which starts way up at deck level of the bow and continues all the way down and back to the very aft end of the hull at the swim step.  With these frames erected and locked in place on the jig, the longitudinal stringers which in most cases run the entire length of the hull, will slide into slots along the edges of the frames. 

PGL sketch 68As each interlocking stringer is slid in place the whole skeletal framework aligns itself more and more precisely due to the self correcting nature of this technique.  Yet another benefit of accuracy and time savings achieved by building the virtual boat in 3D CAD and then feeding this data to the CNC plasma cutter.  Once this underlying framework has been assembled and mostly just tack welded together it will be double checked with laser sighting levels, transits and lots of measuring to ensure it is completely true to the 3D model. 

Being upside down it will be easier to position the precut and shaped hull plates and weld their outer seams.  At this stage the jig will have served its purpose and be disassembled so that the hull can be moved out of the building and using a pair of large cranes the hull will be very carefully and slowly “flipped” right way up and moved back into the bay.  While all this hull building has been going on the Pilot House structure will have been built in a bay off to the side and ready to be positioned on top of the deck and the complete hull can now be welded up.  Finishing all the welding or “hot works” marks the end of Stage 1 of our 4 stage process to build the fully finished boat.  We estimate this Stage 1 will take about 5 months so the current rough estimate is that we hope to have all the “hot works” done by the end of September and be ready for Stage 2 which is the fitting of the engine, CPP propulsion and most of the systems onboard for HVAC, water, electrical, etc.

But let’s get back to the current task at hand; building the jig for building the hull.

Hull jig frameworkTo help you make sense of what you see in the videos and photos here are some photos of the drawings the guys are using to build the jig.   This first one shows an isometric view of all the AL components of the completed jig.

Hull jig frame spacingThis is a plan/top view of the hull building jig and if you click to enlarge this you can see all the dimensions they use to bolt all the vertical supports to the concrete floor.

There are a total of 22 frames spaced one meter apart and sequentially numbered with Frame #1 located aft of the bow and frame #22 at about the end of the aft deck.  Add in the meter in front of Frame #1 for the bow and almost 2 meters aft of #22 for the last bit of the Workshop and then the outer swim step and boarding area and you have a 24 meter boat.

Hull jig support profileKeeping in mind the hull will be built upside down on this jig, and depending on your spatial thinking abilities, this profile view of the jig might help you make sense of what you’ll see in the videos and photos.  The top of the jig surface is at about deck level and as you move from left to right on this profile/side view, you first see the aft deck which will be overtop of the Workshop, the Engine room and then Christine’s office/Guest Cabin.  Next comes the spot on deck where you will step down to the floor level as you enter the Pilot House or what we are calling the SuperSalon.  Being upside down this means the jig needs to go up and then where the Super Salon ends the forward deck begins and extends to the bow on the far right of this drawing.  The first 4 meters or so of the bow are sloped down as you move forward toward the bow as this is the anchor deck overtop of the forepeak storage area and we want all the muck and water from washing down the anchor as it is raised to easily run off the deck at the bow.

IMG_20180326_123351This is the bay, approximately 30 meters long overall where the hull for Möbius will be built but as you can see the first order of business was to clear and clean it out and there was one rather large item to remove in particular.  This is the GreeNaval 47 or GN47 electric hybrid which has been been fully powered up and already run through some initial sea trials (video here).  Now she is waiting find her new owners so they can make the decisions on the interior build.  In the meantime we need this bay to build the hull for Möbius.


One of the many benefits of being located in the Free Zone is the ready access to any amount of support equipment and services and so after taking down the surrounding scaffolding and clearing out all the materials that were surrounding the boat one of several boat moving machines was called in to relocate the GN47 elsewhere in the Naval shipyard.

This blue mover is the smallest one but plenty big enough for the GN47 and the operator, using a wireless remote control box soon had it positioned under the hull as you see here.

IMG_20180326_160435If you look closely in the foreground of this shot you can see the tread marks on the concrete floor of how the GN47 was lifted up by the hydraulic rams running down both sides of the mover and then deftly moved forward and around this corner where she will live while we are building Möbius.

IMG_20180329_115855This next size up boat mover is available for moving larger boats and this one is about the same length as Möbius.  Here you see one of the boats in the neighboring shipyard being moved from the yard where all her hotworks (welding) were completed and over to the yard where she will be fitted out with engines, props and systems. 

IMG_20180326_160444And Voila!  an empty bay ready to be prepped for building the hull. 

The first thing that needs to be done is build the jig as explained above and the next series of pictures will walk you through that process.

IMG_20180404_180729Because the jig provides the base for building the hull it needs to be measured out very precisely as indicated in the paper drawings you saw above.  Using a laser line sight, tape measures, etc. the floor is marked out to match the drawings from the model and holes are drilled to bolt the square steel plates you see here.

IMG_20180403_125740Concrete expansion studs are inserted and the base plates bolted securely to the floor.


Steel L or angle iron lengths ae cut and welded to each plate to provide the vertical supports for the jig base itself which will be made from CNC cut AL plate.


Each leg has been drilled for bolts which will secure the AL jig plates.


And soon the outline of the boats begins to emerge.


The first shipment from the AL supplier/cutter up in Istanbul arrives with the jig parts in the foreground and the very first set of AL pieces of Möbius in the back.  After more than two years of dreaming and designing Möbius is becoming real as I get to hold an actual physical piece of her in my hand for the first time!  But more on that in future posts, let’s get back to building the jig first. 

IMG_20180412_163656The AL jig parts are laid out on the floor and cleaned up ready for mounting on the steel legs.

IMG_20180413_172022IMG_20180413_172125Using the laser line level for heights and a sight string running precisely down the center of the hull, the AL jig pieces are bolted to the steel legs.

IMG_20180413_085109Here we are standing behind the hull looking forward so this is the aft deck area.  Keep remembering this is all upside down so that curve will end up creating the convex camber of the deck to assist with shedding water well. 

This aft deck area is about 7.5m/24ft long and about 5m/16ft wide and will be home to the large AL tender on the Port/left side as well as our outdoor eating area with sink, BBQ, etc.

The observant amongst you will notice the vertical slots in all the jig pieces and these are where the longitudinal jig pieces will be fitted and welded in place next week.


I climbed up higher to better see the overall size and shape of the hull at deck level.

If you remember the paper drawing above showing the side profile of the jig the raised section in the middle of the jig is about where the floor level of the raised Pilot House or what we are calling the Super Salon.  You will step down into the SuperSalon which is our primary living space having the galley, eating and lounge areas as well a main helm station at the front.

And that raised area as the jig moves toward the bow?  That’s where the deck steps down and slopes forward to separate the anchor deck area and make it easy to wash all the anchor muck off the decks and out the big drain and snubber hole in the very forward end of the bow.  More on all that in future posts.

IMG_20180413_171844This photo looking aft from the Pilot House aft provides a sense of size and scale to the jig and the aft deck

And that brings us up to date for Friday April 13, a very lucky day and milestone for Team Möbius as the jig is up and the building of Möbius truly underway.

NOTE:  We will divide the boat’s aluminium structure into two halves, the hull itself from the keel up to the deck as one part and then the second part will be the Pilot House and what we are calling the SkyBridge which are the structures which sit above deck level. What you are seeing in these initial videos is the preparation for building the first part, the hull structure and the second part will be built in a similar fashion in the bay on the other side of the one you are seeing so far. Work on the 2nd Pilot House structure will get started a bit later but both parts will be worked on simultaneously and then when the hull portion is flipped right side up the Pilot House structure will be lifted into place and welded to create a single unified structure.  It should all become clear as the build goes forward and cover all this in future posts.

VIDEO:  As promised at the top, I’ve put together a very rough compilation of different videos I shot over the past 2 seeks of the jig being built.  Apologies in advance for my extreme amateur videography, all new to me and I hope to improve as I do more for this project.  Möbius is not the only thing that is a work in progress, I am too!  So please do send me any and all comments and suggestions you have to improve any aspects of these posts. I can’t guarantee I’ll be able to implement them all but rest assured I will read them and use them to keep making this blog more useful and interesting for you.

Hope you enjoy the video and this blog as we bring you into the ground floor of the building of the good ship Möbius. 

It means a lot to both Christine and I to have you joining us on this grand adventure and I look forward to bringing you more as the progress continues.  .


The Jig is UP!

Boats are not the Only Thing Naval Yachts are Building

Lest you think that the building of our new boat Möbius is the only excitement over here in Antalya right now, it turns out that new boats are not the only thing Naval Yachts is building, they are also building a new building!  As in a new shipyard.

What you see in the photos here is the beginning of the new home of Naval Yachts with their brand new shipyard .  As you can see the previous building has been demolished and they have started laying the foundations for the new shipyard building.  This new site is only 2 blocks over from their current shipyard where we are busy getting going with the building of Möbius and promises to be one of the most innovative and forward thinking shipyards in the whole Free Zone here in Antalya Turkey.  In fact, it was because of the hard work and innovative thinking of Dincer and Baris Dinc, the two brothers who own and run Naval Yachts, that the Turkish government awarded them this entire block within the Free Zone as the winners of a close competition for the most innovative company.  With the synchronicity that seems to dominate my life, the building of Möbius  and the building of the new Naval Yachts shipyard both started at the same time.

I’ve taken a few more pictures over the past few days as the concrete work has progressed quickly as you can see below.

IMG_20171201_115818This is the current Naval Yachts building and shipyard and Möbius is being built in the bay behind the far left white door.  The door on the right of this photo leads into the reception area with offices on the floors above.  My new office, thanks to Baris and Dincer, is on the ground floor at the opposite end of reception and where I now go to work each day.

IMG_20171201_172323Moving just 2 blocks over however is this now empty lot after the previous building has been torn down and these metal barricades put up to enclose the new construction site.

Walking over to the diagonIMG_20171201_172137ally opposed corner you can see in the upper middle of the photo above I can show you this picture of the signage surround the construction site.

IMG_20180406_091410One of the signs is this rendering of what the new Naval Yachts shipyard will soon look like.  In the foreground of this rendering is the offices and some of the workshop areas and then behind this is a series of long bays for building future Naval boats and where Möbius will move once the new building is ready.  If you look really, really closely at this rendering you will see MiniMe versions of Baris and Dincer standing proudly in front of their future new home.

IMG_20180406_091419The other signage illustrates how Naval Yachts is comprised of three different divisions; Naval Studio which is focused on their work as naval architects and yacht designers,

IMG_20180406_091438Naval Yachts where they build high quality luxury yachts, and ….

IMG_20180406_091430GreeNaval where they focus on the design and building of hybrid and ultra efficient boats.  Up until now the GreeNaval yachts have all been electric powered hybrid boats whereas Möbius will be at the other end of the spectrum of energy efficiency using more traditional diesel power.  Yet with the careful combination of an extremely efficient hull design, engine and CPP propulsion system boats the likes of Möbius are able cross oceans consuming less fuel than the generators on a hybrid electric boat.  Two very different lines of boats for very different owners and uses but both on the same spectrum of ultra energy efficiency.

IMG_20180406_091519Work has been progressing rapidly in the weeks since those first shots of the empty lot above and on Monday this week (April 9, 2018) the digger had completed its work clearing the areas for the foundations, forms have been put in, rebar has been laid and ….

……. embedded PVC pipe runs for plumbing and wiring put in place.IMG_20180409_085232

IMG_20180412_095618Concrete work goes quickly so on the way in the Free Zone this morning, Thursday the 12th, I could see the concrete pumper was already on site

IMG_20180412_095614……………. obviously not his first time here as the first meter thick slab had already been poured a few days prior.

IMG_20180412_095611The workers in the background are busy wiring more rebar together to form vertical support posts for the floors above which will soon be surrounded by forms and ready for more concrete to be poured

You can now understand why, after quite literally searching the world for the Goldilocks “just right” boat builders to join forces with us and transform our visions and Dennis’ designs into reality, we chose Dincer and Baris and Naval Yachts to be our builders and transform our visions and models into a real boat.

Congratulations on all your hard work and the beginning of this new chapter of Naval Yachts Baris and Dincer.  Christine and I could not be more pleased for you nor be more happy for us in having found the just right builders and people to partner with on Project Goldilocks; the collaborative work of art and engineering named Möbius.

The Jig is UP!

Let the Building of the REAL Möbius Begin!

Things are a bit more subdued with the building of Möbius here at Naval Yachts this week as we await the arrival of the truck that is bringing the aluminium plates for the jig AND the first set of AL plate parts for the hull.  All the aluminium is coming from Istanbul which is about 800 km north of us and the current ETA is tomorrow or Thursday, April 11/12 so we are now all anxiously awaiting the arrival of the first batch of AL parts.

In the meantime, we were VERY excited to receive some photos (thanks Burak) from the AL supplier/cutter in Istanbul of the first set of plates coming off the CNC plasma cutter and wanted to share some of our excitement with all of you who are equally patiently awaiting the start of actual building.


As per the title, the cutting of the first plate of aluminium means that the building of the “real” boat has now officially begun!  I say “real” boat because for more than two years now we have been very busy working with our fabulous designer Dennis Harjamaa at Artnautica Yacht Design in Auckland NZ and essentially “building” Möbius as a very complete 3D computer model.  While never completely fool proof this process of building a virtual boat allows us to work through most of the design and building challenges before any physical materials are cut or purchased which is a huge savings in time and cost.  And by having a very detailed 3D model of Möbius which includes everything from all the many systems, electronics, controls, lines, anchors, down to all the wires and pipes and even our clothes and cutlery, it has been possible to run computer simulations of the boat in the water to determine everything from hull efficiencies to roll and pitch characteristics in different weather conditions to the boats reaction to a full 360 degree roll in the water.  I will no doubt bore you with much, much more of these fascinating details in future posts as I go over the whole design process so stay tuned for that, or maybe keep your finger close to the Delete key!


Hull plate cutting 8If you click to enlarge this picture you will be looking at the first set of AL parts from the first sheet of 8mm plate.

To help understand what you are seeing in these photos you will notice that in addition to doing the actual precise cutting of the AL plate, the CNC plasma cutter is also able to just lightly etch the plate to “print”  text names and alignment marks.  Thanks to Dennis’ hard work, each part has a unique name etched/printed on it to ensure that we can pick up any one of the hundreds of pieces in this giant 3D jig saw puzzle and know exactly which part it is by name and how it is oriented within the hull.  If you look closely at the picture on the left (click to enlarge) you’ll see the first 2 parts are Bow Stringer #6 and Side Deck S9.  Look a bit closer at Bow Stringer 6 and you’ll see an S near the bottom of the photo and a P at the corner above it.  S for Starboard (right side of the boat when looking forward) and P for Port side so there is no question which side is up and how it fits into the hull.  Looking a bit closer you’ll see two small tabs that have been cut just above each of these letters and these fit into matching rectangular slots which will be cut into the AL frame #1 to lock them into just the right spot and then be welded together.

Hull plate cutting 4This part is one of the transverse (side to side) plates down on the bottom of the hull which forms the grid of plates which become all our massive integral tanks for fuel and water.  For added safety and long range pretty much everything below the water line WL is tankage and therefore even in the highly unlikely situation where something manages to pierce the thick AL bottom plating of the hull, it only penetrates one of the many integral tanks rather than breaching the interior of the boat.  I’ll go into much more detailed discussions of all this later but to put it in perspective we have a total fuel capacity of about 14,500 liters (3800 US gals) and total fresh water capacity of about 5300 L (1400 USG).  While you can’t see the ID lettering in this photo as it is up and off to the sides, you can see two other important features of the CNC cutting process.  At the bottom center you can see one of the many rectangular slots which matches up with a notch in the thick (25mm) vertical keel plate which runs the entire length of the boat and locks them together in just the right spot.  Beside this center slot you will see a series of rectangles have been etched into the plate indicating exactly where the longitudinal stringer ends are to butt up and be welded to this transverse frame plate.  In most places on the hull these stringers run the entire length of the hull and so these rectangles would be slots for the stringers to interlock with, but in places like this where the plate forms the end of a tank on one side and an air “void” on the other side, we don’t want the stringers to penetrate the tank and thus eliminate any chance of a leak where these stringers attach.

PGL sketch 68In most cases throughout the hull though, where two parts intersect they do so via precisely cut and matching slots, half depth in one part and half in the other such that they interlock and automatically align with each other.

PGL sketch 67I will be able to show this to you much more clearly next week or so with photos as the assembly of this giant Erector Meccano set of a 3D puzzle starts to go together.

Hull structure details Dec 14-2017For now these quick screen grabs from the 3D model version of Möbius will give you a good idea how this works.

Hull plate cutting 6Here is the Rudder Shelf Top plate, or part of it, and that large precisely cut hole is where the thick walled AL tube will be welded in place to hold the very robust 128mm rudder post shaft.  The smaller two holes in the upper left of the photo are two of the 4 holes for mounting the Stbd steering hydraulic cylinder.

I mention these seemingly minute details because the intent of doing such a thorough 3D modeling of the boat is to have the CNC cutter do as much of the cutting as possible and thus minimise the amount of hand fitting that needs to be done during the build.  As you can imagine and will see more and more as we progress through the build, the savings of time as well as the increased degree of accuracy throughout the boat is dramatic.

As you follow us through our process of designing and building Möbius you will see how this focus on efficiency permeates every step of our journey so far with Project Goldilocks.  The examples above of achieving efficiencies with time and costs through computer modeling and CNC cutting are what emboldens us to take on this immense project.  And as I will cover in future postings, efficiency dominates our whole approach to this project to make it as affordable, safe and comfortable as possible to build, operate and maintain our awemazing new floating home.


For today though, the first Aluminium plate has been cut and the building of the real 3D Möbius has officially begun!!

The Jig is UP!

Scope & Scale: Antalya Free Zone

Many of you have asked for more information on the “Free Zone” and surrounding area here in Antalya where Möbius is being built at Naval Yachts shipyard and hence this post.  I’ll do my best to provide more postings over time to show you around the Free Zone, Antalya and this part of Turkey and the world in future blogs. 

* Note that you can click to enlarge any of these photos.

Related imageThe aerial shots above and below will give you a good birds eye view looking approximately SW over the majority of the Free Zone area with the Free Zone harbour in the distance.  The Free Zone and our apartment which is just off to the right of this photo are at the very western end of the large city of Antalya which makes for a great location for us as we are nestled up against those beautiful mountains you see in the background here and we can be on the D400 coast highway that runs all the way up that coastline you see stretching off into the distance at the top of this photo.

Image result for antalya free zoneThere are 2.2 million people in Antalya Province so the rest of the city stretches out for about 15km along the crescent curve of the coast to the East.  This photo is looking approximately East across the buildings of the Free Zone and you can see the first stretch of the city and the coastal “main street” going off the top.

The Antalya Free Zone is one of 15 that Turkey has created so far and you can read more about these at the Antalya Free Zone web site ASBAS.  Each Free Zone has been setup to attract very different kinds of businesses and as you can see for Antalya this has turned out to be large scale yacht and ship building.  There are several other industries here such as medical supplies and electronics but I’d say that more than 85% of the businesses and buildings filling up this 63 hectare area are shipbuilding.  “Free” in this context means that there are significant exemptions for any of the companies located here including:

  • 100% exemption from customs duties and other assorted duties.
  • 100% exemption from corporate income tax for manufacturing companies.
  • 100% exemption from value-added tax (VAT) and special consumption tax.
  • 100% exemption from stamp duty for applicable documents.
  • 100% exemption from income tax on employees’ wages (for companies that export at least 85% of the FOB value of the goods they produce in the free zones).
  • Goods can remain in free zones for an unlimited period.

You get the idea and so it is no surprise that many of the world’s top design firms for large yachts and ships chose to build their boats here.  We have chosen Naval Yachts to be our builders and as you see more of their shipyard below and the results of their work in upcoming posts, you will easily see why.

To give you a bit better feel for the area I thought I’d start with this short video I shot yesterday as I was leaving the yard and heading home from “the office” at Naval Yachts. Yesterday morning Christine was looking out one of the many corner windows we have in our nearby 10th story apartment (see map below) had saw this little guy docking .  Then as you can see it was rather hard for me to miss as I drove out of the Free Zone on my way home last night.

What you’ll see in the video is the harbour contained within the Free Zone where boats are launched, hauled out and worked on. I’ll do my best to provide more photos and videos over time and hope this quick 360 video of one aspect of the Free Zone would give you a better sense of the scope and scale of this place.  I will maybe mount the GoPro camera in the car and shoot some video driving around the various company shipyards here in the Free Zone but even in this short 360 video you can see several of the buildings of builders such as Damen and Ares.  And I’ll come back for more videos of this harbour/launching area over the coming months when other interesting ships are being launched or here to be worked on.  And of course Christine and I already have dreams of the day when we’ll be here to watch Möbius slip into these waters for the first time but that’s a ways off yet and we have LOTS to keep us busy and excited with the building process in the meantime.

As you might notice in the video the we have a rather lovely mountainous backdrop to this location as well. If you look closely you’ll see there is a cable car ride up to the café at the summit which is just on the other side of that cruise ship. 

Here is a small clip of a sat map that will show you the breakwater and harbour and the overall Free Zone area.  Our apartment is literally within walking/biking distance, the container port where our container is hopefully going to arrive soon as well as all the loads of supplies we need for Möbius is right beside the Free Zone and you can see where you catch the little gondola to go up to the top of that peak I mentioned in the video.

Free Zone sat shot Annotated

Continuing with the title’s theme of Scope & Scale let’s fly up a bit higher so you can see more of the whole indented coastline we are in the midst of.  Even this small shot shows the diverse geography and climates we are surrounded by.  Walk on the beach in the morning, gondola ride up to 2800m throwing snowballs at the top of Mount Olympus in the afternoon for Christine’s birthday a few weeks ago and back to the 5th largest city in Turkey for dinner.

Not a bad place to build a boat when you’re sandwiched between mountains on one side and a Mediterranean beach on the other and those were amongst the many factors which convinced us that Antalya Free Zone was the best place to spend the next few years building Möbius.
