This week Team Möbius made great progress on both on the bottom and the top of the hull of the hull. On the bottom Sezgin and Mehmet continued in what must seem to them as the unending miles of welding since all the hull plates have been tacked in place. Joining them on the floor Enver and Umit were busy completing the fin shaped skeg which houses and supports the propeller shaft. Meanwhile up on top Uğur and Enver were busy setting the first frames that make up the superstructure for the above deck Pilot House which wraps around our primary and largest of the three interior living spaces, the area we refer to as the SuperSalon.
This superstructure creates an eXtremely strong monocoque like cage that provides the framing for the 360 degrees of glass windows which wrap around the entire SuperSalon and the roof creates the floor for the SkyBridge above. The SuperSalon contains our Galley, Dining table and Lounge areas as well as the main Helm Station at the front and the stairs leading down to our Master Cabin forward and Christine’s Office/Guest Cabin aft. But enough already Wayne! Let’s get on with the pictures and video.
This foil shaped fin on the bottom aft end of the hull is what is called a Skeg and it helps a bit with keeping the boat tracking straight much like the fin on a surfboard but its primary roles are to protect and support the propeller shaft where it exits the boat and enters the water and to provide protection to the propeller and rudder aft from any debris that we might run over.
Seasoned sailors know from first hand experience that it is not IF you are going to run aground but when. The 50mm / 2” thick “shoe” you see in these two photos will be welded onto the bottom of the Skeg and add even more strength to the massively over engineered Skeg.
The bottom of the Skeg is also the lowest point of the boat so this is where the boat would first contact the bottom and we have built it to be eXtremely strong to be like the old Timex watch jingle “It can take a licking and keep on ticking”.
The center of the skeg is a continuation of the 25mm/1” thick keel bar that runs down the center of the entire length of the hull and the temporary support webs you’ve seen in previous posts have now been cut away so that the 15mm thick aluminium tube you see here can be slid in place.
Looking aft you can see how this aluminium tube has been pressed through the thick support webs and tacked in place.
Once the hull is all finished and we are fitting the engine and CPP propeller system, the CPP prop shaft log which is another tube containing the prop shaft, bearings and seals will slide inside this tube with about 12mm / 1/2” of clearance between the two tubes. Once the engine, CPP gear box and prop shaft have all been perfectly aligned the space between the two tubes will be pumped full of special “ChockFast” epoxy and form an eXtremely robust and well aligned propulsion system.
We call Sezgin away from welding the hull plates to lay down these beautiful welds to complete the prop tube installation and get ready to fit the thick plates that will form the slick foil shape of the Skeg.
The two 25mm thick beds for the engine and CPP mounts are running horizontally on either side of the Skeg and if you look closely (click to enlarge) you can see the end of the prop tube where it enters the Engine Room on the left.
While I’m up here, this shot looking a bit further aft into the Workshop area behind the Engine Room shows the arc of the prop tunnel from the inside.
Further forward Sezgin our Master Welder continues his non stop welding of the 15mm/ 5/8” thick hull plates.
Mehmet works both before and after Sezgin to initially prep all the areas to be welded by grinding them clean and well recessed and then follows up by cleaning the thick final welds which Sezgin has laid down. They are certainly getting a workout now that much of their work has to be done overhead but they are always smiling and enjoy seeing all their great progress.
This shot looking towards the bow shows most of the different phases of the welding. The dark rows extending forward on either side of the center keel bar are the temporary bridges tacked across the seam where the two hull plates meet to keep them perfectly aligned during welding with that ceramic backing taped in place as you’ve seen in previous posts. Coming aft of Sezgin’s left shoulder is the finished beads of welding he has laid down where the hull plate attaches to the keel bar
Back at the stern there is new action as Uğur passes some of the previously welded assemblies up to Enver on the Swim Platform. Wonder what they could be for?
Ahh yes, the truly super structure that wraps around the SuperSalon. First they carefully align the vertical I beams with the stub ends of the hull frames that were welded in as part of the first phase of building the hull when it was upside down. You can see two of these stub ends behind Ugur’s back to the left side here.
The frame in the foreground is the aft end of the SuperSalon with the WT door to the steps leading inside with the Galley on the Starboard/Right side.
Moving up to the foredeck looking aft through the SuperSalon, Uğur is prepping the long plates that will form the underside of the roof overhang of the SuperSalon and getting ready to tack the front window mullion posts in place.
The four vertical posts up on top of the frames are the beginnings of the framing for the coaming that runs around the SkyBridge atop the SuperSalon.
You can see how all the windows are negatively raked, bottom in further than the top which is a feature we picked up from all the Pilot Boats we visited and pretty much eliminates reflections on the inside and reduces the rain drops on the outside.
Hopping down into the SuperSalon I can now check out this view from the inside.
Can you imagine what this will look like when we are in some lovely little anchorage with nothing but tropical turquoise seas and beaches outside all these windows! We sure can!!!!
Sezgin has finished welding up the inside area round the snubber nose cone. All the welds exposed above the waterline will eventually be carefully ground flush and smooth to create a uniform and smooth surface.
And just before we go, a few photos to give you a quick update on the equally great progress being made a few blocks away here in the Antalya Free Zone with the building of the new Naval Yachts shipyard.
The ubiquitous crane trucks are being kept busy as the framing for the shipyard building goes up.
As always we’ll finish up with your reward for getting all the way through yet another of Wayne’s posts with a quick time lapse video summary of this week’s progress.
