Since we’ve been boring you with technical posts all week why change the rhythm? These photos are from Friday, and cover FPB 64s five through seven. We’ll start with seven, shown above, the skeleton of which is just starting to be assembled.
These structural elements are cut on a computer driven device that adds alignment marks for assembly as well. There are welding jigs for each of the prefabricated items, like bulkheads and tank tops, which insure accuracy and speed production.
All of this starts as a 3D model of the complete boat, which is then dissected into cut files. The furniture is designed to fit this same 3D model, which minimizes fitting time (and mistakes). It is this potential efficiency, harvested by Circa’s experience in production, that makes it possible to build to such a high standard yet keep costs moderate. Absent this approach, the price at this quality level and specification would easily double.
Moving on to FPB 64-6, the metal work is nearing completion. We are looking here at the two prop skegs, main on the right and get home, framed but not yet plated, on the left. Both share the same framing and plating scantlings.
Inside the engine room, the prop shaft tube (log) for the get home engine. Note the sump, which slopes down towards the bow, and drains to the main sump. This detail reduces constant wetness from pooling of drips under the “dripless” shaft seal.
The house structure is now welded in place.
Note the structural connection of the house roof assembly. The corner and side window mullions are captured at the top of the coaming, at the deck, and then down the topsides with a partial frame to the upper topside stringer.
Finally, a series on FPB 65-5, starting with this look up at the headliner panel grounds (attachment points).
Looking aft towards the entry way and galley. The large locker at the top of the stairs, formelry for jackets and foul weather gear, is now dedicated to the galley.
The oven will live at the bottom, and then the rest is available for general storage.
Note the angled pipe in the pantry locker which goes to the exterior for mast wiring. The angle downward is to assist any drips in returning to their native environment, rather than visiting the interior where such malevolent entities are most unwelcome.
Bulkheads, furniture grounds, and what will become covers for structural members and raised deck edges are completed in the aft guest cabin. Note the aluminum cable trays. These will shortly be well populated.
And last, the get home engine with its V drive (bottom of photo), thrust bearing, and engine,
