Re: C12 question for Jacques

In the middle and as low as possible but you still need spreaders were the plans show the two seats. The boat is symmetrical but you could decide that one end is the bow and put a single seat a little aft of the middle (8 to 12") but with the seat in the middle and your gear behind you, the hull wil...

Re: TX-18 Build, Steig

Email and I will give you a copy of the hydrostatic calculations for the TX19. Those pages will show you the LCG and other values for the original design, you will have to scale them. Flotation is a volume of foam corresponding to the designed displacement or more or less, you decide but that displa...

Re: C17/C19 Question for Jacques

There is a cabin version of the C19, it is called the CX19. That cabin does not have a pilot house part but it should be easy to extend the cabin sides and add a windshield and roof. The C17 plans show the developed panels for the pilothouse but those panels would not fit the CX19. The best way to a...

Re: Preparing for GT27 build - questions

The transverse cross beams are 3" high. If you want to install the optional longitudinals, I would use a 1x2 nominal which is 1-1/2" high on edge, in a notch and glued plus fillets.
I don't say tape because it is impossible to tape on the ceiling. The fillets will be enough anyway.

Re: SOBX Little Big Boat GV15 build questions

Should I cut the second ply layer to match the called for clamping board or make it full size? Should I offset the two layers (or perhaps bevel them) to make the glued up assembly better match up with the hull’s bottom? Should I glue the two layers before stitching them onto the hull or add the sec...

Re: Preparing for GT27 build - questions

It all depends . . . If the roof was made of foam sandwich, I would build her as Fallguy describes. Foam sandwich is great for insulation and stiffness but as designed, the roof is a thin sheet of 6 mm. It is fine as a roof, it will not collapse even with the increased span as long as you don't inte...

So no owner or ride reports? Most curious to know if it will be suitable for my kids to use and learn on.

I know it is a design for a purpose. There will be compromises.
Hundreds of Phantoms were built. For example, do a search for posts by stickystuff. He built 3 of them.

Re: Preparing for GT27 build - questions

I will reply in detail within 2 days. Right now, I am at sea typing on a small tablet. Yes that angle is aesthetic, you can change it. For the roof beams, it al depends on what you expect from that roof. If you plan to store a dinghy on it or install lots of electronics, we must discuss it. As a sim...
