Re: Fast Motorsailer mods
- Not trying to put you off, Ryan, but here is another consideration:
without increasing scantlings (thicker ply on the bottom?), will the
boat be strong enough with the extra section added? Five ft. is a lot
in a boat this size. Think of the forces at work when the hull is
supported in the middle by a wave, particularly if that wave is
moving at 20Kt or so. The trouble with flat sheets of plywood is that
they are not as rigid as sheets that are curved. There might not be a
problem unless you are using a large engine. PCB would have the

You need to think about (and possibly calculate) whether the hull
will trim correctly, at rest and while planing. You will be changing
the weight, the buoyancy and the dimensions of the planing surface.
With aircraft, I don't suppose you need to worry too much about
hydrostatics, or the hydrodynamics of planing surfaces either, except
with seaplanes or flying-boats.
