The plans don't specify the ply thickness?

I've only built one S&G boat - a small pram - but I would not want to
try building one with anything thicker than 1/4" for sides/bottom
because of the difficulty in getting it to conform to the compound
curves. And those curves are what makes the hull stiff. That and
gunnels.



The plans are for traditional plank construction. I'm doing the
conversion to S&G.

This is a square chined boat, with bottom and side panels only. The
warping required is minimal except for the forward-most part of the
bottom panel at the base of the bow, where I plan to cut the bottom
panels short and carve/saw out a solid block to make the final 16" or so
transition to the stem (they have to do this in traditional construction
of these boats as well, as those thick juniper planks can't make this
severe transition either).

So I think I can do the warping necessary with either 3/8" or 1/2" ply
on the bottom panel, the question is do I need the strength of the 1/2"
there, or can I get away with the 3/8".
