what are the limits of plywood boats ?

I am interested in kind of ultralight (25000# to 32000# light) trawler in
the 42-50 feet range, of displacement type, not semi displacement. No intend
to exceed hull speed. So single engine could be in 100-120 hp range.

Plywood construction, easy to build. My father is a retired woodcrafter, and
I found at home an original copy of heavy weather sailing by Kadlard koles.
He has owned several sail boats, but never powerboat and never built one.

But, except Argosy , Klondyke from GlenL, I found nothing.

The study plan seems to show that they are not very up to date. When you
need three layers of plywood, one may be worried about real developpability
of plates. Also planned wood and size does not seem to be what is currently
done and cost efficiently available.

Thanks in advance.
