Is ultralight trawler not a contradiction?
The boats you list and that some propose are all heavy as a trawler shoudl
be.
How about a large dory? D. Gerr and G. Bhueler have designed some nice ones.
Reuel Parker too.
That would be much easier to build, less expensive, lighter. A 50' dory
would move nicely with a 100 HP engine.

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.
