I have made a Freeship model of the hull I am interested in.

This is not the 100% final version, just a close approximation. The idea
is basically a extra-wide rowboat hull with a very flat bottom. There
will be a flat sealed floor set 6" above the hull bottom on frames
spaced every foot.

This is a inland/fla****er boat only.

I would get it rated for a small motor, 5 HP I think. Not very fast, but
as light & broad as the hull is, it's just not going to be safe going
fast anyway. Other 14" boats seem to be running 20-30 HP regularly. 10
MPH is okay for this, I just need a motor that's "faster than rowing"
while being and "less effort than rowing".

One 14" commercially-made boat I found used 2mm (~.078") for the hull, I
dunno what alloy. I have no idea how thick to go for the floor. I think
the usual sheet the local metals supplier has on hand is 5052.

,,,,Coincidentally [if you are a USA poster] I cannot find out how to
rate a home-built boat for horsepower on the USCG website. I found the
home-builder's handbook stuff, they go into all the math to find hull
displacement and determine gear and passenger capacity and they have a
table giving weights for engines of increasing sizes,,,,, but they say
nothing about how to decide how much power to hang on a boat. Is there a
formula for this, or is it just--you ask for as much as you want, and
they make the final call?
