narrow rectangular punt (11'x2'x1') made of thin plywood under
construction. The bottom skids and gunwales are on. There are glued

screwed chine battens at the intersection of bottom and sides. Three
rectangular building molds are still in. When I torque one end there
is
too much twist (flexibility) in the hull for my liking.

I am thinking bulkheads, frames, partial decks, or some arrangement
of
stringers. (I opted for the shoebox shape for ease of construction. I
know
that curves would have been better.)

Any suggestions?


After you have a few of these under your belt you will find that they
stiffen up quite nicely once the seats, quarterknees, etc are put in,
provided the boat is properly designed and planned out before
construction...
