Trying to imagine the least weight way to reduce twist in a light weight
narrow rectangular punt (11'x2'x1') made of thin plywood under
construction. The bottom skids and gunwales are on. There are glued and
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?
