Think triangles. Strips of cardboard folded into three sided tubes are
quite strong. Use for chine logs, sheer clamps, and thwarts.

I figured a triangle along each of the sides (top and bottom if I have
enough) as well as three horizontal stabilizers should help
considerablly with the over all stability of the boat.

See my other post as well. I ranted there about canoe vs single sheet
etc....




Get one of the gadgets that put the rubber retaining strips back into a
screen door. You can crease and fold across the corrugations where needed
without cutting the paper.

Great Idea. Thanks. I'll stop on the way there and get one!

Duct tape!

Provided, and can be the only type of adhisive etc...

Bathing suit.

but if I build it correctly, I shouldn't get wet right?

I got myself singed up for a cardboard boat race this saturday. We
are given two sheets of 5x8 card board, duct tape and plastic
sheeting. I was thinking of building a canoe style, but was worried
about the boat folding in half. I know plywood has alot more
stability than card board, and was wondering if anyone has had
expirence in this area, or could point me to a web site that might
offer help. I don't know how big the plastic sheeting is, which is a
problem. I don't know how long the boat could be. I was thinking
along the lines of a D4, or a 12' canoe, but made a bit wider for
stability.

Playing around in the hulls program (great program!) shows me that for
one person, displacement isn't as much of a concern. My main concern
is of the plywood folding around me when I sit in it.

Any hints?

The race is Saturday.
