: A longer boat would be faster, and it could be made slimmer, too. The problem
: with making a longer boat would be that you need either longer materials,

I have until June to build it and have no limit on the budget. The only materials allowed are cardboard, tape, adhesive/glue and sealant/paint. I have some real solid construction techniques (last year's boat is still fine!) and use lacquer inside and out for waterproofing. I can get cardboard in 4ft x 8ft sheets so material is not a problem. On last year's boat, I tapered the bottom of the bow so that the tip of the bow sits 2 inches higher that the rest of the bottom of the boat. Did this help, or hurt, or have no effect?
