: I need to make a boat for a
: recycled boat race. I'm thinking a Kayak design might win it for us this
: year (other designs have been way to heavy).

Once saw --- and attempted to paddle --- a "Greenland" design single made from recycled foam panel insulation, held together with glue. It was built (very roughly) to Chris Cunningham's Greenland kayak design in an old Sea Kayaker magazine. The only serious problem it had was that it weighed about ten pounds and needed some ballast just to get it to keep from sitting on top of the water. Taking some liberties with Chris' (non-licenced) design to make it a double might not be too difficult it you're looking for a reasonably quick craft but not necessarily an open ocean-capable expedition boat. Cost should be limited to the glue if you can find some foam insulation at a demolition site.
