Mick, Interesting idea. I would like to see pictures of the assembly (and the beer support!) If you try to build as fast and cheap as possible, the single boxbeam method is unbeatable in the long run (1/2 sheet of plywood only!). Stiffness IS the main issue if the whole kayak (a sheet of particleboard and the spine itself) bears down on a 2x4 or 2"x5" box beam. The A frame I was referring to are just two prop-up sticks duck-taped together so that they don't spread apart. It takes 10min to set-up. This is only necessary until the hull is half way done.
