: Glue a few blocks of white styrofoam together and cut to shape, then

Hi Mark,
I have tried to respond twice now and I have lost my responce somewhere in space. Keep up the ideas. I will through in mine very quickly. I have found that the blue and pink building foam for homes is cheap and much easier to sand then white foam. I have also been able to bend it to shapes with heat guns if you are careful. What I have in mind is bending panels of it over tempory station forms with banks of heat lamps and weights on the foam to relax it to shape. I'm sure there are many things wrong with this idea but there it is. Once the boat is built this way, I would fiberglass the whole thing on the outside and then strip out the inside of foam machanically and chemically. Just a thought.
