Peter Van Dyne of Annapolis, MD built a number of sail boats from 16 to 40 foot using this same method. He used polyurethane (PU) foam ripped to 1" x 1" x 8' long and laid them up over a hull form just like strippers use only bigger. He used toothpicks to "nail" each strip to the previous one. Faired them out and lightly and carefully glassed them inside and out. (Peter is the guy who taught me that you NEVER need to sand the glass itself if you perform your layups carefully). His methods produced very light boats but not real durable. The ones he built using 2 pound density refrigeration foam (green) where feather light but had delamination problems because the "edge strength" of the foam was not high enough. Even the 4 lb denisity foam (reddish pink) boats had problems, but that was because they were so lightly glassed and were easily holed or dented. If you took care of them though, they were and are great boats. Very light, high performance even though many of his designs were throw backs to old fashion designs. It was such a gas to watch his little Tancook Schooners wipe up on big racing boats. Peter was an excellent designer/builder, way-way-way ahead of his time. He got bored with boats in his old age and went in experimental aircraft design and building. I think his foam strip & glass method would translate perfectly from wood/glass to foam/glass construction. The right foam to use is an important question. I'd consider using a 4 lb PU foam like the white stuff that is used to make surf boards (what we used to call Clarke Foam). This is available in sheets of various thicknesses from the aviation supply companies like Wicks Aviation. 3/8" sounds like about the right thickness.

- Why not stripper with strips cut from foam ? *NM*
