Re: Pros and cons of steel sailboats
The term that I know is 'tortured plywood'. As we know, plywood (and plate steel a use in origami construction) is really only able to produce 'conic sections'. While steel can be formed into compound curves, plywood normally cannot be twisted into compound curves.
Tortured plywood uses thin layers of plywood, and some framing to force the plywood into mildly compound curves. It was pioneered by the folks doing plywood multihulls, but you see it in other narrow hull forms such as kayaks and in boats with minimal rocker such as high performance skiffs.
