yeah....I'm going to call b.s. on the 100knot suggestion...anything sticking out of the water would be tumbling away. Having begun to stick my head up beyond a motorcycle fairing at 125mph, I can attest to the fact that youre certainly not going to be doing anything related to "sailing" at those wind speeds. Flying, maybe. Sailing, no. I can't imagine that you could keep a catamaran or dingy upright in anything above 45 - 50knots sails or no sails.
