I agree with Steve completely. The A-class and Tornado class cancel racing at 22 knots because they know that is the safe limit for the boat and the sailors. That's the reality of these boats and the wisdom of the sailors in the class.

If you really have a desire to sail a beach cat in over 25 knots of wind, just be sure you setup the boat for the conditions, have a life support system in place, and don't just go out to try it "for the hell of it". I've done a lot of high wind (+20 knots) sailboarding. It's much faster than any typical beach cat and way safer (when you fall, that board and rig is a sea anchor). You get seperated from a beach cat, you won't be able to swim near fast enough to catch it unless it turtles (I've seen this even in 15 knots of wind).
