I know the safe way to go is stopping at 22knots on a A cat,

But there are some smaller sails available for 22knots+

I myself stop at +/- 30 knots on my Nacra 6.0 .

Anything above there is almost no one on the water to rescue you in case of an emergency.

Also you should consider are you sailing on a lake or at Sea there is a big difference from the impact of the waves to your material.
