What Bacho posted is what I recall reading. There isn't a rule that I'm aware of that stops them from going over 50 (as in, the blue light won't flash).
I think these boats are faster than expected, so I'd be surprised if they're not capable of getting over 50, if the wind is close to the limit and the water is flat enough.
I also don't know why cavitating is something they need a wind rule to prevent. If the foil cavitates, won't the boat just slow down? Seems like a self-correcting problem, or is there a safety issue I'm missing?
