Have done it, no problem, we are arguably a "overweight" team though, and I'm not sure the mast really liked what we were doing to it
Double handed, 25 knots flat water is very doable, and a lot of fun. Add in heavy seas / lake waves, not as much fun.
I'm more for a limit to how many races a day, as it minimizes the time on the water in heavy air (also limits the damage that can be done to one score in conditions that are not suited to you). IMO the biggest safety concern is when you race too many races in big breeze. One is fine, but as you start wearing down the strength of the crew, things go tits up fast.
22 seems low for double handed, but understanding the fleet allows single handed, I see why it is chosen.
F16 under spin in 25 knots. I doubt if there are six crews in the WORLD that could handle that much wind, and stay on course.
There may be a lot crews that could go blasting off down wind, but: round a mark, set the chute, drive to a gate, retrieve the chute and head back up wind. I gotta see it...
