The F31/C31 has very narrow ama sterns -- very little flotation aft. This lack of buoyancy toward the aft quarter could make the boat more vulnerable to a capsize if you're overpowered while beating -- blowing the boat over backward and to the side. If overpowered bear off QUICKLY and run off to reduce apparent wind -- don't round up. The quickly executed turn will also throw the weight of the rig to windward (centrifugal force) to help counter the gust (dynamically, just for a few moments). Think about it. You won't have time to think when the situation warrants.
