Sounds like a crazy place to run a boat. That must be hard to pick a day to go out and have fun, running or fishing. How often do you get good days? In that kind of weather you would be better off cruising at normal speeds in the 70 mph range. Or just trolling. I have never had any time where one sponson lifted, the boat is a little heavy for that. I guess that can happen in smaller boats like stv's. I have never had anyone tell me they have that problem in our boat. But 20mph winds with 40mph gusts is not a good place to be running fast, in any boat, I would not be comfortable in a 50' boat in those conditions. It might be a little scary to have trees falling in front of ya too (holy cr#@). I think I'm going stay in Fl.
