Don't want a pickel fork? what I say? Our racing history included numerous spins, one rollover, one pich-pole, driver and co rider in the water numerous times, that's all in semi-v's. My little screw up was the only one in a tunnel and remember I'm talking racing history so we were all driving hard. For a river boat I wouldn't think twice about the hull as the best choice. My warnings are only to inform. I'm not saying that every time you turn the boat you have to go back and pick up your riders. What I'm saying is lateral G's are like in a car not a motorcycle. Any boat has it's limits I want everyone to drive within them I think those limits are better in a tunnel.
