How about UIM F1H2O boats? Never heard of them until I happened to watch a championship race on the BEIN tv channel. I saw the GP of Zhengzhou China. Here’s a YouTube vid, jump to 15:00 to see them ‘cornering’. They’re 20’x7’ dual tunnel boats with enclosed cab forward cockpits. They’re made out of Kevlar and carbon fiber and weigh less than a Gold Wing including the Mercury two stroke V6 outboard that generates 450 ponies @ 10,500 revs. 150 mph top speed and 0to62 mph in less than four seconds. At speed on the straights, only the rear foot and a half is in the water with the pilot finessing the ‘rise’ forward just enough to keep them from flipping over. They corner like an F1 car, chopping the throttle which settles the twin hulls and then wham, they turn 90 degrees. Then wham, back to full throttle. Very exciting racing especially when the boats are close to each other.
