We know this is now a car, but it might as well be. Its fast and its crazy, and thats why we love it. Hydroplane Boat Racing, is one of those sports that dangles right on the edge of physics, messing with dowforce, thrust, and a range of other elements, pushing everyone of them right to the limit. And what this means is that when something goes wrong, it goes wrong in a big way.

Its a pity no points are awaked for awesome backflips, cos this one is pretty cool.  Check it out
