Amazing: Seabreacher

This half jet ski half dolphin contraption allows people to drive a boat like never before. The Seabreacher drives at 40 miles an hour and allows users to do barrell roles, small jumps and other tricks.
I hadn't even considered something like this before and I'm sure ideas used in this will push boat technology further.
