You can buy a jetski. Or a boat. But why learn how to pilot a new craft when you already know how to drive a car? The Wavekat P70 Personal Watercraft uses the same steering wheel and foot throttle as your car, making piloting it as simple as sitting down and driving. It relies on an asymmetric catamaran hull design for a stable ride, lets you make sharp 90-degree turns with virtually no loss of speed, and has a top speed of over 35 knots, or more than 40 mph.
