Gibbs Aquada
If your need to get across a body of water is high enough, and you don't mind maybe getting a little wet, the Gibbs Aquada may be your answer. The Aquada is the world's first High Speed Amphiban, capable of going over 100 mph on the road and 30 mph in the water. Driving into the water is as simple as going down a gradual descent and pressing a button to make the wheels automatically rise and pushng down on the accelerator to generate thrust to move. You can even tow a water-skier if you want.
