Maritime Flight Dynamics wants to make high speed travel on the seas practical, safe, fuel-efficient and hell, while they’re at it, comfortable too. Their vehicle of choice? The SeaPhantom. It’s fast enough to get you from Key West to Cuba in 45 minutes! It uses an airfoil to fly above the crests of the waves, thus reducing drag.
The propeller remains in the water, while the body of the SeaPhantom is above the sea’s surface. Apparently this reduces hydrodynamic drag and in doing so, requires less power and uses only a fraction of the fuel compared to conventional fast boats. And we may have a chance to ride in one ourselves very soon since the Sea Phantom has moved from prototype to the actual ocean. It looks like a robot killer whale.
