t is disclosed herein a 4-wheeled sea vehicle which, in comparison to ordinary crafts, economizes combustibles, and exploits the minimization of the hydrodynamic resistance for improving final speed, acceleration, manoeuvrability, immobilization and safety of the vehicle, while travelling. The invented sea vehicle is able to float onto 4 unsinkable wheels and roll over the surface of the sea and not in depth. At a speed exceeding the 50 mph, the wheels are elevated and "licking" the sea surface by reducing the hydrodynamic resistance to a minimum so that the final speed is increased. It is an all-weather vehicle with wheels having internally independent waterproof compartments for greater safety. Furthermore, danger of reefs encountered 1/2m under the sea surface is abolished. The rear wheels acting as drive wheels have especially shaped shoe helping the propulsion of the craft. |
