A water borne amphibious vehicle having a fuselage generally formed to provide a low air resistant surface and aerodynamic stabilizers, and at least one flotation drive wheel of generally spherical shape of sufficient size and buoyancy for supporting the vehicle in water and mounted for rotation beneath the body. A plurality of drive fins are formed around the wheel extending from either side of a vertical circumference of the wheel and are constructed and arranged not to extend above a plane tangent to the surface of said wheel at any point on said vertical circumference. In one embodiment a hollow inflated flotation drive tube forms a closed loop "V-belt" drive between the vehicle motor and flotation drive wheel.
