The vehicle can be referred as a type of speedboat, because it is designed for very high speed on water. Preferably, the vehicle consists of a hollow shell 1 of circular section that floats and spins on the surface S of the water. The engine 2, which also includes the cabin, is located inside the shell 1. The output shaft of the engine 2 drives the shell 1 about axis O. As the shell 1 spins, the viscous forces between the spinning surface of the shell and the liquid, cause movement of the vehicle. Means of preventing counter rotation, of the engine 2 inside the shell about axis O are included. This is provided by the weight of the engine, which hangs low and off-centered about axis O; and by the aerodynamic uplift acting on the tail 3, through the lever arm action on the frame of the engine 2.
A watercraft comprising of one or more dynamic bodies or components, partly immersed, equipped with blades or paddles on the external perimeter that are in contact with the liquid element, rotating about an axis perpendicular to the direction of travel of the watercraft and driven by an engine, whereby the non-rotating part of the engine is connected to a means or mechanism that produces a counter-torque so as to prevent rotation of the non-rotating part of the engine when the dynamic bodies are rotating.
A watercraft substantially as herein described and illustrated in the accompanying drawings.
