Machine-driven propulsion system for vessels where the propulsion force arises from a high-speed vane wheel having cup-shaped vanes open in the direction of rotation. The vane intake is provided with a cutting edge which penetrates down into a stable water surface beneath the vane wheel and brings up a defined amount of water which is strongly accelerated astern by the inside of the vane. The reactive force against the inside of the vane produces the propulsion force.
