Abstract
A lift-producing arrangement suitable for driving a boat by the Magnus effect comprises an elongate tubular envelope mounted for rotation about its longitudinal axis. A drive is provided to rotate the envelope. The envelope is of flexible material, e.g., canvas, to achieve improved performance. Preferably, the envelope is held erect by inflation. The arrangement may be used in addition to a conventional screw-propulsion system for increased fuel economy.
