Marine ball drive comprises guide rings adjusted to drive vane sides plus drive shaft carrying drive and buoyancy elements and slide surface below remaining immersed at high speeds.

摘要

The invention relates to a marine propulsion system and describes a marine propulsion system with improved efficiency, which leads to reduced wave formation, comprising an at least partly submerged forward propulsion unit, rotating around at least one axis, running essentially perpendicular to the propulsion unit and a cover, at least partly enclosing the propulsion unit, which, on operation of the propulsion unit, forms, together with the propulsion unit, a flow channel, delivering the water.
