Abstract
A propulsion system capable of more efficiently accomplishing all that the prior art propulsion systems can accomplish and additionally providing for maneuvers that had hereto been unavailable with purely stern-driven craft through the use of a first and second method for generating propulsion mounted at the rear of the craft to be driven. The two methods for propulsion are arranged one over the other so that the centerlines are substantially aligned vertically. A movable rudder is mounted substantially vertically at the rear of the craft parallel to the centerline of and in the effluent streams of said first and second propulsion method. A fixed fin array is also mounted at the rear of the craft in the effluent streams of said first and second propulsion method just forward of the rudder.
