Abstract

Propulsion system, particularly for high-speed boats (5), consisting of a propeller (3) having a propeller hood (4') positioned downstream relative to the propeller blades, and a rudder (7'), and where the propeller hood (4') extends entirely or partially along the lower edge of the rudder (7'), and where the rudder has approximately the same cross section as an airfoil or aircraft wing. The propeller hood is preferally designed as a cone or as a rotating body the generatrix of which forms a curve. <IMAGE>
