Abstract

Mechanism for dynamic trimming of the floating position of a planing or semi-planing ship hull during operation thereof, including a plate (3) that is submerged transversely to the relative water flow directly behind the bottom of the hull for generating a vortex (V) having an upwardly and forwardly directed velocity component in front of the plate, thereby creating a water volume having an increased pressure that is acting upon the portion of the bottom which is positioned in front of the submerged plate. The plate (3) is continously adjustable to a desired depth through actuating members (8) and is vertically displaceable and supported in the lowermost portion of the stern plate of the hull.
