The present invention is directed broadly to an underwater appendage assembly (10) of a marine vessel (12). The underwater appendage assembly (10) is in the form of a rudder assembly fitted to a bow section (14) of the vessel (12). The rudder assembly comprises an appendage in the form of a rudder foil (18) connected to a flapper member (20). The flapper member (20) is arranged whereby movement and more particularly pitching, of the vessel (12) induces deflection of the flapper member (20) relative to the rudder foil (18). This deflection in the flapper member (20) provides an oscillating movement of the flapper member (20) in a flapping action which is substantially synchronised with movement of the vessel (12) upward and downward. The flapping action of the flapper member (20) is effective in promoting forward propulsion of the vessel (12).
