One or more propulsion arrangements for water vessels, and in particular propulsion arrangements that include flanking rudders with bidirectional high-lift sections to improve performance, particularly in the reverse direction. The flanking rudders are positioned adjacent a propulsor for directing a slipstream flow when the vessel is travelling in the reverse direction. Each flanking rudder has an elongated profile extending from a first edge to a second edge, and in which each elongated profile has a first bulb portion, a convex middle portion, and a second bulb portion.
