Abstract
An apparatus for enhancing the steering effect of ship rudders comprising a rudder with at least one passageway for supplying seawater to ducts in the rudder, and a profile element extending substantially vertically at a leading edge of the rudder and being pivotable about a generally vertical axis, wherein distribution ducts formed between the profile element and the rudder communicate with the passageway and are adjustable so that relative movement of the profile element and the rudder causes seawater to be discharged along the rudder surface facing abaft.
