ABSTRACT OF THE DISCLOSURE The present invention relates to a rudder for ships travelling in ocean areas where there is a risk of ice and whose rudder blade end is provided with a lift prestress profile, which is constructed as a symmetrical thickened or widened portion and which has at its profile end an ice cutter tapering in blade-like manner towards the end. Upstream of the rudder blade, whose leading edge can carry a rotor, can be connected a fixed guide head, which can also be frontally provided with a rotor. As a result of this measure the rudder action is improved and it is possible for the ship to move astern in the ice.
