In order to avoid erosion phenomena on a rudder which appear due to cavitation formation, in particular for high- speed ships with high loaded propellers, and in order to reduce or maintain low the fuel consumption, it is provided, for a rudder for ships comprising a rudder blade which shows a leading edge and a trailing edge, whereby the rudder blade has two superimposed rudder blade sections, the leading edge sections and/or the trailing edge sections of which are offset in such a manner that the one leading edge section and/or the one trailing edge section is offset port or starboard and the other leading edge section and/or the other trailing edge section is offset starboard or port and that the one leading edge and/or trailing edge section has a port-sided offset surface which projects over the other leading edge section and/or the other trailing edge section and the other leading edge section and/or trailing edge section has a starboard-sided offset surface which projects over the one leading edge section and/or trailing edge section, a flow body configured in such a manner that its dimensions are adapted to the dimensions of the offset surfaces, which covers the offset surfaces and which is configured in the area of each offset surface.
