The invention relates to a rudder for watercraft with a stabilizer (13) articulated to the rudder blade (11), the stabilizer and the rudder blade being connected in articulated manner by articulated blades and several connecting bolts. The in each case upper articulated bush is supported on the in each case lower articulated bush, accompanied by the interposing of a self-adjusting, annular centering device mounted in free-floating manner and taking up the axial weight.
