Rudder has rudder blade (100) which comprises a fin and two superimposed section. The propeller (220) turned to front leading edge is transferred in such a manner that one leading edge transfers after the port side and the other leading edge transferred after the star board. The two side panel surfaces of the rudder blade run together in the propeller to turn away the trailing edge. The rudder spindle (140) in its end area with a section is led out from the rudder trunk bearing (120) and the end of this section is connected with the rudder blade. No bearing is provided between the rudder blade and the rudder trunk bearing. The connection of the rudder spindle with the rudder blade lies above the centre of the propeller shafts. The inner bearing for the bearing of the rudder spindle is arranged in the rudder trunk bearing at the end area of the rudder trunk bearing. An independent claim is also included for the rudder blade.
