PURPOSE: A marine rudder and a ship including the same are provided to effectively offsetting the rotation element of a propeller race and rudder bulb by forming a surface area distribution rudder bulb which is proportional to the intensity of the rotation element of a propeller race. CONSTITUTION: A marine rudder comprises a body(52) and a rudder bulb(54). The body is rotatably installed at a hull in the back of a propeller. The rudder bulb is installed in the body. The leading end of the rudder bulb is located on surface the central axis of the propeller. The section in which the race speed of the propeller relatively fast between the left area of the rudder bulb about the central axis of the propeller and right area is wider surface area than the other area when looking at the front. |
