The pod propulsion unit includes a pod propeller; and a strut. The main propeller and the pod propeller configure a contrarotating propeller. When rudder angles of the pod propulsion unit and the rudder plate are zero, at least a part of a front end of the rudder plate is in front of a rear end of the casing.
