A ship includes a main propeller 20; a pod propulsion unit 30 steered by a first steering mechanism 11; and a rudder plate 40 steered by a second steering mechanism 12. The main propeller 20, the pod propulsion unit 30 and the rudder plate 40 are arranged on a hull centerline. The pod propulsion unit 30 includes a casing 31; a pod propeller 33; and a strut 34. The pod propulsion unit 30 is arranged behind the main propeller. The rudder plate 40 is arranged behind the strut. The main propeller 20 and the pod propeller 33 configure a contrarotating propeller. When rudder angles of the pod propulsion unit 30 and the rudder plate 40 are zero, at least a part of a front end 41 of the rudder plate 40 is in front of a rear end 31a of the casing 31. Thus, CRP (contrarotating propeller) effect can be maintained at the time of high-speed sailing, and the increase of resistance due to a rudder provided except for the pod propulsion unit can be restrained.
