Abstract
It is an object of the present invention to reduce a restriction caused by a water depth of an area available for sailing. The ship has a hull part and is configured to be able to sail on water. The hull part has: a fuselage extending in the longitudinal direction of the hull part; a keel and a rudder arranged on the fuselage to receive water flow when the ship sails; a first posture switching mechanism for switching the postures of the keel and the rudder between a first posture and a second posture; and a first power source. The first posture is in the keel and the rudder respectively extending to the lower side of the fuselage. Compared with the first posture, the second posture is shorter in the length of the keel and the rudder when extending toward the lower side of the fuselage.
