Summary:Provided is a ship in which fuel efficiency is improved while a reduction in the propulsion efficiency of a propeller is suppressed. Also provided is a ship cleaning method. The ship (100) equipped with ballast tanks (10) for storing ballast water is equipped with a propeller (1) and a water jetting means (2). The water jetting means (2) jets water toward the propeller (1) if the propeller (1) is at least partially exposed at the water surface. The ship (100) is also equipped with a control means (50) for controlling the water jetting means (2). The control means (50) controls the water jetting means (2) in such a manner that water is jetted toward the propeller (1) if the propeller (1) is at least partially exposed at the water surface.
