To provide a vessel that can navigate in a desired direction solely by the operation of its wind-powered propulsion system. [Solution] The vessel 1 is equipped with a plurality of rotor sails 10 (wind propulsion units) provided on the hull 11. The vessel 1 also generates a turning moment TM (see Figure 2(b)) using the plurality of rotor sails 10. By generating different thrusts in each rotor sail 10, such a vessel 1 generates different moments at each position around the ship's center of gravity G, making the moment unbalanced for the entire hull 11. As a result, the vessel 1 can generate a turning moment TM using the plurality of rotor sails 10 without relying on mechanical means such as propellers or rudders, and thereby perform a turn. Therefore, the vessel 1 can change the direction of the hull 11 to a desired direction using only the plurality of rotor sails 10.
