To provide a ship and sail structure that reduce costs and allow for easy installation of sails. [Solution] In the vessel 1, the soft sail 40 is installed using existing column members 30 located on the upper deck 19. That is, the soft sail 40 can be installed using the existing column members 30 on the vessel 1 without having to add large sails such as rotor sails or dedicated sail-supporting members such as masts to the vessel 1. Therefore, the cost required to install the sail can be significantly reduced. In addition, by effectively utilizing the existing column members 30, the soft sail 40 can be easily installed. As a result, the position and orientation of the soft sail 40 can be easily changed by effectively utilizing the existing column members 30. Thus, costs can be suppressed and sails can be easily installed.

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.

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.
