Description

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a display device and a ship. Description of Related Art In recent years, a ship that generates thrust using renewable energy such as wind power is known in order to reduce GHG such as CO2. For example, a ship disclosed in Japanese Unexamined Patent Publication No. 2020-45018 is provided with, on a hull, a wind propulsion unit that propels the hull using wind power in addition to a propeller-based propulsion device. SUMMARY OF THE INVENTION Here, in the ship as described above, an operation status of the hull such as a status of the wind propulsion unit is changed as appropriate in accordance with an environment such as a wind direction or a wind speed. Even though an experienced crew member can identify the operation status of the ship, there is an issue in that some crew members have difficulty in identifying the operation status. From the above, it is required to easily identify the status on board the ship. The present invention has been made to solve such an issue, and an object of the present invention is to provide a display device capable of easily identifying a status on board a ship, and a ship. A display device according to an aspect of the present invention displays information related to a ship provided with a wind propulsion unit on a hull, and the display device visualizes an operation status of the hull relative to environmental information. The display device according to the aspect of the present invention visualizes the operation status of the hull relative to the environmental information. In a case where an environment such as a wind direction or a wind speed with respect to the ship changes and an operation of each of devices including a wind propulsion unit is adjusted accordingly, the display device can visualize the operation status of the hull accordingly. Therefore, a crew member can easily identify the operation status of the hull by viewing the information visualized on the display device. From the above, the status on board the ship can be easily identified. The display device may visualize a moment acting on the hull based on a force generated by the wind propulsion unit. In this case, the crew member can easily identify what kinds of force and moment are acting on the hull by each wind propulsion unit, through visual information. The display device may visualize a status of a force generated by the wind propulsion unit. In this case, the crew member can easily identify what kind of force is generated in each wind propulsion unit. The display device may visualize a relationship between a ship speed of the ship and a required output, and visualize a status of involvement of an output of the wind propulsion unit in the required output. In this manner, the crew member can easily identify how much the wind propulsion unit contributes to the operation of the ship. The display device may visualize a charge level of a battery. Accordingly, the crew member can easily identify the charge level of the battery, and thus the charging and discharging of the battery can be performed at an appropriate timing. The ship may include, as navigation modes of the ship, at least: an engine-driven mode in which the ship is propelled only by a propulsion device; an engine-sailing mode in which the ship is propelled by both the propulsion device and the wind propulsion unit; and a sailing mode in which the ship is propelled only by the wind propulsion unit, and the display device may visualize the navigation mode that is being set. In this case, the crew member can easily identify which navigation mode the ship is currently operating in, among the plurality of navigation modes. The display device may visualize power balance in the ship. Accordingly, the crew member can easily identify the power balance in the ship. The display device may visualize a fuel economy effect achieved by the wind propulsion unit. In this manner, the crew member can easily identify the fuel economy effect achieved by the wind propulsion unit, and thus the environmental awareness of the crew member can be enhanced. The display device may share visualization information with land. Accordingly, a worker on land can easily identify the status on board the ship.
