SHIP MANEUVERING DEVICE AND SHIP

This ship maneuvering device causes a ship having at least one propulsion device mounted thereon to travel along a scheduled course. The ship maneuvering device is provided with a control unit. The control unit acquires an azimuth deviation between an actual bow azimuth, which is the current bow azimuth of the ship, and a target bow azimuth of the ship, and, on the basis of the azimuth deviation, generates a thrust command that indicates the thrust with which the ship is to be propelled. In the case where the azimuth deviation is equal to or greater than a prescribed value, the control unit generates a thrust command such that causes the speed of the ship is reduced below an actual speed which is the current speed of the ship.
