SHIP MANEUVERING DEVICE AND SHIP

This ship maneuvering device (31) causes a ship (1) having at least one propulsion device (21a-21c) mounted thereon to travel along a scheduled course. The ship maneuvering device (31) is provided with a control unit (42). The control unit (42) acquires an azimuth deviation between an actual bow azimuth, which is the current bow azimuth of the ship (1), and a target bow azimuth of the ship (1), and, on the basis of the azimuth deviation, generates a thrust command that indicates the thrust with which the ship (1) is to be propelled. In the case where the azimuth deviation is equal to or greater than a prescribed value, the control unit (42) generates a thrust command such that causes the speed of the ship (1) is reduced below an actual speed which is the current speed of the ship (1).
