1. A ship maneuvering device for moving a ship equipped with at least one propulsion device along a scheduled course, the ship maneuvering device comprising:
a control unit configured to acquire an azimuth deviation between an actual bow azimuth which is a current bow azimuth of the ship and a target bow azimuth of the ship to generate a thrust command indicating thrust for propelling the ship based on the azimuth deviation, and
wherein, in a case where the azimuth deviation is greater than or equal to a predetermined value, the control unit is configured to generate the thrust command such that a speed of the ship decreases from an actual speed which is a current speed of the ship.
