PROBLEM TO BE SOLVED: To provide a navigation control method and a navigation control system of a ship capable of reducing hull vibration generated between an ocean current and an azimuth thruster when a hull turns.SOLUTION: When a ship provided on a stern part with at least a pair of right-and-left azimuth thrusters 2 capable of rotating a propulsion direction by a propeller along a horizontal direction is turned at a desired turning angle, the pair of right-and-left azimuth thrusters are rotated at a desired angle with respect to the propulsion direction, and each vibration generated in the pair of right-and-left azimuth thrusters is monitored individually, and the rotation angle of an azimuth thruster whose vibration becomes a prescribed level or higher is returned until the vibration is lowered to a prescribed level or lower, and if the turning angle of the hull becomes insufficient by the angle return, a driving force of the azimuth thruster on the angle return side is enhanced. |
