Generally, a small ship is lightweight, but is a planing craft type that maneuvers at a speed of 20 knots or higher. The speed, the maneuvering performance, and the seakeeping performance are greatly influenced according to a tilt such as trim and water wave at the time of sailing.
Therefore, there is a need for additional equipment to control the tilt of roll and pitching according to trim and water wave in a state of high-speed sailing.
In addition, in the related art, trim and tilt change are controlled by using a trim tab or an interceptor at the stern. However, thus, the resistance is increased, the thrust performance is deteriorated, the maneuverability is lowered, and the responsiveness is decreased. Therefore, there is a difficulty in controlling dynamic behavior in a rapidly changing sea state.
Therefore, a method for solving such problems is required.
