A hull behavior control system for controlling behavior of a hull of a marine vessel includes a memory and at least one controller coupled to the memory. The at least one controller is configured or programmed to control a steering that changes the traveling direction of the marine vessel, obtain a water surface shape around the marine vessel, estimate movement of a wave based on the water surface shape, and when it is determined that the hull rides the wave whose movement has been estimated, control the steering so as to reduce an influence of the wave on the hull.

Hull behavior control system and marine vessel

A hull behavior control system includes a memory and at least one controller coupled to the memory. The at least one controller is configured or programmed to control a propulsion force of the marine vessel using a propeller of the marine vessel, obtain a water surface shape around the marine vessel, estimate movement of a wave based on the water surface shape, and reduce the propulsion force by controlling the propeller when it is determined that an impact force equal to or greater than a threshold value will act on the hull after the hull travels over the wave whose movement has been estimated.
