1. A hull behavior control system for controlling behavior of a hull of a marine vessel including a steering that changes a traveling direction of the marine vessel, the hull behavior control system comprising:
a memory; and
at least one controller coupled to the memory and configured or programmed to:
control the 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;
upon determining 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; and
upon determining that the hull rides a crest of the wave whose movement has been estimated, control the steering so that the hull avoids the crest of the wave.
