Abstract

An anti-roll system for a water vessel is configured for stabilizing the water vessel from rolling about its longitudinal axis. The anti-roll system has a sensor configured for sensing information within a field of view of the sensor surrounding the vessel, and a controller operatively connected to the sensor. The controller is configured to receive the sensed information, determine whether the sensed information contains data indicative of a wave moving toward the vessel, and issue a turning instruction to a turning mechanism of the vessel when the wave is sensed. Execution of the turning instruction by the turning mechanism turns the vessel from a first position, where the longitudinal axis of the vessel is acute or obtuse relative to a major longitudinal axis of the wave, to a second position, where the longitudinal axis of the vessel is substantially perpendicular with the major longitudinal axis of the wave.
