ABSTRACT:
A stabilizer system is used to stabilize a marine vessel hull. The system includes at least one stabilizer assembly attached to the hull and the stabilizer assembly is capable of moving with respect to the hull in response to ambient sea surface conditions detected by the system. Each stabilizer assembly includes an outrigger arm and a float arm which has a float attached to one end. The float arm can expand and contract in order to keep the float in contact with the sea surface or lift it from contact. Additionally, the float can have the ability to change its cross-sectional shape and volume with respect to the waves. The entire stabilizer assembly, and various components thereof, have the ability to position themselves in response to commands generated by the system. The system predicts impending adverse motions, such as oncoming waves, in order to position the stabilizer assemblies and the vessel in optimum positions so as to negate the effect of the oncoming wave on the vessel.
