A motion control system for a ship has one or more sensors generating sea condition data and at least one ship control system. Analyzer software receives the sea condition data and predicts a sea condition event. Calculator software calculates one or more commands in preparation for the sea condition event. Interface software communicates the one or more commands to the at least one ship control system and the at least one ship control system implements a command in advance of the event. The at least one ship control system may comprise a ride control system having one or more motion control devices. The at least one ship control system may also comprise an auto pilot system.

1. A motion control system for a seafaring vessel, comprising: one or more sensors generating current sea condition data;a storage having historical sea condition data stored thereon;at least one control system; anda computer having: an analyzer receiving the current sea condition data and the historical sea condition data and determining a not yet existing predicted sea condition anticipated to be encountered by the vessel in the future based at least in part on both the current sea condition data and the historical sea condition data;a calculator calculating one or more commands in preparation for the predicted sea condition determined by the analyzer; andan interface communicating the one or more commands calculated by the calculator to the at least one control system;wherein the at least one control system automatically implements at least one of the one or more commands calculated by the calculator in response to the predicted sea condition determined by the analyzer;wherein the one or more sensors are configured to measure sea conditions in the seafaring vessel's near and far fields when the vessel is underway to characterize sea conditions such that the sea condition data relates to sea conditions in both the seafaring vessel's far field and near field, the far field being defined as four or more wavelengths from the vessel;the near field being between the vessel and the far field;wherein the not yet existing predicted sea condition is in the far field. 2. The system of claim 1, wherein the at least one control system comprises a motion control system having one or more motion control devices; and the one or more commands comprises activating the one or more motion control devices. 3. The system of claim 2, wherein the one or more motion control devices comprises at least one of the following: fin, foil, interceptor, trim tab, T-foil, lifting foil, rotor, rudder, steerable water jet, internal stabilizer, movable weight, anti-roll tank, gyroscope. 4. The system of claim 1, wherein at least one of the one or more sensors is on the ship. 5. The system of claim 1, wherein the predicted sea condition comprises at least one of the following: wind, waves, current. 6. The system of claim 1, wherein the far field comprises a distance of 1 kilometer from the seafaring vessel. 7. The system of claim 1, wherein the seafaring vessel's near field is over an area adjacent to the seafaring vessel that is less than 10 times the wave length. 8. The system of claim 1, wherein the one or more commands comprises configurations for one or more of the seafaring vessel's mechanical systems in preparation for the predicted sea condition. 9. The system of claim 1, wherein the one or more commands comprises configurations for one or more of the seafaring vessel's hydraulic systems in preparation for the predicted sea condition. 10. The system of claim 1, wherein the one or more commands comprises configurations for one or more of the seafaring vessel's electrical systems in preparation for the predicted sea condition. 11. The system of claim 1 wherein the at least one control system comprises an auto pilot system. 12. The system of claim 1 wherein the one or more sensors comprises a motion sensor pack. 13. The system of claim 1 wherein the one or more sensors measures sea conditions in the seafaring vessel's encounter quadrant. 14. The system of claim 1 further comprising a storage having vessel data concerning a vessel's behavior in the predicted sea condition, wherein the one or more commands are based at least in part on the vessel data. 15. The system of claim 14, wherein the vessel data comprises historical vessel motion data. 16. The system of claim 1 wherein the historical sea condition data comprises sea condition data generated by the one or more sensors in the past. 17. The system of claim 1, wherein the slope and extent of an encounter wave is used as a predictor of vessel motion. 18. The system of claim 1 wherein the at least one of the one or more commands includes a course correction based on the sea condition data related to the far field. 19. A method for controlling stabilization of a seafaring vessel which is underway, comprising the steps of: providing a control system;detecting current sea conditions using one or more sensors which are configured to measure sea conditions in both the far field and near field, the far field being defined as one kilometer or more from the vessel, and, the near field being between the vessel and the far field;retrieving historical sea condition data from a storage;determining a not yet existing predicted sea condition anticipated to be encountered by the vessel in the future in the far field, on a computer, using both the detected current sea conditions and the historical sea condition data;calculating one or more commands, on a computer, using the predicted sea condition; andsending the one or more commands to the control system;wherein the control system automatically implements at least one of the one or more commands in anticipation of the predicted sea condition, the one or more commands including a new heading for the seafaring vessel. 20. The method of claim 19, further comprising the step of providing a storage having historical vessel motion data and historical sea condition data, wherein the one or more commands are based at least in part on the historical vessel data and the historical sea condition data. 21. The system of claim 19 wherein the near field is between the vessel and one kilometer. 22. A motion control system for a seafaring vessel which is underway, comprising: a plurality of sensors generating current sea condition data, the sea condition data including sea conditions in both the seafaring vessel's far field and near field;a storage having historical sea condition data stored thereon;a motion control system having one or more motion control devices; anda computer having: an analyzer receiving the current sea condition data and the historical sea condition data and determining a not yet existing predicted sea condition anticipated to be encountered by the vessel in the future in the far field based at least in part on both the current sea condition data and the historical sea condition data, wherein the near field represents an area between a minimum and a maximum, the minimum being a sufficient lead time to implement a new heading in response to a predicted encounter and the maximum being at least two wavelengths from the minimum;the far field being beyond the maximum;a calculator calculating one or more commands in preparation for the predicted sea condition determined by the analyzer; andan interface communicating at least one of the one or more commands calculated by the calculator to the motion control system;wherein the motion control system automatically activates the one or more motion control devices in response to the predicted sea condition using the at least one of the one or more commands calculated by the calculator. 23.
