Abstract

A stabilization system for a marine vessel includes at least two inflatable bladders configured to be attached to the marine vessel, a gyroscopic sensor configured to sense an angular orientation of the marine vessel, and a controller configured for inflating and deflating the at least two inflatable bladders responsive to the angular orientation sensed by the gyroscopic sensor.

First claim

The invention claimed is:

1. A stabilization system for a marine vessel having a primary means of flotation, the stabilization system comprising:
at least two inflatable bladders configured to be attached to the marine vessel substantially at a surface of a water line such that the at least two inflatable bladders are disposed below or at least partially below the surface of the water line, the at least two inflatable bladders being separate and apart from the primary means of flotation;
a gyroscopic sensor configured to sense a non-zero angular orientation of the marine vessel; and
a controller for inflating and deflating the at least two inflatable bladders responsive to the angular orientation sensed by the gyroscopic sensor when the marine vessel is underway and when the marine vessel is at rest.

2. The stabilization system according to claim 1 , further comprising an air control valve for each of the at least two inflatable bladders, the controller configured to actuate the air control valve to inflate or deflate each of the at least two inflatable bladders.

3. The stabilization system according to claim 2 , wherein each said air control valve comprises a two-way valve.

4. The stabilization system according to claim 2 , further comprising an air tank and a compressor configured to supply compressed air to the air tank, the air tank connected to each of the air control valves.

5. The stabilization system according to claim 4 , wherein the controller is configured to actuate the compressor to maintain a predetermined air pressure in the air tank.

6. The stabilization system according to claim 1 , wherein each of said at least two inflatable bladders comprises a plurality of interconnected inflatable bladders.

7. The stabilization system according to claim 1 , further comprising a manually operable activation switch for activating and deactivating the stabilization system.

8. A method for stabilization of a marine vessel comprising:
providing a marine vessel having a hull defining a primary means of full flotation for the marine vessel in water and a stabilization system, separate and apart from the primary means of floatation, including at least one inflatable bladder on a first side of the hull and at least one inflatable bladder on a second side of the hull;
providing a gyroscopic unit for measuring a non-zero angular rolling motion of the hull about an axis, the gyroscopic unit communicating the measured angular rolling motion to a controller; and
inflating or deflating at least one of the inflatable bladder on the first side and the inflatable bladder on the second side based upon the measured angular rolling motion.

9. The method for stabilization of a marine vessel according to claim 8 , further comprising inflating the at least one inflatable bladder on the first side of the hull when the marine vessel rolls in a direction towards the first side.

10. The method for stabilization of a marine vessel according to claim 9 , further comprising inflating the at least one inflatable bladder on the second side of the hull when the marine vessel rolls in a direction toward the second side.

11. The method for stabilization of a marine vessel according to claim 8 , further comprising providing an air control valve for each inflatable bladder, the controller actuating a respective air control valve for inflating or deflating the respective inflatable bladder.

12. The method for stabilization of a marine vessel according to claim 8 , further comprising manually actuating an activation switch to activate or deactivate the stabilization system.
