Abstract
A small boat dynamic roll stabilizer. The stabilizer includes two or more pairs of spaced-apart flexible bellows or air bags to receive and support a boat hull during passenger loading and unloading. Dynamic pitch is limited or even stopped for the boat hull by maintaining each of the bellows, which each has a contact surface contacting a portion of the hull from below (within the water), at an internal pressure great enough to support dynamic loading of the boat hull while allowing the water to support the hull's static load. A pressure chamber is provided that has its interior volume linked via ducting or piping with the bellows, and a controller uses a feedback loop to operate an actuator to move a piston within the pressure chamber to maintain the pressure of the chamber and linked bellows as the loading of the boat hull dynamically varies during loading and unloading.
