ABSTRACT:
Pitch of a vessel is controlled by trim tabs mounted on the stern of the vessel. The trim tabs are hinged along an axis transverse to the fore-aft direction of the vessel. A hydraulic system changes the plane of the trim tabs in response to a gyro-controlled servo system that senses changes in the fore-aft level of vessel. The trim tabs operate dynamically to maintain the fore-aft level substantially constant or within limits that effectively moderate the pitching motion of the vessel.
