Abstract

A variable geometry fin for use in a ship stabilization system is provided. A stabilization element adapted to extend below the water line of a ship. The stabilization element has a foil body and a trailing edge assembly extending from inside of the foil body. The trailing edge assembly includes an extension body having two opposing surfaces, a trailing edge attached to an end of the extension body, a vortex generator having protrusions and/or recesses on the two opposing surfaces, and at least one support guide located on an outboard side of the extension body. A deploy mechanism is attached to the foil body and the trailing edge assembly. The trailing edge assembly extends rearwardly from the foil body producing an additional surface area.
