Abstract
Depressors mounted on the stern of a marine vessel are deployed by displacement from positions retracted from the seawater to positions immersed therein so as to divert exit flow of the seawater along retarded flow paths from the stern during vessel travel. Such deployment of the depressors is regulated under motion stabilizing control to produce corrective roll and pitch inducing forces on the vessel in response to diversions of the exit flow by the depressors.
