ABSTRACT:
A jet propulsion system is provided for ships. Port and starboard ductways are provided with radial constrictor axial-flow impellers, and the output flow therefrom is divided between hull-bottom and hull-side discharge outlets. A stabilizer system is provided comprising pivotal deflectors in the hull-side jet outlets and means to automatically control these deflectors responsive to both rate of roll and angle of roll to counteract rolling of the vessel.
