Abstract
A turning-aid nozzle mounted in the region of the outlet of a watercraft's propulsion system comprises a starboard inner surface and a port inner surface protruding radially inwardly from the nozzle in such a manner as to obstruct the flow of water from the watercraft's propulsion system. When turning to port, the starboard inner surface obstructs a portion of the water jet exiting the propulsion system, thereby producing an additional turning moment that aids the nozzle in turning to port. Similarly, when turning to starboard, the port inner surface obstructs a portion of the water jet exiting the propulsion system, thereby producing an additional turning moment that aids the nozzle in turning to starboard.
