Abstract
A surface vessel has a hull that is configured to provide a mounting location for a waterjet pump propulsion system that is fully submerged under substantially all operating conditions of the vessel. A waterjet propulsion pump is mounted in an opening in the mounting location of the hull. At least the aft portion of the pump exit nozzle extends aft of the mounting location. A rotatable steering nozzle is coupled to the lower end of a rotatable steering shaft. A rotatable reversing deflector is coupled to the lower end of a rotatable reversing shaft that is either concentric with or parallel to the steering shaft. The steering shaft and reversing shaft extend upwardly through a shared opening or a pair of openings in the hull. Steering and reversing actuators associated with the steering and reversing shafts are located within the hull. A pair of steering deflectors in a 'clamshell' relationship is an alternative.
