Abstract:
1. A waterjet propulsion system for a water-borne vessel, including: port and starboard waterjet propulsion units, thrust steering means associated with the port waterjet propulsion unit(s) and thrust steering means associated with the starboard waterjet propulsion unit(s) for deflecting the waterjets from the propulsion units for steering the vessel, which thrust steering means are linked for common steering movement together, thrust reverse means associated with the waterjet propulsion units for reverse deflecting the waterjets from the propulsion units and which thrust reverse means are mounted independently of the thrust steering means, first control means operable to actuate the thrust reverse means, and responsive within a first degree of freedom to actuate the thrust reverse means to cause common deflections of thrust for the port and starboard propulsion units and within a second degree of freedom to actuate the thrust reverse means to cause different deflections of thrust for the port and starboard propulsion units; and second control means operable to control the thrust steering means.
