A combined Kort nozzle and rudder steering system for vessels requiring a high degree of maneuverability. A Kort nozzle is mounted around the propeller to direct the wash to generate a first turning source, and a rudder is mounted behind the Kort nozzle to react with the wash exiting the nozzle to produce a second turning force. The nozzle and rudder are pivoted in the same directions simultaneously, but with the rudder being pivoted at a faster rate than the nozzle. The nozzle is pivoted to an optimal maximum angle relative to the wash generated by the propeller and the rudder is pivoted to an optimal maximum angle to the wash exiting the nozzle.
