Abstract

PURPOSE: To improve steering performance and course maintaining stability at slow speed, by providing a swingable rudder.
CONSTITUTION: A rudder 27 is protruded into water outside the region of a jet 26 from a water jet means 14 mounted on the central part of the stern of a hull 12. The rudder can be swung on a vertical plane by a horizontal pin and is coupled to a rudder shaft 22 through a tie rod 39. As a result, at slow speed the rudder 27 is swung into an underwater protruded functioning position by a tension spring 38 to eliminate the shortage of course maintaining stability due to insufficient momentum of the water jet 26. Since the rudder 27 is not affected by the jet 26, steering performance is improved. Under high speed, the rudder 27 is swung out of the water into a non-functioning position against the tension spring 38 to prevent an adverse effect due to the presence of the rudder.
