Auxiliary rudder for an electric azimuthing propeller intended for fast ships and operating method for said auxiliary rudder

摘要

The propeller system (7) is mounted beneath the keel (1) of the boat and in one version can have push and pull propellers (3,4). The electrically powered rudder (6) is mounted to be clear of the flow turbulence. This is moved through a controlled angle by a worm gear coupling to the actuator motor. The rudder can be used on fast water jet boats.
