• Rotation of the main impeller thus causes additional co-directional and approximately equal rotation of the fin rudder blade at the trailing edge of the main impeller relative to the main impeller, thereby increasing the lateral forces generated by the rudder and thus improving the maneuverability of seagoing vessels.
