ABSTRACT:
A rudder assembly which includes a frame formed by upper and lower horizontal flanges which are connected to a rudder post. A pair of parallel vertical sidewalls are connected to the upper and lower flanges, and a main rudder blade is connected to the upper and lower flanges between, and parallel to, the sidewalls. A forward blade is pivotally connected to the frame at a location forward of the main blade for movement about a vertical axis between a non-turning position where the forward blade is generally aligned with the main blade, and a turning position where the rear edge of the forward blade engages one of the sidewalls to form a channel for feeding water along the backside of the main blade to improve rudder turning efficiency.
