Abstract
A propulsion device for providing forward movement of a sailboat in the absence of wind takes the form of a flexible fin that is removably attached to a sailboat rudder. The fin member is connected to a strut configuration that extends over the tiller and the rudder, with the fin itself extending horizontally from the submerged end termination of the rudder. The fin is made of a flexible material that produces a good forward thrust when the tiller is moved back and forth, thus moving the sailboat forward at a sufficient speed.
Claims10
A propulsion device for use with a sailboat, the propulsion device comprising
- a strut configuration for releasably attaching along an outer edge of a rudder and tiller combination;
- and
- a flexible fin connected to a lower portion of the strut configuration in the vicinity of a lower portion of a rudder such that as the tiller is moved, the flexible fin provides forward thrust.
