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.
