ABSTRACT:
The present invention provides an apparatus for propelling a small boat through a body of water by use of a sculling action. The apparatus may be comprised of a vertical stock attached to a vertical surface of the boat, normally the transom. A wide, flexible fin may project outwardly and rearwardly from the bottom end of the vertical stock. A tiller may extend from the top end of the vertical stock towards the bow of the boat. The pumping action on the tiller causes the fin to move back and forth in a sculling action so as to propel the boat through the water. The apparatus may be easily folded into a compact package for storage in the boat either for emergency use or for storage of the boat. The fin may be bifurcated into a plurality of panels for more compact and efficient storage. Plates provided to hold the fin in a vertical orientation may have flanges along their upper edges to provide a step for easy reentry of a swimmer into the boat.
