1. A small watercraft rowing fin system, comprising: a. two rotating fin assemblies mounted on the opposite sidewalls of a watercraft, each said fin assembly including a rotating post disposed on over the outside surface of a sidewall of a watercraft, each said post including an upper end and a lower end, each said post being sufficient in length so that said upper end is located adjacent to the upper edge of the sidewall and said lower end extends into the water surface when the watercraft is placed therein; b. a means for mounting each said post vertically on the outside surface of the sidewall; c. a handle hinge securely mounted on the upper end of each said post; d. a rowing handle attached at one end to each said handle hinge, said rowing handle capable of being extended inward and grasped by the user when rowing, said handle able to swing in a vertical 180 arc over said handle hinge thereby allowing the rower to sit in a rearward facing or a forward facing direction and row; and, e. a perpendicularly aligned fin attached to said lower section of each said post, said fin being oriented on said post so that as said handle is extended inward and moved in an arc back and forth over the watercraft, the fins move in an arc back and forth in the water to produce continuous propelling forces in the water.
