摘要： A small self-propelled watercraft having a main hull and an outrigger hull that is powered by a fin like oar arrangement. The main hull seats the rider and provides the substantial portion of the buoyancy for the watercraft. The fin like oar arrangement includes a blade type fin that is supported for pivotal movement at the end of the oar and the degree of pivotal movement can be adjusted from the handle end of the oar. In addition, the fin like blade is supported for movement between forward and reverse thrust positions and this movement is also controlled at the handle of the oar.
