Abstract
Sport boat pedal, the class comprising a propulsion system operated by pedal and chain, characterized essentially by the fact that the body of the boat is a helmet similar to sports canoes, equipped at the stern with a wide opening where it houses a special propulsive wheel, constituted by a series of parallel circular corrugations corrugated in its plane and joined together by the points of tangency of the crests of the opposing waves, the extreme crowns being linked by a crosspiece to an axis passing through the center of all of them and fastens its ends in bearings arranged in the lateral parts of the stern opening, where it receives the command through the chain.
