A paddle device. First and second paddle assemblies each have a paddle blade extending from a paddle end of a paddle arm so that the paddle structures each have a paddle blade end and a paddle arm end. A hand crankable crank shaft arrangement have a center and first and second ends and having handle segments. The paddle arm end of the first paddle structure is coupled to the first end of the crank shaft arrangement and the paddle arm end of the second paddle structure is coupled to the second end of the crank shaft arrangement. First and second handle grips are rotatably coupled to the crank shaft arrangement so as to permit the crank shaft arrangement to rotate with respect to the first and second handle grips when the crankshaft arrangement is cranked. This abstract is not to be considered limiting.
