ABSTRACT:
An aquatic sporting device, designed for use with one arm, is formed of three removably attached sections including a paddle blade, a forearm brace, and an elongate longitudinal shaft between the blade and brace. The brace is offset both longitudinally and transversely from a proximal end of the shaft, to permit placement of the brace against the forearm at the elbow, yet permit full bending of the arm at the elbow. A hand gripping area is provided along the shaft, and enables selective gripping along the shaft length to facilitate positioning of the elbow with respect to the brace for maximum paddling leverage, regardless of the size of the forearm. When removed from one another, the sections can be conveniently stored or transported. The removable mounting further permits substitution of other working implements, such as a fish net or gaff hook, in lieu of the paddle blade.
