Abstract
Abstract This aquatic recreational and exercise device is intended to be propelled over the surface of a body of water, and is partspherical in shape having open ends and being of such dimensions that a person can stand, walk or run within it. The body of the device is formed of an annular series of buoyant segments each having an external outwardly extending paddle, and the device is propelled along and over the water by the operator walking or running within it in the direction he wishes to go, while a modification would allow for powered operation. An annular buoyant member is attached at each open end of the part-spherical body to provide stability.
