Abstract: An open cage for occupancy by a person, for recreational water activities. The person walks, runs, or otherwise maneuvers while inside, thus rotating the cage and propelling the same across the water. The open frame has floats attached to the exterior, the floats comprising toroidal, inflatable members, such as rubber, pneumatic inner tubes. Paddles comprising a cruciform arrangement of rigid sheets are attached to the open frame and project from inside each toroidal float. The paddles enhance engagement of the water, and the cruciform configuration enables the paddle to be effective regardless of the angle of travel across the water surface. The floats are strapped around cage frame members, there being an interior plate which anchors the straps and which clips to cage frame members. A friction tread disposed upon each plate affords a foot hold to a user. The cage frame assembles in peg and socket fashion.
