Disclosed is a human powered water walker having a plurality of two-position flippers for effecting propulsion and steering of the water walker when the same is is actuated by human power. Each of the flippers is beveled at its front end and has at its rear end a downwardly beveled tab. The water walker may have two interlaced boyant ski trimarans to which the flippers are connected.

A water walking apparatus having two inflatable pontoons, each with respective holes in their top surfaces for a footwell. A platform support may expand and contract when in use so as to accommodate variable spacing between the pontoons. The platform support may include curved saddle, which straddles over the curved outer surface of a pontoon, securing the platform support to the pontoons. A platform upon which a user may sit may be connected to the platform support by a neck received into a hole in the bottom of the platform. The platform may include a backrest member, and a strap that may serve as a ladder step when the backrest member is rotated rearwardly and down, into the water to allow a user to step on the continuous strap and climb up onto the platform.

This invention provides a foot-propelled catamaran watercraft having a pair of parallel, spaced-apart pontoons rigidly coupled together, an overhead support structure, coupled to the pontoons, from which a rider, wearing a harness, is suspendable, a rider stabilization structure consisting of a pair of mirror-image-operable tillers graspable by the rider, and a rudder mounted at the rear of each of the pontoons coupled to the tillers for steering the watercraft. The watercraft is propelled by rearward thrusting movements of the rider's feet, which are preferably equipped with fins, or flippers.
