Abstract: A water riding apparatus is provided for moving along the surface of water in cross-country skier type fashion. The water riding apparatus includes a first pontoon having an elongate hull and a second pontoon having an elongate hull. The first and second elongate hulls are connected together for relative parallel longitudinal motion by a gliding mechanism affixed to inner sides of the first and second elongate hollow hulls. The first and second elongate hulls include foot well openings allowing the user to stand on the bottoms of the hulls at a location below the water line of the hulls. The water riding apparatus further includes a personal stabilizer system for supporting a user in a standing position. The first and second elongate hulls can be locked in a parallel, transversely aligned relationship to allow alternative use of the water riding apparatus in a sitting, kayak-type fashion.
