A pair of buoyant skis are used by a person over a body of water for forward motion thereover by reciprocating motion of the skis in alternate fashion. Each ski is a mirror image of the other and includes an elongated, box-like hull, inwardly lined with buoyant material and defining a water-tight body which is generally right-triangular in cross-section and defines a top deck, a port wall transverse to the top deck and an upwardly inclined starboard wall joining the bottom edge of the port wall with the starboard edge of the top deck. A foot well is formed within the hull body intermediate the bow and stern. The two walls of the hull progressively converge from the stern to the bow. The port wall is straight throughout its length while the starboard wall is longitudinally straight except for a curved bow section which joins both walls. The bottom edge of the port wall forms a longitudinally extending straight keel and additional longitudinal keels protrude from the starboard wall. The two skis do not spread apart during forward motion and produce minimum drag.
