Abstract: A device for allowing a user to move across a body of water. This device comprises at least one ski wherein the ski contains a foot strap, sandal, or similar type device allowing the user to attach his or her feet to the ski. This ski contains a self-propelling element in the form of a fin, rotationally coupled to the ski or a frame having louvered blades rotationally coupled to the frame. As the user moves the ski forward, the fin folds up, or the blades open, allowing the ski to easily slide forward. AS the user moves the ski back, the fin rotates down, or the blades close, to catch the water and hold the ski in place allowing the user to propel himself across the water. This device may also contain a rudder, and a rudder control allowing the user to steer these skis in the water.
