The disclosed invention is a user-propelled device with no moving parts. The user places a single ski on each foot, the skis being independent from one-another. As the user strides the natural motion of his legs causes the skies to rise and fall with respect to the surface of the water. This rising and falling motion, and the resulting weight shift of the user, engages and disengages a plurality of paddles. Through this natural motion, the paddles are engaged when the foot is moving backward with respect to the user, and disengaged when moving forward with respect to the user. The result is forward motion with a natural gait, with automatic paddle engagement and disengagement.
