  • Patent number: 7347759
    Abstract: A self-propelled aquatic apparatus having a duck shaped body, wherein the body is partially filled with floatation material, a base, a waterproof battery container, a battery, a battery compartment, an electro-mechanical propulsion mechanism having a pair of webbed feet, which alternately articulate from a forward down position to a rearward raised position, and a power switch. The webbed feet are slightly cupped to enhance paddling efficiency when moving from the forward down position to the rearward raised position, and are made of a relatively flexible material, such that the webbed feet will distort rather than break if they encounter a hard surface or are bent, and will not scratch the skin.
