Waterfowl decoy motion system and method

摘要

A waterfowl decoy motion system comprises a self-propelled floating decoy tethered to a submerged line supported below the surface of a body of water by stakes driven into the water bottom. A thruster is attached to the bottom of the decoy such that the direction of propulsion is offset from a longitudinal axis extending along the length of the decoy by an angle of at least one degree. The tether is slidably attached to the submerged line, and a swivel located on the tether allows the decoy to rotate freely. The decoy is guided by the line as it moves across the surface of the water. When the tether reaches a stopper near each end of the line, the offset propulsion angle causes the decoy to turn in an arcing path, turn around, and travel in the opposite direction. The decoy repeats this process in a continuous loop.

主权项

1. A waterfowl decoy motion system, said system comprising:
a. a waterfowl decoy comprising a buoyant body, said decoy having a propulsion device attached to the decoy for moving the decoy along the surface of a body of water, said propulsion device configured such that the direction of propulsion is permanently offset in a horizontal direction from a longitudinal axis extending along the length of the body of the decoy by an angle of at least one degree; b. a length of flexible line having two ends, each end securely attached to a stationary structure such that the line is substantially taut, said line disposed below the surface of the water; and, c. a tether having two ends, the first end slidably attached to the line, the second end securely attached to the decoy, said tether comprising at least one swivel such that the decoy can freely rotate in any direction.
