A decoy with a counterweight suspended from a central keel attached along the centerline of the decoy behind the decoys center-of-gravity. When a wave swells beneath the decoy creating a force which would tend to cause a side-to-side rocking motion of the decoy, the counterweight absorbs a portion of the sway-inducing force, resisting the tendency of the decoy to rock. This provides a more natural bobbing of the decoy producing a believable rise and fall of the decoys head and body portion.
