Abstract: The wake behind a water vessel may be enhanced for wake boarding or water skiing by providing a fluid fillable chair in the rear of the water vessel to act as ballast so as to increase the wake of the water vessel. As the water vessel moves through the water, the towed individual experiences an increased wake, thereby improving enjoyment of the activity. In a preferred embodiment, the chair of the present invention includes a seat portion and a back portion and wherein the seat portion is adapted to be filled with a volume of water. The back may be filled with water or air. By filling at least the seat portion with water, the weight of the chair is increased such that when the chair is positioned in the rear portion of a boat, a relatively large wake may be created as the boat moves through a body of water.
