A water ski boat having separate air foils attached to the forward and aft portions of the boat arranged to exert more lift on the aft portion than on the forward portion of the boat. Specifically, a water ski boat is disclosed having an elongated air foil, pivotally attached to the forward portion of the boat and a stacked pair of elongated airfoils pivotally attached to the aft portion of the boat. The angle of attack of each of the three airfoils can be independently adjusted. In addition, the aft pair of stacked airfoils as an assembly can be raised, lowered, and adjusted with respect to its angle of attack. In a further embodiment, vertical stabilization fins are provided for the ends of the aft airfoils and the ends of the forward airfoils. All of the airfoils are removably attached to the water ski boat so that the boat can be readily configured with or without airfoils.
