Abstract

Boat hull or attachment with a plurality of longitudinally movable elements. Presently preferred embodiments utilize wings or ski members which are movable and maintainable between multiple positions to adjust the operational characteristics of the boat. The wings extend from the transom longitudinally along the aft half of the boat and include upwardly curved foil shaped front edges to provide lift. The ski members will generally extend along a substantial extent of the length of the boat. Bottom running surfaces of the respective ski members may be varied in angular disposition to operatively simulate a plurality of hull configurations.
