ABSTRACT:
An aerodynamic wing apparatus for use with a boat to reduce drag on the hull of a boat by lifting the boat partially out of the water. The wing is movable fore and aft so that it may be positioned near the center of gravity of the boat as the center of gravity changes depending upon the loading of the boat. The wing has variable pitch to provide for a relatively constant amount of lift over a range of boat speeds.
