ABSTRACT:
An apparatus attachable to the legs of a swimmer and structured to aid the swimmer by facilitating the generation of increased thrust as the swimmer moves through the swimming stroke, wherein the apparatus includes a primary foil movable relative to the swimmer's leg and automatically positionable at a predetermined, substantively optimum angle of incidence relative to the direction of relative water flow to the apparatus during movement of the swimmer. An attitude control assembly is maintained in alignment with the direction of relative water flow and is cooperatively structured with the primary foil so as to maintain the primary foil in the predetermined, optimum angle of incidence which facilitates the generation of maximum thrust during the entire swimming stroke.
