Abstract
A hydro-ski craft in which load alleviation is attained by reducing the effective wetted area of the planing surfaces at high speeds, and in which elongated flaps extending longitudinally of the craft are mounted to swing about longitudinal axes between generally horizontal planing positions and upwardly swung retracted positions. Spray control dams may be carried by the flaps to themselves automatically swing between inactive and active positions in response to upward swinging movement of the flaps.
