Abstract
A skidplate projecting into a body of water from a marine craft hull has a symmetric wedge formation extending from the leading edge to differently profiled surfaces on opposite sides of the skidplate producing lift and side force during travel. No side force is however produced during straight line travel by virtue of ventilated cavity enclosure of the profiled surfaces on both sides between cavity establishing streamlines extending through the water from the symmetric wedge formation.
