A hydrofoil apparatus for attachment to a marine vessel having a first pivot means for positioning the rotational axis of a gooseneck shaft parallel to the yaw axis of the hull and a trailing load support arm having a forward end coupled to the gooseneck. A planing surface sensor or planing foil rides on the water surface. The planing surface provides a hydrodynamic force to hold the planing surface sensor on surface as the vessel moves with forward velocity. An elongated body member is pivotally coupled to rotate on a first pitch axis with respect to said planing surface sensor. The elongated body member is pivotally coupled to the trailing load support at its aft end. A vertical fin is coupled to support the elongated body member. The fin maintains the planing surface sensor forward of said second pitch axis. A lifting foil raises the bow of said marine vessel by provide a lifting force via the fin.
