<p>Vessel having a non-planing hull provided with an attached foil which is below the surface of the water and spaced from the hull. The foil is attached in 5 proximity to the aft end of the vessel, and is oriented with a downward tilt of between greater than zero degrees and less than or equal to about 22° relative to the horizontal, to provide a lifting force with a force component in the forward direction. The foil can be located entirely behind the vessel, or partly below the aft hull portion of the vessel with no more than about half the foil being forward 10 of the location where the hull leaves the water. In the latter case, the hull is preferably provided with a recess.</p> |
