ABSTRACT:
A motor boat hull is provided with a longitudinal channel formed in the central portion of the underside surface, starting at an intermediate location and terminating at the stern. Exhaust gases from the propulsion engine are introduced into the forward portion of the channel and the gases flow toward the stern thereby reducing the contact of the hull with the water and reducing the hull-to-water friction levels and reducing the power required to propel the hull at a given speed.
