Frictional resistance to motion of a boat is reduced by generating an unconfined layer of intermixed air bubbles and water adjacent at least a portion of the hull of the boat including at upcurving side surfaces of the hull. In the preferred form of the invention, an array of spaced apart airflow apertures in the hull extends outward and upward at each side of the keel at a plurality of locations along the hull. Air is forced through the apertures by a compressor or a forward facing air scoop or by a combination of both. In the preferred embodiment, barnacle inhibiting fluid may be released through the array of apertures when the boat is docked or at anchor.
