Abstract

1407426 Boat hulls L D STOLK 12 Feb 1974 47389/72 Heading B7A In a boat hull a transverse step 21 on the underside thereof has an air vent 23 with port and starboard keels 24 extending from the step to the transom. As the boat moves forward air is drawn in through inlets 26 and passes out through vents 23 via an air tunnel 27 to lift the boat. Inlets 50, Fig. 8, may alternatively be located below the foredeck 14. Air also passes through opening 22 between the bilge V's 11 and the waterline 41. The hull planes in three points comprising the two bilge V's as shown at 36 and 37 and the rear portion 45a of the after centre keel 45.
