Abstract

1,273,692. Boat hull. K. W. ENGLISH and J. R. FILMER. 18 Jan., 1971 [16 Jan., 1970], No. 2291/70. Headings B7A and B7S. A boat hull for e.g. a small planing craft comprises two keels 3, 4 at the forward section and a single keel 6 at the rear. Keels 3, 4 may be lowerable and raisable while keel 6 may have a drop centre-board. Wheels may be provided on the hull so that the hull may travel on land.
