The present invention is concerned with a boat hull. The boat hull includes a channel shaped bottom part having a keel and an undersurface having a plurality of corrugations which are located on each side of the keel thereby forming a plurality of alternating hills and valleys. Each valley has a vertex and each corrugation is V shaped in section thereby providing an oblique line and a substantially horizontal line characterized in that in section the successive lines of slope formed by adjacent oblique lines of the corrugations form a multiplicity of angles of deadrise which are all greater than the substantially constant angle of deadrise formed by joining a line through a row of vertices in section. |
