Abstract

The boat's hull may be divided into three sections. The first section is in the bow. The section through this part of the hull is a monohull section of conventional design. The second section is the central part of the hull. The section through this part is rectangular at the front but changes to twin hull of the rear. The final and third section is shaped as at section (9) in profile. This twin hulled craft retains the advantages of a monohull craft in the bow. Twin keels may be fitted, if the craft is to be a sailing boat.
