Abstract

The float has a rounded bow curved in the horizontal and vertical planes. The deck has a wide portion behind the bow and a reducing width towards the stern. The hull has an increasing depth to about a third of its length, and has a hydrodynamic shape with a shallow section towards the stem of the float. The section of the hull is elliptical around the bow when measured in the vertical plane across the hull.
