In a 1994 review Richard Sherwood wrote, "the hulls are wide at the bottom and narrow at the top to create extra buoyancy ... In spite of the high aspect ratio, the center of effort is low." By 1994 there were racing fleets established in Australia, Europe, Japan and the United States. See also. Similar sailboats
