Its underwater shape is similar to that of the Eagle . Paddlers weighing less than 180 pounds do not fully submerge the ends of the boat, making it turn too quickly for good control in adverse wind conditions. The Merlin II has a straighter keel and the gunwales are more similar to the Streuer Delta . To achieve better tracking characteristics, the Merlin II has slightly more drag than the Merlin , but it handles more easily, particularly for lighter paddlers. All Van Dusen racing boats are constructed using advanced-technology composite materials and sophisticated manufacturing processes.
Most hull designs are available in several hull laminates.
Competition kayaks and canoes are manufactured without material or technical compromise. The hull laminate includes Nomex honeycomb, carbon fiber, and fiberglass cloth pre-impregnated with epoxy resin. The hulls are heat-cured under pressure. Competition kayaks and canoes achieve the minimum weight for international competition or fall slightly below the minimum. Competition kayaks and canoes are light blue.
