The cat is stiff but also relatively light, thanks in part to vacuum-bagged and balsa-cored construction, giving it a light-ship displacement of 19,790 pounds. Combined with an easily managed total working sail area of 990 square feet (1,625 square feet downwind), the boat performed well. During our test sail off Annapolis in just 6 to 8 knots of wind, we recorded 5.5 knots sailing upwind and 6.5 knots while reaching. And boat speeds will certainly increase in more breeze. Twin fixed keels and spade rudders allow owners to sail in water that's 4 feet deep or to nose the cat up on a beach, but they still allow superb maneuverability, upwind performance, and speed under sail. Under power, the twin Yanmar 21-horsepower engines produced over 7 knots at a cruising rpm of 2,700 and 8 knots at 3,600 rpm.
