Designed by André Herbulot in 1962, this French sailboat represents classic European design philosophy from the golden era of fiberglass boat development. Built by Constructions Mecaniques De Normandie, the As De Trefle showcases traditional construction methods with its plywood hull and single chine design, making it both affordable and seaworthy. At just over 20 feet, this compact cruiser offers surprising interior volume thanks to its generous beam of 7.22 feet. The fractional sloop rig with 224 square feet of sail area provides excellent sail handling characteristics, while the fin keel with transom-hung rudder delivers responsive steering and solid windward performance. With a displacement of 1,764 pounds and substantial ballast ratio, the boat maintains good stability despite its modest size. The comfort ratio of 10.4 indicates this is a relatively tender boat that prioritizes speed over ultimate seaworthiness, while the capsize screening formula of 2.39 suggests it's best suited for protected waters and coastal sailing rather than offshore passages. The SA/Displacement ratio of 24.6 reveals spirited performance in light to moderate conditions, making it an excellent choice for day sailing and weekend coastal cruising. This design appeals to sailors seeking classic aesthetics with modern sailing characteristics in a trailer-able package.
