About the Coco Archambault Sailboat

Built by French manufacturer Archambault between 1985 and 2002, this 21-foot sailboat represents classic European design philosophy with its emphasis on performance and seaworthiness. The Coco Archambault combines a relatively narrow beam of 8.86 feet with a deep draft of 4.46 feet, creating a hull form that prioritizes sailing ability over interior volume. Designed by the respected Harlé-Mortain team, the boat features a fin keel with rudder mounted on a skeg configuration, providing excellent directional stability while maintaining good maneuverability. The fractional sloop rig delivers 365 square feet of sail area, giving the boat a healthy sail area to displacement ratio that promises spirited performance in moderate conditions. With a displacement of 2,535 pounds and 992 pounds of ballast, the design achieves a good balance between lightweight performance and stability. The low comfort ratio of 10.38 reflects the boat's performance-oriented nature rather than cruising accommodations, while the capsize screening formula of 2.6 indicates reasonable stability for coastal sailing. With 110 hulls produced over its 17-year production run, the Coco Archambault earned a solid reputation among sailors seeking an affordable, well-built boat suitable for day sailing, racing, and short coastal cruises.
