Achilles 840

Designed by Chris Butler and built by Butler Achilles Ltd in the UK starting in 1979, this 27.75-foot sailboat represents solid British craftsmanship from an era when builders focused on seaworthiness over speed. The Achilles 840 features a moderate fin keel with rudder on skeg configuration that provides good directional stability and balanced helm characteristics. With a displacement of 5,500 pounds and ballast ratio of 45.5%, this masthead sloop offers reassuring stability for coastal cruising and short offshore passages. The comfort ratio of 18 indicates a relatively stiff, quick motion that experienced sailors will appreciate, while the capsize screening value of 2.04 suggests reasonable stability for offshore work, though prudent seamanship remains essential. The fiberglass hull with balsa-cored deck construction provides good strength-to-weight ratio and insulation properties. Her sail area to displacement ratio of 18.23 delivers respectable performance in moderate conditions, while the hull speed of 6.6 knots sets realistic expectations for passage planning. Best suited for coastal cruising, club racing, and occasional offshore adventures, the Achilles 840 appeals to sailors seeking a well-built, traditionally-proportioned yacht that prioritizes seaworthiness over outright speed. The modest 9.5 horsepower auxiliary engine provides reliable backup power for harbor maneuvering and calm weather motoring.
