Designed by Guy Thompson and first launched in 1971, this British-built 27-footer represents classic early-1970s sailing design philosophy with its traditional fin keel configuration and masthead sloop rig. The fiberglass construction delivers durability while maintaining the refined lines characteristic of Thompson's work during this era. With a displacement of 6,100 pounds and substantial ballast of 2,767 pounds, this boat offers reassuring stability for coastal cruising and weekend adventures. The generous beam of 8 feet provides comfortable interior space despite the compact 26.67-foot overall length, while the moderate 5.67-foot draft allows access to a variety of harbors and anchorages. The Thompson 27's comfort ratio of 25.62 indicates a relatively stiff, performance-oriented design that favors sailing efficiency over pure comfort, making it well-suited for sailors who enjoy spirited sailing in moderate conditions. The capsize screening formula of 1.75 suggests good stability characteristics for coastal and near-shore sailing, though extended offshore passages would require careful weather planning. Built during an era when British boatbuilding was renowned for solid construction and practical design, the Thompson 27 appeals to sailors seeking a manageable boat that doesn't sacrifice sailing performance for size.
