About the Tartan 31 Sailboat

Designed by Tim Jackett and built by Tartan Marine from 1987 to 1991, this 31-footer represents the builder's commitment to quality construction and thoughtful design during the late 1980s production boom. With 146 hulls completed during its four-year run, the Tartan 31 found a solid following among sailors seeking a well-built coastal cruiser with respectable performance characteristics. The boat's moderate displacement of 9,030 pounds and healthy ballast-to-displacement ratio provide good stability, while the fin keel and spade rudder configuration delivers responsive handling under sail. Her masthead sloop rig carries 506 square feet of sail area, offering a balanced sail-area-to-displacement ratio that suggests decent light-air performance without being overpowered in fresh conditions. Built with fiberglass construction to Tartan's typically high standards, the design emphasizes comfortable coastal cruising rather than out-and-out racing performance. The boat's dimensions create a practical interior layout within the 31-foot overall length, while maintaining seaworthy proportions. Her moderate draft of six feet allows access to most harbors while providing sufficient underwater profile for good windward ability. This combination of attributes makes the Tartan 31 well-suited for weekend cruising, coastal exploration, and club racing activities.
