Built by Canadian manufacturer Tanzer Industries starting in 1984, this 31-footer represents the company's commitment to producing affordable, well-built cruising sailboats. Designed by George Cuthbertson of the renowned Cuthbertson & Cassian firm, the Tanzer 31 combines proven hull geometry with practical accommodations for coastal cruising and club racing. The moderate fin keel and spade rudder configuration delivers predictable handling characteristics, while the masthead sloop rig provides versatility across various wind conditions. With a displacement of 8,300 pounds and 3,300 pounds of ballast, this boat strikes a reasonable balance between stability and performance. The comfort ratio of 20.98 indicates a relatively stiff ride suitable for experienced sailors, while the capsize screening formula of 2.08 suggests good stability for coastal waters. The Tanzer 31's fiberglass construction and thoughtful design details reflect the builder's focus on durability and value. Its 468 square feet of sail area and hull speed of 6.70 knots make it capable of spirited sailing, whether participating in weekend club races or exploring protected coastal waters. The compact 13-horsepower auxiliary engine provides adequate power for maneuvering in tight quarters and calm conditions.
