Designed by Doug Peterson and built by Britton Yacht Corp./Tartan Marine starting in 1982, this 43-foot sailboat represents a compelling blend of cruising comfort and sailing performance. The Tangent One showcases Peterson's renowned ability to create boats that excel both as comfortable cruisers and capable performers, with design elements that reflect the era's emphasis on balanced sailing characteristics. The boat's fiberglass construction with balsa core sandwich provides an excellent strength-to-weight ratio, while the fin keel with spade rudder configuration delivers responsive handling and efficient sailing performance. With a displacement of 18,300 pounds and substantial ballast of 9,050 pounds, the Tangent One offers reassuring stability for offshore passages while maintaining the agility needed for spirited sailing. The masthead sloop rig carries 888 square feet of sail area, providing a sail-area-to-displacement ratio of 20.54 that strikes an ideal balance between performance and manageability. The low comfort ratio of 25.28 indicates a relatively quick motion that serious sailors will appreciate, while the capsize screening formula of 1.97 suggests good offshore capability. This combination makes the Tangent One well-suited for coastal cruising, club racing, and extended offshore passages where both comfort and performance matter.
