Colvic Craft 31

Launched in 1972, this masthead ketch from John Bennet & Associates represents classic British yacht design philosophy of the early 1970s. Built by Colvic Craft and later Ardleigh Laminated Plastics, the design emphasizes seaworthiness and comfort over racing performance, making it well-suited for coastal cruising and offshore passages. The long keel configuration provides excellent directional stability and comfortable motion in seaways, though at the expense of maneuverability in tight quarters. With a displacement of 15,695 pounds and moderate sail area, this yacht prioritizes steady progress over speed, achieving a hull speed of 7.09 knots. The ketch rig offers versatility in sail handling and balance, particularly valuable for shorthanded sailing or heavy weather conditions. The comfort ratio of 39.04 indicates a motion that favors relaxed cruising over athletic sailing, while the capsize screening formula of 1.6 suggests good stability characteristics for offshore work. The SA/Displacement ratio of 7.53 confirms this is a cruising design rather than a performance-oriented yacht. This combination of characteristics makes the Colvic Craft 31 appealing to sailors seeking a traditional, seaworthy platform for extended coastal cruising or ocean voyaging.
