Designed by George O'Brien Kennedy in 1946, this classic wooden dinghy represents traditional British small boat craftsmanship at its finest. Built by Nunn Brothers using traditional clinker construction, only 63 examples of this fractional sloop-rigged centerboard dinghy were ever produced, making it a relatively rare find today. At 14 feet overall with a 13-foot waterline, the Dragonfly One Design strikes an elegant balance between manageable size and sailing performance. The 225-pound displacement keeps her light and responsive, while the generous 125 square feet of sail area provides spirited performance in moderate conditions. Her 5-foot beam offers reasonable stability for crew comfort, and the 4.5-foot draft with centerboard configuration allows exploration of shallow waters while maintaining good upwind ability. The boat's comfort ratio of 3.06 and capsize screening formula of 3.29 indicate she's best suited for protected waters, day sailing, and club racing rather than extended coastal passages. Her SA/displacement ratio of 54.11 suggests lively performance in light to moderate winds. The clinker-built hull construction showcases the traditional boatbuilding methods that defined British small craft of the era, appealing to sailors who appreciate classic wooden boat character and the maintenance traditions that come with it.
