About the Fleet O Wing Sailboat

Designed by the legendary firm Sparkman & Stephens in 1939, this classic 17.75-foot sloop represents pre-war yacht design at its finest. With only 15 hulls built by Marcus C. Lowell & Son, the Fleet O Wing stands as a rare example of wooden boat craftsmanship from sailing's golden era. The yacht's proportions reveal a boat built for performance and seaworthiness. Her fractional sloop rig carries 149 square feet of sail on a relatively light 1,200-pound displacement, creating a spirited sailor capable of impressive speed for her size. The fin keel with rudder on skeg configuration was progressive for 1939, offering better maneuverability than full-keel contemporaries while maintaining directional stability. With a comfort ratio of 11.01, she's designed more for day sailing and short coastal passages rather than extended cruising. The low capsize screening value of 2.26 indicates excellent stability characteristics, making her well-suited for spirited sailing in moderate conditions. Her hull speed of 5.10 knots suggests she'll provide exciting sailing without being overwhelming for recreational sailors. Today, these rare Sparkman & Stephens designs are highly sought after by collectors who appreciate classic yacht design and impeccable construction heritage.
