Designed by renowned Danish naval architect Knud Olsen in 1957, this single-handed dinghy has earned its place as one of sailing's most respected development classes. With over 11,000 hulls built across six decades, the Ok Dinghy represents a perfect balance of performance, accessibility, and competitive sailing excellence. At 13.10 feet overall with a narrow 4.92-foot beam, this centerboard dinghy delivers exceptional responsiveness and speed while remaining manageable for sailors of varying skill levels. The unstayed cat rig keeps things beautifully simple, eliminating the complexity of standing rigging while providing 91 square feet of working sail area. This configuration makes the boat particularly appealing for both recreational sailing and serious competition. The Ok Dinghy's lightweight 159-pound displacement and plywood/fiberglass construction contribute to its lively performance characteristics, while the high sail area to displacement ratio of 49.64 ensures exciting sailing in moderate conditions. Originally conceived as an affordable alternative to more expensive racing dinghies, it has evolved into a sophisticated platform that rewards skilled helmsmanship. Today's Ok Dinghy sailor enjoys access to active fleets worldwide, making it ideal for club racing, regional championships, and international competition, including World Championships that attract sailing's elite athletes.
