Built by Cornish Crabbers between 1976 and 2001, this 19-foot centerboard dinghy represents a classic approach to traditional British small boat design. Roger Dongray created a vessel that bridges the gap between pure daysailer and pocket cruiser, with its standing lug rig delivering both simplicity and performance. The Coble's relatively deep draft of 3.51 feet provides excellent stability and windward ability, while the centerboard configuration allows for shallow water exploration and easy beaching. With 380 hulls produced over its 25-year production run, the design clearly found favor among sailors seeking a boat capable of both spirited sailing and gentle family outings. This GRP construction makes for a low-maintenance craft suited primarily to coastal waters and protected bays. The generous beam provides good initial stability, while the moderate displacement keeps the boat responsive in light airs. The standing lug rig is particularly appealing to traditional sailing enthusiasts, offering straightforward handling without the complexity of modern rigs. While not designed for offshore passages, the Cornish Coble excels as a coastal explorer and weekend sailor, combining seaworthy characteristics with the charm of traditional British small craft design.
