Northern 29
Description
The Northern 29 is a classic 29-foot fiberglass monohull sailboat designed by the renowned firm Sparkman & Stephens (design #2047) and built by Northern Yachts Ltd. in Goderich, Ontario, Canada, starting in 1972 as an IOR Half Ton racer-cruiser optimized for performance and seaworthiness. Featuring a fin keel with skeg-hung rudder, keel-stepped aluminum mast, and fractional sloop rig with 388 square feet of sail area, it boasts a displacement of 7,250 pounds (including 3,750 pounds of lead ballast for a high 51.7% ballast ratio), a moderate displacement-length ratio of 294 classifying it as a medium-weight cruiser, and a sail area/displacement ratio of 16.5 indicating reasonably good speed potential without being underpowered. A total of 150 Northern 29 sailboats were built. Production began in 1970 (with the first examples completed as prototypes) and continued until 1987, when the hull mold was retired and the model was discontinued.
