About the Calkins 50 Sailboat

Designed by Wendell H. Calkins and first launched in 1960, this substantial 50-footer represents classic American cruising yacht design from the golden age of offshore sailing. Built with traditional strip-planked mahogany construction by American Marine in Hong Kong and Stoll Shipyards in the USA, the Calkins 50 showcases the quality craftsmanship that defined serious cruising boats of the era. With her generous 43-foot waterline and moderate displacement of 27,500 pounds, this masthead sloop delivers impressive performance for extended offshore passages. The fin keel with rudder-on-skeg configuration provides excellent directional stability while maintaining manageable handling characteristics. Her substantial 7,000-pound ballast ratio ensures solid sailing performance in challenging conditions, making her well-suited for serious coastal and offshore cruising. The boat's impressive sail area of 1,038 square feet gives her respectable performance in light to moderate winds, while her hull speed of nearly 9 knots makes for efficient passage-making. The conservative comfort ratio of 34.43 and favorable capsize screening value of 1.59 underscore her seaworthiness and motion characteristics that prioritize crew comfort during extended voyages. This design appeals to sailors seeking a traditional, well-built cruising yacht capable of handling serious offshore work.
