About the Nautor 50 Sailboat

Built by the prestigious Finnish yard Nautor between 1976 and 1978, this rare Sparkman & Stephens design represents a brief but notable chapter in the builder's history beyond their famous Swan line. With only nine hulls completed during its short production run, the Nautor 50 stands as an exclusive alternative for discerning sailors seeking proven offshore capability. The design showcases classic S&S proportions with a moderate beam of 15.09 feet and substantial displacement of 50,926 pounds, creating the stable platform essential for serious bluewater cruising. The masthead ketch rig provides excellent sail handling options and weather flexibility, while the fin keel with rudder on skeg configuration delivers reliable directional control in challenging conditions. Her impressive comfort ratio of 51.51 reflects the generous interior volume and seakeeping abilities that make extended passages pleasant, while the conservative capsize screening formula of 1.63 confirms her ocean-going credentials. The robust fiberglass construction and Nautor's legendary build quality ensure structural integrity for demanding offshore work. This design appeals particularly to experienced sailors planning serious coastal and offshore cruising, offering the perfect blend of performance, comfort, and seaworthiness that defines the best of 1970s cruising yacht design philosophy.
