About the Ericson 39 B Sailboat

Designed by renowned naval architect Bruce King and built by Ericson Yachts between 1975 and 1978, this 39-footer represents a classic example of mid-1970s American cruising yacht design. With only 20 hulls produced during its brief production run, the Ericson 39 B has become a relatively rare find in today's used boat market. King's design philosophy shines through in the boat's balanced proportions and seaworthy characteristics. The fin keel with rudder on skeg configuration provides excellent directional stability while maintaining good maneuverability under power. Her cutter rig offers versatility in sail handling, particularly valuable for shorthanded sailing or when facing challenging weather conditions. Built with solid fiberglass construction typical of the era, these boats were engineered for durability rather than lightweight performance. The substantial displacement of 19,000 pounds, with 50% ballast ratio, creates a stable, comfortable platform ideal for coastal cruising and capable of handling offshore passages. Her comfort ratio of 35.41 suggests a motion that favors seakindliness over speed, making extended voyages more pleasant for crew and guests alike. The Ericson 39 B appeals to sailors seeking a well-built, traditional cruising yacht with proven offshore capabilities and the craftsmanship standards that made Ericson Yachts a respected name in American boatbuilding.
