Black Soo

Designed by renowned Dutch naval architect E.G. van de Stadt in 1957, this 30-foot sloop represents classic European yacht design philosophy adapted for amateur construction. The Black Soo's plywood single-chine hull construction made it an attractive option for home builders during the height of the do-it-yourself boatbuilding movement, contributing to its widespread adoption by multiple builders over the decades. With a displacement of 4,000 pounds and nearly 50% ballast ratio, the Black Soo offers reassuring stability for coastal cruising and club racing. The fin keel with rudder-on-skeg configuration provides good directional control while maintaining reasonable draft for gunkholing. Her masthead sloop rig carries 314 square feet of sail area, delivering spirited performance in moderate conditions with a theoretical hull speed approaching 7 knots. The boat's comfort ratio of 17.1 suggests a relatively stiff motion that favors sailing efficiency over pure comfort, while the capsize screening value of 1.77 indicates good stability margins for coastal and near-offshore sailing. Van de Stadt's design emphasizes seaworthiness and sailing ability over accommodations, making the Black Soo well-suited for day sailing, weekend cruising, and small boat racing where performance matters more than luxury appointments.
