About the Offshore 40 Nautical Development Sailboat

Built during a brief three-year production run from 1983 to 1985, this distinctive 40-footer represents the collaborative design work of Raymond Creekmore and Steve Lippincott for Nautical Development. With only 14 hulls constructed, the Offshore 40 stands as a relatively rare find in today's used boat market. The yacht's design philosophy clearly emphasizes serious offshore capability, evidenced by its robust 21,500-pound displacement and substantial 9,000-pound ballast ratio. The fin keel and spade rudder configuration provides responsive handling characteristics while maintaining the directional stability crucial for extended passages. At nearly 40 feet overall with a 35-foot waterline, the hull generates a theoretical hull speed of 7.93 knots, making her well-suited for comfortable passage-making. The masthead sloop rig carries 740 square feet of sail area, delivering a moderate sail area-to-displacement ratio that favors steady performance over racing speed. Her comfort ratio of 29.25 suggests motion characteristics that lean toward the gentler end of the spectrum, while the capsize screening formula of 1.91 indicates good stability margins for offshore work. This combination of specifications points to a yacht designed primarily for serious cruising couples or small crews seeking a capable, seaworthy platform for extended coastal and offshore adventures.
