About the Starlight 39 Sailboat

Designed by Stephen Jones and built by David Sadler in the UK, this masthead sloop represents a thoughtful approach to bluewater cruising from the early 1990s. With only 34 hulls constructed between 1990 and 1994, the Starlight 39 remains a relatively rare find on the used boat market. The yacht's substantial displacement of 19,749 pounds and generous beam of 12.50 feet create a stable, seaworthy platform well-suited for offshore passages and extended cruising. Her wing keel configuration reduces draft to 5.33 feet while maintaining excellent stability, making her accessible to more harbors and anchorages than traditional deep-draft designs. The comfort ratio of 31.18 suggests a motion that prioritizes stability over speed, ideal for long-distance cruising where crew comfort is paramount. Performance-wise, the SA/Displacement ratio of 15.67 indicates moderate sailing performance with enough power to move efficiently in light to moderate conditions. The capsize screening formula of 1.85 falls well within acceptable limits for offshore sailing, reflecting the designer's emphasis on safety and seaworthiness. Her fiberglass construction ensures durability, while the 40-horsepower engine provides adequate auxiliary power for maneuvering and motorsailing in calm conditions.
