About the Stellar 30 Sailboat

Designed by James H. Kyle and built by Stellar Technology starting in 1984, this 30-footer represents a well-balanced approach to coastal cruising and club racing. The fiberglass construction features a fin keel with transom-hung rudder configuration that provides responsive handling while maintaining structural simplicity for easier maintenance. With a displacement of 5,800 pounds and 2,000 pounds of ballast, the Stellar 30 strikes a nice middle ground between performance and stability. The masthead sloop rig carries 398 square feet of sail area, delivering a sail area-to-displacement ratio of 19.79 that suggests spirited performance without being overly aggressive. The moderate beam of 10 feet provides adequate interior volume while keeping the boat manageable for smaller crews. The comfort ratio of 15.26 indicates this boat will have a quicker motion in seaways compared to heavier cruisers, making it better suited for day sailing and coastal cruising rather than extended offshore passages. The capsize screening formula of 2.23 falls within acceptable limits for coastal sailing, though it suggests caution in heavy weather conditions. Hull speed calculations show the boat capable of 6.87 knots, while the compact 9-horsepower auxiliary engine provides reliable backup power for harbor maneuvering and calm weather motoring.
