Designed by the respected team of Graham & Schlageter, this 30-foot cruiser emerged during the mid-1980s boom in affordable fiberglass sailboats. S2 Yachts built 127 hulls between 1983 and 1987, creating a modest but dedicated following among sailors seeking a capable coastal cruiser with solid construction values. The masthead sloop rig and moderate proportions reflect classic cruising priorities, with a fin keel and transom-hung rudder configuration that balances performance with practicality. At 7,850 pounds with 3,200 pounds of ballast, the boat carries enough weight for stability while maintaining reasonable trailer ability for those willing to tackle the logistics of a near-30-footer. With a sail area to displacement ratio of 19.91, this design falls squarely in cruising territory rather than racing-oriented performance. The moderate beam of 10.5 feet provides comfortable interior volume without sacrificing sailing characteristics, while the 5.5-foot draft offers good windward ability for coastal exploration. The comfort ratio of 20.02 suggests lively motion in seaways, making this better suited for day sailing and coastal cruising rather than extended offshore passages. The low capsize screening value of 2.12 indicates good initial stability, while the 15-horsepower auxiliary provides adequate power for maneuvering in tight quarters.
