S2 9.1 Information, Review, Specs

The S2 9.1 emerged during a period when S2 Yachts, founded by Leon Slikkers, was renowned for its commitment to quality fiberglass construction and efficient production methods. Graham & Schlageter designed the 9.1 specifically to the MORC rule, a design philosophy that emphasized performance in offshore racing for smaller boats. This rule often encouraged designs that were quick, maneuverable, and responsive. S2 Yachts leveraged their advanced manufacturing facility, which was noted for its climate-controlled environment and early adoption of innovative techniques like incorporating fabric into their fiberglass construction, ensuring a consistent and high standard of build quality for the 9.1. While the standard S2 9.1 featured a fin keel with a 5.5-foot draft, a shallow draft version was also available, drawing 4.5 feet. The production run saw 127 units built before S2 Yachts largely shifted its focus from sailboat manufacturing in 1989.

Sailing Performance and Handling

The S2 9.1 exhibits characteristics of a capable cruiser-racer, balancing speed with stability. With a sail area to displacement ratio of approximately 19.5, the S2 9.1 is well-equipped for good performance in lighter winds, suggesting it can accelerate quickly and maintain speed even when the breeze is modest. Its ballast to displacement ratio of about 0.41 (41%) indicates a stiff and stable boat, capable of standing up to more wind without excessive heel, contributing to a comfortable motion in a seaway. The displacement to length ratio of around 224 places the S2 9.1 in the moderately light category, suggesting a performance-oriented design without being overly extreme. Owners frequently praise the S2 9.1's excellent handling and control, noting its responsiveness, particularly with tiller steering. The boat is generally considered to sail well in all wind conditions, though some opinions suggest it performs best in medium air. Its fin keel provides splendid maneuverability. The theoretical hull speed is estimated at 6.7 knots.

Accommodations and Layout

While specific details on the S2 9.1's interior are best gleaned from individual boat surveys and reviews, common layouts for boats of this era and size typically include a V-berth forward, a main salon with opposing settees that can often convert into berths, a galley, and a head. The 9.1 is equipped with a 15-gallon fresh water capacity. Interior finish quality from S2 Yachts was generally well-regarded, known for robust construction. Owners note that some S2 9.1s were better appointed for cruising, with variations in head layouts. The forepeak can be easily removed, indicating some flexibility in the forward cabin arrangement.

Owner's Perspectives

Owners of the S2 9.1 consistently express satisfaction with its solid construction and overall sailing capabilities. Many highlight its excellent handling, balance, and responsiveness, making it a joy to sail, particularly for those accustomed to tiller-steered boats. The 9.1 is often lauded for its ability to single-hand cruise with ease, especially if equipped with upgrades like larger winches. While generally well-built, some owners have noted recurring issues such as potential structural repairs needed at the mast step or on the keel fastening, which may involve a mild steel plate glassed into the hull. Despite these potential maintenance considerations, the S2 9.1 maintains a strong following, with many owners appreciating its design as a capable racer/cruiser that offers good interior volume for its size.
