S2 9.1 SD Information, Review, Specs

The S2 9.1 SD's genesis lies in the early 1980s, with production commencing in 1983 and continuing until 1987. During this period, S2 Yachts, founded by Leon Slikkers, was known for its commitment to high-quality fiberglass construction, leveraging Slikkers' extensive experience in boat building. The company was an early adopter of innovative manufacturing techniques, including incorporating fabric into their processes and crafting hulls in climate-controlled environments to ensure consistent quality. The 9.1 SD, designed by Graham & Schlageter, was specifically developed to excel under the Midget Ocean Racing Club (MORC) rule, which influenced its dimensions and performance characteristics.

While the S2 9.1 primarily features a fin keel with a 4.5-foot draft, there were variations produced, including a "Tall Rig" version that offered an increased sail plan for enhanced performance. Additionally, some "Special Edition" models were noted for alternative interior layouts and a reduced weight, achieved through construction methods like vacuum bagging. It's also worth noting that S2 Yachts transitioned from polyester resin to AME4000 in 1984 to address blister issues observed in some earlier boats, reflecting their commitment to continuous improvement.

Sailing Performance and Handling

The S2 9.1 SD, with its design as a performance cruiser, delivers a balanced and exhilarating sailing experience. Its Sail Area to Displacement ratio stands at approximately 19.91, suggesting good light-air performance. This indicates that the boat is well-powered for its displacement, allowing it to move efficiently even in lighter winds.

With a Displacement to Length ratio of approximately 224.29, the S2 9.1 SD falls into the category of a moderate displacement vessel, striking a balance between the lighter, more sensitive performance boats and heavier, more traditional cruisers. This contributes to its versatility as both a racer and a cruiser. The ballast-to-displacement ratio of about 0.4076, with 3,200 lbs of ballast in a 7,850 lb displacement, suggests a relatively stiff and stable boat capable of standing up to a good breeze without excessive heel.

Owners frequently praise the S2 9.1's excellent handling and control, noting that its semi-balanced rudder provides good steerage without being overly fatiguing, even in heavier conditions. The boat is often described as a "good medium air boat" that sails effectively and is responsive to the helm. Its fin keel with a transom-hung rudder contributes to its maneuverability and control on various points of sail.

Accommodations and Layout

The interior of the S2 9.1 SD is designed to offer a comfortable and functional space, characteristic of S2 Yachts' focus on balancing performance with livability. The layout typically features a traditional arrangement, including a V-berth forward, providing sleeping quarters for two, and an aft quarter berth, often used for additional crew or storage. While specific headroom details are not universally documented, S2 interiors of the era were generally well-finished, often incorporating neutral-colored fabrics and practical materials.

The galley is typically compact but functional, designed for preparing meals during coastal cruises. Storage solutions are integrated throughout the cabin to accommodate provisions and personal gear. The fresh water capacity is around 15 US gallons (57 liters), which is adequate for weekend trips or short coastal passages. Overall, the accommodations prioritize efficiency and comfort, reflecting its dual role as a racer and a cruiser, providing essential amenities without excessive bulk.

Owner's Perspectives

Owners of the S2 9.1 SD consistently highlight its solid construction and seaworthiness, which are hallmarks of S2 Yachts' building ethos. Many appreciate its comfortable motion in a seaway and its ability to perform well in various conditions. The boat is often considered an excellent choice for single-handing due to its manageable size and responsive handling.

However, some common issues have been noted over the years. Early models (pre-1984) sometimes experienced blister problems, which S2 addressed by switching resin types. Another recurring maintenance concern for some owners is the lifting and cracking of the deck area around mast partners, which may require re-bedding. Engine issues, particularly with the original Yanmar 13hp, have also been mentioned in owner forums. Despite these potential points of maintenance, the S2 9.1 SD continues to be admired by enthusiasts for its overall quality, sailing characteristics, and the enduring legacy of a well-built American sailboat.
