S2 7.9 FK Information, Review, Specs

Sailing Performance & Handling

The S2 7.9 FK is widely regarded as a "sailor’s boat," characterized by a high sail area-to-displacement ratio (SA/Disp) that approaches 22.0, placing it firmly in the performance category for a 26-foot vessel. Because the FK model replaces the 600-pound daggerboard and internal trunk with a permanent lead fin keel, the boat exhibits a lower center of gravity and increased righting moment compared to its lifting-keel siblings. This results in a vessel that is significantly stiffer in a breeze and tracks with greater precision upwind.

Handling is exceptionally responsive, owing to a high-aspect spade rudder that provides immediate feedback to the tiller. In light air, the 7.9 FK is nimble, easily reaching its hull speed while other cruisers in its class remain sluggish. According to editorial analysis from SpinSheet Magazine, the boat’s MORC heritage is evident in its ability to plane under spinnaker in heavy air, a rare trait for a boat with a dedicated cruising interior. While it lacks the "beachability" of the standard 7.9, the FK version is often preferred by PHRF racers who want to avoid the maintenance of a daggerboard trunk and the potential for "clunking" in a seaway.

Interior Comfort & Variations

For a boat measuring just under 26 feet, the interior of the S2 7.9 FK is remarkably efficient, though it adheres to the "sitting headroom" constraints of a low-profile racer-cruiser. The absence of the large vertical daggerboard trunk—a mainstay in the standard 7.9—opens up the main salon significantly, creating a more cohesive social space. The layout typically features a V-berth forward, a portable or marine head tucked beneath the cushions, and twin settee berths in the salon that extend aft under the cockpit (quarter berths).

Materials reflect the "Grand Slam" era of S2 production, utilizing teak accents and durable laminates that have aged better than many of their 1980s contemporaries. The FK model was often outfitted with the same "Cruising Package" available on the standard model, which included a small galley with a sink and an alcohol stove. This makes the boat a viable platform for "pocket cruising," provided the crew is comfortable with a compact, minimalist lifestyle.

Popular Mentions & Media

The S2 7.9 series enjoys one of the most robust cultural footprints of any 26-foot sailboat in North America. It is supported by a dedicated One-Design class that remains active in the Great Lakes and the Chesapeake Bay. The model is a frequent subject of technical deep-dives due to its longevity, with the S2 7.9 Class Association serving as the primary repository for tuning guides and class rules. The boat’s competitive longevity is highlighted by its consistent participation in major offshore events, including the Chicago Yacht Club Race to Mackinac, where 7.9s have historically punched well above their weight class in the double-handed and small-boat divisions.

Known Issues & Buyer’s Checklist

Prospective buyers of an S2 7.9 FK should focus their inspection on the structural integrity of the hull and deck, as S2 utilized balsa-core construction extensively to save weight.

• Deck Delamination: Like many boats of this era, the 7.9 is prone to soft spots around the stanchion bases, chainplates, and mast step. A moisture meter is essential to ensure the balsa core remains dry.
• The Keel Joint: On the FK model, the "smile" (a crack at the forward leading edge of the keel-to-hull joint) should be inspected. While often cosmetic, persistent cracking may indicate the need to retorque the keel bolts or reinforce the floors.
• Rudder Post Wear: The high-aspect rudder puts significant stress on the bushings. Excessive "slop" or play in the tiller often requires the replacement of the delrin or nylon bearings.
• Chainplate Bulkheads: Inspect the wooden bulkheads where the chainplates attach. Leaking deck hardware can lead to rot in these structural members, which is a labor-intensive repair.

Community & Resources

The primary hub for this model is the S2 7.9 Class Association, which maintains a technical wiki and organizes annual championships. Owners also frequently congregate within the S2 Yachts groups on broader sailing platforms to share specifications and restoration tips. Because S2 Yachts transitioned into Tiara Yachts, some historical documentation and original parts diagrams can occasionally be sourced through the legacy knowledge of the Tiara Yachts customer service channels, though they no longer provide direct support for the sailing line.

The Verdict

The S2 7.9 FK is an ideal choice for the sailor who wants the thrill of a high-performance sportboat without sacrificing the ability to spend a night at anchor. While it lacks the easy transportability of the lifting-keel version, it compensates with superior stability and a cleaner interior.

Pros:

• Exceptional light-air performance and stiffness due to the fixed lead keel.
• High build quality from a manufacturer known for "over-engineering."
• Strong One-Design class support and resale value.
• Clean interior layout without the obstruction of a keel trunk.

Cons:

• Limited headroom (approximately 4' 11"), making long-term cruising a challenge for tall sailors.
• Requires a deep-water slip and a professional crane for launching/hauling.
• Vulnerable to balsa core rot if deck hardware is not properly re-bedded.
