The S2 7.0, introduced in the mid-1970s, represents a pivotal era in American boatbuilding where the transition from traditional wood to sophisticated fiberglass construction allowed for a new class of "pocket cruisers." Designed by naval architect Arthur Edmunds, the 7.0 was envisioned as a robust, trailerable family sailboat that did not sacrifice the build quality typically reserved for much larger yachts. At 22 feet 11 inches, it occupies a unique space in the S2 lineup, serving as a more substantial alternative to the S2 6.7 and 6.8 models, while offering a more cruiser-friendly layout than the strictly performance-oriented S2 6.9. The vessel reflects the philosophy of Leon Slikkers, whose commitment to climate-controlled manufacturing and high-grade materials earned S2 Yachts a reputation for producing "the Mercedes-Benz of sailboats" during the 1970s and 80s. This history is preserved by the successor company, which continues to operate under the Tiara Yachts brand today.

Sailing Performance & Handling
The S2 7.0 is characterized by its stiff, predictable handling, a direct result of its generous 1,200-pound lead ballast on a total displacement of approximately 3,100 pounds. This ballast-to-displacement ratio of nearly 39% provides a level of stability often missing in contemporary 23-foot trailer-sailers. With an 8-foot beam—the maximum width allowed for towing without special permits in many jurisdictions—the hull offers a wide footprint that resists heeling in moderate breezes.
On the water, the boat behaves as a classic cruiser-racer. While it lacks the raw acceleration of its more famous sibling, the S2 7.9, the 7.0 tracks exceptionally well thanks to its deep fin keel and well-balanced spade rudder. With a Sail Area/Displacement (SA/Disp) ratio of approximately 19, the vessel has enough power to remain lively in light air without becoming unmanageable when the wind freshens. Owners often report that the boat feels "bigger" than its 23 feet, absorbing chop with a dampened motion rather than the hobby-horsing common in lighter, balsa-hulled competitors.
Interior Comfort & Variations
The interior of the S2 7.0 is a testament to the Slikkers family’s background in high-end cabinetry. Unlike many of its contemporaries that relied on bare fiberglass liners, the 7.0 features extensive teak trim and a thoughtful layout that maximizes its 8-foot beam. The configuration typically includes a V-berth forward, a central main cabin with two settee berths, and a small galley area.
A notable feature for a boat of this size is the "main cabin" feel; the 7.0 was built on the same hull lineage as the S2 7.3, though the 7.3 offered a slightly different deck mold and interior volume. The 7.0’s cabin provides roughly 4 feet 10 inches of headroom, which, while not "standing room" for most adults, is generous for a trailerable boat. Higher-end variants often included a dedicated area for a chemical head tucked under the V-berth cushions. The use of high-quality fabrics and foam during original production means that many well-preserved units still retain an upscale, traditional yacht atmosphere.
Known Issues & Buyer’s Checklist
Prospective buyers should approach the S2 7.0 with a focus on its composite structure and aging hardware. While the hulls are solid fiberglass, the decks utilize a balsa core for stiffness. Over decades, moisture can penetrate the core through improperly sealed deck hardware, leading to "soft spots."
- Deck Delamination: Pay close attention to the areas around the chainplates, stanchion bases, and the mast step. Any flexing underfoot suggests core rot that may require a significant "drill and fill" or skin-peeling repair.
- Mast Step Compression: The S2 7.0 is mast-head rigged, and the downward pressure is transferred through a compression post. Ensure the base of this post and the cabin sole beneath it are not showing signs of crushing or rot.
- Keel Bolt Integrity: The 1,200-pound lead keel is bolted to the hull. Inspectors should look for the "Smile"—a crack at the leading edge of the keel-to-hull joint—which may indicate the need for re-torquing the bolts or renewing the sealant.
- Rudder Moisture: The spade rudder is prone to internal water absorption. Check for weeping rusty water from the bottom of the rudder blade when the boat is hauled out, which indicates the internal steel framework may be corroding.
Community & Resources
The S2 7.0 benefits from a dedicated following among "Good Old Boat" enthusiasts. Technical support is largely found through the S2 Yachts Owner Association, which maintains archives of original brochures and technical manuals. Because many parts were sourced from mainstream marine suppliers like Kenyon (spars) and Harken (blocks), maintaining the 7.0 remains feasible for the DIY owner.
The Verdict
The S2 7.0 remains one of the most balanced pocket cruisers of the late 20th century, offering a blend of "big boat" build quality and "small boat" versatility.
Pros:
- Superior build quality compared to most production 23-footers of the same era.
- Highly stable and forgiving under sail, making it an excellent learner's boat or single-hander.
- The 8-foot beam provides a spacious-feeling interior while remaining legally trailerable.
- Lead ballast (rather than iron) prevents internal rust issues within the keel.
Cons:
- The 3,100-pound displacement requires a substantial tow vehicle (SUV or truck).
- Lack of standing headroom can be limiting for extended coastal cruising.
- Balsa-cored decks require vigilant maintenance to prevent expensive rot issues.
