South Coast Eclipse 6.7 Information, Review, Specs

The Eclipse 6.7 was built on essentially the same hull as its predecessor, the South Coast 22, but featured a modernized deck mold and an updated interior layout. This "sibling" relationship is critical to understanding the vessel; while the hull remained a proven performer, the Eclipse 6.7 aimed to provide a more sophisticated "big boat" feel within a 22-foot footprint. According to technical documentation maintained by the South Coast Owners Association, the Eclipse was produced in much smaller numbers than the 3,000+ units of the original SC 22, making it a relatively rare find on the brokerage market today.

Sailing Performance & Handling

The sailing characteristics of the Eclipse 6.7 are defined by its light-to-moderate displacement and its versatile swing-keel configuration. With a displacement of approximately 2,200 pounds and a sail area of roughly 226 square feet, the boat possesses a Sail Area to Displacement (SA/D) ratio of approximately 21.3. This puts the Eclipse in a high-performance category for a cruising boat, allowing it to accelerate quickly in light air where heavier traditional designs might stall.

Under sail, the boat is known for being responsive, though it can feel tender if over-canvassed. The 700-pound swing keel provides necessary righting moment, but like most trailerables with an 8-foot beam, the Eclipse 6.7 prefers to be sailed relatively flat. Owners often report that the boat tracks well off the wind but requires active mainsheet management when the breeze gusts above 12 knots. The transition from the Alberg-designed SC 21 and 22 models to the Eclipse did not significantly alter the underwater profile, meaning it retains the predictable, forgiving handling that made the original South Coast hulls popular with novice sailors.

Interior Comfort & Variations

The interior of the Eclipse 6.7 was the primary selling point for the model during its production run. By moving away from the traditional low-profile cabin house, South Coast engineers were able to maximize "living" space. The layout typically features a V-berth forward, a compact galley area, and a dinette that converts into an additional berth.

A notable feature of many Eclipse 6.7 models is the implementation of a full fiberglass interior liner. This gave the boat a cleaner, more finished look compared to the raw fiberglass or wood-heavy interiors of earlier decades. While the Eclipse 6.7 lacked the "pop-top" found on some competitors of the era, it compensated with clever storage lockers tucked under the settees and a relatively open-concept cabin that felt larger than its 22-foot length suggested. Variations in the interior were few, as South Coast Seacraft was streamlining production toward the end of its lifespan, though some owners have retrofitted these cabins with modern electrical panels to replace the rudimentary original systems.

Known Issues & Buyer’s Checklist

Prospective buyers should approach the Eclipse 6.7 with a focus on its structural components, many of which are now over 40 years old.

• Swing Keel Assembly: The most critical inspection point is the cast-iron swing keel and its attachment points. The pivot bolt can wear over time, leading to "clunking" or, in extreme cases, failure. The lifting cable and winch mechanism should also be inspected for fraying or corrosion.
• Deck Core Integrity: Like many boats of this era, South Coast used a balsa or plywood core for the deck. Water intrusion through poorly bedded deck hardware (cleats, stanchions) can lead to soft spots. This is particularly common around the mast step.
• Rudder Hardware: The pintles and gudgeons on the transom are known to develop play. Given the age of the fiberglass, stress cracks around the transom mount should be carefully scrutinized.
• Chainplates: The stainless steel chainplates that secure the standing rigging are often bolted through the hull-to-deck joint. Inspect these for signs of "bleeding" or rust streaks, which indicate water penetration and potential weakening of the fiberglass laminate.

Community & Resources

The primary hub for technical data and historical preservation is the South Coast Owners Association (SCOA). This volunteer-run group maintains an extensive archive of original brochures, sail plans, and owner-contributed repair guides. While South Coast Seacraft Co. has been out of business since 1981, the SCOA remains the definitive source for parts compatibility and restoration advice, particularly regarding the specialized swing keel hardware that is no longer in commercial production.

The Verdict

The South Coast Eclipse 6.7 is a nostalgic yet capable pocket cruiser that offers a blend of 1970s "modern" styling and proven hull geometry. It is an excellent choice for sailors who prioritize trailerability and light-air performance without sacrificing a clean, functional interior.

Pros:

• Excellent light-air performance due to a high SA/D ratio.
• Easily trailerable with a standard vehicle, making it ideal for exploring inland lakes.
• Strong community support through the South Coast Owners Association.
• Modern fiberglass liner makes for a low-maintenance interior.

Cons:

• Relatively rare model, making specific replacement parts (like deck molds) hard to find.
• The swing keel requires regular maintenance and mechanical inspection.
• Tender in heavy air; requires early reefing to stay comfortable.
• Common vintage issues like deck delamination are frequently found in neglected hulls.
