Swan 55-S&S-1970 Yawl Information, Review, Specs

Sailing Performance & Handling

The Swan 55 S&S is a heavy-displacement vessel designed to thrive in heavy weather and open-ocean conditions. With a displacement-to-length ratio that favors stability over light-air acceleration, the boat possesses a "sea-kindly" motion that modern, lighter hulls cannot replicate. The yawl rig configuration is a defining characteristic of this model’s handling profile; the split rig allows for a versatile array of sail combinations, such as the "jigger" (mizzen) and a staysail, which provides exceptional balance when the wind increases and the mainsail needs to be furled or heavily reefed.

Under sail, the 55 tracks with remarkable precision thanks to its deep fin keel and skeg-hung rudder. While the narrow beam (approximately 14 feet) and pinched ends typical of S&S designs of the 1970s limit its performance in downwind surfing conditions compared to modern wide-transom yachts, its upwind performance remains formidable. Documentation from the Classic Swan Association indicates that the 55 was prized for its ability to maintain high average speeds in uncomfortable head-seas, a trait that earned it a reputation as a reliable "mile-eater" for circumnavigators.

Interior Comfort & Variations

The interior of the Swan 55 is a masterclass in traditional Finnish craftsmanship, dominated by hand-rubbed Burmese teak and a layout optimized for life at sea rather than life at the dock. The standard configuration typically features a large V-berth forward, followed by a spacious main salon with pilot berths positioned outboard of the settee—a design choice intended to provide secure sleeping quarters for the crew while the boat is heeling.

The galley is usually situated to port, featuring deep sinks and high fiddles necessary for cooking during offshore passages. To starboard, a substantial navigation station serves as the command center of the vessel. One of the most significant variations across the 16 hulls is the treatment of the aft section; while most feature a dedicated owner’s cabin with a separate companionway for privacy, the specific joinery and electronic integrations often varied based on the original owner's specifications. Unlike the more modern, open-concept "loft-style" interiors, the 55 S&S is compartmentalized, offering a sense of security and numerous handholds that are vital in a rolling seaway.

Known Issues & Buyer’s Checklist

Prospective owners of a 1970s Swan 55 must approach the purchase with an understanding of the maintenance requirements inherent in a 50-year-old classic.

• Teak Deck Longevity: The original decks were often thick, high-quality teak, but they were typically fastened with hundreds of screws into the sub-deck. Over decades, these screws can provide paths for moisture to enter the core. A thorough moisture meter test and "sounding" of the deck are mandatory.
• Mast Step & Rigging: Given the age of the aluminum spars and the complexity of the yawl rig, a full professional rig survey is essential. Owners in the S&S Swan community often report the need to inspect the mast step for galvanic corrosion, particularly where the aluminum meets the steel or lead of the keel structure.
• Osmosis and Hull Blistering: While Nautor used robust laminates, early fiberglass boats are susceptible to osmotic blistering. Many Swan 55s have undergone bottom peels and epoxy treatments; buyers should verify the history of these hull treatments.
• Engine & Systems: Most original Perkins or Volvo Penta engines have either reached the end of their service life or have already been replaced. A modern repower is a significant value-add, as the engine rooms in these models can be tight, making maintenance of older, leak-prone units difficult.

Community & Resources

The primary hub for owners and historians of this model is the Classic Swan Association, a dedicated organization that archives original blueprints, hull numbers, and technical manuals for S&S-designed Swans. This community is instrumental for owners seeking to source period-correct hardware or advice on restoring the vessel to its original racing pedigree. Additionally, Nautor's own "Global Service" division provides a level of historical support rarely seen in the industry, occasionally assisting with the refit of these legacy models.

The Verdict

The Swan 55 S&S Yawl is not a boat for the casual weekend sailor; it is a serious ocean-going machine for those who value pedigree, aesthetics, and a proven track record of seaworthiness. It remains one of the most beautiful silhouettes ever produced by Nautor's Swan.

Pros:

• Exceptional Build Quality: Built during a period when Nautor used overbuilt laminates and the finest timbers.
• Timeless Aesthetics: The S&S lines and yawl rig are widely considered some of the most beautiful in yachting history.
• Ocean Capability: A proven blue-water cruiser capable of handling extreme latitudes and heavy weather.

Cons:

• High Maintenance: The combination of aging fiberglass, extensive teak, and two masts requires a significant annual budget.
• Dated Layout: The narrow beam and pilot-berth arrangement offer less "living room" space than modern 50-footers.
• Rarity: With only 16 built, finding one for sale—and in good condition—can be a multi-year endeavor.
