The Swan 57 S&S CB stands as a definitive milestone in the lineage of Nautor’s Swan, representing the final grand collaboration between the Finnish shipyard and the legendary design firm Sparkman & Stephens. Produced between 1977 and 1984, with a total of 49 hulls launched, this model was conceived as a powerful ocean voyager capable of crossing any sea in safety and comfort. The "CB" designation refers to the centerboard configuration, a highly sought-after variant of the standard deep-keel model. This design choice was specifically engineered to provide the yacht with a versatile draft—approximately 6 feet with the board up—allowing access to the shallow anchorages of the Bahamas and the Chesapeake Bay that are typically off-limits to vessels of this displacement. Built during what many enthusiasts call the "bulletproof era" of Nautor, the 57 features a heavily reinforced solid fiberglass hull and an interior that serves as a masterclass in traditional joinery.

Sailing Performance & Handling
Under sail, the Swan 57 S&S CB is a quintessential heavy-displacement cruiser that prioritizes momentum and sea-kindliness over light-air agility. With a displacement approaching 50,000 pounds, the yacht possesses a motion at sea that is famously described as "regal," brushing aside chop that would toss lighter modern yachts. The hull form, derived from Sparkman & Stephens' extensive experience in offshore racing, features a sharp entry and a long, traditional fin keel (into which the centerboard is housed) that provides exceptional directional stability.
According to the Sparkman & Stephens Design Office, the Swan 57 (Design No. 2308) was offered with both ketch and sloop rig configurations. The centerboard version does not sacrifice upwind performance; when the board is fully extended, the yacht finds deep-water "bite" that allows it to point surprisingly high for a cruiser of its vintage. However, owners frequently note that the boat truly comes alive on a reach. The generous sail area-to-displacement ratio ensures that once the yacht is powered up, it tracks with remarkable precision, requiring minimal helm correction even in building following seas.
Interior Comfort & Variations
The interior of the Swan 57 is a sanctuary of hand-rubbed Burmese teak and high-quality textiles, reflecting the uncompromising standards of Finnish craftsmanship. The layout was designed for long-term habitation, featuring a spacious master suite aft with a private companionway to the cockpit—a hallmark of the larger S&S Swans. The main saloon is characterized by its warmth and functional elegance, often configured with a large U-shaped settee to port and a straight settee or pilot berths to starboard, providing secure sleeping arrangements for off-watch crew during passages.
Sibling variations on this hull are notable; while the centerboard version is the focus here, the standard fixed-keel Swan 57 draws over 9 feet, offering slightly more stiffness in heavy air at the cost of cruising versatility. Furthermore, Nautor offered the "RS" or Raised Saloon variant in very limited numbers for later models in the 50-foot range, though the 57 largely maintained its classic low-profile coachroof. The galley is a traditional offshore "U" shape, located to port of the companionway, providing a safe brace point for the cook even at high angles of heel.
Popular Mentions & Media
The Swan 57 occupies a revered space in the history of the Whitbread Round the World Race (now the Ocean Race). While the earlier Swan 65 Sayula II famously won the inaugural race, the 57 was often the vessel of choice for serious privateers and high-latitude explorers of the 1980s. The model’s reputation for indestructibility was further cemented by its frequent appearances in technical sailing journals like Yachting Monthly, which has historically lauded the S&S Swans for their "unrivaled build quality" and "timeless aesthetic."
Known Issues & Buyer’s Checklist
Purchasing a Swan 57 S&S CB requires a sophisticated survey, as the systems and materials are now entering their fifth decade of service.
- Centerboard Mechanism: The hydraulic or manual lift system for the centerboard must be inspected for galvanic corrosion and the condition of the pennants. The trunk itself can be a site for marine growth that hinders operation.
- Teak Deck Integrity: Like most Nautor yachts of this era, the teak decks were originally bedded and screwed. Over time, thinning wood and failing bungs can lead to water intrusion into the deck core. Buyers should check for "popped" screws and moisture readings around the chainplates.
- Rod Rigging: Most 57s were originally equipped with Navtec rod rigging. Since rod rigging has a finite fatigue life (often 10–15 years depending on use), many older hulls are due for a complete standing rigging replacement.
- Engine Access and Plumbing: While the engine room is large, the complexity of the original plumbing—often featuring gate valves and copper piping—may require modernization to meet current ABYC standards and ensure reliability.
Community & Resources
Owners of the 57 are supported by a robust network of specialists and fellow sailors. The S&S Swan Association is the primary repository for technical drawings, hull-specific histories, and maintenance wikis. This organization hosts "Swan Cups" and regattas that celebrate the heritage of these Sparkman & Stephens designs, ensuring that parts availability and technical knowledge remain accessible to modern owners.
The Verdict
The Swan 57 S&S CB is a yacht for the traditionalist who refuses to compromise on seaworthiness or aesthetics. It remains one of the few vessels capable of world cruising that retains its value through its pedigree and the enduring appeal of the Sparkman & Stephens lines.
- Pros: Exceptional build quality; versatile shallow-draft capability; superior heavy-weather tracking; iconic classic status.
- Cons: High maintenance costs for teak and rigging; heavy displacement makes it slow in light air; the centerboard trunk requires specialized maintenance.
