For buyers and enthusiasts, the Swan 57 offers a study in late-1970s fiberglass construction, a classic racing-style interior, and a hull form whose good looks have aged remarkably well.
Design and Lineage
The Swan 57 carries the visual hallmarks that made S&S Swans so recognizable: a raked bow, modest sheerline, low freeboard, wide decks, the classic rocket-ship stern, and a reverse transom.
Nautor built the boat predominantly of glassfibre with wood trim. Both hull and deck are solid fiberglass rather than cored laminate. The Swan 57 is a monohull with either a fixed fin keel or an optional stub keel and centreboard. A wheel controls the skeg-mounted rudder.
Introduced in 1977 as a racer-cruiser, she measures 57.4 feet overall and 45.8 feet on the waterline, with a 15.85-foot beam. Displacement is roughly 49,500 pounds, including 18,900 pounds of lead ballast. Those proportions place her firmly in the serious offshore cruiser-racer class.
The S&S–Nautor Split
The Swan 57 wasn’t just another model. It became the centerpiece of the falling-out between Nautor and Sparkman & Stephens. Arguments over its design and construction culminated in the separation of the two companies, and S&S has not designed another Swan since the boat’s 1977 introduction.
The rupture had a specific origin in the Swan 57 itself. The earliest couple of hulls had a floor-framing issue and didn’t handle stress correctly under testing. Nautor took its complaints to S&S. After reviewing the matter, S&S said Nautor had misinterpreted the specifications and built the boats incorrectly. Nautor, in turn, was offended that S&S didn’t accept responsibility.
Despite the dispute, Nautor continued building the Swan 57 until 1984, completing all 49 hulls.
Rig and Handling
The Swan 57 was offered as either a ketch or a masthead sloop. The ketch carries a boomkin for the mizzen mainsheet.
With the ketch rig and fixed keel, she has a PHRF handicap of 57. The centreboard ketch rates from 54 to 60, while the fixed-keel sloop version spans 21 to 63.
Owners report that the Swan 57 will reach hull speed in 10 to 15 knots of wind. They also report that upwind she can sail unattended for eight-hour stretches, reflecting a balanced helm and predictable manners.
The boat is sometimes confused with the unrelated 1990 Swan 57CC Frers or the 1996 Swan 57 RS. Both are distinct designs from a later era.
Accommodations
Below, the Swan 57 is unapologetically a classic racing type rather than a floating condominium. There is no centerline queen berth in the aft stateroom, and the layout sleeps six to nine, depending on configuration.
The three-stateroom arrangement includes a double V-berth in the bow cabin and a midship guest stateroom with upper and lower berths. The master stateroom has a slide-out double berth to port and a single berth to starboard.
In the main saloon, a U-shaped settee faces a straight settee. The dining table has an expanding teak top and seats eight. The C-shaped galley is to port, abeam of the companionway ladder, and includes a three-burner stove, an ice box, and a double sink. The navigation station is opposite, to starboard.
Two heads serve the accommodation plan: one just aft of the bow cabin and another aft to port.
Construction and Ownership Considerations
The best-documented structural concern is the floor-framing problem found in the earliest hulls. Their stiffening support structure wasn’t right, and the floors weren’t designed or built correctly. Any surviving early boat warrants close inspection in this area.
Teak decks were optional when new. On a 57 Swan, the teak has to be replaced if it hasn’t already been renewed, making deferred deck work a substantial ownership cost.
The original engine is a 73 HP Perkins diesel. Generator placement is also worth noting. Owners have often installed the unit aft, where it intrudes on the aft staterooms and creates noise there.
The Verdict
The Swan 57 S&S Ketch is a handsome, capable racer-cruiser that closed the Sparkman & Stephens era at Nautor. Her lines remain among the prettiest in any harbor three decades on, and her sailing manners reward confident handling.
The framing dispute affecting the earliest hulls and the cost of teak-deck renewal are the principal caveats. Even so, the design’s completeness and limited production make the Swan 57 a collectible example of late-1970s Swan craft.
Pros
- The final and definitive S&S-designed Swan, with the classic rocket-ship stern and low freeboard
- Balanced ketch or sloop rig, with documented unattended upwind capability
- Racing-style interior with three staterooms, a proper seagoing galley, and a navigation station
- Solid fiberglass construction with a lead-ballasted fin keel or centreboard configuration
Cons
- The earliest hulls had floor-framing problems under stress
- Teak decks, if original, require full replacement
- Aft-mounted generators on owner boats create noise in the aft staterooms
- No centerline queen berth aft; the interior follows a dated racing style rather than a modern cruising layout
