Design and Construction
Nautor built the Swan 39 in Finland as a monohull of solid fibreglass with wood trim, carrying a fixed fin keel and an internally mounted spade rudder steered by a wheel. The hull shows a raked stem and reverse transom, and at 39.3 feet overall with a 31.5-foot waterline the boat carries a length-to-beam ratio of 3.14 and a displacement-length ratio of 252, a figure that places her among moderate racers rather than heavy displacement cruisers. Her 18,000-pound displacement carries 7,900 pounds of lead ballast, a 43.9 percent ballast-displacement ratio that explains much of her composure. The capsize screening value of 1.92 sits below the threshold where, by that formula alone, she would be accepted for ocean racing, and her Motion Comfort Ratio of 27.7 reflects a hull tuned more for velocity than for flat-water gentility. Immersion runs about 1,372 pounds per inch, so loading her is felt quickly in the waterline.
Rig and Handling
The Swan 39 is a masthead sloop on a Bermuda rig, with a sail area of 761 square feet and a PHRF handicap ranging from 78 to 87—quick for a 39-footer of her era. A symmetrical spinnaker may be carried for downwind work. Her theoretical hull speed is 7.5 knots, the figure expected of a displacement hull at this length, and the spade rudder with wheel steering gives the precise control a race-derived hull rewards. The combination of fin keel, moderate beam, and high ballast ratio produces a boat that tracks like a racer but carries the stability to cruise.
Accommodations
The cruising layout sleeps eight. A double V-berth occupies the bow cabin, while the main cabin holds two straight settees around a drop-leaf table and two pilot berths. Two aft cabins each contain a single berth. The galley sits to starboard at the companionway ladder in a straight configuration with a three-burner stove, ice box, and sink; opposite it to port is the navigation station. The head is just aft of the bow cabin on the port side. This is a race-influenced interior that still supports a family or short-handed crew without contortion.
Known Issues
Only 33 were built and production has ended, so any repair requiring a sister-ship part or a hull-specific casting means custom work rather than a chandlery shelf. The solid fibreglass hull and wood trim are the two materials whose aging must be judged per-hull, since the wood trim is the only non-glass component the sources name.
Refits and Ownership
Ownership of a Swan 39 means joining a very small cohort. The Perkins 4-108 diesel is fitted for docking and maneuvering, a robust period engine but one now decades past its design life on most hulls. An Italian Swan 39 named Black Swan won the overall title at the first Swan World Cup, a marker of the class's competitive pedigree. With only 33 boats and a Holland design lineage, the 39 rewards an owner who values rarity and race-derived handling over production-support convenience.
The Verdict
The Swan 39 is a limited-production Holland design that brought IOR race DNA into Nautor's cruising range without sacrificing livability. She is quick, stable for her size, and rare to the point of being a collector's cruiser-racer.
Pros
- First Ron Holland design built by Nautor, with direct IMP Admiral's Cup lineage
- High ballast ratio and capsize screening suited to offshore and coastal sailing
- Eight-berth cruising layout with proper nav station and straight galley
Cons
- Only 33 built; parts and hull-specific support are scarce
- Moderate-racer DL ratio means less load-carrying comfort than heavier cruisers
- Perkins 4-108 now requires vigilant engine-life management
