Design and Construction
Ron Holland drew the Swan 371 for racing, and Nautor began building it at its Finnish yard in 1979. Production ended after 87 boats had been completed.
The fiberglass hull has a raked stem and raised reverse transom, giving the boat a profile typical of its period. All woodwork above and below deck is teak, with teak trim used throughout.
The Swan 371 measures 11.28 m overall, with a 9.06 m waterline and 3.46 m beam. It displaces 16,100 lb and draws 6.8 ft with the standard keel. Its fixed fin keel carries 5,700 lb of lead ballast, producing a ballast ratio of about 37 percent. The length-to-beam ratio is 3.25, and the DL-ratio is 259, placing the boat firmly in the moderate-racer category. Steering is by wheel through an internally mounted spade rudder.
Rig and Handling
The Swan 371 has a masthead sloop rig, with a 14.26 m foretriangle height and a 12.50 m mainsail luff. The reference sail plan gives a sail-area-to-displacement ratio of 15.4, rising to 18.6 with a 135 percent genoa.
Inboard genoa tracks support the headsail plan, and an additional deck eye is fitted for a staysail. Two halyard winches sit on the coach-house roof, two genoa-sheet winches are mounted on the cockpit coaming, and two more winches handle spinnaker sheets.
The capsize screening value of 1.82 and Motion Comfort Ratio of 29.1 describe a stiff, seaworthy hull. The theoretical hull speed is 7.31 knots, consistent with its displacement and waterline length. A wetted surface of about 409 sq ft and an immersion rate of 1,181 lb per inch indicate a hull that holds its lines under load.
The reference SA/D of 15.4 is low enough to make the boat dependent on its genoa in light air. With the larger headsail set, however, the ratio rises substantially.
Accommodations
Below deck, the layout centers on a large master cabin. The forward cabin is devoted to sail stowage and includes two pipe berths, preserving a clear racing bias in that part of the boat.
Two berths are located in the transom, while single and double quarter berths add to the sleeping capacity. One pilot berth is provided, with a second available as an option.
In the main cabin, the drop-leaf table can be removed and stowed to open up the sole. The head includes a hand-held shower and a skylight. Opposite the galley, the navigation station provides chart stowage beneath its table. The galley has an ice chest, which may optionally be electrically refrigerated.
Ventilation comes from a foredeck hatch, two opening ports in the main cabin, and an opening cockpit port.
Machinery, Tankage, and Deck Equipment
The Swan 371 is fitted with a British Bukh 20 hp diesel. Fuel capacity is 37 gallons, and the water tank holds 66 gallons. The original Bukh is a period engine, and the sources describe no upgrade path.
Liferaft stowage is provided on deck. The standard six-winch arrangement supports a flexible headsail program ranging from genoa to spinnaker. The wheel-steered spade rudder and fin keel give predictable response, although the 2.07 m draft limits the boat to major marinas.
Verdict
The Swan 371 is a limited-production Ron Holland design that combines IOR-era racing potential with a genuinely livable teak interior. Its numbers place it among moderate racers, with strong stability indices and a theoretical hull speed appropriate to its length. At the same time, the accommodation plan shows real cruising intent without giving up the race-oriented forward sail locker.
Pros
- Designed by Ron Holland and built by Nautor in limited numbers, with 87 completed
- Lead-ballasted fin keel, spade rudder, and about 37 percent ballast ratio provide stiffness
- Versatile masthead rig with inboard genoa tracks, a staysail eye, and six winches
- Removable main-cabin table and forward sail locker reflect the boat’s dual-purpose layout
Cons
- The 6.8 ft draft restricts the boat to deeper marinas
- The original Bukh diesel is a period unit, with no upgrade path described in the sources
- The reference SA/D of 15.4 makes the boat dependent on its genoa in light air
