The Swan 371 stands as one of Ron Holland's earliest commissions for the Finnish yard, a 37foot masthead sloop conceived in the late 1970s as a racer with real cruising accommodations. Fewer than 100 were completed before the tooling was retired, and the design captures a precise moment when Nautor's production philosophy met a young New Zealand designer's eye for an IORinfluenced hull.

Design and Construction

Ron Holland drew the Swan 371 for racing, and Nautor built it from 1979 onward at the Finnish yard, with 87 boats completed by the time production ended anchor. The hull is fiberglass, with teak wood trim throughout and all woodwork above and below decks made from teak. The keel is a fixed fin carrying 5,700 lb of lead ballast, and the rudder is an internally mounted spade type controlled by a wheel. A raked stem and raised reverse transom give the profile its period character. At 11.28 m overall with a 9.06 m waterline and 3.46 m beam, the boat displaces 16,100 lb and draws 6.8 ft on the standard keel — a ballast ratio near 37 percent and a length-to-beam ratio of 3.25 place her firmly in the moderate-racer category with a DL-ratio of 259 anchor.

Rig and Handling

The Swan 371 carries a masthead sloop rig with a 14.26 m I foretriangle and a 12.50 m mainsail luff, the reference sail plan yielding a sail-area-to-displacement ratio of 15.4 that climbs to 18.6 with a 135 percent genoa anchor. Genoa tracks are inboard and an additional deck eye is fitted for a staysail, while two halyard winches sit on the coach-house roof, two genoa sheet winches on the cockpit coaming, and two further winches serve spinnaker sheeting. The capsize screening value of 1.82 and a Motion Comfort Ratio of 29.1 describe a stiff, seaworthy hull whose theoretical hull speed of 7.31 knots matches the displacement-length physics; the wetted surface of about 409 sq ft and an immersion rate of 1,181 lb per inch speak to a hull that holds her lines under load.

Accommodations

Below, the Swan 371 is laid out around a large master cabin, with a forward cabin given over to sail stowage and two pipe berths. Two berths sit in the transom, a single and a double quarter berth extend sleeping capacity, and one or optionally two pilot berths fill out the roster. The main cabin's drop-leaf table can be removed and stowed to clear the sole, the head carries a hand-held shower and skylight, and the galley holds an ice chest that may be optionally electrically refrigerated. The navigation station opposite the galley has under-table chart stowage, and ventilation comes from a foredeck hatch, two opening main-cabin ports, and an opening cockpit port.

Equipment and Deck Layout

On deck the boat is fitted with a British Bukh 20 hp diesel, a 37-gallon fuel tank, and a 66-gallon water tank. Liferaft stowage is provided on deck, and the standard winch complement supports a versatile headsail program from genoa to spinnaker. The wheel-steered spade rudder and fin keel give predictable response, and the 2.07 m draft limits her to major marinas.

The Verdict

The Swan 371 is a limited-series Holland design that blends IOR-era race potential with a genuinely livable teak interior. Her numbers describe a moderate racer with strong stability indices and a hull speed consistent with her length, while the accommodation plan shows real cruising intent without sacrificing the sail-locker-forward race bias.

Pros

  • Designed by Ron Holland and built by Nautor in limited numbers (87 completed)
  • Lead-ballasted fin keel with spade rudder and 37% ballast ratio for stiffness
  • Versatile masthead rig with inboard genoa tracks, staysail eye, and six winches
  • Removable main-cabin table and sail-locker forward reflect dual-purpose layout

Cons

  • 6.8 ft draft restricts her to deeper marinas
  • Original Bukh diesel is a period unit with no upgrade path described in the sources
  • Low SA/D of 15.4 under reference sail means she is genoa-dependent in light air
