The Swan 65S&S Ketch is the largest hull Nautor Swan ever put into serial production. Designed by Sparkman & Stephens, this 64foot yacht bridged the early fiberglass era and the marque’s first great ocean races. Nautor built just 41 examples in Finland between 1972 and 1989. At its launch, it was the largest glassfibre yacht on the market, and it remains a benchmark offshore ketch.

Its racing pedigree is undisputed. Sayula II won the inaugural 1973/74 Whitbread Round the World Race, while Swan 65s finished second and fifth in the 1977/78 edition. In the 1977/78 edition, Kings’ Legend finished second under Nick Ratcliffe, with Skip Novak as navigator.

Design and Construction

The 19.68-meter hull is solid GRP, with a flush deck and a traditional, sleek cut-out stern. That profile makes the boat appear even longer than its 14.33-meter waterline suggests. The deck and deckhouse are foam-cored sandwich, sheathed in fiberglass and finished with teak on the walking surfaces.

The wheelhouse sits almost fully aft. Its deckhouse line runs from the main mast to the stern, protecting the cockpit. Fiberglass structural reinforcements run along the hull to stiffen load-bearing components, and the keel is a hung and bolted fin.

The first 19 hulls displaced 31.8 tons and carried 10 tons of lead ballast. Later boats exceeded 35.3 tons, with 13.9 tons of ballast. That changed the displacement-ballast ratio from 31 percent to 39 percent.

Rig and Handling

The Swan 65 was primarily built as a ketch, spreading the sail area between two masts and helping balance the boat, but it was also offered as a sloop. Both versions have through-deck aluminium masts, stainless steel standing rigging, and a masthead forestay. The main mast has two pairs of spreaders; the mizzen has one.

The ketch carries a 57.6 m² mainsail, a 25.3 m² mizzen, and a 126.3 m² 150% genoa. A 66.4 m² mizzen staysail was optional. Its 303 m² spinnaker is flown from a 7-meter pole, with one pole carried on each side. The sloop has a larger 78 m² mainsail and 141.4 m² genoa, along with a 339 m² spinnaker.

Writing in Yachting World, Tracy Edwards called the hull beautiful and gorgeous to sail. A top speed of 14 knots was documented.

Machinery and Tankage

The engine sits amidships in the dinette, just above the bilge. It can be reached from either side below the floorboards. Engine options over the production run included the Volvo Penta MD32 (89 hp), Perkins H6.354M (115 hp), and TMD41A (148 hp).

The boat carries 1000 liters of fuel and 757 liters of water, reflecting its focus on long passage-making rather than coastal hopping.

Accommodations

The Swan 65’s interior compartments were carried over from the Swan 55. The main access is located one-third of the way between the masts and opens into a dinette, with the galley to port and chartroom to starboard.

In the saloon, a large C-shaped settee wraps around a center table, with a second settee opposite. The galley is sized for only one or two people to work in it.

Forward are two twin cabins, each with staggered single bunks and a private head. The cabin in the extreme bow normally serves as sail stowage but can accommodate two berths. Aft is a full-beam master stateroom with a private bathroom, chart space, and an optional second berth.

The stated layout provides 3 plus 1 cabins, 6 plus 4 sleeping places, and 3 heads. Ceiling-mounted handrails run the full length of the interior, and all corners are blunted for safety at sea. Edwards described the woodwork as sublime and the interior as one in which a person could live aboard forever.

Deck and Crew Work

The flush deck and aft wheelhouse suit a crew working the twin spinnaker poles and aft winches mounted at the cockpit-shoulder interface. The protected cockpit and divided sail plan also reflect the boat’s offshore purpose.

Known Issues

The foam-cored deck and deckhouse, with fiberglass skins and teak above, require careful inspection for water ingress around fasteners.

The hung and bolted keel attaches through the hull, so the keel bolts require periodic inspection. The engine’s low position in the dinette places the machinery above the bilge. Although the engine is accessible from each side below the floorboards, its low position can complicate bilge access, and bedding and seal integrity remain the owner’s responsibility.

Refits and Ownership

Owning a Swan 65 means looking after a low-volume hull that meets the era’s IOR Mk III rule standards. The three original engine variants give buyers flexibility when repowering, while the choice between ketch and sloop rigs has a major effect on sail inventory.

The Verdict

The Swan 65-S&S is a genuine bluewater icon: a Sparkman & Stephens yacht with Whitbread race success, a solid GRP hull, and a voluminous interior derived from the Swan 55. It is large, heavy, and purpose-built, rewarding owners who place more value on provenance and passage capability than on modern conveniences.

Pros

  • Largest Nautor Swan hull ever built; only 41 were made
  • Whitbread-proven offshore pedigree, including victory in 1973/74
  • Solid GRP hull with fiberglass structural reinforcements
  • Choice of ketch or sloop rig
  • Generous sail area and twin spinnaker poles
  • Full-beam aft master stateroom and twin forward cabins
  • Capacity for up to 12 berths

Cons

  • Foam-cored deck requires vigilance for water intrusion
  • Hung-keel bolts need periodic inspection
  • Low engine position can complicate bilge access despite access from each side below the floorboards
  • Later hulls are heavy, exceeding 35.3 tons, with a 39 percent displacement-ballast ratio
