1981–1987 · designed by Ron Holland · built by Nautor Oy
Ron Holland-designed IOR-era performance cruiser-racer built to Nautor's premium Finnish standard — hand-laid fiberglass, heavily- glassed hull-deck joint, stainless and bronze hardware throughout. Designed for IOR-era racing plus credible offshore cruising. Fixed fin keel with optional shoal-draft keel; internally mounted spade rudder. Available with standard (7.2 ft) or shoal-draft (5.5 ft) keel. Displacement 18,900 lb; accommodates up to 9.
This is a general read on the Nautor Swan 391 class — informed
background, not a verdict on any individual boat. Condition, refit history,
and how a particular hull was sailed and stored matter far more than class
reputation. Use it to know what to look for; for a read on a specific

Nautor build quality is at the top tier of European production — hand-laid hulls, heavily-glassed hull-deck joint, premium hardware throughout. Swans of this vintage typically present materially better than coast-spec contemporaries from the same era.
Ron Holland design heritage — sailing manners and balance praised across owner reviews; Holland's IOR-era designs are known for rewarding handling characteristics.
Strong used-market price retention. The "Swan" brand commands a durable premium — informs negotiation framing (limited downward price flexibility for clean examples).
Manufacturer still in business (modern Nautor Swan) — heritage parts and dealer support remain available in the EU.
Known trade-offs
IOR-era hull form is dated by modern cruising standards — pinched stern, narrow waterline beam, livelier motion than current cruiser- optimised designs of the same LOA.
Premium build = premium service costs. Lewmar / Goiot / Navtec / Volvo parts are all EU-pricing-tier. Refit budgets need to reflect Swan-tier rather than production-tier pricing.
Rod rigging (where fitted) requires specialist inspection — fewer US riggers carry rod-rigging tooling and skills than wire. Plan service location accordingly.
Age-related quirks to expect

Systems to check before you buy
Standing rigging + chainplatespriority: offshore, coastal, racing
Original Navtec rod rigging on most hulls — rod has different inspection criteria than wire (rod can fatigue invisibly at the swage; replacement cycle ~15-20 years for offshore use, vs. wire 25-30). Chainplates are stainless and bolted through bulkheads; check for crevice corrosion at deck-edge penetrations. Keel-stepped mast — bilge water history at the step matters.
Bolt-on lead keel attached with stainless bolts through a glassed hull stub. By 40+ years inspect keel-hull joint for the classic "smile" crack pattern. Keel-bolt corrosion (galvanic via bilge water) is the underlying concern; full bolt audit recommended for offshore use.
Engine (original Perkins diesel per factory fit)priority: offshore, coastal, liveaboard
Wikipedia notes the original factory engine as a Perkins diesel. At 40+ years, original engines are at end-of-life unless service records prove otherwise. Repower to a modern Yanmar or Beta Marine is a common upgrade on Swans of this vintage.
Original bronze fittings on a 40+ year hull. Nautor build quality means bonding + backing blocks are generally sound, but the fittings themselves are at age limit. Routine replacement during a haul-out.
How it fits your plans
Offshore
Designed for it within the IOR-era performance-cruiser-racer framing. Multiple class Bermuda Race / transatlantic finishers — proven offshore platform. Modern cruising sailors should expect somewhat livelier motion than a heavy-displacement full-keel boat of the same LOA.
Coastal
Excellent. Balanced rig, S&S sailing manners universally praised. The Swan reputation carries a price premium harder to justify if used only coastally.
Liveaboard
Workable but not optimised. IOR-era pinched-stern form and racer-cruiser interior layout sacrifice volume vs. more cruiser-oriented designs of the same LOA.
Racing
Original design intent. Still campaigned in classic-yacht and IOR- revival fleets; sailing performance remains competitive in its class.
