Design and Construction
Nautor built the 45 at its Boatbuilding Technology Centre in Jakobstad, Finland, turning out hulls at a rate of one every other week. The deck and topsides use a balsa core, while the bottom is a carbon-fiber-reinforced solid laminate; Swan had not built a cored bottom at that point. On deck the visual language recalls midsize Swans of the 1980s but is updated: a cabin trunk emerges from the foredeck and grows gracefully to the cockpit, softer and higher than the older trunks, with two narrow nearly rectangular portlights per side lighting the saloon. Decks are paved in honey-color teak, and an open transom is standard, though a drop-in closure is offered for cruising security. The 45 is 45.37 feet overall, 39.60 on the waterline, with a 12.83-foot beam and a light draught of 9.19 feet rising to 9.45 loaded.
Rig and Handling
The fractional sloop rig carries a carbon mast tuned by a hydraulically adjustable permanent backstay that sets forestay tension and mast bend, while two sets of swept spreaders and a full-beam staying base remove any need for running backstays. An adjustable mast step hidden in the bilges lets the crew shift the mast foot fore and aft. Most control lines run in tunnels beneath the deck and coachroof; the genoa track sits close to the trunk cabin, and the sheet-lead line runs aft through fairleads on the trunk sides. The continuous mainsheet runs from the traveler up and along the boom to prevent side-to-side trimming imbalance, then ducks into a deck tunnel and emerges at a winch forward of the helm, with traveler and mainsheet winches within the helmsman's reach. A 60-inch wheel bisects the after cockpit and links to a smooth manual steering system of Vectran cables and a quadrant, letting the helmsman sit outboard either side. The class actively encourages owners to steer, though provision exists for Group 1 or 2 helms if an owner hands over.
Accommodations
Below, the 45 offers three interior style choices and a hand-rubbed satin finish that invites casual use rather than museum care. An off-white vinyl overhead brightens the space and makes the teak glow under hatch and portlight light. Generous fiddles on counters and large radii on furniture corners show the cruising intent, and a dedicated wet locker sits abaft the starboard nav station. The cockpit sole is flat, roomy and uncluttered, serving racer and cruiser alike. Much of the furniture is built outside the hull and installed before the deck is set.
Class Rules and Racing Format
The 45 races as a level boat, with weight equalized through lead correctors, and the class rules were drawn by Mike Urwin of RORC with Carole Abbot as secretary. Racing is strictly owner driven, permitting only a limited number of professional sailors and a limited stock of new sails per season, the aim being close and exciting competition. At each class event a dedicated PRO runs multiple windward-leeward races on dedicated courses, and the class maintains a long relationship with the RORC rating office administering the Swandicap system. An innovative bulb-access design allows up to 400 kg to be added or removed for IMS racing.
Known Issues and Refits
Two new 45s snapped their rudders during the Swan Cup in Sardinia, the carbon rudder stocks failed when the boats wiped out downwind at over 20 knots. The broken parts were analyzed at Nautor's test facility at VTT Helsinki, a government-backed Finnish technical centre, and the new stocks remain carbon but built to a much higher specification from that analysis. The only other modification since launch has been an upgraded mainsheet traveller system. A period tester noted the lack of a foot brace on the sole each side of the helm when heeled hard under spinnaker.
The Verdict
The Swan 45 is a deliberate fusion of Swan cruising comfort and one-design race discipline, engineered so that owner-drivers can compete closely without an open chequebook. Her construction pairs a cored deck with a solid reinforced bottom, and her rigging details keep the crew off the foredeck and the helmsman in command. The rudder-stock episode was addressed at the production level rather than left as a owner risk.
Pros
- Owner-driven one-design format with cost controls and level-class correctors
- Carbon-mast Frers hull with swept spreaders and no running backstays
- Teak-decked, satin-finished interior with three layout choices
Cons
- Early hulls susceptible to carbon rudder-stock failure downwind until upgrade
- No foot brace at the helm sole when pressed hard under sail
- Open transom standard, requiring added closure for cruising security
