Dufour 455 Grand Large Sailboats for Sale

Layouts on the Used Market

The 455 was offered in two distinct interior arrangements, and both appear on the brokerage market, though the three-cabin version is the more commonly encountered. In that layout, a proper island-berth master stateroom occupies the bow, served by a private head with a separate stall shower — a genuine stateroom rather than a curtained-off forepeak. Two aft cabins flank a central technical space housing the engine, batteries, and mechanical gear, each with its own berth wide enough for comfortable sleeping and enough headroom to dress without contortion. The four-cabin variant sacrifices the forward stateroom's generous proportions to carve out an additional sleeping cabin, which suits charter-oriented owners or families who need the extra berth count more than they need the queen-size bow cabin. The longitudinal galley runs to port in both layouts, paired with a nav station and a large U-shaped saloon settee to starboard — a classic arrangement that works well offshore because the cook has a counter to brace against and the navigator sits within easy conversation range of the cockpit.

Equipment and Common Upgrades

Used examples of the 455 are almost universally well equipped, reflecting the boat's role as a passage-making cruiser whose owners tend to invest in it seriously. A bimini, autopilot, chartplotter, radar, and electric winches are commonly fitted across the market; the electric Harken primaries that were factory options on early boats have become a near-universal feature. Furling mainsails — whether factory in-mast or owner-added on-boom systems — appear frequently, driven by the demands of shorthanded sailing. Heating systems are widely fitted, as the 455 attracts owners who use the boat year-round in northern European waters. A life raft in a dedicated cockpit locker is standard fare, and spinnaker equipment, including asymmetric kites and code-zero furlers, is a frequent owner upgrade on boats that have done offshore miles. Teak cockpit and side-deck overlays appear on a meaningful share of listings, most installed as factory options during the Arpège Limited Edition production runs.

Bow thrusters, AIS transponders, and cockpit showers appear on many boats without being universal. Owner-fitted watermakers, solar panels, freezer upgrades, dinghy davits, and hot-water calorifiers represent the next tier of customization — these additions signal a boat that has been seriously prepared for extended cruising and typically indicate a higher level of overall maintenance attention as well. A few boats carry the optional generator installed in the forward anchor-locker area, which adds meaningful comfort for liveaboard use but requires attention to sound insulation and ventilation.

What to Inspect

The 455's construction is generally sound, and the NPG gelcoat backed by NPG resin in the skincoat offers good osmotic resistance, but older hulls should be surveyed carefully for blister formation below the waterline — any boat that has spent extended time in warm water warrants particular scrutiny here. The hull is hand-laminated GRP with a moulded inner grid structure glassed to the hull for stiffness; inspect the grid-to-hull bonding at the tabbing joints, particularly amidships where flexing can cause delamination over time.

The deck-stepped mast transfers its loads through a single chainplate on each side to a tierod running to a longitudinal girder behind the saloon furniture. This single-chainplate arrangement for cap shrouds and aft lower shrouds means the load path is concentrated; have a rigger inspect the chainplate backing plates, the tierod attachment points, and the hull girder for any signs of cracking or movement, especially on boats that have raced or seen heavy offshore use. The 15/16ths fractional rig with continuous standing rigging should be checked for wire fatigue at the swages and for toggle wear at the chainplates.

The Volvo Penta saildrive installation is reliable in service but requires diligent attention to the saildrive seal — the standard engine is a Volvo diesel with saildrive drive, and the flexible bellows seal between the leg and the hull is a wear item that should be inspected and replaced on a regular schedule; a failed seal can sink the boat at the dock. Confirm that the saildrive leg zincs are current and that the leg itself shows no electrolytic damage. The companionway steps lift on gas struts to access the engine; check that the struts still hold and that the engine bay shows no signs of exhaust or coolant leaks.

The miniature bilge sump noted in early reviews is a legitimate concern: the sump is small by offshore standards, and on boats that have developed any slow leaks — shaft seal, port frames, deck hardware — it can overflow before an alarm triggers. Inspect the bilge area carefully and ask about pump-out frequency. The balsa-cored decks were built by infusion process and are generally well executed, but any deck hardware that has been added or repositioned by owners should be examined for proper backing plates and bedding; water intrusion into balsa core around stanchion bases, chainplates, and poorly rebedded ports is a common finding on boats of this era.

Below, inspect the Moabi joinery for delamination at the glued joints — the wood looks beautiful but requires stable humidity to stay tight. Check the galley's top-loading refrigeration: the compressor is a common replacement item, and the insulation quality in older boxes can degrade. The manual toilets in both heads are straightforward but high-cycle components; electric conversions are a common owner upgrade, and boats that have been converted should have the through-hull and hose installations inspected for age and condition.

Availability and Buyer's Takeaway

The 455 Grand Large is widely available across the Mediterranean, with France, Italy, and Turkey all carrying healthy brokerage inventory. Northern European markets — Sweden, Ireland, and the broader Atlantic coast — account for a further share of listings, and the boat appears occasionally in Pacific and Australasian waters. North American inventory is thinner but not absent, reflecting the boat's stronger following in European cruising grounds.

The 455 punches above its size in livability, sails better than its volume would suggest, and rewards owners who use it for what it was designed to do: extended coastal and bluewater cruising with a small crew. For a buyer prepared to invest in a thorough survey and address any deferred maintenance items, it represents a well-thought-out cruising platform with a strong parts-and-service network through Volvo, Harken, and Raymarine.

Pre-purchase checklist:

• Commission a full out-of-water survey with osmosis testing on the hull below the waterline
• Inspect the saildrive bellows seal and arrange replacement if age or condition is uncertain
• Have a rigger examine the single chainplates, tierod attachment points, and all swaged terminals in the standing rigging
• Probe all deck hardware penetrations and stanchion bases for balsa-core moisture
• Test both electric winches and the windlass under load
• Run the engine under load and check the exhaust for smoke, coolant for contamination, and the bilge for oil or water intrusion
• Confirm the life raft certification is current and that the dedicated locker drain is clear
• Verify the inventory: sails (age and condition of main and genoa), autopilot function, chartplotter and radar installation dates, and any installed watermaker or generator service records
