Dufour 405 Grand Large Buyer's Guide
The Dufour 405 Grand Large is a Felci-Roséo-designed Grand Large cruiser, a 40-foot performance cruiser with a solid hand-laid hull and a balsa-cored deck. On the used market it presents as a versatile three-cabin-or-fewer coastal and bluewater candidate, and understanding its layout options, common equipment, and a few structural points will sharpen any purchase decision.
Layouts on the Used Market
Owner three-cabin layouts are the more common on used Dufour 405 Grand Large yachts, but both the one- and two-aft-cabin versions are available, and ex-charter examples are common. The one-aft-cabin arrangement gives an L-shaped galley aft and a chart table between saloon seats, plus a vast cockpit locker that can double as a small workshop. Where a buyer chooses two aft cabins, the boat is fitted with a linear galley and its own separate nav station facing forward with a chart table and seat anchor. All layouts share a large forward owner's cabin with ensuite head, a second head aft of the saloon, and 6-foot-5 headroom dropping to 6-foot-2 forward. A third inspected layout placed the galley aft to starboard behind a twin-chair nav station with a second double cabin aft to port and a storage cabin reachable from the cockpit locker.
Equipment and Common Upgrades
Most used 405s carry a strong baseline of cruising gear. Commonly fitted items include autopilot, chartplotter, solar, bimini, liferaft, swim platform, bow thruster, inverter, heating, dodger, AIS, cockpit shower, and hot water — a suite that means a buyer can step aboard and cruise without immediate expense. Often-seen additions are air conditioning, radar, teak decks, spinnaker, furling main, and EPIRB. Less common owner upgrades include electric winches, a short-handed sail-handling setup, lithium batteries, watermaker, gennaker, freezer, and dinghy davits. For buyer consequence, the power-and-energy cluster (solar, inverter, optional 2.5kW generator, lithium upgrades) determines off-grid autonomy; canvas and sail-handling (bimini, dodger, furling main, spinnaker) shape daily comfort; navigation (chartplotter, AIS, radar) is mostly factory or early refit; and comfort (heating, air conditioning, hot water) defines liveaboard appeal.
What to Inspect
The structural record shows the hull is solid hand-laid fiberglass with NPG gelcoat and resin for osmosis protection, and a separate internal grid laminated to the hull anchor. The deck is a balsa-cored infused polyester sandwich, so survey the deck for softness or moisture intrusion at penetrations. The cast-iron keel bolts to a stainless-steel backing plate and the semi-elliptical rudder hangs off a solid stainless post — check keel-bolt torque marks and rudder post play anchor. Twaron-reinforced stringers and frames carry rig loads to the keel; inspect chainplate tie-rods and deck termination for corrosion. Water and fuel tanks sit under the berths, and a panel above one berth accesses batteries and the optional generator anchor.
Availability and Buyer's Takeaway
These yachts typically appear in Greece, Saint Martin (French part), the United Kingdom, France, Portugal, and New Zealand. For a shopper, the checklist is brief: confirm layout (three-cabin most common, ex-charter frequent), verify deck-core integrity and keel/rudder attachment, confirm the Volvo 40hp baseline or optional 55hp, and review the commonly fitted cruising suite before budgeting upgrades. A clean-surveyed 405 with the two-aft-cabin plan and Raymarine helm instruments remains a sensible used performance-cruiser purchase.
