Dufour 485 Grand Large Buyer's Guide
The Dufour 485 Grand Large is a 48-foot Grand Large cruiser from Dufour Yachts, designed by Umberto Felci with Patrick Roséo, and built from 2006 onward. On the brokerage market she appears mostly as owner three-cabin layouts, though both owner and charter-derived versions turn up, with ex-charter boats a common sight. A buyer should treat her as a volume-oriented ocean cruiser with a slightly overrigged fractional rig and a sandwich hull.
Layouts on the Used Market
Owner three-cabin arrangements predominate among used 485s, but the boat is not exclusive to that plan and both layout types are obtainable. Ex-charter examples are common, which means a prospective owner should expect higher cycle counts on winches, rigging, and through-hulls than a privately kept boat would show. The 15.4-foot beam and 156-gallon water capacity signal a boat built for living aboard during long passages rather than coastal sprints.
Equipment and Common Upgrades
Well-found examples commonly carry an inverter, autopilot, chartplotter, AIS, radar, life raft, freezer, watermaker, air conditioning, bow thruster, electric winches, and teak decks, with bimini and hot water also usual. That cluster means a buyer gets turnkey power management, self-steering, and tropical-comfort kit without immediate uplift cost. Often-seen additions include heating, a spinnaker, and a dodger, while solar, a gennaker, and a cockpit shower appear as occasional owner upgrades rather than standard fit. The bow thruster and electric winches are the items with real handling consequence on a 27,000-pound yacht in tight marinas.
What to Inspect
The hull is a sandwich construction, so a buyer should sound for core delamination or moisture ingress rather than assume solid-laminate behavior. At least one bulb-keel option uses an iron keel, and that casting should be checked for galvanic corrosion, coating failure, or stray-current pitting where it meets the hull flange. Confirm the actual draft by measuring against load, because the two fin-with-bulb options differ by over a foot and the deeper one restricts harbor entry draft is about 2.25 - 2.35 meter dependent on the load. Verify the CE Class A plate is present and matches the hull, since that ocean rating is a core resale point.
Availability and Buyer's Takeaway
These yachts are typically found in Italy, Belgium, Gibraltar, France, Spain, and Martinique. Before committing, a shopper should:
- Confirm the layout is owner or ex-charter and inspect wear accordingly
- Sound the sandwich hull for core moisture
- Check the iron keel for corrosion at the joint
- Measure loaded draft against the keel option
- Verify the CE Class A certification plate
