2016–present · designed by Umberto Felci (hull); Dufour in-house (interior) · built by Dufour Yachts
Modern mid-large Dufour cruiser in the Grand Large cruising-spec line. Twin-rudder, hard-chine hull, modular interior in 2-, 3-, or 4-cabin configurations. Reflects the contemporary French production cruiser design language (close architectural cousins: Beneteau Oceanis 41/45, Jeanneau Sun Odyssey 410/440). Aimed at coastal / Mediterranean / Caribbean cruising and charter use, with twin-helm cockpit, walk-through transom, swim platform.
Check this first — charter-spec three- and four-cabin against owner-spec two-cabin. More cabins means less of everything else: stowage and tankage are divided up rather than added, so the same hull supports more bunks and less self-sufficiency. And the layout is a clue to the boat's history — an ex-charter hull has usually done more hours, under more different hands, with maintenance done to a fleet schedule rather than an owner's. That is not disqualifying and charter boats are often mechanically well kept, but it should change what the survey looks hardest at and what you expect the interior to have taken.
This is a general read on the Dufour 412 Grand Large 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 listing, run a free FairKeel report on that boat.
Opened specs show a single spade rudder with twin helm wheels. Inspect rudder bearings, stock, quadrant/linkage, stops, and grounding repair history rather than assuming two rudder assemblies.
Opened specs list a 40hp diesel but do not conclusively verify the exact saildrive model. Confirm engine variant, drive type, boot/seal service history, lower-unit oil, and anodes by hull documentation.
Heavy Mediterranean / Caribbean charter uptake. Verify hours per year. Wear in cushions, winches, head fittings, deck hardware. Owner-spec hulls command price premium.
Deck-stepped mast on 5-10 year-old hulls. Original rig within typical service interval but charter-fleet wear patterns (chafe, cotter pin loss, end-fitting corrosion) may show up earlier.
Modern factory electrical packages but charter-spec hulls often have minimal house bank. Liveaboard requires bank upgrade and sometimes lithium conversion.
This guide is the class. A report is that hull. Paste the listing you're looking at and FairKeel grades every claim in it against what's known about the Dufour 412 Grand Large — where the evidence is thin, the red flags worth a second look, the costs likely to land in your first season, and whether the boat suits the plans you describe in a few short questions.
It won't read the photos or put a number on the boat — that's the $249 Deep-Dive, and for the real answer, a surveyor. It will tell you when a Deep-Dive isn't worth buying. Free, no account, usually a minute or two.
