This modern, wide-beam cruiser combines generous accommodation with the lively feel testers noted on the water. Its uncluttered decks, flexible interior layouts, and useful cockpit features also reflect a clear emphasis on practical cruising.
Design and Construction
The 412 measures 12.70 metres overall, with an 11.15-metre waterline, a 4.20-metre beam, and a 2.10-metre draft. Light displacement is 8,940 kg, including 2,600 kg of iron ballast.
Felci’s hull is voluminous, with interior volume, circulation space, and headroom managed to provide excellent liveability. The 412 was offered in three versions—Comfort, Liberty, and Adventure—which differed in equipment and interior layout rather than hull design. All used the 410 GL’s proven shape, taking advantage of the same voluminous and fast hull.
Barche Magazine found the side decks completely uncluttered and the route to the bow easy to negotiate. There is no diagonal reinforcing bar at head level to obstruct movement. The upper shrouds attach to the side wall and the lower shrouds to the deckhouse, keeping the side decks clear and contributing to the practical deck layout the magazine praised.
Rig and Handling
The 412 carries a fractional sloop rig with 71 square metres of sail area: a 38-square-metre mainsail and a 33-square-metre genoa. The standard 105 percent genoa is a working jib rather than a Code Zero. However, the stemhead fitting accepts a second furler for a Code 0, broadening the boat’s light-air range.
Vela & Motore found that the hull responded well and maintained good speed in less than 10 knots of wind. Rolling out a Code 0 improved matters further, providing an almost all-round light-air sail. A fixed delfiniera replaces the 410’s retractable bowsprit, simplifying the bow while supporting downwind sail options.
The boat has a single long, narrow, neutral spade rudder. Two well-spaced aluminium wheels give the helms good sightlines to the sails. Four winches are fitted: two within reach of the wheels and two near the companionway. A winch in front of each wheel handles both mainsail trim and bow gear.
Performance Under Sail and Power
Barche’s testers recorded nearly seven knots close-hauled, seven and a half knots with the sails eased, and eight knots when they were eased further. The low-drag hull and responsive helm give the 412 a turn of speed that belies its cruising accommodation.
A Volvo Penta D2-55F, rated at 41 kW (55 hp) and coupled to a saildrive, drives the boat at 7 knots cruising and 8 at top speed.
Rather than a conventional bow propeller, the test boat had Holland Marine jet thrusters with four nozzles—two forward and two aft—eliminating bow-mounted propellers entirely.
Cockpit and Deck Equipment
The cockpit is spacious enough for crew to move around without colliding. When not in use, the table folds away into the bench seating. It includes a central foldaway light, while a stern-mounted 12-inch Garmin plotter is paired with a Panoptix Forward transducer.
An outdoor galley at the stern includes a barbecue grill, sink, and chopping board. It is stored beneath lockers that also serve as helmsman seating. This arrangement adds open-air cooking and entertaining space without obstructing movement around the cockpit.
Accommodation
Below, the 412 has 194 cm of standing headroom through the cabins and saloon. Windows and portholes bring in abundant natural light.
Three interior layouts were catalogued:
- Three cabins and two heads, as tested
- Three cabins and one head, the standard arrangement
- Two cabins and two heads
According to the trial report, the three-cabin, two-head layout slightly penalizes the forward owner’s cabin. Even so, the overall interior makes effective use of the hull’s volume and provides genuine liveability. A wine cellar beneath the cabin sole, immediately at the foot of the companionway steps, is a signature Grand Large feature.
The Verdict
The Dufour 412 Grand Large is a modern cruiser that retains the 410’s fast, voluminous hull while improving the practicality of the deck and bow. It is quick under sail and power, thoughtfully arranged on deck, and bright and roomy below. Its range of layouts suits both private owners and charter use.
The absence of a conventional bow thruster in favour of the jet units fitted to the test boat is unusual but tidy. Buyers seeking the best light-air performance, meanwhile, will want the second furler and Code 0 rather than relying solely on the standard working jib.
Pros
- Voluminous Felci hull with strong light-air performance and easy seven-to-eight-knot speeds
- Clear, uncluttered side decks and easy access to the bow
- 194 cm of headroom and excellent natural light below
- Three equipment versions and flexible accommodation layouts, with up to three cabins and two heads
- Practical folding cockpit table and outdoor galley at the stern
Cons
- Three-cabin, two-head layout slightly compromises the forward owner’s cabin
- The jet-thruster system replaces the familiar bow propeller and introduces a different maintenance item
- The standard genoa is a working jib rather than a Code Zero, limiting light-air punch without the optional furler
