The boat carries CE Class A (Ocean) certification, the European Union designation for extended voyages. At 41 feet overall, with a 13-foot beam and a displacement of nearly 17,790 pounds, it sits at the upper end of the comfortable cruiser class of its era.

Design and Construction

The hull and deck are fiberglass. The hull uses sandwich construction, while the deck is solid fiberglass. Interior joinery is mahogany, a wood found in many contemporary boats but fitted here to a cruising standard rather than a bare charter specification.

The Dufour 41 Classic has a length-to-beam ratio of 3.00 and a ballast ratio of 33 percent. Its bulb keel carries 5,620 pounds of ballast, and its displacement-to-length ratio is about 212. Together, those figures describe a beamy, moderately loaded cruiser. The boat has a spade rudder and a masthead sloop rig, with a waterline length of 32.67 feet.

Dufour offered the 41 Classic with different keel alternatives, both lead-cast fin keels. Depending on load, the deeper version draws about 6.56 to 6.86 feet, limiting the boat to major marinas. The shoal option draws 4.92 to 5.22 feet and can enter most harbours. That choice significantly affects where an owner can cruise comfortably without worrying about grounding in the approach.

Rig and Handling

The masthead rig carries 882 square feet of sail, producing a sail-area-to-displacement ratio of 21.76. That’s enough sail to keep the boat moving without demanding a large crew.

The specified sheet dimensions are practical rather than exotic:

  • Jib and genoa sheets: 39.2 feet long and 14 mm in diameter
  • Mainsheet: 98 feet long and 14 mm in diameter
  • Spinnaker sheets: 86.3 feet long

The underbody has about 484 square feet of wetted surface. Its immersion rate is about 265 kg per centimetre, or 1,485 pounds per inch, so the boat settles predictably as crew and stores come aboard.

Design records give a theoretical maximum displacement-hull speed of 7.7 knots. Calculated motoring speeds are about 5.6 knots with a Volvo Penta MD2030 and roughly 7.4 knots with a 50 hp Volvo Penta.

The capsize screening value is 2.05, which would bar the boat from organized ocean races. Its Class A (Ocean) certification, however, confirms that it was built for extended offshore use rather than organized ocean racing.

Accommodations

Below, the Dufour 41 Classic has three cabins and berths for six plus two. The layout suits a family or two cruising couples without resorting to the cramped quarter-berth compromises common in smaller designs.

Standard accommodations include a proper galley and a toilet facility, with mahogany joinery throughout. This is a genuine cruising interior rather than a bare charter layout.

The motion comfort ratio is 23.9. That comparatively lively figure suggests a boat that moves with the sea rather than absorbing it like a heavier full-keel cruiser. It may be pleasant underway, but it isn’t a pillow-soft passagemaker.

Engines, Tankage, and Ownership

Buyers considering a used example should note that different engines were offered during the production run. Both the Volvo Penta MD2030 and a 50 hp Volvo Penta appear in the record, and the higher-output installation materially changes the calculated motoring speed.

Standard tankage consists of 49 gallons of diesel and 97 gallons of water. Those capacities reflect the boat’s coastal and offshore cruising brief rather than a tanker’s range. The CE Class A certification provides a useful reference point for offshore ambitions, but the capsize screening value reinforces that this is a cruiser first.

The Verdict

The Dufour 41 Classic is a well-proportioned, beamy cruiser from the mid-1990s, designed by J&J Design and Olivier Poncin and built by Dufour Yachts S.A. to the CE Class A (Ocean) standard. Its two lead fin-keel options allow owners to trade draft for harbour access, while the masthead rig and modest sail-area-to-displacement ratio keep handling manageable.

Below, the three-cabin, six-plus-two-berth mahogany interior provides a genuine cruising layout rather than a charter compromise. The motion comfort ratio, however, is a reminder that this is a modern fin-keel hull rather than a traditional heavy cruiser.

Pros

  • CE Class A (Ocean) certification for extended voyages
  • Choice of lead fin keels: shoal draft of 4.92–5.22 ft or deeper draft of 6.56–6.86 ft
  • Three cabins, six-plus-two berths, mahogany interior, proper galley, and head
  • Masthead rig with an SA/D of 21.76 and manageable sheet sizes for short-handed crews

Cons

  • Capsize screening value of 2.05 excludes the boat from organized ocean races
  • Motion comfort ratio of 23.9 indicates a livelier ride than a heavy full-keel cruiser
  • Standard fuel capacity of 49 gallons limits unrefuelled motoring range
