Dufour T6 Information, Review, Specs

Sailing Performance & Handling

The sailing characteristics of the Dufour T6 are defined by its light displacement and its fractional rig, which was somewhat modern for a production trailer-sailer of its era. With a displacement of approximately 850kg (1,874 lbs) and a generous sail plan, the boat is remarkably responsive in light to moderate airs. The swing-keel design provides a draft that ranges from a mere 0.30m (about 1 foot) with the board up to 1.30m (4.3 feet) when fully deployed.

Under sail, the T6 displays the typical agility of a 20-foot hull, though its relatively narrow beam compared to modern wide-stern designs means it requires active weight management from the crew to stay flat in gusts. Handling is generally described as "nervous" but predictable—a trait often associated with Michel Dufour’s hull shapes. While it lacks the offshore "sea-kindliness" of the larger Dufour 28 or 31, the T6 tracks reasonably well for a swing-keel boat, provided the centerboard pivot is well-maintained to prevent "clunking" or vibration. The boat's performance is at its best on a reach, where its light weight allows it to accelerate quickly, though its upwind ability is naturally limited by the lack of a deep, heavy bulb keel.

Interior Comfort & Variations

Despite its modest 6.15-meter length, the T6 features a surprisingly functional enclosed cabin, adhering to the "four-berth" standard of the 1970s trailer-sailer era. The layout is centered around a V-berth in the bow and two narrow quarter-berths that extend aft under the cockpit seats. Because the centerboard trunk occupies a significant portion of the midships area, the interior can feel somewhat bisected, a common trade-off in boats of this size and type.

Headroom is limited—typical for a 20-foot boat—requiring most adults to remain seated or hunched while below deck. However, the use of molded fiberglass liners and basic wood trim gives the cabin a clean, durable feel. Variations were minimal throughout its production run, though some units featured a simplified galley block with a single-burner stove and a small manual water pump. Its primary sibling, the Dufour T7, is significantly more radical, featuring a twin-cockpit design and an aft cabin, making the T6 the more traditional and easier-to-maintain option of the two.

Known Issues & Buyer’s Checklist

Prospective buyers of a Dufour T6 should prioritize the inspection of the swing-keel mechanism and the structural integrity of the hull-deck joint.

• Swing-Keel Pivot and Cable: The pivot bolt and the lifting cable are the most critical mechanical points. If the bolt is worn, the keel will wobble, potentially damaging the trunk. Inspect for any signs of weeping around the pivot pin area.
• Deck Compression: Like many boats of this vintage, the mast step area can suffer from core compression. Check for hairline cracks or a slight depression in the deck where the mast sits, which often indicates that the internal support or the deck core has softened.
• Rudder Assembly: The T6 uses a transom-hung rudder which is subject to significant stress. Check the gudgeons and pintles for play; excessive movement here can lead to a loss of steering feel or, in extreme cases, failure of the mounts.
• Osmosis: While Dufour hulls from this period are generally robust, the T6 was built during an era when fiberglass resins were susceptible to osmotic blistering. A moisture meter test on the hull below the waterline is recommended, especially if the boat has been kept in the water rather than on a trailer.

Community & Resources

Owners of the T6 benefit from the broader Dufour community, which remains one of the most active in Europe. The Cercle des Propriétaires de Dufour in France is the primary repository for technical drawings and historical brochures for the "T" range. In the United Kingdom, the Dufour Association provides a platform for owners to share maintenance tips, specifically regarding the sourcing of replacement parts for older models that are no longer supported by the modern factory.

The Verdict

The Dufour T6 is a classic example of late-70s French naval architecture, offering a balanced mix of performance and portability. While it lacks the interior volume of modern 20-footers, its pedigree and build quality make it a rewarding project for the coastal day-sailer.

Pros:

• High Portability: Light enough to be towed by a standard vehicle and easily launched from a trailer.
• Versatile Draft: The 0.30m minimum draft allows for beaching and exploring shallow estuaries.
• Strong Pedigree: Designed by Michel Dufour, ensuring better-than-average sailing dynamics for a trailerable boat.

Cons:

• Confined Interior: The centerboard trunk significantly encroaches on the living space.
• Age-Related Maintenance: Potential issues with keel mechanisms and deck compression require careful vetting.
• Limited Headroom: Not suitable for extended live-aboard cruising or tall sailors.
