Dufour 35 Information, Review, Specs

Sailing Performance & Handling

The Dufour 35 is a heavy-displacement cruiser characterized by its stiff, powerful motion in a seaway. With a displacement of approximately 13,000 pounds and a high ballast-to-displacement ratio (roughly 40%), the boat is exceptionally stable. Unlike modern light-displacement cruisers that "skate" over the water, the 35's IOR-influenced hull—featuring a deep forefoot and a significant beam carried well aft—cuts through chop with minimal loss of momentum.

Under sail, the boat is known for its balance, though it does exhibit the typical IOR tendency to "broach-roll" if pushed too hard under a massive symmetric spinnaker in a following sea. In a blow, however, the 35 is in its element. According to owner anecdotes and historical performance data, the boat tracks exceptionally well thanks to its deep skeg-hung rudder, providing a sense of security when hand-steering in heavy air. While it lacks the light-wind agility of its smaller sibling, the Safari 27, the 35’s ability to carry sail late into a building breeze makes it a preferred choice for North Sea and Atlantic crossings.

Interior Comfort & Variations

For a 35-foot vessel designed in the early 1970s, the interior volume was considered revolutionary. Michel Dufour utilized the boat’s nearly 12-foot beam to create an accommodation plan that could sleep up to eight people, though a crew of four is far more realistic for modern standards. The layout typically features a large V-berth forward, followed by a full-width head compartment. The main salon is defined by a massive U-shaped dinette to port, which can be converted into a double berth, and a straight settee to starboard.

Materials used during this era were high-quality, involving extensive use of solid mahogany or teak and robust marine-grade plywood. One of the most distinctive features is the dedicated navigation station, which is unusually large for a boat of this size, reflecting the offshore racing pedigree of the design. While the "Classic 35" released in the mid-1990s—a separate design by J&J—offered a more modern, lighter interior with an aft cabin, the original 1970s Dufour 35 is celebrated for its sea-berths and secure, "enclosed" feel that sailors prefer for long-distance voyaging.

Known Issues & Buyer’s Checklist

Prospective buyers of a Dufour 35 should focus their inspections on the era's common fiberglass and mechanical challenges:

• Osmotic Blistering: Like many boats built in the 1970s before the widespread use of vinylester resins, the Dufour 35 is prone to hull blistering. While rarely structural on these thick, solid-laminate hulls, it is a significant maintenance item.
• Original Engines: Many units were originally fitted with Volvo Penta MD2B or MD11C engines. Parts for these vintage "green monsters" are becoming increasingly scarce and expensive; many savvy buyers prioritize hulls that have already undergone a repower with a modern Yanmar or Beta Marine diesel.
• Chainplates and Rigging: The chainplates on the 35 are robust, but the sealant around the deck penetrations often fails over decades, leading to moisture ingress in the bulkheads. Any signs of "tea staining" or soft wood near the shroud attachments should be viewed with caution.
• Rudder Bearings: The skeg-hung rudder is a strength, but the bronze or nylon bushings at the base of the skeg can wear down, leading to a "knocking" sensation in the steering.

Community & Resources

The Dufour 35 benefits from a dedicated following, particularly in France and the United Kingdom. The Dufour Association, based in the UK, serves as a primary technical repository for owners of the 35, providing access to original manuals and specific advice on retrofitting the 1970s hardware. In France, the Cercle des Propriétaires de Dufour offers a similar community for Francophone owners, focusing on rallies and historical preservation.

The Verdict

The Dufour 35 is a "sailor’s sailboat," built for those who value structural integrity and heavy-weather capability over modern dockside amenities. It represents a bygone era of French boatbuilding where hulls were hand-laid with an abundance of resin and glass.

Pros:

• Exceptional Seaworthiness: A heavy, stable hull that feels secure in gale conditions.
• Build Quality: Solid fiberglass construction without the use of problematic core materials in the hull.
• Classic Aesthetics: The iconic 1970s Dufour lines remain attractive and distinctive in any marina.

Cons:

• Age-Related Maintenance: Buyers must be prepared to tackle vintage plumbing, wiring, and potential osmosis.
• Maneuverability: Like many long-keeled or skeg-rudder designs of the era, it can be a handful to reverse into a tight slip.
• Light Air Performance: The heavy displacement makes it sluggish in winds under 8 knots compared to modern performance cruisers.
