Dufour F39 Information, Review, Specs

Sailing Performance & Handling

The influence of German Frers is most evident in the F39’s hull form, which features a fine entry and a powerful, well-balanced stern. While many cruisers of this era suffered from heavy weather helm when pressed, the F39 is noted for its exceptional tracking and balance. With a Sail Area/Displacement ratio typically hovering around 19.5, the boat is remarkably responsive in light air—a trait often missing in its contemporaries like the heavier Beneteaus or Pearsons of the same vintage.

The boat was typically delivered with a deep fin keel (approximately 6'3" to 6'11" depending on the specific regional market version), which provides excellent lift and a high ballast-to-displacement ratio of nearly 40%. This makes the F39 a "stiff" boat that can carry its canvas well into the upper teens before a first reef is required. Owners often report that the boat feels "locked in" when sailing upwind, requiring only a light touch on the large-diameter destroyer wheel. The masthead sloop rig is simple and robust, though the large genoa does require significant winching effort, a common characteristic of 1980s sail plans.

Interior Comfort & Variations

Internally, the F39 reflects the high-end craftsmanship of the "Prestige" era of Dufour. The layout was typically offered in two primary configurations: a two-cabin "owner’s" version and a three-cabin layout intended for larger groups or charter. In the two-cabin version, the aft cabin is remarkably spacious for a 39-footer, featuring a large transverse berth and ample standing room. The woodwork is generally high-quality teak or mahogany, finished with a durability that has allowed many examples to retain their luster decades later.

The main salon utilizes a traditional arrangement with a U-shaped settee to port and a straight settee to starboard, providing seating for six around a central folding table. A notable feature of the German Frers influence is the ergonomic focus on the navigation station and galley. The galley is L-shaped and positioned at the base of the companionway, designed to be secure while under sail. Headroom is generous, clearing 6'3" in the main cabin, which helps the interior feel larger than its 12'6" beam might suggest.

Sibling Models & Evolution

The F39 was part of a broader "Frers-designed" family that revitalized the Dufour brand during the late 80s. Its most direct sibling is the Dufour 42, which shares nearly identical styling and hull dynamics but offers more volume for a three-cabin, two-head arrangement. On the smaller end of the spectrum, the Dufour 35 Classic followed later, taking some stylistic cues from the Frers era but moving toward a more modern, high-volume hull. The F39 specifically was succeeded by the Dufour 38 and 39 models of the 1990s, though many purists argue that the Frers-designed F39 remains the superior sailing machine due to its narrower beam and more traditional underwater profile.

Known Issues & Buyer’s Checklist

Prospective buyers of a Dufour F39 should focus their inspections on the following high-signal areas:

• Grid Structure & Keel Bolts: Like many performance cruisers of this era, the F39 utilizes an internal fiberglass grid (liner) bonded to the hull. It is vital to inspect the bilge for any "crazing" or separation of the grid near the keel floors, which can indicate a previous hard grounding.
• Deck Core Integrity: While the hulls are solid fiberglass, the decks are balsa-cored. High-moisture readings are common around the stanchion bases and the windlass mounting point. If the deck feels "spongy" underfoot in these areas, a core replacement may be necessary.
• Rudder Bearings: The spade rudder is known for its responsiveness, but the bearings can wear, leading to a "thumping" sensation or play in the wheel.
• Osmotic Blistering: While Dufour used high-quality resins, boats from the mid-80s are still susceptible to osmosis. A thorough hull survey is recommended to check for historical blister repairs or current saturation.

Community & Resources

Owners of the F39 are supported by a strong network of brand enthusiasts. The Association des Propriétaires de Dufour (Dufour Owners Association) is the primary technical resource, offering historical brochures and rigging diagrams that are essential for maintaining the Frers-era boats. While headquartered in France, the association has a broad international reach.

The Verdict

The Dufour F39 is a "sailor’s cruiser," offering a level of sophistication and performance that rivals more expensive yachts from Swan or Baltic of the same era. It is ideally suited for a couple or small family that prioritizes sailing qualities over maximum interior volume.

Pros:

• Exceptional Pedigree: Designed by German Frers, ensuring timeless lines and balanced handling.
• Sailing Dynamics: Excellent upwind performance and stiffness in heavy weather.
• Build Quality: Superior interior joinery compared to later mass-production models.

Cons:

• Maintenance Needs: As a boat approaching 40 years of age, systems like standing rigging and balsa cores often require significant updates.
• Cockpit Layout: The cockpit is optimized for sailing rather than "lounging," which some modern cruisers may find cramped.
• Deep Draft: The performance-oriented keel may limit access to shallow cruising grounds like the Bahamas or parts of the Chesapeake Bay.
