Design and Construction
At 15.25 meters overall with a 5.05-meter beam and a displacement of 14 tons, the Atoll 50 was a beamy, heavy platform whose volume was the entire point. The deck is solid fiberglass. The defining exterior gesture is the hard top with an integrated sunroof, which Briand used to turn the cockpit into a sea-view saloon rather than a weather-exposed working area. In the bow, a recessed sunbathing space was cut into the deck — a solution absent on the smaller 43-foot Atoll — trading interior headroom in the two forward cabins for lounging comfort on deck. The hard top was not a styling exercise; it allowed comfortable sailing even bad weather by keeping the helm and social space protected anchor.
Rig and Handling
All maneuvering was deferred to the cockpit, consolidating control of the 117 square meters of sail area into the protected helm area aft. With a single 85-horsepower diesel and a 132-gallon fuel capacity, the boat was built to motor reliably between charter ports as much as to sail, and the 396 gallons of water capacity underscored the hospitality-first brief.
Accommodations
The interior configuration included as many as six double cabins with a total of 12 beds and four bathrooms with showers — a density that explains the boat's charter-only identity. The cockpit itself functioned as a saloon with an ocean view, fitted with a galley in the catamaran manner, a living area, and a double L-shaped sofa with dedicated coffee tables, blurring the line between interior and exterior social spaces. The two aft cabins and two separate toilets were reached from the deck via ladders, and a compact forward compartment served the other two heads and forward cabins. The recessed bow sunbathing space reduced the height of those forward cabins, a compromise accepted in pursuit of deck-level comfort.
The Verdict
The Dufour Atoll 50 is a curiosity: a Briand-styled, charter-born voluminous platform whose hard-top cockpit and six-cabin layout made it a capable bareboat host, but whose two-year production and 30-unit run left it a rare sight. It rewards buyers who value protected social space and berth count over traditional cruising intimacy, and punishes those who expect a private-owner pedigree.
Pros
- Hard top with sunroof allowed comfortable sailing in bad weather
- Cockpit functions as a sea-view saloon with galley and L-shaped seating
- Six double cabins and four bathrooms support 12 guests
Cons
- Designed exclusively for chartering, not private ownership
- Recessed bow sunbathing space reduces forward-cabin headroom
- Only 30 built; brief production limits spares and owner familiarity
