Rare Monomaran Design | Catamaran-Like Living Space | Single-Level Layout | Upgraded Electrical Systems | Established Rental Income
This 50' Dufour Atoll 6 presents a rare opportunity to own one of Philippe Briand's most innovative sailing yacht designs. With reportedly only approximately 30 built, the Atoll 6 combines the spacious accommodations and open-concept living typically associated with a catamaran with the traditional advantages of a monohull. Featuring an impressive 16'6" beam, five private cabins, four heads, and a distinctive single-level living arrangement, this vessel offers exceptional versatility as a liveaboard, extended cruising yacht, or income-producing retreat.
Designed with comfort, entertaining, and practical cruising in mind, the Atoll 6 features a seamless transition from the expansive aft cockpit into the galley and navigation station. Its protected deckhouse, panoramic windows, generous accommodations, and thoughtfully designed layout create a remarkably spacious onboard experience.
Currently operating as a short-term rental with a reported nightly rate of approximately $400, the vessel offers additional appeal to buyers interested in an established income-producing opportunity. Cleaning and maintenance arrangements are already in place, with rental income statements available to qualified buyers.

Condition & Showing InformationThis Dufour Atoll 6 offers a compelling combination of rare design, spacious accommodations, recent upgrades, and extensive cruising equipment. The owner describes the vessel as structurally sound and reports reliable engine operation.
Certain items would benefit from attention, including the Lofrans electric windlass, which requires rebuilding, and an unresolved electrical supply issue affecting the Frigoboat refrigerator/freezer. The sails are serviceable, while the original standing rigging should be professionally inspected. Additional 110V outlets may also be desirable.
No current marine survey is available, and buyers are encouraged to conduct independent inspections and a survey.
The vessel is currently anchored rather than marina-docked. Showings are available by advance appointment and require additional coordination. Serious, qualified inquiries are encouraged.
