Dufour Atoll 50 Sailboats for Sale & Market Overview

The Dufour Atoll 50 represents one of the most radical departures in production yacht design, emerging in the late 1990s as a hybrid concept often dubbed a "monocat." Designed by the renowned Philippe Briand, the Atoll 50 was engineered to bridge the gap between the deck space of a catamaran and the berthing versatility of a monohull. Launched primarily to serve the high-capacity demands of the charter industry—most notably under the "Moorings 505" designation for The Moorings—the vessel prioritized outdoor living, shade, and social ergonomics over traditional racing lines. Its silhouette is unmistakable, defined by a massive, permanent hardtop bimini and a cockpit that sits on the same level as the galley and salon, a precursor to the "open" concepts that dominate modern cruising designs today.
