Dufour 455 Grand Large Information, Review, Specs

The Dufour 455 Grand Large began production in 2006, emerging from the shipyards of Dufour Yachts, a builder with a long-standing reputation for pioneering fiberglass construction. Dufour's commitment to robust construction is evident in the 455, featuring a solid fiberglass hull and a meticulously crafted fiberglass deck, often utilizing an infusion process known as DAT®. The design team of Umberto Felci and Patrick Roseo aimed to create a yacht that balanced assertive design with a clear identity, aligning with Dufour's emphasis on high-performance sailing yachts. The "Grand Large" designation itself signifies its purpose as a capable cruising vessel, with the hulls designed to be slightly deeper and fuller to optimize space for cruising amenities and gear. While specific variations like MkI or MkII are not commonly cited, some models were offered with "Adventure" or "Grand Cruising" packs, occasionally including a taller rig, indicating optional configurations rather than distinct model iterations.

Sailing Performance and Handling

The Dufour 455 Grand Large, with its fin keel with bulb and spade rudder, is engineered for a balanced and responsive sailing experience. Its sail area to displacement ratio (SA/D) of approximately 16.8 suggests a boat that is performance-oriented, with ample sail area relative to its displacement, allowing it to accelerate quickly and perform capably in lighter wind conditions. The ballast to displacement ratio (B/D) of about 0.29 indicates a stable cruising platform, designed to stand up to a good breeze while maintaining comfort, though it is not as stiff as some dedicated performance racers. With a displacement to length ratio (D/L) of approximately 172.1, the 455 Grand Large falls into the lighter end of the cruising yacht spectrum for its size, contributing to its responsive handling and respectable speed potential. Anecdotal accounts often describe the Dufour 455 Grand Large as a "great yacht for sailing" that can "release the carefree sailor," implying an enjoyable and manageable experience on the water.

Accommodations and Layout

The interior of the Dufour 455 Grand Large is designed for comfort and functionality, typically featuring a spacious layout with three cabins and two heads, making it well-suited for families or multiple guests. The joinery work throughout the yacht is finished in prime choice Moabi mahogany, with details such as fiddles and mouldings enhancing the classic marine aesthetic. The saloon boasts a comfortable headroom of approximately 6.4 feet (1.95 meters) and is often adorned with alcantara cushions, providing a luxurious feel. The galley is equipped with essential cruising amenities, including an oven, an electric fridge, and a freezer. The design prioritizes storage, leveraging the fuller hull form to provide ample space for provisions and personal gear, essential for extended voyages.
