About the DUFOUR 9000

The aluminum version first introduced as DUFOUR 9000A.

Sailpages Buyer's Take

The Dufour 9000 is a 39.16 ft masthead sloop designed by J. Valentijn and built by Dufour between 1979 and 1984. With a displacement of 19841.0 lb and a comfort ratio of 32.25, this vessel represents a substantial cruising platform from the late 1970s and early 1980s.

Best for:
This boat is well-suited for coastal and offshore cruisers who prioritize a comfortable, stable ride over high-performance racing metrics. Its moderate sail area-to-displacement ratio of 17.62 suggests it is manageable for short-handed cruising.
Bluewater capability:
With a low capsize ratio of 1.81 and a displacement of 19841.0 lb, the Dufour 9000 exhibits strong offshore stability and seaworthiness. Its fin keel and substantial ballast of 9259.4 lb support safe passage in moderate to heavy offshore conditions.
Comparables:
Comparable vessels from this era include the Beneteau 38 and the O'Day 38, which share similar displacement and beam characteristics. These boats are comparable due to their shared role as heavy-displacement, fin-keel cruising sloops designed for comfort.
