Dufour A9000
Deep draft

Dufour A9000 is born thanks to the experience gained in the design of France 3, the French America Class for which the architect Johan Valentijn and the shipyard participated. She uses the same construction material: aluminium, giving the A of the name. This is so far the only sailboat from Dufour in this material. The structure has the distinction of having continuous frame, longitudinal stiffeners stopping a few inches before.

On deck we can feel the race atmosphere with a T-shaped cockpit, a large set of fittings and a big wheel. The sail area is also performance oriented with nearly 100sqm – 1080sqft upwind. The interior is, in contrast, very warm and well equipped. The headroom is more than adequate as long as we remain under the long coach-roof.
