Dufour 1800
Deep draft

The Dufour 1800 is a turning point for the shipyard it is indeed the first involvement of an outside architect in the design. But this boat is part of the range of the Dufour 4800, Dufour 3800 and Dufour 2800, so there is no real breakthrough from the traditional codes used by the other models.

For drawing Laurent Cordelle does not follow the latest trends, shapes are classic with a narrow transom bringing stylish design and low wetted surface, but penalizing habitability and performance downwind. A sportier version, called CS came with a specific fin keel and a taller. It is possible to recognize this version by the turquoise-blue hull and spars painted in black.
