The 390 Grand Large presents the next generation of Dufour Grand Large hulls. The signature of Umberto Felci, with the recent innovations inspired from the Dufour Exclusive range, is distinguished by the bulwarks integration and the magnificent hull recess. Furthermore, the important front volume and modern aft shines lines make this hull more spacious and performant. The research that is at the base of the new Dufour 390 Grand Large hull has led to optimizing the ratio between the maximum navigation efficiency and the need to offer ever greater and better exploitable interior volumes. The new hull, wide and flat, which finds its maximum expression downwind, is however very performing even upwind, thanks above all to the new stern to bow hull volumes development
