Its three-digit number characterizes the Dufour 455 as a Grand Large model. To accommodate cruising gear, the Grand’ Large hulls are deeper and more fuller forward and aft than the other hulls. As befits cruising boats, their sail plans are less lofty and well adequate, and their keels shallower. Both lines share an attractive look, lean and linear with nearly plumb bows and low cabin trunks. Design by Umberto Felci. Fully equipped for week charter. Fuel consumption per hour (min/max) = 15 / 25 liters.
