fter spending more than an hour inspecting the new Dufour 520 during the U.S. Sailboat Show in Annapolis, Maryland, last fall and then sailing the boat in a decent breeze in the days following, our Boat of the Year judges named the queen of the company’s Grand Large line Best Full-Size Cruiser 50 to 54 feet.
