Dufour Yachts 405 Grand Large

The Dufour Yachts 405 GRAND LARGE is a 2009–2012 sailboat model designed by Umberto Felci and Patrick Roseau, featuring a fin with spade rudder hull.watch It has an LOA of 12.17 m, a beam of 3.98 m, a draft of 2.03 m, and a displacement of 8990 kg. The hull, shared with the 45-foot model, has a fine bow section and a 4-meter maximum beam.1:00 Construction involves infusion for the sandwich-core deck and topsides, and vinyl ester resin for the laminated hull.1:22 A structural grid of floor timbers and longitudinals is bonded to the hull, and bulkheads are tabbed to the hull and topsides for rigidity.1:36 The 82-square-meter sail plan uses a 9/10 fractional rig with two sets of spreaders.3:06 In 12–14 knots of wind, the boat sails close-hauled at 35–40 degrees with a 130–140% genoa.1:06 The helm is balanced and sensitive, and the boat shows good directional stability with correctly trimmed sails.1:36 The cockpit provides comfortable seating and footrests for windward sailing, but the steering pedestals are low, making the compass difficult to read when standing.2:21
