Construction to start on Dubois 101-meter sloop mid-2013 Remember when you were wowed by the design proposal by Dubois Naval Architects for a 101-meter super sailing sloop earlier this year? The beast of a yacht is now closer-than-ever to starting construction. The behemoth is set to start build by Q2 2013. Design 380 at Dubois Naval Architects is clearly their largest design to-date. Even at that length and approximately 2000-tonnes she will draw only 4-meters of water with her keel retracted! However, in sailing mode out in the deep blue, the draft can be increased to 16-meters to take advantage of that undersea reach for stabilty.
