Yesterday during a race in light air <8 on the first down wind leg (wind at our starboard quarter) we flew wing on wing which put us out of the hunt to finish respectfully, round the next mark to a reach and made up some ground but not enough on this short leg, next mark took us to DDW we set wing on wing, but with a 3 mile leg we figure lets see what happens when we launch the Asym, our set up experiment was to run the sheet through a cleat on the forward quarter and I will be a monkeys uncle the darn thing filled and stayed filled as long as I maintained 5* either side of 180* true and the boat sped up to almost 7 with a 8 knot wind + a 1 kt current. Everything I have read says an Asym just won't fly on a DDW course but it does and sooooooo much better than wing on wing on our 41DS.
