Picked up the new Mylar mainsail about 2 weeks ago.  Also had them build me a new Mylar Jib and Reacher for the bird. All the sails were build for us by Banks Sails in Tampa. They did a great job and super easy to work with.  Looks like we will have about 400 sq ft. of canvas when everything is flying. Have not tried the jib and reacher yet, but in very light wind, the new main and old jib was moving us at close to wind speed. 5 knots in 5-7 knots of wind. And we were hauling 200 lbs of water in the hull from a leaky drain hose. Really excited to try the whole package soon.
