how did you capsize it to begin with if there was no wind?
With a line from the top of the mast and the help of several friends. At one time, it was a fairly common training drill. The trick is keep one hull stationary. Not as easy as it sounds.
One of the races we'd do at fun sails was a tip & tie. Basically, start and somewhere on the course tip the boat over, tie a balloon to the top of the mast, right the boat, and finish. With two people swinging out on the traps they were easy to tip.
