I had this happen to me also. What I do is just have one person hold the main halyard and have the other person feed the ripped section through the sail feeder, once you get it through the little sail feeder, it shouldn't bunch up in the sail track. If it does bunch up, you could always cleat off the halyard and tip the boat over on her side to fix it. I haven't tried sewing it yet though, but this may be more practical especially if you are short on time.
