while you're there leave a messanger in place!
Bummer. Its never a whole lot of fun to try and fish things throught he mast. Good luck with it. When you pull the new halyard through, pull and spare light line through with it. That way when this happens again, and it will someday, you need only attach the next new halyard to the messanger (along with another spare) and pull it through.Justin - O'day Owner's Web
