I have a legend 37 and over the winter the wind and ice caused one of my main halyards to chafe and separate. I want to replace it but haven't been able to get a chase line down the mast close enough to grab. It gets stuck (?) or blocked by something about 2 feet above the exit sheaves. Is there some sort of restriction there or a plate lining up the lines and wires in the mast or could it be just a bundle of wires with the connectors blocking it. I tried it with the new halyard with a 6 inch section of bicycle type chain for weight, and I also tried an electricians snake. They both got stuck or stopped in the same place. I am open to ideas because I am not looking forward to the bill to have the mast removed to do this. Next I'll be taping off all the openings I can find and vacuuming a light line or thread down to see if that works. I replaced one already by sewing the ends together and pulling the new one through using the old one. Any other suggestions?
