Hi, perhaps the following will help.It sounds like you there is a problem with the lead of the halyard.Is there a halyard-guide fitted to the mast (about 10" below the exit sheave ) in line with the exit for the sheave ? If not , I would suggest to fit a guider.It is not an expensive item and can be fitted easily with taps or rivets .The guider will ensure a clean run to the sheave and also keep the halyard away from the section when it turns.Hope this helps.
