I am in the process of replacing my main and jib halyards and can not tell if they are 5/16 or 3/8. The boat is a 1981 25' Mac and I am going to run the halyards back to the cockpit while I am at it. I bought the boat last year and I am going to replace them with 3/8 unless someone tells me the blocks (if that is the right term) at the top of the mast will not handle 3/8. I took a piece of the line to where I buy some of my accessories and they could not tell either. I am not planning on taking the mast dowm to replace them otherwise I could just check to see if it binds. Thanks for any comments you may have.
