Thanks to the advice here I ran messenger lines and removed my main and jib halyards. My boat is four years old and this is the first time I removed them. I store outdoors(Chicago winters) mast up in a dirty boatyard. I inspected the halyards and they look good. Do I wash them? How? How often do you have to replace halyards (or another way of asking, how long do halyards last)? Thanks for the advice.
