Newbie question here before I tear things apart. I have only recently acquired this Catalina 22 with the CDI furling. When attempting to raise the jib the messenger seems to get stuck about a third of the way down. I can lift the sail up indicating to me that it is the messenger that is stuck. When the mast is down and I try moving the messenger up and down, it does so relatively easy. The halyard appears in good condition (no frays etc). Before I try to "fix" things I thought I would get your thoughts.
