This summer my main halyard broke and fell down my mast. All summer it was becoming more and more difficult to pull the main sail up. I am wondering if there is a pulley at the top of the mast that may have frozen but I can't find any diagram of the top of mast to know. I am also wondering about my spinnaker halyard. I have an opening in my mast for one but I do not know if it exits the mast in the same opening as my jib halyard does or if there is another.
