My 1981 Catalina does not have bulkhead winches mounted for the jib and main halyard. Since I have a pop up cabin top, can mount winches to help raise and trim my halyards or is this not suggested? I had a 1985 Capri that had winches mounted on the deck and they were great and my Catalina does not have them and I have trouble getting the halyards tight enough when I need to. Any suggestions out there?
