I have recently purchased a 1985 Catalina 30. She came rigged and I am no trying to figure out how the Jib is hoisted into the roller furling. I can account for all three halyards but none of them a attached to the top of the jib. How is it Hoisted? I know that it works on some sort of car device but not exactly sure. Basiclly how does the sail get to the top of the mast?
