I purchased my 1984 Catalina 30 summer of 2010 and have a laundry list of projects I want to do. As you know, they all cost money. That being said, I have two standard, #40, two speed Lewmar winches to handle the Genoa. I would like it better if they were self tailing. Does anyone know if they could be converted so I can save a few dollars or do I have to change the entire winch? Thanks, as always, for all of your assistance.
