Depending on the size of your boat generally a 3/8 rope halyard will work. However you may need to change the sheaves on the top of the mast. Not generally a big job. You could also use a rope/wire halyard. Not my preferrence but they work fine and don't cause a problem with the sheaves. If the winch is on the mast it does not need to be self tailing but you will need a cleat to tie it off.
