I have a 1988 Oceanis 430. As fas as I can tell, there is no built-in spot for a bail and block. There is a place in the mast for a spinnaker halyard which is marked at the halyard exit on the port side of the mast. I want to install the halyard above the forestay. Does anyone have any information as to what I need to outfit the masthead? This is for an asym spinnaker. Thanks
