I have an Ericson 29 with standard wire standing rigging. I bought it used this Fall and have not sailed her at all yet.The boat came with a brand new CDI Roller Furler that has not been installed yet. Is this something I can do myself or do I need a yard to do it? I plan on having a yard step the mast in the spring so is it just best to have them do the furler at the same time?Thanks.
