I don’t use a snap shackle any more for the jib, since it stays up for months at a time or more. It is a screw-in shackle with safety wire holding it. The main shackle is one that screws in and out. It has never loosened itself. I think the longest the main has been up continuously is maybe 6 or 7 days and it did fine. Joe Coquina

It has a pivoting arm that swings up after inserting through the headboard and secured with a threaded pin. It has worked fine for years and easy to remove and attach, which I do routinely when done sailing for the day. Recently, I twice found it nearly completely unscrewed after a day of rough weather sailing, and that is concerning. I don’t want to lose the halyard up the mast. I am considering replacing it this winter with a standard snap shackle of the sort used on my genoa halyard. I looked at a rigging company web site and they used snap shackles for genoa halyards and pin shackles for main halyards. The logic of that escapes me. On my boat, I take down the roller furling genoa only a few times a season while the main halyard is detached every time I go sailing. I have no idea what the forces are on the main halyard but I would not think much greater than the genoa. Any words of wisdom, or reason not to use a snap shackle for the main?
