Been through the threads looking for discussion of horn vs. clamcleat for halyard(mast mount). Has anyone with clamcleats had a problem with them slipping when the halyard tail is tensioned for a vang ? I have been thinking that two clamcleats (if they don't slip per formentioned)would allow for a jens rig and also keep halyards seperate. Also seems lower profile clamcleat allows a more solid connection if one is using rivets. Any thoughts/experience would be appreciated , Sandy
