The clutch for my main halyard refuses to stay in the open position which makes it difficult to drop the sail when single -handing. As a temporary solution, I swapped it into the clutch and block for the Spinnaker halyard. I think I can find a quad clutch online and would like to replace it when on the hard. I understand that the OEM clutch is screwed into a threaded plate glassed into the deck. I understand, further, it can be difficult to remove the original clutch without stripping the threads in the plate. Has anyone replaced their starboard clutch and, if so, what are some pointers to do it successfully? Also, any advice on what model replacement clutch to get? Catalina Direct doesn't seem to carry a quad clutch. I want see if I can match up the mounting holes. Thanks!
