I have a jib line(furling) that runs aft through a couple of fairleads along the deck, but there is nothing to tie off to except the stern cleat. I would like to set the line up so it runs through a cam(exit?) mounted on the aluminum toerail aft of the companionway, so its easy to singlehand. I think that if I mount an exit cam just aft of the pedestal, the 90 degree angle will be just right to work singlehand. I have seen it on a few other boats in the harbor.
My main question is how do I mount the cam to the toerail? Is there a better option?
Thanks
