John Rousmaniere has also advocated the use of cotter pins over ring-dings elsewhere on sailnet as well. He was not expansive on his reasoning other than he'd had ring-dings fail in some way.

I've used rings for turnbuckles in the exact manner you show and I think that is their best application. I'll try and source some of those larger sizes. None of my local riggers seem to have much of a selection and most use cotter pins. I actually like rings on turnbuckles because it makes tuning the rig faster and your more likely to make the tweaks to your rig mid season that you know you want/need..

I still don't feel comfortable with them on the clevis pins after that Pearson experience and BTW the pin was the right size for the hole. As I said I suspect a slack rig under downwind loads and too long of a pin were also contributing factors...

sailboy21 is on a distinguished road
I have read in more than one "how to sail around the universe" style book that using a length of 3/32" TIG welding wire, or tapping the hole and screwing in a small machine screw are superior to cotter pins or rings. I haven't tried either of these methods yet.... I have been using a mix if cotter or split rings. It depends on whatever seems to fit the hole "best." The shroud turnbuckles always end up getting a dose if rigging tape, which isn't applied directly to any of the stainless parts so it shouldn't be a problem.

In any event, rings, cotter pins, TIG wire or even nothing at all is superior to those jam-nuts I see every now and then. What a bad idea that was!
