So. . .how do you do it? My old closed turnbuckles had jamb nuts. . .I see a hole in the end of the studs, so I put a pin or something in there?

Two choices: cotter keys through the hole and wrapped on the turnbuckle (ankle scratchers) or as I prefer, spring rings looping the turnbuckle and the pin together.

Open turnbuckles are the way to go and Andy has the solution.

Iprefer the rings

I prefer the split rings over cotter pins. Much less sticking out to bite you when your in a hurry to do something. And OH YEAH Make sure they are stainless. Couple years ago I lost a forestay, because the PO had used a cotter pin that was not stainless. Total cost before it was all over was about 2K, so be sure which ever you use are stainless.

My open turn buckles also have lock nuts in addition to the rings. You can also use stainless lock wire.

I agree, the split rings are nicer. But, just be careful with them. My boat came with them, and removing them and replacing with cotter pins was a "major finding" by my surveyor. Don't know why the rings are "bad" but they are.

My understanding is that a "circlip" or split ring may get caught on a sail and work its way free- and that a cotter pin (because the ends are bent over) is way less likely to be inadvertently removed should a sail snag on the cotter pin. On the advice of a rigger, I replaced all my circlips that were in range of being snagged by a sail with a cotter pin.

On my old Mac 25, where the chain plates are on the edge of the boat,the side stays kept snagging the sheets and would get yanked out, until I replaced them with cotter pins. The open turnbuckles ring dings are a little more protected and the chain plates are not as exposed to the sheets on the Cat 27 so I kept the rings there with no problems so far.

my boat is big'n'heavy.. cotter pins are used to keep the turnbuckles--and they are bent far enough to remain inside the turnbuckle--- cotter pins are heavier than cotter rings, and will work well for along time. there are no cotter rings on my formosa.

There is another method on securing turnbuckles as exemplified by Brion Toss, a rigger in Port Townsend (WA). Use either stainless steel or bronze welding rods that will fit the holes in your turnbuckle. Cut a piece of the rod big enough to make a letter "C" so that the ends go through the turnbuckle holes, then fold back into the turnbuckle.

This looks much better then cotter pins and you don't cover the turnbuckle with tape which prevents air from getting to the stainless steel causing erosion. I have done this for a number of years--the welding rods are cheap and they look good when all is done. Don't tape.

i dont use tape--my cotter pins are bent back into the turnbuckle and rendered harmless!!!

what you describe, stu sounds coool---is it easy to change out in wind and sea while underway? i can change a cotter pin fast and bend it out of my way--it takes both hands but i can do it---mebbe i am just not seeing it right, or from the right point of view.....do youhave a pic?

Found the thread, but no pics. . .

Is it rude to PM someone and bug them for pictures?
not sure about that ...it depends on the person i guess...as for contacting Roger he is on a mission and may not have the pics with him and i remember him saying something about not sending pics from the mobil till he knew how the data chargers were going to be but i am sure that if he were in port he would be glad to post them for all to see....maybe someone else has done this and could provide pics ....i would but my boat is in a state of dissasimbly at this time and would not be able to post that ....
