Thanks Dan, very detailed indeed.

I like to do them like this, at least on the turnbuckles. The sheets are routed outside the stays, so nothing snags, and a quick glance confirms that they haven't moved.

Tim,

Those turnbuckles are going to stay as set with the way you have the cotter pins bent back.

Yeah, I don't think they're going anywhere. The boat came to me with large circlips instead of cotter pins, which I was never too crazy about. When I replaced and re-tuned the standing rigging 2 years ago, I put in those proper cotter pins like this, and they haven't budged since.

I have the Velcro wraps, and they work pretty well.

I like the concept of the velcro ones, but I'm so OCD that I'd wear out the velcro, constantly opening them to make sure the pins are still in! ;~P

I used them on the forestay since they made it easy to loosen the turnbuckle before lowering the mast. I had a piece of tape wrapped around the threads so I knew how much to tighten the turnbuckle when the mast went back up.

Alas, they're too big to fit under the furler drum so I'm going to need to do something different.

I used these, Tim: https://defender.com/en_us/c-s-johnson-wrap-c4-p-wrap-pin-wrapc4-p?utm_id=147314937780&utm_campaign=19735474064&utm_source=google&utm_medium=paid&utm_content=649599819268&gclid=Cj0KCQjwla-hBhD7ARIsAM9tQKsamK_lrLNifeL04umGVVtGBdz3cl1dRGS5m4RjxJ1IvVw4HPczteQaAvNmEALw_wcB

Brian S linked me to them. They seem very secure.

I have them on my forestay too. I don't have to undo them because I use them thar quick release levers on my shrouds: https://www.westmarine.com/c.sherman-johnson-small-7-hole-quick-release-shroud-lever-246175.html?utm_medium=cpc&utm_source=google&utm_campaign=PMax%3A%20GSC%3ESmart_Shopping%3ESailing&gclid=Cj0KCQjwla-hBhD7ARIsAM9tQKvRTpY-WbKlSMi7bRtjr5-3buMMG0MuBBCUlKOUhJQ-iBdkX9etVwsaAoY3EALw_wcB

Great idea with the tape Tom. Yeah, CDI says cotter pins only for the forestay turnbuckle. Maybe get some of those levers Frank mentioned for the shrouds?

I'm sure they're secure enough Frank, but I'm a "gotta see it with my own eyes" kinda guy. Growing up, my family nicknamed me Doubting Thomas ... ;~P

Whether using cotter pins or split rings, tape the fastener. A sheet or other line, or even a crew member's sock, can snag the  sharp end of a pin or clip and start to open it. Plus, it can foul the line or draw blood. If you rig seasonally, you can get by with cheap electrical tape. You'll replace it every year, but you have to take it off anyway when you put the boat to bed for the winter.

Talbot, I don't like to tape them for the same reason I don't like them covered by anything else: because I want to be able to see at a quick glance that they are secure. No lines or socks ever get anywhere near them, so there's no snag issue.
