stainless steel rings

My local chandler carries SS rings up to about 2 inches. Unfortunately he does not have a catalogue on his web site.
www.yacht-grot.com.au (do you like the company name?)
Anyway I can't imagine how one would use SS rings in clipping onto a jackstay. One uses a snap shackle on the end of a webbing strap. However not any snap shackle but one that requires dual action to release as single action types can be inadvertently released. This is expensive but approved for the job. https://www.whitworths.com.au/main_...&intAbsolutePage=&LinkedItem=74364&search123=

Haven't seen the article, but I imagine the rings are threaded on the jackstay and then the lanyard is attached to the ring. Not sure what the benefit is supposed to be over clipping directly, mind you.

Anyway, simply googling stainless steel rings found me several suppliers; adding -jewellery stripped out most of the rings of the engagement and signet variety. s3i came up and would certainly be a reputable choice, although their site is "down for maintenance" right now which is unfortunate. Although for most other purposes I'd just pick whoever was cheapest on eBay...

Like olewill I have double latch safety harness clips but if you wont stainless rings you really need D rings like these

clips.
 
I think the idea of having a generously large SS ring permanently on each jackstay seems excellent, as clipping the snap shackle to the ring avoids the snagging which seems to sometimes occur when moving along with the shackle attached directly to the webbing strap.
 
Ebay, bought them for rigging anchor on my kayak. Just search A4 stainless rings, even d rings show which would be ideal for jackstays.
 
I would also recommend SS rings on jackstays.
When moving around, I invariably find that the webbing will get caught somewhere in the clip. If you clip onto the ring you prevent that happening.

I'm with you this. I used to to have a pair each side, and this was quite common a couple of decades ago, IIRC. My impression is that it has gone "out of fashion" lately.

They do need to be quite beefy! I note Jimmy Green's website does not quote safe working loads for their rings - they probably have the data available if asked, but I'd have thought you should be looking at the 8mm rings. Other suppliers list similar at somewhere between 4 and 5 tonnes SWL which I think is what you would need to keep the whole jackstay/ring/tether combination in line with usual guidelines/regulations.

I think this is way over specified. ISAF regulations for offshore racing specify (section 4.04 a) iv ) which applies to MoMu0,1,2,3 - i.e. all - that the breaking load of the jack stays shall be 20kN, so about 2 tonnes. Some fit 3 tonnes, but that's for the stays. The person going over will exert a sideways force on the jack stay which will multiply the strain in the jack-stay several-fold compared to the force exerted by the person. Hence in principle well under 2 tonnes is all that's required. And frankly, I don't want 5 tonnes exerted on me by my harness: it would pull through me like a cheese wire!

So just about any ring will do: I'd go for 5mm.
