CRAIG - Your most recent post has been deleted and I am posting publicly to acknowledge this deletion.
The RULES here for commercial posters say you cannot promote your own product or slam (and innuendo that another product is an inferior knock off of yours IS disparagement on THIS board if not in the courts)...another's AT ALL unless you are asked a specific question to which you are responding. YOU chose to jump in on a chain thread where no question about your product was asked. That is why you have been edited.
I'm getting tired of your constant self promotion at every opportunity on every anchor related thread. Limit yourself to answering direct questions about your anchors and use factual independent data instead of innuendo if you choose to comment on your competitors in doing so. Or PAY for an AD like other vendors.
Thanks Cam for the edit. Craig (and the good moderation of sailnet) is the sole reason I don't bother posting to SSCA and instead enjoy posting here. Craig's posts are also the reason that no matter how good a Rocna is (and I'm not convinced it is) I will NEVER buy one. It'll be a Bruce or Spade for me because of his bad salesmanship and overly aggressive mis-leading posts.
Back to the original question:
I am personally a fan of non-standard solutions and rarely do thing's the "right" way just because I'm told to, so now that you know that is my slant let me ask you a couple questions:
The chain link you describe is not designed as a permanent solution and is not the "right" way to ensure that everything with your ground tackle is bombproof. Will it work? Yeah, probably it'll work just fine but it depends on what keeps you up at night and what you're willing to spend. If you were stuck on the idea I'd just make sure to inspect it occasionally and if it doesn't keep you up at night, great. I personally wouldn't do it because I like my ground tackle to be strong, well designed and oversized. When that one big blow opened up I would be imagining (while trying to sleep) it getting cross loaded over a rock and popping open or something like that.
I also WOULD expect it to jam in your windlass. I added zip tied to my chain before my last trip and the added width of a zip tie on 3/8 chain caused the windlass to not let go of the chain and jam in the windlass 40-50% of the time. PITA. I find gypsies are REALLY picky about chain size, uniformity, etc etc. Is the connector EXACTLY the same size? Will it sit at exactly the same orientation? I expect it will jam. An annoyance more than anything but an annoyance all the same.
Why are you upgrading your anchor setup? Is what you have keeping you up at night? Is your goal to have more holding power and a stronger safer anchor setup? If so I think you could re-approprate the same amount of money and avoid the chain. Buy a used delta for example, or get chain from an industrial supplier. Used chain perhaps.
Why more chain? Chain, in and of itself, does not mean more holding power. Chain allows you to have the same holding power with less scope payed out and gives more chafe resistance. ie chain does not make your anchor hold stronger but rather allows you to anchor in deeper and more crowded harbors with the same holding power.
Finally, what are the limitations of your proposed upgrade? Is it cost? Weight? Storage space? Anchor roller configuration? Take a look at what you're after and what your limitations are. You currently have plenty of chain for chafe resistance and to assist in setting. If all you're after is a stronger setup with more holding power put all your budget into a HUGE anchor. I'll stay out of the debate as to which one but will offer to go with the tried and tested ones not knockoffs. Bruce, Spade, Delta whatever. You might get much better results with your current rode and n 88lb delta for example. Too big? No such thing. It weighs less than a 44lb plus your new chain and costs less too and will have a higher holding power.
If it's reduced swinging in a crowded anchorage you're after than chain (weight in your rode) is what you want. In this case perhaps you could buy a new length of chain and saving money else ware as previously suggested. What about sticking with your current anchor for now and just buying the extra chain?
Just some thoughts to help confuse you further. I doubt you'll be risking anyone's life by using the temporary link but I bet you can achieve your upgrading goals without taking a chance on it.
