Joining anchor chain

I suggest you look at the page on C-links, under Anchoring on my website. I did not test the Maggi links but they don't look too bad. The advice to weld the link is definitely NOT to be followed. These links are hardened and tempered: welding them would convert them back to the annealed condition with about half the strength.

Also beware when buying your additional 10 mm chain. ISO and DIN sizes in 10 mm are different, you can see the dimensions on my Chain page but your gypsy should be marked with the size that fits it.

Thanks for that, had looked at your site already :encouragement: Couldn't see those listed as you say & wasn't really sure if they were OK or nor.

I used one and once I sorted a little problem on PBO forum it worked very well and still have both pieces of chain connected. There have been other posts about these and Vyv Cox I think did something in the PBO mag about chain joiners and I don't think these came out badly. see http://www.ybw.com/forums/showthread.php?391882-Crosby-8mm-G335-Chain-Replacement-Link

Thanks, found a UK supplier for them but aren't sure of their ratings, confused me?

I've used chain joiners with 8mm chain and found the only downside is that they've always rusted within the first season. I've now got rid of the 15m of ancillary chain and replaced it with 100m of 14mm 8-plait. More scope for anchoring depths up to 40m and less weight in the bows.
SWL is not a problem, grade 40/43 has a 40kN break-load and the 8 plait 14mm nylon marginally less. The anchor maximum break-out is about 14kN in good holding and about 8kN in soft mud. Joiners, I guess, are about 50% of chain/8 plait, though, despite Vyv's work on the subject, we don't have a valid population on which to base a quantified load.
Just as no anchor loads are written on stone - apart from the variance with bottoms, operator competence is a much important variable (IMHO) than
anchor design.
So I'd go along with joiners on a lightly loaded chain rode, providing it's changed every 2nd year or it stains and causes rusting on the other links.

PS I donated the 15mm of 26-year-old 8mm chain (unknown provenance, certification and galvanically challenged) together with a worn-out CQR to a Dutch liveaboard trying to set his own mooring in Rethymno. This proves I'm a charitable chap, even though some posters on this site are of the contrary opinion.
