Oh Heavens! If that's the case, I think it's a pretty obvious answer to cut and resplice. Presuming we're talking about a rope-to-chain splice, it's not a bad idea to renew these splices frequently.
I disagree that a hockle is to be expected from three-strand line that is tensioned and eased. I think it's a sign of an unbalanced line which has not be twisted correctly when made. It's essential that the torque on a twisted line be balanced so that hockling doesn't happen. Yes, it can happen by inducing twist (like circling an anchor in a tidal flow), but should not be caused by easing tension.
I did a test on rope-to-chain splices in the early 90s when the combination gypsies were hitting the market from Simpson Lawrence
and other companies. I spliced up 10 samples of 1/4" chain and 1/2" three-strand line, and five samples of 5/16" chain and 5/8" line, and sent them to New England
Ropes to be broken. In all cases, the splices broke at the last link of chain, but virtually all of them held to 90% of the breaking strength of the line (as I recall). In all cases, the chain links were stretched from 1 to 10% in length, showing that the chain was close to failure. The test was written up in Practical Sailor. CF readers may want to look it up.
