Please show the quote where *anybody* has posted that chain
stretches.

gene, *YOU* did. you may not understand that you did, nevertheless you most
certainly did claim chain stretches, for you claimed that an all chain rode
will not pull an anchor loose or the deck chocks off when the wind and waves
pick up.

The ONLY way for that to NOT happen is for the chain to stretch.

So, gene, just how much do you think chain stretches?
