We pulled the Lewmar
G4 chain from out locker a while ago and found that about 25 feet of it had become unsafe to use as anchor
chain. Now it wasn't the first 25 feet. That was fine. As a matter of fact, the first 75 feet was fine. From 75 to 100 was worthless. From 100 to 300 feet was also fine.
Any one have any idea why the first part was fine and then a chunk was bad and then the rest if great. If it was saltwater corrosion
in the locker, it should have gotten all the chain clear down to the bottom. It can't be abrasion as the first section it what sits on the ocean bottom. this is the section that is off the bottom on it's way up to the deck
and not really much of that as we typically let out 150-180 feet of chain.
I'm a bit mystified.
