I changed the anchor but not the chain.
Because I have 100 meters (10 mm) stainless steel.
The locker can not store 100 m 12 mm or 14 mm and in Greece sometimes you have to drop the anchor in 20 m deep water.
But I think that 10 mm is too small, the chain is not heavy enough and the boat swings.
For the weight on the bow, I removed the second anchor and its chain, which I never used.
