eli5 : how big ship anchors don’t get stuck in the sea bed rocks ?

Question

this question was in my mind for years… if the anchor keeps the huge ship from drifting, how do you get free when you want to sail away ?

Answer 1

For larger ships, the anchor is just the weight that pulls the chain out of the chain locker and it’s actually the cumulative weight of the chain that holds the ship in place.
