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

1.07K views

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 ?

You don’t, necessarily. Sometimes the anchor just doesn’t come up and you cut it free and have the divers come back to retrieve it.

Anchors don’t really keep ships from drifting. The anchor hook is just to help the chain set and then the weight of the chain is actually what keeps the ship close to where it anchored. As the ship drifts, the amount of chain off the sea floor (and thus trying to “fall” down) goes up, which means more weight pulling the ship back towards the anchor.

To leave, you take in that chain, pulling you back until you’re basically on top of the anchor again, and then you’re just pulling the anchor out straight up, while its hooks are designed to keep it from being pulled sideways (but still aren’t all that secure against the weight of an entire ship).
