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

We had our anchor foul on a giant sea rock. got stuck between the flukes. Had to haul it up, drop it, haul it up, drop it, over and over, around 10 times before it came unlodged.
