'Anchors' in the Bible

Then, fearing we might run aground in some rocky place, they dropped four anchors from the stern and prayed for daylight to come.

Some sailors tried to escape from the ship; they had let down the skiff into the sea, pretending that they were going to put out anchors from the bow.

After casting off the anchors, they left them in the sea, at the same time loosening the ropes that held the rudders. Then they hoisted the foresail to the wind and headed for the beach.
