An anchor is a heavy object attached to a rope that is secured to a ship. It is tossed into the water and sinks to the bottom of the sea so the ship will not drift about. See how you translated this in [Acts 27:13](../27/13.md).
This can be stated in active form. Alternate translation: "had to go in whatever direction the wind blew us" (See: [[rc://en/ta/man/translate/figs-activepassive]])
