Acts 27:17

Which when they had taken up, they used helps, undergirding the ship; and, fearing lest they should fall into the quicksands, strake sail, and so were driven.

and when they had hoisted it up, they used helps, under-girding the ship; and, fearing lest they should be cast upon the Syrtis, they lowered the gear, and so were driven.

After they had hoisted it up, they used cables to help reinforce the ship. Fearing that they would run aground on the Syrtis sand bars, they lowered the sea anchor, and so were driven along.
