Acts 27:27-29

27When the fourteenth night had come, as we were being driven across the Adriatic Sea, about midnight the sailors suspected that they were nearing land. 28So they took a sounding and found twenty fathoms.
About 120 feet; a fathom (Greek orguia) was about 6 feet or 2 meters
A little farther on they took a sounding again and found fifteen fathoms.
About 90 feet (see previous note)
29And fearing that we might crun on the rocks, they let down four anchors from the stern and prayed for day to come.
