Matthew Poole and continuators on Acts 27:39

39 And when it was day , they knew not the land: but they discovered a certain creek with a shore, into the which they were minded, if it were possible, to thrust in the ship.

In so long and violent a Tempest, thinking every moment to be swallowed up, they could keep no reckoning of the ships running or way; neither were Charts or Maps so usual (if they had any at all) in those times.

A Bay, or bosom of the Sea, having Land on each side; where they judged it most likely for them to get on shore; using still all means for their safety.
