Albert Barnes Commentary Acts 27:13

"And when the south wind blew softly, supposing that they had obtained their purpose, they weighed anchor and sailed along Crete, close in shore." — Acts 27:13 (ASV)

The south wind. Previously, the wind had probably been a headwind, blowing from the west. When it veered around to the south, and when it blew gently, though not entirely favorable, they nevertheless supposed they could sail along the coast of Crete.

Had obtained their purpose. The object of their desire; that is, to sail safely along the coast of Crete.

Loosing thence. Setting sail for Fair Havens.

Close by Crete. Near the shore. It is evident that they intended, if possible, to reach the harbor of Phenice, to spend the winter there.
