Adam Clarke on Acts 27:11

The centurion believed the master - Τῳ κυβερνητῃ, the pilot; and owner of the ship, τῳ ναυκληρῳ, the captain and proprietor. This latter had the command of the ship and the crew; the pilot had the guidance of the vessel along those dangerous coasts, under the direction of the captain; and the centurion had the power to cause them to proceed on their voyage, or to go into port, as he pleased; as he had other state prisoners on board; and probably the ship itself was freighted for government. Paul told them, if they proceeded, they would be in danger of shipwreck; the pilot and captain said there was no danger; and the centurion, believing them, commanded the vessel to proceed on her voyage. It is likely that they were now in the port called the Fair Havens.
