How do warnings, storm measures and final commands lead to all reaching land?

When departure for Italy is determined, Paul and other prisoners are delivered to Julius, a centurion of the Augusta band. They board an Adrumetum ship for the Asian coasts, with Aristarchus, a Macedonian of Thessalonica. At Sidon the next day Julius courteously allows Paul to visit friends and care for himself. Contrary winds take them under Cyprus, across the sea of Cilicia and Pamphylia to Lystra in Lycia, as printed. Julius transfers them to an Alexandrian ship bound for Italy. Slow sailing brings them opposite Gnidus; adverse wind takes them near Crete by Salmone, and with difficulty to Good-havens near Thalassa.

Much time has passed, and sailing is dangerous after the fast. Paul warns of injury and damage to cargo, ship and lives. The centurion believes the pilot and master instead. The haven is unsuitable for winter, and most advise trying Phenice, a Cretan haven looking southwest and northwest. A gentle south wind leads them to think their purpose achieved; loosing from Asson, they sail close to Crete. Euroaquilo catches the ship, which cannot face the wind and is allowed to drift. Under Cauda they secure the boat with difficulty, undergird the ship with helps, fear quicksands and lower the sail yard. They lighten the ship the next day and discard tackle with their own hands on the third. Many days without sun or stars and the great storm remove hope of survival.

After prolonged fasting Paul says they should have listened and not left Crete. He now urges courage: there will be no loss of life, only of the ship. An angel of the God he belongs to and serves stood by at night, saying he must appear before Caesar and that God has given him all fellow voyagers. Paul believes it will happen and says they must come upon an island. On the fourteenth night in Adria, near midnight, sailors think land is near. Soundings give twenty and then fifteen fathoms. They cast four stern anchors, fearing rough places and wishing for day. Sailors try to escape by boat under pretence of setting bow anchors. Paul tells the centurion and soldiers that unless these remain they cannot be saved. The soldiers cut the boat’s ropes and let it fall away.

At approaching daylight Paul urges them to eat after fourteen days without food, for their health, assuring that no hair will perish. He takes bread, thanks God publicly, breaks and eats. Encouraged, all eat; there are 276 souls. After eating they cast out wheat. Daylight reveals unfamiliar land and a creek with shore where they intend to drive the ship if possible. They take up anchors, commit to the sea, loosen the rudders and raise the mainsail toward shore. At a place where two seas meet they run aground: the bow sticks and the stern breaks under the sea. Soldiers propose killing prisoners lest they escape swimming, but Julius wishes to save Paul and forbids it. Swimmers go first, and the rest use boards and parts of the ship. All reach land safely.
