The journey does not go as expected (that is an understatement!). Clearly Luke is on this journey (note the “we” usage). The winds slow the boat down and leave everyone in a dangerous predicament for the time of year. They should have stopped, as Paul prophesies, but they all want to get going with the journey, so they set out. Note how different this is from Jonah’s story – Paul wants to go but cautions vs Jonah’s attempt to run putting them all at risk.
Like Jonah’s story, a storm arises and the ship is wrecked. After the storm starts, they ditch their cargo. After 14 days of the storm, they are without food and Paul prays over a little bread that is left and God provides them some food. There were 276 people on board and all ate enough! They finally run ashore and are stranded on the island of Malta.
