Reading Acts 27, the words remind me of communion. Not sure if the people who received the bread from Paul realised it or not, but they actually were delivered from their shipwreck after eating the bread.

"Just before dawn, Paul begged them all to eat some food: “You have been waiting for fourteen days now, and all this time you have not eaten anything. I beg you, then, eat some food; you need it in order to survive. Not even a hair of your heads will be lost.” After saying this, Paul took some bread, gave thanks to God before them all, broke it, and began to eat. They took heart, and every one of them also ate some food. There was a total of 276 of us on board. After everyone had eaten enough, they lightened the ship by throwing all the wheat into the sea."

(Acts 27.33-38 GNB)

God did not need to save every one on board to protect Paul all the way to Rome to do his mission, but his grace was granted to them through Paul. If Paul was not on that ship, they would probably have done the sail exactly the same and die. They lived because God protected them through Paul's presence.

No mention of anybody converting after they survived the shipwreck. We do not know the impact this had on their lives. But this does not lessen the grace that God had, through Paul, blessed them.
