The ship went down, and Max was the sole survivor, washing ashore on an island, surrounded by the bodies of his shipmates.
He gathered up all the driftwood and vines he could.
And he made a raft.
A sail tied together from clothes of his dead shipmates.
Getting a sense of the currents and waves and winds.
Raising the sail and setting out, he vanished into the horizon.
That night, a ship found the island he’d been on and collected the bodies.
“I guess there were no survivors,” said a deckhand.
Maybe the heat stroke made Max dream that up?
