It may be too harsh to suggest that the crew of the ship had delusions of adequacy. But they certainly did have to face challenges for which they were ill prepared. I say that because Luke makes two statements in this account that show how bad the situation really was. He says, "we," twice. "We," Luke writes, "gave way to [the strong wind] and were driven along." Then, "we managed with difficulty to secure the ship's boat." It seems Luke was pressed into service in the face of the terrifying storm.
