MOBILE, Ala. – When their cruise ship lost power, passengers aboard the Carnival Triumph could have been selfish and looked out only for themselves and their loved ones.

Instead, they became comrades in a long, exhausting struggle to get home.

As ship conditions deteriorated after an engine fire, travelers formed Bible study groups, shared or traded precious supplies and even welcomed strangers into their private cabins. Long after they’ve returned to the everyday luxuries of hot showers and cold drinks, passengers said, they will remember the crew and the personal bonds formed during a cruel week at sea.
