Twenty days after a shipwreck, ten sailors were drifting in the lifeboat on the sea. They had only a little water left but were still far from the land. Everybody was thirsty. Snyder was holding a gun and protecting the last drops of water as well as their only hope to survive. The rest of the crew hated Snyder and were waiting for any possible chance to grab the water. Barrett even tried to take action. Snyder pointed the gun at Barrett's chest and forced him to sit down again.
When Snyder was too sleepy to hold on any more . He said to Barrett, "take over, bos'n."Instead of grabbing the water, Barrett did take over the responsibility and protected the water.
The reason for Barretts change is that he was suddenly put in the position of leadership, and began to consider the situation from broader perspective.
