Wandering on deck and enjoying the fact that he's not effectively confined belowdecks, Aethon doesn't notice the two deckhands disappearing over the side of the boat until he hears the splash.

Turning to the captain, he looks at him with a bit of concern.  "Is it normal for sailors to go for a swim this close to an island like that?"
