 * Dead-man's Float:

** Before, the daughter's father is telling her to put her head in is hand, while he hold her, and then to look up at the sky and look at the gulls soaring above. He then says, "A dead-mans-float is face down." Meaning, he wants his daughter to go in the water and be face downward, looking like the position of a dead person in the water.

I think the dad might not be suggesting that she should float face-down, but he might be telling her what not to do.
