Clue #1 This floats.
Clue #2 It makes noise.
Clue #3 Boats depend on it.
This is a buoy. It makes noise by a hammer striking a bell as the buoy bobs up and down in the waves. The noise allows boaters to hear it in the fog. It is important for navigation, marking a channel that is deep enough for boats to pass safely.
