...
Why would the rescuers need to hear anyone shouting for help ?
They'll have been given the location already.
And their boats are all fitted with searchlights.
They're not simply cruising around, sirens blazing, on the off-chance
of finding someone crying for help.
And in any case, what about the sound of the boat's engine ?
Or are you suggesting they should maybe stick to row boats just in case ?
