Don't swim, float: an optimal strategy for surviving lacustrine incidents
Swimming in the sea could lead to cramp and also means that rescuers would have difficulty locating you due to currents etc, whereas if you just floated, you would remain among the flotsam and jetsam of the wreck and be easier to find. Then please float on water withou moving for long enough to be rescued.
