I spent several years as an
entertainment director on cruise ships.
In order to work on a ship you are required
to attend frequent lectures in water safety.
Considerable time was devoted to what you should do
if you accidentally fall overboard.
It was recommended to us, not to panic,
but to slowly remove all our outer clothing.
However, we were warned to be certain that
the blouse always is taken off last,
because the air gets under the blouse and acts like a buoy.
It was also recommended
that we should always carry a bar of soap...
Because we could be certain to be washed ashore...
