And it makes clear sense that it was a Navy publication. What do ships have? Electricity, wire, and.... drum roll.... salt water!
Actually, fresh water is worse than salt water if you are IN the water, like a swimmer. This is because fresh water is a poorer conductor of electricity than saltwater is leading to the current flowing through the path of least resistance - the body of the swimmer. (although people always say "current follows the path of least resistance", the statement should really be that current follows all paths in inverse proportion to the resistance of the path).
