Ok, it goes back to the early days of sailing, about the middle ages, when the place for the crew to empty the bowels was located as far away from the Captain's quarters as possible. As he was at the stern, the bowel relieving section was at the front, in a part of the ship called the "beakhead". This was just under the foredeck, where there was an open area for 'mooning the porpoises'. It was stark and open, but sufficient for the purpose. It soon became shortened to "the Head", and has become part of the sailor's jargon, and is used to this day. people like to say that
on a boat, it is called a "HEAD".
