Throughout history, man has been performing rituals at the launch of a new ship to seek supernatural or divine protection for his ship and those who will sail in her. The form of the ritual varies according to local custom and religion: from the breaking of a coconut, to the release of doves, to the role of astrologers in choosing an auspicious day for the launch. But the sentiment that lies behind all launching ceremonies is fear. At the moment of launching a new ship a seafarer is alert to any sign that his ship is not sound. He is superstitious and seeks reassurance that his ship and those who will sail in her will be protected. The rites of blood sacrifice and libations performed by the ancient Babylonians and Greeks are well evidenced. The evolution of this practice into today’s tradition of breaking a bottle of wine against the bow of a ship before launch, still symbolising sacrifice, is explored as well as the now widely practised custom of inviting ladies to name and launch new ships.
