Keel laying is a traditional ship-building ceremony which always includes laying some coins on the keel block to bring good luck to the ship and its crew during construction and in the ships future at sea. The team building PO Cruises 184,000 tonnes ship Arvia, celebrated the milestone using specially selected coins from Barbados which were placed under the block before the block was then lowered onto the coins.
