A ship replica is a reconstruction of a no longer existing ship. Replicas can range from authentically reconstructed, fully seaworthy ships, to ships of modern construction that give an impression of a historic vessel. Some replicas may not even be seaworthy, but built for other educational or entertainment purposes.
Reasons to build a replica include historic research into shipbuilding, national pride, exposition at a museum or entertainment (e.g., for a TV series ), and/or education programs for the unemployed. For example, see the project to build a replica of the Continental brig Andrew Doria. Apart from building a genuine replica of the ship, sometimes the construction materials, tools and methods can also copied from the ships ' original era, as is the case with the replica of Batavia in Lelystad and the ship of the line replica Delft in Rotterdam (Delfshaven).
