A museum ship, also called a memorial ship, is a ship that has been preserved and converted into a museum open to the public for educational or memorial purposes. Some are also used for training and recruitment purposes, mostly for the small number of museum ships that are still operational and thus capable of regular movement.[1]
Several hundred museum ships are kept around the world, with around 175 of them organised in the Historic Naval Ships Association[2] though many are not naval museum ships, from general merchant ships to tugs and lightships. Many, if not most, museum ships are also associated with a maritime museum.
