- The Vernon C Bain Centre
- United States (New York)
Prison ships or hulks have been used for centuries to house prisoners of war and those awaiting despatch to prison colonies. Nowadays some are in use either as a solution to prison overcrowding or for extra security, although cost and political difficulty surrounds the issue. Currently, the largest operational prison ship facility is the 870-bed New York City Prison Barge, The Vernon C Bain Centre, situated on the East River. This forms part of the Rikers Island jail complex, cost US$ 161 million to build and has been in New York since 1992.
