A prison ship, often more precisely termed prison hulk, is a vessel (usually unseaworthy) salvaged as a prison, often to hold convicts or with the British, often civilian internees, awaiting transportation to a penal colony. This practice was popular with the British government in the 18th and 19th centuries.
