But roughly 300 years later, a battle over the 300-tonne Queen Anne’s Revenge (built 1710) continues to rage, although now the loot in question is intellectual property.

Intersal, the Florida company that discovered the ship, is preparing a federal lawsuit against the North Carolina Department of Cultural Resources (DCR), according to company chairman John Masters. The potential lawsuit comes after Intersal withdrew its $14m administrative complaint over rights to photos and videos of the historic wreck published by DCR.
