A History of Copper Prices | Winton

In the late 18 th and early 19 th centuries, the primary demand for copper was for sheathing the bottoms of boats, to protect against shipworm and seaweed. Copper-bottomed vessels were both faster and required less docking time than their untreated counterparts. The Royal Navy’s decision to re-hull their entire fleet in the 1780s gave Britain a strategic advantage during the Napoleonic Wars ...
