Shipwreck found by schoolboy on Scottish island identified as Revolutionary War frigate later used to hunt whales in Arctic

When a schoolboy going for a run found the ribs of a wooden ship poking through the dunes of a remote Scottish beach, it sparked a hunt by archaeologists, scientists and local historians to uncover its story.

Through a mix of high-tech science and community research, they have an answer. Researchers announced Wednesday that the vessel is very likely the Earl of Chatham, an 18th-century warship that saw action in the American War of Independence before a second life hunting whales in the Arctic - and then a stormy demise.

"I would regard it as a lucky ship, which is a strange thing to say about a ship that's wrecked," said Ben Saunders, senior marine archaeologist at Wessex Archaeology, a charity that helped community researchers conduct the investigation. The group posted video about the shipwreck early Wednesday.
