A day after activating his emergency beacon, an 84-year-old American making his seventh attempt to sail alone around South America’s Cape Horn was found by the Chilean navy.

Thomas Louis Corogin was found Wednesday on his 32-foot sailboat more than 520 miles south of Easter Island. The boat’s mast had broken far from land in the South Pacific.

It was stranded in relatively stable weather, but with ocean swells of about 15 feet.
