Franck Cammas, one of world’s most accomplished sailors, has done what no one has done before. He rounded Cape Horn in a 20-foot foiling catamaran.

Cammas rounded Cape Horn in a Nacra F20 Carbon FCS. Novice sailor Johannes Wiebel, of Germany, accompanied him.

Weather conditions were good for the passage, with 15 knots of wind and 8-foot seas.

“It’s been a really great and successful adventure,” Cammas said after getting back on land. “It’s unusual to have a weather window in 10 days for a boat like this to round Cape Horn. It’s my third passage, and it’s really uncommon to do it with such a small boat.”

The passage with a novice sailor was part of a promotion by the eyewear manufacturer Julbo.

Cape Horn, at the southern tip of Chile, marks the northern boundary of the Drake Passage, where the Atlantic and Pacific oceans collide. The waters there can be particularly hazardous because of a combination of wind, strong currents and icebergs.
