French sailor Louis Burton’s boat Bureau Vallee was hit by a trawler overnight Tuesday, organizers for the Vendee Globe race said, in the latest collision to befall the non-stop, solo round-the-world yacht race.

Burton, who at 27 is the youngest competitor, was uninjured in the incident, which happened about 400 nautical miles off the coast of the Portuguese capital of Lisbon.

“He was on watch in the cockpit and his radar and AIS were switched on. He was travelling at 18 knots in heavy seas with a southwesterly wind of 32 knots and limited visibility,” race organizers said.
