French authorities have deployed boats and helicopters off the coast of southwest France to search for Pierre Agnes, the chief executive of sportswear maker Boardriders Inc. — the parent of the Quiksilver, Roxy and DC Shoes brands — after his empty boat was found washed ashore. The port authority of the Atlantic beach town of Capbreton said the search was launched after Agnes’ empty boat was found washed up Tuesday in nearby Hossegor. In a statement, Boardriders said that 54-year-old Agnes had gone fishing on his “beloved” boat, as he often did in the mornings, and that he had not been heard from since. “The Boardriders family and entire surfing world are devastated by this news,” the Huntington Beach company said. “We are concentrating on working with the local authorities on the search and rescue effort and supporting Pierre’s family.” Maritime authorities said two boats and three helicopters were involved in the search. The area is known for intense, sometimes dangerous waves that are prized by surfers. Read more at Los Angeles Times.
