French authorities deployed boats and helicopters Wednesday as part of the desperate search for Pierre Agnes, the chief executive of sportswear maker Quiksilver whose empty boat was discovered washed ashore Tuesday.

Wednesday's search focused on the coast of southwest France one day after Agnes’ boat was found on a beach at Hossegor, about 20 miles north of Biarritz.

Quiksilver, known for its surf wear, was founded in Australia but is now majority-owned by an American investment group and based in Huntington Beach, Calif. Agnes was the head of its France-based European headquarters before being named CEO of the whole company in 2015. Agnes has been with the company for some 30 years.

Kelly Slater, an American professional surfer, posted on Instagram that he was “praying for a miracle” in the search for Agnes.

“I love this man. Pierre Agnes went missing in Hossegor today when his boat washed ashore in the cold, early morning fog. I’m praying for a miracle but it’s just starting to hit me what a profound effect this man had on my life and the surf community at large. He loved his morning fishing trips, family, Quiksilver, surfing, friends, motorbikes, Capbreton...I’m not even sure how to let it sink in,” he wrote.
