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.

Agnes, 54, vanished Tuesday after he went on a fishing trip, The Guardian reported. It was not immediately clear if the CEO was alone on the boat or had been with other people.

The father of three messaged port authorities Tuesday telling them he was postponing his return due to thick fog, Reuters reported.

Maritime authorities said two boats and three helicopters were involved in the search.

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.

The company said in a statement to NBC News that they were “devastated by this news.”

“The Boardriders family and entire surfing world are devastated by this news,” the statement read. “We are concentrating on working with the local authorities on the search and rescue effort and supporting Pierre's family.”

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.
