Kelly Slater, one of the sport’s most well-known athletes, posted a tribute to the 48-year-old surfer on Instagram after learning about his death.

“It’s taken me a couple days to even want to think about it. Chris Brown and I were nearly inseparable as teenagers. This guy was just such an excited, happy light in my childhood,” Slater wrote as part of a long message.

Keith Malloy, another fellow surfer, also posted about Brown.

“We are going to miss your big smile and enthusiasm CB. I really looked up to Chris Brown as a youngster, he was one of the only guys that could beat @kellyslater in the late 80s and early 90s,” Malloy wrote. “He went on to charge Mavericks and become a Commercial fishermen... what a legend.”

Brown hit the surfing scene as a teenager in Santa Barbara and went on to compete in professional surfing competitions around the world, according to the San Jose Mercury News.
