Sean Collins, a Hall of Fame surfer whose online company revolutionized the way surfers tracked waves, has died at the age of 59.
Collins, the founder, president and chief forecaster of surfline.com, suffered a heart attack while playing tennis Monday and died at Hoag Hospital shortly afterward.
Surfer magazine named Collins one of the 25 most influential surfers of the century in 1999. He was inducted into the Surfers' Hall of Fame in Huntington Beach in 2008.
In 1995, Collins founded surfline.com, which features free surf reports from around the world. The Huntington Beach-based company became an essential online destination not only for surfers, but for lifeguards, the National Weather Service and even branches of the military, who used it to predict ocean conditions.
"Sean's many accomplishments in surf science and forecasting made him one of the most influential surfers of our time," the company said in a statement. "Surfline's entire staff — as well as countless surfers worldwide — are in a state of shock at the news."
