One word in the Surfrider Foundation’s mission statement stands out: enjoyment.

"Celebrating is part of it," says Hawaii coordinator Stuart Coleman.

Tomorrow, The Throwdowns, Deadbeats and Analogic rock out at The Fresh Cafe, in the second of four shows sponsored by Surfrider and Kona Brewing Co. to mark International Surfing Day, which comes up Sunday. The concerts celebrate the oceans while raising funds for Surfrider activities.

Throwdowns bassist Kimo Clark is vice-chairman of the Maui chapter of Surfriders, and all the bandmates love the water. "This is a band made up of all very active surfers, with a uniquely Hawaiian sound," Coleman said. Lead singer Erin Smith described that sound as "pretty sassy stuff" in a November interview.

Surfrider is dedicated to the "protection and enjoyment" of the world’s oceans, with a special focus on water quality and access to the surf and shore. The organization emphasizes education, legislative action and volunteer involvement.

The concert tour, which resumes on Kauai and Maui next weekend, after shows in Kona today and Honolulu tomorrow, is part of that.

"We get so much enjoyment out of the ocean that we have a responsibility to take care of it as well," Coleman said, drawing a parallel between the joy of surfing, swimming or paddling and the ethic of this party: "The more you enjoy it, the more you’re going to want to protect it."

Sunday, on International Surfing Day, Surfrider will partner with Surfing Magazine and other local sponsors for beach cleanups on four islands. On Oahu, meet at Diamond Head — look for the Surfrider tent. Get more information at surfrider.org/oahu.
