Directed by David Elfick and released in 1975, this a classic surfing documentary.

George Greenough, Ritchie West, and Nat Young are the stars of "Crystal Voyager," a film with a soundtrack by Pink Floyd.

American surfer-cameraman George Greenough rides the waves from California to Byron Bay, using ground-breaking photography to take us inside the tube on his flexible, high-tech "spoon" kneeboard.

At the time of the shortboard revolution, Greenough ignited the imagination of the surfing world and expressed a passion that had lain dormant in the hearts of generations of surfers.
