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 the Pink Floyd. American surfer-cameraman George Greenhough 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, Greenhough ignited the imagination of the surfing world and expressed a passion that had lain dormant in the hearts of generations of surfers.
