Crystal Voyager is written and narrated by the eccentric American surfer and filmmaker George Greenough, who pioneered the earliest surf film footage shot from the water. Structured as a loose biography of Greenough and predominantly shot in California, the film focuses on his trials and tribulations as he attempts to finish making his oceangoing yacht Morning Light, which he intends to use to find uncrowded waves. The closing sequence of slow-motion footage shot inside the curl of waves, edited to the Pink Floyd song “Echoes,” is staggering in its beauty.
