Professional Windsurfers Robbie Naish, Frank Baensch, Scott Carvill, Alex Reinprecht, Fabrice Beaux, and Josh Stone take us to their playground in the waters off Diamond Head where we learn that the real diamonds lie not on the dusty slopes of this world-famous volcanic crater, but in the opalescent summer waves. Showcasing their most radical moves on some of the best days, these pros are able to push the limits incredibly far because the consequences are not as harsh as in the unforgiving waters of the North Shore.
