UNITED STATES—Sixty six surfers from Huntington Beach ride the world's largest surfboard as they break the 'Guinness Book of Records' record for the largest number of surfers ever to ride a wave on a single surfboard, at Huntington Beach, California. The previous record was 47 and the board was towed into the wave by jet skis before being released to surf a wave for a minimum of 10 seconds under its own momentum.
