From HodgsonHawaii:

This is pro surfer Kalani Chapman getting the ride of a lifetime with a GoPro HD Hero2 mounted on the tail of his board. This wave was from 6/8/2012 at Cloudbreak Tavarua Fiji during the best paddle in surf session day seen to date. To see more surfers, kite surfers, skateboarders, etc using GoPro Hero2 cameras just subscribe to my HodgsonHawaii channel, thanks!
