A friend of mine and I have been attaching various cameras (Go-Pro, ATC1000) to our paddles and shooting in the waves. The GoPro is definitely producing superior results if you're interested (I own the ATC, so I'm not happy). Or I should say I owned the ATC...took a fall, had the leash line wrap around the camera, then the board got pulled over the falls and the entire thing got yanked in half.
Anyhow great photos available. Blog post here:
