Here’s a couple of links to Errantsurf.com, one that will be interesting if you haven’t already bought into the GoPro range of action cameras, and another that is worth a read whichever tiny video camera you’ve ended up with.
The Top Six Action Cameras: http://blog.errantsurf.com/2014/03/top-six-surfing-action-cams/
Tim Nunn does a good job describing the attributes of the 6 cameras they highlight in the article, GoPro comes out on top but there are some other options there too, I’ve personally used a Contour, Drift and JVC action camera as well as 5 generations of GoPro’s from 35mm to the current flag ship Hero 3+ black edition, and my experiences match the article.
The second post is about where to mount your camera for shooting surfing, if you ride a bodyboard have a look at the board mount post I put up a little while back for some other ideas, if you mostly ride stand-up there are some good pro’s and con’s of different angles here:

There’s some good information and plenty of examples included in both posts, I will hopefully be getting my Flexible clamp mount involved with a new surfboard purchase of mine soon, just need the right conditions, after which I’ll put up a how-to on a slightly different angle from the one’s mentioned in Tim’s article.
