If you have a wide angle lens GoPro type camera, you might like to try this sort of mount. I enjoy making videos, but I don't have the natural kitesurfing talent to make them look interesting without a lot of camera angles!
I made it out of fibreglass, but plywood would be just as good. The counterweight (a few large sinkers) was an afterthought, but puts the c of g in the middle of the back which is more comfortable. You don't notice it much, but it's a little more intrusive than a kite camera or board mounted camera. The straps are luggage tie downs from bunnings.
Here's a video using the mount, plus a couple of frames from the video...
P.S. Yes you do feel like a dork wearing this!
