I second slab, I use the gopro to film POV bow shots while hunting and have tried using it on the boat. No sound if you keep it waterproof, cool video and time lapse features on it. I will use my cannon camcorder for recording, since it has a zoom. If you are really going to get into filming fishing get a good wind screen on your mic and some lapel mics for voice! Nothing is worse than listening to wind drown out the voice on a fishing video.
