Here is a copy of a post I put up on another thread concerning the GoPRo mounting. The clamp works great for all types of mounting on an off the boat.
Here is a great forum on the GoPro cameras. (I know, just what we all need, join another forum)
The tips and tricks section is very good for coming up with great ideas on mounting the cameras and getting that tricky postion shot.
Took a time lapse video of our weekend Veteran's boat parade with the camera mounted on top of the tiki bar at the American Legion in Madeira Beach. Used a woodworking clamp with a GoPro sticky mount bolted to the handle and then clamped it to the eave of the roof. Worked great.

Underslot if you reduced the amount of ''hardware'' in the water your resistance would obviously be less. If you drill and bolt one of the ''sticky clip'' mounts to the pole you can get rid of the roll bar clamp. Attach a safety lanyard to the camera in case of catastrophic failure.
Here is the type of clamp I used. It will hold tight on just about anything including a T-Top. It's great because it is quick mount and release.
I drilled two holes in the ''sticky mount' and bolted it to the handle.I removed the rubber handle first.
