I was looking for ideas to concoct a GoPro Mount for the back of my boat. I decided to buy a frame umbrella stand, clamp the stand to the back crossbar on my frame and attach a mop handle into the stand. On top I used a roll-bar GoPro mount.
My concerns are if the boat flips and the handle breaks, I could injure others or myself. I bought PVC, but that will break to and it sways. I did try strapping the PVC pipe to the frame with lock pins drilled through the PVC pipe, but it still swayed too much and the straps got in the way.
