Great idea. It can be frustrating trying to move and adapt gear from one boat to another. None of them have the same angle or wall thickness of gunwhale.

About 30 years ago, before I got my bass boat, I used to rent boats at multiple lakes and none were the same. I got a portable transducer bracket from BPS, which works great. I used it with electric motor powered boats only, so I'm not sure how it would do with more powerful motors. It worked great, though fish tried to wrap line in it before I got used to it being there.
