Everytime I had to use the Hobie Latrine(mirage drive opening), I was getting annoyed by my fishfinder shade rubbing up against my side. So I decided to make a PVC mod to be able to swivel it outboard to give me more space as needed.
It reminds me a little of a cactus. The base is made out of cutting boards, the stainless steel was a piece from the transom mount that came with my fishfinder. In the finalized version, I swapped out the ball mount for a socket as with an arm connected it was going to be too high.
By loosening the wing nut on the top, I can swivel the arm out when needed.
It is stable and serves its function well.
