I've been battling room when pulling jigs and finally got it beat. Double seat leaves me with no leg room and gets In The way, built a bench that worked great but was just to bundlesome.. So I Come up with this idea and it's great.
Used some 2x2x1/8 tubing, drilled holes and welded nuts to pieces of pipe and welded them in so I could use threaded seat poles. I had threaded bases in my boat so I used a 6 1/2" x3/4 bolt to secure it to the boat base.. Zero wobble.. Maximum leg room, nothing to step over, don't have to move anything to open live well or storage compartments,, works great.
Thought I'd share it incase anyone else was looking for ideas.
