Has anyone bought or made a backrest that you can put on the starboard-side middle seat that will lean on the back of the driver's seat? I have a '98 Super Sport that has the flat middle seats, so if you want to face the rider you have to lean back on the backside of the driver's seat, which is slanted the wrong way. I know they build these into most new boats now, but has anyone made their own aftermarket?:
