Mine will be as plain as possible to start off (other than Marine Mats installed), but if I should decide to put some sort of back support in, I'm going in this direction. Unfortunately - my awesome seat in the PA is 6 inches too wide to fit the hatch, or I'd be putting in mounts for it. Heck, I still might when I can get a boat to see if it will work...
Learning a ton from the Texas Solo Skiff guys, seat is from Jackson Kayak...
