So, while tinkering this is what I've come up with. The slider tracks are not as beefy as I'd like, but I have another heavy duty set coming. I added some plastic grip tread that is about the same thickness as the sliders so that there is mostly a flat surface. While working and tinkering on this boat I'm really impressed on its design and it is way wider than former boat. Various shots of the seat mounted on the platform, forward, back and also one of me standing on the platform. The last one shows the two pins that prevent the seat from sliding rearward until I pull them to slide back and stand up. In the forward position there are slide stops. I think I'll be getting it wet tomorrow afternoon if the day works out as planned. Let me know what you think.
