I posted this in the other Mariner 4 thread, but has anyone made benches for the boat that rest on the inflated portions? I tend to set on one of the tubes perpendicular to the boat to run the trolling motor but I've wanted to put in some bench seats for a while. Most people seem to put in a solid floor and add pedestal seats, which I don't really want (adds something I have to build at the boat launch). I think benches seem like a great idea because they literally just sit in place and are easy to store/install quickly. I can't figure out if just a plank will do or if it should be more complicated than that.
