Yeah John, for my use, 60 inches is more than I need. It wouldn't be the worse thing ever, but certainly not going to pay extra for it.
I'm probably 3 years out on a new rig.
The basic White River Jon boat is a pretty basic design. That s why there are so many versions out there. More than one guy has built their own in a garage. Some of those homemade boats look like a giant dog turd, but they fish ok.
