Jon boat hulls handle quite a bit of weight (sounds like you're already
overloaded), but keep in mind that when you sit up on pedestal seats,
the center of gravity goes way up. John boats have no secondary stability
at all, so what will happen is that when someone leans over too far/too
quickly, the boat will instantly turn turtle. Other than that, everything
will be fine

A 12' jon is really too small for two adults and equipment.

I just bought a 12' Tracker Topper last weekend and a 30lb trolling motor
and battery. With my friend and I and 4 rods and each of our tackle, an
anchor, and a small cooler the motor handles it fine and the boat seams
pretty good considering the load. How much more weight can I add to that
thing before I am testing it limits? I would like to put a platform between
the front and middle bench and then put some type of swivel seat on that
platform and then on the rear bench. How high do you think can go with the
swivel seats before the boat becomes to unstable and do you think it can
handle the weight of the wood for the platform? Any questions please ask,
thanks.
