David,

I did not check out your link, but the limits sound about right for a 12' jon boat. I used to have one, and I am a big guy... really big. With me, the TM, battery, and a small tackle box, the boat was really unsteady, and if I moved around much, it took on water in the back.

I'd love to have another, but it will be no less than 14', and possibly 16'.

I know my last boat would hold me and my wife, but we had to be very careful as it set very low in the water.

Good luck,

Tight lines and God Bless

Danny
