Never owned a pontoon boat, but I thought it might be worth a try. I am a 6"2", 250# guy, kinda top heavy (shoulders, arms, torso a bit bigger than average). My concern is the stability of a pontoon boat, underneath me, as I might lean back in the seat, or just shift my weight. would I want to steer away from 7 1/2' or 8' toons, or would they be fairly stable for me? Also, some toons are kinda made like a rocking chair runner, is that design less stable in the water than a flat design?
