I had a 1430 with a little 5 horse outboard, fuel tank, trolling motor, and battery. I only took it out a half dozen times. I'm 6'2" and 260 (oddly, named Jake) and it made me pretty uncomfortable. This coming from a guy that is very used to being on boats. Thankfully, I just used it for duck hunting. I never stood up in it other than it's first maiden voyage in July. When I was duck hunting, it made me so nervous that I would run it up on the bank before I got out. No need taking chances.
About 10 years ago I did have a 1436 Alumacraft jon with a Electric start 9.9. That boat was still a bit tipsy, but was so much more useable and safer. In my opinion, being a fairly large guy, you will want a 1436 at a minimum. Pretty much any 14' boat with a floor 36" or wider is good to go. I sold that 1430 and picked up a Vhull. The V is 14' long too, but it's 50" wide at the bottom. 2 people can actually get up and walk around at the same time. Some of the wide bottom 12' boats should be okay, too.
Good luck with the search. I just checked Craigslist on a daily basis until I found a good deal. I got a 14ft V hull with trailer, 10 horse outboard, fuel tank, new battery, and trolling motor for $550. The next day I saw where a campground was selling off their fleet of boats and they were selling 14' Alumacraft Vhulls in great condition for $350. looking back, I should have bought one of the Alumacrafts too!
