The Pungo is pound for pound the best "all condition" rec boat I know of. I'm a paddling guide in NC and get to test alot of boats. The 12 is a dream but if you can drop some more money down, the 140 going to be faster and straighter and it's made of high density plastic so it wheighs only as much as the 120. It also has a buldhead and hatch for waterproof stowage and flotation if a big tarpon rolls you over.
Either, or. You won't be sorry.
My mother, 63, has two 120 XL's and paddles regularly by herself in them. Deep rivers with some chop.
