Hard to argue with the amount of people buying "Funs" for exactly what you are talking about. To clarify I work for JK, but it's built for exactly what you are talking about here. If you get a 4fun (I am roughly your same size), you may want to add a bit (2 inches roughly) of foam in front of the happy feet (between the back of the happy feet and the bow). That will shorten the length of the boat and make it better for your height
There are other river play boats... Fuse, CR, EZG's and even other more river runner focused lines from other brands. But if you are still wanting to mess around at a play park etc... the river/play type boats are exactly that...
