Brian,
If you are looking for a very low profile boat that will hide in minimum vegetation for very small sheltered waters, I would recommend you take a look at the Kara. They are a 1 person boat, but you can build 2 pretty inexpensively. They are designed for hunting in very low stuff (total height above water surface is maybe 8" or so).
These can be built for somewhere between $250-300 each. These are NOT meant for deep, open water, but are very good for shallow, protected water hunting (though a lot of guys use them in impoundments in sheltered coves, etc).
