RC, you should think about building your own. I can truthfully say that it is easier than building a bow. (just takes a little longer :-))
Here is one called the Mill Creek 13'. You can totally customize it the way that you want with electronics, dry storage, sailrig and more. draft of just a few inches, 36 lbs. , carries 350-400lbs. I have built 3 mill creeks for other people but I plan on building another one for myself sometime soon, for the exact reason and hunt that you are describing. The open cockpit makes these much more practical for flat water paddling, but they still have a skirt if it gets nasty.
The boat below is my first boat, still paddling it. built 15 years ago, 18ft,60lbs, still in great condition.
Ill be taking it to blackbeard island again this december. Its not the best for operating in very tight quarters but unbeatable when you get in the rougher stuff.
fully loaded with 120# of camping/hunting gear.*6 days worth)
the killer combo, camping, paddling, fishing, hunting.
