Hunter06,
I have you looked at Poke boat's?http://www.pokeboat.com/PokeHunting.htm I think they make a model with the single hunter in mind.
I have gone the route of building my own.
It was fun, it was project that I did with my father. My Dad had a great mind for what a duck boat should be, we really didn't have a drawn plan. If he had not been their I have no idea whatI would have ended up with. It was a lot of work. If you wish to email me I would be happy to share.
