I know nothing about that particular boat, but I'll got out on a limb and suggest that you don't buy any boat until you've hunted out of one just like it and decided it will work well for you. (I've never been much good at following this advice.
The other advice I'd offer is to look hard at what other hunters in your area are using. There's a reason that lots of folks on Merrymeeting Bay hunt out of low profile sculling boats or gunning skiffs while the guys chasing eiders are in TDB's, big Lund's, or something similar.
Before you spend a lot of money on a factory-made boat, keep in mind that an awful lot of Maine hunting is available via canoe or kayak, and you can find those used in Uncle Henry's or Craig's List for a few hundred bucks. Ditto for a light 14 or 16 foot aluminum boat with a 10-20 hp outboard, though those will be more expensive.
