Do yourself a favor and go with a boat styled like "The Duck Boat". We have unique conditions in the northeast compared to other areas of the country ,especially when it come to hunting the salt water and tidal marshes.
These are boats designed for waterfowling ,not jon or row boats, with their origins from coastal Maine. They are a bit more but well worth every penny. Personally I go with with two boats , Osage Canoe makes a aluminum duckboat that is great for marshes where you don't have to worry about having to cross water that can get rough under changing conditions.
here is a link to style I talked about
http://www.hightechsportingboats.com I Don't have link to Osage off hand but the "sneak box " design is rated for either 10-15 hp if i remember right and can carry something like 750 lbs which is more than enough for 2 hunters dog and dekes. If you can only go weth one , go with the "duckboat" style.
