I have two kayaks I hunt alot out of, that being said i do not take them in many tidal marshes, the title says it all. Tide. Some beutiful and very "ducky" marshes have a extremely strong tide. Where will you be hunting? The del side of NJ is a totally different ball game, alot of the marshes have very strong tides and are actually very deep, not to mention the mud.
I have had a great day out on the bay out of my kayak though, I paddled way out and was fine, just use your judgement on weather conditions, don't wear waders, and stay away from strong tides. I know I'm talking about a kayak not a canoe but same principles apply only I personally do not like canoes. Good luck and be safe.
