After years of being blown around in a canoe, I finally broke down and bought a yak. I did a fair bit of research (and paddling) before doing the obvious and getting a Pungo. Tracks well, good secondary stability when you're leaning over the gunwales lipping a fish, lots of space, etc., etc. The bigger opening makes for easy in and outs when you want to wade.
One other thought is Chesapeake Light Craft, (http://www.clcboats.com/) especially the Mill Creek. Neat kits if you're inclined to put together your own wooden boat. Count me in for any of your north shore expeditions.
