The only boats I have ever owned have been canoes. I have never seriously fished from a kayak... just goofed off in them on rare occasions. I use canoes only for fishing and almost always solo. Probably do 50-70 launches a year for the past 45 years. Right now I'm using a 16' Oldtown Camper, weight 60#, easy for me to get it up on the Jeep. Use to do all freshwater but the past 8 years I've done 90% salt. My usual tidal haunts are Patapsco, Magothy, Kent Narrows and Susky Flats, sometimes Gunpowder & Severn. Always use a 35# troller & 2 batteries. Except when doing whitewater trips, I have never capsized or fallen out while fishing... not even close. But then I would never take it out in the main part of the Bay either, CBBT would be out of the question for me.
Canoes are stable enough and hold more stuff then a kayak. These's room for a decent sized cooler, fishfinder, 3 rods, anchor, and a medium sized tackle bag. Wind is a major problem though, get blown all over the place. 10-15mph is my max, anything over 10mph starts becoming a royal pain. Range is more restricted than a kayak. Even with 2 batteries my total range is about 5 miles... thats 2.5 miles away and 2.5 miles to get back... ya always gotta get back! I often hear guys going much farther in kayaks... like 2X or 3X farther than I can do in a canoe.
It all boils done to trade offs. Can't beat a canoe or kayak for poking around piers for perch & pickerel but when out in big open water the risk factor goes way up. Skinny to very skinny water will be your forte. Never have to worry about breaking a prop or bending a shaft like so many big boaters have reported recently. They're easy on the gas too... real easy. Gotta pick your days very carefully though.
Add a second person in my 16' Camper and the stability goes out the window. When solo, I think the trolling motor plus 110 pounds of batteries on the floor adds a great deal of stability.
