Kayaks are my favorite,but I've never paddled a solo canoe so maybe they're very good also.  It's much easier to fish out of a canoe when sitting higher in the seat.  Seems the solo canoe is less forgiving in windy/wavy conditions than a kayak.  I don't know why more solo canoeists do not use a canoe cover.  The cover keeps you drier, warmer, makes upwind easier because you're more streamlined and catch less wind, and prevents any rogue waves from splashing into the canoe so it is vastly more sea-worthy on rough days.
