I am about to embark on my first fishing trip on the Mississippi near Chester IL, and Cape Girardeau but now I'm wondering whether I have enough boat for the job. I have an old 17' Chrylser tri-hull with a 65 hp Merc 650. Beam width is roughly 48". It's a clunker but it floats, motor runs good and I can cut bait on the deck and not worry about cleaning it when I get home. Is this too small for the Ol' Miss?
