Re: boat width
You can fish/boat safely on the Mississippi from a canoe if you understand the river and know how to avoid barges. You simply need to stay away from them as the bow wave will swamp a small boat. If you approach a curve, well before you get there, swing to the outside of the curve to see if a barge is coming. If not, continue on your way. If a barge tow is approaching, you should get the the inside of the curve and as close to shore as you can. The barge tow will aim the lead barge toward the point and cut the corner as the tow boat swings to the outside of the curve. Keep the bow of your boat aimed at the approaching wave at all times. Do not try to pass the barge on a curve. They can take up the entire channel.
