I have a line a twenty foot aluminum john with trailer and old evinrude. The boat is welded together out of two. It is not real wide maybe 42" in the bottom. The guy wants two hundred for it. Is this boat to long or what would be the advantages or disadvantages. What might I do with this long of a boat.? Lake or river, ruff water or slough? Any thought or exsperiences greatly appreciated. t- bones got me excited on his new rig!
