Take it from me, I can tell you first hand. I bought a BIG 19.5 foot AlumaCraft aluminum boat last year from a shyster kid on here that sold me a piece of junk that he knew was defective and needed major repairs. Anyway, that's another story. Bottom line is because of BOTH the lighter weight and the way this aluminum boat sat high in the water, I was blown around like a kite. Plus, that thing had so many craters on the bottom from running over stumps at Fork, and a pretty bad hook at the bottom of the transom from hitting stumps and denting in. I say don't do it, go fiberglass. But I also have a buddy that fishes Fork pretty much exclusively from a 19 foot Tracker, and does just fine. It also comes down to what you can find in your budget. But if it was me, I go glass and never look back.
