I prefer glass. I live on the Oly Pen. and fish the Duc all the time. I have a 16 ft wide bottom heavy duty glass boat and I guarantee you that we float when most aluminum boats won't because of low water. They don't stick on the rocks, they're quiet and they don't jar you so hard if you slam some rocks when going down rocky chutes in low water. I've had friends in my boat that figured I had all but ripped up the bottom after a trip down the Duc in low water but later showed them nothing but scratches. My only complaint is putting a heater in it in the winter. Better be careful or burn your boat. Hope this helps.
