i recently sold my prowler 13 - reason being was that I moved away from tidal waters and into the mtns were rocky rivers are the norm. The scuppers on the prowler had a bit of protrustion on the bottom that was fond of catching on rocks in shallow water, especially shallower rapids and thsi would certainly eat a hole in the scupper in short order. B/c of this, many people that I know that fish kayaks on rivers have went with the Tarpon. 100 and 120s are popular because they offer good tracking and manueverability on flowing waters.
