I love this boat! I have paddled it on whitewater up to class III with ease and find that after the first few strokes to get it moving I can zip right along on large open water. I paddle this boat every day. I would love a faster boat on the lakes but I know I would sacrifice the maneuverability of my guide for the rivers. The key word is versatile! From calm ocean (Acadia, Maine) to class III this boat does it all!
