Verlen Kruger is certainly an accomplished paddler, and designer. His statement that a canoe is the most efficient vehicle is not so accurate. A multi-speed bicycle can be much more efficient with a wide variety of payloads. Still he's got way more miles than I ever will. A canoe may be the most efficient when carrying over 600 pounds or so, but in terms of a 200 pound payload moved over a distance for a given amount of energy a road bike is the most efficient vehicle. Just taking down the dogma not the man.
