Although there is no question in my mind as to the outcome, the way to prove this is not through mathematics, but through measurements. By measuring the force x distance applied to different paddles when propelling a particular boat at a particular speed, one could answer the question definitively. Unfortunately, the instrumentation required for that would be fairly complex, and may inhibit normal use of the paddles. Another way of measuring it is through oxygen uptake of the paddler under controlled conditions (same paddler, same boat, and same speed). That would factor in not only the work applied to the paddle, but any secondary/ergonomic effects on the paddler. I think the instrumentation is simpler, and it takes all effects into account. Is anyone on the list familiar with current techniques for measuring oxygen uptake? Steve Brown I agree, though, what we need is a comprehensive source of paddle physics and hydrodynamics backed with lab data. AFAIK, this doesn't yet exist. Some very ambitious soul has to go thru the mountains of publications and accumulate and summarize the info that's out there.
