[Paddlewise] paddle analysis expectations

I have had the impression that students of paddle design are 
convinced, based on testimonials and math equations, that one sort of 
paddle will allow or encourage a more efficient stroke than can be 
accomplished using a longer or different paddle. 

In order to test the question, one must have expectations about the 
outcome of the tests. For me, the only issue of interest concerns 
whether or not one paddle or another allows the engine driving the 
boat at some constant speed for some fixed distance to do so with 
greater efficiency.  That means doing less work with one paddle than 
with another to achieve that constant speed over the fixed distance.

Do you believe that such a difference, if it exists, will be 
detectable? What % change in work is anticipated? Do you think this 
change will be statistically detectable (significant at the 95% level)?

Would you accept the possibility that there is no difference in the 
work required to push the boat as described above, but that under 
certain circumstances, sets of muscle better suited for sustained 
paddling are brought into play with certain paddles, which causes the 
perception that "less work" is being required to drive the boat?

I would appreciate a clearer discussion about the nature of the 
questions being proposed for testing.

Thanks,
Chuck Sutherland
