Some comments on statistical approach....not being a statistician nor ever 
playing one on TV....

This would be an interesting endeavor (and I'd love to see the results and 
I'd certainly be willing to participate) but it strikes me that the amount 
of variation due to 'other' sources (conditions, boat/hull design, stroke 
mechanics, paddler skill/condition/mood that day, etc) would likely swamp 
out any detectable variation due to paddle.  No good way to control those 
other sources of variation - and they are going to be HUGE relative to the 
paddle variation (for instance, I'm sure there have been lengthy exchanges 
about hull designs in the past and my guess is hull design would affect 
these times much more than paddle).  I suppose it is a bit like testing 
tires by having them run on 100 different cars....with no control on 
make...1 pickup, 1 Porsche, 1 Chevy Vega, 1 Ford Pinto, 1 Ferrari, etc

I've seen guys that could likely blow my doors off paddling with only a 
Q-tip...wouldn't matter what paddle you gave me...unless it had "Honda 7.5 
hp" stamped on the side....  ;o)

Just my 2 cents - FWIW,
K
PS:  Just thinking out loud but maybe one way to somewhat capture this 
would be to have each paddler use some standard, widely available paddle, 
then also do this with their own, and use a difference in times as some 
measure - and run a couple of trials each - two days, each day do one run 
with standard paddle first, then vice versa.  Not sure this would 
adequately capture any/enough of that 'other' variation - but it might.  Of 
course, you have to find a standard paddle that everyone can get their 
hands on....probably no small task.
