Some time after writing that article I built a new, larger tank for testing
paddles. I got different results. In consultation with some people at the
National Research Center it was suggested that the tank walls were too close
to the test samples which invalidated the tests. I am still not convinced
that I have the complete answer on this one (or a lot of other things) but
the tests in the larger tank would seem to be more reliable and suggest that
narrow paddles do not have higher drag ratios. Canoesport Journal was no
longer in existance to print a revised artilcle. I hope to update things
once a new version of my book comes out someday.


Cheers,

John Winters
