Why is that so I wonder? If the water would say freeze for the moment the
blade was in it, the paddle would still work,
but you won't need the blade (area) anymore?
The reason I think we need blades on our paddles is because the paddle does
(unfortunately?) move through the water,  and what we need is 'resistance'
against this movement to go forward?
Main question for me is, how big and what form a blade you need to paddle well.
For freestyling a bit I prefer a rather large blade, because this involves
a lot of accelerating and stationary strokes and my stroke rate is generaly
relatively low then. For touring, I prefer blades as small as possible
letting me paddle me as easy as possible on my usual cruising speed, where
I take in a large account of upwind paddling as the most important factor,
since this is indeed the most tiring condition to paddle.
I seem to prefer low aspect ratio blades, because I have the _feeling_ that
they deliver just a bit more performance at an easier for me to maintain
high stroke rate. But there are so much variables around,
I will still keep an open mind for any method to improve on what I do.
(That's were PaddleWise is doing very well I think?!!)
And I have discovered that even seemingly little different boat designs
ask (me) for quite different stroke rates to paddle well. So I have
to do more field tests with differenty paddles, which is good anyway
because I can do some more paddling then...
