SNIP

I raised the point because it seems that the angle of attack may be harder 
to maintain than many people imagine.  In other words do we actually paddle 
in conditions that can reliably produce lift?

If my understanding of the stroke makes sense the paddle travels in an arc. 
The blade hits the water well away from the hull and slices down towards the 
hull. If the paddl blade travels in an arc I can see that it might travel 
normal to the boat's course. I could have this wrong so maybe some one who 
is an expert at this kind of thing can correct me.

Cheers
