Thanks for the discussion on stall but I already knew that. What I hoped to 
read was how you could prove you could detect and respond to stall in your 
paddle stroke.

Does the magnitude of the effect help you in the airplane? I too have 
experienced it in an airplane and it was damned dramatic. Given the forces 
etc. on a paddle it doesn't sound equivalent.

Can most feel it? How do you know? Once you lose lift how do you separate 
the sensation of increased drag from the loss of lift particularly when you 
may have little or no decrease in boat speed?

Always? (See below)

My point exactly but without the optimism. Keep in mind that paddlers using 
GP paddles and a drag oriented stroke can, at cruising speeds at least, 
keep up with other GP using paddlers supposedly using lift oriented strokes. 
How do you tell what part of the stroke is stall or lift if the resultant 
thrust remains the same or similar?

Most know that GP paddles can stall . I asked if you could prove that you 
could both recognize it during the stroke and make the appropriate 
adjustments to the angle of attack to stop the stall which hasn't been 
forthcoming.  Your answer didn't help much.
