[Paddlewise] Clarification?

To my knowledge no one has ever provided proof that one could apply steady 
state theory to paddles. Simply quoting steady state theory does not qualify 
as proof.

Until some one can provide actual test data to support the assumptions that 
rthe esult of steady state flow is sufficently close to the pulsed flow of 
paddles then we cannot lend much credence to it.

I suspect that a lot of the confusion comes from assuming the objective is 
high lift as opposed to high thrust per unit area.  If we change the 
question from How do we generate more lift? to How do we generate more 
thrust we may get another answer.

Another problem we should condsider in the quest for high lift has to do 
with the difficulty in maintaining any angle of attack through the water 
much less the ideal angle of attack. Can paddlers actually achieve and 
maintain the desired angle of attack? How does one compensate for the 
variability in angle of attack due to the ever changing flow direction in 
waves? (with the wave at the crest, vertical down on the front face, against 
the wave direction in the trough and vertically up on the back and, of 
course, everything in between)
