Then I have a question: When one slices the paddle verically down a few 
inches into the water, absolutley perpendicular to the boat, then flatten the blade 
so that the entire width of the blade is popped upwards, one will get forward 
motion. Is that not lift generating forward motion?

We did that scenario at the recent greenland symposium here on the west 
coast. we sliced the blade down just a few inches, flattened it and popped it back 
up. No rotation, no sweeping, nothing. We did it many times on each side, 
achieving about a knot, maybe more of speed.

Now, as soon as the E=MC Sqared formulas start into the thread my eyes glaze 
over. I'll need some explanation in addition to that. I'm just curious if we 
were practicing some other form of motion than lift or lift does generate 
forward motion.
