"Only if the angle of attack is zero degrees. Any airfoil will generate lift if it has a positive angle of attack." Thanks Dave, and for the Wikipedia reference, which I have now had a chance to read. Sticking point (punny about that) in my mind is that an airfoil is assymetric in section, and a greenland paddle is symmetric. So why would a GP act like an airfoil and generate lift in a direction away from the back of the blade? Or is that not what is meant when a GP is said to generate lift? I understand a wing paddle, which is a foil, generating lift away from the back of the blade, but a GP? *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
