Is this not the way "Wing"paddles work?. By creating a paddle with a blade
cross section "Wing" shaped, and initiating the paddle stroke with a motion
at right angle to the axis( is this the right word? my physics are
rudimentary at best!) creates "lift". This lift transfers " paddle slippage"
from along the axis to "slippage" at right angles to the axis. When you plant
one of these paddles in the water and pull on it it dose not want to pull
straight back through the water, it wants to move away from the boat. So the
spot were the paddle enters the water is very close to were it is withdrawn,
at least along the axis. Using a wing feels like sticking your blade in
concrete, you can pull your self almost to the spot were you stuck the paddle
in. All this dose use a different paddling technique. Well this is my
interpretation of how a Wing paddle works, pleas correct me if I'm wrong!!
