I know a lot of paddlers see surface effects and then make assumptions about what's happening, but that's not the same thing as seeing what is happening." I knew someone would point this out. You can't see the flow, if it is working right, but you can see the vortex, deep in the water, you can see the turbulence created when imperfections on the leading edge trip the flow, you can see the air sucked down the blade if it ventilates, and you can see the immense amount of turbulence when the blade stalls. No doubt these are gross effects, and we would be better off studying this stuff at the invisible stage, but this whole problem is still at the gross effects stage. It is good enough to get the hang of how to use the paddle.
