How to do the Rudder. A kayak technique to maintain the speed

The rudder is a fundamental stroke for whitewater kayakers. It allows to maintain the speed in a curved trajectory, saving energy and increasing the control of the boat.

Can you do this with wing blades?

I don't think it will work. To be honest the rudder is useful only with creek boats and we never use wing blades.
