G'Day Peter, I believe you are correct and the crossection of the blade doesn't play much of a role in lift when the blade is set at an angle in the water. If the paddler were applying a horizontal push or pull to an angled blade the lift could be understood in terms of the blade being forced to move in the direction of least resistance to water pressure and therefore least work. If you had the blade angled up and facing forward the line of least resistance will either be forward and up (lift) or backwards and down (time to practice that roll) but would always have to be in the direction the paddle is moving.
