Whirly-Bird:

The whirly-bird is basically a stall and a pirouette mixed together. Once you have mastered the stall, sink the blades into the water and stand up slightly on the foot blocks, just past your usual stall position.

Drive your blades into the water and pull in one direction and rotate your head in the direction of the drive.

The boat will then rotate on its vertical axis. You can change direction at any time by using the drive from your blades!
