The paddle assembly consists of three parts; a shoulder harness, a paddle, and a connector between the two. The shoulder harness is a simple cap that is worn on the shoulder of the sound side of the body and is anchored to the torso by straps that go from the back around the torso and buckle in the front. The paddle is made of carbon fiber, uses a standard paddle blade and has a modified shaft. The shaft attaches to the top of the shoulder of the user at the shoulder cap.
To use the paddle, the user grasps the vertical aspect of the paddle shaft with the sound-side hand and uses torso rotation to power the strokes.
Now that Cindy has received the seal of approval from the patent office, hopefully this will go to manufacture and be available on the market soon.
Below is some footage from Cindy's website of the paddle in action.
