As you can see in the picture, the Flow 3.0 plate basically adds an actuator ON the main plate. As the main plate goes down, the secondary actuator moves the inside plate down also. This creates additional side force of yaw to the boat which in turn pushes the rooster tail away from the surf side. By doing this, you can run a boat even more level which again adds the maximum amount of displacement, giving the largest wave possible. It also greatly improves transfer ability. With the Flow 3.0 plates, you can basically run the boat with completely level ballast side to side and the plate alone can change the roll enough and the second plate cleans up the wave to allow transfers back and forth without changing ballast or passenger location.
