The swing can be reduced for less than half but not completely since the ridding sail has to catch wind to stop the boat from being pulled to one side, and then it starts a movement to the other side, over the wind till it catches wind again.
I can see that the design of that ridding sail is a very smart one. The boat in a frontal position to the wind is catching it on the two sails, on on each side and the boat should be kept stable on the spot without any lateral movement.
Someone have tried it?
