That's exactly what that extra tab does. Give it Yaw that is. I am sure welded tabs could create yaw. Some of the tab systems out there do have a unique shape to them to do that. The trick is finding out how much to give it. Depending on your hull shape, the tab shape would be different too. Yaw is used to clean up the wave a bit if needed. The adjustable flow 3 system allows the yaw to be varied depending on your ballast load and speed. Again, some of that "magic formula" . Or what SC would prefer to call Research! And it is.
