No thom, it's not that type of system, thats what I thought it was.
This is just a fine tuning system to balance the boat.

Ever seen an articulated rudder? Similar except that it's controlled by a
linkage to the rudder post that makes it turn the same way as the rudder
only a little bit further. More efficient steering.

Using a trim tab just to offset the force on the rudder blade from normal
sailing doesn't make sense to me. It just adds drag. It would be better to
adjust the sails so as not to have so much helm, or to add balance area to
the rudder blade forward of the pivot point (rudder post).

The Flettner "trim tab" improves stall characteristics of the rudder.
