if I told you that
rudders were important tools of boat handling, but not to be considered
for steering, rather for "thrust vectoring", when maneuvering around a
dock, etc., when kicking an engine ahead, both positive and negative
...... would you understand what I was saying?

I would know you are bull****ting, for pulling water over a rudder with a prop
does not -- and can not under the laws of physics -- affect the direction a
boat is moving.
