This is a guess, but I think the further backward you move the axis, the more your rudder will cross the centreline and produce drag instead of turning force. Secondly, to the degree that you move it backward it will also make it more difficult to centre when you let off the pedal/tiller pressure.

: Anyone have literature or experience on the ideal location for the rotation
: axis of a rudder? I often see overstern type rudders with the rotation far
: in front of the rudder. I am making an understern racing style foil shaped
: rudder and was interested to know if the shaft should enter as far forward
: as it can fit, as I sometimes see rudders like this that have the shaft
: further toward the center of the rudder. (My K1 racing boat rudder has the
: shaft delicately attached near the leading edge of the rudder).

: any 'rules' on this?
