Ok so I took my hunter 410 out for the first time since rebuilding my rudder. 4.7 knots under power and it starts to pull to port. Sailing at 5.4 and no pull, didn’t get her faster than that on that given day. Boat pulls and turns to port, wheel turns counter clockwise, rudder is oriented with the leading edge pointing starboard and trailing edge pointing to port. I believe it is out of symmetry. Any thoughts as to which side would need to be reduced? Port or Starboard ?Any ideas as to how to check symmetry? Any thoughts as to which is most important, trailing edge or leading edge and what tolerances we are talking about. I am a little confused on foil theory and what the pull to port would indicate with regards to the shape and which side to reduce ?
