If I'm interpreting the photos correctly the two rudder stocks seem to be bent approximately equal and opposite. The most likely cause is simply the considerable force caused by the leverage during sailing. I would expect them to be bent toward midships if this is the case (I think this is what the photo's show). Depending on the grade of stainless used they should bend back into shape fairly easily but I would then examine them very closely for any signs of tiny cracks. A marker pen and some petrol to wipe it off leaves the stain in the cracks and they show up nicely.
