so it's bad to bear away with the aft rudder. what about heading up?
do you think it's because of the proximity of the rudders to the hull?
the other possibility is that the rudder is already close to stalling just maintaining a steady course, and that to bear away it stalls completely. were this the case, i would think bigger rudders would help. the reported 5-10 degree AOA is consistent with this scenario.
counteracting weather helm with the front rudder can't be fast, as you'd be enhancing sideslip.
