NAB,
Thanks, I understand what is being talked about now.
Given that there is reportedly damage to the stbd prop, and rudder, which I understand is offset to allow the shaft to be drawn if needed, it seems that a potential mechanism is that the fairing failed, and departed the coupling heading for the prop, which chewed-up the fairing and itself then fired some or all the remains into the rudder. The coupling itself may, or may not, be OK.
