Think it's possible that a control system failure made the rudder go hard over?

Hope so, but everything worked fine all way back to port and they can find no problems now.
Even in rudder hard over it would still take several football fields to turn.
These ships have redundent steering systems. For a rudder to go hard over like that, a steering rod would have to snap, or the rudder post would have to fail. I investigated a 36 inch rudder post failure on a super tanker once. But, on a new vessel, I don't think that was the issue. These vessels have gyro-stablizers, stabilizer fins, and I believe quick ballast water movement to provide passengers with a puke free enviornment. My best guess at this point is that the stabilizers may have malfunctioned, not the steering system.
Or maybe it hit something too.
Could be a sunken wreck the cruise ship bottomed out on.
A few lines of code and the stabilizers, rudders, thrusters and main screws all push towards the same goal...
