What did Shinano do? She slammed back and forth against the other end of the dock 2 or 3 times, with her bow taking the brunt of the damage.

I can only imagine what that must have looked and sounded like

What disciplinary action was taken with the docking officer? That I don't know. More than likely he was "invited onward".
