  6. Over the next few minutes, the first pilot ordered various rudder and engine commands in an effort to steady the vessel in the channel as the tanker exited the turn.
  7. As the Eagle Otome closed with a starboard bank of the waterway, the pilot ordered a sequence of increasing starboard rudder commands and an increase in engine speed to preempt the anticipated sheer to port.
  8. At this position, the first pilot asked the second pilot “is she gonna come back?”
  9. The second pilot responded “might”.
  10. As the Eagle Otome approached the bridge the first pilot had hard starboard on the rudder for almost 90 seconds with a half ahead bell in order to break the sheer to port.
  11. Once through the bridge, and although on the left side of the channel, the first pilot ordered several mid-ship and port rudder commands in an attempt to counteract the sheer to starboard.

  21. Twelve seconds later the first pilot instructed the master to let go the starboard anchor.
  22. Twenty seconds later, the first pilot ordered the engine full astern.
  23. The towboat master radioed the Eagle OtomeDixie Vengeance, inbound ship looking okay?”
