I looked at the online track and it appears the Crystal heading south, made a quick turn to the right (probably trying to avoid the Fitzgerald approaching from the left according to some reports on the track) and avoiding a straight on "t bone" (this usually (not always) means the Crystal had the right of way being to the starboard side of the Fitzgerald, meaning, the Fitzgerald should have passed in back of the Crystal and not in front, slowing if needed to let the Crystal pass). After the tight right, the Crystal steered to the South then turned back in a u turn to the site of the collision where it seemed to slow and turn where the Fitzgerald was, then it made another turn to get back heading South. Question is why the Crystal turned back to the site of the collision, but did not remain there. Also, how was it that the Fitzgerald crossed in front of the Crystal which was to the starboard side of the Fitzgerald which usually means the Crystal had the right of way.
