Here is an ABC News video that provides further information...

--- The below taken from another forum ---
The collision happened at point A. One report had both vessels heading ENE, so that slight jog to the north prior to point A would explain the damage to Crystal's port side, and Fitzgerald's starboard.
From A to B would be where Crystal assessed what happened and conducted muster, damage control, etc.
At point B they returned to course consistent with their base course to keep in known water and point C is where they turned around to investigate the other ship and provide any assistance, if needed.
Point D, a return to Point A, is where they stopped at the initial collision point to investigate the Fitzgerald. (Note: Confirmation that the Fitzgerald waved off the Crystal when they returned.) And D through E is their departure from the scene, en route safe harbor.
But that track from point B to D is precisely what I would expect a lumbering vessel to do if they just had a collision and returned to the scene to investigate and/or assist.
Anyway, we'll know soon enough what happened, right down to the minute.
