I saw another track that had the collision where the Crystal’s last starboard turn is.
The Fitz was positioned going in the opposite direction.
The Crystal turned slightly to port as did the Fitz, crossing the bow of the Crystal.
It was as if the ships decided to pass starboard to starboard instead of protocol port to port.
Just guessing, without seeingg depth charts, etc I think the Crystal realized it was on the wrong track heading for trouble, backtracked looking for the shipping lane.
Even if the Crystal wanted to intentionally ram the Fitz, the Fitz should have been able to stay clear.
In 1956 the Andrea Doria and the Stockholm were each aware of the other as their radars picked up the presence of the other ship, though fog prevented visual sighting until the last minute. Misunderstanding the two ships’ intentions lead to the collision. Perhaps something similar happened here.
