Sorry, I know it's been several days since your post, but I did not imply the Fitz was turning to starboard. It seems that if she turned at all, it would have been to port.
Of course, if the Fitz somehow thought the Crystal's bow was it's stern, and tried to turn in behind it, that could explain a starboard turn. Very unlikely, in my opinion.
No need to apologize. I was just noodling. There is video on youtube of a Burke turning to port at full speed and it behaves exactly as you stated. I think we need to keep an open mind about this incident until the report is issued and then a skeptical mind is in order.
