So far as I can tell, ACX Crystal has a slow-speed diesel turning a fixed-pitch propeller, so no changing direction on the fly. It takes a lot longer than people think to kick in reverse, since that means completely shutting off the engine, waiting for it to finish turning, and blowing compressed air to start it again in reverse. Judging from the track, I doubt they even stopped the engine, let alone reversed it.

Thanks! Unfortunately, that removes one possible contributor to the violent vertical relative motion that occurred. (See my #292 -- just posted....)

Look at the violent "downward-smashing" that occurred on the Fitzgerald. Now, my guess is that the only thing that kept the Fitz from rolling over was its main deck embedded in the stem of the Crystal -- and the restraining presence of the Crystal's overhanging bow...
