I downloaded graphs showing the speed of the ACX Crystal over a 24 hour period surrounding the time of the wreck. I posted them on a previous thread. I can’t access them right now, but will try again later.
The Crystal’s speed was erratic, going up and down. Then it went steadily up to about 19.3 knots, where it peaked at about 2:00 AM local time on 6/17/17. The graph shows a sudden sharp decline in speed right then. It appears the wreck occurred at about 2:00 AM. Not 1:30 or 2:30.
