Got a similar story, this was in the early 90’s on the West coast.
The midnight to 6 watch was the mates watch and he was pretty proud of the speed he had been making for the last several hrs. until the Captain came on watch. After hearing all the good news about the speed they were making the Captain without looking back or look in the radar says “when did you lose the barge” the shocked look on the mates face was priceless.
