Navy = Master-helmsman. Longest period of time at refueling was 4 hours. That was for a Battleship. BB-62. The Master-helmsman was given a course, once on that course, it was paramount to keep that course without error. The Master-helmsman was second only to the Captain on the bridge during replenishment evaluations. Took me many months on the helm to learn the ship’s personality.

This is a good video for knowing tanker and seamans job. I have experience of tanker operation on the sea and now working on the vlcc terminal with loading master.
