A degree or two off course for a minute or so will trigger the command "Mind your helm" from a good OOD. I was "driving" in a heavy quartering crosswind one voyage and had to correct constantly. By the time I was relieved I had discovered that the only way to stay near to on-course was to hold a constant 3 degree rudder angle.
I was an icebreaker pilot. Not uncommon to steer the same course for an entire watch en route to Antarctica (by way of Australia in most instances). There were OODs with their heads up their keesters such that helmsmen managed to ‘make the loop’ on them.
