drifting

For example, the Gulf Stream has a velocity of almost 5 knots. If you set a course, say for the Carolina coast near Chareston of, at, say, 270 degrees. You could hold that course, but by crossing the gulf steam at 12 knots and holding your course, you would be 30 miles/12 knots x 5 knots=12.5 miles North of Charleston, and that doesn't consider the effect of wind and waves of the boat. Using way-points solves the problem with periodic (in real life) corrections.
The Arctic Stream is even faster
I think the periodic drifting is a good compromise in the game.
This is no longer a problem with GPS navigation.

Steve is right, and has it right (as usual).

Remember that Course and Heading are not the same thing.

One holds a specific Heading while conducting a torpedo attack.
The only Course of interest, is that of the target(s).
