At 0000 you fix your position and change course to 270°T. At 0030 you again fix your position, and it is 0.5 mile east of your DR. Which statement is TRUE?

Correct Answer: Option D — The set is 090°, drift 1.0 knot.

Per Bowditch set and drift calculations, traveling 270 degrees true over 30 minutes with a position 0.5 mile east of the dead reckoning position indicates a current setting directly opposite into 090 degrees at 1.0 knot.
