USCG Exam Practice · Dead reckoning — DR plot maintenance

- ADrift
- BCourse made good
- CSet✓ correct
- DLeeway
Why C is correct
Bowditch Ch. 23 §2302 defines set as the direction toward which the current is flowing and drift as the speed of the current. These two terms are frequently confused on the exam; drift is a speed, not a direction.
