USCG Exam Practice · Dead reckoning — DR plot maintenance
Set, as a component of current, is correctly defined as which of the following?
- AThe speed of the current expressed in knots
- BThe direction from which the current originates
- CThe direction toward which the current is flowing✓ correct
- DThe vector difference between course steered and course made good
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. Note that set is expressed as the direction of flow, not the direction of origin — a common source of confusion.
