Navigation General · Dead Reckoning
A vessel departs at 0600 steering 270°T at 10 knots. At 0900 the navigator plots a fix that places the vessel 6 nm south of the 0900 DR position. The 3-hour current effect shows a set of:
- A090°T
- B270°T
- C180°T✓ Correct
- D000°T
Explanation
The fix is south of the DR position, meaning the current has pushed the vessel southward. Set is the direction TOWARD which the current is flowing. Since the vessel was pushed south, set = 180°T.
