Chart Navigation & Plotting · Set and Drift
Your intended track is 090° at 10 knots. A current sets 180° at 2 knots. Ignoring leeway, your track made good will be deflected toward the:
- ANorth of the intended track
- BSouth of the intended track✓ Correct
- CAlong the intended track but slower
- DReverse of the intended track
Explanation
A current setting 180° (toward the south) pushes the vessel south of an easterly (090°) intended track. To make good the 090° track the navigator must steer slightly north (into the current) to offset the set.
