Navigation General · Currents
A vessel's Course Made Good (CMG) is 080°T and Speed Made Good (SMG) is 12 knots. The vessel is steering 090°T at 14 knots through the water. The current's SET is most likely:
- AEast
- BWest
- CSouth
- DNorth✓ Correct
Explanation
The vessel is steering 090°T but making good 080°T, meaning the current is pushing the bow to the north (left of intended course). Therefore, current set is northward. The vector triangle shows the ship's water track vector plus the current vector equals the ground track vector.
