Chart Navigation & Plotting · Set & Drift — Vector Triangle
In a current triangle used to find course made good and speed made good, the three vectors are the vessel's water track (course/speed), the current (set/drift), and the:
- AWind vector
- BTidal range
- CGround track (course and speed made good)✓ Correct
- DCompass error
Explanation
The vector sum of the vessel's movement through the water and the current vector gives the resultant track over the ground — the course made good and speed made good.
