USCG Exam PracticeCourse to steer to compensate for current
According to the vector triangle for current correction, which relationship is correct?
- ✓ Course steered + drift vector = course made goodCorrect
- B. Course made good + drift vector = course steered
- C. Set vector + course made good = drift
- D. Drift vector − course steered = course made good
Why A is correct
Bowditch Ch. 24 §2402 defines the current vector triangle as: course steered plus the drift vector equals course made good. Inverting this relationship allows the navigator to solve for the course to steer to achieve a desired track over ground.
