USCG Exam PracticeCourse to steer to compensate for current
The current vector triangle relationship is best expressed as:
- ✓ Course steered + drift vector = course made goodCorrect
- B. Course made good + drift vector = course steered
- C. Set + drift = course steered
- D. Course steered − set = course made good
Why A is correct
Bowditch Ch. 24 §2402 states the vector triangle as: course steered plus the drift vector equals course made good. To find the course to steer, this relationship is inverted: subtract the current vector from the desired course made good.
