USCG Exam PracticeCourse to steer to compensate for current
A dead-reckoning plot projects the vessel's position using which of the following inputs?
- ✓ Course steered and distance run through the water onlyCorrect
- B. Course steered, distance run, and estimated current set and drift
- C. Course made good and speed over ground
- D. Last fix position corrected for leeway and current
Why A is correct
By definition, a DR plot uses only course steered and distance run through the water, explicitly ignoring current and leeway. When current is factored in, the result is an estimated position, not a DR position.
