USCG Exam PracticeCourse to steer to compensate for current
A vessel's dead-reckoning plot accounts for which of the following factors?
- ✓ Course steered and distance run through the water onlyCorrect
- B. Course steered, distance run, and estimated current set and drift
- C. Course made good over ground and speed over ground
- D. Course steered, distance run, and leeway
Why A is correct
Bowditch Ch. 8 §801 states that a DR plot uses only course steered and distance run through the water, explicitly ignoring current and leeway. Incorporating current produces an estimated position, not a DR position.
