USCG Exam PracticeEstimated position from current set & drift

A DR plot projects the vessel's position using which two factors only?

  1. A. Course steered and leeway
  2. B. Course made good and current drift
  3. ✓ Course steered and distance run through the waterCorrect
  4. D. Set and drift for the elapsed time

Why C 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. Applying current corrections produces an estimated position, not a DR position.
