USCG Exam PracticeEstimated position from current set & drift
A DR plot projects a vessel's position using which two factors only?
- A. Course steered and set of the current
- ✓ Course steered and distance run through the waterCorrect
- C. Course made good and speed over ground
- D. Course steered and drift of the current
Why B 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. Current factors are applied separately to derive an EP.
