USCG Exam PracticeEstimated position from current set & drift
A DR plot ignores which of the following factors when projecting a vessel's position forward from the last fix?
- A. Course steered
- B. Distance run through the water
- ✓ Current set and leewayCorrect
- D. Speed through the water
Why C is correct
Bowditch Ch. 8 §801 states that a DR plot projects position using only course steered and distance run through the water, explicitly ignoring current and leeway. The EP, not the DR position, accounts for estimated current.
