USCG Exam PracticePlot true course and distance between two charted points
A vessel departs a fix at 0800 and steers C 270, S 10. No new fix is obtained. At 0900 the navigator plots a position using only course steered and distance run through the water. What type of position has been plotted?
- A. Estimated position (EP)
- ✓ Dead-reckoning (DR) positionCorrect
- C. Fix
- D. Running fix
Why B is correct
A DR position is projected from the last fix using only course steered and distance run through the water, with no correction for current or leeway. It is plotted as a dot with a semicircle and labeled with the 24-hour time. (Bowditch Ch. 8 §801, §802)
