Which term is the dead reckoning adjusted with known factors?

• A. Soundings on chart
• B. Datum on chart
• C. Estimated position
• D. Mean lower low water (MLLW)

Answer: (C)

Dead reckoning gives your position based on last known position, course, speed, and elapsed time. When you adjust that dead-reckoning position for known factors like currents, drift, and leeway, you arrive at an estimated position. This term reflects your best approximation of where you actually are between fixes. Soundings on a chart show depths, datum on a chart is the reference point for coordinates, and Mean Lower Low Water is a tidal datum; none of these describe adjusting DR with known factors. So the estimated position is the correct term.
