A dead reckoning position corrected for wind, steering error, and current is described as what?

• A. A DR corrected for effects of wind, steering error, and current
• B. A DR with no corrections
• C. An estimated position
• D. A DR computed from speed and time

Answer: (A)

Dead reckoning estimates where you are by starting from a known position and advancing with your speed, heading, and elapsed time. But real motion isn’t that simple: wind pushes the vessel off course (leeway), current carries you sideways, and steering error means your actual heading differs from the intended one. When you incorporate those influences into the dead reckoning, you’re adjusting the DR to reflect how the vessel actually moved over the ground. The resulting position is the dead reckoning position corrected for wind, steering error, and current.

If you didn’t apply these corrections, you’d just have an uncorrected DR. An estimated position would come from other methods (like celestial fixes or additional observations), not simply DR. And a DR computed from speed and time describes the calculation method itself, not the corrected state.
