At 1020 your position is LAT 41°11.0'N, LONG 71°50.0'W. You are on course 056° per standard magnetic compass at 9.2 knots. At 1112 your position is LAT 41°15.9'N, LONG 71°41.7'W. What were the set and drift?

Question 1 of 27070

🔍 Key Concepts

• Dead reckoning (DR) track vs. fix positions on a chart • How to compute course and distance made good between two fixes • Definition and direction of set (current direction) and drift (current speed)

💭 Think About

• From the first fix, plot your DR position at 1112 using your ordered course and speed. Where should you be if there were no current? • Now plot the second fix at 1112. What is the direction (true bearing) and distance from the DR position to the actual fix? • How do you convert that distance over the elapsed time into knots, and what does the direction of that line represent in terms of current?

✅ Before You Answer

• Be sure you convert elapsed time (1020–1112) into hours and decimal hours correctly before finding speed in knots. • Confirm that your DR track uses the given standard magnetic compass course corrected to true before plotting on the chart. • Make sure you express the final set as a true direction (0°–359°T) and drift as speed in knots, then compare both to the choices.
