🔍 Key Concepts

• Use the three bearings at 0615 to plot a fix and compare it with your DR (dead reckoning) position from 0530 • Current is found as the vector from the DR position (no current assumed) to the actual fix (with current) over the elapsed time • Set is the direction the current is flowing TOWARD; drift is the speed of that current in knots

💭 Think About

• What is your DR position at 0615 if you advance your course and speed from 0530 with no current? Where is your plotted fix at 0615 from the three bearings? • When you draw the line from the DR position to the fix, in which direction is that line pointing, and how far apart are the two points? • Given the time interval from 0530 to 0615, what current speed (drift) does that distance between DR and fix represent?

✅ Before You Answer

• Verify your three LOPs (lines of position) from Stratford Point, Falkner Island, and Branford Reef all intersect properly at 0615 to give a clear fix • Carefully measure the distance between the DR and fix with your dividers; convert that distance over 45 minutes into knots using ( \text{Speed} = \frac{\text{Distance}}{\text{Time}} ) • Make sure your set angle is measured FROM the DR TO the fix and compared correctly with the two possible directions given (263° vs 083°)
