Question 1 of 27070

Your 0530 position is LAT 41°04.9'N, LONG 73°01.1'W. What is the course per standard magnetic compass to a position 1.0 mile south of Twenty Eight Foot Shoal "TE" buoy?

🔍 Key Concepts

• Using the chart to find Twenty Eight Foot Shoal "TE" buoy and plotting a position 1.0 mile south of it • Measuring the true course from your 0530 position to the destination point using parallel rulers or a plotter • Converting from true course to standard magnetic compass course (psc) using variation, deviation, and the correct sign conventions

💭 Think About

• From your 0530 position, how do you plot the line to a point 1.0 NM south of the buoy, and what tool do you use to read the true course off the chart? • Once you have the true course, what is the correct sequence of applying variation and deviation to end up with a standard magnetic compass course? • Are you using the proper annual rate of change for variation from the compass rose date, and the correct deviation value from the deviation table for the closest heading?

✅ Before You Answer

• Confirm the exact charted position of Twenty Eight Foot Shoal "TE" buoy and carefully mark the point exactly 1.0 NM due south (not SE, SW, etc.) • Double-check your true course reading from the chart before any corrections—small angle errors can change the multiple-choice option • Verify the current variation from the compass rose and the proper deviation for that heading from the deviation table before choosing the final psc answer
