🔍 Key Concepts

• Converting compass bearings to true bearings using deviation and variation (psc → psc corrected → magnetic → true) • Plotting lines of position (LOPs) from known objects (lights) on the chart • Checking whether the geometry of the three LOPs matches the approximate area of the multiple‑choice positions

💭 Think About

• First, think about how you turn a standard magnetic compass (psc) bearing into a true bearing you can plot on the chart. What correction sequence do you normally follow on license exams? • After converting each bearing to true, where do the three LOPs roughly cross on the chart in relation to New London Ledge Light, Little Gull Island Light, and Saybrook Breakwater Light? (Inside Long Island Sound, closer to which shore?) • Compare that approximate intersection area with the four choices: which latitude/longitude falls in the same part of the chart as your plotted fix?

✅ Before You Answer

• Verify you are using the correct sign and order for deviation and variation (don’t accidentally apply east/west the wrong way). • Verify that the bearings are FROM the vessel TO the lights, so your plotted LOPs should pass through the light symbols using the converted true bearings. • After plotting, verify that the shape and relative angles between the three LOPs on your chart look similar to the angles between the three compass bearings given (they should be consistent).
