🔍 Key Concepts

• Line of position (LOP) from bearings plotted from known charted objects • How to convert a per gyro compass (pgc) bearing into a true bearing before plotting • The intersection of two correctly plotted LOPs gives your fix (position)

💭 Think About

• On your chart, where would you place Tue Marshes Light and York Spit Swash Channel Light "3" before drawing any lines? • From your vessel, does a bearing of 264.5°pgc to Tue Marshes Light mean the light is to your right or left when looking at true north on the chart? • After you convert both bearings to true and plot the two LOPs from the correct objects, which of the answer choices lies closest to their intersection?

✅ Before You Answer

• Confirm how your exam reference converts gyro (pgc) to true (apply gyro error correctly and in the right direction). • Verify you are drawing each LOP through the aid, then extending the line in the correct direction opposite the bearing (remember: you stand at the aid looking back at the ship). • Check that your final visual fix is in a reasonable location relative to both lights (distances and general orientation should make sense).
