🔍 Key Concepts

• Three-bearing fix using visual bearings plotted from known lights • Converting psc (per standard compass) bearings to true bearings using deviation and variation from the chart / deviation table • Carefully checking which side of each light your LOPs (lines of position) should fall on, based on the relative bearing and your course

💭 Think About

• How do you convert each of the three psc bearings into true bearings before plotting? What information on the chart and in the deviation table do you need? • Once you plot the three true bearings to the three lights, do they form a tight triangle? Where within that small triangle would you select your fix? • After you identify your fix on the chart, how can you read the latitude and longitude accurately enough to distinguish between options only a few tenths of a minute apart?

✅ Before You Answer

• Be sure you apply compass error (variation + deviation) with the correct sign when going from psc to magnetic to true • Verify that the bearings are FROM the vessel TO the lights, so you must plot reciprocal bearings (from the lights to you) on the chart • Double‑check the latitude and longitude scales and make sure you are reading minutes and tenths of minutes correctly before matching to the choices
