🔍 Key Concepts

• Converting compass bearings to true bearings using the correct deviation and variation from the exam’s plotting sheet or table • Running fix by three LOPs (lines of position) from simultaneous bearings • The relationship between your ship’s heading (087° psc) and each relative or compass bearing to plot accurate LOPs

💭 Think About

• What corrections (if any) must you apply to a standard magnetic compass (psc) bearing before plotting it on a chart that is in true north? • Once you have three corrected bearings, how do you use them to create three LOPs and find the common intersection point? • After plotting your position, which of the four answers is closest to the intersection point you obtained on the chart?

✅ Before You Answer

• Verify you are using the correct variation and deviation values from the exam’s plotting sheet for 087° psc and for bearings in that area. • Confirm each line of position is drawn from the correct charted object (Falkner Island Light, Horton Point Light, Mt. Sinai Breakwater Light) with bearings measured from the object toward your vessel. • Make sure your plotted fix lies reasonably close to your track line of 087° and in a realistic position relative to the three aids to navigation.
