🔍 Key Concepts

• Relative bearings vs. lines of position (LOPs) from fixed aids to navigation • How to plot bearing lines from known objects using a standard magnetic compass course • Checking which plotted intersection (fix) best matches the lat/long choices given

💭 Think About

• How do you convert the compass bearings you observed into lines that you can plot from each light on the chart? Think about whether you need to apply deviation/variation or if you can work directly with the given bearings for this exam-style problem. • Once you have three bearing lines from the three lights, where do they intersect on the chart relative to New Point Comfort Spit Light "2", Horn Harbor Entrance Light HH, and Wolf Trap Light? • After plotting, which of the four answer choices is closest to the intersection point of all three bearings?

✅ Before You Answer

• Verify that each bearing is plotted from the correct aid to navigation, using the proper side of the compass rose. • Check that the intersection point lies in a realistic spot (e.g., not on land if your vessel is known to be in navigable water, and in the expected general area of all three lights). • Compare your plotted fix with the given choices and confirm which latitude and longitude is closest to your plotted intersection before selecting.
