🔍 Key Concepts

• Radar or visual bearing and distance to a fixed aid to navigation on a chart • How to plot a single range and bearing to find a position • Reading latitude and longitude values precisely from a chart grid

💭 Think About

• On the chart, how do you draw a line that represents a true bearing of 303° from the light toward your vessel? Which side of the light will the line fall on? • How do you mark off exactly 7.1 nautical miles from the light along that bearing line, and then read the latitude and longitude at that point? • Once you have a plotted point, how can you compare its latitude and longitude carefully (to the tenth of a minute) with each answer choice to eliminate close but incorrect options?

✅ Before You Answer

• Confirm you are using true bearing, not magnetic or relative, and measuring it correctly from the aid to navigation symbol • Verify the distance scale you use (latitude scale or chart’s mileage scale) really corresponds to nautical miles near that latitude • Double‑check the minutes and tenths of minutes for both latitude and longitude when matching your plotted point to the answer choices
