🔍 Key Concepts

• Range to a charted object and how to plot a 4.5 nm arc from a known point on the chart • How to convert a per gyro compass (pgc) bearing to a true bearing using known gyro error or variation/deviation data from the exam booklet/chart • How to use a single bearing + single range to fix a position on the chart

💭 Think About

• On the chart, where is Block Island North Light and where is Sandy Point located, and what does a 4.5 nm range from Sandy Point look like when plotted? • Once you convert 139°pgc to a true bearing, what line do you draw from Block Island North Light, and where does that line intersect the 4.5 nm arc from Sandy Point? • After plotting the intersection, which of the four answer choices most closely matches the latitude and longitude of that point?

✅ Before You Answer

• Make sure you are using the correct symbol/location for Block Island North Light and Sandy Point on the exam chart • Confirm you converted 139°pgc to true correctly before plotting the bearing line • Read off latitude first, then longitude, and be careful about tenths of minutes when matching to the answer choices
