Question 1 of 27070

At 0700, Falkner Island Light bears 023°pgc, and the range to the south tip of Falkner Island is 7.1 miles. What was the course made good since 0615?

🔍 Key Concepts

• Relative motion on a plotting sheet between 0615 and 0700 • Using a bearing and range to fix a position • Converting between pgc (per gyro compass) and true (T) courses, if a gyro error or variation is given elsewhere in the problem set

💭 Think About

• From the vessel’s known 0615 position, how would you plot the 0700 line of position from Falkner Island Light using the 023°pgc bearing? • How does the 7.1‑mile range to the south tip of Falkner Island at 0700 help you pinpoint the vessel’s exact 0700 position on the chart or plotting sheet? • Once you have the 0615 and 0700 positions plotted, what simple geometric method lets you determine the course made good between these two points?

✅ Before You Answer

• Confirm you are measuring the bearing from the light to the vessel or from the vessel to the light in the correct direction on the chart. • Make sure the 7.1‑mile range is drawn along the correct line from the south tip of Falkner Island, not from the light itself. • After plotting both positions, carefully measure the true course from the 0615 fix to the 0700 fix, and verify it falls close to one of the multiple‑choice answers.
