From your 1910 position, you set a course of 162°T at a speed of 14 knots. What is the distant off Race Rock Light when abeam of it?

🔍 Key Concepts

• Plotting a course line from a known position using true course and speed • Understanding what "abeam" means in piloting (bearing relative to your heading) • Measuring perpendicular distance (distance off) from a track line to a fixed aid to navigation like Race Rock Light

💭 Think About

• From your 1910 position, how do you lay out the course of 162°T on the chart, and what line does that create? • When a light is "abeam" of you, what is its relative bearing from your vessel, and how can you plot that from your track line? • Once you’ve found where the light is abeam on your track line, how do you determine the closest distance between that point and the light symbol on the chart?

✅ Before You Answer

• Be sure you are using true course (162°T) from the correct 1910 position plotted on the proper chart • Confirm your understanding that "abeam" corresponds to a 90° relative bearing to your heading, not true north • Measure the shortest (perpendicular) distance from your track line at the abeam point to Race Rock Light using the chart’s latitude scale for miles
