🔍 Key Concepts

• Plotting an initial position and course line on the chart • Finding the location of Twenty-Eight Foot Shoal Lighted Buoy and measuring perpendicular distance • Understanding that Closest Point of Approach (CPA) is the shortest distance from your track line to the danger

💭 Think About

• After you change to course 086°T, what line do you actually draw on the chart from your 0130 position? • Where is the buoy relative to that new course line—directly ahead, off to one side, or behind you? • How do you measure the shortest distance between a fixed point (the buoy) and a straight line (your track) on a paper chart?

✅ Before You Answer

• Confirm you are using true course (086°T), not magnetic, when you plot your line of position • Make sure you locate the correct buoy (name and characteristics) on the chart before measuring • Use the chart’s distance scale (latitude scale) to measure the shortest, perpendicular distance from the buoy to your plotted course line and compare to the answer choices
