🔍 Key Concepts

• Relative bearing change and when a light is "abeam" (i.e., 90° on your starboard or port side) • Using time and speed to find distance run between bearings • Constructing or imagining a simple relative-motion triangle with your course and the observed bearings

💭 Think About

• How does the bearing to the light have to relate to your ship’s course when the light is exactly abeam? Think in terms of a 90° angle. • From 0255 to 0312, what distance have you run at 19 knots, and how can you use that with the two bearings to estimate when you’ll reach the abeam position? • If you sketched this to scale on a plotting sheet, where would the light lie in relation to your track when the bearing change stops increasing toward your bow and becomes 90° off your beam?

✅ Before You Answer

• Be sure you are clear on what abeam means in terms of relative and true bearings. • Convert the time interval between observations to hours correctly before using speed-distance calculations. • Check that your final time is after the second bearing and that the distance off is reasonable compared with the distance run between 0255 and 0312.
