🔍 Key Concepts

• Running fix with two bearings of a single object (advance the first line of position) • Using course and speed to find distance run between bearings • Basic triangle geometry between track line and the two bearing lines

💭 Think About

• First, compute how far the vessel travels between 0207 and 0226 at 13 knots. How many miles is that? • If you plot both bearings from the lighthouse and your track line, what kind of triangle is formed between your two positions and the lighthouse? • In that triangle, which side represents your distance off at the second bearing, and which side represents the run between bearings?

✅ Before You Answer

• Be sure you convert 19 minutes of time into hours correctly before multiplying by 13 knots • Check that the angle between the two bearings is the difference between 020°T and 042°T, not between your course and a bearing • Verify that your final distance off at the second bearing is longer than the distance you ran between bearings (that should help you eliminate some options)
