🔍 Key Concepts

• Running fix using multiple bearings of a single object • How a change in true bearing shows whether you are passing north or south of track • Relationship between DR (dead reckoning) track, intended track, and position relative to a light

💭 Think About

• Sketch your 1155 DR position and lay down your intended track 282°T. From that track, imagine where Falkner Island Light lies relative to you on the first bearing of 318°T. Which side of the bow is it on? • Compare the first bearing 318°T to the second bearing 355°T. Is the bearing moving clockwise or counter‑clockwise, and is it moving toward the bow or toward the beam? What does that say about which side you are passing the light on? • Once you’ve decided which side of the light you are passing, think: does that side put you north or south of your intended track in this area of the coast?

✅ Before You Answer

• Be clear that the bearings are from your vessel to the light (not the other way around). • Check whether an increasing bearing to a fixed object on your starboard side means you are getting closer to or farther from your intended track line. • Before choosing, verify whether your final mental picture shows your vessel ending up north or south of track, and whether you are ahead of or behind the DR position based on your speed and time run.
