🔍 Key Concepts

• Compass deviation vs. variation and how each affects a compass bearing • How to use a range (two charted objects in line) to find the true bearing • Relationship between true, magnetic, and compass bearings (T–V–M–D–C)

💭 Think About

• What is the true bearing of the line formed by South West Ledge Light and New Haven Outer Channel Range Rear Light as shown on the chart? • If your standard magnetic compass reads 338.5° when you are exactly on that range line, is your compass reading higher or lower than the true bearing? What does that say about deviation direction (E or W)? • Once you know the direction (E or W), how many degrees apart are the true range bearing and the compass bearing?

✅ Before You Answer

• Confirm the true range bearing from the chart first; do NOT assume it. • Carefully apply the T–V–M–D–C relationship in the correct order and sign convention. • Double‑check whether a compass that reads more westerly or more easterly than the true line indicates east or west deviation.
