Question 1 of 2707066636ee928f7522a1c51a65b

Your vessel is steering course 027° per standard magnetic compass (psc), variation for the area is 19°W, and deviation is 2°E. The wind is from the north-northwest, producing a 5° leeway. What true course are you making good?

Question 1 of 27070

🔍 Key Concepts

• Compass to true conversions using variation and deviation • Effect and sign of leeway on course made good • Remembering the standard order: Compass ↔ Magnetic ↔ True

💭 Think About

• Start from the given psc (standard magnetic compass) course and step-by-step convert it toward true. Are you adding or subtracting each correction based on its direction (E or W)? • Think about a north-northwest wind on a vessel heading roughly northeast. Will the wind push your bow toward the wind or away from it? That determines the sign of leeway. • Once you find the true heading from compass, decide how leeway alters the course made good. Does leeway make your actual track more northerly, southerly, easterly, or westerly?

✅ Before You Answer

• Be clear on the sign rule: West is Best, East is Least (or your preferred memory aid) when going between magnetic and true, and how deviation applies to compass vs magnetic. • Confirm whether you apply deviation between compass and magnetic, and variation between magnetic and true – not the other way around. • Double-check if the final answer you pick is a true course made good (after leeway), not just the true heading without wind effects.
