Question 1 of 2066636ee928f7522a1c51a664

Your vessel is steering a course of 337°psc. Variation for the area is 13°W, and deviation is 4°E. The wind is from the south, producing a 3° leeway. Which true course are you making good?

🔍 Key Concepts

• True, Magnetic, Compass (T-M-D-C) relationship and how to apply variation and deviation • How leeway (from the wind) changes the course actually made good over the ground • The sign convention for West and East corrections when converting between compass, magnetic, and true

💭 Think About

• Start from the given per ship’s compass (psc) course and carefully apply deviation and variation step-by-step to reach a true course before you think about leeway • Ask yourself: does West variation make true course greater or smaller than magnetic? Does East deviation make compass greater or smaller than magnetic? • After you have a true course through the water, think about a southerly wind: will it push your vessel’s head toward the east or toward the west, and does that make the course made good numerically larger or smaller?

✅ Before You Answer

• Write out the full T–M–C table (or C–M–T, depending on your habit) and label each line clearly • Check the signs: are you adding or subtracting 13°W variation and 4°E deviation in the correct direction? • After applying leeway, verify whether your final true course made good is to the east or west of your original true course through the water before looking at the multiple-choice options
