🔍 Key Concepts

• Gyro to true and the effect of gyro error East on the indicated course • How leeway from a southwest wind changes your course made good (which side of the ship is the wind on?) • The full compass–deviation–variation–true (CDVT) conversion sequence

💭 Think About

• First, decide which way a southwest wind will push a vessel that is heading generally southeast, and whether that makes the true course made good higher or lower than the steered course. • Work step-by-step from gyro course to true: adjust for gyro error, then think about how you would normally move between compass, magnetic, and true—what signs (E or W) make the number go up or down? • Compare your final true course number with the choices and ask: does this reflect both the correction from gyro error and the sideways push from the wind (leeway)?

✅ Before You Answer

• Be very clear whether gyro error East means the gyro reads higher or lower than the true direction, and therefore whether you must add or subtract it. • Confirm the direction of leeway: is the ship being pushed to port or starboard, and does that increase or decrease the true course angle? • Make sure you apply corrections in a consistent order (don’t mix up when to include leeway versus when to apply variation and deviation).
