🔍 Key Concepts

• Set and drift of current relative to your intended track • Using relative bearings (increasing vs decreasing) to tell if you’re being set toward or away from a danger • How distance off (by radar range or abeam position) tells you if you’re closing a hazard

💭 Think About

• Which option shows you are getting closer to the obstruction rather than just near land or shallow water in general? • For the bearing option: if a fixed aid’s bearing is changing in a certain direction, does that mean you’re moving toward or away from the obstruction? • For the radar range option: does a decreasing range to a point on shore always mean you are being set onto the specific obstruction, or could you still be safely clear?

✅ Before You Answer

• Verify which aid or reference in the choices is geographically closest to the obstruction itself on the chart • Check which observation would give you a clear, unambiguous indication that your track is intersecting the obstruction (not just ‘it’s getting shallower’ or ‘land is closer’) • Confirm whether an abeam position at a specific distance from a known buoy would mean you have already crossed onto the obstruction’s side of your intended track
