When should a navigator rely on the position...

🔍 Key Concepts

• Floating aids to navigation (buoys) can move from their charted positions due to wind, current, and sea state • Coast Guard guidance on how much trust to place in buoys versus fixed aids (lights on structures, beacons, daymarks) • Good seamanship principles: always question whether any single aid can be relied on without cross‑checking

💭 Think About

• Think about whether floating aids are perfectly fixed in place or allowed some movement around their assigned position • Ask yourself in what situations a prudent navigator would treat buoys as absolutely reliable versus using them with caution and cross‑checks • Consider which answer choices incorrectly limit the use of floating aids by time of day, weather, or location

✅ Before You Answer

• Check which options suggest conditional use based only on environment (calm weather, daylight, harbor)** and ask if that matches how buoys are actually used at sea • Verify that floating aids are subject to watch circle / movement and can go off station, so total reliance may not be prudent • Think about the principle: you should always cross‑check position with more than one source, especially when using floating aids

When should a navigator rely on the position of floating aids to navigation?

During calm weather only

Only when fixed aids are not available

During daylight only
