🔍 Key Concepts

• Pilotage waters involve close proximity to hazards and require more frequent position checks. • A running fix advances a line of position (LOP) using dead reckoning (DR), which becomes less reliable over longer time intervals. • Recommended practice limits how long you should trust an advanced terrestrial LOP before getting a new observation.

💭 Think About

• In confined pilotage waters, how often should you reasonably be checking or updating your position to maintain a safe navigation margin? • As time increases between fixes, what happens to the accuracy of your dead reckoning, and how does that affect the reliability of an advanced LOP? • Looking at the options, which time interval best matches standard prudent practice for frequent position verification in close quarters?

✅ Before You Answer

• Compare each choice to how rapidly conditions can change and DR error can grow in pilotage waters. • Ask yourself which interval aligns with common guidance that fixes in restricted waters should be obtained at short, regular intervals, not just occasionally. • Eliminate any options that would obviously allow too much time for unnoticed DR error to build up before the next check.
