You are navigating in pilotage waters using running fixes. The maximum time between fixes should be about __________.

🔍 Key Concepts

• Pilotage waters mean confined or near-coastal areas where you must closely monitor position due to hazards and traffic • Running fix relies on using one line of position (LOP) at different times, so accuracy degrades as time between LOPs increases • In restricted waters, standard practice is to fix your position frequently enough that you can detect small errors before they become dangerous

💭 Think About

• Ask yourself: in tight, hazard‑filled waters, how often do you realistically need to confirm your position to stay safely within the channel? • Consider which choices are clearly too long for safe navigation near shoals and traffic, and which might be more appropriate offshore instead of in pilotage waters • Think about how far your vessel would travel at a typical speed during each of the time options, and whether that distance is safe to "drift" without an accurate fix

✅ Before You Answer

• Eliminate any option where your vessel would travel so far that you could easily leave the safe water area between fixes • Focus on the two shortest time intervals and ask which one reflects a practical, continuously‑monitored pilotage routine • Remember that in pilotage waters, position checks should be frequent and systematic, not occasional or only once an hour
