Q

While proceeding up a narrow waterway you observe a vessel berthed in the river with slack mooring lines. Which is the most prudent action to take FIRST?

🔍 Key Concepts

• Narrow channels and rivers – responsibilities of vessels under way vs. moored vessels • Effects of speed and vessel wake on moored vessels with slack lines • Order of priority: taking immediate action on your own vessel vs. trying to contact others or external authorities

💭 Think About

• What part of this situation can you control immediately to reduce the risk of the berthed vessel breaking out or being damaged? • In a narrow waterway, which action will most directly reduce the force of your vessel’s wake or suction on a moored vessel? • When is it appropriate to contact authorities or sound danger signals, and when is it more appropriate to quietly adjust your own navigation first?

✅ Before You Answer

• Identify which option changes your vessel’s behavior right away with no delay • Consider which actions are secondary (communication, warnings, reporting) and which are primary (preventing the hazard in the first place) • Verify which choice best reflects good seamanship and prudence in a narrow channel when passing close to a vessel with slack moorings
