🔍 Key Concepts

• Review how charted notes and symbols describe dangers, restrictions, or historical sites • Consider what types of areas are typically marked as prohibited or restricted on nautical charts • Think about where you would normally see warnings about strong or treacherous currents on a chart or in a Coast Pilot

💭 Think About

• Ask yourself: if a spot is called "The Ruins" and given a precise LAT/LONG, what kind of hazard or feature is the chart likely warning mariners about? • Which of these answer choices would be most important for safe navigation rather than historical interest? • For each option, imagine what chart symbol or note you would expect to see if that condition actually applied there.

✅ Before You Answer

• Check which of the options would most directly affect a vessel’s route planning and safety at that position • Consider whether prohibited or restricted areas are usually tied to a specific point like this, or to a larger outlined zone • Verify which answer choice best matches the kind of information normally given next to a named underwater or partially submerged feature
