🔍 Key Concepts

• Heights of lights on nautical charts are normally measured from a specific vertical datum • Think about which water level reference is most useful to mariners for knowing how high a light appears above the sea • Recall how charted light heights differ from charted depths (soundings) in terms of reference level

💭 Think About

• Ask yourself: For safe navigation, do we want the light height referenced to the highest, the lowest, or an average water level? Why? • Consider which of these reference levels is commonly used on U.S. charts for the elevation of lighthouses and other aids to navigation • Think about how changing tide height would affect the apparent height of a light above the water if it were measured from different reference levels

✅ Before You Answer

• Identify which option is actually used as the standard chart datum for heights of lights on U.S. nautical charts • Make sure you do NOT confuse the datum for soundings (depths) with the datum for light elevations • Eliminate any choice that would make the charted light height misleading to mariners at most stages of the tide
