Question 451Navigation General

The correct answer is D) Information on the sounding datum. The chart title typically includes information on the sounding datum, which is the reference level used for depth measurements on the chart. This is important for navigational purposes, as it allows mariners to understand the relationship between the charted depths and the actual water depths they may encounter. The other options, such as the date of the first edition or revision, and information on the IALA buoyage system, are not found in the chart title.
