All symbols and abbreviations found on a nautical chart are defined in what chart resource?

• A. Legend
• B. Chart 1
• C. Glossary
• D. Plotting Manual

Answer: (B)

The main idea here is knowing where official definitions for all chart symbols and abbreviations are kept. Chart 1 is the standard reference that lists every symbol and abbreviation used on nautical charts and explains how to interpret them, providing a consistent key across different charts and regions. A chart’s own legend shows the symbols that appear on that specific chart, but it doesn’t cover the entire set used elsewhere. A glossary covers terms, not the pictorial signs and shorthand used on charts. A plotting manual focuses on how to plot courses and positions, not what the symbols mean. So Chart 1 is the best resource for understanding all chart symbols and abbreviations.
