Chart Symbols

Studying a harbor layout does very little good without understanding the symbols and what they signify. It pays to learn the symbols found on nautical charts.

These are widely available in an array of nautical books and on the reverse side of many charts. The most readily available and always up-to-date source is found in your maritime government; in the USA it is NOAA—Office of Coast Survey. This PDF downloadable book contains globally used symbols. The book is called

Chart No. 1: Symbols, Abbreviations, and Terms.

Download the Chart 1 on the Internet for free by going to: 

Or get a spiral-bound hard copy on Amazon for $12 or so.

Chart 1

It is imperative that you not gloss over this section as you read, so we advise that you really gain access to Chart 1 now. Below we will take you through some of the more common symbols and give you a brief view into Chart 1.

Now look up the symbols on the following pages of Chart 1:

  • C 13. Learn the heights of land.
  • Not sure why Bridges are in Section D under Cultural Features—but they are. Check those out.
  • F 14. Jetties and Piers.
  • Peruse Sections H, I, and J to learn currents, depths, and bottom types.
  • Pay particular attention to Section K—Rocks, Wrecks, and Obstructions.
  • View L 30.1 to see the submarine cable shown in the animation above.
  • View M 10 through 18, then figure out the two examples of routing measures shown for paper and electronic charts.
  • Study N 2 and N 12.
  • Get a feel for Section P—Lights and Section Q—Buoys and Beacons. We’ll go through these later. Study Q 130 in particular.
  • Peruse R, S, and T.
  • See that there is a list of abbreviations and an index at the end.
  • Finish by viewing the Appendix.
