A compilation of nautical chart symbols used on electronic navigational charts (ENC), edited to meet international standards and annotated to clarify nuances in the symbol usage as needed. An appendix includes a complete list of all ENC chart objects and attributes.
At the end of 2024, all traditional NOAA paper charts will have been permanently discontinued and the ENC that replaces them will be the only official nautical charts of US waters. These chart symbols will become increasing more important as mariners transition to the use of ENC. Below is a sample page from the important symbols of Section K. Even acclaimed presentations of this section can be incomplete or wrong. References in the right column (INT/NCC) indicate the equivalent paper chart symbol according to the IHO S-4 INT standard, which we include because NOAA uses those symbols on the new NOAA Custom Charts (NCC), which are intended to serve as non-official paper back ups to the official ENC. The NCC are based on the content and style of the ENC, but they replace the official ENC symbols with these historic paper chart symbols. This will likely change once it is more broadly recognized that the ENC are the only official nautical charts. 
Many nav apps do not use the abbreviations (called acronyms by the IHO) for the objects and attributes, but some do, including NOAA's own online ENC viewer, so in these cases having a list of the these terms is helpful.
