  • 5. INTRODUCTIONPurpose - The 11th edition of U. S. Chart No. 1, Nautical Chart Symbols, Abbreviations and Terms presents thesymbols depicted on paper nautical charts produced by the National Oceanic and Atmospheric Administration(NOAA) and the National Geospatial-Intelligence Agency (NGA), as well as digital raster representations of thosecharts, such as Raster Nautical Charts (RNC®). This document also shows the symbols described in theRegulations of the IHO for International (INT) Charts and Chart Specifications of the IHO published by theInternational Hydrographic Organization (IHO), which are portrayed in the three official language versions ofInternational Chart 1 (INT 1).Electronic Charts - The symbols and abbreviations displayed on navigation systems portraying NOAA-producedElectronic Navigational Charts (NOAA ENC®) or NGA-produced Digital Nautical Charts (DNC®) are quite similar tothose used on paper charts for some features, but different for others. This document is not intended as a referencefor the use of these vector-based products.Change in Column Order - Previous editions of U.S. Chart No. 1 showed U.S. symbology on the left side of thepage and INT 1 symbology in the second column from the right. This edition of Chart No. 1 has reversed the order.INT 1 symbols now appear in the second column from the left, after the symbol number. Any variations from INT 1symbology that are used on charts produced by NOAA or NGA are shown in the NOAA, NGA and the “NGAreproduction of foreign charts” columns (columns 4, 5, and 6 respectively). When columns 4 and 5 are combined, this indicates that NOAA and NGA use the same symbol for that particularfeature. When any of columns 4, 5, or 6 are blank, then the INT 1 symbol has been adopted for use by theorganization for which that column applies. The schematic layout following this introduction shows a typical symboltable page and describes the table headers and the types of information presented in each of the columns.Sample Chart Layouts – Section A presents two schematics showing typical layouts of the major elements ofNOAA and NGA charts.Soundings - The sounding datum reference is stated in the chart title. Soundings on NOAA and NGA charts may beshown in fathoms, feet, fathoms and feet, fathoms and fractions, or meters and decimeters. In all cases the unit ofdepth used is shown in the chart title and outside the border of the chart in bold type. (See item Ab in Section A.)Heights - Heights of lights, landmarks, structures, etc. refer to the shoreline plane of reference. The unit of height isshown in the chart title. When the elevations of islets or bare rocks are offset into the adjacent water, they are shownin parentheses.Drying Heights - For rocks and banks that cover and uncover, elevations are underlined and are referenced to thesounding datum as stated in the chart title. When the heights of rocks that cover and uncover are offset into theadjacent water, they are shown in parentheses.Shoreline - Shoreline shown on charts represents the line of contact between the land and a selected waterelevation. In areas affected by tidal fluctuation, this line of contact is usually the mean high-water line. In confinedcoastal waters of diminished tidal influence, a mean water level may be used. The shoreline of interior waters(rivers, lakes) is usually a line representing a specified elevation above a selected datum. Shoreline is symbolizedby a heavy line (symbol C1). Apparent shoreline is depicted on charts to show the outer edge of marine vegetationwhere the shoreline limit would be expected to appear to the observer, or where it prevents the shoreline from beingclearly defined. Apparent shoreline is symbolized by a lighter line (symbols C32, C33, Ca, Cq and Cr). 4
  • 6. Landmarks - A structure or a conspicuous feature on a structure may be shown by a landmark symbol with adescriptive label (see Section E). Prominent buildings that could assist the navigator may be shown by actual shapeas viewed from above (see Sections D and E). On NGA charts, a landmark legend that is shown in capital lettersindicates that the landmark is conspicuous; the landmark may also be labeled “CONSPICUOUS” or “CONSPIC.” OnNOAA charts, all landmarks are considered to be conspicuous, and landmark legends shown in all capital lettersindicate the landmark has been positioned accurately; legends using both upper and lower case letters indicate anapproximate position.IALA Buoyage System - The International Association of Marine Aids to Navigation and Lighthouse Authorities(IALA) Maritime Buoyage System is followed by most of the world’s maritime nations; however systems used insome foreign waters may be different. IALA buoyage is divided into two regions: Region A and Region B. Allnavigable waters of the United States follow IALA Region B rules, except U.S. possessions west of the InternationalDate Line and south of 10° north latitude, which follow IALA Region A. The major difference in the two buoyage Regions is the color of the lateral marks. Region A uses red-to-portmarks and Region B uses red-to-starboard marks when entering from seaward. The shapes of lateral marks,however, are the same in both Regions: can to port and cone (nun) to starboard, when entering from seaward.Cardinal and other marks, such as isolated danger marks, safe water marks, and special marks are also the same inboth Regions. Section Q and Appendix 1 illustrate the IALA Buoyage System for both Regions A and B.U.S. Lateral Marks - Most of U.S. waters lie withing IALA Region B. In the U.S. system, on entering a channel fromseaward, buoys and beacon dayboards on the starboard side are red with even numbers and have red lights, if lit.Buoys and beacon dayboards on the port side are green with odd numbers and have green lights, if lit. Preferredchannel buoys have red and green horizontal bands with the top band color indicating the preferred side of passage.Light Range (Visibility) - A light’s range or visibility is given in nautical miles, except on the Great Lakes andadjacent waterways, where light ranges are given in statute miles. For lights having more than one color, NOAAcharts give only the shortest range of all the colors. On NGA charts, multiple ranges may be shown using thefollowing convention. For lights with two colors, the first number indicates the range of the first color and the secondnumber indicates the range of the second color. For example, Fl WG 12/8M indicates that the range of the white lightis 12 nautical miles and the range of green light is 8 nautical miles. For lights with three colors, only the longest andshortest ranges are given. For example, Fl WRG 12-8M indicates that the range of the white light is 12 nautical miles,the range of green light is 8 nautical miles, and the range of the red light is somewhere between 8 and 12 nauticalmiles..Positioning of Aids to Navigation - The fixed and floating aids to navigation depicted on charts have varyingdegrees of reliability. Floating aids are moored to sinkers by varying lengths of chain and may shift due to seaconditions and other causes. Buoys may also be carried away, capsized or sunk. Lighted buoys may beextinguished and sound signals may not function, because of ice or other causes. Therefore, prudent mariners willnot rely solely on any single aid to navigation, particularly on floating aids, but will also use bearings from fixedobjects and aids to navigation on shore. 5
  • 7. Colors - Color conveys the nature and importance of features found on nautical charts. Chart elements significant tomarine navigation, such as lights, compass roses and regulated areas, are emphasized with magenta. Lateralmarks on NOAA charts are shown with a red or green fill. Shades of blue depict potential hazards to navigation,typically shallow water and submerged obstructions. Areas of deeper water believed to be clear of obstructions areshown as white. Land, and other features that are always dry, are depicted with buff on NOAA charts and gray onNGA charts. Foreshore and other intertidal features are portrayed with a green tint. Other colors may be used toprovide additional information, such as protected areas, which are outlined in blue or green and mineral leaseblocks, which are outlined in red.Traffic Separation Schemes - Traffic separation schemes show recommended vessel traffic lanes to increasesafety of navigation, particularly in areas of high-density shipping. These schemes are described in the InternationalMaritime Organization (IMO) publication Ships’ Routeing. Traffic separation schemes are generally shown onnautical charts at scales of 1:600,000 and larger. When possible, traffic separation schemes are plotted to scale andshown as depicted in Section M.Conversion Scales - Depth conversion scales are provided on all charts to enable the user to work in meters,fathoms or feet.Correction Date - The date of each new chart edition is shown below the lower left border of the chart. The date ofthe latest NGA-issued U.S. Notice to Mariners applied to the chart is shown after the edition date. NOAA chartsinclude the date of the latest U.S. Coast Guard Local Notice to Mariners applied to the chart.Additional Resources - Information about the use of nautical charts, aids to navigation, sounding datum, and thegeneral practice of navigation can be found in The American Practical Navigator, available via the “Publications”hyperlink at http://msi.nga.mil/NGAPortal/MSI.portal. Tide and tidal current data in U.S. waters is available from the NOAA Center for Operational OceanographicProducts and Services at http://tidesandcurrents.noaa.gov.
