Purpose - The 11th edition of U. S. Chart No. 1, Nautical Chart Symbols, Abbreviations and Terms presents the
symbols 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 those
charts, such as Raster Nautical Charts (RNC®). This document also shows the symbols described in the
Regulations of the IHO for International (INT) Charts and Chart Specifications of the IHO published by the
International Hydrographic Organization (IHO), which are portrayed in the three official language versions of
International Chart 1 (INT 1).

Electronic Charts - The symbols and abbreviations displayed on navigation systems portraying NOAA-produced
Electronic Navigational Charts (NOAA ENC®) or NGA-produced Digital Nautical Charts (DNC®) are quite similar to
those used on paper charts for some features, but different for others. This document is not intended as a reference
for 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 the
page 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 1
symbology that are used on charts produced by NOAA or NGA are shown in the NOAA, NGA and the "NGA
reproduction 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 particular
feature. When any of columns 4, 5, or 6 are blank, then the INT 1 symbol has been adopted for use by the
organization for which that column applies. The schematic layout following this introduction shows a typical symbol
table 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 of
NOAA and NGA charts.

Soundings - The sounding datum reference is stated in the chart title. Soundings on NOAA and NGA charts may be
shown in fathoms, feet, fathoms and feet, fathoms and fractions, or meters and decimeters. In all cases the unit of
depth 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 is
shown in the chart title. When the elevations of islets or bare rocks are offset into the adjacent water, they are shown
in parentheses.

Drying Heights - For rocks and banks that cover and uncover, elevations are underlined and are referenced to the
sounding datum as stated in the chart title. When the heights of rocks that cover and uncover are offset into the
adjacent water, they are shown in parentheses.

Shoreline - Shoreline shown on charts represents the line of contact between the land and a selected water
elevation. In areas affected by tidal fluctuation, this line of contact is usually the mean high-water line. In confined
coastal 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 symbolized
by a heavy line (symbol C1). Apparent shoreline is depicted on charts to show the outer edge of marine vegetation
where the shoreline limit would be expected to appear to the observer, or where it prevents the shoreline from being
clearly defined. Apparent shoreline is symbolized by a lighter line (symbols C32, C33, Ca, Cq and Cr).




                                                           4
Landmarks - A structure or a conspicuous feature on a structure may be shown by a landmark symbol with a
descriptive label (see Section E). Prominent buildings that could assist the navigator may be shown by actual shape
as viewed from above (see Sections D and E). On NGA charts, a landmark legend that is shown in capital letters
indicates that the landmark is conspicuous; the landmark may also be labeled "CONSPICUOUS" or "CONSPIC." On
NOAA charts, all landmarks are considered to be conspicuous, and landmark legends shown in all capital letters
indicate the landmark has been positioned accurately; legends using both upper and lower case letters indicate an
approximate 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 in
some foreign waters may be different. IALA buoyage is divided into two regions: Region A and Region B. All
navigable waters of the United States follow IALA Region B rules, except U.S. possessions west of the International
Date 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-port
marks 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 in
both 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 from
seaward, 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. Preferred
channel 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 and
adjacent waterways, where light ranges are given in statute miles. For lights having more than one color, NOAA
charts give only the shortest range of all the colors. On NGA charts, multiple ranges may be shown using the
following convention. For lights with two colors, the first number indicates the range of the first color and the second
number indicates the range of the second color. For example, Fl WG 12/8M indicates that the range of the white light
is 12 nautical miles and the range of green light is 8 nautical miles. For lights with three colors, only the longest and
shortest 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 nautical
miles..

Positioning of Aids to Navigation - The fixed and floating aids to navigation depicted on charts have varying
degrees of reliability. Floating aids are moored to sinkers by varying lengths of chain and may shift due to sea
conditions and other causes. Buoys may also be carried away, capsized or sunk. Lighted buoys may be
extinguished and sound signals may not function, because of ice or other causes. Therefore, prudent mariners will
not rely solely on any single aid to navigation, particularly on floating aids, but will also use bearings from fixed
objects and aids to navigation on shore.

Colors - Color conveys the nature and importance of features found on nautical charts. Chart elements significant to
marine navigation, such as lights, compass roses and regulated areas, are emphasized with magenta. Lateral
marks 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 are
shown as white. Land, and other features that are always dry, are depicted with buff on NOAA charts and gray on
NGA charts. Foreshore and other intertidal features are portrayed with a green tint. Other colors may be used to
provide additional information, such as protected areas, which are outlined in blue or green and mineral lease
blocks, which are outlined in red.

Traffic Separation Schemes - Traffic separation schemes show recommended vessel traffic lanes to increase
safety of navigation, particularly in areas of high-density shipping. These schemes are described in the International
Maritime Organization (IMO) publication Ships' Routeing. Traffic separation schemes are generally shown on
nautical charts at scales of 1:600,000 and larger. When possible, traffic separation schemes are plotted to scale and
shown 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 of
the latest NGA-issued U.S. Notice to Mariners applied to the chart is shown after the edition date. NOAA charts
include the date of the latest U.S. Coast Guard Local Notice to Mariners applied to the chart.

        Lateral marks are generally for well-defined channels. There are two international Buoyage Regions ­ A and B ­ where Lateral marks differ.




130.1




        Note: A preferred channel buoy may also be a pillar or a spar. All preferred channel marks have horizontal bands of color.

        Direction of Buoyage: The direction of buoyage is that taken when approaching a harbor from seaward. Along coasts, the direction is
                                 determined by buoyage authorities, normally clockwise around land masses.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
