In order to mark dangerous coastlines, hazardous shoals, reefs, safe entries to harbors theChilean authorities maintain 650lighthouses from the boundary toPeru until theAtlantic Ocean. Information on these lighthouses is presented in the following separate lists that follow the shoreline from North to South as provided by the United States'National Geospatial-Intelligence Agency (NGA). The NGA lists also 26 Argentine lighthouses in the Beagle Channel zone as part of the Chilean list of lights. This NGA list does, however, not include the lighthouses in thelakes of Chile nor any Chilean lighthouses inAntarctica (seeList of Antarctic and subantarctic islands).
Information is tabulated in seven columns as follows:
Numbers assigned to each light, RACON or RAMARK by NGA andAdmiralty. RACONs and RAMARKs located at a light are listed with the light. Those not located at a light are assigned separate numbers.
Name and descriptive location of the light or buoy, RACON or RAMARK. This column is intended to describe the location of the navigational aid and to distinguish it from others in proximity. They can indicate the following: lights intended for landfall or having a visibility (range) of 15 miles or more; floating aids; lightships and LANBYs; all other lights not mentioned above.
Latitude and longitude (approx.) of a navigational aid to the nearest tenth of a minute, intended to facilitate chart orientation (use column 2 and the appropriate chart for precise positioning).
Characteristics of light, buoy, RACON or RAMARK characteristic (see Characteristics of Lights chart for explanation of lights).
Height of light infeet and inmeter, andrange, the distance, expressed in nautical miles, that a light can be seen in clear weather or that a RACON or RAMARK can be received.
