LESSON 3: NAUTICAL PUBLICATIONS

 AGENDA: –Navigator’s Reference Library –Chart/Publication Correction System –Plotting Equipment  Applicable reading: Hobbs, pp , Lesson 3: Nautical Publications

Coast Pilots  Provide supplemental information about navigation in U.S. coastal waters.  Information includes: –topographical features –navigation aids –normal local weather conditions –recommended tracks –pilot information –descriptions of ports and harbors

Sailing Directions  Provide supplemental information about navigation in foreign coastal waters.  Information provided is similar to that found in Coast Pilots.  Divided into different volumes –8 volumes are Planning Guides for ocean basin transits –35 are Enroute Directions for piloting in coastal waters.

Fleet Guides  Provide information for use by U.S. Navy ships, including:  Fleet Guides exist for ports frequently visited by the U.S. Navy in both the U.S. and foreign countries. –Command information (e.g. SOPA) –Navigation information (e.g. prevailing tides/currents) –Logistics (e.g. fuel/water) –Port operations (e.g. Comms facilities etc.) –Repair facilities

Light List  Lists aids to navigation in U.S. waters, including: –lighted aids to navigation –unlighted buoys –daybeacons –fog signals –radiobeacons –Loran-C coverage

List of Lights  Describes aids to navigation found in foreign waters and selected U.S. coastal regions.  Similar to Light List but does not contain information on unlighted navigation aids.

Distances Between Ports (Pub 151)  Lists great circle distances among the most frequently traveled sea routes throughout the world.

Hazard and Depth Symbology  Symbols are also used to denote specific hazards to navigation, such as partially submerged wrecks, etc..  Chart Number 1 is the reference for all chart symbology.

Pilot Charts  Name is misleading- they really cover major ocean basins and not piloting (coastal) waters.  Provide meteorological, hydrographic, and navigational information for a particular ocean area.  Extremely valuable in voyage planning.

NIMA Catalogue of Maps, Charts, and Related Products  Illustrated catalog of maps, charts, publications, and other related products produced by NIMA.  Contains serialized drawings of the world which allow the navigator to locate charts and Sailing Directions that cover areas of interest.  Published as an eleven volume set.

Step #1 Identify the Coastal Region/Subregion Example: The navigator is planning to visit Rio de Janeiro, Brazil.

Step #2 Locate the Small-scale Coastal Chart

Step #3 Locate the Large-scale Approach Charts

NOS Nautical Chart Catalogue  Set of drawings, very similar to those found in the DMA catalog.  Cover U.S. waters

Chart and Publication Correction System  Corrections to charts and publications are disseminated via Notice to Mariners and Local Notice to Mariners. –Notice to Mariners - issued by NIMA and contain changes relating to oceanic and coastal areas worldwide.  Navigators are not required to immediately enter changes on every chart/publication.

REVIEW  What book would I look in to find:  Information on a port such as Repair facilities and command information?  A lighted navaid in US waters?  A lighted navaid in foreign waters?  Chart corrections?  Chart symbology?  The distance traveled from Norfolk to Ingleside Texas?  What 3 pieces of information can you find on a nautical slide rule?
