NOAA Specialty Charts NOAA provides several types of specialty charts for professional and recreational mariners: Small Craft Chart Folios and Books--Specially designed for small, non-commercial users, these charts are arranged in spiral-bound booklets or fold-out folio collections. Oil and Gas Leasing Areas--"Block Charts" document the location of oil and gas drilling locations in the Gulf of Mexico--essential for safe passage. Training Charts--special versions of selected NOAA charts that are standardized for use in Coast Guard Examinations.  Get yours to practice navigation problems before the test!  Chart 1210TR is a favorite of Coast Guard Auxiliaries, Power Squadrons, and Sailing Schools for plotting practice as it also includes an abridged version of Chart No. 1 on the chart back.  Marine Weather Service Charts--a series of 16 charts covering the waters of the U. S., Puerto Rico, Guam, and the Northern Marianas to list NWS radio stations, telephone numbers, and web addresses. Chart No. 1--It's not really a chart but a publication that lists and defines all of the symbols use on U. S.-manufactured charts.
