These are specialist charts providing additional information which can be used alongside the standard nautical charts.
Load Line Regulations
Merchant Shipping (Load Line) Regulations cover the draught to which vessels subject to SOLAS regulations may be loaded in designated zones across the world. The Load Line Chart (D6083) reflects changes made in the 1998 Merchant Shipping Regulations and includes the latest designated zones and seasonal periods relating to load line rules.
Maritime Security Charts
Maritime Security Charts contain security related information for mariners relating to the geographical area of the chart. They also include details of reporting schemes and regional contacts, as well as general security advice. The security charts should be used in conjunction with standard nautical charts and publications. For more information, see the Security Related Information to Mariners page, which includes downloads for all the charts.
The World Time Zone Chart
This chart was originally devised so that mariners, in any part of the world, could relate their local time to standard Greenwich Mean Time. The course of the International Date Line is depicted within the latest edition.
These charts are essential for use in passage planning for ocean voyages. They include routes and distances between major ports, ocean currents, ice limits, load lines and wind roses, with expected meteorological and oceanographic conditions for each month of the year. Five charts cover the oceans of the world; North Atlantic, South Atlantic, North Pacific, South Pacific and the Indian Ocean.
Mariners' Routeing Guides
Routeing Guides provide important passage planning information in addition to details of traffic separation schemes for the major shipping areas of the English Channel, North Sea, Gulf of Suez, Malacca and Singapore Straits.
Port Approach Guides
These charts each cover a single port, and contain all the information a mariner might need when planning a port approach. They also improve situational awareness, providing mariners with a tool that compliments the equivalent-coverage Standard or Electronic Nautical Charts.
Planning Charts are designed to assist the planning process and can also be used for educational, travel and decorative purposes. They are a series of small scale charts covering significant ports throughout the world, that are available in various scales.
Co-tidal and Co-range Charts are used primarily to predict offshore tidal conditions.
Astronomical Charts facilitate the accurate plotting of a ship's position from astronomical observations.
These Charts are used in passage planning to plot great circle routes as a straight line. They are useful for devising composite rhumb line courses. Fifteen charts cover the world at scales of 1:13,500,000 and 1:26,500,000.
Magnetic Variation Charts
These charts show the variation of magnetic fields. While local information is shown on all charts, this series provides more detailed coverage on a worldwide level.
Meteorological Charts and Diagrams
These charts form a series of 27 meteorological working charts.
