NAVTEX Manual, 2017 Edition (KE951E)
This manual is intended, primarily, for use by maritime Administrations and others concerned with the preparation and broadcasting of maritime safety information. It will also be of interest to seafarers, shipowners and others who need to receive such information in order to safely go about their business at sea.
NAVTEX is an international automated direct-printing service for promulgation of navigational and meteorological warnings and other urgent information to ships. It is one of the two principle methods used for broadcasting maritime safety information in accordance with the provisions of the International Convention for the Safety of Life at Sea, 1974, as amended. It has been developed to provide a low-cost, simple and automated means of receiving maritime safety information and Search and Rescue alerts on board ships at sea and in coastal waters. The information transmitted may be relevant to all sizes and types of vessel and the selective message-rejection feature ensures that every mariner can receive safety information broadcasts which are relevant to their voyage.
SOLAS regulation IV/12.2 states that “Every ship, while at sea, shall maintain a radio watch for broadcasts of maritime safety information on the appropriate frequency or frequencies on which such information is broadcast for the area in which the ship is navigating”.
At the request of the IMO Sub-Committee on Radiocommunications (COM), the NAVTEX Manual was first produced in 1988. Three subsequent editions have been produced, with the fourth edition published in 2005 containing amendments endorsed by the Maritime Safety Committee (MSC) at its seventy-eighth session in
May 2004 by MSC/Circ.1122.
At its seventh meeting in September 2005, the IHO Commission on the Promulgation of Radio Navigational Warnings (CPRNW)* established a working group to review all World-Wide Navigational Warning Service (WWNWS) documentation. The working group included representation from the WMO and firstly prepared
revisions to Promulgation of Maritime Safety Information (resolutions A.705(17)) and A.706(17), World-Wide Navigational Warning Service. The proposed revisions of these resolutions were circulated to IHO Member States under IHB CL 104/2007, endorsed by the Sub-Committee on Radiocommunications and Search and
Rescue (COMSAR) at its twelfth session in April 2008 and subsequently approved by the MSC at its eightyfifth session in November/December 2008 by means of MSC.1/Circ.1287 and MSC.1/Circ.1288, respectively.
The IHO CPRNW Working Group then prepared the revised Joint IMO/IHO/WMO Manual on Maritime Safety Information incorporating the revised information from resolutions A.705(17), as amended, and A.706(17), as amended. The revised text was circulated to IHO Member States under cover of IHB CL 70/2008, endorsed by the COMSAR Sub-Committee at its thirteenth session in January 2009 and subsequently approved by the MSC at its eighty-sixth session in May/June 2009 by means of MSC.1/Circ.1310. The working group subsequently prepared the third revision of the International SafetyNET Manual. The revised text of the International
SafetyNET Manual was circulated to IHO Member States under cover of IHB CL 68/2009, endorsed by the COMSAR Sub-Committee at its fourteenth session in March 2010 and approved by the MSC at its eightyseventh session in May 2010 by MSC.1/Circ.1364.
Continuing with the holistic approach of reviewing all maritime safety information documents from the top-down, the working group prepared the fifth revision of the NAVTEX Manual. The revised text of the NAVTEX Manual was circulated to IHO Member States under cover of IHB CL 74/2010, endorsed by the COMSAR Sub Committee at its fifteenth session in March 2011 and subsequently approved by the MSC at its eighty-ninth session in May 2011 by MSC.1/Circ.1403.
Following the review of all WWNWS documentation, an editorial review has been conducted. As part of this editorial review, MSC.1/Circ.1287/Rev.1 and MSC.1/Circ.1288/Rev.1 were approved by the MSC at its ninety second session in June 2013, and MSC.1/Circ.1310/Rev.1 was approved by the MSC at its ninety-fourth session in November 2014. Following the approval of these circulars, the IHO WWNWS Sub-Committee Working Group reviewed the text of the NAVTEX Manual. This sixth revision of the NAVTEX Manual was endorsed by the IHO and the WMO through the WWNWS Sub-Committee, endorsed by the Sub-Committee on Navigation, Communications and Search and Rescue (NCSR) at its third session in February/March 2016 and subsequently approved by the MSC at its ninety-seventh session in November 2016 by means of MSC.1/Circ.1403/Rev.1, with an entry into force date of 1 January 2018.

Shipping is a truly international industry, and it can only operate effectively if the regulations and standards are themselves agreed, adopted and implemented on an international basis. IMO is the forum at which this process takes place.
