== Scope == 
The International Convention on the Safety of Life at Sea (SOLAS) includes a requirement for all ships to carry to up-to-date nautical charts and publications for the intended voyage. Progressively from 2012, the chart carriage requirement for certain classes of vessels is to be satisfied by electronic means using an Electronic Chart Display and Information System (ECDIS).

Feedback from those involved in the use of charts and electronic charting systems including manufacturers, distributors, users, ship owners, regulatory authorities, pilots, harbour authorities and others indicates a requirement to provide guidance on the regulations and the status of equipment that is available in the market today. In particular the differences between the various types of equipment and the differences between the various types of chart data offered to the users are unclear with respect to the regulations in place.

This document has been produced to help clarify some of the uncertainties. It is not intended to replace or amend national or international rules and regulations. Readers should always refer to the relevant national administration or Flag State for the latest detailed information.

This document consists of a number of interrelated sections. This first section contains information on various aspects of electronic charts and electronic chart display systems in the form of questions and answers. The main emphasis is on what can be used to satisfy the SOLAS carriage requirements for charts.

:* Section 1: Overview of electronic charting and regulations
:* Section 2: A list of points of contact for detailed information on Flag State Implementation of ECDIS
:* Section 3: ECDIS Training
:* Section 4: Technical aspects of electronic charts
:* Section 5: Appendix: References, glossary, further reading

== Implementation benefits ===
S-66 is very beneficial to any person working with ENC or ECDIS. It provides a detailed introduction and general information on the field, and also useful information such as links to online resources, and a list of abbreviations.

== Implementation guidelines ==
S-66 is for information purposes and cannot be implemented. It provides detailed information on ENC, ECGIS, flag authorities, training objectives for ECDIS training, and technical details of electronic charts.
