About this guide: The navigation equipment requirements in this guide come from Chapter V of the International Convention for the Safety of Life at Sea (SOLAS), and include the SOLAS requirements up to and including the amendments adopted in 2009, which came into force 1 July 2010.
The list refers to various versions of SOLAS, such as "SOLAS 1981" and "SOLAS 2000". Since not all navigation equipment requirements are retroactive when they are adopted, requirements for older ships are derived from both new and older SOLAS versions.
"SOLAS 1981" refers to the major revision of SOLAS Chapter V adopted in 1981 and which came into force 1 September 1984. This guide does not attempt to accurately list equipment required on ships built before 1 September 1984. However, a ship built before 1 September 1984, but equipped with the systems required on a ship built on that date, will meet or exceed all navigation equipment requirements that apply to it. Requirements identified as "SOLAS 1981" include some revisions that were adopted between 1981 and 2000.
"SOLAS 2000" refers to the major revision of SOLAS Chapter V adopted in 2000, and which came into force 1 July 2002. It also includes the December 2002 amendments on Automatic Identification Systems (AIS) which came into force on 1 July 2003. Other SOLAS references such as "SOLAS 2004" refer to amendments adopted in that year.
