 *Sea area A2—An area within a coverage of at least one coast station continuous  listening on MF (2187.5&nbsp;kHz) other than Area A1
 *Sea Area A3—An area, excluding sea areas A1 and A2, within the coverage of an RMSS (Recognised Mobile Satellite System). For ships fitted with Inmarsat [[geostationary satellite]], this area lies between about latitude 76 Degrees North and South, but excludes A1 and/or A2 designated areas. Inmarsat guarantees their system will work between 70 South and 70 North though it will often work to 76 degrees South or North. For vessel fitted with Iridium A3 also includes the polar regions
-*Sea Area A4—An area outside Sea Areas A1, A2 and A3 is called Sea Area A4. For ships fitted with Inmarst as their RMSS this is essentially the polar regions, north and south of about 76 degrees of [[latitude]], excluding any A1, A2 and A3 areas. For ships that carry Iridium as their RMSS, there is no Area A4.
