ALRS Vol. 5 (HF DSC Stations for Sea Areas A3/ A4) shows
HF DSC stations in South Africa (Cape Town Radio) and Australia
(Perth Radio), but none in Reunion or Mauritius. Distress Relays
from-shore should be expected on Safety NET for all 4 SRRs, butany requirement to exchange Distress, Urgency or Safety
communications with the rescue authorities at Reunion and/or
Mauritius will have to use HF SSB Radio through adjacent areas
South Africa (Cape Town Radio, for Reunion) or Australia (Perth, for
Mauritius) - or use Inmarsat-C/Inmarsat-B through the French LES
(for Reunion) and/or the Australian LES.(iv) Ship Reporting Systems
At the time of going to print, ALRS Vol. 1 (Ship Reporting
Systems) identifies a reporting system in place in South African waters,
on a trial basis, for South African vessels only. There are no reporting
systems identified for Mauritius nor for Reunion (and the French
'S URNAV' reporting system only applies to vessels within 50nm of
the coast of France). If our route takes us north oflatitude 30° South,
the Madagascar/Indian reporting systems apply. The Australian
AUSREP system will apply on crossing 75° East - reports into
AUSREP will be forwarded, on request, to the AMVER system
(removing the need for two reports).(v) Pilot Services; Vessel Traffic Systems; Port Operations
ALRS Vol. 6 shows that Durban pilots listen on Ch16; and
work on Ch09, 11, 13 and 14. Durban Port Control listens on Ch16;
with Ch 12 as a working frequency. ALRS Vol. 6 also shows that
