  • Of receiving shore-to-ship Distress Alerts.
  • Of transmitting and receiving ship-to-ship Distress Alerts.
  • Of transmitting and receiving search and rescue coordinating communications.
  • Of transmitting and receiving on-scene communications.
  • Of transmitting and receiving locating signals.
  • Of receiving maritime safety information.

26
Q

Distress MESSAGE Format

A

Mayday
Identity (name, Call Sign, MMSI)
Position
Danger (nature)
Assistance
Number of Persons
Information (any other information)
Over

Numbers are always said in the format TWO-FOUR, not Twenty Four

27
Q

When may a station transmit a Distress Relay Alert

A

After receiving a distress alert that has not been acknowledged within 5 minutes

When a vessel in distress is unable to make the alert themself

When the controlling station or MRCC decides further assistance is required

28
Q

Distress Alert Relay format (Call and Message)

A

Mayday relay x 3
All Stations/CS x 3
This is
Name x 3 (own vessel)
Call Sign
MMSI

Mayday Relay x1
Name + Callsign +MMSI (vessel in danger)
Position
Danger (nature)
Assistance required
Number of persons
Information (other)
Over

29
Q

How would a CS alert ships to a distress in their area?

Far from their area?

A

DSC Mayday alert relay to:
All ships
Group of ships
Geographical Area
Specific Vessel

Distress alert relay through satellite, EGC through Inmarsat C

30
Q

In Acknowledging VHF/MF DSC distress Area A1-A2 you would:

A

Wait a short period to allow MRCC to do so

31
Q

Acknowledging VHF/MF DCS Distress Area A3-A4
In the vicinity of the distress

A

Acknowledge Immediately by R/T and inform an MRCC

32
Q

You hear an VHF/MF DSC distress in A3-A4
You are not in the vicinity of the distress, and the distress alert repeats

A

acknowledge by DSC to terminate and relay the alert to an MRCC

33
Q

Acknowledging HF DSC?

A

do not do by any means whatsoever, set watch to R/T frequency, if no acknowledgement by MRCC or no subsequent communications, relay the distress alert by any means (HF or Satellite)

34
Q

False DSC alert Procedure

A
  1. Let the alert finish
  2. Stop it from repeating
  3. Cancel alert by R/t giving your MMSI number
  4. Inform an MRCC or CS by any means necessary
