Normal Operating Procedure

Most calls to other vessel or stations are

made on channel 88. After listening to ensure

channel 88 is clear, call the other station,

repeating both call signs three times.

e.g.“Coast Guard, Coast Guard,Coast Guard,

This is –

Seaspray, Seaspray, Seaspray,

Over.”

Once contact has been established, move

straight to another channel (e.g. 91 or 94) to

continue your conversation leaving channel 88

clear for emergencies or further calls. Don’t

forget to return to channel 88 or select dual

watch when you have finished otherwise you

may miss other calls meant for you.

Emergency Procedures

All emergency calls should be made on

channel 88. There are three main types of

Emergency call.

1. “MAYDAY, MAYDAY, MAYDAY”

This call should be used where you are in

grave and imminent danger and require

immediate assistance. You should call

MAYDAY three times followed by your vessels

name or callsign three times. Then state your

position, a brief description of your vessel, the

nature of the emergency, the number of

people on board and their condition. If you

hear no reply, repeat the call at short intervals

because someone may be able to hear you

but you might not be able to receive their

reply.

After contact has been made, follow any

instructions given to you.

2. “PAN PAN, PAN PAN, PAN PAN”

Use this call when an emergency situation

exists but there is no immediate danger. The

call should be made the same way as the

MAYDAY call. If you hear no reply repeat the

call at regular intervals.

3. “SECURITE, SECURITE, SECURITE”

(Pronounced Say-cure-e-tay).

This call is used to warn other shipping of

dangers or hazards e.g. bad weather,

container adrift etc. The call may be made to a

local monitoring station or to all ships in the

area.
