NOTE  

“Over and Out” 

The most commonly misused procedure words are “over and out” within the 

same transmission. “Over” means you expect a reply. “Out” means you are 

finished and do not expect a reply.

You are required to listen to Channel 16 while standing by. Channel 16 is the 

distress and safety channel used for establishing initial contact with another station 

and for emergency communication. The Coast Guard also monitors Channel 16 for 

safety purposes for everyone on the water.

NOTE  

Channel 9 may be used by recreational vessels for general-purpose calling.  

This frequency should be used whenever possible to help relieve congestion  

on Channel 16. The Coast Guard generally does not make urgent marine 

information broadcasts or weather warnings on Channel 9. Boaters are still 

asked to “keep watch” on Channel 16 whenever the radio is turned on and  

not in use with another station.

n

   Make sure the radio is On.

n

   Make sure you are in standby listening mode on Channel 16. Make sure 

Channel 16 is not in use. 

n

   When the channel is open (quiet), press the Talk button and call a vessel. Hold 

the radio or microphone several inches from your face and speak clearly and 

distinctly in a normal voice tone. Say “name or station being called,” “THIS IS 

[your vessel name or call sign].”

n

   Once contact is made, you must leave Channel 16 and go to another working 

channel. See channel listing in the appendix.

Corsair: “Vagabond, this is Corsair. Over.”

Vagabond: “Please switch and answer on Channel 68 (or any proper working 

channel). Over.”

Corsair: “Switching to Channel 68. Over.”

Boaters may make and receive radiotelephone calls to and from any number on  

the telephone network by using the services of public coast stations. For a fee,  

calls can be made between your radio and telephones on land, sea and in the air.  

See the appendix for the public correspondence (marine operator) channels.
If you plan to use these services, consider registering with the operator of the  

public coast station that you plan to work through. These services can provide  

you with detailed information and procedures to follow.

You may disclose privileged information during a radiotelephone call.  

Keep in mind that your transmission is NOT private, as it is on a regular  

telephone. Both sides of the conversation are being broadcast and can be  

heard by anyone who has a radio and tunes to the channel you are using.
