Step 1
First you should understand that channel sixteen is used for calling other vessels (then switch to a working channel) and for emergency communications. Do not have conversations on channel sixteen our request a radio check.
Once you have made contact switch to a recreational working channel such as 68, 69, 71, 72, or 78 to have your conversation. -
Step 2
CHANNEL 22A or 22 Alpha is the primary working channel the Coast Guard uses for communication with the boating public and this is where severe weather warnings, hazards to navigation, and other maritime warnings are broadcast by the Coast Guard. A message may be broadcast on channel 16 to switch to 22A for a detailed message.

Step 3
CHANNEL 13 is the navigation and piloting channel. Most Locks and bridges monitor channel 13, and it must be used for navigation and piloting purposes only.
CHANNEL 6 is a ship-to-ship frequency used for safety-related communications.
Don't think of your marine radio as a CB radio. Enforcement of proper use can include hefty fines, especially for false distress calls.
Remember that you may cost someone else their life if they are trying to make a distress call and you are chit chatting on channel 16 and you cause the Coast Guard to not hear their faint distress call. -
Step 4
Marine VHF radios often have a feature called DSC or Digital Select Calling. This feature allows DSC enabled radios to call another DSC enabled radio if you know their identifying number. Once contact is made through a DSC message you can switch to a working channel. This avoids having to make calls on channel 16.
