Channel 13: Navigation - used by any vessel for safety communica-

tions regarding the maneuvering of vessels or directing of a vessels

movements. Ship-to-ship and secondarily ship-to-coast communica-

tions. Commonly called the Bridge-to-Bridge channel. For routine

operations, radio power must be reduced to one watt.

broadcast information concerning environmental conditions in which

hazards to navigation. One-way broadcast from coast-to-ship stations.

Channel 16: Emergency - Used if your vessel is sinking or on fire,

someone has been lost overboard, or there is grave and imminent

danger to life or property. Every ship is obliged to give priority to

radio distress communications. Calling - This channel is also used to

establish communication with another marine radio station. After

contact is made, switch to a working channel. Due to congestion on

channel 16, particularly in high traffic areas, the FCC has approved

channel 9 as a second hailing channel.

Channel 17: State Control - Used by state and local government

vessels to coordinate, regulate and control boating activities and the

rendering of assistance.

Channel 22: U.S. Coast Guard - For use by any vessel for exchange

Establish contact on channel 16 then shift to channel 22 as directed

by the U.S. Coast Guard.
