If you have questions about the use of your marine radio you can contact the FCC Call Center at 1-888-CALL-FCC. For safety and efficient navigation of vessels, the maritime radio frequency bands are separated into four groups. Specific frequencies within each are assigned for particular safety and functional applications, such as ship to shore communications, US Coast Guard use, and navigation in waterways and ports. You may not have access to some which are not-for-public-use frequencies, and you are required to monitor and use others which are safety and navigational procedure frequencies. GETTIN. STARTE. Maritime Radio Services Operation The four groups you will have occasion to use are the U.S.A. Regular Band of 52 channels, the Canadian Band of 56 channels, the International Band of 55 channels, and the Weather Band of 10 channels. Some of these are receive (listen) only, such as the weather channels. The emergency channel 16 is restricted to hailing of other vessels, distress calls and safety purposes only. Known as the Hail and Distress Channel, it is used to contact nearby vessels and in emergencies where there is threat to life or property. The calling or hailing channel 9 is used for establishing contact with another vessel as an alternate to channel 16. As channel 16 is often used so frequently that hailing vessels is not practical in some high traffic areas. Contact is made using channel 9 and then switched to another regular channel for exchange of information. Maritime radio users are required to monitor channel 16, it is also advisable to monitor channel 9 and a weather channel as well. To facilitate these requirements, the VHF 725 is equipped with Tri-Watch and Weather Alert features that allow you to engage in regular channel communications and monitor both the emergency channel and the alternate calling channel while also being alerted of severe weather conditions. Appendix C on pages 28 and 29 of this manual provides a listing of channels and the use of each, including those which are for receiving broadcast messages only. GETTIN. STARTE. Maritime Radio Services Operation Here is a grouping of the channels and a brief description of their use. Channels 5, 12, 14, 20, 65, 66, 73, 74, 77: Port Operations - Can be used by any vessel for communications between ships and ship-tocoast stations for messages relating to operational handling, movement and safety of vessels in or near ports, locks or waterways. Channel 77 is limited to communications to and from commercial pilots in regard to movement and docking of vessels. Channels 11,12, 13, and 14 are used for traffic service on the Great Lakes, St. Lawrence Seaway and designated major ports. Channel 6: Intership Safety - For use by any vessel for communicating navigational and weather warnings to other ships. Also used for communicating with the U.S. Coast Guard during search and rescue operations. Ship-to- ship communications only. Do not use for routine communications as this is a safety channel. Channels 7, 8, 9, 10, 11, 18, 19, 67, 79, 80, 88: Commercial Vessels - Used for communication between vessels pertaining to the purpose for which the vessel is used. Limited communications between vessels and coast stations. Recreational boats are not permitted to use these channels. Channels 8, 67, and 88 may not be used for ship-to-coast communications. Channel 88 is not available on the Great Lakes and St. Lawrence Seaway. Channels 9, 68, 69, 71, 72, 78: non-Commercial (Boat Operations) - Used by recreational boaters and others not engaged in commercial transport. Provides a communication channel pertaining to the needs of the vessel (maneuvers, berthing, provisioning, fueling, etc.). Used as a second receiver between ship-to-ship and ship-to-limited coast stations. Channel 72 may not be used for ship-to-coast communications and channel 9, the alternate calling channel, is shared with commercial vessels. GETTIN. STARTE. Maritime Radio Services Operation Channel 13: Navigation - used by any vessel for safety communications regarding the maneuvering of vessels or directing of a vessels movements. Ship-to-ship and secondarily ship-to-coast communications. Commonly called the Bridge-to-Bridge channel. For routine operations, radio power must be reduced to one watt. Channel 15: Environmental - Used by any vessel to receive only broadcast information concerning environmental conditions in which vessel operate, such as, weather, sea conditions, time signals, and 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...
