Recommendations for Marine Communication

•

The frequencies your radio uses are set aside to enhance safety afloat and for vessel

navigation and operational messages over a range suitable for nearshore voyages. If

the 5 watt maximum output of your radio is not sufficient for the distances you

travel from the coast, consider installing a CobraMarine fixed mount radio with up to

25 watts of output power. (Visit www.cobra.com or your local dealer for model

availability.)

If traveling far offshore, you should consider adding even more powerful radio

equipment such as HF single side band or satellite radio for your vessel.

The U.S. Coast Guard does not endorse cellular telephones as substitutes for marine

radios. They generally cannot communicate with rescue vessels and, if you make a

distress call on a cellular telephone, only the party you call will be able to hear you.

Additionally, cellular telephones may have limited coverage over water and can be

hard to locate. If you do not know where you are, the Coast Guard will have difficulty

finding you if you are using a cellular telephone.

However, cellular telephones can have a place on board where cellular coverage

is available — to allow social conversations and keep the marine frequencies

uncluttered and available for their intended uses.
