Here"s a recent article by Chuck Hawley/US Sailing

Being able to communicate with other boaters and rescue agencies makes having a VHF a necessity no matter how small your boat.

Your VHF radio should be your go-to communications in an emergency. The U.S. Coast Guard has a huge network of towers to listen in on distress calls and when you make a call, every other nearby boater with a radio on can also hear you, which increases your chance of getting help. Knowing a little about your VHF and how to make the call can help when you really need it.

Fixed-Mount VHF Radios

Arguably one of the most cost-effective safety items you can have on any boat, a fixed-mount VHF allows you to communicate with a wide range of people and organizations: the U.S. Coast Guard, commercial ships, the Rescue 21 network, bridge tenders, TowBoatUS, race committees, and countless others stations. And its full potential is realized when units with Digital Selective Calling, or DSC, are connected to an operational GPS receiver (or have one internally). While all radios sold in the U.S. over the last decade are equipped with DSC, many operators (the U.S. Coast Guard says about 85 percent) either have not connected their radios to their GPS, nor registered for an MMSI (Marine Mobile Service Identity) number. This is vital for the full functionality of the Rescue 21 system.

Fixed-mount VHF radios are only as good as their antenna systems (a combination of the antenna, coaxial cable, and connections). Antennas should be mounted as high as possible: on the masthead of a sailboat or on the flybridge of a powerboat. Because VHF signals travel more or less in a straight line, a higher antenna will allow a VHF signal to reach more distant stations due to the Earth's curvature.

The Invaluable Phonetic Alphabet

To make sure you're clearly understood, especially when using the VHF radio, words often need to be spelled out using what's known as the phonetic alphabet. On a radio transmission, static can produce mistakes. For instance, over the past couple of years, a popular boat name, according to our BoatUS records, has been Blew By You. In audio communications, this can be mistaken for Blue Bayou. Learn the phonetic alphabet by heart so that you can easily spell out names and words quickly, especially in emergency situations.
