註釋

Because the single sideband radio (SSB) has a worldwide range, it is an essential piece of equipment aboard any serious oceangoing boat. Thus equipped, such a vessel can raise an alarm in mid-ocean, talk to other vessels, receive faxes, and "plug in" to the telephone network on any shore. This guide assumes no previous knowledge, but takes the reader through the information needed to earn an operators license. Also included is a primer on the Global Maritime Distress & Safety System (GMDSS), the new technology which automatically alerts rescue services via radio and satellite.
