It for communications beyond the range of VHF (about 20 miles)
Its 'similar' to HAM radio but operates on different assigned frequencies (channels). You need a restricted operators license and a station license to operate a SSB.
However, you can 'listen in' to the various 'marine nets', high seas weather forecasts, weather routers, and the occasional 'chit-chat'. Commonly, SSB communications are 'good' (depending on 'propagation', etc.) for upwards of several thousand miles, sometimes 'around the world'.
SSB 'frequencies" YachtCom - Marine SSB radio | MF frequencies | HF frequencies | SSB Channels .... but the communications can vary with the time of day, propagation strength due to the variability of the ionosphere and 'atmospherics' required to hear or speak with the other stations. With SSB you can also receive (when using auxiliary equipment: text email, weather fax (weather charts), various text weather (from governments), etc. etc.
