Cruiser's Maritime Mobile Radio Nets
Marine radio nets are set up and run by "controllers" all over the world (Indian Ocean, Atlantic, Mediterranean, Pacific, etc.) to handle and co-ordinate this traffic from vessels sailing the oceans. It is important for cruising yachts to know these radio net frequencies and times so as to pass message traffic, log positions, receive weather information, etc.
Amateur radio unless otherwise noted. Please listen first to note the procedures of each net.
