Title 47 › CHAPTER 5 — WIRE OR RADIO COMMUNICATION › SUBCHAPTER III — SPECIAL PROVISIONS RELATING TO RADIO › Part II — Radio Equipment and Radio Operators On Board Ship › § 357
Ship captains of U.S. vessels that have radios must send out safety information when they meet dangers like dangerous ice, a floating wreck, a tropical storm, any other direct hazard to navigation, very cold air with gale‑force winds that causes heavy ice to build on the ship’s structures, or winds of force 10 or above on the Beaufort scale when no storm warning was received. They must transmit that information to nearby ships and to the proper authorities on land under rules the Commission sets. Those authorities must quickly tell anyone affected, including foreign authorities, when needed. No U.S. mobile ship or station may charge for sending, receiving, or relaying the safety messages described above that come from U.S. or foreign ships. If a station does charge to receive or forward a required message, the ship must not pay and may ask the Commission to reimburse the charge. Distress messages and replies about saving lives or property at sea are also free. Stations or carriers may provide other free safety services (like chart, weather, navigation aid, or medical help) under Commission rules, which can limit such free service if needed for the public interest.
