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 › § 351
Unless section 352 says otherwise, certain ships may not go out on the open sea or leave a U.S. port for the open sea unless they have working radio equipment and, for U.S. ships, a valid station license. Passenger ships of any size and cargo ships of 1,600 gross tons or more must have a radiotelegraph station that meets the rules. Cargo ships from 300 up to 1,600 gross tons must have a radiotelephone station unless they already have a radiotelegraph. Cargo ships under 300 gross tons are exempt. Ships of 1,600 gross tons or more must also carry radio direction-finding gear approved by the Commission. Radios must be properly installed, protected, kept in operating condition, and operated by one or more radio officers or operators. A ship that was not covered by these rules when it left port does not become covered because it changed course due to weather or other causes beyond the master’s, owner’s, or charterer’s control.
