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
Most ships may not leave a U.S. port for a sea voyage unless they have the required radio equipment and at least one trained radio officer on board. There are exceptions listed elsewhere in the law. Passenger ships of any size and cargo ships of 1,600 gross tons or more must have a radiotelegraph station. 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. U.S. ships must have a valid station license. All equipment must work, be properly installed and protected, and be operated by qualified radio personnel. If a ship was not covered by these rules when it left port, it does not become covered just because it had to change course or plan because of weather or other things beyond the master’s, owner’s, or charterer’s control.
