Title 47 › Chapter CHAPTER 5— - WIRE OR RADIO COMMUNICATION › Subchapter SUBCHAPTER III— - SPECIAL PROVISIONS RELATING TO RADIO › Part Part II— - Radio Equipment and Radio Operators On Board Ship › § 351
It is illegal for ships to go out to the open sea or try to leave a U.S. port for the open sea unless they have the required working radio gear and proper crews, unless another rule says there is an exception. Except for cargo ships under 300 gross tons, U.S. and foreign ships must have an efficient radio station that is run by one or more radio officers or operators, properly installed and protected so it works and is safe, and U.S. ships must have a valid station license. Passenger ships of any size and cargo ships of 1,600 gross tons and up must have a radiotelegraph station. Cargo ships of 300 gross tons up to but less than 1,600 gross tons must have a radiotelephone station unless they already have a radiotelegraph. Ships of 1,600 gross tons and up must also have approved radio direction-finding equipment in working order. A ship that was not covered by these rules when it left port does not become covered just because it had to change course or voyage because of bad weather or other things beyond the captain’s, owner’s, or charterer’s control.
