Maritime Radio Service. The user must be cognizant of, and comply with, Part 83 of the FCC Rules and Regulations,

A valid station license is required before operation of the radio is permissible, obtained by submitting a properly and fully
completed FCC Form 506 to the FCC.
The radiotelephone transmitter in a ship station may be operated only by a licensed radio operator. The licensed
operator may permit others to speak into the microphone if he starts, supervises, and ends the operation, makes the
necessary log entries, and gives the necessary identification. The license usually held by radio operators aboard small
vessels not required to carry a radio installation for safety purposes is the Restricted Radiotelephone Operator Permit.
This lifetime permit is obtained by submitting to the FCC a properly and fully completed FCC Form 753. No oral or
written examination is required.
NOTE: It is the responsibility of Canadian residents to comply with all licensing requirements of the DOC, the governing
body for communications equipment in Canada.
The licensee of a ship radio station is responsible at all times for the lawful and proper operation of the station. Ship
stations are licensed primarily for safety of life and property; therefore, distress and safety communications must have
absolute priority. Secondarily, however, certain frequencies which are not reserved for calling, distress, or other safety
purposes may be used for radiotelephone calls to coast stations or between ships.
