   Categories of ships. (1) When referenced in Part II of Title III of the
   Communications Act or the radio provisions of the Safety Convention, a ship
   is a passenger ship if it carries or is licensed or certificated to carry
   more than twelve passengers. A cargo ship is any ship not a passenger ship.

   (2) A commercial transport vessel is any ship which is used primarily in
   commerce (i) for transporting persons or goods to or from any harbor(s) or
   port(s)  or  between  places  within a harbor or port area, or (ii) in
   connection  with  the construction, change in construction, servicing,
   maintenance, repair, loading, unloading, movement, piloting, or salvaging of
   any other ship or vessel.

   (3) The term passenger carrying vessel, when used in reference to Part III,
   Title III of the Communications Act of the Great Lakes Radio Agreement,
   means any ship transporting more than six passengers for hire.

   (4) Power-driven vessel. Any ship propelled by machinery.

   (5)  Towing vessel. Any commercial ship engaged in towing another ship
   astern, alongside or by pushing ahead.

   (6)  Compulsory  ship.  Any ship which is required to be equipped with

   aboard commercial transport vessels, which relate directly to the purposes
   for which the ship is used including the piloting of vessels, movements of
   vessels, obtaining vessel supplies, and scheduling of repairs.

   Day. (1) Where the word day is applied to the use of a specific frequency
   assignment or to a specific authorized transmitter power, its use means
   transmission on the frequency assignment or with the authorized transmitter
   power during that period of time included between one hour after local
   sunrise and one hour before local sunset.

   (2) Where the word day occurs in reference to watch requirements, or to
   equipment  testing,  its  use means the calendar day, from midnight to
   midnight, local time.

   Digital selective calling (DSC). A synchronous system developed by the
   International Telecommunication Union Radiocommunication (ITU-R) Sector,
   used to establish contact with a station or group of stations automatically
   by means of radio. The operational and technical characteristics of this
   system are contained in ITU-R M.493-13 and ITU-R M.541-9 (both incorporated
   by reference, see § 80.7) (see subpart W of this part.)

   signals and taking bearings on these signals from which the true bearing and
   direction of the point of origin may be determined.

   Distress signal. The distress signal is a digital selective call using an
   internationally  recognized distress call format in the bands used for
   terrestrial communication or an internationally recognized distress message
   format, in which case it is relayed through space stations, which indicates
   that a person, ship, aircraft, or other vehicle is threatened by grave and
   imminent danger and requests immediate assistance.

   (1) In radiotelephony, the international distress signal consists of the
   enunciation  of the word “Mayday”, pronounced as the French expression
   “m'aider”. In case of distress, transmission of this particular signal is
   intended to ensure recognition of a radiotelephone distress call by stations
   of any nationality.

   (2)  For  GMDSS, distress alerts result in an audible alarm and visual
   indication that a ship or person is threatened by grave and imminent danger
   and  requests  immediate  assistance.  These automatic systems contain
   sufficient information in the distress alert message to identify the vessel,
   prepare to assist and begin a search. However, except when transmitted via
   satellite EPIRB, the distress alert is just the initial call for help.
   Communication  between the vessel or person in distress and the Rescue
   Coordination Center (RCC) or ship assisting should always follow.

   system includes standardized equipment and operational procedures, unique
   identifers for each station, and the integrated use of frequency bands and
   radio systems to ensure the transmission and reception of distress and
   safety calls and messages at short, medium and long ranges.
