§ 80.1087   Ship radio equipment—Sea area A1.

   This section contains the additional equipment requirements for ships that
   remain within sea area A1 at all times.

   (a) In addition to meeting the requirements of § 80.1085, ships engaged on
   voyages  exclusively  in  sea  area  A1  must be provided with a radio
   installation  capable  of initiating the transmission of ship-to-shore
   distress alerts from the position from which the ship is normally navigated,
   operating either:

   (1) On VHF using DSC; or

   (2) Through the polar orbiting satellite service on 406.0-406.1 MHz (this
   requirement may be fulfilled by the EPIRB required by § 80.1085(a)(6), either
   by installing the EPIRB close to, or by allowing remote activation from, the
   position from which the ship is normally navigated); or

   (3) On MF using DSC if the ship is engaged on voyages within coverage of MF
   coast stations equipped with DSC; or

   (4) On HF using DSC; or

   (5) Through the INMARSAT geostationary satellite service if within INMARSAT
   coverage.  This requirement may be fulfilled by an INMARSAT ship earth
   station capable of two way communication.

   (b) The VHF radio installation, required by § 80.1085(a)(1), must also be
   capable of transmitting and receiving general radiocommunications using
   radiotelephony.
