§  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.
