§  80.955   Radiotelephone installation.

   (a) Each U.S. flag vessel of less than 38 meters (124 feet) in length
   while subject to the Great Lakes Agreement must have a radiotelephone
   meeting the provisions of this subpart in addition to the other rules
   in this part governing ship stations using telephony.

   (b) Each U.S. flag vessel of 38 meters (124 feet) or more in length
   while subject to the Great Lakes Agreement must have a minimum of two
   VHF radiotelephone installations in operating condition meeting the
   provisions of this subpart. The second VHF installation must be
   electrically separate from the first VHF installation. However, both
   may be connected to the main power supply provided one installation can
   be operated from a separate power supply located as high as practicable
   on the vessel.

   (c) This paragraph does not require or prohibit the use of other
   frequencies for use by the same “radiotelephone installation” for
   communication authorized by this part.
