  • Mal-de-mar

    nausea and dizziness, sometimes accompanied by vomiting, resulting from the rocking or swaying motion of a vessel in which one is traveling at sea.
  • MMSI

    Maritime Mobile Service Identity The nine-digit MMSI number is a bit like a phone number for your boat and is used by maritime Digital Selective Calling (DSC), Automatic Identification Systems (AIS) and certain other equipment to uniquely identify a ship or a coast radio station. All DSC capable equipment (including AIS units) associated with the specific vessel should use the same MMSI number, since the MMSI serves to identify the vessel, not the equipment.
