    Hi Dennis

    I looks OK to me. 

    The !PAIS are custom signal not part of the AIVDM protocol. The custom signal, depending on implementation, may be used to report various signal between receiver and e.g. a plotter.

    All messages prefixed with !AIVDM are AIS messages, two types exist, position status and extended status. The extended status are the "long lines"
