Draught is reported in the range of 0 to 25,5 metres. The value 0 = not
available (default), and the value 25,5 indicates that the draught is
25,5 metres or more. Only values from 0 to 25,5 shall be accepted by
the AIS. A null field indicates that this is unchanged.
Number of persons on-board includes the crew. The value 0 = not
available (default). The value 8191 = 8191 or more people. Only
values from 0 to 8191 shall be accepted by the AIS. A null field
indicates that this is unchanged.
The characters that can be used in the destination are listed in the ITU-
R M.1371, table 14 (6-bit ASCII). Some of the acceptable characters
in this 6-bit ASCII table are reserved characters under IEC 61162-1.
They must be represented using the "^-method" (See IEC 61162-1,
section 5.1.3.). A null field indicates that the previously entered
destination is
"@@@@@@@@@@@@@@@@@@@@" are used to indicate
that the ship's destination is not available.
The UTC time of arrival field follows the "TIME" field type described
in table 6 (IEC 61162-1). The two fixed digits of seconds are not
broadcast by the AIS and should be set to "00". The optional decimal
point and associated decimal fraction shall not be provided. The
resulting time is a number with six fixed digits, "hhmm00". Leading
zeros are always included for the hours and minutes. If the hour of
arrival is not available, "hh" shall be set to 24. If the minute of arrival
is not available, "mm" shall be set to 60. A null field indicates that this
is unchanged.
The day and month of arrival are in UTC. The day is a two-digit fixed
number requiring leading zeros. The month is a two-digit fixed
number requiring leading zeros. If the day of arrival is not available,
"00" shall be the number for day. If the month of arrival is not
available, "00" shall be the number for the month. A null field
indicates that this is unchanged.
The Navigational status is indicated using the following values, a null
field indicates the status is unchanged (ref. ITU-R M.1371, Message
1, Navigational status parameter):
0 = under way using engine
1 = at anchor
2 = not under command
3 = restricted manoeuvrability
4 = constrained by draught
5 = moored
6 = aground
7 = engaged in fishing
8 = under way sailing
