Her MMSI

525900644

The first three digits, 525, are the country code of Indonesia: an MMSI follows a ship's flag, so a new flag brings a new number.

She broadcasts no IMO number. Only larger seagoing ships are required to have one.

Her AIS details

AIS is the radio signal a ship sends so that other ships can see her. This is what her signal tells us.

Seen from above, bow to the right, so port is the upper side. The ring is her GPS aerial, where her crew or installer said it sits. Shiptrail draws the aerial's position, not the middle of the ship.

AIS class	Class BWorked out, not reported: only Class A transponders send a status, and she sends none. Class B is the lighter kind on yachts, fishing boats and other small craft, which reports less often.
To the bow	4 m (A)
To the stern	7 m (B)
To the port side	4 m (C)
To the starboard side	4 m (D)
