Her MMSI

235070759

The first three digits, 235, are the country code of the United Kingdom: an MMSI follows a ship's flag, so a new flag brings a new number.

Her IMO number, 9533402, stays with the hull for life.

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 AWorked out, not reported: only Class A transponders send a status, and she sends one. Class A is the full-strength kind that large cargo and passenger ships must carry.

To the bow	15 m (A)
To the stern	14 m (B)
