Safety messages the ship broadcast to everyone nearby over AIS, word for word, from the last 30 days. Written by the crew; most ships rarely send them.

The ship’s own AIS radio broadcast, picked up by a receiver on land shared with AISHub by its owner. Land receivers hear ships up to about 40–70 km out. It reached us through Open Waters, which gathers AIS from many receivers.

What do these mean?

Heard: Ships send their position by radio (AIS) every few seconds to minutes. Receivers on land pick it up, so a ship far out at sea isn’t heard until it nears a coast.
Knots (kn): How ships measure speed. 1 knot is 1.85 km/h or 1.15 mph, so 10 knots is about 19 km/h (12 mph).
Working, can’t move freely: What cable ships report while laying or repairing cable: they’re holding a line or a position and can’t easily get out of the way.
Stopped at sea: Engines on but not moving, often holding position while working.
Track on the map: Solid blue where the ship was heard. Grey dots where it went quiet for more than half an hour: an estimate of its route from where it was last heard to where it was heard again, following the usual sea lanes round any land. The real path isn’t known.
Turning: How fast the ship is changing direction, as it reports it: “holding course” when it isn’t. Only while it’s moving.
Messages from the ship: Short safety notices the crew broadcast to every ship nearby, such as asking others to keep clear while they work.
Heading / Facing: Which way the ship is moving, and which way its front points when it is stopped.
Draught: How deep the bottom of the ship sits below the water line.
IMO / MMSI: A ship’s permanent ID, and the number its radio uses. The MMSI’s first three digits show the country it’s registered in.
Doing / Heading to: Typed in by the crew, so it can be out of date. Cable ships often type an activity instead, like “CABLE OPS” (cable work at sea).
