The sea takes.
You bring
them home.

Keep the light.
Keep them alive.

Guide all three vessels into harbour before the three-minute watch ends.

1. Select a vessel. Tap its name in the fleet panel or its marker on the sea. The beam will follow it.
2. Restore its course. A vessel in your light recovers slowly. In darkness, and harder in the fog, its course falls toward the reef. At zero, it is lost.
3. Share the light. Switch to the vessel with the lowest course. The small lower bar shows its journey home.
4. Sound the foghorn. It holds everyone safely for six seconds. In the fog, it is how you keep the third vessel. It needs 24 seconds to recover.
