Documented journeys explain why ships were built. Received AIS reports show a much narrower thing: positions this site has actually heard.
Gold dashed lines connect documented places. They are schematic connections, may cross land, and are not reconstructed sailing tracks. Location markers use approximate port or area coordinates.
Cunard’s archived M402 itinerary connects New York and Southampton. This is one documented crossing, not a claim that the ship only sails this route. The line on the map connects ports and does not reproduce the ocean track or today’s itinerary.

The British inquiry describes Southampton, Cherbourg and Queenstown, now Cobh, on the maiden voyage. The route ends here at the last port call. Titanic was lost in the North Atlantic; New York was the intended destination, not an arrival. No invented sinking-to-port track is drawn.
Departure on 10 April 1912.
French call on 10 April 1912.
Last port call on 11 April 1912.
November 2023 to January 2024 (2023-11 to 2024-01)
Icon was delivered at Turku before beginning its first revenue cruise from Miami on 27 January 2024. These are two documented milestones connected schematically. Intermediate calls, delivery stops and the exact Atlantic route are not reconstructed.
Meyer Turku construction and delivery.
Starting port for the first revenue cruise.
23–29 March 2021 (2021-03-23 to 2021-03-29)
The flag-state investigation records the northbound canal passage and grounding. The salvage announcement documents refloating on 29 March. Markers locate the southern entrance, the grounding area and Great Bitter Lake for geographical context; the line is not a reconstruction of helm orders or AIS.
Northbound entry area.
Approximate location, not a surveyed grounding plan.
Lake used after refloating.
Delivery tow began June 2017 (2017-06)
TechnipFMC documented Prelude leaving Geoje for Australia. The destination marker shows the approximate offshore development area, not a port. Prelude’s work is processing gas offshore; the map does not portray it as a liner or a self-propelled tanker.
Construction yard and tow departure.
Approximate development area.
Built 1979; recycled 2010
Seawise Giant was built at Yokosuka in Japan and ultimately dismantled at Alang in India. Its intervening life included crude transport and later floating storage in the Persian Gulf. These endpoints summarize its life cycle; the connection is not a direct voyage or a complete itinerary.
Construction at Sumitomo Heavy Industries.
Final recycling location.
Sampled reports from the existing AIS receiver, kept for up to seven days. Collection starts with this feature’s deployment. Old voyages cannot be replayed and missing reports are never filled in.
Checking recorded positions…
Up to one sample every 30 minutes. Points are reception events, not guaranteed fix times. Lines connect consecutive samples only when the gap is no longer than 90 minutes and implied movement is plausible. A straight segment does not prove the ship’s path between reports.
