How to Track Any Vessel — Complete Guide

Step 1: Identify the ship

Every vessel has three identities. The name is memorable but not unique — dozens of ships may share it. The IMO number is a permanent seven-digit identity that follows the hull through name and flag changes, making it the gold standard for tracking a specific ship. The MMSI is the nine-digit radio identity used in AIS broadcasts; it changes if the ship reflags. If you have any one of these, the vessel search will find the ship.

Step 2: Read the AIS profile

A live position is just the start. Check the speed (a tanker at 12–14 knots is transiting; below 1 knot it's anchored or drifting), the draught (deep means laden, shallow means ballast), the declared destination and ETA, and the course relative to the traffic lanes. Together these tell you what the ship is doing, not just where it is.

Step 3: Follow the route

Movement trails on the live map show a vessel's recent track. In the Strait of Hormuz, transiting ships follow the traffic separation scheme's inbound or outbound lane around the Musandam Peninsula — described in detail in our shipping lanes guide. Deviations from lane discipline, sudden stops, or loops outside the anchorage areas are all worth a second look.

Step 4: Interpret the behaviour

Common patterns: ships circling slowly off Fujairah are waiting for orders or bunkers; a laden tanker with destination "FOR ORDERS" hasn't been sold yet; clusters of stopped vessels at a strait entrance suggest a disruption; an AIS track that jumps hundreds of miles indicates interference or spoofing. Context pages like the strait status tracker help you separate routine from remarkable.
