Vessel Tracker

Live ship positions and AIS data

Vessel Tracker tracks any ship in real time using live AIS data broadcast from vessels worldwide. Whether you're monitoring a specific ship by its MMSI number or watching all traffic in a busy port, you get current positions, speeds, headings, and navigation status within seconds.

The tool taps into global automatic identification system data — the same signals ships transmit to each other to avoid collisions. It covers commercial vessels, tankers, cargo ships, ferries, tugs, and pleasure craft anywhere in the world.

What you can do

  • search_vessels — find vessels by MMSI or geographic bounding box, with live positions and speeds
  • vessel_details — get static ship specs like name, type, flag, dimensions, and call sign
  • monitor_area — full traffic report for a port or sea area showing all active vessels
  • safety_alerts — active collision warnings, weather broadcasts, and distress signals for an area
  • navigation_aids — buoys, beacons, and navigational markers, flagging any that appear off position
  • visualize_area — AI-generated bird's-eye map showing vessel positions in a geographic area

Who it's for

Maritime logistics teams tracking shipments, port authorities monitoring traffic, security analysts watching specific vessels, and researchers studying shipping patterns. Also useful for anyone curious about what ships are passing through a particular stretch of water.

How to use it

  1. Use search_vessels with an MMSI number to track a specific ship, or pass a bounding box to see all vessels in an area
  2. Use vessel_details to get the ship's static profile — name, type, flag, and dimensions
  3. Use monitor_area for a comprehensive traffic report on a port or channel
  4. Use safety_alerts to check for active distress signals or hazard broadcasts
  5. Use visualize_area to generate a visual map of vessel positions

Getting started

Connect your AISStream account to enable live data. Common bounding boxes: English Channel [49.5,-5.5]-[51.5,2.0], Singapore Strait [1.1,103.5]-[1.5,104.2], Port of Rotterdam [51.85,3.9]-[52.0,4.2].

Search Vessels

Find vessels by MMSI or bounding box. Returns latest position, speed, course, heading, and navigation status. Collects live AIS position reports for ~15 seconds, deduplicated by vessel.

Returns: Real-time vessel positions with speed, course, heading, and navigation status
Vessel Details

Get vessel specs: name, call sign, IMO, ship type, dimensions, destination, ETA, draught. Listens for static broadcasts (~6 min intervals) so takes longer than position lookups. Also captures position data.

Returns: Vessel profiles with name, type, dimensions, destination, ETA, and current position
Monitor Area

Comprehensive traffic report for a geographic area. Collects all AIS message types and aggregates into a summary with vessel counts, moving vs stationary breakdown, vessel types, and safety alerts.

Returns: Area traffic report with vessel positions, movement statistics, and safety alerts
Safety Alerts

Listen for safety broadcasts in a geographic area: collision warnings, weather advisories, distress signals, and navigational warnings. Captures broadcast and addressed messages. Useful for risk assessment.

Returns: Maritime safety messages with alert text, source vessel, position, and timestamp
Navigation Aids

Find buoys, beacons, lighthouses, and other navigation aids (AtoN) in a geographic area. Returns type, position, dimensions, virtual/physical status. Flags off-position aids for safe navigation.

Returns: Navigation aids inventory with type, position, virtual/physical status, and off-position alerts
Visualize Area

Generate a bird's-eye satellite or radar-style image of live vessel positions in a geographic area. Collects AIS data, categorizes by status, then produces an AI visualization with vessel markers.

Returns: AI-generated bird's-eye map image with vessel positions, plus structured vessel data

Frequently Asked Questions

Can I track a specific ship or watch an area?

`search_vessels` finds a vessel by MMSI or bounding box, and `monitor_area` returns a fuller traffic report for a region.

Why does vessel details take longer?

`vessel_details` listens for static broadcasts, so it can take longer than a live position lookup, but it adds ship specs like IMO, dimensions, destination, and ETA.

Can I see safety warnings or navigational hazards?

Yes. `safety_alerts` surfaces collision, weather, distress, and navigational broadcasts, and `navigation_aids` finds buoys, beacons, and lighthouses.

Can I get a map-style view of traffic?

`visualize_area` generates a bird's-eye view with AIS vessel markers for the area you choose.
