What information do you show for each ship?

Each ship profile includes live position on a map, current speed and heading, detailed specifications (tonnage, length, passenger capacity), photo galleries, operator information, and historical voyage data.

How accurate are the live positions?

AIS positions are generally accurate to within a few hundred meters. However, there can be brief delays between a ship's actual position and what's displayed, depending on AIS signal reception conditions and data processing time.

Frequently Asked Questions

Everything you need to know about tracking cruise ships online.

How does cruise ship tracking work?+

We use AIS (Automatic Identification System) data — the same transponder technology used by maritime authorities worldwide. Every large vessel broadcasts its position, speed, and heading via radio signals, which we collect and display on our interactive map in near real-time.

Is CruiseShipTracking.com free to use?+

Yes, completely free. You can track any cruise ship, explore ports, compare vessels, and read our cruise guides without creating an account or paying anything.

How often are ship positions updated?+

Ship positions are updated every few minutes via live AIS data feeds. The frequency depends on the vessel's location and signal availability — ships near coastlines update more frequently than those in open ocean.
