The legacy application will be retired at the end of August 2018

We need to retire the legacy PortToPort Online application as it relies on an old technology (Microsoft Silverlight).
This application only runs on on Internet Explorer (on Windows) or Safari (on Mac).

Access the legacy PortToPort Online application here.


Features include:

  • Accurate distances
  • Create multi-leg voyages using over 3300 'distance table' ports
  • Full control over routing between ports
  • Distances travelled in ECA zones


Pricing is based on an annual subscription model; users purchase a block of distance calculations that are valid for up to one year. Multiple users can share a subscription. For more details see the Online Store page.
