Vessel Class Finder

Vessel Class Finder

Check any ship's class status by IMO, via API or in Claude

2 followers

A free lookup and JSON API for the IACS Vessels in Class dataset. Enter a ship's IMO number to see its classification society, class status (in class, suspended or withdrawn), last and next survey dates, and why its status last changed. IACS only publishes this as a ZIP/CSV download; we refresh it weekly. Check up to 100 ships per request, or ask Claude directly through our MCP connector. Free: 100 lookups/month, paid plans from $49.
