Planning estimate, not navigation

This distance is computed over the open Eurostat shipping-lane network. It is a realistic passage length for planning, but your sailed distance will differ with weather routing, currents, draft, and the exact berths you leave from and arrive at. Always verify against official charts.

Building with these numbers? The sea route & distance API returns this figure, voyage time, and route geometry for any port pair in one GET request.
