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.

Frequently asked questions

How far is Durban from Rotterdam by sea?

About 7,077 nautical miles (13,106 km / 8,144 statute miles) along the practical sea route, which transits Strait of Dover. The straight-line distance is shorter, but boats follow coastlines, channels, and traffic lanes.

How long does it take to sail from Rotterdam to Durban?

At a typical sailing average of 6 knots it is about 49d 4h underway. A 10-knot trawler needs about 29d 12h, and a 20-knot motor yacht about 14d 18h. Add margin for weather, currents, and stops.

How is this distance calculated?

It is computed over the open Eurostat global shipping-lane network, the same kind of network freight routing tools use. It is a realistic planning estimate, not a navigation product: your sailed distance will vary with weather routing, draft, and the exact harbors you use.
