Voyage time by boat speed

Time underway is distance divided by speed. These are continuous-passage figures with no stops or weather margin.

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 Marseille from Antwerpen by sea?

About 2,119 nautical miles (3,925 km / 2,439 statute miles) along the practical sea route, which transits Strait of Dover and Strait of Gibraltar. The straight-line distance is shorter, but boats follow coastlines, channels, and traffic lanes.

How long does it take to sail from Antwerpen to Marseille?

At a typical sailing average of 6 knots it is about 14d 17h underway. A 10-knot trawler needs about 8d 20h, and a 20-knot motor yacht about 4d 10h. 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.
