Voyage time by boat speed
Time underway is distance divided by speed. These are continuous-passage figures with no stops or weather margin.
| Boat and speed | Time underway |
|---|---|
| Sailboat, conservative (5 kn) | 9d 10h |
| Sailboat, average (6 kn) | 7d 20h |
| Displacement trawler (8 kn) | 5d 21h |
| Fast trawler (10 kn) | 4d 17h |
| Planing motor yacht (15 kn) | 3d 3h |
| Fast motor yacht (20 kn) | 2d 8h |
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.

How far is Lisboa from Antwerpen by sea?
About 1,129 nautical miles (2,091 km / 1,299 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 Antwerpen to Lisboa?
At a typical sailing average of 6 knots it is about 7d 20h underway. A 10-knot trawler needs about 4d 17h, and a 20-knot motor yacht about 2d 8h. 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.
