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) | 4d 7h |
| Sailboat, average (6 kn) | 3d 14h |
| Displacement trawler (8 kn) | 2d 16h |
| Fast trawler (10 kn) | 2d 4h |
| Planing motor yacht (15 kn) | 1d 10h |
| Fast motor yacht (20 kn) | 1d 2h |
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 Le Havre from Hamburg by sea?
About 515 nautical miles (953 km / 592 statute miles) along the practical sea route, which transits Kiel Canal and Strait of Dover. The straight-line distance is shorter, but boats follow coastlines, channels, and traffic lanes.

At a typical sailing average of 6 knots it is about 3d 14h underway. A 10-knot trawler needs about 2d 4h, and a 20-knot motor yacht about 1d 2h. 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.
