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) | 19d 21h |
| Sailboat, average (6 kn) | 16d 13h |
| Displacement trawler (8 kn) | 12d 10h |
| Fast trawler (10 kn) | 9d 22h |
| Planing motor yacht (15 kn) | 6d 15h |
| Fast motor yacht (20 kn) | 4d 23h |
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 Marseille from Hamburg by sea?
About 2,383 nautical miles (4,414 km / 2,743 statute miles) along the practical sea route, which transits Kiel Canal and Strait of Dover and Strait of Gibraltar. 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 16d 13h underway. A 10-knot trawler needs about 9d 22h, and a 20-knot motor yacht about 4d 23h. 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.
