| Sailboat, average (6 kn) | 71d 10h |
| Displacement trawler (8 kn) | 53d 13h |
| Fast trawler (10 kn) | 42d 20h |
| Planing motor yacht (15 kn) | 28d 13h |
| Fast motor yacht (20 kn) | 21d 10h |
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.

At a typical sailing average of 6 knots it is about 71d 10h underway. A 10-knot trawler needs about 42d 20h, and a 20-knot motor yacht about 21d 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.
