|---|---|
| Sailboat, conservative (5 kn) | 34d 16h |
| Sailboat, average (6 kn) | 28d 21h |
| Displacement trawler (8 kn) | 21d 16h |
| Fast trawler (10 kn) | 17d 8h |
| Planing motor yacht (15 kn) | 11d 13h |
| Fast motor yacht (20 kn) | 8d 16h |
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 28d 21h underway. A 10-knot trawler needs about 17d 8h, and a 20-knot motor yacht about 8d 16h. 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.
