|---|---|
| Sailboat, conservative (5 kn) | 54d 10h |
| Sailboat, average (6 kn) | 45d 8h |
| Displacement trawler (8 kn) | 34d 0h |
| Fast trawler (10 kn) | 27d 5h |

| Fast motor yacht (20 kn) | 13d 15h |
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.
