| Sailboat, average (6 kn) | 59d 3h |
| Displacement trawler (8 kn) | 44d 8h |
| Fast trawler (10 kn) | 35d 11h |
| Planing motor yacht (15 kn) | 23d 16h |
| Fast motor yacht (20 kn) | 17d 18h |
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.
