| Sailboat, average (6 kn) | 33d 18h |
| Displacement trawler (8 kn) | 25d 7h |
| Fast trawler (10 kn) | 20d 6h |
| Planing motor yacht (15 kn) | 13d 12h |
| Fast motor yacht (20 kn) | 10d 3h |
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.
