| Sailboat, average (6 kn) | 73d 10h |
| Displacement trawler (8 kn) | 55d 1h |
| Fast trawler (10 kn) | 44d 1h |
| Planing motor yacht (15 kn) | 29d 9h |
| Fast motor yacht (20 kn) | 22d 1h |
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.
