| Sailboat, conservative (5 kn) | 61d 0h |
| Sailboat, average (6 kn) | 50d 20h |
| Displacement trawler (8 kn) | 38d 3h |
| Fast trawler (10 kn) | 30d 12h |
| Planing motor yacht (15 kn) | 20d 8h |
| Fast motor yacht (20 kn) | 15d 6h |
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.
