| Sailboat, conservative (5 kn) | 66d 0h |
| Sailboat, average (6 kn) | 55d 0h |
| Displacement trawler (8 kn) | 41d 6h |
| Fast trawler (10 kn) | 33d 0h |
| Planing motor yacht (15 kn) | 22d 0h |
| Fast motor yacht (20 kn) | 16d 12h |
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.
