|---|---|
| Sailboat, conservative (5 kn) | 50d 4h |
| Sailboat, average (6 kn) | 41d 19h |
| Displacement trawler (8 kn) | 31d 8h |
| Fast trawler (10 kn) | 25d 2h |
| Planing motor yacht (15 kn) | 16d 17h |
| Fast motor yacht (20 kn) | 12d 13h |
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.
