|---|---|
| Sailboat, conservative (5 kn) | 51d 22h |
| Sailboat, average (6 kn) | 43d 7h |
| Displacement trawler (8 kn) | 32d 11h |
| Fast trawler (10 kn) | 25d 23h |
| Planing motor yacht (15 kn) | 17d 7h |
| Fast motor yacht (20 kn) | 13d 0h |
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.
