|---|---|
| Sailboat, conservative (5 kn) | 43d 2h |
| Sailboat, average (6 kn) | 35d 22h |
| Displacement trawler (8 kn) | 26d 23h |
| Fast trawler (10 kn) | 21d 13h |
| Planing motor yacht (15 kn) | 14d 9h |
| Fast motor yacht (20 kn) | 10d 19h |
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.
