|---|---|
| Sailboat, conservative (5 kn) | 59d 10h |
| Sailboat, average (6 kn) | 49d 12h |
| Displacement trawler (8 kn) | 37d 3h |
| Fast trawler (10 kn) | 29d 17h |
| Planing motor yacht (15 kn) | 19d 19h |
| Fast motor yacht (20 kn) | 14d 21h |
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.
