| Sailboat, average (6 kn) | 37d 23h |
| Displacement trawler (8 kn) | 28d 11h |
| Fast trawler (10 kn) | 22d 19h |
| Planing motor yacht (15 kn) | 15d 4h |
| Fast motor yacht (20 kn) | 11d 9h |
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.

How is this distance calculated?
It is computed over the open Eurostat global shipping-lane network, the same kind of network freight routing tools use. It is a realistic planning estimate, not a navigation product: your sailed distance will vary with weather routing, draft, and the exact harbors you use.
