| Sailboat, average (6 kn) | 55d 16h |
| Displacement trawler (8 kn) | 41d 18h |
| Fast trawler (10 kn) | 33d 10h |
| Planing motor yacht (15 kn) | 22d 6h |
| Fast motor yacht (20 kn) | 16d 17h |
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.
