|---|---|
| Sailboat, conservative (5 kn) | 70d 12h |
| Sailboat, average (6 kn) | 58d 18h |
| Displacement trawler (8 kn) | 44d 2h |
| Fast trawler (10 kn) | 35d 6h |
| Planing motor yacht (15 kn) | 23d 12h |
| Fast motor yacht (20 kn) | 17d 15h |
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.
