| Fast motor yacht (20 kn) | 10d 11h |
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.

About 5,026 nautical miles (9,307 km / 5,783 statute miles) along the practical sea route, which transits Corinth Canal and Strait of Gibraltar. The straight-line distance is shorter, but boats follow coastlines, channels, and traffic lanes.

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.
