| Planing motor yacht (15 kn) | 29d 21h |
| Fast motor yacht (20 kn) | 22d 10h |
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 10,756 nautical miles (19,920 km / 12,378 statute miles) along the practical sea route, which transits Strait of Malacca. 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.
