| Sailboat, average (6 kn) | 67d 19h |
| Displacement trawler (8 kn) | 50d 21h |
| Fast trawler (10 kn) | 40d 16h |
| Planing motor yacht (15 kn) | 27d 3h |
| Fast motor yacht (20 kn) | 20d 8h |
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 9,764 nautical miles (18,082 km / 11,236 statute miles) along the practical sea route, which transits Sunda Strait. The straight-line distance is shorter, but boats follow coastlines, channels, and traffic lanes.

At a typical sailing average of 6 knots it is about 67d 19h underway. A 10-knot trawler needs about 40d 16h, and a 20-knot motor yacht about 20d 8h. Add margin for weather, currents, and stops.
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.
