|---|---|
| Sailboat, conservative (5 kn) | 92d 12h |
| Sailboat, average (6 kn) | 77d 2h |
| Displacement trawler (8 kn) | 57d 20h |
| Fast trawler (10 kn) | 46d 6h |
| Planing motor yacht (15 kn) | 30d 20h |
| Fast motor yacht (20 kn) | 23d 3h |
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 far is Shanghai from Santos by sea?
About 11,102 nautical miles (20,562 km / 12,776 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 77d 2h underway. A 10-knot trawler needs about 46d 6h, and a 20-knot motor yacht about 23d 3h. 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.
