That is about 65% longer than the direct great-circle line, because the practical route follows coastlines and shipping lanes.
Voyage time by boat speed
Time underway is distance divided by speed. These are continuous-passage figures with no stops or weather margin.

|---|---|
| Sailboat, conservative (5 kn) | 79d 13h |
| Sailboat, average (6 kn) | 66d 7h |
| Displacement trawler (8 kn) | 49d 17h |
| Fast trawler (10 kn) | 39d 19h |
| Planing motor yacht (15 kn) | 26d 12h |
| Fast motor yacht (20 kn) | 19d 21h |
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 Lisboa by sea?
About 9,547 nautical miles (17,682 km / 10,987 statute miles) along the practical sea route, which transits Strait of Gibraltar and Suez Canal and Bab-el-Mandeb and Strait of Malacca. The straight-line distance is shorter, but boats follow coastlines, channels, and traffic lanes.
How long does it take to sail from Lisboa to Shanghai?
At a typical sailing average of 6 knots it is about 66d 7h underway. A 10-knot trawler needs about 39d 19h, and a 20-knot motor yacht about 19d 21h. 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.
