Voyage time by boat speed
Time underway is distance divided by speed. These are continuous-passage figures with no stops or weather margin.
| Boat and speed | Time underway |
|---|---|
| Sailboat, conservative (5 kn) | 18d 13h |
| Sailboat, average (6 kn) | 15d 11h |
| Displacement trawler (8 kn) | 11d 14h |
| Fast trawler (10 kn) | 9d 7h |
| Planing motor yacht (15 kn) | 6d 4h |
| Fast motor yacht (20 kn) | 4d 15h |
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.
Plan this passage properly
Open Shanghai to Singapore in the Marine OS route planner: it suggests the sea route, then you drag waypoints, set your speed and fuel burn, and check weather and tides along the way.

How far is Singapore from Shanghai by sea?
About 2,226 nautical miles (4,123 km / 2,562 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 long does it take to sail from Shanghai to Singapore?
At a typical sailing average of 6 knots it is about 15d 11h underway. A 10-knot trawler needs about 9d 7h, and a 20-knot motor yacht about 4d 15h. 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.
