Sea distance from Shanghai to Busan
The sea route from Shanghai (China) to Busan (South Korea) is about 460 nautical miles, which is 853 km or 530 statute miles. That is about 3% 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.
| Boat and speed | Time underway |
|---|---|
| Sailboat, conservative (5 kn) | 3d 20h |
| Sailboat, average (6 kn) | 3d 5h |
| Displacement trawler (8 kn) | 2d 10h |
| Fast trawler (10 kn) | 1d 22h |
| Planing motor yacht (15 kn) | 1d 7h |
| Fast motor yacht (20 kn) | 23h |
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 Busan 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 Busan from Shanghai by sea?
About 460 nautical miles (853 km / 530 statute miles) along the practical sea route. The straight-line distance is shorter, but boats follow coastlines, channels, and traffic lanes.
How long does it take to sail from Shanghai to Busan?
At a typical sailing average of 6 knots it is about 3d 5h underway. A 10-knot trawler needs about 1d 22h, and a 20-knot motor yacht about 23h. 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.
