Sea distance from Jeddah to Busan
The sea route from Jeddah (Saudi Arabia) to Busan (South Korea) is about 6,955 nautical miles, which is 12,880 km or 8,003 statute miles. The route transits Bab-el-Mandeb and Strait of Malacca. That is about 49% 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) | 57d 23h |
| Sailboat, average (6 kn) | 48d 7h |
| Displacement trawler (8 kn) | 36d 5h |
| Fast trawler (10 kn) | 29d 0h |
| Planing motor yacht (15 kn) | 19d 8h |
| Fast motor yacht (20 kn) | 14d 12h |
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 Jeddah 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 Jeddah by sea?
About 6,955 nautical miles (12,880 km / 8,003 statute miles) along the practical sea route, which transits 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 Jeddah to Busan?
At a typical sailing average of 6 knots it is about 48d 7h underway. A 10-knot trawler needs about 29d 0h, and a 20-knot motor yacht about 14d 12h. 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.
