|---|---|
| Sailboat, conservative (5 kn) | 45d 14h |
| Sailboat, average (6 kn) | 38d 0h |
| Displacement trawler (8 kn) | 28d 12h |
| Fast trawler (10 kn) | 22d 19h |

| Fast motor yacht (20 kn) | 11d 10h |
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 Los Angeles 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.
