| Sailboat, average (6 kn) | 43d 12h |
| Displacement trawler (8 kn) | 32d 15h |
| Fast trawler (10 kn) | 26d 2h |
| Planing motor yacht (15 kn) | 17d 9h |
| Fast motor yacht (20 kn) | 13d 1h |
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 Cape Town from Antwerpen by sea?
About 6,262 nautical miles (11,597 km / 7,206 statute miles) along the practical sea route, which transits Strait of Dover. The straight-line distance is shorter, but boats follow coastlines, channels, and traffic lanes.

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.
