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.

Building with these numbers? The sea route & distance API returns this figure, voyage time, and route geometry for any port pair in one GET request.

Frequently asked questions

How far is Ho Chi Minh City from Cape Town by sea?

About 6,388 nautical miles (11,831 km / 7,352 statute miles) along the practical sea route, which transits Sunda Strait. The straight-line distance is shorter, but boats follow coastlines, channels, and traffic lanes.

How long does it take to sail from Cape Town to Ho Chi Minh City?

At a typical sailing average of 6 knots it is about 44d 9h underway. A 10-knot trawler needs about 26d 15h, and a 20-knot motor yacht about 13d 7h. 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.
