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 Shanghai from Ho Chi Minh City by sea?

About 1,725 nautical miles (3,195 km / 1,985 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 Ho Chi Minh City to Shanghai?

At a typical sailing average of 6 knots it is about 12d 0h underway. A 10-knot trawler needs about 7d 5h, and a 20-knot motor yacht about 3d 14h. 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.
