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 Honolulu from Santos by sea?

About 8,502 nautical miles (15,747 km / 9,784 statute miles) along the practical sea route, which transits Strait of Magellan. The straight-line distance is shorter, but boats follow coastlines, channels, and traffic lanes.

How long does it take to sail from Santos to Honolulu?

At a typical sailing average of 6 knots it is about 59d 1h underway. A 10-knot trawler needs about 35d 10h, and a 20-knot motor yacht about 17d 17h. 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.
