Voyage time by boat speed
Time underway is distance divided by speed. These are continuous-passage figures with no stops or weather margin.

|---|---|
| Sailboat, conservative (5 kn) | 47d 21h |
| Sailboat, average (6 kn) | 39d 22h |
| Displacement trawler (8 kn) | 29d 22h |
| Fast trawler (10 kn) | 23d 23h |
| Planing motor yacht (15 kn) | 15d 23h |
| Fast motor yacht (20 kn) | 11d 23h |
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 Colombo from Lisboa by sea?
About 5,745 nautical miles (10,640 km / 6,612 statute miles) along the practical sea route, which transits Strait of Gibraltar and Suez Canal and Bab-el-Mandeb. The straight-line distance is shorter, but boats follow coastlines, channels, and traffic lanes.
How long does it take to sail from Lisboa to Colombo?
At a typical sailing average of 6 knots it is about 39d 22h underway. A 10-knot trawler needs about 23d 23h, and a 20-knot motor yacht about 11d 23h. 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.
