Voyage time by boat speed
Time underway is distance divided by speed. These are continuous-passage figures with no stops or weather margin.
| Boat and speed | Time underway |
|---|---|
| Sailboat, conservative (5 kn) | 77d 16h |
| Sailboat, average (6 kn) | 64d 17h |
| Displacement trawler (8 kn) | 48d 13h |
| Fast trawler (10 kn) | 38d 20h |
| Planing motor yacht (15 kn) | 25d 21h |
| Fast motor yacht (20 kn) | 19d 10h |
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 Miami by sea?
About 9,319 nautical miles (17,260 km / 10,725 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.

At a typical sailing average of 6 knots it is about 64d 17h underway. A 10-knot trawler needs about 38d 20h, and a 20-knot motor yacht about 19d 10h. 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.
