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) | 40d 10h |
| Sailboat, average (6 kn) | 33d 16h |
| Displacement trawler (8 kn) | 25d 6h |
| Fast trawler (10 kn) | 20d 5h |
| Planing motor yacht (15 kn) | 13d 11h |
| Fast motor yacht (20 kn) | 10d 2h |
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 Jeddah from Cape Town by sea?
About 4,849 nautical miles (8,981 km / 5,580 statute miles) along the practical sea route, which transits 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 Cape Town to Jeddah?
At a typical sailing average of 6 knots it is about 33d 16h underway. A 10-knot trawler needs about 20d 5h, and a 20-knot motor yacht about 10d 2h. 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.
