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) | 63d 2h |
| Sailboat, average (6 kn) | 52d 14h |
| Displacement trawler (8 kn) | 39d 11h |
| Fast trawler (10 kn) | 31d 13h |
| Planing motor yacht (15 kn) | 21d 1h |
| Fast motor yacht (20 kn) | 15d 19h |
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 Durban from Miami by sea?
About 7,572 nautical miles (14,024 km / 8,714 statute miles) along the practical sea route. The straight-line distance is shorter, but boats follow coastlines, channels, and traffic lanes.

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.
