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) | 82d 18h |
| Sailboat, average (6 kn) | 68d 23h |
| Displacement trawler (8 kn) | 51d 18h |
| Fast trawler (10 kn) | 41d 9h |
| Planing motor yacht (15 kn) | 27d 14h |
| Fast motor yacht (20 kn) | 20d 17h |
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 Honolulu from Genova by sea?
About 9,932 nautical miles (18,394 km / 11,430 statute miles) along the practical sea route, which transits Strait of Gibraltar and Panama Canal. The straight-line distance is shorter, but boats follow coastlines, channels, and traffic lanes.
How long does it take to sail from Genova to Honolulu?
At a typical sailing average of 6 knots it is about 68d 23h underway. A 10-knot trawler needs about 41d 9h, and a 20-knot motor yacht about 20d 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.
