The sea route from Houston (United States) to Le Havre (France) is about 4,859 nautical miles, which is 8,999 km or 5,592 statute miles. That is about 14% longer than the direct great-circle line, because the practical route follows coastlines and shipping lanes.
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 12h |
| Sailboat, average (6 kn) | 33d 18h |
| Displacement trawler (8 kn) | 25d 7h |
| Fast trawler (10 kn) | 20d 6h |
| Planing motor yacht (15 kn) | 13d 12h |
| Fast motor yacht (20 kn) | 10d 3h |
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.

Plan this passage properly
Open Houston to Le Havre in the Marine OS route planner: it suggests the sea route, then you drag waypoints, set your speed and fuel burn, and check weather and tides along the way.

How far is Le Havre from Houston by sea?
About 4,859 nautical miles (8,999 km / 5,592 statute miles) along the practical sea route. 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 33d 18h underway. A 10-knot trawler needs about 20d 6h, and a 20-knot motor yacht about 10d 3h. 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.
