Sea distance from Houston to Hamburg
The sea route from Houston (United States) to Hamburg (Germany) is about 5,304 nautical miles, which is 9,824 km or 6,104 statute miles. The route transits Kiel Canal. That is about 18% 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) | 44d 5h |
| Sailboat, average (6 kn) | 36d 20h |
| Displacement trawler (8 kn) | 27d 15h |
| Fast trawler (10 kn) | 22d 2h |
| Planing motor yacht (15 kn) | 14d 18h |
| Fast motor yacht (20 kn) | 11d 1h |
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 Hamburg 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 Hamburg from Houston by sea?
About 5,304 nautical miles (9,824 km / 6,104 statute miles) along the practical sea route, which transits Kiel Canal. The straight-line distance is shorter, but boats follow coastlines, channels, and traffic lanes.
How long does it take to sail from Houston to Hamburg?
At a typical sailing average of 6 knots it is about 36d 20h underway. A 10-knot trawler needs about 22d 2h, and a 20-knot motor yacht about 11d 1h. 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.
