The sea route from Boston (United States) to New York (United States) is about 215 nautical miles, which is 397 km or 247 statute miles. That is about 30% 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) | 1d 19h |
| Sailboat, average (6 kn) | 1d 12h |
| Displacement trawler (8 kn) | 1d 3h |
| Fast trawler (10 kn) | 22h |
| Planing motor yacht (15 kn) | 14h |
| Fast motor yacht (20 kn) | 11h |
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 Boston to New York 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 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.
