Voyage time by boat speed

Time underway is distance divided by speed. These are continuous-passage figures with no stops or weather margin.

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.

Frequently asked questions

How far is New York from Boston by sea?

About 215 nautical miles (397 km / 247 statute miles) along the practical sea route. The straight-line distance is shorter, but boats follow coastlines, channels, and traffic lanes.

How long does it take to sail from Boston to New York?

At a typical sailing average of 6 knots it is about 1d 12h underway. A 10-knot trawler needs about 22h, and a 20-knot motor yacht about 11h. 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.
