in 1776 how long did it take a ship to get from france to america?

It's 3,567 miles between France's port of Calais and New York.

Depending upon the wind, sailing ships averaged any where between 90 and 150 miles per day.

If a ship averaged 120 miles a day, we can find the time by dividing 3,567 by 120. So -- typically, a ship traveling between these two countries would take about a month to make the journey.
