How long did it take a ship to sail from Japan to America (north carolina area) back in the 1700's?

Answer 1

the trip is about 20,000 miles each way....the route for a sailing ship would be out of Japan and south past the Philippines, pick up the winter N'orEast Monsoon across the Indian Ocean then south about Africa, up the Atlantic using the Trade Winds....in the 1700's, first of all, very few if any ships were doing this trip ( Japan had minimum contact with the West till 1856); ocean going sail in the 1700's weren't anything like the clippers of the 1840s, so at a guess I would think they averaged 6 knots.......20,000 divided by 8 is ( raise your hands if you know) 138 plus days for an exceptionally fast trip...200 would be more like it.
