How long does it take a boat to go from the US to Britain?

Answer 1

The westerly winds make this somewhat faster than from the UK to the US.

It depends on the type of boat or ship. The ancient sailing ships took between three weeks and three months depending on the prevailing winds, and a lower range of about two weeks would apply to sailboats using the most direct routes.

In the 19th century, steamships cut the time to less than two weeks. Modern cruise ships, cargo ships, tankers, and container ships can transit the Atlantic in as little as 6 or 7 days, averaging 20 to 25 knots. But slower ships can still take 2 or 3 weeks to reach various destinations in Europe.
