How long does it take to sail a 43 foot sloop to europe from the east coast?

Question

a ball park is fine

Answer 1

With favorable winds, three weeks should do it.  Assume that you can make six knots, and measure the distance.

Answer 2

1: when are you planning the trip

2: where in Europe are you heading

myself i would plan on a 3/4 week crossing but provision for 5 its normally a 14/18 day trip for a 30/40 mtr sloop (that's from the Canaries)
