Question

If you wanted to sail across the Pacific Ocean in a sail boat, going the fastest speed at all times, at which latitude would it be best to keep your sailboat to get the full potential of the winds?

Answer 1

Which way? If you are going east, you want to use the trade winds, so you want to be below about 30 degrees. If you are going west, you want to use the prevailing westerlies, so you want to be about 50 degrees.
