I wouldn’t know, but looking at https://en.wikipedia.org/wiki/Trade_winds, that should be an option. It may be unpopular because of logistic and security concerns, though (the Canary Islands are regular departure points, but that may be cheating for this record)

The (I am sure) bestselling book “How To Row An Ocean” (http://thenextchallenge.org/books/row-ocean/) probably has an answer.
