The Gulf Stream Chart.
Franklin was interested in the North Atlantic Ocean circulation patterns. While in England in 1768 he heard a complaint from the Colonial Board of Customs: Why did it take British packet ships carrying mail several weeks longer to reach New York than it took an average merchant ship to reach Newport, Rhode Island - despite the merchantmen having a longer and more complex voyage because they left from London, while the packets left from Falmouth in Cornwall?
Franklin put the question to his cousin Timothy Folger, a Nantucket whaler captain, who told him that merchant ships routinely avoided a strong eastbound mid-ocean current while the mail packet captains sailed dead into it, thus fighting an adverse current of 3 miles per hour (5 km/h). Franklin worked with Folger and other experienced ship captains, learning enough to chart the current and name it the Gulf Stream, by which it is still known today.
It took many years for British sea captains finally to adopt Franklin's advice on navigating the current; once they did, they were able to trim two weeks from their sailing time.
