The year of 1766 saw 118 vessels, measuring 75 tons each on the average, clear from Nantucket alone. They brought home 11,969 barrels of valued at $129,983. In 1770 the Nantucket fleet numbered 125 ships of the average size of 93 tons. During that year they took 14,331 barrels of oil worth $358,200. The ship owners of other ports, seeing Nantucket's prosperity, had tried to share in it. Their success was fairly good, but Nantucket owned at this time as many whale-ships as all the other ports of America combined."
