Although many Whaling ships plied their trade under sail, and improvements had been made, the technology the small boats that they lowered to pursue available to whalers in the middle of the 19th whales were also powered by wind, or by the century severely limited the number of brute strength of their crew’s arms at the oars. animals that could be taken and processed in The killing of whales required men to bring a working day. Furthermore, as Melville their frail craft alongside the huge quarry, noted it largely precluded exploitation of the faster species.

By far the most whaling industry by providing a much more significant development in this regard was the efficient means to despatch whales, both discovery of the vast stocks of whales in the quickly and from a distance.
