What businesses emerged as a part of the whaling industry?

The whaling industry was responsible for a number of supporting businesses including: shipbuilders, cooper smiths, sail makers, caulkers, and suppliers. These businesses sprung up at ocean ports that developed into robust whaling centers: places like Nantucket, New Bedford, New London, Mystic, Sag Harbor, Providence, and Cold Spring Harbor became major whaling centers. The authors present the history of whaling out of two major ports: Nantucket, a small island near Cape Cod, and New Bedford.
