A comprehensive academic study by J. R. Dickinson examining the maritime commerce of the Isle of Man across nearly two centuries, from early primary product exports (cattle, hides, fish, grain) through the rise of the illicit smuggling trade in the 17th-18th centuries. The paper analyses waterbailiff's customs accounts and port books to document how the island's strategic Irish Sea location enabled it to become a major entrepôt for contraband goods, particularly after increased English tariffs in the late 17th century, culminating in the Crown's purchase of lordship rights in 1765.
