Packet shipping was conducted by vessels of many types in many regions over the last four centuries, but the packets depicted by Lane were the products of nineteenth-century mercantilism and the Industrial Revolution. The packets sailing out of Boston and New York for European ports were large vessels, invariably ship-rigged, and if not as sharp-ended as clipper ships, had sufficiently fine hull forms to make fast, if not record, passages.
A packet ship's highest priority was delivery of mail on a regular schedule. Passengers and high-value trade goods occupied the considerable remaining hold space. This was particularly true of west-bound passages, which brought fine European wares and throngs of immigrants to America. East-bound passages brought professionals, students, travelers, and high-value raw and semi-finished materials to European ports, mainly Britain and France, and to a lesser extent, the Netherlands and Germany.
East-bound cargos were dominated by southern products - baled cotton, rice, tobacco, and naval stores. These were delivered to New York and other northern ports by coastal packets (mainly brigs and small ships) for transatlantic shipment. Northern products included flaxseed, iron ore, fruit, wool, hides, and flour. Delivery times were on average well within 30 days, giving credence to the packet lines' promise of scheduled delivery.
West-bound passages, which meant sailing against the wind, took longer—34 to 40 days on average, depending on the port of departure. Cargos and passengers were a far more varied lot with little of the consistency of east-bound counterparts.
Lane's paintings depict Boston and New York packet ships in the peak years of their employment. The Civil War, coupled with the development of reliable steam engines for marine propulsion, posed challenges the sailing ship could not overcome. Coastal packet lines went quickly, the transatlantic lines lasting into the 1870s.
