Packet boats were medium-sized boats designed for domestic mail, passenger, and freight transportation in European countries and their colonies, including North American rivers and canals. They were used extensively during the 18th and 19th centuries and featured regularly scheduled service.
Packet craft were used extensively in European coastal mail services since the 17th century, and gradually added cramped passenger accommodation. As early as 1629, the Dutch East India Company was carrying some passengers on the ill-fated Batavia from Texel in Holland to Java. Later, scheduled services were offered, but the time journeys took depended much on the weather. They are even found to be a subject of Daniel Defoe's 1724 novel Roxana: The Fortunate Mistress. In England the King maintained a weekly packet service with the continent and Ireland using 15 packet vessels. Their importance was evident in the Rose Hill Packet becoming the first craft built in the colony of New South Wales in 1789. In North America, when the Erie Canal opened in New York state in 1825 along the Mohawk River, demand quickly rose for travelers to be accommodated.
Over the two centuries of the sailing packet craft development, they came in various rig configurations which included: schooners, schooners-brigs, sloops, cutters, brigs, brigantines, luggers, feluccas, galleys, xebecs, barques and their ultimate development in the clipper ships. Earlier they were also known as dispatch boats, but the service was also provided by privateers during time of war, and on occasion chartered private yachts. News of "record passages" was eagerly awaited by the public, and the craft's captain and crew were often celebrated in the press. Behind this search for sailing faster than the wind however lay the foundations for a development in naval architecture and its science which would serve until the appearance of the steam vessels.
The American canal packet boats were typically narrow (about 14 feet) to accommodate canals, but might be 70-90 feet long. In the cabin space they could carry up to 60 passengers. Unlike European and American sailing vessels, that sought to attain greater speed under sail, the canal packet boats were drawn through the Erie Canal by teams of two or three horses or mules. Compared to overland travel, the boats cut journey time in half and were much more comfortable. Travelers could get from New York City to Buffalo in ten days, with a combination of sailing and packet boats. Some passengers took the boats to see both the Erie Canal and the natural landscapes. Significantly, thousands of others used packet boats to emigrate to Ohio and other parts of the Midwest. These boats were also instrumental in the settling of and travel within Upstate New York through the branch canals such as the Chenango Canal. Packet boats were also popular along the James River and Kanawha Canal in Virginia, allowing travel beyond the falls upriver.
Mail steamers were steamships which carried the mail across waterways, such as across an ocean or between islands, primarily during the 19th century and early 20th century, when the cost of sending a letter was declining to the point an ordinary person could afford the cost of sending a letter across great distances. In addition to carrying mail, most mail steamers carried passengers or cargo since the revenue from the mail service, if any, was insufficient by itself to pay for the cost of its travel.
However, the advantage for a steamship carrying mail was that its arrival would be advertised in advance in the newspapers, thus giving it "free advertising" as a travel option for passengers or cargo. In most cases, mail carried by mail steamers was delivered to the post office to which it was addressed. In some cases, the incoming mail would be advertised in the local newspaper for pickup at the post office or at the steamship's office for a fee, if not already fee-paid.
Occasionally, because of political instability when a post office could not provide normal services, incoming mail from a mail steamer would be delivered to a local delivery service, which would deliver the mail and charge the addressee an extra fee for the service. When this occurred, the local delivery service would place its own local service stamp or mark on the envelope when the extra fee was paid.
Mail carried by these steamers - sometimes known as paquebot mail - was subject to various regulations by the governments involved as well as the Universal Postal Union's (UPU) regulations stated at the UPU Vienna Conference of 1891.
The C-82 Packet twin-engined, twin-boom cargo aircraft designed and built by Fairchild Aircraft was named as a tribute to the packet boat. It was used by the United States Army Air Forces and the successor United States Air Force following World War II.
