One of the earliest steam tow boats built in the United States for coastwise towing, the "R. B. Forbes" was built in Boston by Otis Tufts for the Boston Board of Marine Underwriters, at the behest of Robert Bennet Forbes, for whom the vessel was named. The first iron-hull vessel built in Boston, she measured 320 tons. Her two Ericson screw propellers were driven by a pair of condensing engines, each with a bore of 36 inches and a 32-inch stroke. (1)

A pioneer in coastwise towing, the "R. B. Forbes" was mainly used to tow newly-built sailing ships from New England shipyards to New York, where their owners would complete the fitting-out process and send them to sea. Unable to use her profitably to this end, the owners sold her, as did her subsequent owners. She was sold to the U.S. Navy in 1861, soon after the outbreak of the Civil War. She was lost when she went aground on the coast of North Carolina, near the Hatteras Inlet on February 25, 1862, a total loss. (2)

"Engine-powered vessel" is a collective term used by nautical historians to include all vessel types using engine power of any type for propulsion, whether assisted by sails, oars, or other motive power. In Lane's time, steam reciprocating engines fueled by wood or coal were the only practical source of this power for ships using paddle-wheels or screw propellers to convert heat energy into motion.

For most of the nineteenth century, steamships had sails for auxiliary power; indeed the earliest examples relied principally on sails, using engine power in calm weather to shorten the voyage time or keep to a schedule. As engines became more efficient, powerful, and reliable, sail plans were reduced, to be used only to steady a vessel's motion in a seaway (for the sake of seasick passengers), or to maintain headway if the engine broke down. Only harbor craft, ferry boats, and coastwise passenger steamers relied solely on engine power.

Among Lane's depictions of steamships, the auxiliary steam packet Auxiliary Steam Packet Ship Massachusetts (inv. 442) is a good example of primary reliance on sails, while the steam demi-bark The "Britannia" Entering Boston Harbor, 1848 (inv. 49) and the Cunard Liner "Britannia", 1842 (inv. 259) have relegated sails to secondary (or simply emergency) motive power.

Tug boat is a general term for vessels of a variety of sizes designed to tow and push large vessels into and out of harbor berths, through confined waterways, and undertake towing and salvage work in deep water. Tugs designed for towing large vessels over long ocean routes are called tow boats, and are larger and more powerful than their harbor-based counterparts.

Throughout the nineteenth century, tug boats were powered with a variety of steam reciprocating engines, the "cross-head" and "walking beam" types being suitable for the early vessels driven by paddle wheels and used in protected harbors. The introduction of the screw propeller and more compact compound engines, made tug boats less susceptible to damage when used in open ocean, leading to the development of tow boats. (1)

New York Harbor was the first American seaport to make extensive use of harbor tugs, due to the size of New York Bay and anchorages therein. A multitude of wharves along the shorelines of Manhattan, Brooklyn, and the New Jersey side (not to mention river traffic from points north on the Hudson River and barge traffic from the Delaware and Hudson Canal) all contributed to a demand for their services. (2)

Boston Harbor, by contrast, was much smaller, with its wharves confined to a compact waterfront. Here, it was easier to move a vessel by warping it from pierhead to pierhead than to use a tug boat for such short-distance work. Even with expansion of the waterfront in the late nineteenth century, Boston had a far smaller harbor tug fleet than New York. (3)

What Boston did need were a few large tow boats for coastwise work. Most large shipyards north of Cape Cod needed tow boat services for sending the ships they built to southern ports for fitting-out. New York had a particular need for this service so vessels built in other yards (including Boston's) could be towed to it for completion (including sails, boats, cabin finish work, marine hardware, and sometimes even masts and rigging). Boston's proximity to New England shipyards made it the logical place to operate a towing service, and Robert Bennet Forbes was one of the first to act on this opportunity. An iron-hull, screw-propelled tow boat was built to his specifications in 1846 for Boston underwriters, who named it in his honor. (4)

Robert Bennet Forbes (1804–89) of Boston was a key figure in his family's business in the China trade. While his brothers and cousins took positions as land-based merchants stationed either in Boston or Canton, Robert Bennet Forbes chose life at sea. He went on many trips to China, starting in 1817 as a cabin boy—thirteen years old—and eventually as a ship captain.

Forbes became a partner in the firm in 1832, known by then as Russell & Co., Canton, and went for a two-year trip to China in 1838–40 as a merchant. He was a proponent of steam power, which helped ships on the long voyage to China and Japan, and gave them the speed to evade the pirates who were ever present in the opium trade. His firm built about 70 ships, of which he was owner or part owner of several.

Robert Bennet Forbes also helped to introduce yachting as a sport, and participated in some of the first yacht races. His book Personal Reminiscences, published in 1892, lists many of these exploits, as well as all of the vessels he owned and built.

Forbes was known for his adventurous spirit. In 1846, when news of the Irish famine reached Boston, he convinced the U.S.Navy to lend him the "USS Jamestown" to take food to famine sufferers in 1847. He was the first civilian given the honor of commanding a naval vessel, and he crossed the Atlantic in a record seventeen days. Forbes wrote a book about his trans-Atlantic voyage for which he commissioned Lane to make the frontispiece illustration.

The "Jamestown" commission was one of several works Lane made for Forbes. Forbes was not only adventurous but innovative, and he commissioned Lane to make works after two of his newly designed steam vessels: the "Massachusetts," a packet ship that used steam power to supplement wind power, and the "Antelope," that relied primarily on steam power.

The Forbes family lived in Milton, Massachusetts, and also had a home in Beverly, Massachusetts. In 1856 Forbes bought land in West Manchester and built a summer home there which he christened "Masconomo" after the sagamore, chief of the Agawam.

In 1834 Captain Forbes married Rose Greene Smith. She died September 18, 1885, having borne her husband three children: Robert Bennet Forbes (1837–June 30, 1891); Edith Forbes, who married Charles Eliot Perkins; and James Murray Forbes (b. July 17, 1845). He died on November 23, 1889 in Milton.
