His business grew. He eventually had to design a new type of boat to navigate the narrow river, filled with obstacles that would sink most rear-paddle boats. Hubbard Hart invented the first inboard-paddle boat in 1866, launching the
Griffin. This new design of boat was featured in the 1892
Chicago World's Fair. In the following three years, Hart Lines also added the
Ocklawaha and
Pansoffkee to the fleet. The
James Burt had been sunk in the Civil War, and the
Silver Springs was decommissioned with the new boats. While the new boats were described as ugly, trips on them received nothing but positive reviews.
Harriet Beecher Stowe, who was first afraid to board the boats, wrote nothing but praise for the Hart Line. Attractions along the way included touring Hart’s world famous orange groves (which even allowed guests to pick some fruit), shooting wildlife (including
alligators), admiring the rustic Florida beauty, and swimming in Silver Springs. The Hart Line's success continued until a gradual downturn in business began in 1889.
Freight business had been absorbed by
railroads, leaving the competing steamboat lines dependent on tourists for revenue. Nevertheless, through hard work and dedication, Hart managed to keep the fleet running. His strategies included building luxury hotels along the way, renovating the boats to have bigger cabins, and offering cruises down different rivers, including the
Indian River in 1883. He suffered a setback when his hotel, the Putnam House, burned down in the Palatka Fire of 1884, after being open only a short time. In 1895, Hubbard Hart died as a result of a fall from a
trolley car in
Atlanta, Georgia, where he was attending a business meeting. Hart Lines was taken over by his brother-in-law and remained operating into the 1920s, when automobile travel rendered it obsolete. ==References==
