RMS Unicorn was a British transatlantic paddle steamer built in 1836. After being bought in 1840, she was the first ship to sail with Cunard, traveling between the United Kingdom and Canada. She left the company in 1846, and would continue to operate under various owners until 1872, when her register was closed.

Description

The Unicorn a wooden hulled express ship which measured 650 gross register tons, and was 390 net register tons. She had a beam of 23.5 feet (7.16 metres) and a depth of 17.3 feet (5.27 metres). She had accommodations for 51 cabin class passengers and 190 steerage passengers.^[1] She was originally built with two flue boilers, but had these replaced with two tubular boilers in 1848. These new boilers were 10ft (3m) long and wide, though were 14ft (4.27m) tall and had three furnaces each. She had an average speed of 9.5 knots ^[2]

Career

Unicorn was built by Robert Steele & Company in Greenock and launched in May 1836.^[1] She had two sister ships: Eagle and City of Glasgow.^[3] Unicorn, along with her sisters, originally served under George & John Burns (Glasgow & Liverpool Steam Shipping Co.), sailing the Glasgow-Liverpool route.^[1][3] In 1840, she was purchased by Samuel Cunard for the newly formed Cunard Line, becoming the first ship to sail with the company. She departed on her maiden voyage on May 16th 1840 with 453 tons of coal, 27 passengers and 80 crew. She arrived at Halifax on June 1st, and Boston on the 3rd. ^{[4][5][6] [7]}After entering service with Cunard, Unicorn initially sailed along the Halifax-Pictou-Quebec route before switching to Liverpool-Halifax-Boston route. On November 11th 1843, she was involved in rescuing passengers and crew from Premier, a brig that was wrecked in the St. Lawrence.^[3] In 1845, she was sold away to James Whitney, and received a major refit on the River Clyde.^[1]

After leaving Cunard in 1845, she briefly served as a corvette in the Portuguese Navy.^[3] She was bought by Samuel Cunard in January 1849, given to his son in February, and sold in October 1849. From 1849 to 1853, she operated under the Pacific Mail Steamship Co. and would make trips from San Francisco to Panama.^[1][3] After that, she was put up for sale in Australia before going on to operate in Chinese waters.^[1] In 1857, she was renamed E. H. Green.^[1] Information is scarce after 1859, although her register was closed on May 16 1872, meaning she was likely sold for scrap not long prior. ^[8]
