Princess May was a steamship built in 1888 which was operated under a number of different names and owners. The ship is best known for having been involved in a grounding in 1910 which left the ship jutting completely out of the water, which became the subject of a famous shipwreck photograph. Nomenclature This ship, although it served under other names, is best known as the Princess May. The Canadian Pacific had a fleet of ocean-going ships with names beginning with “Empress". It was decided that the planned fleet of coastal liners (which in 1901 did not yet exist) would have names beginning with “Princess.” Princess May was named after Mary of Teck, who was known as “May”.

Hawthorn Leslie built another ship, the Smith, at the same time for the Formosa Trading Company. Cass was long, beam, depth of hold, 1717 gross and 1394 registered tons. Power was supplied by two triple-expansion engines, each one driving a separate propeller. Each engine had three cylinders, which, ranging from high pressure to low pressure, were 19, 30, and in diameter. The stroke on all cylinders was . Steam was generated by three coal-fired boilers. The ship was built with electric lighting installed by Rankin Kennedy of the Woodside Electrical Works, a Glasgow firm. China service Cass served in the China coast trade from 1888 to 1901 under a number of different owners and names, including Arthur, Cass (again), Ningchow, and Hating, the ship's name in 1901. During the ship's service on the China coast there was a mutiny on board and the ship was attacked by pirates. The arrival of Cass and Smith at Taiwan was called the “shipping event of the year” for the China coast. The Formosa Trading Company had been organized by the modernizing governor of Taiwan, Liu Mingchuan, based on the advice of a former manager of the China Merchant Steam Navigation Company. A contemporary source states that the ostensible purpose of ordering the two steamers was modernization of Taiwan, but the actual goal was to compete with the China Merchant Steam Navigation Company and its two
