HMS Serapis (1866)

HMS Serapis was a Euphrates-class troopship commissioned for the transport of troops to and from India. She was launched in the Thames on 26 September 1866 from the Thames Ironworks and Shipbuilding Company at Leamouth, London and was the third Royal Navy ship to bear the name. She was sold in 1894.

Design
Serapis was one of five iron-hulled vessels of the Euphrates class. All five were built to a design of 360 ft overall length by about 49 ft breadth, although Malabar was very slightly smaller than the rest of the class. They had a single screw, a speed of 14 knots, one funnel, a barque-rig sail plan, three 4-pounder guns and a white-painted hull. Her bow was a "ram bow" which projected forward below the waterline.

Career
She spent all of her career on the United Kingdom to India route carrying troops, a trip that averaged 70 days. She was the only one of her class to have been completed with a compound-expansion steam engine at build, and was the first of her class to be re-engined. While her sisters replaced their single-expansion engines with compound-expansion engines, she had the opposite adaption; her 4-cylinder horizontal compound-expansion steam engine was replaced in 1869 with a 2-cylinder single-expansion steam engine. The indicated power remained almost the same, and her top speed was largely unaffected, remaining at about 14 kn.

In September 1875 she transported the Prince of Wales to India to celebrate Queen Victoria's appointment as Empress of India. In 1884 the commanding officer, Captain Arthur Dupuis, was suspended after the ship grounded off Portland. In April 1886 she became part of the Indian training squadron.

Fate
She was sold to I Cohen on 23 November 1894 along with her sister ship Euphrates.
