HMS Sparrowhawk was a Vigilant-class second-class despatch/gunvessel launched on 9 February 1856 at Limehouse, England and served at various stations in the Far East. By the spring of 1865, her rig was a converted to that of a three-masted barque. She was sold in 1872 and was eventually lost in a typhoon.

Design

Her class were designed as second-class despatch and gunvessels. They were intended to operate close inshore during the Crimean War and were essentially enlarged versions of the Arrow-class gunvessel, which has been designed by the Surveyor’s Department in 1854.^[2]

Propulsion

A two-cylinder horizontal single expansion steam engine by Humphrys, Tennant and Dykes provided {{convert|726|ihp|kW|lk=in}} through a single screw,^[2] and gave a top speed of about 11 knots.^[1]

Sail plan

All Vigilant-class gunvessels were barque-rigged.^[2]

Armament

Although designed with a pair of 68-pounder Lancaster muzzle-loading rifles, the Vigilant class were finished with one {{convert|7|in|mm|adj=on}}/{{convert|110|lb|kg|adj=on}} Armstrong breech-loading gun, one {{convert|68|lb|kg|adj=on}} Lancaster muzzle-loading rifled gun and two 20-pounder breech loaders.^[2]

Service history

Porcher Island, near Prince Rupert, British Columbia, is named after Edwin Augustus Porcher (1821–1878), who served as captain of HMS Sparrowhawk at Esquimalt Naval Base, Vancouver Island, from the spring of 1865 until he returned to England in autumn 1868. While serving with the North Pacific Squadron, Commander Porcher made four summertime voyages to the North Coast of British Columbia; in 1866, 1867 and twice in 1868.
