Built of a traditional wooden construction, the Racer class were a lengthened version of the Swallow-class sloop,[Note 1] which in turn had been intended as "type of screw vessel below the Cruizer". The extra length gave greater speed, and combined with a considerable increase in power, this gave a speed of about 10 knots (19 km/h; 12 mph), rather more than the 7 knots (13 km/h; 8.1 mph) of the previous class.[1]
The class were armed with a single 32-pounder (58 cwt) gun on a pivot mount and ten 32-pounder (25 cwt) carronades on the broadside. These guns were all smoothbore muzzle-loading, and were little changed from the standard guns of Nelson's era.[2]
Propulsion was provided by a James Watt & Co two-cylinder horizontal single-expansion steam engine developing 461 indicated horsepower (344 kW) and driving a single screw. At maximum power under steam, her top speed was about 9.9 knots (18.3 km/h; 11.4 mph). A barque rig of sails was carried, which meant she had three masts with a square rig on the fore and main masts.[1]
Construction
Cordelia was laid down at Pembroke Dockyard in October 1855 and launched on 3 July 1856.[2] The total cost was £33,428, of which the machinery cost £9,014.[1]
Royal Navy service
She was commissioned on 11 April 1857 under Commander Charles Egerton Harcourt-Vernon and initially sent to the East Indies Station until being assigned to the Australia Station in 1859. In 1860 she served in the First Taranaki War.[2] Command passed in June 1861 to Commander Francis Alexander Hume; on returning to the UK, she was paid off at Plymouth on 2 April 1862.[3]
She was recommissioned on 24 June 1864 under Commander John Binney Scott and then served in the North American and West Indies Station until she was paid off on 9 July 1868 at Plymouth; meanwhile Commander Thomas Alexis De Wahl had been given command on 3 March 1865 when Scott became invalided, and was in turn succeeded on 16 September 1867 by Commander Charles Parry.[3]
Fate
She was sold on 12 May 1870 for breaking up at Plymouth.[1]
Notes
^Cordelia and Gannet were ordered as Swallow-class ships but the design was changed before construction.
