Design
Developed during the Crimean War as an enlarged version of W. H. Walker's ''Albacore'' class, the ''Algerines'' were an acknowledgement that gunboats designed for coastal operations would inevitably be called upon to act in a cruising role, both in shallow and in deeper water. Their increased size gave them much improved accommodation, and in general they were effective vessels.Armament
As built, they were armed with one 68-pounder (87cwt) muzzle-loading smoothbore gun and two 24-pounder howitzers.Propulsion
''Jaseur'' was fitted with a 2-cylinder horizontal direct-acting single-expansion steam engine manufactured by Maudslay, Sons & Field. This engine drove a single screw, which for the first time in a gunboat was provided with a hoisting mechanism; this ensured a better performance under sail than previous classes.Preston (2007) p.155 Her engine developed 80 Horsepower#Nominal horsepower, nominal horsepower (a designed Horsepower#Indicated horsepower, indicated horsepower of ). The design speed under steam was .Rig
Fitted at first with a simple schooner rig (often known as a "gunboat rig" in the Royal Navy), the use of these vessels as cruisers encouraged commanding officers on far-flung stations to augment their sail area by fitting topmasts and yards, making them barquentines.Construction
Ordered on 22 September 1856, she was laid down at Blackwall Yard#Greens, the Blackwall Yard premises of R & H Green. She was launched on 7 March 1857, and her first (and only) commanding officer, Lieutenant John Binney Scott joined on 28 July 1857. She commissioned on 5 September 1857 for the North America and West Indies station.Operational service
Service on the North America and West Indies station in the late 1850s involved deterring the slave trade on the western side of the Atlantic. Although there was considerable activity in chasing and examining potential slavers, it was rare to find a vessel engaged in the slave trade which could be legally detained. ''Jaseur'' had already boarded 3 vessels during March 1858 when the Commodore at Jamaica directed that his ships (''Styx'', ''Basilisk'', ''Jaseur'', , ''Skipjack'' and ''Forward'') were to "be kept actively employed in cruizing round Cuba for the suppression of the slave trade". She arrived in Havana in July 1858 for coal, departing the same day for Tampico. In October 1858, ''Jaseur'' and ''Kite'' assisted in the search for the American barque ''Parthian'', which was reported to be in distress off Bermuda. The President of the United States later transmitted his thanks to the officers and crews of both vessels.Fate
''Jaseur'' was lost on the Bajo Nuevo Bank 200 miles south-east of JamaicaApproximately in position on 26 February 1859 on passage from Port Royal to San Juan de NicaraguaKnown as Greytown in 1859. while under the command of Lieutenant Scott. All personnel on board were saved. Her stores were recovered in April by ''Cuba'' or ''Zelinda'', tender to , the receiving ship at Jamaica.Notes
