 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, leading to the construction of two identical vessels for the Indian Marine.

Armament

As built, they were armed with one 8 inches (203.2 mm) 68-pounder (87cwt) muzzle-loading smoothbore gun and two 24-pounder howitzers. By 1863 the three surviving vessels of the class were armed with one 110-pounder Armstrong breech-loading gun and one 40-pounder Armstrong breech-loading gun

.

Propulsion

The class were each 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. These engines developed 80 nominal horsepower (a designed indicated horsepower of 294 ihp). The design speed under steam was 9 knots (17.6 km/h).

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 barquentine
