The Rosario class was a class of seven screw-sloops of wooden construction built for the Royal Navy between 1860 and 1862. A further six vessels were ordered and laid down, but were cancelled in 1863 before launch. This was the last class of purely wooden sloops built for the Royal Navy.
The Rosario class were designed in 1858 by Issac Watts, the Director of Naval Construction. They were built of wood, were rated for 11 guns and were built with a full ship rig of sails (this was reduced to a barque rig by about 1869). With a length overall of 160 feet (49 m) and a beam of 30 feet 4 inches (9.25 m), they had a displacement of 913 tonnes. These were the last sloops constructed for the Royal Navy to retain all-wooden construction; their successors, the Amazon class, incorporated iron cross beams.
All the completed vessels, with the exception of Shearwater, were fitted with a Greenock Foundry Company two-cylinder horizontal single-expansion steam engine driving a single screw. With an indicated horsepower of between 436 horsepower (325 kW) and 627 horsepower (468 kW) they were capable of about 9 knots (17 km/h) under steam.Shearwater's R & W Hawthorn engine was similar in design and power.
As designed, ships of the class carried a single slide-mounted 40-pounder Armstrong breech-loading gun, six 32-pounder muzzle-loading smooth-bore guns and four pivot-mounted 20-pounder Armstrong breech loaders. By 1869 the armament had been reduced to a single 7-inch (180 mm) muzzle-loading gun and two 40-pounders.
Rosario served a four-year commission on the North America and West Indies Station and then served an eight-year commission in Australia. She paid off in Sheerness in 1875 and was broken up nearly ten years later.
Peterel served three commissions as a warship, on the North America and West Indies Station, the Cape of Good Hope Station and the Pacific Station. In 1877 she became a lightship marking the wreck of Vanguard, then in 1885 she was converted into a coal depot before finally being sold in 1901, the longest lived of her class.
