The Doterel class was a Royal Navy class of screw-driven sloops. They were of composite construction, with wooden hulls over an iron frame. They were a revised version of an 1874 design by the Royal Navy's Chief Constructor, William Henry White, the Osprey-class sloop. Two of the class were lost, one to an explosion off Chile and one wrecked off Canada. Gannet is preserved at Chatham Historic Dockyard.
Design[edit]
The Nathaniel Barnaby design was a development of William Henry White's 1874 Osprey-class sloop. The graceful clipper bow of the Opsreys was replaced by a vertical stem and the engines were more powerful. They were of composite construction, with wooden hulls over an iron frame.
Propulsion[edit]
Power was provided by three cylindrical boilers, which supplied steam at 60 pounds per square inch (410 kPa) to a two-cylinder horizontal compound-expansion steam engine driving a single 13-foot-1-inch (3.99 m) screw. This arrangement produced 900 to 1,128 indicated horsepower (671 to 841 kW) and a top speed of between 11 and 11.6 knots (20.4 and 21.5 km/h).[1]
Armament[edit]
They were armed with two 7-inch (90cwt) muzzle-loading rifled guns on pivoting mounts, and four 64-pounder muzzle-loading rifled guns (two on pivoting mounts, and two broadside). Four machine guns and one light gun completed the weaponry.[1]
Sail plan[edit]
All the ships of the class were provided with a barque rig,[1] that is, square-rigged foremast and mainmast, and fore-and aft sails only on the mizzen mast.
Crew[edit]
They had a complement of approximately 140 men.[1]
