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.
