In 1878 "Challenger" went through an overhaul by the Chief Constructor at Chatham Dockyard with a view to converting the vessel into a training ship for boys of the Royal Navy. She was found suitable and it was planned to take the place of HMS "Eurydice" which sank off the Isle of Wight on 24 March 1878. The Admiralty did not go ahead with the conversion and she remained in reserve until 1883, when she was converted into a receiving hulk in the River Medway, where she stayed until she was sold to J B Garnham on 6 January 1921 and broken up for her copper bottom in 1921.
