One of the first sites chosen for a school ship was Liverpool, in 1857. The ship they chose to accommodate the school, to be provided by the Admiralty and moored in the Sloyne, off Rock Ferry on the River Mersey, was the corvette HMS "Conway". There were to be three "Conway"s over the years, the name being transferred to the new ship each time it was replaced. In 1861 HMS "Winchester" took the name, but the one that housed the school for most of its life was lent by the Royal Navy to the Mercantile Marine Service Association in 1875. This was the two-decker , a 92-gun second-rate line-of-battle ship. She was 205 ft (62.5 m) long on the gundeck, 54 ft (16 m) in beam, and displaced 4,375 long tons. During her operational life she was equipped with ten 8-inch (200 mm) guns and eighty-two 30-pounders. Launched in June 1839, she was entirely built from West African hardwoods and copper fastened, with copper sheathing anti-fouling to her under parts. She had survived the Baltic Blockade during the Crimean War, later protecting British possessions in the Caribbean and 'showing the flag' along the eastern seaboard of North America 50 years after the British surrender at Yorktown. In 1876 she was renamed "Conway" and moored on the Mersey.
