 During the 1870s the distinction grew between ' first @-@ class ironclads ' or ' battleships ' on the one hand , and ' cruising ironclads ' designed for long @-@ range work on the other . The demands on first @-@ class ironclads for very heavy armor and armament meant increasing displacement , which reduced speed under sail ; and the fashion for turrets and barbettes made a sailing rig increasingly <unk> . HMS <unk> , launched in 1876 but not commissioned until 1881 , was the last British battleship to carry masts , and these were widely seen as a mistake . The start of the 1880s saw the end of sailing rig on ironclad battleships .
