Rolling
In the 1860s rolling was measured as the sum of the angles to port and to starboard. "Admiral Dacres Report for 1864 shows that on the four days when all the ships were together, the means of the extreme rolls recorded were as follow: Hector, 10 degrees; Warrior and Defence, 10.25; Black Prince, 11.05; Prince Consort, 11.75; and Edgar (wooden line-of-battle ship), 14.25. The Warrior's rolling was measured by a different instrument from that used on board the other ships, so that she cannot fairly be compared with them. This record is, however, of great interest, on account of the comparison it renders possible between the behaviour of the iron-clads and the wooden two-decker, the latter proving the heaviest roller in the squadron. In Admiral Yelverton's Report for 1866, there are given examples of the comparative rolling of several of the iron-clads, obtained from three days'observations, of which the mean results are:- Achilles and Bellerophon, 6.6 degrees; Hector, 11.3; Ocean, 14.3; Lord Clyde, 16.1; Pallas, 17.3. ... The small size of the Pallas, as compared with the other ships, puts her at a great disadvantage as regards comparative rolling in ordinary waves."
"The Achilles has a distance of about 3 feet between the centre of gravity and the metacentre, and is a remarkable steady ship; whereas the Prince Consort, with a distance of 6 feet, rolls much more than the Achilles."

Famous quotes containing the word rolling:
“The gods had condemned Sisyphus to ceaselessly rolling a rock to the top of a mountain, whence the stone would fall back of its own weight. They had thought with some reason that there is no more dreadful punishment than futile and hopeless labor.”

“But dread
was in her, a bloodbeat, it was against the rolling dark
oncoming river she raised bulwarks....”
