“For purposes of comparison in pitching and lifting, etc., the
_Sultan_ had the height of the _Devastation’s_ upper deck at side
painted on her in a broad white stripe, so that the behaviour of
the two ships might be quickly appreciated apart from the records
of instruments. The lowness of the extremities of the _Devastation_
gives a great deal of interest to the pitching and lifting (really
the longitudinal rolling) of the vessel. Two trials were made, one on
the 9th and the other on the 15th of September. On the first of these
occasions, she was accompanied by the _Sultan_ only, and on the second
she was accompanied by the _Agincourt_ only. The seas met with on the
9th of September were lumpy and irregular, the wind having shifted
somewhat suddenly during the previous night. Having got well out to
sea, about forty miles off land, the wind was found to be blowing
rather north of west with a force of a moderate gale, its speed
varying from forty to forty-five miles per hour; and the largest of
the waves were found to vary from 300 to 350 feet in length from crest
to crest, occasionally reaching 400 feet--the greatest heights from
hollow to crest being 15 and 16 feet. Going head to sea, at from six
to seven knots, both vessels pitched considerably; the _Devastation_,
however, had the best of it, pitching through smaller angles than
the _Sultan_. The latter vessel was remarkably lively; at one moment
she was to be seen with her fore-foot completely out of water, and
the next with her bow dipped down to so great an extent that it was
difficult to see from the flying deck of the _Devastation_--although
the ships were pretty close together--whether the sea did not really
break inboard; and this notwithstanding that the bow of the _Sultan_
rises forward some 30 feet above the surface of the water. On the
other hand, the forecastle deck of the _Devastation_ was repeatedly
swept by the seas, to each of which she rose with surprising
readiness; indeed, it invariably happened that the seas broke upon her
during the upward journey of the bow, and there is no doubt it is to
this fact that her moderate pitching was mainly due, as the weight of
the water on the forecastle-deck during the short period it remained
there acted as a retarding force, preventing the bow from lifting
as high as it otherwise would, and this, of course, limited the
succeeding pitch, and so on. The maximum angle pitched through on this
occasion, i.e. the angle between the extreme elevation and depression
of the bow, was 7½ degrees. Each vessel behaved extremely well when
placed broadside on to the sea, rolling very little. The trial of the
ship on the 15th of September, in company with the _Agincourt_, was
by far the most severe of any. Early in the morning the vessel got
under weigh and steamed out to sea, accompanied by the _Agincourt_.
The wind was blowing with considerable force from the north-west,
