But, prior to the precise dimensions being fixed for the second order, I with confidence proposed my theory of the greater carrying power and accommodation, both for cargo and passengers, that would be gained by constructing the new vessels of increased length, without any increase of beam.

I conceived that they would show improved qualities in a sea-way, and that, notwithstanding the increased accommodation, the same speed with the same power would be obtained, by only a slight increase in the first cost.

The result was, that I was allowed to settle the dimensions; and the following were then decided on: Length, 310 feet; beam, 34 feet; depth of hold, 24 feet 9 inches; all of which were fully compensated for by making the upper deck entirely of iron.

In this way, the hull of the ship was converted into a box girder of immensely increased strength, and was, I believe, the first ocean steamer ever so constructed.

The rig too was unique.
