It will therefore be seen that, by adopting in the new design the proportions and form 
of fig. 2, a ship of the required scantlings and speed will be obtained on a length of 342 
feet, and a breadth of 68-| feet ; whereas if the proportions and form of fig. 1 are adopted, 
the ship, although of the same scantlings and speed only, will require to be 581 feet long 
and 83 feet broad, the steam-power being in both cases as nearly as possible the same. 
It was by considerations of the above nature, worked out more fully and corrected by 
the results of the trials of many large ships of Avar, that in designing the ‘ Bellerophon’ I 
Ayas led to depart so considerably from the proportions and form of the ‘ Warrior,’ 4 Mino- 
taur,’ and other long iron-clads. 
We are now in possession of the actual performances of these ships, and it is upon 
these as a basis that I propose to continue the present investigation. 
From the drawings of the ‘ Minotaur’ and of the ‘Bellerophon,’ and from calculations 
based upon them, also from the official reports of the measured mile trials made with 
those ships rigged for sea, the following particulars are obtained : — 
‘ Minotaur.’ 
‘ Bellerophon.’

It follows from the above that the areas of the 
mean horizontal sections, which must be 
equal to the mean displacement in cubic feet divided by the mean draught of water, are 
‘ Minotaur.’ * Bellerophon.’ 
94 ^, 35 = 13333 sq.ft. 6898 * 3 -= 10407 sq. ft. 
The draughts of water which are found to correspond with water-line areas of these 
sections are, 
‘ Minotaur’ . . . 9*6 feet. 
‘Bellerophon’ . . 8-3 feet.
