HC Deb 17 March 1887 vol 312 c559

It has been decided to vary the design in three of the vessels in the following particulars:—

  1. 1. To wood-sheathe and copper the bottoms, so as to make the vessels capable of remaining afloat for long periods without serious fouling and consequent loss of speed.
  2. 2. To adopt horizontal engines, placed entirely below the protective deck.

These changes involve an increase in displacement and a slight decrease in maximum speed which are accepted in view of the special services for which the vessels are intended.

In armament, protection, and all other qualities, the conditions are the same in these as in the steel-bottomed ships.

The trials of these vessels will be made under the new regulations, with all weights aboard.
